Abstract The PREDICTS project—Projecting Responses of Ecological Diversity In Changing Terrestrial Systems ( https://www.nhm.ac.uk/our-science/our-work/biodiversity/predicts.html )—has collated from published studies a large, reasonably representative database comparable samples biodiversity multiple sites that differ in the nature or intensity human impacts relating to land use. We have used this evidence base develop global and regional statistical models how local responds these measures....
The aim of this paper is to provide a checklist flying and non-flying mammal species which occur in the state Mato Grosso do Sul, delimiting by vegetation domains vulnerability. Records were based on specimens museums, literature, only eventually photos (by camera traps). There are 151 reported or collected state, comprising 10 orders 29 families. richest Chiroptera (61 spp.), Rodentia (35), Carnivora (18), Didelphimorphia (16). families Phyllostomidae (33 species), Cricetidae (23),...
This paper examines the frequencies of mammal roadkill in two adjacent biogeographic ecoregions (Atlantic Forest and Cerrado) Brazil. Mammals were recorded during a seven-year period over 3,900 km roads, order to obtain data for species habitats (sites) killed by cars on roads. Sites (n = 80) within (Cerrado, n 57; Atlantic Forest, 23) searched records mammals. Species surveyed entire region totaled 33, belonging nine orders 16 families. In Cerrado, 31 habitats; these, 25 found dead...
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 Relationships between food habits, home range and activity of the black-eared opossum, Didelphis aurita (Marsupialia, Didelphidae), were studied in an urban forest fragment (5 ha) southern Brazil from February 1995 to January 1996. Captures performed weekly using 30 live-traps placed uniformly study area. Diet was determined through faecal analysis, ranges calculated Minimum Convex Polygon method period assessed time captures night. The opossum proved be insectivorous-omnivorous...
We investigated the density and activity of oncilla, Leopardus tigrinus (Schreber, 1775), a threatened small cat, in Brazilian Atlantic Forest, using camera-trap data. described differences individuals occurring alone or sympatry with larger cats. Oncilla presented low densities (7-13 ind./100 km²) high flexibility its activity. The oncillas were primarily nocturnal absence other cat species - margay, ocelot puma but became more diurnal, cathemeral pattern, when cats present. is likely to be...
Variation in the spatial structure of communities terms species composition (beta diversity) is affected by different ecological processes, such as environmental filtering and dispersal limitation. Large rivers are known barriers for (riverine hypothesis) tropical regions. However, when organisms not limited geographic barriers, other factors, climatic conditions distance per se, may affect distribution. In order to investigate relative contribution major rivers, climate on Passeriformes...
Mammal abundance, richness, and community structure were examined in fragments of savannah gallery forests south-western Brazil order to assess the influence fragment size habitat on communities. Five two sampled. Within fragments, environmental parameters such as tree shrub densities measured. Live-traps pitfalls used for trapping small mammals; larger mammals recorded from footprints sightings. Seventeen species mammal 15 large recorded. Small affected by isolation, whereas not....
Abstract This study aimed to compare the efficacy of different trapping methodologies for sampling small mammals, consisting trap type (pitfall, Sherman, and wire traps) position (ground understorey) in Cerrado biome Brazil. Five fragments woodland savannah were selected study. We captured a total 364 individuals 14 species mammals. Pitfall traps sampled all (100%), whereas ground cage 8 (57%), arboreal 5 (36%). The gave significantly results, particularly between pitfall traps, traps....
Few studies have addressed mortality causes of neotropical mammals on roads, especially considering the extensive road system and biodiversity. The goal this article was to examine biological factors related non-volant roads an Atlantic Forest–Cerrado interface in Brazil. Mammals were recorded during a seven-year period over 3900 km order estimate data for abundance species habitats (areas) frequencies killed by cars roads. Areas (n = 80) within two adjacent ecoregions (Atlantic Forest, n...
Species morphological changes can be mutually influenced by environmental or biotic factors, such as competition. South American canids represent a quite recent radiation of taxa that evolved forms very disparate in phenotype, ecology and behaviour. Today, the central part America there is one dominant large species (the maned wolf, Chrysocyon brachyurus) directly influence sympatric smaller via interspecific killing. Further south, three similar sized foxes (Lycalopex spp.) share same...
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...
Chewing on different food types is a demanding biological function. The classic assumption in studying the shape of feeding apparatuses that animals are what they eat, meaning adaptation to items accounts for most their interspecific variation. Yet, growing body evidence points against this concept. We use primate mandible as model structure investigate complex interplay among shape, size, diet, and phylogeny. find weak but significant impact diet variation primates whole not anthropoids...
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,...
Didelphis albiventris and D. aurita are Neotropical marsupials that share a unique evolutionary history both largely distributed throughout South America, being primarily allopatric their ranges. In the Araucaria moist forest of Southern Brazil these species sympatric they might potentially compete having similar ecology. For this reason, ideal biological models to address questions about ecological character displacement how closely related geographic space. Little is known two...

We carried out a mammalian survey in the neighborhoods of Serra da Bodoquena National Park, Mato Grosso do Sul state, region poorly known southwestern Brazil. During months April, May and July 2002 we used wire live trap, direct observation, indirect evidence (e.g. tracks), carcasses, interviews with local residents to record species. Fifty six mammal species were recorded, including threatened (14%). These records discussed regarding abundance, distribution, range extension, habitat,...
Abstract We examined the community composition and abundance of small mammals in vertical strata gallery forests woodland savannahs south-western Brazil. Captures were carried out during winter summer months 2006/2007. Traps set three transect lines per habitat, with 10 capture stations on each line. Each station had traps: ground, understorey (2–3 m height), canopy (8–10 m) physiognomy. With an effort 3600 trap-nights, 11 species captured, which distributed differently regarding forest...
We investigated the richness, composition, and species relative abundance of a terrestrial small mammal community in Deciduous Forest area austral boundary Atlantic Forest. The microhabitat use most common was also investigated. Six rodents - Akodon montensis (Thomas, 1913), Oligoryzomys nigripes (Olfers, 1818), Sooretamys angouya Thaptomys nigrita (Lichtenstein, 1829), Mus musculus (Linnaeus, 1758) Juliomys sp. one marsupial Didelphis albiventris (Lund, 1840) were captured. is recorded...
