Persistent anthrax as a major driver of wildlife mortality in a tropical rainforest [PDF]
, 2017 Anthrax is a globally important animal disease and zoonosis. Despite this, our current knowledge of anthrax ecology is largely limited to arid ecosystems, where outbreaks are most commonly reported.

Categories as paradigms for comparative cognition [PDF]
, 1998 Forming categories is a basic cognitive operation allowing animals to attain concepts, i.e. to represent various classes of objects, natural or artificial, physical or social. Categories can also be formed about the relations holding among these objects,

The phylogeography of orangutan foamy viruses supports the theory of ancient repopulation of Sumatra [PDF]
, 2004 Phylogenetic analysis of foamy virus sequences obtained from Bornean and Sumatran orangutans showed a distinct clustering pattern. One subcluster was represented by both Bornean and Sumatran orangutan simian foamy viruses (SFV). Combined analysis of host

Object-based attention in chimpanzees (Pan troglodytes)
Vision Research, 2010 We conducted three experiments to investigate how object-based components contribute to the attentional processes of chimpanzees and to examine how such processes operate with regard to perceptually structured objects. In Experiment 1, chimpanzees responded to a spatial cueing task that required them to touch a target appearing at either end of two ...

Genetic Influences on Receptive Joint Attention in Chimpanzees (Pan troglodytes)
Scientific Reports, 2014 Despite their genetic similarity to humans, our understanding of the role of genes on cognitive traits in chimpanzees remains virtually unexplored. Here, we examined the relationship between genetic variation in the arginine vasopressin V1a receptor gene

The Final (Oral Ebola) Vaccine Trial on Captive Chimpanzees? [PDF]
, 2017 Could new oral vaccine technologies protect endangered wildlife against a rising tide of infectious disease? We used captive chimpanzees to test oral delivery of a rabies virus (RABV) vectored vaccine against Ebola virus (EBOV), a major threat to wild ...

Dietary Adaptations and Intra- and Interspecific Variation in Dental Occlusal Shape in Hominin and Non-hominin Primates [PDF]
, 2016 Dental morphology and tooth shape have been used to recreate the dietary adaptations for extinct species, and thus dental variation can provide information on the relationship between fossil species and their paleoenvironments.
