Male-Biased Partial Migration in a Giraffe Population
Partial migration is a common movement phenomenon in ungulates, wherein part of the population remains resident while another portion of the population transitions to spatially or ecologically distinct seasonal ranges. Although widely documented, the causes of variation in movement strategies and their potential demographic consequences are not well-understood. Here, we used GPS telemetry data and […]
Cameras replace human observers in multi-species aerial counts in Murchison Falls, Uganda
Wildlife counts in Africa and elsewhere are often implemented using light aircraft with ‘rear-seat-observer’ (RSO) counting crews. Previous research has indicated that RSOs often fail to detect animals, and that population estimates are therefore biased. We conducted aerial wildlife surveys in Murchison Falls Protected Area, Uganda, in which we replaced RSOs with high-definition ‘oblique camera […]
Genetic Architecture Detected by Microsatellite Screening of the Rothschild’s Giraffe (Giraffa camelopardalis rothschildi) Population in Murchison Falls National Park
There are six recognized populations of Rothschild’s giraffe (Giraffa camelopardalis rothschildi) protected in Uganda and Kenya. Two populations in Uganda are at Murchison Falls National Park and Kidepo Valley National Park. Four populations in Kenya are at Lake Nakuru National Park, Ruma National Park, Giraffe Manor, and Yoder Flower Farm. The Kidepo Valley population in […]
