Phylogenetically diverse diets favor more complex venoms in North American pitvipers.

The role of natural selection in the evolution of trait complexity can be characterized by testing hypothesized links between complex forms and their functions across species. Predatory venoms are composed of multiple proteins that collectively function to incapacitate prey. Venom complexity fluctuates over evolutionary timescales, with apparent increases and decreases in complexity, and yet the causes of this variation are unclear. We tested alternative hypotheses linking venom complexity and ecological sources of selection from diet in the largest clade of front-fanged venomous snakes in North America: the rattlesnakes, copperheads, cantils, and cottonmouths. We generated independent transcriptomic and proteomic measures of venom complexity and collated several natural history studies to quantify dietary variation. We then constructed genome-scale phylogenies for these snakes for comparative analyses. Strikingly, prey phylogenetic diversity was more strongly correlated to venom complexity than was overall prey species diversity, specifically implicating prey species' divergence, rather than the number of lineages alone, in the evolution of complexity. Prey phylogenetic diversity further predicted transcriptomic complexity of three of the four largest gene families in viper venom, showing that complexity evolution is a concerted response among many independent gene families. We suggest that the phylogenetic diversity of prey measures functionally relevant divergence in the targets of venom, a claim supported by sequence diversity in the coagulation cascade targets of venom. Our results support the general concept that the diversity of species in an ecological community is more important than their overall number in determining evolutionary patterns in predator trait complexity.

Ancestrally Reconstructed von Willebrand Factor Reveals Evidence for Trench Warfare Coevolution between Opossums and Pit Vipers.

Opossums in the tribe Didelphini are resistant to pit viper venoms and are hypothesized to be coevolving with venomous snakes. Specifically, a protein involved in blood clotting (von Willebrand factor [vWF] which is targeted by snake venom C-type lectins [CTLs]) has been found to undergo rapid adaptive evolution in Didelphini. Several unique amino acid changes in vWF could explain their resistance; however, experimental evidence that these changes disrupt binding to venom CTLs was lacking. Furthermore, without explicit testing of ancestral phenotypes to reveal the mode of evolution, the assertion that this system represents an example of coevolution rather than noncoevolutionary adaptation remains unsupported. Using expressed vWF proteins and purified venom CTLs, we quantified binding affinity for vWF proteins from all resistant taxa, their venom-sensitive relatives, and their ancestors. We show that CTL-resistant vWF is present in opossums outside clade Didelphini and likely across a wider swath of opossums (family Didelphidae) than previously thought. Ancestral reconstruction and in vitro testing of vWF phenotypes in a clade of rapidly evolving opossums reveal a pattern consistent with trench warfare coevolution between opossums and their venomous snake prey.

Bacterial pathogens' screening in Brazilian chigger mites (Trombidiformes: Trombiculidae), with the first report of 'Candidatus Rickettsia colombianensi'-like in avian-associated chiggers.

Chiggers are larval ectoparasites of the Trombiculidae that can transmit pathogens to their hosts. In this study, chiggers collected from birds in Brazil were morphologically identified as Blankaartia sinnamaryi, Eutrombicula batatas, Eutrombicula daemoni, Eutrombicula goeldii, Eutrombicula tinami, and Parasecia gilbertoi. For these specimens, a beginning attempt at molecular identification were also provided, as well as, were genetically screened to detect bacterial pathogens. The species B. sinnamaryi and E. tinami were positive for Rickettsia felis-like and 'Candidatus Rickettsia colombianensi'-like, respectively. For the other agents (Anaplasmataceae, Borrelia spp. and Orientia tsutsugamushi), the tests were negative. This is the first report of 'Ca. R. colombianensi'-like and the second record of R. felis-like in chigger collected on birds from Brazil.

Nature Photographs as Complementary Care in Chemotherapy: A Randomized Clinical Trial.

