We tested the hypothesis that ungulates time and synchronize births to match gestation and lactation with peak food availability and quality in seasonal environments, using ground counts of topi and warthog conducted over 174 months (July 1989–December 2003) in the Mara–Serengeti ecosystem. Durin...

Understanding long-term climatic variability is basic to wise management and conservation of biodiversity. We analysed temporal variations in the local rainfall, temperature, Normalized Difference Vegetation Index and the hemispheric El Niño-Southern Oscillation (ENSO), using the Southern Oscilla...

1. Rainfall is the prime climatic factor underpinning the dynamics of African savanna ungulates,but no study has analysed its influence on the abundance of these ungulates at monthly to multiannual time scales. 2. We report relationships between rainfall and changes in age- and sex-structured ...
