  • 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 ...
  • African wild dogs : genetic viability of translocated populations across South Africa 
    Tensen, Laura; Jansen van Vuuren, Bettine; Du Plessis, Cole; Marneweck, David G. (Elsevier, 2019-06)
    South Africa holds a viable population of the endangered African wild dog (Lycaon pictus), with almost 500 individuals divided into (1) an unmanaged population in the Kruger National Park (KNP), (2) a free-roaming population, ...
  • Environmental controls on African herbivore responses to landscapes of fear 
    Davies, Andrew Byron; Cromsigt, Joris P.G.M.; Tambling, Craig J.; Le Roux, Elizabeth; Vaughn, Nicholas; Druce, Dave J.; Marneweck, David G.; Asner, Gregory P. (Wiley, 2021-02)
    Herbivores balance forage acquisition with the need to avoid predation, often leading to tradeoffs between forgoing resources to avoid areas of high predation risk, or tolerating increased risk in exchange for improved ...
  • Factors affecting the success of artificial pack formation in an endangered, social carnivore : the African wild dog 
    Marneweck, Courtney; Becker, P.A.; Beverley, G.; Davies-Mostert, Harriet T.; Du Plessis, C.; Forssman, K.R. (Katherine); Graf, J.; Gusset, M.; Hofmeyr, M.; Kelly, C.; Kilian, P.J.; Marchal, A.F.J.; Marneweck, David G.; Marnewick, K.; Owen, C.; Postiglione, G.; Slotow, R.; Somers, Michael J.; Szykman, G.M.; Van Dyk, G.; Whittington-Jones, B.; Parker, Daniel M. (Wiley, 2019-10)
    Social integration is an important factor when reintroducing group‐living species, but examples of the formation of social groups before reintroduction are largely lacking. African wild dogs Lycaon pictus are endangered, ...
  • Fence management and time since pack formation influence African wild dog escapes from protected areas in South Africa 
    Stone, David W.; Kelly, Chris; Marneweck, David G.; Druce, Dave J.; Hopcraft, J. Grant C.; Marneweck, Courtney J. (Elsevier, 2022-12)
    In human-dominated and highly fragmented landscapes, keeping wildlife within reserve boundaries is vital for conservation success. In South Africa, fences are a widely employed conservation management tool for protected ...
  • 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 ...
  • Reproductive state influences the degree of risk tolerance for a seasonally breeding mesopredator 
    Marneweck, Courtney J.; Van Schalkwyk, Ockert Louis; Marneweck, David G.; Beverley, Grant; Davies-Mostert, Harriet T.; Parker, Daniel M. (Oxford University Press, 2021-07)
    The risk of predation can alter the way animals perceive costs and benefits in their environment, on which foraging decisions are made. To maximize fitness, animals with offspring show the most pronounced alteration in ...
  • 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 ...
  • Top–down limits on prey populations may be more severe in larger prey species, despite having fewer predators 
    Le Roux, Elizabeth; Marneweck, David G.; Clinning, Geoff; Druce, Dave J.; Kerley, Graham I.H.; Cromsigt, Joris P.G.M. (Wiley, 2019-06)
    Variation in the vulnerability of herbivore prey to predation is linked to body size, yet whether this relationship is size‐nested or size‐partitioned remains debated. If size‐partitioned, predators would be focused on ...

    Williams, Samual T.; Collinson, Wendy J.; Patterson-Abrolat, Claire; Marneweck, David G.; Swanepoel, Lourens H. (Peer J, 2019-03-29)
    As the global road network expands, roads pose an emerging threat to wildlife populations. One way in which roads can affect wildlife is wildlife-vehicle collisions, which can be a significant cause of mortality through ...
