Impacts of Bush thinning to livestock and Biodiversity in Soysambu Conservancy
The continuing bush thinning in Soysambu Conservancy (Delamere estates) to increase the grazing fields lead to establishment of the study. The main objective of this study was therefore to determine the effectiveness of bush thinning as management tool in rangeland management and determine the utilization of the thinned areas by both livestock and wild animals […]
Does illegal hunting skew Serengeti wildlife sex ratios?
In this article we show that the population of Serengeti Masai giraffes Giraffa camelopardalis tippelskirchi is extremely female biased, particularly among newborns. Our results suggest that this might be a response to heavy illegal hunting and the continuous disturbance such activities cause on giraffes, as sex ratios were more female skewed in all age groups in areas […]
Factors affecting group size and vigilance behaviour of Maasai Giraffe (Giraffa Camelopardalis Tippelskirchi) in the Serengeti Ngorongoro Ecosystem, Tanzania
This study investigates factors affecting group sizes of Maasai giraffe (Giraffa camelopardalis tippelskirchi) in the Serengeti-Ngorongoro ecosystem, northern Tanzania. Various studies on giraffes have been conducted in the past, but none has investigated factors affecting giraffes’ group size and vigilance behavior in this vast ecosystem. As a result, I was motivated to investigate the following […]
Habitat availability, hunting or poaching: what affects distribution and density of large mammals in western Tanzanian woodlands?
Game reserves (GR) in Tanzania have been found to support similar or lower densities of large mammals compared with National parks (NP). But as these areas usually differ considerably not only in regard to management but also to environmental factors, we assessed the relative importance of vegetation cover, species-specific habitat preferences and legal (trophy hunting) […]
