How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Edaphic and vegetation conditions can render climatically suitable sites inadequate for a species to persist, constraining the amount of suitable habitat and the possibilities of tracking preferred climatic conditions as they shift in response to climate change. We combined climatic and remotely sensed data to model current and future distributions...
Many animal species depend on sound to communicate with conspecifics. However, human‐generated (anthropogenic) noise may mask acoustic signals and so disrupt behavior. Animals may use various strategies to circumvent this, including shifts in the timing of vocal activity and changes to the acoustic parameters of their calls. We tested whether pied...
In this chapter, we consider pathways to work for a future for Amazonia where both humans and other mammals flourish and the rainforest is protected. First we briefly review the tens of millions of years it has taken to develop the current diversity of mammalian fauna living in Amazonia. Humans are a very recent mam-malian arrival to Amazonia at ab...
Mammals are highly diverse in their lifestyles (including semi-and fully aquatic, aerial, terrestrial, fossorial, and arboreal forms). They play fundamental roles in the environments in which they live, acting as pollinators, seed dispersers, ecosystem engineers and top predators at the food chain; they are also involved in the transport of nutrien...
Our aim is to provide an update about what we know and do not know about primates in Brazilian Amazonia, as well as to highlight key threats and to identify research and conservation priorities. Here, we provide a history of primatology in the Brazilian Amazon and a literature review of primate research locations there between 1968 and 2018. Most o...
Fruit availability experienced by different primate species is likely to vary due to species‐specific fruit use, even within the same habitat and timeframe. Pitheciines, primates of the subfamily Pitheciinae , particularly favor the seeds of unripe fruits. Researchers consider this dietary characteristic an adaptation to increase access to fruit re...
The efficient use of food resources is a precondition for wild species´ survival in urban environments. The feeding ecology of animals in tropical cities, however, remains poorly investigated. Here we study the feeding ecology of parrots in Manaus, a major Amazonian city, and compare the results with a parrot assemblage living in undisturbed habita...
We report the first records of Cerdocyon thous on the left bank of the Madeira river, extending its distribution to more than 10 km to the N–W. We carried out a survey of official information present in scientific articles, technical reports, and management plans for conservation units in the state of Rondônia, and accessions to the iNaturalist. Ou...
While some South American primates are well-studied, many are poorly known to science. This makes reports of their ecology very valuable, especially when the region inhabited is threatened by human activities. We combined data from three independent field studies to provide a better understanding of the behavior, ecology, chemical composition of pl...
Assemblage structure and acquisition of high-value resources will usually be affected by changes in resource availability and differential competitive abilities of assemblage members. In fragmented habitats where carrying capacity limits are exceeded due to high population densities and biomass, interspecific interactions can be expected to occur a...
Members of the Neotropical primate genus Chiropotes eat large volumes of immature seeds. However, such items are often low in available proteins, and digestion of seeds is further inhibited by tannins. This suggests that overall plant‐derived protein intake is relatively low. We examined the presence of insect larvae in partially eaten fruits, comp...
We review the extent and nature of scientific knowledge of the Big-headed Amazon River Turtle, Peltocephalus dumerilianus, covering distribution, morphology, taxonomy, diet, behaviour, reproduction, and ecology. We discuss the phylogenetic position of the species and its evolutionary relationships with the other podocnemidids, comparing morphologic...
