| dc.description.abstract | The study has two main component : population ecology and pasture use These are fused together for probable implications of density-dependent regulation
on wildebeest and cattle populations in the study area.
Asa basis to this study, the vegetation and ecology
of pastures in the study area discussed. Rainfall is
considered as the main underlying factor in determining
the available food resource and animal movements in both
the dry and wet season ecosystems, Under such circumstances.
rainfall records over a 5 year period air compared
and these records suggest that possibly 1973 was a drier
year. The implications of these climatic variations are
discussed in relation to pasture use and animal density
in the basin.
The numbers of wildebeest and cattle populations in
the basin and methods used for estimation of numbers are
discussed. Emphasis is however. mainly on wildebeest and
data on age determination, mortality,reproduction and life table are discussed | en |
