Abstract Conservation and development organizations around the world are increasingly promoting livelihood programs for rural communities as a means of creating sustainable alternatives to activities destructive remaining wildlife habitats. In impoverished in Colombia adjacent forest patches with critically endangered cotton‐top tamarins ( Saguinus oedipus ), this study evaluates alternative pr...

Previous research suggests that nonhuman primates have limited flexibility in the frequency content of their vocalizations, particularly when compared to human speech. Consistent with this notion, several nonhuman primate species have demonstrated noise-induced changes in call amplitude and duration, with no evidence of changes to spectral content. This experiment used broad- and narrow-band no...

GB virus B (GBV-B) is the closest relative of hepatitis C virus (HCV) and is an attractive surrogate model for HCV antiviral studies. GBV-B induces an acute, resolving hepatitis in tamarins. Utilizing primary cultures of tamarin hepatocytes, we have previously developed a tissue culture system that exhibits high levels of GBV-B replication. In this report, we have extended the utility of this s...

Sleep quantitation data on the Neotropical primate species, apart from the squirrel monkey, are still sparse. As such, we have quantitated sleep in the common marmosets (Callithrix jacchus), cotton top tamarins (Saguinus oedipus) and squirrel monkeys (Saimiri sciureus) reared in one primate facility simultaneously, by non-invasive actigraphy. The range in total sleep time/24h measured for male ...

In primates, long-range communication is often mediated by the use of ‘long’ (or ‘loud’) calls. Beyond the acoustic classification of these calls and descriptions of the behavioural context in which they are produced, few experimental studies have examined how species-typical information is encoded in the structure of these signals. We present the results of eight experimental conditions design...

The three forms of Leontopithecus are among the most $ endangered of Brazil's primate fauna. For the past 20 years Coimbra-Filho and colleagues have been working to ensure the survival of lion tamarins in their original habitat in the unique southeastern coastal forests of Brazil. Simultaneously, both Brazilian and international efforts have focused on the development of management techniques t...

To maximize transmission in noisy environments, vocalizing animals have evolved capacities to avoid the masking effects of biotic and abiotic sound sources, such as changing the structure and timing of acoustic signals. Here we explore this problem from a new angle, asking whether animals can extract predictive acoustic cues from an intermittently noisy environment and use this information to g...
