  • Jettisoning ballast or fuel? Caudal autotomy and locomotory energetics of the Cape dwarf gecko Lygodactylus capensis (Gekkonidae) 
    Fleming, Patricia A.; Verburgt, Luke; Scantlebury, Michael; Medger, Katarina; Bateman, Philip W. (University of Chicago Press, 2009-09)
    Many lizard species will shed their tail as a defensive response (e.g., to escape a putative predator or aggressive conspecific). This caudal autotomy incurs a number of costs as a result of loss of the tail itself, ...

  • King penguin brooding and defending a sub-Antarctic skua chick 
    Oosthuizen, Wessel Christiaan; De Bruyn, P.J. Nico (Springer, 2009)
    Interspecific parental care is rare, conveys no ultimate evolutionary advantage, and is usually attributed to reproductive errors in species with analogous habitat, behaviour and diet. We report on interspecific parental ...

    Reisinger, Ryan Rudolf; Beukes, Charlene; Hoelzel, A. Rus; De Bruyn, P.J. Nico (Oxford University Press, 2017-05)
    Social structure is a core element of population biology, influenced by intrinsic and environmental factors. Intra-taxon comparisons of social organization are useful in elucidating the role of such ecological determinants ...

    Knowledge about how pastoralism and kraaling may contribute to desired global objectives, such as soil fertility, is in danger of being lost. We tested whether short duration kraaling increases soil fertility across various ...
  • Landing preference and reproduction of Rhopalosiphum padi (Hemiptera : Aphididae) in the laboratory on three maize, potato, and wheat cultivars 
    Schroder, Michelle L.; Glinwood, R.; Ignell, R.; Kruger, Kerstin (Oxford University Press, 2015-05)
    The bird cherry-oat aphid Rhopalosiphum padi (L.) transmits the nonpersistent Potato virus Y (PVY) to seed potatoes. Planting a nonvirus host plant around the main crop can reduce PVY incidence, because aphids tend to land ...
  • Landscape determinants of fine-scale genetic structure of a small rodent in a heterogeneous landscape (Hluhluwe-iMfolozi Park, South Africa) 
    Russo, Isa-Rita M.; Sole, Catherine L.; Barbarto, Mario; Von Bramann, Ullrich; Bruford, Michael W. (Nature Publishing Group, 2016-07-13)
    Small mammals provide ecosystem services, acting, for example, as pollinators and seed dispersers. In addition, they are also disease reservoirs that can be detrimental to human health and they can also act as crop pests. ...
  • Landscape heterogeneity and woody encroachment decrease mesocarnivore scavenging in a savanna agroecosystem 
    Lima, Kyle A.; Stevens, Nicola; Wisely, Samantha M.; Fletcher, Robert J., Jr.; Monadjem, Ara; Austin, James D.; Mahlaba, Themb'alilahlwa; McCleery, Robert A. (Elsevier, 2021-09)
    Increased agricultural intensification and extensive woody plant encroachment are having widespread effects on the functioning of grass-dominated systems at multiple spatial scales. Yet there is little understanding of how ...
  • Landscape heterogeneity shapes taxonomic diversity of non-breeding birds across fragmented savanna landscapes 
    Ke, Alison; Sibiya, Muzi D.; Reynolds, Chevonne; McCleery, Robert A.; Monadjem, Ara; Fletcher Jr, Robert J. (Springer, 2018-08)
    There is an ongoing need to integrate agricultural production with wildlife conservation to maintain biodiversity, especially in developing countries. The landscape heterogeneity hypothesis identifies a potential means for ...
  • Landscape level effects of lion presence (Panthera leo) on two contrasting prey species 
    Chizzola, Maddalena; Belton, L.E. (Lydia); Ganswindt, Andre; Greco, Ilaria; Hall, Grant; Swanepoel, Lourens; Dalerum, Fredrik (Frontiers Media, 2018-11-27)
    Due to the strong individual cost of being predated, potential prey species alter their behavior and physiology in response to predation risk. Such alterations may cause major indirect consequences on prey populations ...
  • Landscape vegetation productivity influences population dynamics of key pests in small avocado farms in Kenya 
    Toukem, Nadia Karelle; Yusuf, Abdullahi Ahmed; Dubois, Thomas; Abdel-Rahman, Elfatih M.; Adan, Marian Salim; Mohamed, Samira A. (MDPI Publishing, 2020-07-09)

    Jacobs, Paul Juan; Oosthuizen, Maria Kathleen (Elsevier, 2021-04)
    Behavioural lateralization, the differential use one side of the body, and/or the bilateral use of sensory organs or limbs, is common in many vertebrates. One way in which behavioural lateralization can be detected in ...
