Nationwide law enforcement impact on the pet bird trade in China.

Conservation enforcement is a direct strategy to combat illegal wildlife trade in open markets. Yet, its large-scale effectiveness has not been widely assessed due to the lack of extensive market data. Between August 2016 and June 2017, a national coordinated enforcement campaign led by the leading Chinese authority to combat illegal migratory bird trade coincided with the largest-ever pet bird market survey across China by voluntary birdwatchers before and after the enforcement, which served as a unique natural experiment. Across 73 markets from 22 Chinese provinces, the dataset contains 140,723 birds of 346 species from 48 families and recorded a drastic decline in bird abundance traded after enforcement. Notably, species protected under China's Wildlife Protection Law declined significantly, while commercially bred species increased, although responses to enforcement were spatially heterogeneous. Our model showed that the national protection level was the best predictor for the trend of traded species, even after accounting for confounding factors such as regional baseline enforcement pressure and wild native bird populations. However, the widely traded native songbirds were not offered adequate national protection. Future policies should consider the pet bird trade patterns, target key areas of trade, and develop a more systematic market survey design to monitor trade.

Advancing interdisciplinary science for disrupting wildlife trafficking networks.

Wildlife trafficking, whether local or transnational in scope, undermines sustainable development efforts, degrades cultural resources, endangers species, erodes the local and global economy, and facilitates the spread of zoonotic diseases. Wildlife trafficking networks (WTNs) occupy a unique gray space in supply chains-straddling licit and illicit networks, supporting legitimate and criminal workforces, and often demonstrating high resilience in their sourcing flexibility and adaptability. Authorities in different sectors desire, but frequently lack knowledge about how to allocate resources to disrupt illicit wildlife supply networks and prevent negative collateral impacts. Novel conceptualizations and a deeper scientific understanding of WTN structures are needed to help unravel the dynamics of interaction between disruption and resilience while accommodating socioenvironmental context. We use the case of ploughshare tortoise trafficking to help illustrate the potential of key advancements in interdisciplinary thinking. Insights herein suggest a significant need and opportunity for scientists to generate new science-based recommendations for WTN-related data collection and analysis for supply chain visibility, shifts in illicit supply chain dominance, network resilience, or limits of the supplier base.

14-Carbon demonstrates that some illegal ivory is being taken from government stockpiles.

The 14-carbon in animal tissues records the time that the tissues are formed; since the 1960s, using the "bomb curve" for 14C, the age of animal death can be determined accurately. Using animal tissue samples of known collection and formation dates for calibration, we determine the age of ivory samples from four ivory seizures made by law enforcement agencies between 2017 and 2019. The 14C measurements from these seizures show that most ivory in the illegal wildlife trade is from animals from recent poaching activities. However, one seizure has a large fraction of ivory that is more than 30 y old, consistent with markings on the tusks indicating they were derived from a government stockpile.

Uncovering the magnitude of African pangolin poaching with extensive nanopore DNA genotyping of seized scales.

Trade in pangolins is illegal, and yet tons of their scales and products are seized at various ports. These large seizures are challenging to process and comprehensively genotype for upstream provenance tracing and species identification for prosecution. We implemented a scalable DNA barcoding pipeline in which rapid DNA extraction and MinION sequencing were used to genotype a substantial proportion of pangolin scales subsampled from 2 record shipments seized in Singapore in 2019 (37.5 t). We used reference sequences to match the scales to phylogeographical regions of origin. In total, we identified 2346 cytochrome b (cytb) barcodes of white-bellied (Phataginus tricuspis) (from 1091 scales), black-bellied (Phataginus tetradactyla) (227 scales), and giant (Smutsia gigantea) (1028 scales) pangolins. Haplotype diversity was higher for P. tricuspis scales (121 haplotypes, 66 novel) than that for P. tetradactyla (22 haplotypes, 15 novel) and S. gigantea (25 haplotypes, 21 novel) scales. Of the novel haplotypes, 74.2% were likely from western and west-central Africa, suggesting potential resurgence of poaching and newly exploited populations in these regions. Our results illustrate the utility of extensively subsampling large seizures and outline an efficient molecular approach for rapid genetic screening that should be accessible to most forensic laboratories and enforcement agencies.

