Ecology Of African Grazing And Browsing Mammals

Africa is the earth’s second largest continent, comprising 20% of its surface. Largely tropical, Africa extends as well into temperate zones to 37°N and 35°S. Eastern and southern Africa display steep elevation gradients due to the prevalence there of volcanic orogeny and rifting (29). Local landscapes are distinguished by substantial geological heterogeneity, dissected land forms, and resultant steep gradients of precipitation and vegetation. The consequent pronounced fragmentation of habitats and sharp juxtaposition of distinct vegetation types, combined with climatic oscillations

Digestive tract pathology of captive giraffe (Giraffa Camelopardalis). A unifying hypothesis

Captive giraffe (Giraffa Camelopardalis) are affected by four major pathological conditions linked to their nutrition: (1) the so-called “peracute mortality syndrome” with complete absence and serious atrophy of body fat stores, (2) phytobezoars, i.e. Fibrous conglomerates  of plant material, in the omasum and abomasums (3) rumen acidosis or (4) partial loss of dorsal ruminal papillation. We hypothesise that all four conditions can be explained by the fact that the giraffe, like other browsing ruminants, is not adapted to grass or
