Pregnancy complications in wild vervet monkeys in an urban mosaic landscape

Abstract

AbstractVervet monkeys (Chlorocebus pygerythrus) are a widespread, typically seasonally breeding African primate. We report pregnancy complications in wild females in the urban mosaic landscape of Durban, South Africa, that required admittance to a wildlife rehabilitation centre. We found pregnancy complications in 13 female vervet monkey adults and subadults, with most cases (69.2%) in spring. Dystocia (difficult or obstructed labour) was the main cause of admission (46.2%), and in 69.2% of cases, a veterinarian attended to the animal. However, most pregnancy complications resulted in death (86.6%). Concerns about increased anthropogenic food causing increased birth size need further investigation.