Revelación de la magnitud de la caza furtiva del pangolín africano mediante el genotipo extenso de nanoporos de ADN de escamas incautadas Resumen Aunque el mercado de pangolines es ilegal, se incautan toneladas de sus escamas y productos derivados en varios puertos comerciales. Es un reto procesar estas magnas incautaciones y obtener el genotipo completo para usarlo en la trazabilidad logística ascendente e identificación de la especie y así imponer sanciones. Implementamos una canalización escalable del código de barras de ADN en el cual usamos la extracción rápida de ADN y la secuenciación MinION para obtener el genotipo de una proporción sustancial de las escamas de pangolín submuestreadas en dos cargamentos incautados en 2019 en Singapur (37.5 t). Usamos secuencias referenciales para emparejar las escamas con las regiones filogeográficas de origen. Identificamos en total 2,346 códigos de citocromo b (cytb) del pangolín de vientre blanco (Phataginus tricuspis) (de 1,091 escamas), de vientre negro (P. tetradactyla) (227 escamas) y del pangolín gigante (Smutsia gigantea) (1,028 escamas). La diversidad de haplotipos fue mayor en las escamas de P. tricuspis (121 haplotipos, 66 nuevos) que en las de P. tetradactyla (22 haplotipos, 15 nuevos) y S. gigantea (25 haplotipos, 21 nuevos). De los haplotipos nuevos, el 74.2% probablemente provenía del occidente y centro­occidente de África, lo que sugiere un resurgimiento potencial de la caza furtiva y poblaciones recién explotadas en estas regiones. Nuestros resultados demuestran la utilidad de submuestrear extensivamente las grandes incautaciones y esboza una estrategia molecular eficiente para un análisis genético rápido que debería ser accesible para la mayoría de los laboratorios forenses y las autoridades de aplicación.

Assessing the legal, illegal, and gray ornamental trade of the critically endangered helmeted hornbill.

Monitoring wildlife trade dynamics is an important initial step for conservation action and demand reduction campaigns to reduce illegal wildlife trade. Studies often rely on one data source to assess a species' trade, such as seizures or the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) trade data. Each database provides useful information but is often incomplete. Combining information from multiple sources helps provide a more complete understanding of trade. A recent rapid increase in demand for helmeted hornbill (Rhinoplax vigil) casques (a brightly colored, solid keratinous rostrum) led to its uplisting to critically endangered on the International Union for Conservation of Nature Red List in 2015. However, there is little current information on what factors influence trade trends and what current levels of demand are. We combined data from CITES, seizure records, and previously underused, yet abundant, art and antique auction data to examine the global trade in helmeted hornbill casque products (HHPs). Three decades of auction data revealed that 1027 individual HHPs had been auctioned since 1992; total auction sales were over US$3 million from 1992 to 2021. The number of HHPs auctioned was greatest from 2011 to 2014, just after the global art boom (2009-2011), followed by a decline in volume and price. The auction data also revealed 2 possible markets for HHPs: true antique and speculative, defined by era, price, and trade patterns. Trends in illegal trade matched those of the auction market, but legal trade remained consistently low. Combining data sources from legal, illegal, and gray markets provided an overview of the dynamics of illegal trade in an endangered species. This approach can be applied to other wildlife markets to provide a more complete understanding of trade and demand at the market level to inform future demand reduction campaigns.

Análisis del comercio ornamental legal, ilegal y gris del cálao con casco, especie en peligro crítico Resumen El monitoreo de la dinámica del comercio de especies silvestres es un paso inicial importante para las acciones de conservación y las campañas de reducción de la demanda destinadas a reducir el comercio ilegal de especies silvestres. Los estudios suelen basarse en una sola fuente de datos para evaluar el comercio de una especie, como las incautaciones o los datos comerciales de la Convención sobre el Comercio Internacional de Especies Amenazadas de Fauna y Flora Silvestres (CITES). Cada base de datos proporciona información útil, pero a menudo incompleta. La combinación de información procedente de varias fuentes ayuda a comprender mejor el comercio. Un reciente y rápido aumento de la demanda de cascos (un casquete queratinoso, sólido y de colores brillantes) de cálao con casco (Rhinoplax vigil) hizo que en 2015 se incluyera en la Lista Roja de la Unión Internacional para la Conservación de la Naturaleza como especie en peligro crítico. Sin embargo, existe poca información actual sobre los factores que influyen en las tendencias del comercio y cuáles son los niveles actuales de demanda. Combinamos datos de CITES, registros de incautaciones y datos de subastas de arte y antigüedades previamente poco utilizados, aunque abundantes, para examinar el comercio mundial de productos de casquetes de cálao con casco (CCC). Tres décadas de datos de subastas revelaron que se habían subastado 1,027 CCC individuales desde 1992; las ventas totales en subasta superaron los tres millones de dólares entre 1992 y 2021. El número de CCC subastados fue mayor entre 2011 y 2014, justo después del boom del arte (2009­2011), seguido de un descenso en volumen y precio. Los datos de las subastas también revelaron dos posibles mercados para los CCC: el de las verdaderas antigüedades y el especulativo, definidos por la época, el precio y los patrones de comercio. Las tendencias del comercio ilegal coincidieron con las del mercado de subastas, pero el comercio legal se mantuvo bajo con constancia. Con la combinación de fuentes de datos de mercados legales, ilegales y grises, nuestros datos proporcionaron una visión general de la dinámica del comercio ilegal de una especie amenazada. Este enfoque puede aplicarse a otros mercados de especies silvestres para obtener un conocimiento más completo del comercio y la demanda a nivel de mercado que sirva de base a futuras campañas de reducción de la demanda.

Expert assessment of illegal collecting impacts on Venus flytraps and priorities for research on illegal trade.

