Not all ants are equal: obligate acacia ants provide different levels of protection against mega-herbivores
In obligate ant–plant mutualisms, the asymmetric engagement of a single plant species with multiple ant species provides the opportunity for partners to vary in their behaviour. Variation in behaviour has implications for the interactions with third-party species such as herbivores. This study assessed the effect of obligate ant mutualists (Crematogaster mimosae, Crematogaster nigriceps and Tetraponera […]

The impacts of elephant, giraffe and fire upon the Acacia tortilis woodlands of the Serengeti
The reduction in canopy cover of the Seronera woodlands since the mid- 1960s can be largely attributed to the destruction of mature Acacia tortilis trees by elephants. The development of the tree regeneration that has colonized the gaps in the mature canopy is being suppressed by giraffe browsing and periodic burning. A simple model is […]
Food habits of giraffe in Tsavo National Park, Kenya
In the context of a broader ecological investigation, food habits of giraffe were studied in Tsavo National Park (East). The only method employed was direct observation of feeding animals in the field. Each instance in which one animal fed on one individual plant was counted as one food record for this plant species; 4025 records […]
