Most primates are threatened by tropical forest loss. One population of the critically endangered kipunji monkey Rungwecebus kipunji occurs in a restricted part of one forest in southern Tanzania. This restricted range is something of an enigma. We collated woody vegetation data to assess habitat quality in and around the core kipunji range (Vikongwa) compared to other nearby forests. Habitat quality in Vikongwa was high compared to other regional and African forests, in that tree stem density, basal area, species richness and availability of kipunji dietary species were all comparatively high. However, the nearby Sanje forest, where the kipunji is absent, had comparable habitat to Vikongwa. We concur with previous research that the kipunji is dependent on old growth forest. However, the availability of comparable vegetation in at least one nearby forest suggests that habitat is not the only reason for the kipunji's restricted range.","PeriodicalId":143820,"journal":{"name":"Journal of East African Natural History","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128756751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To further address this topic and to improve our understanding of phylogeographic patterns of baboons in eastern Africa, mitochondrial cytochrome b sequence data were analysed from 148 baboon samples from 103 locations in eastern Africa. The resultant phylogenetic reconstructions suggest an initial split of baboons into four main clades: southern chacma baboons, baboons from Mahale Mountains in Tanzania, main southern, and main northern. We confirm that the boundary between southern and northern clades lies along the Ugalla-Malagarasi River and Ruaha-Rufiji River of central Tanzania. We detected new mitochondrial haplogroups, most notably the Mahale Mountains clade, and refined haplogroup distributions. The evolutionary divergence of baboons in eastern Africa was most likely triggered and maintained by numerous episodes of population division and reconnection, probably related mainly to climate change. To better understand these processes, nuclear DNA information is required, especially to assess gene flow among populations.","PeriodicalId":143820,"journal":{"name":"Journal of East African Natural History","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133192107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Historically, sable herds occurred in the vicinity of Taveta, and in the miombo and Diospyros woodlands of the coastal hinterland from the Tanzania-Kenya border northward for at least 210 km. Most of the historic distribution of sable in Kenya lies 15–35 km inland from the coast at 100–200 m altitude where mean annual rainfall is 800–1200 mm. In terms of numbers, however, most sable occurred in the higher and wetter Shimba Hills (150–460 m; mean annual rainfall 1000–1200 mm). Bachelor males sometimes moved >150 km inland. Much of the decline of the distribution and size of Kenya's sable population occurred during 1950–1980. Sable in Kenya not reported outside of Shimba Hills National Reserve after 1994. Geographic distribution of sable herds in Kenya declined from roughly 5000 km2 in 1884 to 70 km2 today (>98% decline in 132 years). The number of sable in Kenya was already small as of 1884, when there were probably <400 individuals. Kenya's sable population declined from >235 individuals in the mid-1970s to ca. 60 individuals in 2015 (>74% decline in 40 years). Given the low number, small distribution, and rapid decline, sable in Kenya qualifies as a nationally ‘Critically Endangered' species. Recommendations for the conservation of sable in Kenya are provided.","PeriodicalId":143820,"journal":{"name":"Journal of East African Natural History","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114088129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lion home ranges should be expected to temporally fluctuate according to changes in prey biomass. Here we quantified and compared the home range sizes of lions in Uganda with data collected in the 1970's and that collected in the 2000's. Average range sizes of individual lions were 34.0 and 38.1 km2 for the two prides studied, while pride range was 35.7 and 43.1 km2 (Fixed-kernel method). Surprisingly, we found little variation in size of these home ranges between the two periods assessed. Across both periods, lion home ranges tended to be associated with grassland and wooded grassland to woodland, riverine forest and bushland habitats. The core lion home ranges typically overlapped with habitat where Uganda kob (preferred prey in this region) were most abundant and where most kills were made. Buffalo, topi, and waterbuck are avoided while warthog is preyed on in accordance with availability. Range location has not changed greatly since the 1970s although home range size has increased and pride size decreased, possibly in response to lower prey biomass.","PeriodicalId":143820,"journal":{"name":"Journal of East African Natural History","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121914429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These two strengths come together in the study of mammalian colouration where his colour paintings and his black and white drawings depict the patterning of coat colours exceptionally well. Sometimes the underlying morphology and the way that animals show off their pelage patterns are shown too. While artwork is central to Kingdon’s career, resulting in the field guides for which he is so renowned, he has also offered multiple hypotheses regarding the evolutionary history and selective forces underlying colouration in mammals. Some of these hypotheses have been tested and confirmed, others have directed research in new directions, as I show below. Kingdon has long been a champion of functional ideas about mammalian colouration. One of his most memorable findings concerns the crested or maned rat Lophiomys imhausi MilneEdwards 1867 (figure 1).

We employed genetic information from 618 faecal samples to assess the status of forest antelope species in terms of their distribution, intraspecific diversity and population subdivision within the Udzungwa landscape. Most species were detected in the majority of forest fragments, except for Philantomba monticola. Phylogenetic analyses were consistent with traditional taxonomy with the exception of Cephalophus harveyi which was paraphyletic with respect to C. natalensis. There was strong support for three C. harveyi mtDNA clades within the Udzungwa Mountains although nuclear genetic variation did not partition strongly with these maternal lineages. Significant partitioning of genetic variation between sampling areas was detected for all species except the endangered C. spadix. Overall, our results demonstrate the value of non-invasive genetic sampling in studying the distribution and evolution of rarely observed species.","PeriodicalId":143820,"journal":{"name":"Journal of East African Natural History","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122383646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
