| rift valley fever virus among wild ruminants, etosha national park, namibia, 2011. | after a may 2011 outbreak of rift valley fever among livestock northeast of etosha national park, namibia, wild ruminants in the park were tested for the virus. antibodies were detected in springbok, wildebeest, and black-faced impala, and viral rna was detected in springbok. seroprevalence was high, and immune response was long lasting. | 2016 | 26692385 |
| regional genetic structuring and evolutionary history of the impala aepyceros melampus. | samples of 162 impala antelope (aepyceros melampus) from throughout its distribution range in sub-saharan africa were surveyed using eight polymorphic microsatellite loci. furthermore, 155 previously published mitochondrial dna (mtdna) sequences from the same localities were reanalyzed. two subspecies of impala are presently recognized--the isolated black-faced impala (aepyceros melampus petersi) in southwest africa and the common impala (aepyceros melampus melampus) abundant in southern and eas ... | 2006 | 16407525 |
| no suggestion of hybridization between the vulnerable black-faced impala (aepyceros melampus petersi) and the common impala (a. m. melampus) in etosha national park, namibia. | there are two recognized subspecies of impala in sub-saharan africa: the common impala (aepyceros melampus melampus) -- widespread in southern and east africa -- and the vulnerable black-faced impala (a. m. petersi) -- found naturally in only a small enclave in southwest africa. the etosha national park (np) in namibia harbours the largest and only protected-area population of black-faced impala, numbering some 1500 individuals. due to translocations of the exotic common impala to commercial far ... | 2004 | 15367116 |
| health evaluation of black-faced impala (aepyceros melampus petersi) using blood chemistry and serology. | as part of ongoing ecological studies of black-faced impala (aepyceros melampus petersi) in northern namibia, blood samples were collected and analyzed from 26 animals captured for translocation in 1992. all animals appeared to be in good condition and no abnormality was noted during physical examination. serum chemistry and mineral levels were measured and correlated with the results of bacterial and viral serology and were within the normal ranges for domestic ruminants. antibody titers for in ... | 1997 | 9523628 |