The incidence of cancer cases is increasing worldwide, and chemotherapy is often necessary as part of the treatment for many of these cases. Nature-based interventions have been shown to offer potential benefits for human well-being. OBJECTIVE: This study aims to investigate the outcome of nature images on clinical symptom management related to chemotherapy. METHODS: A randomized clinical trial was conducted in an outpatient cancer unit of a private hospital in Brazil, with 173 participants over the age of 18 who were undergoing chemotherapy and had signed an informed consent form. The intervention consisted of the presentation of a 12-min video featuring nature images categorized under the themes of Tranquility, Beauty, Emotions Up, or Miscellany. Images were sourced from the e-Nature Positive Emotions Photography Database (e-NatPOEM), a publicly available collection of affectively rated images. Sociodemographic and clinical data, as well as the participants' connection to nature, were investigated. The Positive Affect/Negative Affect Scale (PANAS) and the Edmonton Symptom Assessment System (ESAS) were applied pre- and post-intervention. RESULTS: Data showed very strong evidence of a reduction in negative affect for the intervention group (p < 0.001) and moderate evidence for the control group (p = 0.034). There was also a significant reduction in the intervention group for pain (p < 0.001), tiredness (p = 0.002), sadness (p < 0.001), anxiety (p < 0.001), and appetite (p = 0.001). The Beauty video had the best performance, while the Tranquility video showed no significant improvement in any of the symptoms evaluated. These findings suggest that images of nature may be a valuable tool to help control clinical and psychological symptoms in cancer patients undergoing chemotherapy.

A time with e-Natureza (e-Nature): a model of nature-based health interventions as a complex adaptive system.

Discussions surrounding the positive impacts of nature on human health and strategies to enhance our connection with the natural world have been ongoing. However, a limited number of theoretical models are available to guide research and practice in this area. Therefore, there is a pressing need for a systematic framework that outlines clear steps for conducting research implementing nature-based interventions. In this study, we investigate the relationship between health and nature through the lens of Complex Adaptive Systems. This approach involves examining the dynamic interactions between multiple interconnected elements to understand the complex emergent behaviors that arise from such relationships. Our model is designed to support nature-based interventions, considering the essential interdependence between humans and nature. This perspective aims to improve both human health and biodiversity conservation in a mutually beneficial manner. The underlying interactions that drive nature-based health interventions are thoroughly explored, leading us to propose a novel intervention model named "A time with e-Natureza" (e-Nature). This model encompasses four types of experiences, drawing from scientific literature and insights from authors engaged in an interdisciplinary research group: (1) Aesthetic and emotional experience; (2) Multisensory integration experience; (3) Knowledge experience; and (4) Engagement experience. Each experience within the model targets affective, cognitive, and behavioral aspects, with a specific focus on fostering a deeper connection with nature. Distinct activities are incorporated within each experience to promote successful outcomes. The model is grounded in existing theories that address the human-nature relationship and is informed by Nursing theories that support health promotion interventions. By presenting this new model, our aim is to contribute to the effective implementation of nature-based interventions that not only enhance human well-being but also support the conservation of nature. This integrated approach recognizes the mutual benefits of human-nature interaction and offers valuable insights for future research and practical applications in the fields of nature and health.

A novel method for extraction and quantification of feather triiodothyronine (T3) and application to ecotoxicology of Purple Martin (Progne subis).

Seventy-three percent of aerial insectivore species of birds breeding in North America have declined in the past five years. This decline is even greater in migratory insectivorous species, which face stressors in both their breeding and non-breeding ranges. The Purple Martin (Progne subis) is an aerial insectivore swallow that overwinters in South America and migrates to North America to breed. Purple Martin populations have declined by an estimated 25% since 1966. The eastern subspecies (P. subis subis) has declined the most and overwinters in the Amazon Basin, a region rich in environmental mercury (Hg) contamination. Previous studies reported elevated levels of Hg in feathers of this subspecies, which correlated negatively with body mass and fat reserves. Given the propensity of Hg to disrupt the endocrine system, and the role of thyroid hormones in regulating fat metabolism, this study quantifies concentrations of Hg and the thyroid hormone triiodothyronine (T3) in the feathers of P. subis subis. To our knowledge, this is the first study to extract and quantify T3 in feathers; thus, we developed, tested, and optimized a method for extracting T3 from feather tissue and validated an enzyme immunoassay (EIA) to quantify T3 in Purple Martin feathers. The developed method yielded acceptable results for both parallelism and accuracy. The observed T3 concentrations were statistically modeled along with total Hg (THg) concentrations, but these variables were not significantly correlated. This suggests that the observed variation in THg concentration may be insufficient to cause a discernible change in T3 concentration. Furthermore, the observed effect of breeding location on feather T3 concentration might have obscured any effect of Hg.

