Aan de hand van wiskundige modellen en simulaties gingen we na of abrupte adaptionele regime shifts kunnen optreden in natuurlijke populaties. We onderzochten zowel de gevolgen van veranderingen in connectiviteit tussen populaties als gevolgen van de omzetting van habitattypes.
This thesis describes how the social-ecological system around the Mara wetlands has changed during the previous five decades. These wetlands are mainly fed by the Mara River, which has its sources in the Kenyan Mau Escarpment. After flowing through two worldfamous wildlife parks (Serengeti and Maasai Mara), it continues in the downstream Tanzanian Mara wetlands and finally flows out in Lake Victoria.
The major focus of this thesis is on how the riparian Wakenye people in Northwest Tanzania have adapted their livelihoods to the changing context.
