  1. Seasonal effects on digging activity and burrow architecture in the Cape dune mole-rat, <em>Bathyergus suillus</em> (Rodentia: Bathyergidae)

    Seasonal effects on digging activity and burrow architecture in the Cape dune mole-rat, <em>Bathyergus suillus</em> (Rodentia: Bathyergidae)

    Item type: Journal Article • Journal: African Zoology
    Most polygynous male mammals exhibit little or no parental care or involvement raising young. Instead, they invest indirectly in their own morphological and physiological attributes which enhance their chance of reproduction. Such secondary morphological sex traits may contribute to differences...
  2. Influences of food quality and quantity on the male reproductive organs of a seasonally breeding rodent, the pouched mouse
(<em>Saccostomus campestris</em>), from a seasonal but unpredictable environment

    Influences of food quality and quantity on the male reproductive organs of a seasonally breeding rodent, the pouched mouse (<em>Saccostomus campestris</em>), from a seasonal but unpredictable environment

    Item type: Journal Article • Journal: African Zoology
    Reproduction in the pouched mouse (Saccostomus campestris) is inhibited in winter in the field and this seasonality is not controlled by photoperiod alone. The present study examines the hypothesis that reproduction in the pouched mouse is opportunistic (sensu Bronson 1989)...
  3. Metabolic activity throughout early development of dusky kob <em>Argyrosomus japonicus</em> (Sciaenidae)

    Metabolic activity throughout early development of dusky kob <em>Argyrosomus japonicus</em> (Sciaenidae)

    Item type: Journal Article • Journal: African Journal of Marine Science
    The physiology of fishes in the early stages of development remains poorly assessed despite the importance of identifying energy bottlenecks in organisms faced with changing environmental conditions. This study describes the metabolic activity of dusky kob Argyrosomus japonicus throughout its...
  4. 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...
