Abstract Animal activity patterns correspond to the individual diel cycle time and is an important attribute of species coexistence in ecological communities. However, most Neotropical are still poorly understood. Based on 8‐year camera‐trapping survey conducted between 2009 2017, we evaluated puma ( Puma concolor ) a human‐modified landscape Southeastern Brazil. Our objectives were determine pattern pumas verify influence main prey anthropogenic factors their behavior. We categorized all...
Várzea forests account for 17% of the Amazon basin and endure an annual inundation that can reach 14 m deep during 6–8 months. This flood pulse in combination with topography directly influences várzea vegetation cover. Assemblages several taxa differ significantly between unflooded terra firme flooded forests, but little is known about distribution medium large sized terrestrial mammals habitats. Therefore, our goal was to understand how those habitats influence mammalian species dry...
Abstract Surveying and monitoring of elusive animals with naturally low densities large home ranges, such as many medium‐ large‐sized mammals, is challenging. Low capture rates can preclude detailed analyses. The use bait has been used a strategy to increase carnivore in camera‐trap surveys. Here, we test the effect one type (mix fresh sardine egg) on carnivores prey species survey Central Brazilian Amazon. We also if quality records marked felids for individual identification enhanced by...
Amazonia forest plays a major role in providing ecosystem services for human and sanctuaries wildlife. However, ongoing deforestation habitat fragmentation the Brazilian Amazon has threatened both. The ocelot is an ecologically important mesopredator potential conservation ambassador species, yet there are no previous studies on its preference spatial patterns this biome. From 2010 to 2017, twelve sites were surveyed, totaling 899 camera trap stations, largest known dataset species. Using...
Ocelots (Leopardus pardalis) are presumed to be the most abundant of wild cats throughout their distribution range and play an important role in dynamics sympatric small-felid populations. However, ocelot ecological information is limited, particularly for Amazon. We conducted three camera-trap surveys during consecutive dry seasons estimate density Amanã Reserve, Central Amazonia, Brazil. implemented a spatial capture-recapture (SCR) model that shared detection parameters among surveys. A...
Abstract The Amazon forest has the highest biodiversity on Earth. However, information Amazonian vertebrate diversity is still deficient and scattered across published, peer‐reviewed, gray literature in unpublished raw data. Camera traps are an effective non‐invasive method of surveying vertebrates, applicable to different scales time space. In this study, we organized standardized camera trap records from regions compile most extensive data set inventories mammal, bird, reptile species ever...
The persistent high deforestation rate and fragmentation of the Amazon forests are main threats to their biodiversity. To anticipate mitigate these threats, it is important understand predict how species respond rapidly changing landscape. short-eared dog Atelocynus microtis only Amazon-endemic canid one most understudied wild dogs worldwide. We investigated habitat associations on two spatial scales. First, we used largest record database ever compiled for in combination with distribution...
Abstract The rate of deforestation in the Amazon is increasing. Predictive models estimate that as a result agricultural expansion 40% these forests will be lost by 2050. As consequence habitat forest-dwelling species such Endangered black-faced black spider monkey Ateles chamek being lost, particularly along arc Brazilian Amazon. We used distribution modelling to (1) define this monkey, using environmental predictors, (2) calculate area covered protected network, and (3) expected loss...
The bush dog (Speothos venaticus) is a small Neotropical canid. Although its distribution covers the entire Amazon basin, occurrence of dogs in vast areas remains hypothetical. records presented this study reduce large gap known species Central Amazonia and include 1st documentation from forest seasonally flooded by black water (Igapó).
The bush dog (Speothos venaticus) is a Neotropical canid with wide geographic distribution.Although globally listed as Near Threatened, this species was Vulnerable in recent assessment by the Brazilian government.Few records of mammal have been reported Cerrado, and it considered extinct several localities result human landscape fragmentation.The record presented here first evidence presence West Minas Gerais, Brazil, which augments distribution expected occurrence for region.The study site...
Abstract Climate change will affect species persistence and distribution, particularly in high‐diversity ecosystems like the Amazon. Studies predict that as temperature deforestation increase precipitation patterns Amazon, areas along its southern eastern borders suffer large‐scale savannization, conversion of tropical forest to degraded savannah‐like vegetation. Here, we aim identify terrestrial mammal potentially most at risk from savannization by studying their use natural savannah...
Conservation actions should account for species natural history and behavior related to differences between sexes. However, most studies have not taken into consideration non-independence of observations from the same individual. We used data camera-trap surveys undertaken over six consecutive years investigate habitat use by jaguar (Panthera onca) in varzea seasonally flooded forest. hierarchical modeling assess sex occurrence probability environmental factors, while accounting individual...
Abstract The savannah enclaves (i.e. patches) in the southern Brazilian Amazonia are among most threatened and poorly surveyed sites Amazonia. As part of an extensive mammal survey, we set camera traps three these enclaves. We obtained 23 independent records pampas deer Ozotoceros bezoarticus , a medium sized Neotropical cervid that is strongly associated with open habitats categorized as Vulnerable on Red List species. These confirmed populations lie outside species’ previously presumed...
The aim of the study was to establish pattern agouti pelvis by obtaining external and radiographic internal pelvimetric values.Forty-three (Dasyprocta prymnolopha), females males bred in under human care were used.The parameters measured biiliac diameter; biischiatic right left ilioischiatic diameters measurements (true conjugated, diagonal conjugated; vertical, sacral, sagittal, coxal tuberosity, upper biiliac, lower diameter.The inlet pelvic area outlet calculated, as well height/width...