Genetic diversity of adenovirus in neotropical bats from Brazil.

Bats can harbor a diversity of viruses, such as adenovirus. Ten different species of bat adenoviruses (BtAdV A to J) have been previous described worlwide. In Brazil, BtAdV was described in three species of phyllostomid species: Artibeus lituratus, Desmodus rotundus, and Sturnira lilium. There are around 180 bat species in Brazil, with 67% inhabiting the Atlantic Forest, with few information about the circulation of BtAdV in this biome. We aimed to describe the molecular detection and the phylogenetic characterization and suggest a classification of BtAdVs circulating in bats from the Brazilian Atlantic Forest. We collected 382 oral and rectal swabs from 208 bats between 2014-2015 and 2020-2021 from São Paulo, Pernambuco, and Santa Catarina Brazilian states. The adenovirus detection was done by a nested PCR targeting the DNA polymerase gene, and all positive samples were sequenced by the Sanger method. The phylogenetic analyses were based on the amino acid sequences using the MEGA 7 and BEAST software. We obtained 16 positive animals (detection rate 7.7%) belonging to seven bat species: Artibeus lituratus, Carollia perspicillata, Sturnira lilium, Molossus molossus, and the first record of Phyllostomus discolor, Eptesicus diminutus, and Myotis riparius. The phylogenetic analysis based on partial amino acid sequences showed that all obtained AdV sequences belong to the Mastadenovirus genus. We observed a high genetic diversity of BtAdV and identified eleven potential BtAdV species circulating in Brazil (BtAdV K to U). Our results contribute to the epidemiological surveillance of adenovirus, increasing the knowledge about the viral diversity and the distribution of AdV in bats from the Atlantic Forest.

Interrelationships among feather mercury content, body condition and feather corticosterone in a Neotropical migratory bird, the Purple Martin (Progne subis subis).

Purple Martins (Progne subis) are migratory birds that breed in North America and overwinter and complete their molt in South America. Many of the breeding populations are declining. The eastern North American subspecies of Purple Martin (P. subis subis) comprises >90% of all Purple Martins. This subspecies overwinters and molts in the Amazon Basin, a region that is high in mercury (Hg) contamination, which raises the possibility that observed declines in Purple Martins could be linked to Hg exposure. Exposure to Hg results in numerous and systemic negative health outcomes, including endocrine disruption. Corticosterone (CORT) is a primary modulator of the stress and metabolic axes of vertebrates; thus, it is important in meeting metabolic and other challenges of migration. Because feathers accumulate Hg and hormones while growing, quantification of Hg and CORT in feathers provides an opportunity to retrospectively assess Hg exposure and adrenal activity of birds using minimally invasive methods. We evaluated interrelationships among concentrations of total Hg (THg) and CORT in feathers that grew in the Amazon Basin and body condition (mass, fat score) of these birds in North America. Concentrations of THg in Purple Martin feathers ranged from 1.103 to 8.740 µg/g dw, levels associated with negative physiological impacts in other avian species. Concentrations of CORT did not correlate with THg concentration at the time of feather growth. However, we found evidence that THg concentration may negatively impact the ability of Purple Martins to accumulate fat, which could impair migratory performance and survivorship due to the high energy requirements of migration. This finding suggests potential carryover effects of Hg contamination at the wintering grounds in the Amazon to the summer breeding grounds in North America.

High genetic diversity of alphacoronaviruses in bat species (Mammalia: Chiroptera) from the Atlantic Forest in Brazil.

Bat coronaviruses (Bat-CoVs) represent around 35% of all virus genomes described in bats. Brazil has one of the highest mammal species diversity, with 181 species of bats described so far. However, few Bat-CoV surveillance programmes were carried out in the country. Thus, our aim was to jevaluate the Bat-CoV diversity in the Atlantic Forest, the second biome with the highest number of bat species in Brazil. We analysed 456 oral and rectal swabs and 22 tissue samples from Atlantic Forest bats, detecting Alphacoronavirus in 44 swab samples (9.6%) targeting the RdRp gene from seven different bat species, three of which have never been described as Bat-CoV hosts. Phylogenetic analysis of the amino acid (aa) sequences coding the RdRp gene grouped the sequences obtained in our study with Bat-CoV previously detected in identical or congeneric bat species, belonging to four subgenera, with high aa identity (over 90%). The RdRp gene was also detected in three tissue samples from Diphylla ecaudata and Sturnira lilium, and the partial S gene was successfully sequenced in five tissues and swab samples of D. ecaudata. The phylogenetic analysis based on the partial S gene obtained here grouped the sequence of D. ecaudata with CoV from Desmodus rotundus previously detected in Peru and Brazil, belonging to the Amalacovirus subgenus, with aa identity ranging from 73.6% to 88.8%. Our data reinforce the wide distribution of Coronaviruses in bats from Brazil and the novelty of three bats species as Bat-CoV hosts and the co-circulation of four Alphacoronavirus subgenera in Brazil.

