Population assessment of the Endangered Kashmir Gray Langur (Semnopithecus ajax, Pocock 1928) using the double-observer method.

Primates are among the most threatened taxa globally, therefore, there is a need to estimate and monitor their populations. Kashmir Gray Langur Semnopithecus ajax is an endangered species for which there is no population estimate. We used double-observer method to estimate its population size in the Kashmir region of North-Western Himalaya. We walked 1284 km across 31 survey blocks spanning all three divisions of Kashmir viz., North, Central, and South Kashmir, covering an area of 411 km2. We counted a minimum of 1367 individual langurs from 27 groups. The detection probability for observer 1 (0.719) and observer 2 (0.656) resulted in a population estimate of 1496 (95% confidence interval [CI] 1367-1899) across 30 groups (with a mean group size of 51), giving a density estimate of 3.64 (3.33-4.62) langurs/km². We found double-observer surveys to be suitable for the population estimation of langurs, and we make recommendations on how to effectively conduct primate surveys, especially in mountainous ecosystems. Our records extend the species distribution range beyond stated by the International Union for Conservation of Nature. Our findings also highlight that the Kashmir Himalaya is a stronghold of the species, where conservation efforts should focus.

Recognizing reflexivity among conservation practitioners.

When deciding how to conserve biodiversity, practitioners navigate diverse missions, sometimes conflicting approaches, and uncertain trade-offs. These choices are based not only on evidence, funders' priorities, stakeholders' interests, and policies, but also on practitioners' personal experiences, backgrounds, and values. Calls for greater reflexivity-an individual or group's ability to examine themselves in relation to their actions and interactions with others-have appeared in the conservation science literature. But what role does reflexivity play in conservation practice? We explored how self-reflection can shape how individuals and groups conserve nature. To provide examples of reflexivity in conservation practice, we conducted a year-long series of workshop discussions and online exchanges. During these, we examined cases from the peer-reviewed and gray literature, our own experiences, and conversations with 10 experts. Reflexivity among practitioners spanned individual and collective levels and informal and formal settings. Reflexivity also encompassed diverse themes, including practitioners' values, emotional struggles, social identities, training, cultural backgrounds, and experiences of success and failure. Reflexive processes also have limitations, dangers, and costs. Informal and institutionalized reflexivity requires allocation of limited time and resources, can be hard to put into practice, and alone cannot solve conservation challenges. Yet, when intentionally undertaken, reflexive processes might be integrated into adaptive management cycles at multiple points, helping conservation practitioners better reach their goals. Reflexivity could also play a more transformative role in conservation by motivating practitioners to reevaluate their goals and methods entirely. Reflexivity might help the conservation movement imagine and thus work toward a better world for wildlife, people, and the conservation sector itself.

Reconocimiento de la reflexividad entre los practicantes de la conservación Resumen Cuando se decide cómo conservar la biodiversidad, quienes la practican sortean varias misiones, algunas veces con enfoques contrastantes y compensaciones inciertas. Estas elecciones no se basan solamente en las evidencias, prioridades de los financiadores, los intereses de los actores y las políticas, sino también en las experiencias personales, formación y valores de los practicantes. En la literatura sobre las ciencias de la conservación han surgido llamados para una mayor reflexividad - la habilidad individual o grupal para examinarse a sí mismo en relación con sus acciones e interacciones con otros. Pero ¿cuál es el papel de la reflexividad en la práctica de la conservación? Para responder esto, exploramos cómo la autorreflexión puede determinar cómo ocurre la conservación individual y grupal de la naturaleza. Realizamos una serie de talleres de discusión e intercambios virtuales durante un año para ejemplificar la reflexividad en la práctica de la conservación. Durante estas sesiones examinamos casos de la literatura gris y revisada por pares, nuestras propias experiencias y conversaciones con diez expertos. La reflexividad de los practicantes abarcó niveles individuales y colectivos y escenarios formales e informales. La reflexividad también comprendió diferentes aspectos de los practicantes, como los valores, conflictos emocionales, identidad social, preparación, contexto cultural y experiencias exitosas y fallidas. Los procesos reflexivos también tienen limitaciones, riesgos y costos. La reflexividad informal e institucionalizada requiere la distribución de tiempo y recursos limitados, puede ser difícil de poner en práctica y no puede resolver los retos de conservación por sí sola. Aun así, cuando se realizan intencionalmente, los procesos reflexivos pueden integrarse a los ciclos de manejo adaptativo en varios puntos, lo que ayuda a quienes practican la conservación a lograr sus metas de mejor manera. La reflexividad también podría tener un papel transformador en la conservación al motivar a los practicantes a reevaluar completamente sus metas y métodos. La reflexividad podría ayudar al movimiento de conservación a imaginar, y por lo tanto trabajar para tener, un mundo mejor para la vida silvestre, las personas y el propio sector de la conservación.

