Few studies have investigated how free-ranging wild herbivores adjust their food intake rate and nutrient gains during the dry season. Our study focused on the largest extant grazer, the white rhinoceros (Ceratotherium simum Burchell 1817). Field measurements were made on changes in bite mass, bi...

How a mega-grazer copes with the dry season: Food and nutrient intake rates by white rhinoceros in the wild
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 Nin˜ o-Southern Oscillation (ENSO), using
the Southern Oscil...

Accurate estimation of wildlife population size is central to effective management and conservation but is notoriously difficult for rare and cryptic carnivores. Mark-recapture methods can reliably estimate the abundance of large carnivores but are sensitive to departures from the assumption of e...

Application of mark-recapture methods to lions: Satisfying assumptions by using covariates to explain heterogeneity
Effective management and conservation of wildlife populations require reliable estimates of population size, which can be difficult and costly to obtain. We evaluated how precision in estimates of herd size and abundance varies with sample size and strip width using two field surveys and bootstra...

This paper examines the effects of wildlife tourism-based payments for ecosystem services (PES) on poverty, wealth inequality and the livelihoods of herders in the Maasai Mara Ecosystem in south-western Kenya. It uses the case of Olare Orok Conservancy PES programme in which pastoral landowners h...