e-Nature Positive Emotions Photography Database (e-NatPOEM): affectively rated nature images promoting positive emotions.

Affectively rated image databases have their main application in studies that require inducing distinct stimuli on subjects. Widespread databases are designed to cover a broad range of stimuli, from negative to positive (valence), and relaxed to excited (arousal). The availability of narrow domain databases, designed to cover and thoroughly analyze a few categories of images that induce a particular stimulus, is limited. We present a narrow domain affective database with positive images, named e-Nature Positive Emotions Photography Database (e-NatPOEM), consisting of 433 high-quality images produced by professional and amateur photographers. A total of 739 participants evaluated them using a web-based tool to input valence-arousal values and a single word describing the evoked feeling. Ratings per image ranged from 36 to 108, median: 57; first/third quartiles: 56/59. 84% of the images presented valence > middle of the scale and arousal < middle of the scale. Words describing the images were classified into semantical groups, being predominant: Peace/tranquility (39% of all words), Beauty (23%), and Positive states (15%). e-NatPOEM is free and publicly available, it is a valid resource for affective research, and presents the potential for clinical use to assist positive emotions promotion.

A Revision of Parasecia (Trombidiformes: Trombiculidae) With a Description of a New Species, a New Genus and a Key to Species.

Chiggers of the genus Parasecia Loomis parasitize birds, mammals, and reptiles in the Nearctic and Neotropical regions. In the present review, we examined 18 species previously included in the genus, 15 of them being retained in the genus Parasecia, one genus is created, Nahuacarus bulbocalcarn. gen. (Trombidiformes: Trombiculidae), and new combinations are proposed for two species: Lorillatum lasiurusn. comb. and Lorillatum orphanan. comb. (Trombidiformes: Trombiculidae). In addition, Parasecia kansasensis (Loomis) (Trombidiformes: Trombiculidae) is synonymized with Parasecia gurneyi (Ewing) (Trombidiformes: Trombiculidae), Parasecia gilbetoin. sp. (Trombidiformes: Trombiculidae) is described and new locality and host records are added for Parasecia chara (Wharton), Parasecia longicalcar (Brennan and Jones), Parasecia manueli (Brennan and Jones), and Parasecia thalurania (Brennan) (Trombidiformes: Trombiculidae).

Resistance of South American opossums to vWF-binding venom C-type lectins.

Opossums in the clade Didelphini are well known to be resistant to snake venom due to endogenous circulating inhibitors which target metalloproteinases and phospholipases. However, the mechanisms through which these opossums cope with a variety of other damaging venom proteins are unknown. A protein involved in blood clotting (von Willebrand Factor) has been found to have undergone rapid adaptive evolution in venom-resistant opossums. This protein is a known target for a subset of snake venom C-type lectins (CTLs), which bind it and then induce it to bind platelets, causing hemostatic disruption. Several amino acid changes in vWF unique to these opossums could explain their resistance; however, experimental evidence that these changes disrupt venom CTL binding was lacking. We used platelet aggregation assays to quantify resistance to a venom-induced platelet response in two species of venom-resistant opossums (Didelphis virginiana, Didelphis aurita), and one venom-sensitive opossum (Monodelphis domestica). We found that all three species have lost nearly all their aggregation response to the venom CTLs tested. Using washed platelet assays we showed that this loss of aggregation response is not due to inhibitors in the plasma, but rather to the failure of either vWF or platelets (or both) to respond to venom CTLs. These results demonstrate the potential adaptive function of a trait previously shown to be evolving under positive selection. Surprisingly, these findings also expand the list of potentially venom tolerant species to include Monodelphis domestica and suggest that an ecological relationship between opossums and vipers may be a broader driver of adaptive evolution across South American marsupials than previously thought.

