Turner, Wendy C.; Periquet, Stephanie; Goelst, Claire E.; Vera, Kimberlie B.; Cameron, Elissa Z.; Alexander, Kathleen A.; Belant, Jerrold L.; Cloete, Claudine C.; Du Preez, Pierre; Getz, Wayne Marcus; Hetem, Robyn S.; Kamath, Pauline L.; Kasaona, Marthin K.; Mackenzie, Monique; Mendelsohn, John; Mfune, John K.E.; Muntifering, Jeff R.; Portas, Ruben; Scott, H. Ann; Strauss, W. Maartin; Versfeld, Wilferd; Wachter, Bettina; Wittemyer, George; Kilian, J. Werner (Elsevier, 2022-10)Proclaimed in 1907, Etosha National Park in northern Namibia is an iconic dryland system with a rich history of wildlife conservation and research. A recent research symposium on wildlife conservation in the Greater Etosha ...

Belton, L.E. (Lydia); Cameron, Elissa Z.; Dalerum, Fredrik (Springer, 2018-07)Rapid urban expansion has led to an increase in carnivores that live close to human dominated environments. Some carnivore species have successfully adapted to these novel conditions and taken advantage of opportunities ...

Van der Merwe, Ingrid; Tambling, Craig J.; Thorn, Michelle; Scott, Dawn M.; Yarnell, Richard W.; Green, Matthew; Cameron, Elissa Z.; Bateman, Philip W. (Zoological Society of Southern Africa, 2009-10)We used scat analysis to study the diet of two sympatric medium-sized carnivores: brown hyaena and black-backed jackal, in the NorthWest Province of South Africa. Seven major dietary categories were identified from the ...

Marneweck, David G.; Cameron, Elissa Z.; Ganswindt, Andre; Dalerum, Fredrik (Elsevier, 2015-01)It is now widely recognized that mating systems contain both social and genetic components, where social components describe patterns of social associations while genetic components reflect patterns of mating activities. ...
-
White, Angela M.; Cameron, Elissa Z. (Elsevier, 2008-08)Warthogs, Phacochoerus africanus, are an unusual ungulate. They are facultative cooperative breeders where females within the same population display both solitary and cooperative reproductive strategies. Warthogs require ...

Thorn, Michelle; Green, Matthew; Bateman, Philip W.; Cameron, Elissa Z.; Yarnell, Richard W.; Scott, Dawn M. (Southern African Wildlife Management Association, 2010-04)Many carnivores are difficult and labour-intensive to detect, often leading to prohibitively high effort and cost in large-scale surveys.However,such studies provide information that is important for effective management ...

Linklater, Wayne L.; Plotz, Roan D.; Kerley, Graham I. H.; Brashares, Justin S.; Lent, Peter C.; Cameron, Elissa Z.; Law, Peter R.; Hitchins, Peter M. (Cambridge University Press, 2010-01)No abstract available.

Gray, Meeghan E.; Cameron, Elissa Z. (Society for Reproduction and Fertility, 2010-01)The efficacy of contraceptive treatments has been extensively tested, and several formulations are effective at reducing fertility in a range of species. However, these formulations should minimally impact the behaviour ...

Periquet, Stephanie; Richardson, Peter; Cameron, Elissa Z.; Ganswindt, Andre; Belton, L.E. (Lydia); Loubser, Elize; Dalerum, Fredrik (Wiley, 2017-09)Living under predation risk may alter both behaviour and physiology of potential prey. In extreme cases, such alterations may have serious demographic consequences, and recent studies support that non-lethal effects of ...

Thorn, Michelle; Scott, Dawn M.; Green, Matthew; Bateman, Philip W.; Cameron, Elissa Z. (Southern African Wildlife Management Association, 2008-04)Conservation and management of brown hyaenas (Hyaena brunnea) is hampered by a lack of information on abundance and distribution, which is difficult and labour-intensive to obtain. However, occupancy surveys offer a ...

Estimating carnivoran diets using a combination of carcass observations and scats from GPS clusters Tambling, Craig J.; Laurence, S.D.; Bellan, S.E.; Cameron, Elissa Z.; Du Toit, Johan T.; Getz, Wayne Marcus (Wiley-Blackwell, 2012-02)Scat analysis is one of the most frequently used methods to assess carnivoran diets, and global positioning system (GPS) cluster methods are increasingly being used to locate feeding sites for large carnivorans. However, ...

De Vries, J.L.; Pirk, Christian Walter Werner; Bateman, Philip W.; Cameron, Elissa Z.; Dalerum, Fredrik (Zoological Society of Southern Africa, 2011-04)The aardwolf, Proteles cristata, is a highly specialized myrmecophagous carnivore that feeds almost exclusively on termites of the genus Trinervitermes. Here we report data from an ongoing analysis of aardwolf diet, where ...
-
Cameron, Elissa Z.; Linklater, Wayne L. (Royal Society, 2007-08)Adaptive theory predicts that mothers would be advantaged by adjusting the sex ratio of their offspring in relation to their offspring's future reproductive success. Studies investigating sex ratio variation in mammals ...
-
Dalerum, Fredrik; Cameron, Elissa Z.; Kunkel, Kyran; Somers, Michael J. (Springer, 2012-02)The importance of species diversity for ecosystem function has emerged as a key question for conservation biology. Recently, there has been a shift from examining the role of species richness in isolation towards understanding ...
-
Thorn, Michelle; Green, Matthew; Mark, Keith; Marnewick, Kelly; Bateman, Philip W.; Cameron, Elissa Z.; Scott, Dawn M. (Cambridge University Press, 2011)Accurate assessment of carnivore population status is frequently hindered by insufficient distribution data. For northern South Africa we address this deficit by mapping new records from landscape-scale sign ...
-
Tambling, Craig J.; Cameron, Elissa Z.; Du Toit, Johan T.; Getz, Wayne Marcus (Wildlife Society, 2010-04)Knowledge of the range, behavior, and feeding habits of large carnivores is fundamental to their successful conservation. Traditionally, the best method to obtain feeding data is through continuous observation, which is ...
-
Gray, Meeghan E.; Thain, David S.; Cameron, Elissa Z.; Miller, Lowell A. (CSIRO, 2010-10)CONTEXT: Contraception is increasingly used as a management technique to reduce fertility in wildlife populations, but the feasibility of contraceptive formulations has been limited until recently as they have required ...
-
Non-invasive assessment of adrenocortical function in captive Nile crocodiles (Crocodylus niloticus) Ganswindt, Stefanie Birgit; Myburgh, Jan G.; Cameron, Elissa Z.; Ganswindt, Andre (Elsevier, 2014-11)The occurrence of stress-inducing factors in captive crocodilians is a concern, since chronic stress can negatively affect animal health and reproduction, and hence production. Monitoring stress in wild crocodiles could ...

Ncube, Hlengisizwe; Duncan, Patrick; Grange, Sophie; Cameron, Elissa Z.; Barnier, Florian; Ganswindt, Andre (Elsevier, 2011-07)Regulative endocrine mechanisms influence the reproductive behaviour and success of mammals, but they have been studied predominantly in domestic and captive animals. The study aims at describing the pattern of faecal ...

Rainer, Sharna R.; Cameron, Elissa Z.; Edwards, Amy M.; Bennett, Nigel Charles; Thomas, Hannah Grace; Swanepoel, Daniel (Oxford University Press, 2023)Sperm competition results from postcopulatory continuation of male–male competition for paternity. The level of sperm competition is predicted to be highest in species with greater polyandry and weakest in monogamous ...
