Social networks, long-term associations and age-related sociability of wild giraffes
Long-term studies of sociality in wild animals are rare, despite being critical for determining the benefits of social relationships and testing how long such relationships last and whether they change as individuals age. Knowledge about social relationships in animal species that exhibit fission-fusion dynamics can enhance our understanding of the evolution of close social bonds […]
Home range and seasonal movements of Giraffa camelopardalis angolensis in the northern Namib Desert
Estimates of home range size of giraffe in the northern Namib Desert were on average larger than those in other populations. In particular, the largest individual home range of any giraffe bull (1950 km2) was recorded – correlated with low population density, reduced forage density and increased searching for receptive cows. The predominant pattern of […]
Genetic structure of two populations of the Namibian giraffe, Giraffa camelopardalis angolensis
Two geographically distinct populations of giraffe (Giraffa camelopardalis) were sampled for this study, the northern Namib Desert and Etosha National Park. Population genetic parameters and relationships within subpopulations were estimated to better understand the genetic architecture of this isolated subspecies. Gene flow between the geographically separated populations can be attributed to recent translocation of giraffe […]
Distribution and status of the desert-dwelling giraffe (Giraffa camelopardalis angolensis) in northwestern Namibia
The population density and distribution of desert-dwelling giraffes was estimated in three study areas in the Hoanib River catchment, northwestern Namibia. Giraffe population densities (0.01 giraffe/km^2) were equal to the lowest recorded in Africa with population numbers fluctuating over past decades. Sex ratios, herd sizes and age categories differed between all the study areas, while […]
An overview of giraffe giraffa camelopardalis taxonomy, distribution and conservation status, with a Namibian comparative and focus on the Kunene Region.
Limited knowledge of the giraffe’s taxonomy, distribution and conservation status currently exists at the species and subspecies level. This lack of understanding has compounded the species long-term conservation Africa-wide, including in Namibia where waves have been made regarding the species potential conservation down listing based on little, if any, scientific evidence. This study provides the […]
Analysis of Angolan Giraffe (Giraffa camelopardalis angolensis) Post-Translocation Movement Patterns and Implications for Conservation Management in Namibia
Wildlife translocation is a conservation management strategy that has been employed to bolster many diminishing wild animal populations. Giraffe translocations are currently being conducted in Africa, but the consequences of such remain largely unknown. In Namibia, translocations are conducted to re-establish locally extirpated populations or to recover vulnerable ones in and around communal conservancies. This […]
Mitochondrial sequences reveal a clear separation between Angolan and South African giraffe along a cryptic rift valley
Background: The current taxonomy of the African giraffe (Giraffa camelopardalis) is primarily based on pelage pattern and geographic distribution, and nine subspecies are currently recognized. Although genetic studies have been conducted, their resolution is low, mainly due to limited sampling. Detailed knowledge about the genetic variation and phylogeography of the South African giraffe (G. c. […]
