The Amazon forest has the highest biodiversity on earth. However, information on Amazonian vertebrate diversity is still deficient and scattered across the published, peer‐reviewed and grey literature and in unpublished raw data. Camera traps are an effective non‐invasive method of surveying vertebrates, applicable to different scales of time and s...
Article
Animal coloring serves several functions, including camouflage and thermoregulation. However, some individuals have anomalous coloring patterns due to excess (melanism) or deficiency (albinism, leucism, or piebaldism) in melanin production. Although these anomalies occur in several species, there are few cited cases. Here, we report the occurrence...

O crescente processo de desmatamento do bioma Amazônia afeta diversas espécies animais, especialmente os primatas. Mico rondoni e Leontocebus weddelli são espécies endêmicas do sul da floresta amazônica e habitam preferencialmente florestas primárias. Possuem conhecida distribuição simpátrica em algumas localidades, podendo formar grupos mistos e c...

Endangered crowned solitary eagle in the threatened Amazonian savannah - Volume 53 Issue 4 - Daniel G. Rocha, Laurie Hedges, Bruno C. Cambraia
Article
Full-text available
Amazonia forest plays a major role in providing ecosystem services for human and sanctuaries for wildlife. However, ongoing deforestation and habitat fragmentation in the Brazilian Amazon has threatened both. The ocelot is an ecologically important mesopredator and a potential conservation ambassador species, yet there are no previous studies on it...
Article
The rate of deforestation in the Amazon is increasing. Predictive models estimate that as a result of agricultural expansion 40% of these forests will be lost by 2050. As a consequence the habitat of forest-dwelling species such as the Endangered black-faced black spider monkey Ateles chamek is being lost, particularly along the arc of deforestatio...

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 the várzea vegetation cover. Assemblages of several taxa differ significantly between unflooded terra firme and flooded várzea forests, but little is known...
Data
Medium and large mammalian species records and the number of camera trap stations with records in várzea and terra firme forests, Central Amazonia, Brazil. (XLSX)
Data
Student t-test to evaluate the possible influence of the use of bait in the records of medium and large mammalian species in camera trap stations in várzea of Mamirauá Sustainable Development Reserve, Central Amazonia, Brazil. ‘No bait’ is a comparison of baited and unbaited stations, while ‘Control’ is a comparison of stations with the same treatm...
Data
Best models result for medium and large size mammals in relation to predictor variables in várzea of Mamirauá Sustainable Development Reserve, Central Amazonia, on the 500 m and 1000 m scales. GLM = Generalized Linear Model; ZIP = Zero-Inflated Poisson. GLM distributions were: G = gaussian; P = poisson; QP = quasi-poisson and NB = negative binomial...
Article
Animal activity patterns correspond to the individual diel cycle time and is an important attribute of species coexistence in ecological communities. However, activity patterns of most Neotropical species are still poorly understood. Based on an 8-year camera-trapping survey conducted between 2009 and 2017, we evaluated puma (Puma concolor) activit...
Article
Ongoing deforestation in Southeast Asia is leading to increased fragmentation and reduction of habitat for the mainland clouded leopard (Neofelis nebulosa). Using the largest detection/non-detection camera trap survey dataset known for the species throughout its range, we investigated factors affecting clouded leopard habitat use across Peninsular...

The bush dog (Speothos venaticus) is a Neotropical canid with a wide geographic distribution. Although globally listed as Near Threatened, this species was listed as Vulnerable in a recent assessment by the Brazilian government. Few records of this mammal have been reported in the Brazilian Cerrado, and it is considered extinct in several localitie...

Article
The bush dog (Speothos venaticus) is a small Neotropical canid. Although its distribution covers the entire Amazon basin, the occurrence of bush dogs in vast areas of the Amazon remains hypothetical. The records of bush dogs presented in this study reduce a large gap in the known distribution of the species in Central Amazonia and include the 1st d...

This article provides new occurrence records for Platemys platycephala platycephala. The individuals were collected in two sites in the Amanã Sustainable Development Reserve and one site in the Rio Jutaí Extractive Reserve, in Amazon state, Brazil. These records extend the species distribution in the Central Amazon, where there was a gap of more th...

Each kind of trap tends to be selective on species sampled, in a way that each one only reveals part of the abundance and species richness of the community sampled. In this way, in order to know the factors that affect the success of sampling methods is crucial for a better planning of experiments and data analysis. The aim of this study was to eva...

Densidade e número de indivíduos são informações essenciais para a conservação e o manejo efetivo de uma população. Para a raposa-do-campo, praticamente inexistem estimativas de densidade e tamanho populacional na literatura, exceto a conduzida por Rocha e colaboradores (2008). Uma das ações de conservação sugerida para a espécie em diferentes trabalhos é a realização de estudos sobre densidade, abundância relativa e tendências populacionais que comparem áreas protegidas com áreas sob diferentes níveis de pressão antrópica. Recentemente, a raposa-do-campo foi listada como ameaçada de extinção no Brasil, na categoria “Vulnerável”. Concomitantemente, sua região de ocorrência natural vem sofrendo excepcional perda de biodiversidade nos últimos tempos, logo, conhecer quantas raposas existem em áreas antropizadas pode ajudar a traçar estratégias de conservação para a espécie. Visando preencher parte desta lacuna, o objetivo deste estudo é estimar a densidade e o número de indivíduos de uma população de raposas-do-campo, considerando seus aspectos temporais e espaciais de história de vida, em uma área de fazendas de gado no município de Cumari, Goiás, Brasil.
