Abstract Anthropogenic hybridization is an increasing conservation threat worldwide. In South Africa, recent threatening numerous ungulate taxa. For example, the genetic integrity of near‐threatened bontebok ( Damaliscus pygargus ) threatened by with more common blesbok D. p. phillipsi ). Identifying nonadmixed parental and admixed individuals challenging based on morphological traits alone; however, molecular analyses may allow for accurate detection. Once hybrids are identified, population...
The Southern Ground-hornbill (SGH) (Bucorvus leadbeateri) is considered an umbrella species for biodiversity conservation in savannah biomes since they require large territories and significant protection measures that help to conserve a wide range of with similar savanna grassland requirements. Declines the are attributed low reproductive rates coupled multiple anthropogenic threats, including secondary poisoning, persecution. Little known about connectivity population structure SGH...
The Cape mountain zebra (Equus zebra) is a subspecies of endemic to South Africa. experienced near extinction in the early 1900's and their numbers have since recovered more than 4,800 individuals. However, there are still threats long-term persistence. A previous study reported that had low genetic diversity three relict populations urgent conservation management actions were needed mitigate risk further loss. As these suggestions went largely unheeded, we undertook present study, fifteen...
Abstract Many recent contributions have made a compelling case that genetic diversity is not adequately reflected in international frameworks and policies, as well local governmental processes implementing such frameworks. Using digital sequence information (DSI) other publicly available data supported to assess diversity, toward formulation of practical actions for long‐term conservation biodiversity, with the particular goal maintaining ecological evolutionary processes. Given inclusion...
Biological diversity is being lost at unprecedented rates, with genetic admixture and introgression presenting major threats to biodiversity. Our ability accurately identify critical manage species, obtain insights into evolutionary processes, ultimately contribute the Aichi Targets developed under Convention on Diversity. The current study concerns roan antelope, second largest antelope in Africa. Despite their large size, these are sensitive habitat disturbance interspecific competition,...
Abstract Globally, levels of human–wildlife conflict are increasing as a direct consequence the expansion people into natural areas resulting in competition with wildlife for food and other resources. By being forced increasingly smaller pockets suitable habitat, many animal species at risk becoming susceptible to loss genetic diversity, inbreeding depression associated inability adapt environmental changes. Predators often lethally controlled due their threat livestock. such jackals (black...
Hybridization in antelope species has been widely reported South African national parks and provincial reserves as well on private land due to anthropogenic effects. In a closed management setting, hybridization may occur the crossbreeding of closely related with unequal sex ratios, resulting either sterile or fertile offspring. this study, we used molecular techniques evaluate risk between blesbok (
Biological diversity is being lost at unprecedented rates, with admixture and introgression presenting major threats to species’ conservation. To this end, our ability accurately identify critical manage species, obtain insights into evolutionary processes, ultimately contribute the Aichi Targets developed under Convention on Diversity. A case in hand concerns roan antelope, one of Africa’s most iconic large mammal species. Despite their size, these antelope are sensitive habitat disturbance...
