  1. The incidence of torpor in winter and summer in the Angolan free-tailed bat, <em>Mops condylurus</em> (Microchiroptera: Molossidae), in a subtropical environment, Mpumulanga, South Africa

    The incidence of torpor in winter and summer in the Angolan free-tailed bat, <em>Mops condylurus</em> (Microchiroptera: Molossidae), in a subtropical environment, Mpumulanga, South Africa

    Item type: Journal Article • Journal: African Zoology
    The incidence of torpor during summer and winter in response to cold exposure in Mops condylurus was studied in a subtropical environment. Body temperature changes under natural roosting conditions during winter and summer were monitored using bats fitted with temperature-sensitive...
  2. Can behaviour buffer the impacts of climate change on an arid-zone bird?

    Can behaviour buffer the impacts of climate change on an arid-zone bird?

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Behavioural thermoregulation, particularly the use of cool microclimates, is one method by which organisms could avoid the worst effects of climate warming. However, retreat into cool microsites, e.g. shady vegetation or burrows, may carry important lost-opportunity costs. These could include...
  3. Elevated temperatures drive fine-scale patterns of habitat use in a savanna bird community

    Elevated temperatures drive fine-scale patterns of habitat use in a savanna bird community

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Many animals use thermally buffered microhabitats, e.g. patches of shade within trees, to avoid temperature extremes. These ‘thermal refugia’ may mediate the impact of climate change on animals. Predicting how species and communities will respond to rising temperatures therefore requires...
  4. Diet and time-activity budget of White-backed Mousebirds <em>Colius colius</em> in south-western South Africa

    Diet and time-activity budget of White-backed Mousebirds <em>Colius colius</em> in south-western South Africa

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Mousebirds (Coliiformes) are unusual in having an exclusively vegetarian diet that includes substantial foliage and by using huddling and sunning to assist thermoregulation. Although previous studies have identified plant species and plant parts consumed by mousebirds, the relative importance of...
  5. Variation in the daily activity, movement and refugia of Critically Endangered geometric tortoises, <em>Psammobates geometricus</em>, in autumn and spring

    Variation in the daily activity, movement and refugia of Critically Endangered geometric tortoises, <em>Psammobates geometricus</em>, in autumn and spring

    Item type: Journal Article • Journal: African Journal of Herpetology
    To help assess habitat requirements of Critically Endangered geometric tortoises, we used thread-trailing to measure daily activity, movements and refugia of adult Psammobates geometricus in autumn and spring 2002. We found strong differences between seasons, and effects of weather, individuals...
  6. The energetic significance of communal roosting and insulated roost nests in a small arid-zone passerine<xref ref-type="fn" rid="FN0000"/>

    The energetic significance of communal roosting and insulated roost nests in a small arid-zone passerine<xref ref-type="fn" rid="FN0000"/>

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Small endotherms have evolved behavioural mechanisms for reducing rest-phase energy expenditure, which reduce the likelihood of mismatches between energy supply and demand during periods of cold weather and/or food scarcity. Although the energetic consequences of communal roosting and the use...
