(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 ...
-
(South African Veterinary Association, 2007-06)The incidence of tusklessness varies between free-ranging African elephant populations. Sex-linked genetic drift predicts 2 outcomes - the condition becomes fixed and sex-specific incidences diverge when populations are ...
-
(Blackwell, 2008)Many studies have investigated why males and females segregate spatially in sexually dimorphic species. These studies have focused primarily on temperate zone ungulates in areas lacking intact predator communities, and few ...
-
(Ecological Society of America, 2008)Shifting prey selection has been identified as a mechanism potentially regulating predator–prey interactions, but it may also lead to different outcomes, especially in more complex systems with multiple prey species ...
-
(Blackwell, 2008)Boat-based surveys were conducted from August 2002 to July 2003 to study the activity patterns, spatial pattern of area use, and group characteristics of Sotalia guianensis in Sepetiba Bay, southeast Brazil. Predetermined ...
-
(Springer, 2008)In South Africa, a plan was launched to manage separate sub-populations of endangered African wild dogs (Lycaon pictus) in several small, geographically isolated, conservation areas as a single meta-population. This intensive ...
-
(Blackwell, 2008)Circadian rhythms of locomotor activity have been investigated in several African mole-rat species. Even though mole-rats spend most of their lives in underground burrows devoid of light, studies have shown that they do ...
-
(Blackwell, 2008)Identifying traits that affect the reproductive success of individuals is fundamental for our understanding of evolutionary processes. In cooperative breeders, a dominant male typically restricts mating access to the ...
-
(Blackwell, 2008)The spread of game ranching in southern Africa provides opportunities for the reestablishment of populations of endangered wild dogs extirpated by livestock ranchers. However, this potential has not been realized, partly ...
-
(Blackwell, 2008)Size relationships are central in structuring trophic linkages within food webs, leading to suggestions that the dietary niche of smaller carnivores is nested within that of larger species. However, past analyses have not ...

(Blackwell, 2008)No abstract available
-
(Blackwell, 2008)Knowledge of a species' ranging behaviour is both fundamental to understanding its behavioural ecology and a prerequisite to planning its management. Few data exist on the spatial ecology of cheetahs Acinonyx jubatus outside ...
-
(Blackwell, 2008)In cooperative societies with high reproductive skew, selection on females is likely to operate principally through variation in the probability of acquiring dominant status and variation in reproductive success while ...
-
(South African Veterinary Association, 2008-03)Captive and wild African elephants frequently suffer tusk fractures. Several institutions shorten the tusks of captive elephants to reduce fractures and injury as a result of behaviour within enclosures. Fracturing or ...
-
(Elsevier, 2008-07)In many bird species with biparental care for young in the nest, hungry chicks beg repeatedly and parents adjust their feeding rate to the call rate of young. Repetitive calling also occurs in fledglings and in some mammals ...
-
(Elsevier, 2008-08)Warthogs, Phacochoerus africanus, are an unusual ungulate. They are facultative cooperative breeders where females within the same population display both solitary and cooperative reproductive strategies. Warthogs require ...
-
(Southern African Wildlife Management Association, 2008-10)Like many pinniped species, southern elephant seals (Mirounga leonina) are conducive to long-term population studies using mark-recapture techniques. The twenty-four year longitudinal dataset at sub-Antarctic Marion Island ...
-
(Southern African Wildlife Management Association, 2008-10)In gregarious species, rates of foraging behaviour are often positively related to group size while there is simultaneously a negative relation between group size and vigilance. Although the mechanisms underlying these ...
-
(Blackwell, 2009)Heaviside's dolphins, Cephalorhynchus heavisidii, are endemic to southwestern Africa, where they are exposed to unknown levels of anthropogenic threats, including inshore set netting. Using photo-ID data collected over 3 ...
-
(Current Zoology, 2009-01)Knowledge of carnivore diets is essential to understand how carnivore populations respond demographically to variations in prey abundance. Analysis of stable is a useful complement to traditional methods of analyzing ...