Illegal collecting of wild Venus flytraps (Dionaea muscipula) for the horticultural trade represents a persistent threat to populations of the species across their endemic range in the coastal plain of North and South Carolina (United States). Although wild collecting of Venus flytraps is not a novel threat, there has been very little research on the impacts of collecting on the species' conservation to date or why an illegal trade persists alongside a legal one. We drew on qualitative expert stakeholder elicitation to contextualize the threat of illegal collecting to the long-term conservation of Venus flytraps in relation to other anthropogenic threats. Expert elicitation included botanical and conservation researchers, cognizant state and federal agency staff, land managers, and conservation nonprofit actors. The workshop included mapping of supply chain structures and prioritization of social and environmental harms. Expert consensus determined illegal collecting is an ongoing problem for Venus flytrap conservation, but habitat destruction, degradation, and fire suppression are the most significant threats to flytrap conservation. Supply chain analysis showed that observable social and environmental harms of the trade are focused at the supply stage and that less is known about transit and demand stages. Key research gaps identified include a lack of understanding of plant laundering practices relevant to a range of desirable plant taxa; the role of commercial nurseries in illicit horticultural supply chains; motivations for engaging in Venus flytrap collecting; and the persistent demand for illegally harvested plants when cultivated, legally obtainable plants are readily available. Our findings and methodology are relevant to a range of ornamental plants affected by illegal trade for which robust social data on illegal collecting drivers are lacking.

Evaluación experta del impacto de la colecta ilegal de venus atrapamoscas y las prioridades de investigación sobre el mercado ilegal Resumen La colecta ilegal de venus atrapamoscas (Dionaea muscipula) silvestres para el mercado de horticultura representa una amenaza constante para las poblaciones de la especie a lo largo de su distribución endémica en la planicie costera de Carolina del Norte y del Sur, Estados Unidos. Aunque esta colecta no es una amenaza novedosa, a la fecha se ha investigado muy poco sobre su impacto en la conservación de la especie o por qué el mercado ilegal persiste a la par del legal. Partimos del conocimiento cualitativo de los actores expertos para contextualizar la amenaza de la colecta ilegal para la conservación a largo plazo de la venus atrapamoscas en relación con otras amenazas antropogénicas. Este conocimiento involucró a investigadores de la conservación y la botánica, personal consciente de agencias federales y estatales y actores de la conservación sin fines de lucro. El taller incluyó el mapeo de las estructuras de las cadenas de suministro y la priorización de los daños sociales y ambientales. El consenso de los expertos determinó que la colecta ilegal es un problema continuo para la conservación de la venus atrapamoscas, pero la destrucción y degradación del hábitat, así como la contención de incendios son las amenazas más significativas. El análisis de las cadenas de suministro mostró que los daños ambientales y sociales observables en el mercado se enfocan en la fase de suministro y que se sabe poco sobre las fases de tránsito y demanda. Los vacíos de investigación más importantes incluyen la falta de entendimiento de las prácticas de lavado de plantas relevantes para un rango de taxones deseables de plantas; el papel de los viveros comerciales en las cadenas de suministro de la horticultura ilícita; los motivos para participar en la colecta de venus atrapamoscas; y la demanda continua de plantas cosechadas ilegalmente cuando ya hay disponibilidad de plantas cultivadas que se obtienen legalmente. Nuestros descubrimientos y metodología son relevantes para una gama de plantas ornamentales afectadas por el mercado ilegal para las cuales hay carencia de datos sociales sólidos sobre los factores de colecta ilegal.

Creating a more inclusive approach to wildlife trade management.

Global wildlife trade involves a diverse array of species. Although sustainable trade underpins livelihoods for communities worldwide, unsustainable trade, whether legal or illegal, threatens thousands of species and can lead to extinctions. From plants and fungi to fish, amphibians, mammals, invertebrates, and reptiles, a diverse array of species across taxa are affected by trade. Attention to wildlife trade has increased in recent years, but its focus has largely remained on a narrow range of high-profile species, with taxa deemed less charismatic frequently overlooked, despite some having significant trade volumes and levels of threat to wild populations. These biases can hamper effective policy interventions, reduce awareness of wider threats from trade, and prevent conservation efforts from focusing on the most pressing issues. It is important to broaden the scope of research and policy discussions and create a more inclusive approach to trade management. The diversity of approaches to wildlife trade can be improved by expanding monitoring of trade to a wider variety of taxa; collecting fundamental ecological data to underpin assessments of trade sustainability; improving and codesigning conservation interventions with key stakeholders and trade actors; and developing appropriate strategies for managing the supply, trade, and demand in diverse wildlife products to ensure species and livelihoods are protected.

