Efforts going to the dogs? Evaluating attempts to re-introduce endangered wild dogs in South Africa
Markus Gusset,Markus Gusset,Sadie J. Ryan,Markus Hofmeyr,Gus Van Dyk,Harriet T. Davies-Mostert,Harriet T. Davies-Mostert,Jan A. Graf,Cailey R. Owen,Micaela Szykman,Micaela Szykman,David W. Macdonald,Steven L. Monfort,David E. Wildt,Anthony H. Maddock,M. Gus L. Mills,Rob Slotow,Michael J. Somers +17 more
TL;DR: In this paper, the authors evaluated one of the most extensive efforts to date to re-introduce an endangered species: attempts to establish an actively managed meta-population of African wild dogs Lycaon pictus in South Africa.
Journal ArticleDOI
Translocating lions into an inbred lion population in the Hluhluwe‐iMfolozi Park, South Africa
Martina Trinkel,Martina Trinkel,Niall D. Ferguson,Niall D. Ferguson,A.P. Reid,C. Reid,Michael J. Somers,L. Turelli,Jan A. Graf,Micaela Szykman,Micaela Szykman,Dave Cooper,P. Haverman,Gerald Kastberger,Craig Packer,Rob Slotow +15 more
TL;DR: It is possible to infuse new genes rapidly and successfully into a small, isolated lion population and such translocations may become an important adaptive management tool as lion populations become increasingly fragmented.
Journal ArticleDOI
Dynamics of a small re-introduced population of wild dogs over 25 years: Allee effects and the implications of sociality for endangered species’ recovery
Michael J. Somers,Jan A. Graf,Micaela Szykman,Micaela Szykman,Rob Slotow,Markus Gusset,Markus Gusset +6 more
TL;DR: How aspects of a species’ social behaviour can influence the vulnerability of small populations to extinction is demonstrated and illustrates the profound implications of sociality for endangeredspecies’ recovery.
Journal ArticleDOI
Rates and causes of mortality in Endangered African wild dogs Lycaon pictus : lessons for management and monitoring
Rosie Woodroffe,Harriet T. Davies-Mostert,Joshua R. Ginsberg,Jan A. Graf,Kellie A. Leigh,Kim McCreery,Robert Robbins,Gus Mills,Alistair Pole,Gregory S. A. Rasmussen,Michael J. Somers,Micaela Szykman +11 more
TL;DR: Although the analyses identified no new threats beyond those highlighted in a 1997 range-wide Action Plan, they suggest that local plans will be valuable to target conservation activities more precisely.
Journal ArticleDOI
Space use of African wild dogs in relation to other large carnivores.
Angela M. Darnell,Jan A. Graf,Michael J. Somers,Rob Slotow,Micaela Szykman Gunther,Micaela Szykman Gunther +5 more
TL;DR: Understanding that larger carnivores affect the movements and space use of other carnivores is important for managing current small and fragmented carnivore populations, especially as reintroductions and translocations are essential tools used for the survival of endangered species, as with African wild dogs.
