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 ... -
The behavioural thermoregulation and ecophysiology of the leopard tortoise (Geochelone pardalis) in the Nama-Karoo.
(2007)The leopard tortoise (Geochelone pardalis) is the largest of the southern African tortoise species and has a wide distribution range. However, there is a lack of ecological and physiological information about the species, ... -
Beyond DNA sequencing : integrative approaches to resolving selected higher and lower taxonomic problems in Afrotropical Chiroptera.
(2013)Of the approximate 300 currently recognised bat species known from the Afrotropics, very few have been studied in sufficient detail to a) provide accurate species and distributional limits for extant taxa, b) identify ... -
Biological studies of bottlenose dolphins from Natal coastal waters.
(1989)The biology of bottlenose dolphins from the east coast of southern Africa is investigated. Births occur predominantly in summer, after a one year gestation period. Calves are born at a length of approximately 103 cm and ... -
The biology and systematic relationships of Crowned, Blackwinged and Lesser Blackwinged Plovers.
(1987)Plovers was compared with particular reference to breeding biology, feeding ecology and habitat preference. Crowned and Blackwinged Plovers coexisted in mixed flocks in grasslands which aided predator detect ion and ... -
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 ... -
Black rhinoceros (Diceros bicornis) habitat selection and movement analysis.
(2010)Many aspects of habitat selection have been largely ignored in conservation planning of large mammals, including variation between day and night movement patterns, inter-individual niche variation of conspecifics and ... -
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 ... -
Comparative feeding and foraging behaviour of the biocontrol agents Chilocorus spp. (Coccinellidae)
(1991)This study focuses on the effective biocontrol agent Chilocorus nigritus (Fabricius). Its behaviour and ecology were compared with other Chilocorus spp. where appropriate, to elucidate why this species is such an effective ... -
Comparative studies on related free-living and pathogenic limax amoebae with particular reference to Naegleria.
(1977)Over two hundred and forty strains of limax amoeba including eight potentially pathogenic strains of Naegleria and Acanthamoeba were isolated from a variety of habitats in South Africa. The amoeboid and flagellate stages ... -
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, ... -
The conservation ecology of the Nile crocodile (Crocodylus niloticus) at Ndumo Game Reserve in North Eastern KwaZulu-Natal and the Rio Maputo floodplain in South Eastern Mozambique.
(2013)Up until 1969 Nile Crocodiles (Crocodylus niloticus) were considered as vermin in South Africa and were actively persecuted throughout the country. In an effort to re-establish viable populations within protected areas in ... -
Distribution patterns of epigaeic invertebrates across Afromontane forest/grassland ecotones, in KwaZulu-Natal, South Africa.
(2000)Considered key landscape elements, ecotones play an important role in landscape ecology. In heavily fragmented, or heterogeneous landscapes, ecotones become a major, even dominant, feature. Yet, there are relatively few ... -
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 ... -
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 ... -
Ecological studies of bottlenose and humpback dolphins in Maputo Bay, southern Mozambique.
(2008)The ecology and population biology of bottlenose and humpback dolphins inhabiting the Maputo Bay, Southern Mozambique were studied through boat based photoidentification surveys and behavioural methods between December ... -
Ecology and conservation of the Cape vulture in the Eastern Cape Province, South Africa.
(2016)Abstract available in PDF file. -
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 ... -
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 ...
