Symbiotic ants as an alternative defense against giraffe herbivory in spinescent Acacia drepanolobium

We explore here the occurrence of aggressive ants in an apparently symbiotic relationship with the savanna tree Acacia drepanolobium and their effects on giraffe herbivory on the Athi-Kapiti Plains, Kenya. Trees taller than 1.3 m were more likely to be occupied by aggressive ants in the genus Crematogaster than were shorter trees. Ants were concentrated on shoot tips, the plant parts preferred by giraffes. Trees with relatively more foliage had more swarming ants than did trees with less foliage. The feeding behavior of individual

Factors affecting habitat use by Masai Giraffe (Giraffa camelopardalis tippelskirchi L) in Athi-Kapiti Plains ecosystem, Kenya

Increased human settlement, land use changes, loss of migration corridors, habitat loss and fragmentation have affected habitat use by Masai giraffe in Athi-Kapiti plains ecosystem. The purpose of the study was to assess the factors affecting habitat use by Masai giraffe (Giraffa camelopardalis tippelskirchi) in the Athi-Kapiti plains ecosystem and to generate information for giraffe sustainable conservation and management. The specific objectives of the study were to assess past and present giraffe population, assess the relative abundance of giraffe food
