Variation of tsetse fly abundance in relation to habitat and host presence in the Maasai Steppe, Tanzania

Human activities modify ecosystem structure and function and can also alter the vital rates of vectors and thus the risk of infection with vector-borne diseases. In the Maasai Steppe ecosystem of northern Tanzania, local communities depend on livestock and suitable pasture that is shared with wildlife, which can increase tsetse abundance and the risk of trypanosomiasis. We monitored the monthly tsetse fly abundance adjacent to Tarangire National Park in 2014-2015 using geo-referenced, baited epsilon traps. We examined the effect of

Modélisation de la distribution spatiale de la girafe (Giraffa camelopardalis peralta, Linnaeus 1758) de l’Afrique de l’Ouest pour sa conservation au Niger

La conservation de la girafe (Giraffa camelopardalis peralta, Linnaeus 1758), nécessite la connaissance de son aire de répartition potentielle et des facteurs environnementaux conditionnant cette répartition. Cette étude visait à identifier les facteurs écologiques régissant la répartition géographique de la girafe et la cartographie de son aire de distribution sous les conditions climatiques actuelles pour une meilleure planification de sa gestion durable. La modélisation a été utilisée pour cartographier l’habitat de la girafe suivant les modèles climatiques (CCMA et CSIRO),

Large herbivore dynamics in northern Gonarezhou National Park, Zimbabwe

We compared densities and distribution of wild ungulates and domestic livestock based on aerial surveys conducted during 1991 – 2010 in northern parts of Gonarezhou National Park (GNP), Zimbabwe. The sampled area covered approximately 320 km2 (Chipinda Pools area) representing ca. 27 % of the GNP, which was colonized by a few herder families along with their cattle in the year 2000. We hypothesized that (1) human and livestock encroachment in the park would lead to decline in densities of

Interaction entre hommes et girafes dans la zone de distribution de la girafe au Niger

Cette étude qui porte sur l’interaction entre hommes et girafes a été menée dans la zone de distribution de la girafe du Niger dénommée « aire girafe ». Elle a concerné douze (12) villages répartis sur les deux (2) foyers de distribution, la zone centrale et la zone de Fandou. Au total, 218 personnes ont été enquêtées et les données comparées entre villages et entre foyers de troupeau de girafes. Les résultats montrent que les dégâts sur les cultures et

Maintaining the Population of Thornicroft Giraffes (Giraffa camelopardalis thornicrofti)

There is a lack of information on the Thornicroft giraffe’s population size and of the amount of poaching taking place on the giraffes with in the Southern Luangwa Valley National Park. As of right now the giraffes population appears to be stable but there are a lot of factor unknown pertaining to the threats to the population and to their habitat. The goal of this management plan is to maintain the Thornicroft Giraffes population which is exclusively found in Luangwa

Body size and habitat as determinants of tick infestations of wild ungulates in South Africa

The purpose of the present work was to test the hypothesis that the intensity of tick infestation on South African wild ungulates is proportional to surface area of the host (body weight 0.67} and to assess the role of habitat preference on the intensity of infestations. The results support previous suggestions that larger ungulates are more important hosts for adult ticks, however, the intensity of infestation of nymphs and larvae is proportional to the surface area of the host. Grazers

Ecology, Behaviour and Conservation Status of Masai Giraffe (Giraffa camelopardalis tippelskirchi) in Tanzania

The focus of this thesis is on the behaviour, ecology and conservation of Masai giraffe (Giraffa camelopardalis tippelskirchi) in Tanzania. Giraffes are the most elegant, conspicuous and tallest animals of the African savannah. Giraffes prefer savannah and are responsible for the architectural beauty of trees through browsing. Giraffes are social but are non territorial because individuals within a group are in constant change. Females are more often in mixed herds with calves, whereas males maintain a primarily solitary life. Giraffes

Giraffa camelopardalis, Giraffe Assessment by: Muller, Z. et al.

Taxonomic Notes: The IUCN SSC Giraffe and Okapi Specialist Group (GOSG) currently recognizes a single species, Giraffa camelopardalis. Nine subspecies of Giraffes are currently recognized (Dagg 2014), although some authorities dispute this taxonomic classification (e.g., Groves and Grubb 2011). Several subpopulations of Giraffe, resident in northern Botswana, northwest Zimbabwe, northeastern Namibia and southwestern Zambia, are potentially either G. c. angolensis, or G. c. giraffa but the continued accumulation of information indicates that a future reassessment might be in order. Until

The diet selection, habitat preferences and spatial ecology of relocated giraffe (Giraffa camelopardalis) in the Kgalagadi Transfrontier Park

Old records and historic eyewitness accounts of giraffe (Giraffa camelopardalis) in the Kalahari, led to the decision by park management to reintroduce giraffe in 1991. Twenty years ago (1991) the translocation of 8 giraffe from the Etosha National Park took place to an area in the Kgalagadi Transfrontier Park which there is limited information as to their adaptation success or potential impact on the environment. The giraffe was transported to a specially built boma measuring a few hundred hectares in

The Ecology and Behaviour of Giraffe in Northern Botswana

Northern Botswana is one of the giraffe strongholds across its geographic range in the absence of, or with low impact from, the major anthropological threats faced elsewhere. Yet despite its conservation significance, until now, no giraffe specific ecological or behavioural studies have been undertaken. Moreover, Africa’s giraffe population has been significantly reduced over the last two decades, and the pressure on giraffe habitats and populations is likely to increase as the human population continues to expand, and the effects of