Supporting conservationists' mental health through better working conditions.

Biodiversity conservation work can be challenging but rewarding, and both aspects have potential consequences for conservationists' mental health. Yet, little is known about patterns of mental health among conservationists and its associated workplace protective and risk factors. A better understanding might help improve working conditions, supporting conservationists' job satisfaction, productivity, and engagement, while reducing costs from staff turnover, absenteeism, and presenteeism. We surveyed 2311 conservation professionals working in 122 countries through an internet survey shared via mailing lists, social media, and other channels. We asked them about experiences of psychological distress, working conditions, and personal characteristics. Over half were from and worked in Europe and North America, and most had a university-level education, were in desk-based academic and practitioner roles, and responded in English. Heavy workload, job demands, and organizational instability were linked to higher distress, but job stability and satisfaction with one's contributions to conservation were associated with lower distress. Respondents with low dispositional and conservation-specific optimism, poor physical health, and limited social support, women, and early-career professionals were most at risk of distress in our sample. Our results flag important risk factors that employers could consider, although further research is needed among groups underrepresented in our sample. Drawing on evidence-based occupational health interventions, we suggest measures that could promote better working conditions and thus may improve conservationists' mental health and abilities to protect nature.

Mejores condiciones de trabajo para apoyar la salud mental de los conservacionistas Resumen La conservación de la biodiversidad puede ser difícil pero gratificante y ambos aspectos pueden tener consecuencias en la salud mental de los conservacionistas. Sin embargo, sabemos poco sobre la salud mental de los conservacionistas, sus patrones y los factores de protección y riesgo asociados al lugar de trabajo. Un mayor conocimiento ayudaría a mejorar las condiciones de trabajo, pues impulsaría la satisfacción laboral, la productividad y el compromiso de los conservacionistas, mientras se reducen los costos derivados de la rotación de personal, el ausentismo y el presentismo. Encuestamos a 2,311 profesionales de la conservación de 122 países con una encuesta virtual compartida por listas de correo, redes sociales y otros medios. Les preguntamos a los profesionales sobre sus experiencias de estrés psicológico, condiciones de trabajo y características personales. Más de la mitad trabajaban y procedían de Europa y Norteamérica; la mayoría respondió en inglés, contaba con estudios universitarios y actualmente desempeña funciones académicas y profesionales. La carga de trabajo excesiva, las exigencias laborales y la inestabilidad organizacional se relacionaron con un mayor estrés, mientras la estabilidad laboral y la satisfacción con la contribución propia a la conservación se asociaron con un menor estrés. En nuestra muestra, los encuestados con baja disposición y un optimismo específico hacia la conservación, mala salud física, apoyo social limitado, las mujeres y los profesionales que inician su carrera son los que corren un mayor riesgo de sufrir estrés. Nuestros resultados señalan importantes factores de riesgo que los empresarios podrían considerar, aunque es necesario seguir investigando entre los grupos menos representados en nuestra muestra. Con base en las intervenciones de salud laboral respaldadas con pruebas, sugerimos medidas que podrían promover mejores condiciones de trabajo y, así mejorar la salud mental de los conservacionistas y su capacidad para proteger la naturaleza.

Balancing making a difference with making a living in the conservation sector.

