“…The humanrelated factor was the only macroecological variable included in the best models for scavenger richness. All of these factors are known to affect vertebrates (e.g., Tucker et al, 2018), to predict extinction risk (Di Marco, Venter, Possingham, & Watson, 2018), and to negatively affect particular scavenger species, at least at the local scale (e.g., Bogoni et al, 2016;Lambertucci et al, 2009). HF combines information on human population density, harvest, livestock, land use, land change, and human accessibility.…”

“…For sample size, we also show the regression line for the relationships. This may have several consequences, such as increasing the risk of pests and infectious disease transmission (Buechley & Şekercioğlu, 2016;Ogada et al, 2012) or slowing down the cycling of nutrients (Moore et al, 2004). In areas where the most endangered species in the scavenger community (i.e., obligate scavengers and top predators) have become rare or absent, carrion may remain in the field for longer periods of time, leading to an increase in generalist scavengers that are less efficient at removing carcasses (Mateo-Tomás et al, 2017;Morales-Reyes et al, 2017).…”

Understanding the distribution of biodiversity across the Earth is one of the most challenging questions in biology. Much research has been directed at explaining the species latitudinal pattern showing that communities are richer in tropical areas; however, despite decades of research, a general consensus has not yet emerged. In addition, global biodiversity patterns are being rapidly altered by human activities. Here, we aim to describe large‐scale patterns of species richness and diversity in terrestrial vertebrate scavenger (carrion‐consuming) assemblages, which provide key ecosystem functions and services. We used a worldwide dataset comprising 43 sites, where vertebrate scavenger assemblages were identified using 2,485 carcasses monitored between 1991 and 2018. First, we evaluated how scavenger richness (number of species) and diversity (Shannon diversity index) varied among seasons (cold vs. warm, wet vs. dry). Then, we studied the potential effects of human impact and a set of macroecological variables related to climatic conditions on the scavenger assemblages. Vertebrate scavenger richness ranged from species‐poor to species rich assemblages (4–30 species). Both scavenger richness and diversity also showed some seasonal variation. However, in general, climatic variables did not drive latitudinal patterns, as scavenger richness and diversity were not affected by temperature or rainfall. Rainfall seasonality slightly increased the number of species in the community, but its effect was weak. Instead, the human impact index included in our study was the main predictor of scavenger richness. Scavenger assemblages in highly human‐impacted areas sustained the smallest number of scavenger species, suggesting human activity may be overriding other macroecological processes in shaping scavenger communities. Our results highlight the effect of human impact at a global scale. As species‐rich assemblages tend to be more functional, we warn about possible reductions in ecosystem functions and the services provided by scavengers in human‐dominated landscapes in the Anthropocene.

“…The Brazilian part of the Atlantic forest nowadays covers~12% of the original area, distributed in 245 173 forest fragments (Ribeiro et al, 2009). This forest patch suffered and continues suffering from illegal palm harvesting (Galetti & Fernandez, 1998), hunting , humanmade infrastructure (pipeline, roads) and human encroachment that negatively affect animal movement and increase mortality (Miotto et al, 2012;Bogoni et al, 2016). This single patch contains~1 109 546 ha of continuous forests, which represents 7% of what remains (Ribeiro et al, 2009).…”

Defaunation and biomass collapse of mammals in the largest Atlantic forest remnant

Large continuous rainforests are the main hope for sustaining the population of large-bodied vertebrates that cannot cope with fragmentation or unsustainable hunting. The Brazilian Atlantic forest is considered a biodiversity hotspot and although highly fragmented, it still contains large forest patches that may be important for the conservation of mammals that require large areas. Here, we estimated species richness, density and biomass of medium- and large-sized mammals along the largest remnant of the Atlantic rainforest, Brazil (the Serra do Mar bioregion), an estimated area of 8000 km2. We recorded 44 species based on 4090 km of diurnal line transects and camera traps, animal tracks and interviews in 11 continental regions and two large land-bridge islands. We found high levels of similarity in mammalian composition between pairs of sites in the continental forest sites (0.84-1), but much lower similarity between pairs from the continental forest sites and the two large land-bridge islands (0.29-0.74) indicating potential local extinctions or poor dispersal of continental mammals to these islands. In addition, we found that the density and biomass varied 16- and 70-fold among sites, respectively. Mammalian biomass declined by up to 98% in intensively hunted sites and was 53-fold lower than in other Neotropical non-fragmented forests. Although this large forest remnant is able to maintain a high diversity of medium- and large-bodied mammal species, their low density and biomass may affect the long-term persistence of these populations and the ecosystem services they provide

“…Outra floresta tropical no continente Sul americano, a majestosa Mata Atlântica é apontada como uma área prioritária para a conservação da biodiversidade. Essa ecorregião contém uma riqueza de mais de 300 espécies de mamíferos e está fortemente ameaçada por uma série de fatores (e.g., fragmentação e perda de hábitat, introdução de espécies exóticas e defaunação) (Paglia & Pinto, 2010;Bogoni et al, 2016 a).…”

Medium-to large-bodied mammalian fauna of Parque Ecológico Rancho dos Bugres, Southern Brazil. Mammalian fauna is under several threat, mainly in Atlantic Forest of South America. Atlantic Forest is an ecorregion strongly endangered by habitat loss and fragmentation, processes that influencing directly the ecosystems functioning. We developed a mammalian inventory in a forest remnant in southern of Santa Catarina, Brazil, aiming to know the medium-to large-bodied mammalian composition and diversity. The study was carried in three transects within Parque Ecológico Rancho dos Bugres (PERB; 28º29'S and 49º15'W) through camera-traps, resulting in a total effort of 630 traps/day. We obtained 106 independent records of nine mammalian species, within the orders Carnivora, Cingulata and Rodentia. The results of our study can increase the knowledge about the mammalian diversity and distribution in the subtropical Atlantic Forest. Moreover, can be generated subsidies for the implementation of conservation strategies on mammalian fauna and contributing to filling part of the gap in the knowledge of distribution of medium-to large-bodied mammals in a region poorly studied.Resumo: A fauna de mamíferos está sob ameaça, principalmente na Floresta Atlântica da América do Sul.Essa é uma ecorregião fortemente ameaçada pela perda e fragmentação do hábitat, processos que influenciam diretamente o funcionamento dos ecossistemas. Desenvolvemos um inventário de mamíferos em um remanescente florestal no sul de Santa Catarina, Brasil, objetivando conhecer a composição e a diversidade de mamíferos de médio e grande porte. O estudo foi realizado em três transectos no Parque Ecológico Rancho dos Bugres (PERB, 28º29'S e 49º15'W) através de armadilhas fotográficas, resultando em um esforço total de 630 armadilhas/dia. Obtivemos 106 registros independentes de nove espécies de mamíferos, das ordens Carnivora, Cingulata e Rodentia. Os resultados do nosso estudo aumentam o conhecimento sobre a diversidade e distribuição de mamíferos na Mata Atlântica subtropical. Além disso, podem ser utilizados para gerar subsídios para a implementação de estratégias de conservação na fauna de mamíferos, contribuindo para preencher parte da lacuna no conhecimento da distribuição de mamíferos de médio e grande porte em uma região pouco estudada.
