The ecology and conservation of blue duiker and red duiker in Natal.
(1990)The ecology of blue duikers Philantomba monticola and red duikers Cephalophus natalensis was studied in three lowland coastal evergreen forests in Natal. Variation in population densities, estimated with numerous census ... -
The socioecology and conservation of the Samango monkey (Cercopithecus mitis erythrarchus) in Natal.
(1990)The samango monkey (Cercopithecus mitis erythrarchus) is the southern most representative of the polytypic mitis group. The samango is also the only truly arboreal guenon to have radiated as far as 30°S. At southern ... -
The ecology, over-wintering and population dynamics of the pre-imaginal stages of the Anopheles gambiae Giles complex (Diptera : culicidae) in northern Natal, South Africa.
(1991)This study investigated aspects of the breeding biology, ecophysiology, morphology, over-wintering and population dynamics of the pre-imaginal stages of members of the Anopheles gambiae complex in northern Natal, South ... -
The dynamics of social relationships among female Chacma baboons (Papio cynocephalus ursinus) in Zululand.
(1993)The focus of this study is the effect of environmental conditions on the social relationships among females in a free-ranging troop of chacma baboons (Papio cynocephalus ursinus), in a southern woodland habitat. The ... -
The evolution and socio-ecology of two populations of the Vlei Rat, Otomys irroratus.
(1993)This work investigated two important evolutionary processes - speciation and adaptive variation - in two chromosomally-distinct allopatric Natal Midlands populations of the vlei rat Otomys irroratus. The two populations, ... -
The biology, ecology and conservation of four Flufftail species, Sarothrura (Aves: Rallidae)
(1994)The distribution, status, biology and ecology of four flufftail species were investigated in South Africa and Zimbabwe. The Redchested Flufftail is a successful and widely distributed species, occupying a wide range of ... -
The analysis of erythropoiesis and other early developmental events in the chick embryo using mesodermal-inducing factors.
(1994)The causal and temporal aspects of blood tissue specification in the chick embryo were investigated in this study. The main focus was on the role of basic fibroblast growth factor (bFGF) in the determination of 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 ... -
Plant molluscicides for snail control in the South African context.
(1994)Despite more than half a century of international research on schistosomiasis control, this disease remains a public health concern in many Third World countries. Four to five percent of the world's population is estimated ... -
The Anostraca (crustacea : Branchiopoda) of southern Africa.
(1994)The Anostraca are a group of crustaceans belonging to the class Branchiopoda. They are predominantly restricted to temporary, inland waterbodies, which in southern Africa, include rockpools, animal wallows, and large ... -
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 ... -
Chromosomal evolution in the Vlei Rat Otomys irroratus.
(1996)Proponents of the recognition concept of species hold that isolating mechanisms, including chromosome rearrangements, play no role in speciation while the more commonly accepted biological species concept proposes that ... -
Effects of temperature on members of the Anopheles gambiae complex (Diptera: Culicidae) in South Africa : implications for malaria transmission and control.
(1996)This study investigated the effects of temperature and relative humidity (both controlled and natural) on the lifecyle and morphology of adults of members of the Anopheles gambiae complex in northern KwaZulu-Natal, South ... -
A comparative study of communication in six taxa of southern African elephant-shrews (macroscelididae)
(1996)Aspects of olfactory, auditory, visual and tactile communication were investigated in five Elephantulus species (E. brachyrhynchus, E. edwardii, E. intuft, E. myurus, E. rupestris) and Macroscelides proboscideus, ... -
Behaviour and social organization of the African Jacana Actophilornis africanus.
(1997)The behaviour, nesting, food resources and mating system of the African Jacana Actophilornis africanus were studied at Muzi Swamp, northern KwaZulu-Natal and at Darvill Sewerage Works, KwaZulu-Natal. African Jacanas ... -
Population genetics of the striped-mouse, Rhabdomys Pumilio (Sparrman, 1784)
(1999)The striped-mouse, Rhabdomys pumilio, is widely distributed throughout southern Africa within a variety of habitats and rainfall regimes. It is found at sea level in the Eastern and Western Cape regions and at altitudes ... -
Patterns, mechanisms and evolution of avian facultative hypothermic responses : a southern African perspective.
(2001)Recent evidence suggests that avian facultative hypothermic responses are more common than previously thought. Traditionally, several categories of avian hypothermic responses have been recognized, and are frequently ... -
The ecology and conservation biology of the Black-cheeked Lovebird Agapornis nigrigenis in Zambia.
(2003)This study was undertaken to investigate the ecology of the Black-cheeked Lovebird Agapornis nigrigenis in the wild. Prior to this study little was known about the ecology of this parrot or other members of the genus ... -
Effect of soil factors on parasitic nematodes of sugarcane in KwaZulu- Natal, South Africa.
(2004)Nematicides are not only expensive and unaffordable to small-scale farmers but are also harmful to the environment as they kill both the target organisms and non-target micro and macro-organisms, thereby destabilising the ... -
Dragonfly assemblage dynamics and conservation at small reservoirs in KwaZulu-Natal, South Africa.
(2004)A study of the odonate fauna was carried out at the edge of a major escarpment, in eastern South Africa, using the same methodology as has been used in the temperate regions to obtain a sub-tropical perspective. The study ...
