-
(South African Society for Animal Science, 1999)Animals, maintained from birth on a higher and lower fibre diet, were slaughtered when postnatal growth curves flattened off. Males tended to be larger than females. The meat of females tended to have higher lipid (9.2 ...
-
(Elsevier, 2005-06)In this paper, we investigate the formation and function of the multilevelled, fission–fusion social structure in a free-ranging African elephant, Loxodonta africana, population. We quantitatively identified the existence ...
-
(Elsevier, 2006)The Damaraland mole-rat is a eusocial, subterranean rodent that exhibits a seasonal breeding. Non-reproductive females show physiological suppression of reproduction whilst in the confines of the natal colony. This study ...
-
(Faculty of Theology, University of Pretoria, 2006)Many evolutionary biologists argue that human sexual behaviour can be studied in exactly the same way as that of other species. Many sociologists argue that social influences effectively obscure, and are more important ...
-
(Elsevier, 2006-06)Aloe greatheadii var. davyana is the most important indigenous South African bee plant. Fresh, bee-collected and stored pollen of this aloe was collected and analysed for its nutritional content, including amino acid and ...
-
(Elsevier, 2006-09)The Lesotho mole-rat is a social subterranean rodent that occurs at altitude in the Drakensberg mountain range. As a consequence of living permanently underground these animals rarely if ever are exposed to light. The ...
-
(Blackwell, 2006-10)In comparison with other tropical forest land uses such as selective logging, little is known of the impacts on wildlife of the many forms of small-scale agriculture practised across the tropics. We present density estimates, ...
-
(Blackwell, 2006-10)Aims The fauna of mountains and their surrounding regions are likely to be influenced principally by two biological processes: horizontal colonization along similar altitudinal levels by elements originating from lineages ...
-
(Faculty of Theology, University of Pretoria, 2007)The debate between evolution and intelligent design is usually presented by evolutionary biologists as a clash between science and non-science (creationism and religion) and therefore as a sterile argument which science ...
-
(Springer, 2007)In southern Africa, Aloe marlothii flowers during the dry winter season and offers copious dilute nectar to a variety of birds. Avian abundance and community composition were monitored at an A. marlothii forest at Suikerbosrand ...
-
(NISC, 2007)We investigated the influence of forest fragment size and isolation on the bird assemblages in the species- and endemic-rich sand forests of the Maputaland Centre of Endemism, southern Mozambique. Point-centre surveys ...
-
(Southern African Wildlife Management Association, 2007)The banana bat, Neoromicia nanus, is characterized by seasonal monoestrous breeding. This study examined the reproductive timing and strategies used by N.nanus in the Province of Mpumalanga, South Africa. Male and female ...
-
(Southern African Wildlife Management Association, 2007)Modelling fur seal populations requires the accurate assessment of demographic parameters such as age-specific mortality. Owing to the highly variable mortality rates that pups are subject to, mortality of this age class ...
-
(Blackwell, 2007)Elephants confined to protected areas could affect co-occurring species. We expected measurable deviations in the density, species number, turnover and composition, abundance-incidence and rank-abundance patterns of woody ...
-
(Academy of Science of South Africa, 2007-01)Fusarium circinatum is the causal agent of a serious disease of seedlings in South African pine nurseries. Insects, especially fungus gnats (Diptera: Sciaridae, Mycetophlidae), are suspected of transmitting this fungus in ...
-
(Elsevier, 2007-01)Elephants occur in landscapes where temperatures can reach 50 °C. Due to their large size they may face physiological problems of dissipating heat during such high temperatures. In spite of this, no one seems to have ...
-
(Elsevier, 2007-01)We examined pollination biology of Acacia nigrescens Oliver, flowering at the end of the dry season in Kruger National Park, South Africa. A. nigrescens produces small quantities of concentrated nectar, and has abundant ...
-
(Elsevier, 2007-01)Conservation management options for southern African elephants range from local to regional scales. Here we review these options and argue in favour of actions that will deal with the causes rather than symptoms of elephant ...
-
(Springer, 2007-01)The first recorded outbreak of avian influenza (AI) in South African chickens (low pathogenicity H6N2) occurred at Camperdown, KwaZulu/Natal Province (KZN) in June 2002. To determine the source of the outbreak, we defined ...
-
(Public Library of Science, 2007-02-14)Parametric kernel methods currently dominate the literature regarding the construction of animal home ranges (HRs) and utilization distributions (UDs). These methods frequently fail to capture the kinds of hard boundaries ...