Creación de un enfoque más inclusivo para la gestión del mercado de vida silvestre Resumen El mercado global de vida silvestre involucra a una diversa gama de especies. Mientras que el mercado sustentable apoya al sustento de las comunidades, el mercado insostenible, sea legal o ilegal, amenaza a miles de especies y puede causar extinciones. Desde plantas y hongos hasta peces, anfibios, mamíferos, invertebrados y reptiles, una diversa gama de especies de diferentes taxones se ve afectada por el mercado. Aunque la atención hacia el mercado de vida silvestre ha aumentado en años recientes, su enfoque ha sido principalmente en especies de perfil elevado, por lo que se suele ignorar a taxones considerados menos carismáticos, a pesar de que algunos cuenten con importantes volúmenes de comercio o niveles de amenaza para las poblaciones silvestres. Estos sesgos pueden complicar las intervenciones políticas eficientes, reducir la conciencia sobre las amenazas mayores del comercio y prevenir que los esfuerzos de conservación se enfoquen en los temas más urgentes. Es importante que se amplíe el objetivo de la investigación y las discusiones políticas y se cree un enfoque más inclusivo para la gestión del mercado. Se puede mejorar la diversidad de enfoques sobre el mercado de vida silvestre con la expansión del monitoreo del mercado hacia una mayor variedad de taxones; la colecta de datos ecológicos fundamentales para sostener los análisis sobre la sustentabilidad del mercado; la mejora y el diseño de las intervenciones de conservación conjuntamente con los actores clave del mercado; y el desarrollo de estrategias adecuadas para la gestión de la oferta, comercio y demanda de diferentes productos de vida silvestre para asegurar que se protejan las especies y el sustento de las comunidades.

A synthesis of wild animal-related trade laws in some of the world's most biodiverse countries.

We examined the laws and legal provisions governing the commercial trade of terrestrial wild fauna across the trade chain in some of the world's megadiverse countries and how these relate to key animal welfare and conservation concerns. Over the past century, an increase in the quantity and complexity of laws related to commercial wildlife trade has been observed in the 11 focal countries examined. Our review identified 95 laws with 560 provisions adopted since 1910 across these countries. Surprisingly, the level of biological diversity in a country does not correlate with the extent of legislation addressing wildlife trade. Moreover, legislation is unevenly distributed across different stages of the wildlife trade chain, with more provisions on extraction and transportation compared to captive management. Notably, animal welfare considerations are relatively underrepresented in legislation related to wildlife trade, despite their broad implications for public health and economies. Urgent legislative action is needed to meet global biodiversity targets and respond to the challenges posed by the growing scale and complexity of the wildlife trade. Recommendations are made to streamline legislation, consider the legal status of wild animals, and address gaps in enforcement mechanisms. We conclude that alignment of national and international regulations is crucial for the effective protection of both wild animal populations and individual animals' welfare in the context of commercial trade. Further research is needed to assess the effectiveness of existing laws, bridge legal gaps, and address diverse concerns related to wildlife trade, including public health and the rights of local communities.

Drivers and facilitators of the illegal killing of elephants across 64 African sites.

Ivory poaching continues to threaten African elephants. We (1) used criminology theory and literature evidence to generate hypotheses about factors that may drive, facilitate or motivate poaching, (2) identified datasets representing these factors, and (3) tested those factors with strong hypotheses and sufficient data quality for empirical associations with poaching. We advance on previous analyses of correlates of elephant poaching by using additional poaching data and leveraging new datasets for previously untested explanatory variables. Using data on 10 286 illegally killed elephants detected at 64 sites in 30 African countries (2002-2020), we found strong evidence to support the hypotheses that the illegal killing of elephants is associated with poor national governance, low law enforcement capacity, low household wealth and health, and global elephant ivory prices. Forest elephant populations suffered higher rates of illegal killing than savannah elephants. We found only weak evidence that armed conflicts may increase the illegal killing of elephants, and no evidence for effects of site accessibility, vegetation density, elephant population density, precipitation or site area. Results suggest that addressing wider systemic challenges of human development, corruption and consumer demand would help reduce poaching, corroborating broader work highlighting these more ultimate drivers of the global illegal wildlife trade.

Prevalence and perspectives of illegal trade in cacti and succulent plants in the collector community.

Although illegal wildlife trade (IWT) represents a serious threat to biodiversity, research into the prevalence of illegal plant collection and trade remains scarce. Because cacti and succulents are heavily threatened by overcollection for often illegal, international ornamental trade, we surveyed 441 members of the cacti and succulent hobbyist collector community with a mixed quantitative and qualitative approach. We sought to understand collector perspectives on the Convention on the International Trade in Endangered Species of Wild Flora and Fauna (CITES) and on the threats IWT poses to cactus and succulent conservation. Most respondents (74% of 401 respondents) stated that illegal collection in cacti and succulents represents a "very serious problem" and that the problem of wild plant collection is increasing (72% of 319 respondents). Most forms of illegal collection and trade were seen as very unacceptable by respondents. Self-reported noncompliance with CITES rules was uncommon (11.2% of 418 respondents); it remains a persistent problem in parts of the cacti and succulent hobbyist community. People engaging in rule breaking, such as transporting plants without required CITES documents, generally did so knowingly. Although 60.6% of 381 respondents regarded CITES as a very important tool for conservation, sentiment toward CITES and its efficacy in helping species conservation was mixed. Collectors in our survey saw themselves as potentially playing important roles in cactus and succulent conservation, but this potential resource remains largely untapped. Our results suggest the need for enhanced consultation with stakeholders in CITES decision-making. For challenging subjects like IWT, developing evidence-based responses demands deep interdisciplinary engagement, including assessing the conservation impact of species listings on CITES appendices.