Contribution to the knowledge about mammal collections in Brazil

We provide a brief introduction on the importance and use of scientific collections and a general overview of the articles that are part of the special issue of the Brazilian Journal of Mammalogy on Brazilian mammal collections. The 19 articles that comprise this issue refer to collections distributed across eight Brazilian states. Most of the collections hold specimens of living mammals, and two of them are paleontological collections. Two articles address specific orders of mammals, while the rest present data for all the orders. We hope that this issue represents a significant contribution to efforts to preserve Brazilian scientific collections, providing a more comprehensive view of their importance and the current and potential use of the specimens preserved therein.

Apresentamos uma breve introdução sobre a importância e uso de coleções científicas e um panorama geral dos artigos que fazem parte do número especial do Brazilian Journal of Mammalogy sobre coleções brasileiras de mamíferos. Os 19 artigos abrangem coleções distribuídas em oito estados da federação. Em sua maioria tratam de mamíferos viventes, sendo dois referentes a coleções paleontológicas. Dois artigos abordam ordens específicas de mamíferos e os demais apresentam dados para todas as ordens. Esperamos que este número represente uma contribuição significativa aos esforços para preservar as coleções científicas nacionais, fornecendo uma visão mais abrangente acerca das coleções e do uso atual e potencial dos espécimes nelas preservados.

Concrete survivors: the herpetofauna of an urban green area over 100 years of increasing urbanization / Sobreviventes do concreto: a herpetofauna de uma áreaverde urbana ao longo de 100 anos de urbanização

Abstract Low biodiversity in urban areas is associated with habitat loss. However, the effects of urbanization on biodiversity should also consider the historical background of land-use, explored herein. Our goal was to evaluate changes in the assemblage of reptiles in an urban habitat over 100 years, aiming to identify which ecological attributes allowed the persistence of species that can be found in the area today. We accessed historical records in scientific collections and carried out fieldwork to access reptile assemblage in an urban green area, in São Paulo, Brazil. Considering land-use changes in the area, we defined three-time intervals between 1901 and 2020. We established species richness for each time interval, categorizing them into three ecological attributes: habitat preference, substrate use, and food habits. We recorded 27 reptile species from 1901 until 2020, 14 resulting from historical data, eight from both historical and fieldwork, and five species exclusively in fieldwork. Amphibians were also sampled during fieldwork, but not used in historical comparison. Reptile's species richness decreased 59% regardless of ecological attributes, and snakes were the group with most species' loss. Fossorial reptiles were the least affected group. We concluded that habitat loss culminated in a species richness decline, and the reptiles that remain until today were likely present since the fragment isolation. Ecological attributes of the remaining taxa include species that use terrestrial substrates and feed on prey commonly found in urban environments.

Resumo A baixa biodiversidade em áreas urbanas está associada à perda de habitat. No entanto, os efeitos da urbanização sobre a biodiversidade também devem considerar o histórico de uso da terra, explorado aqui. Nosso objetivo foi avaliar as mudanças na comunidade de répteis em um habitat urbano ao longo de 100 anos, visando identificar quais atributos ecológicos permitiram a persistência de espécies que podem ser encontradas na área hoje. Acessamos registros históricos em coleções científicas e realizamos trabalho de campo para levantar as espécies de répteis em uma área verde urbana, em São Paulo, Brasil. Considerando as mudanças de uso da terra na área amostrada, definimos três intervalos de tempo entre 1901 e 2020. Estabelecemos a riqueza de espécies para cada intervalo de tempo, categorizando-as em três atributos ecológicos: preferência de habitat, uso de substrato e hábitos alimentares. Registramos 27 espécies de répteis de 1901 até 2020, sendo 14 resultantes de dados históricos, oito de dados históricos e de campo e cinco espécies amostradas exclusivamente de campo. Anfíbios também foram amostrados durante o trabalho de campo, mas não foram usados na comparação histórica. A riqueza de espécies de répteis diminuiu 59% independentemente dos atributos ecológicos, e serpente foi o grupo com maior perda de espécies. Os répteis fossoriais foram o grupo menos afetado. Concluímos que a perda de habitat culminou em um declínio da riqueza de espécies, e os répteis que permanecem até hoje provavelmente estavam presentes desde o isolamento do fragmento. Os atributos ecológicos dos táxons remanescentes incluem espécies que utilizam substratos terrestres e se alimentam de presas comumente encontradas em ambientes urbanos.

