Viability analysis of Kordofan giraffe (Giraffa camelopardalis antiquorum) in a protected area in Cameroon

Representing one of the last populations of an IUCN Critically Endangered subspecies, estimates suggest the Kordofan giraffe of Cameroon’s Bénoué Complex number fewer than 300 individuals, threatened by poaching and habitat degradation. This study investigated the viability of Bénoué National Park’s Kordofan giraffe and efficacy of available interventions through a population viability analysis using VORTEX. The relative impacts of anti-poaching activity, population supplementation, habitat protection and vaccination were explored, alongside a sensitivity analysis investigating parameter uncertainty. The baseline model projects

Ecology of South African large herbivores in a managed arid savanna: body mass, local distribution, and parasites.

Large herbivores are an important natural resource for humans, but a high proportion of these species are classified as globally endangered. Current declines of these species are mainly caused by unsustainable harvesting and land use loss or conversion. These processes frequently increase herbivore mortality rates, and alter a species’ behaviour and local distributions. Because of their importance, humans frequently attempt to manage large herbivores to assure their sustainable use and effective protection. Nevertheless, these actions usually focus on managing and

Mitochondrial DNA variability in Giraffa camelopardalis: consequences for taxonomy, phylogeography and conservation of giraffes in West and central Africa

The giraffe (Giraffa camelopardalis) still survives in four countries of West and central Africa. The populations of Niger and Cameroon are generally assigned to the subspecies peralta, but those of Chad and the Central African Republic are taxonomically problematic, as they are referred to as either peralta, or antiquorum, or congoensis. In this study, a mitochondrial fragment of 1765 nucleotide sites, covering the complete cytochrome b gene, three transfer RNAs and a large part of the control region, was sequenced
