Aspects of the spatial and behavioural ecology of Hippopotamus amphibious in the Saint Lucia Estuary, KwaZulu-Natal, South Africa

Author: Prinsloo, Alexa Simone Date: 2016 The common hippopotamus (Hippopotamus amphibius) is endemic to Africa but threatened by range restriction, exploitation and competition with humans and domestic livestock for access to critical resources such as fresh water and grazing. ... Read more
Behavioural and isotope ecology of marine-foraging chacma baboons (Papio ursinus) on the Cape Peninsula, South Africa

Author: Lewis, Matthew Charles Date: 2015 The dominant vegetation type on the Cape Peninsula, South Africa, is an oligotrophic shrub land that supports low numbers of medium-sized and large terrestrial mammals. Of these, only the adaptable and dextrous chacma baboon (Papio ursinus) ... Read more
Conservation ecology of the Cape clawless otter, Aonyx capensis, in an urban environment

Author: Okes, Nicola Catherine Date: 2017 Coastal cities have impacted negatively on freshwater and marine ecosystems - primarily through habitat loss, fragmentation and pollution. Globally, it has been found that otter's dependence on these ecosystems exposes them to a myriad of ... Read more
How attractive is the girl next door? An assessment of spatial mate acquisition and paternity in the solitary Cape dune mole-Rat, Bathyergus suillus

Author: Bray, Timothy C ; Bloomer, Paulette ; O'Riain, M Justin ; Bennett, Nigel C Date: 2012 Behavioural observations of reproduction and mate choice in wild fossorial rodents are extremely limited and consequently indirect methods are typically used to infer mating strategies. We use a combination of morphological, reproductive, ... Read more c b
In pursuit of a panacea: mitigating human-baboon conflict in the Cape Peninsula, South Africa

Author: Kaplan, Bentley Date: 2013 With its unparalleled growth and distribution, the human species is increasingly conflicting with wildlife over crops, livestock and even human life as it infringes on natural habitat. In the Cape Peninsula, South Africa, urbanisation has ... Read more
Landscape requirements of a primate population in a human-dominated environment

Author: Hoffman, Tali ; O'Riain, M Justin Date: 2012 INTRODUCTION: As urban and rural land development become widespread features of the global landscape so an understanding of the landscape requirements of displaced and isolated wildlife species becomes increasingly important for conservation ...

Predictors of white shark Carcharodon carcharias presence at two recreational beaches in a major metropole

Author: Loosen, Kristina Date: 2017 The presence of white sharks Carcharodon carcharias in False Bay, South Africa follows a clear seasonal cycle. In the austral winter months, white sharks aggregate around Seal Island with female sharks in particular moving to the inshore areas ... Read more
Residency, habitat use and sexual segregation of white sharks, Carcharodon carcharias in False Bay, South Africa

Author: Kock, Alison ; O'Riain, M Justin ; Mauff, Katya ; Meÿer, Michael ; Kotze, Deon ; Griffiths, Charles Date: 2013 White sharks ( Carcharodon carcharias ) are threatened apex predators and identification of their critical habitats and how these are used are essential to ensuring improved local and ultimately global white shark protection. In this study ... Read more c b
Sperm structure and motility in the eusocial naked mole-rat, Heterocephalus glaber: a case of degenerative orthogenesis in the absence of sperm competition?

Author: Van der Horst, Gerhard ; Maree, Liana ; Kotze, Sanet ; O'Riain, M Justin Date: 2011 BACKGROUND:We have studied sperm structure and motility in a eusocial rodent where reproduction is typically restricted to a single male and behaviourally dominant queen. Males rarely compete for access to the queen during her estrus cycle, ... Read more c b
The trophic dynamics of the broadnose sevengill shark (Notorynchus cepedianus) in False Bay, South Africa, using multiple tissue stable isotope analysis

Author: De Necker, Leigh Date: 2017 Despite their important ecological role, there is limited quantitative information on the trophic ecology of large, apex predator sharks. This is largely a consequence of their occupying naturally low population densities, being highly mobile ... Read more
Understanding the black-backed jackal

Author: Nattrass, Nicoli ; Conradie, Beatrice ; Drouilly, Marine ; O'Riain, M Justin Date: Mar 2017 This paper reviews what we know about black-backed jackal ecology, drawing implications for managing human-wildlife conflict with this species. We review the research literature on the black-backed jackals in the context of other African ... Read more
Wildlife health in human-modified landscapes: epidemiology of tick-borne pathogens affecting black-backed jackals and caracals

Author: Viljoen, Storme Date: 2017 Despite the importance of disease as a wildlife management challenge, baseline research on the epidemiology of pathogens occurring in wildlife populations within both rural and urban landscapes has received little attention to date. The aim ... Read more
