  • A 20-year review of the status and distribution of African wild dogs (Lycaon pictus) in South Africa 
    Nicholson, Samantha K.; Marneweck, David G.; Lindsey, Peter Andrew; Marnewick, Kelly; Davies-Mostert, Harriet T. (Southern African Wildlife Management Association, 2020-02)
    South Africa is one of only seven countries with a viable population of African wild dogs (Lycaon pictus). The national population in 2017 was 372 adults and yearlings and comprised three subpopulations: 1) Kruger National ...
  • Food, family and female age affect reproduction and pup survival of African wild dogs 
    Marneweck, David G.; Druce, Dave J.; Somers, Michael J. (Springer, 2019-05)
    Understanding factors that affect the reproductive output and growth of a population of endangered carnivores is key to providing information for their effective conservation. Here, we assessed patterns in reproduction for ...
  • A novel technique for artificial pack formation in African wild dogs using odour familiarity 
    Marneweck, Courtney J.; Marchal, Antoine F.J.; Marneweck, David G.; Beverley, Grant; Davies-Mostert, Harriet T.; Parker, Dan M. (Southern African Wildlife Management Association, 2019)
    Reintroductions are recognized tools for species recovery. However, operations are costly, difficult to implement, and failures are common and not always understood. Their success for group-living species depends on ...
  • The relative role of intrinsic and extrinsic drivers in regulating population change and survival of African wild dogs (Lycaon pictus) 
    Marneweck, David G.; Druce, Dave J.; Cromsigt, Joris P.G.M.; Le Roux, Elizabeth; Somers, Michael J. (Springer, 2022-08)
    Evaluating how intrinsic (intraspecific density), extrinsic (interspecific density and prey density) and anthropogenic (management intervention) factors affect African wild dog (Lycaon pictus) population performance is key ...
  • Spatial heterogeneity facilitates carnivore coexistence 
    Davies, Andrew Byron; Tambling, Craig J.; Marneweck, David G.; Ranc, Nathan; Druce, Dave J.; Cromsigt, Joris P.G.M.; Le Roux, Elizabeth; Asner, Gregory P. (Ecological Society of America, 2021)
    Competitively dominant carnivore species can limit the population sizes and alter the behavior of inferior competitors. Established mechanisms that enable carnivore coexistence include spatial and temporal avoidance of ...
  • Spatial partitioning by a subordinate carnivore is mediated by conspecific overlap 
    Marneweck, C.; Marneweck, David G.; Van Schalkwyk, Ockert Louis; Beverley, G.; Davies-Mostert, Harriet T.; Parker, D.M. (Springer, 2019-11)
    There are several hypotheses that could explain territory size in mammals, including the resource dispersion hypothesis (RDH), the intruder pressure hypothesis (IPH), and the intraguild predation hypothesis (IGPH). In this ...
  • Temporal patterns of den use suggest polygamous mating patterns in an obligate monogamous mammal 
    Kotze, Robynne; Bennett, Nigel Charles; Cameron, Elissa Z.; Low de Vries, J.; Marneweck, David G.; Pirk, Christian Walter Werner; Dalerum, Fredrik (Elsevier, 2012)
    Mating systems in animal societies contain both social and genetic components. Deviations between these components may have important ramifications for our understanding of the evolution of animal reproductive strategies ...
