An experimental investigation of the effects of supplementary food and ground cover on small mammal population dynamics and community structure in a Swaziland grassland.
(1997)The primary aim of this study was to investigate the role of food supply and ground cover on the community structure, population dynamics and demography of terrestrial small mammals in a subtropical grassland. This aim ... -
Fast life in the slow lane : life history and energetics of a basal placental mammal Setifer setosus (Schreber, 1778).
(2014)There is increasing evidence that homeothermy (the maintenance of a high and stable body temperature-Tb) as observed in modern mammals was derived from an ancestral heterothermic (flexible Tb regulation) state. One of main ... -
Fleshy-fruited invasive alien plants and frugivores in South Africa.
(2011)South Africa is one of the world's most biologically invaded countries and has spent billions of rands on efforts to eradicate alien invasive plants. Chemical and mechanical control methods have varied in success and the ... -
Foraging and feeding behaviour of chacma baboons in a woodland habitat.
(1994)Savannah baboons (Papio cynocephalus) have been studied in numerous sites throughout Africa. They have been found to display a wide variety of foraging and feeding behaviours. The aim of this study was to describe and ... -
The freshwater Diaptomidae (Calanoida : Copepoda) of Southern Africa.
(1990)Freshwater copepod taxonomy has been neglected in southern Africa for more than 50 years and this has placed a constraint on research on the biology and ecology of this important component of the freshwater ... -
Genetic diversity of the Chaerephon leucogaster/pumilus complex from mainland Africa and the western Indian Ocean islands.
(2013)Chaerephon (Dobson, 1874), an Old World genus belonging to the family Molossidae, is part of the suborder Vespertilioniformes. Members of this genus are distributed across mainland Africa (sample sites; Tanzania, Yemen, ... -
Grasshopper ecology and conservation in the Nama-Karoo.
(2001)This study was undertaken in the Karoo, a semi-arid grazing land in South Africa, to elucidate the interaction between grasshopper assemblages and various aspects of the Karoo landscape. It falls into four sections, the ... -
Growth and reproduction in the fruit bat Epomophorus wahlbergi.
(1983)This study was carried out on the Natal South Coast between 30° 12' S and 30° 19' S, where 1085 Epomophorous wahlbergii were caught by mist-netting, and a captive breeding colony was kept between June 1977 and February ... -
A herpetological survey of the Transvaal.
(1989)This report discusses the taxonomy, distribution and ecology of the herpetofauna of the Transvaal based on a survey conducted over the past 10 years. Seventeen new forms, apart from four new taxa described during the ... -
The Holothurian fauna of Southern Africa.
(1984)The last thorough revision of the southern African holothurian fauna appeared in 1948 and since then there have been numerous additions to the fauna . A comprehensive revision of the fauna is here undertaken on the basis ... -
Host-parasitoid interactions of Eldana Saccharina (Lepidoptera: Pyralidae) in Cyperus Papyrus.
(1994)Since becoming a pest in graminaceous crops in Africa, the African sugarcane stalkborer Eldana saccharina Walker has been the subject of much study. Its very cryptic habits have precluded more commonly available control ... -
The incidence of helminths in pigs, sheep, cattle, impala and blesbok in the Transvaal.
(1980)The seasonal fluctuations in the worm burdens of pigs, sheep, cattle, impala and blesbok exposed to infestation on improved or natural pastures in the Transvaal were determined. The prevalence of infestation in pigs ... -
The influence of abiotic processes, competition and predation on the community structure of rodents and shrews.
(2012)Predation and abiotic processes rather than competition should influence the community structure of rodents and shrews with life histories characterised by high fecundity, short longevity and unstable populations. I ... -
The influence of turbidity on fish distribution in Natal estuaries.
(1984)Studies In other parts of the world have proved that turbidity affects aquatic life and work In Australia and North America has shown that the distribution of some fish species may be determined by the level of turbidity ... -
Infraspecific systematics of the yellow mongoose Cynictis penicillata.
(1990)Geographic variation was analysed in morphological (colour, morphometric) and genetic (electrophoretic, chromosomal) characters in the yellow mongoose cynictis penicillata, a diurnal, colonial, burrow-dwelling viverrid, ... -
An integrated approach to the management of common reedbuck on farmland in Natal.
(1983)This study was motivated by the Natal Parks Board which has been receiving a growing number of complaints from farmers concerning reedbuck grazing of commercial crops. The reedbuck is an important conservation species, ... -
Integrated physiology and behaviour of Thallomys nigricauda along an aridity gradient.
(2008)Climate change predictions suggest that the continent most vulnerable to climate change is Africa. The impacts of potential changes which include increases in air temperatures and rainfall variability are negative with ... -
Intrinsic and extrinsic influences on African large herbivore assemblages and implications for their conservation.
(2014)Understanding the intrinsic and extrinsic influences that affect large herbivore assemblages are important for protected area managers, especially if their current rate of population decline in Africa continues. I aimed ... -
The invasive potential of the freshwater snail Radix rubiginosa recently introduced into South Africa.
(2011)Invasions of ecosystems by exotic species are increasing and they may often act as a significant driver of the homogenization of the Earth’s biota, resulting in global biodiversity loss. Moreover, the addition of exotic ...