Aunque el mercado ilegal de especies (MIE) representa una amenaza seria para la biodiversidad, son escasas las investigaciones sobre la prevalencia del intercambio y la colecta ilegal de plantas. Ya que las cactáceas y suculentas están amenazadas seriamente por la sobrecolección, generalmente para el mercado ornamental internacional e ilegal, encuestamos mediante una estrategia cualitativa y cuantitativa a 441 miembros de la comunidad de aficionados a coleccionar estas plantas. Buscamos entender las perspectivas que tienen los coleccionistas sobre la Convención sobre el Comercio Internacional de Fauna y Flora Silvestres (CITES) y sobre las amenazas que el MIE representa para la conservación de las cactáceas y las suculentas. La mayoría de los respondientes (74% de 401) mencionaron que la recolección ilegal de estas plantas representa un "problema muy serio" y que el problema de la recolección de plantas silvestres está en aumento (72% de 319 respondientes). Casi todas las formas de mercado y colecta ilegal fueron consideradas como inaceptables por los respondientes. El no cumplimiento autoreportado de las reglas de la CITES no fue recurrente (11.2% de 418 respondientes), pero permanece como un problema persistente en algunos sectores de la comunidad de aficionados a la colección de estas plantas. Las personas que rompieron las reglas, como con el transporte de plantas sin los documentos CITES requeridos, en su mayoría lo hicieron conscientemente. Aunque el 60.6% de los 381 respondientes consideraron la CITES como una herramienta muy importante para la conservación, los sentimientos hacia ella y su eficiencia en el apoyo a la conservación de especies fueron encontrados. Los coleccionistas de nuestra encuesta se reconocieron como actores potencialmente importantes en la conservación de las cactáceas y las suculentas, pero este recurso potencial permanece desaprovechado en su mayoría. Nuestros resultados sugieren que es necesaria una consulta reforzada con los actores en las decisiones de la CITES. Para temas exigentes como el MIE, el desarrollo de respuestas basadas en evidencias demanda una participación interdisciplinaria profunda, incluyendo la evaluación del impacto de conservación que tienen los listados de especies en los apéndices de CITES. Prevalencia y perspectivas del mercado ilegal de cactáceas y plantas suculentas en la comunidad de coleccionistas.

Tracking Chinese newspaper coverage of elephant ivory through topic modeling.

Mass media worldwide has contributed to increasing awareness of the illegal wildlife trade and its significant impact on wildlife conservation. We used mass media coverage as a proxy for macro-level public opinion to analyze the media framing of elephant ivory in 6394 Chinese newspaper articles published from 2000 to 2021 and thus determine the effects of wildlife policies on public opinion. We focused on 2 events: the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) approval of China as a trading partner in the purchase and import of ivory stockpiles from Africa in July 2008 and the Chinese government's announcement of a domestic ivory ban in December 2016. Using latent Dirichlet allocation topic modeling, we identified 8 topics about elephant ivory and grouped them into 3 frames: ivory arts and culture, ivory crimes, and elephant conservation. Over the last 2 decades, topics related to ivory crimes remained the most prevalent in news articles. Topics about ivory arts and culture showed a significant shift in media salience before and after the 2 events (from 0.44 to 0.19 and from 0.08 to 0.15, respectively, p < 0.05), whereas the other 2 frames did not change significantly. Contrary to popular belief, our results indicated that Chinese macro-level public opinion on ivory had become more negative following the CITES approval of ivory importation and less negative after the ivory ban announcement, at least for certain periods. The relationship between mass media, public opinion, and wildlife trade policies is complex and requires further examination of the sociopolitical dynamics that influence media narratives. Our results showed the value of topic modeling in monitoring and assessing media representations of wildlife issues in the era of big data. Conservationists should remain vigilant of mass media coverage and collaborate with media practitioners to produce comprehensive narratives on wildlife issues if resources permit.