Goals play important roles in people's lives because they focus attention, mobilize effort, and sustain motivation. Understanding conservationists' satisfaction with goal progress may provide insights into real-world environmental trends and flag risks to their well-being and motivation. We asked 2694 conservationists working globally how satisfied they were with progress toward goals important to them. We then explored how this satisfaction varied among groups, including demographic and occupational. Finally, we looked at respondents' experiences associated with goal-progress satisfaction. Many (94.0%) indicated that making a meaningful contribution to conservation was an important goal for them, and over half were satisfied or very satisfied in this area (52.5%). However, respondents were generally dissatisfied with progress on collective conservation goals (e.g., stopping species loss). Some groups were more likely to report dissatisfaction than others. For instance, those in conservation for longer tended to be less satisfied with collective goal progress (log odds -0.21, 95% credibility interval [CI] -0.32 to -0.10), but practitioners reported greater satisfaction (log odds 0.38, 95% CI 0.15-0.60). Likewise, those who were more optimistic in life (log odds 0.24, 95% CI 0.17-0.32), male (log odds 0.25, 95% CI 0.10-0.41), and working in conservation practice (log odds 0.25, 95% CI 0.08-0.43) reported greater satisfaction with individual goal progress. Free-text responses suggested widespread dissatisfaction with livelihood goals, particularly related to job security and adequate compensation. Although contributing to conservation appeared to be a source of satisfaction, slow goal progress in other areas--particularly around making a living--looked to be a source of distress and demotivation. Employers, funders, professional societies, and others should consider ways to help those in the sector make a difference while making a satisfactory living by, for example, prioritizing conservationists' well-being when allocating funding. This support could include avoiding exploitative practices, fostering supportive work environments, and celebrating positive outcomes.

El Balance entre Hacer una Diferencia y Ganarse la Vida en el Sector de la Conservación 21-323 Resumen Los objetivos juegan un papel importante en la vida de las personas porque enfocan la atención, movilizan esfuerzos y mantienen la motivación. El entendimiento de la satisfacción de los conservacionistas con el progreso de sus objetivos podría proporcionar información sobre las tendencias ambientales del mundo real y marcar los riesgos para su bienestar y motivaciones. Les preguntamos a 2694 conservacionistas trabajando alrededor del mundo cuán satisfechos están con el progreso hacia los objetivos que consideran más importantes. Después exploramos cómo esta satisfacción varió entre grupos, incluyendo grupos demográficos y laborales. Finalmente, observamos las experiencias de los respondientes asociadas con la satisfacción con el progreso de los objetivos. Muchos (94%) indicaron que contribuir significativamente a la conservación es un objetivo importante para ellos, y más de la mitad estuvieron satisfechos o muy satisfechos en este campo (52.5%). Sin embargo, los respondientes también mostraron una inconformidad generalizada con el progreso de los objetivos colectivos de conservación (p. ej.: detener la pérdida de especies). Algunos grupos tuvieron una mayor probabilidad de reportar inconformidades que otros grupos. Por ejemplo, aquellos con mayor tiempo en la conservación tendieron a estar menos satisfechos con el progreso de los objetivos colectivos (probabilidad log -0.21, 95% intervalo de credibilidad [IC] -0.32 a -0.10), pero los practicantes reportaron una mayor satisfacción (probabilidad log 0.38, 95% IC 0.15-0.60). De igual manera, quienes cuentan con mayor optimismo cotidiano (probabilidad log 0.24, 95% IC 0.17-0.32), son de sexo masculino (probabilidad log 0.25, 95% IC 0.10-0.41) y trabajan en la práctica de la conservación (probabilidad log 0.25, 95% IC 0.08-0.43) reportaron una mayor satisfacción con el progreso de los objetivos individuales. Las respuestas de texto libre sugirieron una inconformidad generalizada con los objetivos de sustento, particularmente los relacionados con la seguridad laboral y las compensaciones adecuadas. Aunque contribuir a la conservación parece ser una fuente de satisfacción, el progreso lento de los objetivos en otras áreas - particularmente las relacionadas con ganarse la vida - indicaba ser una fuente de angustia y desmotivación. Los empleadores, financiadores, las sociedades profesionales y demás deberían considerar maneras para ayudar a aquellos en el sector de la conservación a lograr una diferencia a la vez que se ganan la vida satisfactoriamente, por ejemplo, mediante la priorización del bienestar de los conservacionistas al momento de asignar financiamientos. Este apoyo podría incluir evitar prácticas explotadoras, fomentar ambientes de trabajo solidarios y celebrar los resultados positivos.

Predicting and reducing potential parasite infection between migratory livestock and resident Asiatic ibex of Pin valley, India.