Taxonomic revision and additional comments of some bats (Mammalia, Chiroptera) reported from Bolivia, with an updated checklist based on voucher material with verified identities

We review the taxonomic identities of museum specimens of three bat species previously reported from Bolivia. We comment on some erroneously reported taxa, or taxa either not represented by voucher materials or based on insufficient data (including acoustic detections) to verify their taxonomic affinities. As result of this review, the list of bat species known to occur in Bolivia is updated to eight families and 133 species, unlike the nine families and 146 species of previous lists. Some recommendations for future research and a brief historical revision of bat inventories in the country are included.

Peregrine falcon falco peregrinus in Brazil: natural history through the lens of citizen science

Brazil is an important wintering area for Falco peregrinus, specifically for the subspecies F. p. tundrius and F. p anatum. Using data from WikiAves, we analyzed and discussed aspects of the species natural history, including migratory behavior, geographical distribution, diet, and ecological interactions. Peregrine Falcons were recorded in the country from October until April. Our data suggest that adults can arrive up to a month earlier than juveniles. Individuals have been recorded in all 26 states and there was no significant difference in their geographical distribution in relation to subspecies or age, but there is an apparent lack of records in the Center of the country. Our results showed that in Brazil peregrines prey mainly on Columbiformes and Charadriiformes. Some individuals share the same perch and engage on agonistic interactions with other bird species, usually mobbing or kleptoparasitism.

O Brasil é uma importante área de invernada para Falco peregrinus, especificamente para as subespécies F. p. tundrius e F. p. anatum. Utilizando dados provenientes do WikiAves, nós analisamos e discutimos aspectos da história natural da espécie, incluindo o comportamento migratório, distribuição geográfica, dieta e interações ecológicas. Os falcões-peregrinos podem ser avistados no país entre outubro e abril. Nossos dados sugerem que adultos chegam até um mês antes dos juvenis. Indivíduos foram registrados em todos os 26 estados e não existe nenhuma diferença significativa na distribuição geográfica devido à subespécie ou faixa etária, mas existe uma aparente escassez na região Centro Oeste. Nossos dados apontam ainda que no Brasil os falcões-peregrinos se alimentam majoritariamente de Columbiformes e Charadriiformes. Alguns indivíduos dividem o mesmo poleiro, registramos também a ocorrência de interações agonísticas com outras espécies, geralmente tumulto ou cleptoparasitismo.

Butterflies (Lepidoptera: Papilionoidea) of the urban park of Instituto Butantan, São Paulo, Southeastern Brazil

Green areas in urban landscapes are under strong anthropogenic pressure, and, at the same time are fundamental to maintaining biodiversity, as they provide resources for many animal and plant species. Knowing these species is fundamental for its maintenance and conservation, and inventories are extremely important for monitoring fauna and conserving it. Therefore, the goal of this research is to inventory the butterflies species in the park of the Instituto Butantan (Ibu), located in an urban area in the city of São Paulo, southeast Brazil. The surveys of butterflies were conducted through visual censuses from August 2017 to July 2019 and recorded a total of 324 butterfly species. The most speciose family was Hesperiidae, followed by Nymphalidae, Lycaenidae, Pieridae, Riodinidae, and Papilionidae. Among the sampled species, there is Euselasia zara which is a new record for the state of São Paulo. Neither the species accumulation nor the richness estimator curves tended to reach an asymptote, suggesting that additional butterflies’ species will be recorded with more sampling effort on the site. Even with a flora composed mainly of exotic and ornamental plants, the park of Instituto Butantan exhibits a very rich butterfly community. This community exhibits a pattern of seasonally variation, with the peak of species richness related to the rainy season. When compared with Cidade Universitária Armando de Salles Oliveira (USP), another nearby urban green area, which is larger, more heterogeneous and sampled over a longer period, it is possible to notice that the Ibu butterfly community is a subsample of this larger one. These results highlight the potential that urban parks have for the maintenance and conservation of butterfly species.
