| community-based wildlife management area supports similar mammal species richness and densities compared to a national park. | community-based conservation models have been widely implemented across africa to improve wildlife conservation and livelihoods of rural communities. in tanzania, communities can set aside land and formally register it as wildlife management area (wma), which allows them to generate revenue via consumptive or nonconsumptive utilization of wildlife. the key, yet often untested, assumption of this model is that economic benefits accrued from wildlife motivate sustainable management of wildlife. to ... | 2020 | 31993122 |
| the host-specificity of theileria sp. (sable) and theileria sp. (sable-like) in african bovidae and detection of novel theileria in antelope and giraffe. | tick-borne diseases caused by theileria are of economic importance in domestic and wildlife ruminants. the majority of theileria infects a limited number of host species, supporting the concept of host specificity. however, some theileria seem to be generalists challenging the host specificity paradigm, such as theileria sp. (sable) reported from various vertebrate hosts, including african buffalo, cattle, dogs and different antelope species. we tested the hypothesis that t. sp. (sable) uses bov ... | 2020 | 31566155 |
| long-term historical and projected herbivore population dynamics in ngorongoro crater, tanzania. | the ngorongoro crater is an intact caldera with an area of approximately 310 km2 located within the ngorongoro conservation area (nca) in northern tanzania. it is known for the abundance and diversity of its wildlife and is a unesco world heritage site and an international biosphere reserve. long term records (1963-2012) on herbivore populations, vegetation and rainfall made it possible to analyze historic and project future herbivore population dynamics. nca was established as a multiple use ar ... | 2020 | 32155150 |
| effect of zebra skin-derived compounds on field catches of the human african trypanosomiasis vector glossina fuscipes fuscipes. | the riverine tsetse fly glossina fuscipes fuscipes is a major vector of trypanosome pathogens causing african trypanosomiasis. this fly species uses a combination of olfactory and visual cues to locate its hosts. previously, traps and targets baited with visual cues have been used in vector control, but the development of olfactory-based tools has been challenging. recently, repellents have shown promise as olfactory-based tools in tsetse vector control. here, we evaluated a three-component blen ... | 2020 | 33160957 |
| blending studies with selected waterbuck odor constituents or analogues in the development of a potent repellent blend against savannah tsetse. | previous comparison of the body odors of tsetse-refractory waterbuck and those of tsetse-attractive ox and buffalo showed that a blend of 15 eag-active compounds specific to waterbuck, including c5-c10 straight chain carboxylic acid homologues, methyl ketones (c8-c12 straight chain homologues and geranyl acetone), phenols (guaiacol and carvacrol) and δ-octalactone, was repellent to tsetse. a blend of four components selected from each class of compounds (δ-octalactone, pentanoic acid, guaiacol, ... | 2020 | 32592683 |
| cellular and molecular targets of waterbuck repellent blend odors in antennae of glossina fuscipes fuscipes newstead, 1910. | insects that transmit many of the world's deadliest animal diseases, for instance trypanosomosis, find their suitable hosts and avoid non-preferred hosts mostly through olfactory cues. the waterbuck repellent blend (wrb) comprising geranylacetone, guaiacol, pentanoic acid, and δ-octalactone derived from waterbuck skin odor is a repellent to some savannah-adapted tsetse flies and reduces trap catches of riverine species. however, the cellular and molecular mechanisms associated with detection and ... | 2020 | 32581714 |
| responses of glossina fuscipes fuscipes to visually attractive stationary devices baited with 4-methylguaiacol and certain repellent compounds in waterbuck odour. | a blend of compounds (pentanoic acid, guaiacol, δ-octalactone and geranylacetone) identified in waterbuck (kobus defassa) body odour referred to as waterbuck repellent compounds (wrc) and a synthetic repellent 4-methylguaiacol have previously been shown to repel tsetse flies from the morsitans group. however, these repellents have not been evaluated on palpalis group tsetse flies. in this study, we evaluated the effect of these repellents on catches of glossina fuscipes fuscipes (major vector of ... | 2019 | 31276492 |
| bilirubin concentrations in clinically healthy and diseased captive waterbuck (kobus ellipsiprymnus) at the san diego zoo safari park. | captive waterbuck ( kobus ellipsiprymnus ) that appear clinically healthy have been noted to have high serum bilirubin concentrations compared with other ruminants; however, questions remain about the physiologic factors affecting bilirubin concentration and its potential association with underlying disease and icteric serum or mucous membranes. serum bilirubin concentrations of healthy and diseased waterbuck housed at the san diego zoo safari park from 1989 to 2012 were retrospectively analyzed ... | 2016 | 27468025 |
| animal health problems attributed to environmental contamination in lake nakuru national park, kenya: a case study on heavy metal poisoning in the waterbuck kobus ellipsiprymnus defassa (ruppel 1835). | a study was conducted in which samples of soil, forage, as well as serum, bone, kidney, and liver of waterbuck were collected from lake nakuru national park. the objective was to determine the ecosystem health status in order to establish the causes of animal health problems previously recorded in some sections of the park. trace element analysis in serum indicated occurrence of copper (cu) deficiency in the north and eastern sections of the park where mean values were marginal (range: 0.36-0.81 ... | 2007 | 17160492 |
| hybridization between subspecies of waterbuck (kobus ellipsiprymnus) in zones of overlap with limited introgression. | two subspecies of waterbuck (kobus ellipsiprymnus), common (kobus ellipsiprymnus ellipsiprymnus) and defassa (kobus ellipsiprymnus defassa), are recognized based on differences in rump pattern, coat colour and geographical distribution. these forms are parapatrically distributed with an area of range overlap in east africa, where phenotypically intermediate populations occur. variation in 478 bp of the mitochondrial dna control region and 14 polymorphic microsatellite loci were used to describe ... | 2006 | 17032274 |

| peste des petits ruminants virus infection at the wildlife-livestock interface in the greater serengeti ecosystem, 2015-2019. | peste des petits ruminants (ppr) is a viral disease of goats and sheep that occurs in africa, the middle east and asia with a severe impact on livelihoods and livestock trade. many wild artiodactyls are susceptible to ppr virus (pprv) infection, and some outbreaks have threatened endangered wild populations. the role of wild species in pprv epidemiology is unclear, which is a knowledge gap for the global strategy for the control and eradication of ppr. these studies aimed to investigate pprv inf ... | 2021 | 34066336 |
