    Adult male southern elephant seals instrumented in 2000 on King George Island (n = 13), travelled both to the north (n = 2) and to the east (n = 6) of the Antarctic Peninsula. Five males remained within 500 km of the island ...
  • Cross-seasonal foraging site fidelity of subantarctic fur seals : implications for marine conservation areas 
    Wege, Mia; Tosh, Cheryl A.; De Bruyn, P.J. Nico; Bester, Marthan Nieuwoudt (Inter-Research, 2016-07)
    Marine top-predators show fidelity to foraging areas with predictable high-quality food patches. Areas of predictable prey yield are of conservation importance and telemetry data aid in identifying such areas. This study ...

    McIntyre, Trevor; Bornemann, Horst; Plotz, Joachim; Tosh, Cheryl A.; Bester, Marthan Nieuwoudt (Cambridge University Press, 2012)
    We describe the habitat use of 22 male southern elephant seals (Mirounga leonina) satellite tagged at Marion Island between 2004 and 2008. While a few areas of increased utilization appeared to be associated with areas ...
  • Dispersal and dispersion of southern elephant seals in the Kerguelen province, Southern Ocean

    Southern elephant seals Mirounga leonina within the Kerguelen province disperse between Marion Island (MI), Iles Crozet (IC) and Iles Kerguelen (IK) despite the high site fidelity characteristic of this species. From ...
  • First confirmed record of a leucistic Antarctic fur seal pup born outside the Scotia Arc Islands 
    Wege, Mia; Postma, Martin; Tosh, Cheryl A.; De Bruyn, P.J. Nico; Bester, Marthan Nieuwoudt (Springer, 2015-04)
    A leucistic Antarctic fur seal (Arctocephalus gazella) pup was born on subantarctic Marion Island during the austral summer of 2010/2011. This is the first confirmed record of a leucistic fur seal pup born outside ...
  • Habitat modelling of tracking data from multiple marine predators identifies important areas in the Southern Indian Ocean 
    Reisinger, Ryan Rudolf; Raymond, Ben; Hindell, Mark A.; Bester, Marthan Nieuwoudt; Crawford, Robert J.M.; Davies, Delia; De Bruyn, P.J. Nico; Dilley, Ben J.; Kirkman, Stephen P.; Makhado, Azwianewi B.; Ryan, Peter G.; Schoombie, Stefan; Stevens, Kim; Sumner, Michael D.; Tosh, Cheryl A.; Wege, Mia; Whitehead, Thomas Otto; Wotherspoon, Simon; Pistorius, Pierre Anton (Wiley, 2018-04)
    AIM : The distribution of marine predators is driven by the distribution and abundance of their prey; areas preferred by multiple marine predator species should therefore indicate areas of ecological significance. The ...
  • Home range and habitat use of roan antelope Hippotragus equinus in Northern Botswana 
    Havemann, Carl Peter; Retief, Tarryn Anne; Collins, Kai; Fynn, R.W.S.; Tosh, Cheryl A.; De Bruyn, P.J. Nico (Elsevier, 2022-01)
    Studies investigating animal movement and habitat use are essential for wildlife management and conservation. Northern Botswana represents some of the least modified landscapes in Africa. Studying the seasonal habitat use ...
  • Inter-population differences in diving behaviour of adult male southern elephant seals (Mirounga leonina) 
    James, B.S. (Bridget); McIntyre, Trevor; Tosh, Cheryl A.; Bornemann, Horst; Plotz, Joachim; Bester, Marthan Nieuwoudt (Springer, 2012-11)
    Access to different environments may lead to inter-population behavioural changes within a species that allow populations to exploit their immediate environments. Elephant seals from Marion Island (MI) and King ...
  • Marine Mammal Programme at the Prince Edward Islands : 38 years of research 
    Bester, Marthan Nieuwoudt; De Bruyn, P.J. Nico; Oosthuizen, Wessel Christiaan; Tosh, Cheryl A.; McIntyre, Trevor; Reisinger, Ryan Rudolf; Postma, Martin; Van der Merwe, Derek S.; Wege, Mia (Taylor & Francis, 2011)
    The Marine Mammal Programme (MMP) conducts research on pinnipeds and killer whales Orcinus orca at Marion Island, Prince Edward Islands, under the auspices of the Mammal Research Institute, Department of Zoology and ...
  • Mass mortality of adult male subantarctic fur seals : are alien mice the culprits? 
    De Bruyn, P.J. Nico; Bastos, Armanda D.S.; Eadie, Candice; Tosh, Cheryl A.; Bester, Marthan Nieuwoudt (Public Library of Science, 2008-11)
    BACKGROUND: Mass mortalities of marine mammals due to infectious agents are increasingly reported. However, in contrast to previous die-offs, which were indiscriminate with respect to sex and age, here we report a land-based ...
  • The ontogeny of at-sea behaviour in male southern elephant seals (Mirounga leonina) at Marion Island 
    Lasch, Kiara G.; Tosh, Cheryl A.; Bester, Marthan N.; De Bruyn, P.J. Nico (2023-11-22, 2023-01)
    Megafauna, such as southern elephant seals (SESs) (Mirounga leonina, Linn.), forage in diverse, seemingly limitless habitats. In pelagic settings, their behaviour is more likely to be limited by physiological ability and ...
  • Prevalence of allosuckling behaviour in Subantarctic fur seal pups 
    De Bruyn, P.J. Nico; Cameron, Elissa Z.; Tosh, Cheryl A.; Oosthuizen, Wessel Christiaan; Reisinger, Ryan Rudolf; Mufanadzo, N. Thomas; Phalanndwa, Mashudu V.; Postma, Martin; Wege, Mia; Van der Merwe, Derek S.; Bester, Marthan Nieuwoudt (Elsevier, 2010-01)
    Non-offspring maternal care should be rare due to the high costs of raising offspring, particularly lactation, but nonetheless occurs in a variety of taxa. Misguided parental care, associated with recognition errors and/or ...