Los medios masivos han contribuido a una mayor conciencia mundial del mercado ilegal de fauna y el impacto significativo que tiene sobre la conservación. Usamos la cobertura de los medios masivos como sustituto de la opinión pública a nivel macro para analizar el encuadre mediático que le dan al marfil 6,394 artículos publicados en periódicos chinos entre el 2000 y 2021 para así determinar los efectos que tienen las políticas de fauna sobre la opinión pública. Nos enfocamos en dos eventos: la autorización que dio la Convención sobre el Comercio Internacional de Especies Amenazadas (CITES) a China como socio comercial en la compra e importación de reservas de marfil desde África en julio de 2008 y la prohibición doméstica de marfil anunciada por el gobierno chino en diciembre de 2016. Usamos el modelado de asignación latente de Dirichlet para identificar ocho temas sobre el marfil y los agrupamos en tres encuadres: arte y cultura del marfil, crimen del marfil y conservación de elefantes. Durante las últimas dos décadas, los temas relacionados con los crímenes del marfil fueron los más prevalentes en los artículos periodísticos. Los temas relacionados al arte y cultura del marfil mostraron un cambio significativo en la relevancia mediática antes y después de los dos eventos (de 0.44 a 0.19 y de 0.08 a 0.15, respectivamente, p<0.05), mientras que los otros dos encuadres no cambiaron significativamente. Contrario a las creencias populares, nuestros resultados indicaron que la opinión pública a nivel macro sobre el marfil en China se ha vuelto más negativa después de la autorización de CITES y menos negativa después de la prohibición del marfil, al menos durante ciertos periodos. La relación entre los medios masivos, la opinión pública y las políticas del comercio de fauna es compleja y requiere un análisis más profundo de las dinámicas sociopolíticas que influyen sobre las narrativas mediáticas. Nuestros resultados muestran el valor del modelado de temas en el monitoreo y evaluación de la representación en medios de los temas sobre fauna en tiempos de los macrodatos. Los conservacionistas deberían permanecer atentos a la cobertura de los medios masivos y colaborar con los profesionales de los medios para producir narraciones completas sobre la fauna si los recursos lo permiten.

Unraveling the mystery of confiscated "jackal horns" in India using wildlife forensic tools.

Internationally, illegal wildlife trade involves highly prized and charismatic species and their derivatives. At the same time, common or less known species and their parts are also encountered but receive less attention than charismatic species. Given the increasing demand for wildlife products in many parts of the world, profit, and short supply, many fake articles derived from domestic or wild animals are frequently encountered in the wildlife trade. Jackal horn (locally known as "Siyar or Gidar singhi") is one such fake item widely used in sorcery and other occult practices available through offline and online trading platforms within India. We used a combination of morphological, microscopic hair, and molecular approaches (Cyt b and 16 s rRNA genes) to reveal the true identity of confiscated "jackal horns" (n = 342). Detailed morphological study of the jackal horns showed that it varied in size, shape, color of hair, attachment material, and filling material. The microscopic hair and molecular approaches revealed that all the items sold as jackal horns were fake and made up of protected wild species and domestic animals. Our results confirm the use of the biological samples from few wild species protected under the Wild Life (Protection) Act, 1972, of India. Therefore, the law enforcement agencies are cautioned to get forensic opinions while dealing with such counterfeit items.

The welfare of wildlife: an interdisciplinary analysis of harm in the legal and illegal wildlife trades and possible ways forward.

Wildlife trade-both legal and illegal-is an activity that is currently the focus of global attention. Concerns over the loss of biodiversity, partly stemming from overexploitation, and the corona virus pandemic, likely originating from wildlife trade, are urgent matters. These concerns though centre on people. Only sometimes does the discussion focus on the wildlife traded and their welfare. In this article, we make the case as to why welfare is an important component of any discussion or policy about wildlife trade, not only for the interests of the wildlife, but also for the sake of humans. We detail the harm in the trade as well as the current welfare provisions, particularly in relation to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which guide global transport and trade. There are a number of ways that the current approach to wildlife welfare could be improved, and we propose ways forward in this regard.

Poacher-population dynamics when legal trade of naturally deceased organisms funds anti-poaching enforcement.

Can a regulated, legal market for wildlife products protect species threatened by poaching? It is one of the most controversial ideas in biodiversity conservation. Perhaps the most convincing reason for legalizing wildlife trade is that trade revenue could fund the protection and conservation of poached species. In this paper, we examine the possible poacher-population dynamic consequences of legal trade funding conservation. The model consists of a manager scavenging carcasses for wildlife product, who then sells the product, and directs a portion of the revenue towards funding anti-poaching law enforcement. Through a global analysis of the model, we derive the critical proportion of product the manager must scavenge, and the critical proportion of trade revenue the manager must allocate towards increased enforcement, in order for legal trade to lead to abundant long-term wildlife populations. We illustrate how the model could inform management with parameter values derived from the African elephant literature, under a hypothetical scenario where a manager scavenges elephant carcasses to sell ivory. We find that there is a large region of parameter space where populations go extinct under legal trade unless a significant portion of trade revenue is directed towards protecting populations from poaching. The model is general and therefore can be used as a starting point for exploring the consequences of funding many conservation programs using wildlife trade revenue.

Building a global taxonomy of wildlife offenses.

Most countries have many pieces of legislation that govern biodiversity, including a range of criminal, administrative, and civil law provisions that state how wildlife must be legally used, managed, and protected. However, related debates in conservation, such as about enforcement, often overlook the details within national legislation that define which specific acts are illegal, the conditions under which laws apply, and how they are sanctioned. Based on a review of 90 wildlife laws in 8 high-biodiversity countries with different legal systems, we developed a taxonomy that describes all types of wildlife offenses in those countries. The 511 offenses are organized into a hierarchical taxonomy that scholars and practitioners can use to help conduct legal analyses. This is significant amidst competing calls to strengthen, deregulate, and reform wildlife legislation, particularly in response to fears over zoonotic threats and large-scale biodiversity loss. It can be used to provide more nuance legal analyses and facilitate like-for-like comparisons across countries, informing processes to redraft conservation laws, review deregulation efforts, close loopholes, and harmonize legislation across jurisdictions. We applied the taxonomy in a comparison of sanctions in 8 countries for hunting a protected species. We found not only huge ranges in fines (US$0 to $200,000) and imprisonment terms (1.5 years to life imprisonment), but also fundamentally different approaches to designing sanctions for wildlife offenses. The taxonomy also illustrates how future legal taxonomies can be developed for other environmental issues (e.g., invasive species, protected areas).

