Article
Two species of warthog are currently widely recognised, the poorly known desert warthog Phacochoerus aethiopicus and the widely distributed common warthog Phacochoerus africanus. Spatial data for both species were collected during field surveys and from the literature, museums, colleagues, naturalists, local experts, and online resources to assess...

Estimating population densities and their trends over time is essential for understanding primate ecology and for guiding conservation efforts. From 2011 through to 2019, we counted two guenon species during seasonal road transect surveys in Lake Manyara National Park: the Tanzania-endemic Manyara monkey Cercopithecus mitis manyaraensis (Internatio...
Article
Full-text available
African wild pigs have a contentious evolutionary and biogeographic history. Until recently, desert warthog (Phacochoerus aethiopicus) and common warthog (P. africanus) were considered a single species. Molecular evidence surprisingly suggested they diverged at least 4.4 million years ago, and possibly outside of Africa. We sequenced the first whol...

In 2020, a new subspecies was described in the Cercopithecus mitis complex, the Manyara monkey C. m. manyaraensis, Butynski & De Jong, 2020. The internal taxonomy of this species complex is still debated, and the phylogenetic relationships among the taxa are unclear. Here we provide the first mitochondrial sequence data for C. m. manyaraensis to de...
Chapter
The Colobines are a group of Afroeurasian monkeys that exhibit extraordinary behavioural and ecological diversity. With long tails and diverse colourations, they are medium-sized primates, mostly arboreal, that are found in many different habitats, from rain forests and mountain forests to mangroves and savannah. Over the last two decades, our unde...

Desert warthog Phacochoerus aethiopicus delamerei and common warthog Phacochoerus africanus are widespread and locally common in the Horn of Africa and Kenya, east of the Eastern Rift Valley. It is of particular interest that these two taxa, the only two extant species in the genus Phacochoerus, occur in sympatry in some regions. Within Kenya, symp...

The classification of most mammalian orders and families is under debate and the number of species is likely greater than currently recognized. Improving taxonomic knowledge is crucial, as biodiversity is in rapid decline. Morphology is a source of taxonomic knowledge, and geometric morphometrics applied to two dimensional (2D) photographs of anato...
