Y-chromosomal Markers Suitable for Noninvasive Studies of Guenon Hybridization
We examine previously-published TSPY sequence data to identify synapomorphies useful for tracking Y-chromosomal gene flow between hybridizing guenon species.We then describe a set of PCR primers and protocols that amplify many of these variable sites from feces. Such Y-chromosomal markers are potentially very useful to conservation studies because they may offer an early sign of […]
Patterns of Vocal Sharing and Social Dynamics in a Captive Group of Campbell’s Monkeys (Cercopithecus campbelli campbelli)
Although vocal sharing is widespread at several phylogenetic levels, few descriptions concerned primates. The present study involved the dynamics of vocal structures and social organization in a captive group of Campbell’s monkeys (Cercopithecus campbelli campbelli) at 3-year periods, using precise sound recording and comparison. The authors focused on combined harmonic 6 calls, often involved in […]
Socially Meaningful Vocal Plasticity in Adult Campbell’s Monkeys (Cercopithecus campbelli)
Campbell’s monkeys (Cercopithecus campbelli) frequently exchange vocalizations, the combined-harmonic calls, with individuals responding to one another’s calls. Previous work has shown that these calls can be grouped into several structural variants. Adult females differ in their variant repertoires, which may change during their adult life, particularly after changes in the group composition. Playback of females’ […]
Pets and pests: vervet monkey intake at a specialist South African rehabilitation centre
Vervet monkeys (Chlorocebus pygerythrus) encounter a plethora of anthropogenic risks as a result of their ability to exploit human-altered environments. A systematic assessment of these risks has not been carried out to date. Here, we aim to begin addressing this gap in our understanding of human-vervet conflict in South Africa. We present a descriptive analysis […]
