The Serengeti research is not
a WWCT project; instead it is part of a long-standing programme called The
Serengeti Biodiversity Programme, supported by the University
of British Columbia and University of Guelph
in Canada,
mostly with funding from the National Science and Engineering Research Council
of Canada. Andrew Kittle, Principle Investigator of WWCT is a part of this programme through his Phd
reseach with Dr. John Fryxell at the University
of Guelph.
The main focus of his Phd research
is ‘Carnivore co-existence’ through which he aims to better understand the
methods used by competing carnivore species to share time and space. Lions and
hyenas are the two major predators in the Serengeti system, responsible for an
estimated 85% of herbivore predation there (Sinclair et al 1995) and they are
also frequent rivals, competing over food resources both directly (fighting and
stealing kills) and indirectly (both utilizing the same prey species). This
project follows 5 lions from neighbouring prides and 5 hyenas from overlapping
and neighbouring clans fitted with GPS radio collars which record their exact
location every 2 hours. The collars were active for ~18 months and have now
been removed and data analysis is underway.
One of the key links between
the work in the Serengeti and our research here in Sri Lanka, is our interest in the
role of intra-guild competition in shaping carnivore behaviour and ecology. In Sri Lanka, the
leopard is the only large cat and the top predator and is free from this type
of competition. They do compete from time to time with bears over kills but
bears are omnivorous and not directly in competition. A closer approximation of
this type of competition here is with the fishing cat, especially in areas
where larger herbivores are absent, but this relationship is very
asymmetrical.