Disease cross-transmission between wild and domestic ungulates can negatively impact livelihoods and wildlife conservation. In Pin valley, migratory sheep and goats share pastures seasonally with the resident Asiatic ibex (Capra sibirica), leading to potential disease cross-transmission. Focussing on gastro-intestinal nematodes (GINs) as determinants of health in ungulates, we hypothesized that infection on pastures would increase over summer from contamination by migrating livestock. Consequently, interventions in livestock that are well-timed should reduce infection pressure for ibex. Using a parasite life-cycle model, that predicts infective larval availability, we investigated GIN transmission dynamics and evaluated potential interventions. Migratory livestock were predicted to contribute most infective larvae onto shared pastures due to higher density and parasite levels, driving infections in both livestock and ibex. The model predicted a c.30-day antiparasitic intervention towards the end of the livestock's time in Pin would be most effective at reducing GINs in both hosts. Albeit with the caveats of not being able to provide evidence of interspecific parasite transmission due to the inability to identify parasite species, this case demonstrates the usefulness of our predictive model for investigating parasite transmission in landscapes where domestic and wild ungulates share pastures. Additionally, it suggests management options for further investigation.

Gut microbiota of the critically endangered Saiga antelope across two wild populations in a year without mass mortality.

The Saiga are migratory antelopes inhabiting the grasslands of Eurasia. Over the last century, Saiga have been pushed to the brink of extinction by mass mortality events and intense poaching. Yet, despite the high profile of the Saiga as an animal of conservation concern, little is known of its biology. In particular, the gut microbiota of Saiga has not been studied, despite its potential importance in health. Here, we characterise the gut microbiota of Saiga from two geographically distinct populations in Kazakhstan and compare it with that of other antelope species. We identified a consistent gut microbial diversity and composition among individuals and across two Saiga populations during a year without die-offs, with over 85% of bacterial genera being common to both populations despite vast geographic separation. We further show that the Saiga gut microbiota resembled that of five other antelopes. The putative causative agent of Saiga mass die-offs, Pasteurella multocida, was not detected in the Saiga microbiota. Our findings provide the first description of the Saiga gut microbiota, generating a baseline for future work investigating the microbiota's role in health and mass die-offs, and supporting the conservation of this critically endangered species.

Increasing risks for emerging infectious diseases within a rapidly changing High Asia.

The cold and arid mountains and plateaus of High Asia, inhabited by a relatively sparse human population, a high density of livestock, and wildlife such as the iconic snow leopard Panthera uncia, are usually considered low risk for disease outbreaks. However, based on current knowledge about drivers of disease emergence, we show that High Asia is rapidly developing conditions that favor increased emergence of infectious diseases and zoonoses. This is because of the existing prevalence of potentially serious pathogens in the system; intensifying environmental degradation; rapid changes in local ecological, socio-ecological, and socio-economic factors; and global risk intensifiers such as climate change and globalization. To better understand and manage the risks posed by diseases to humans, livestock, and wildlife, there is an urgent need for establishing a disease surveillance system and improving human and animal health care. Public health must be integrated with conservation programs, more ecologically sustainable development efforts and long-term disease surveillance.

Predicting Parasite Dynamics in Mixed-Use Trans-Himalayan Pastures to Underpin Management of Cross-Transmission Between Livestock and Bharal.

The complexities of multi-use landscapes require sophisticated approaches to addressing disease transmission risks. We explored gastro-intestinal nematode (GINs) infections in the North India Trans-Himalayas through a socio-ecological lens, integrating parasite transmission modelling with field surveys and local knowledge, and evaluated the likely effectiveness of potential interventions. Bharal (blue sheep; Pseudois nayaur), a native wild herbivore, and livestock share pasture year-round and livestock commonly show signs of GINs infection. While both wild and domestic ungulates had GINs infections, egg counts indicated significantly higher parasite burdens in bharal than livestock. However, due to higher livestock densities, they contributed more to the total count of eggs and infective larvae on pasture. Herders also reported health issues in their sheep and goats consistent with parasite infections. Model simulations suggested that pasture infectivity in this system is governed by historical pasture use and gradually accumulated larval development during the summer, with no distinct short-term flashpoints for transmission. The most effective intervention was consequently predicted to be early-season parasite suppression in livestock using temperature in spring as a cue. A 1-month pause in egg output from livestock could lead to a reduction in total annual availability of infective larvae on pasture of 76%, potentially benefitting the health of both livestock and bharal. Modelling suggested that climate change over the past 33 years has led to no overall change in GINs transmission potential, but an increase in the relative influence of temperature over precipitation in driving pasture infectivity. Our study provides a transferable multi-pronged approach to investigating disease transmission, in order to support herders' livelihoods and conserve wild ungulates.
