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 ...200616407525
a seasonal survey of gastrointestinal parasites in captive wild impala antelope on a game facility south of lusaka, zambia.faecal samples (n = 1947) from captive wild impala (aepyceros melampus melampus) were examined over a period of 14 months to determine quantitative seasonal helminth egg excretion patterns and qualitative protozoan oocyst excretion patterns. geometric mean monthly faecal egg counts (fecs) ranged from 20 to 575 and coprocultures revealed three parasite genera, namely trichostrongylus, haemonchus and strongyloides. larvae of the trichostrongylus spp. were most predominant from faecal cultures. no ...201122071007
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 ...200415367116
examination of the rumen bacteria and methanogenic archaea of wild impalas (aepyceros melampus melampus) from pongola, south africa.although the rumen microbiome of domesticated ruminants has been evaluated, few studies have explored the rumen microbiome of wild ruminants, and no studies have identified the rumen microbiome in the impala (aepyceros melampus melampus). in the present study, next-generation sequencing and real-time polymerase chain reaction were used to investigate the diversity and density of the bacteria and methanogenic archaea residing in the rumen of five adult male impalas, culled during the winter dry s ...201525351144