Creación de una Taxonomía Mundial de Ofensas a la Fauna Resumen La mayoría de los países tienen muchos instrumentos de legislación que gobiernan la biodiversidad, incluyendo una gama de disposiciones de leyes criminales, administrativas y civiles que declaran cómo se debe usar, manejar y proteger legalmente a la fauna. Sin embargo, los debates relacionados a la conservación, como el cumplimiento de las leyes, generalmente ignoran los detalles dentro de la legislación nacional que definen cuáles actos específicos son ilegales, las condiciones bajo las cuales aplican las leyes y cómo son sancionadas. Con base en una revisión de 90 leyes relacionadas con la fauna en ocho países con una gran biodiversidad y diferentes sistemas legales, desarrollamos una taxonomía que describe todos los tipos de ofensas a la fauna en aquellos países. Las 511 ofensas están organizadas en una taxonomía jerárquica que los académicos y los practicantes pueden usar para ayudar a realizar análisis legales. Lo anterior es significativo en medio de las peticiones competitivas por fortalecer, desregular y reformar la legislación de la fauna, particularmente como respuesta al miedo por las amenazas zoonóticas y la pérdida a gran escala de la biodiversidad. La taxonomía puede usarse para proporcionar análisis legales más matizados y para facilitar las comparaciones igual-por-igual entre los países, informar los procesos para reformular las leyes de conservación, revisar los esfuerzos por desregular, cerrar los vacíos legales y armonizar la legislación entre las jurisdicciones. Aplicamos la taxonomía en una comparación de las sanciones aplicadas en ocho países a la caza de especies protegidas. Encontramos no sólo una gama enorme de multas (de US$0 a $200,000) y términos de encarcelamiento (de 1.5 años a sentencias de por vida), sino también estrategias fundamentalmente diferentes para el diseño de las sanciones para las ofensas a la fauna. La taxonomía también ilustra cómo pueden desarrollarse las siguientes taxonomías legales para otros temas ambientales (p. ej.: especies invasoras, áreas protegidas).

Motivations for the use and consumption of wildlife products.

The dominant approach to combating the illegal wildlife trade has traditionally been to restrict the supply of wildlife products. Yet conservationists increasingly recognize the importance of implementing demand-side interventions that target the end consumers in the trade chain. Their aim is to curb the consumption of wildlife or shift consumption to more sustainable alternatives. However, there are still considerable knowledge gaps in understanding of the diversity of consumer motivations in the context of illegal wildlife trade, which includes hundreds of thousands of species, different uses, and diverse contexts. Based on consultation with multiple experts from a diversity of backgrounds, nationalities, and focal taxa, we developed a typology of common motivations held by wildlife consumers that can be used to inform conservation interventions. We identified 5 main motivational categories for wildlife use: experiential, social, functional, financial, and spiritual, each containing subcategories. This framework is intended to facilitate the segmentation of consumers based on psychographics and allow the tailoring of interventions-whether behavior change campaigns, enforcement efforts, or incentive programs-to the specific context in which they will be used. Underlining the importance of consumer research and collaborating with local actors is an important step toward promoting a more systematic approach to the design of demand reduction interventions.

Motivaciones para el Uso y Consumo de Productos de Fauna Resumen Tradicionalmente, la estrategia dominante para combatir el mercado ilegal de fauna ha sido restringir la oferta de productos de fauna. Aun así, los conservacionistas cada vez reconocen más la importancia de implementar intervenciones por el lado de la demanda que se enfoquen en los consumidores finales en la cadena de mercado. Su objetivo es reducir el consumo de fauna o redirigir ese consumo hacia alternativas más sustentables. Sin embargo, todavía existen vacíos de conocimiento en el entendimiento de la diversidad de motivos para los consumidores dentro del contexto del mercado ilegal de fauna, el cual incluye cientos de miles de especies, diferentes usos y contextos diversos. Con base en consultas a varios expertos con una diversidad de antecedentes, nacionalidades y taxones de enfoque desarrollamos una tipología de motivos comunes que tienen los consumidores de fauna que pueden usarse para orientar las intervenciones de conservación. Identificamos cinco categorías principales de motivos para el uso de fauna: vivencial, social, funcional, financiero y espiritual, cada uno con subcategorías. Este marco de trabajo tiene la intención de facilitar la segmentación de consumidores con base en psicográficos y permitir la personalización de las intervenciones - sean campañas de cambios en el comportamiento, esfuerzos por hacer cumplir las reglas o programas de incentivos - al contexto específico en el que serán utilizadas. Resaltar la importancia de los estudios de mercado y la colaboración con los actores locales es un paso importante hacia la promoción de una estrategia más sistemática para el diseño de intervenciones para reducir la demanda.

