Patterns of Variation of Herbivore Assemblages at Nairobi National Park, Kenya, 1990-2008
Wildlife, especially mammals populations dynamics in many conservation areas are influenced by ecosystem processes and increasingly by climate change. Generally, cyclic population dynamics is relatively common among small mammals, especially in high latitudes but is not yet established among many African savanna ungulates. Habitat fragmentation and loss propagated by anthropogenic activities are responsible for the […]
The use of archeological and ethnographical information to supplement the historical record of the distribution of large mammalian herbivores in South Africa
The introduction of animal taxa to areas where they do not naturally occur has the potential to damage severely the native fauna and flora. Introductions, both accidental and intentional, to Australia, New Zealand, Marion Island and other oceanic islands provide spectacular examples of this. Non-native mammalian herbivores often become invasive in the absence of their […]
Feed Selection and Digestibility by Captive Giraffe
A digestion trial with subsequent examination of feed selection was conducted using two captive giraffe fed four feedstuffs. Apparent digestibility coefficients were relatively high, indicating that the animals were efficiently utilizing the feedstuffs. However, values could be affected by the possible ingestion of soil containing acid‐insoluble ash. A high fiber pelleted feed was eaten in […]
Seasonal density estimates of common large herbivores in Hwange National Park, Zimbabwe
The monitoring of ecosystem processes and states is a critical step in the management of protected areas. It allows for the assessment of the success or failure of practices ranging from ‘laissez-faire’ to strong hands-on policies. Much effort is for instance devoted to the monitoring of wildlife abundance, particularly when associated with large ecological influence […]
Structure and composition of Acacia xanthophloea woodland in Lake Nakuru National Park, Kenya
The woody vegetation of Lake Nakuru National Park occurs along rivers, lakeshores and flood plains. Four different sites within the Acacia xanthophloea woodlands were selected for the study. Vegetation structure was not significantly different in the four woodlands used for the study, but these sites differed in the relative density of Acacia trees. Regeneration of […]
