Roadkill is widely recognized as one of the primary negative effects roads on many wildlife species and also has socioeconomic impacts when they result in accidents. A comprehensive dataset roadkill locations essential to evaluate factors contributing risk enhance our comprehension its impact populations dimensions. We undertook a compilation records, encompassing both published unpublished data gathered from road surveys or opportunistic sources. GLOBAL ROADKILL DATA includes 208,570...
Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, emerging infectious diseases. There are 26 primate species the Atlantic Forests of South America, 19 them endemic. We compiled a dataset 5,472 georeferenced locations native 1 introduced species, as hybrids genera Callithrix Alouatta. The includes 700 communities, 8,121 single occurrences 714 estimates population sizes, covering most natural forest types tropical...
Habitat fragmentation reduces biodiversity and affects ecological processes that are fundamental for maintaining ecosystem services. We investigated how landscape structure—percent forest cover, patch density, percent cover by edge, perimeter-area ratio, spatial heterogeneity—affects the diversity of mammalian carnivores at multiple extents within 22 Atlantic Forest landscapes. hypothesized 1) species richness is positively related to cover; 2) occurrence will vary according its sensitivity...
Abstract Our understanding of mammal ecology has always been hindered by the difficulties observing species in closed tropical forests. Camera trapping become a major advance for monitoring terrestrial mammals biodiversity rich ecosystems. Here we compiled one largest datasets inventories communities Neotropical region based on camera studies. The dataset comprises 170 surveys medium to large using traps conducted 144 areas 74 studies, covering six vegetation types and subtropical Atlantic...
Abstract Defaunation is a key ecological issue that has only recently been given sufficient attention. As predicted, evidence so far indicates loss of larger species followed by medium-sized species, leading to cascading effects propagate throughout entire communities and ecosystems. The Atlantic Forest among the most important global biodiversity hotspots. These regions have historically impacted habitat fragmentation, resulting in landscape changes negative impacts upon animal communities....
Abstract Mortality from collision with vehicles is the most visible impact of road traffic on wildlife. due to roads (hereafter road‐kill) can affect dynamic populations many species and can, therefore, increase risk local decline or extinction. This especially true in Brazil, where plans for network upgrading expansion overlaps biodiversity hotspot areas, which are high importance global conservation. Researchers, conservationists planners face challenge define a national strategy...
Abstract The jaguarundi Puma yagouaroundi is a small Neotropical cat that presents two main coloration phenotypes (grey/dark vs. reddish). Although these coat colour variants have been known for decades, and historically speculated to be associated with different habitats, their exact geographical distribution has never mapped. Moreover, association habitats so far not tested statistically, ecological relevance respect varying environmental features remains unknown. Based on 566 location...
Measures of traits are the basis functional biological diversity. Numerous works consider mean species-level measures while ignoring individual variance within species. However, there is a large amount variation species and it increasingly apparent that important to trait not only between species, but also Mammals an interesting group for investigating trait-based approaches because they play diverse ecological functions (e.g., pollination, seed dispersal, predation, grazing) correlated with...
Biodiversity inventories contain important information about species richness, community structure, and composition, are the first step in developing any conservation mitigation strategies. The Atlantic Forest of South America is home to around 334 small-, medium-, large-sized mammals, currently restricted less than 12% its original cover. Here, we present ATLANTIC MAMMALS, an open data set on medium- mammal assemblages Brazil, Paraguay, Argentina. A total 129 studies were compiled,...
Chiroptera é um dos grupos mais diversos de mamíferos no mundo, entretanto, várias áreas permanecem pouco amostradas. Isto também observado na região oeste do estado Santa Catarina, Sul Brasil, onde se situa a bacia rio Chapecó. No presente estudo foram analisados 267 exemplares depositados Coleção Científica da Universidade Regional Blumenau, coletados durante os estudos ambientais em três usinas hidrelétricas nessa bacia, que abrange o ecótono entre Floresta Estacional e Ombrófila Mista,...
A fusão de dentes é uma anomalia rara, caracterizada pela união dois adjacentes. Um espécime Monodelphis domestica proveniente do Boqueirão da Onça, estado Bahia, apresenta o terceiro e quarto molares superiores esquerdos fusionados através das plataformas estilares raízes vestibulares dos dentes. Aparentemente, esse primeiro caso coroa registrado em marsupiais. Causas ainda são mal compreendidas. ação forças que aproximem os desenvolvimento tem sido elencada como possibilidades para...
ABSTRACT Motivation Here, we make available a second version of the BioTIME database, which compiles records abundance estimates for species in sample events ecological assemblages through time. The updated expands 1.0 database by doubling number studies and includes substantial additional curation to taxonomic accuracy records, as well metadata. Moreover, now provide an R package (BioTIMEr) facilitate use database. Main Types Variables Included is composed one main data table containing 11...
O Parque Estadual da Serra do Tabuleiro, situado no centro-leste Estado de Santa Catarina, sul Brasil, possui 85.000ha e abrange grande diversidade ambientes (floresta ombrófila densa, incluindo manguezais restingas, floresta mista estepe ombrófila). De 1991 a 2010 foram realizados 22 estudos sobre sua mastofauna, abrangendo os métodos captura com armadilhas arame, interceptação queda, caixas nidificação, redes-de-neblina, fotográficas, observação direta vestígios. Foram registradas 75...
O gênero Cavia inclui quatro espécies no Brasil, C.aperea (pelo menos duas subespécies, C.a.aperea e C.a.pamparum), C.magna, C.intermedia C.fulgida. Visando contribuir para o conhecimento da anatomia a distinção dessas espécies, descreve-se sincrânio (crânio mandíbula) de exemplares C.a.pamparum do Rio Grande Sul compara-se com C.magna deste estado Santa Catarina, ilha Moleques Sul, na costa catarinense, C.fulgida Minas Gerais Paraná. aperea possui crânio baixo longo; rostro comprimido...
Abstract It is not a new concept that marsupials and placentals are distant distinct clades among mammals. In South America, these animals coexist, occupy similar niches and, in some cases, appearance. This especially true with respect to the locomotor categories of smaller rodents belonging family Cricetidae or, more specifically, subfamily Sigmodontinae, compared Didelphidae family. this study, we have investigated both similarities differences between two by examining locomotion-dependent...
Au cours d'une etude de 19 mois on a evalue, dans les sous-bois la Foret Atlantique, au sud du Bresil, deux methodes alternatives capture des petits mammiferes (<1.000 g).

Understanding resource utilization and economic diversification amongst Holocene hunter‐gatherers in southern Brazil requires in‐depth taphonomic analysis of faunal assemblages. Three Early to Late archaeological sites (Garivaldino, Pilger Sangão) Rio Grande do Sul State, Brazil, revealed large assemblages small mammal (˂1 kg) remains, composed mainly rodents. To appreciate depositional processes fauna relation human consumption, attributes were evaluated. The results indicated that the...
We present the sigmodontine assemblage from lower and middle Holocene recorded in archaeological site RS-TQ-58: Afonso Garivaldino Rodrigues (County of Brochier, State Rio Grande do Sul).A total 16 species are detected study 572 specimens, about half which belonging to tribe Akodontini.The include typically inhabit open areas (e.g.Calomys sp., Gyldenstolpia Kunsia tomentosus) also several considered as forest dewellers (e.g.Delomys Juliomys Sooretamys angouya).Necromys obscurus, a today...