Scale of the issue: Mapping the impact of the COVID-19 lockdown on pangolin trade across India.

Recent studies have linked COVID-19 induced restrictions to an increase in wildlife crime, with severe yet unknown implications for severely threatened taxa like pangolins. We analyze publicly available online seizure reports involving pangolins across India before (2018-2019) and during the pandemic (March-August 2020), using a longitudinal study design to estimate how lockdowns have impacted pangolin trade. Our analysis indicates a significant increase in seizures reported during the lockdown months of March to August 2020, in comparison to the same period in 2018 and 2019. We discuss the drivers behind this spike in pangolin trade and offer potential conservation measures.

The scale of Nigeria's involvement in the trans-national illegal pangolin trade: Temporal and spatial patterns and the effectiveness of wildlife trade regulations.

The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) prohibits commercial trans-national trade in pangolin specimens. However, African pangolins are continually trafficked to Asia for traditional medicine, with Nigeria considered a key hub. Using reported Nigeria-linked pangolin seizure data and interviews with Nigerian law enforcement officials, we a) characterised Nigeria's involvement in global pangolin trafficking January 2010-September 2021, particularly observing trafficking trends after pangolin's CITES Appendix I listing; b) estimated the minimum number of pangolins whose scales are in Nigeria-linked seizures January 2010-September 2021, and; c) assessed ongoing efforts within Nigeria to curb pangolin trafficking. Nigeria-linked seizures involved 190,407 kg of pangolin derivatives (99.9% scales) from a minimum of 799,343 pangolins (95% confidence interval; 625,944-996,353) of four species (see caveats in Methods). All shipments confiscated in transit were destined for Asia, with a rapid increase in the mass of maritime shipments over time. Furthermore, stockpiling of pangolin derivatives for overseas shipment is perhaps a prominent trafficking model in Nigeria. Nigeria's law enforcement efforts improved from 2017, the same year Nigeria apparently began playing a hub role. The impact of pangolin's CITES Appendix I listing on pangolin trafficking was unclear, as the marked rise in seizures from 2017 when the listing became effective, coincided with improvements in Nigerian law enforcement efforts. COVID-19-induced travel restrictions likely reduced trafficking activities in 2020 but activities may have fully resumed in 2021. This study provides new information to inform effective enforcement and policy formulation efforts to protect African pangolins.

Tape lures swell bycatch on a Mediterranean island harbouring illegal bird trapping.

Mediterranean islands provide shelter and sustenance for millions of migrating birds each year. Humans have historically exploited bird migration through hunting. In Cyprus, trapping birds during their migratory peak is considered a tradition, but has long been against the law. Illegal bird trapping is lucrative, however, with trappers using tape lures that broadcast birdsong to increase capture rates. It results in the slaughter of millions of birds each year. Yet, scientific studies quantifying capture rates of target and nontarget species using methods employed by trappers are lacking. Here, we show using playback experiments that tape lures lead to an order of magnitude greater capture rates of target species, but also significantly increase bycatch, which may include species of conservation concern. Conservation efforts focusing on minimizing illegal bird killing should also consider tape lures and their contribution to the overall impact of trapping on avian populations.

Development and characterization of 20 polymorphic microsatellite markers for the white-bellied pangolin Phataginus tricuspis (Mammalia, Pholidota).

Pangolins, or scaly anteaters, have recently been flagshiped as one of the most illegally traded mammals, and as a corollary, as potential intermediate hosts at the origin of the COVID-19 pandemic. In order to improve the traceability of their trade, we developed 20 polymorphic microsatellite loci for the white-bellied pangolin (Phataginus tricuspis), the species most frequently found on African bushmeat markets. We genotyped 24 white-bellied pangolins from the Douala market, Cameroon, originating from the Ebo forest c. 75 km north-east of Douala. The number of alleles per locus ranged from 4 to 12 (mean = 6.95), and mean observed and expected heterozygosities were 0.592 (0.208-0.875) and 0.671 (0.469-0.836), respectively. Genetic diversity was higher than that cross-estimated from microsatellite loci developed for other species of pangolins. Two loci deviated from Hardy-Weinberg equilibrium and two loci showed linkage disequilibrium. Genetic variance (PCoA) was increased with the addition of 13 pangolins of unknown origin, possibly suggesting that the Douala market is fed from differentiated source populations of white-bellied pangolins. Each of the 37 individuals had a unique multilocus genotype. The unbiased probability of identity (uPI) and the probability of identity among siblings (PIsibs) were both very low (uPI = 8.443 e-21; PIsibs = 1.011 e-07). Only five microsatellite loci were needed to reach the conservative value of PIsibs < 0.01, overall indicating a powerful discriminating power of our combined loci. These 20 newly developed microsatellite loci might prove useful in tracing the local-to-global trade of the white-bellied pangolin, and will hopefully contribute to the DNA-assisted implementation of future conservation strategies at reasonable costs.
