Metabolic physiology of Colubrid dietary specialists, Dasypeltis scabra and Dasypeltis inornata.
(2009)Metabolic rate (MR) and digestive duration are thermally dependant, and energy usage changes as body temperature (Tb) changes. Increased Tb during digestion causes a rapid increase in VO2 and a shorter postprandial metabolic ... -
Metabolic responses to hyperthermia in two small desert mammals, the Pygmy rock mouse, Petromyscus Collinus and the Namaqua rock mouse, Aethomys Namaquensis.
(2012)The negative consequence of recent climate change on the Earth’s biodiversity has become more evident in recent years. Some animals, due to insularity or habitat fragmentation, are unable to shift their ranges altitudinally ... -
Mitochondrial DNA variability between selected populations of Otomys irroratus (Muridae:Otomyinae)
(1993)An interpopulation study was done on the rodent species Otamys irroratus (Muridae:Otomyinae) using restriction fragment length Polymorphisms to examine the mitochondrial DNA (mtDNA) of 30 vlei rats (Otamys irroratus) from ... -
Modeling the spatial ecology of lions (Panthera leo) in Hluhluwe - Umfolozi park.
(2002)While many studies have been done on Lions, relatively little work has been conducted on how they interact with local habitats and the factors of importance in determining home ranges and territories. The interactions ... -
Monitoring the brown wattle mirid, Lygidolon Laevigatum (Hemiptera : Miridae)
(1995)No abstract available. -
Movements, nesting and the effects of pollution on the Nile crocodile (Crocodylus niloticus) in the Olifants River, Kruger National Park.
(1999)A pilot study was launched in 1993 to determine the movements of crocodiles in the Olifants River in Kruger National Park (KNP). This turned into a research project in 1994 and lasted for five years until 1998. The ... -
Patterns of distribution, diversity and endemism of terrestrial molluscs in South Africa.
(2007)Molluscs are an important component of South Africa’s biodiversity. The assessment of distribution patterns and factors influencing the biogeographic distribution are an integral part of assessing the conservation status ... -
Patterns of genetic variation in Mops leucostigma (Molossidae) from Madagascar and the Comoros.
(2008)The synanthropic molossid bat, Mops leucostigma (Allen 1918), is widely distributed across Madagascar and has recently been described from the Comoros. M. leucostigma individuals from eastern Malagasy populations are ... -
The pest status and chemical control of whitegrubs and cutworms in forestry in the Natal Midlands.
(1995)The limited availability of land to forestry and the ensuing emphasis on intensive silviculture, developed a renewed interest in soil pests in the establishment of plantations. Ten field trials were planted ... -
Physiological aspects of torpor in the fat mouse (Steatomys pratensis, Dendromurinae)
(1990)Several aspects of the physiology of the fat mouse Steatomys pratensis natalensis were studied in the laboratory using standard techniques and custom-made data-logging equipment. The fat was studied both from a morphological ... -
Population genetic studies of Fasciola species from cattle and selected wildlife species in Zimbabwe and localities of KwaZulu-Natal and Mpumalanga provinces of South Africa.
(2014)The objective of the study was to confirm the species and determine the genetic diversity of the confirmed Fasciola species from cattle and selected wildlife hosts from Zimbabwe and KwaZulu-Natal and Mpumalanga provinces ... -
A preliminary investigation into the status, distribution and some aspects of the foraging ecology of the southern ground hornbill (Bucorvus cafer) in Natal.
(1990)A study on the distribution, status and selected aspects of the foraging ecology of B. cafer in Natal, was undertaken from January 1989 to December 1990. A census was initiated to assess the distribution of B. cafer ... -
Range expansion of the Hadeda Ibis (Bostrychia hagedash) in Pietermaritzburg, KwaZulu-Natal : an urban environment.
(2014)Many animal species are typically negatively affected by urbanization; however those species which are not negatively affected are those that can use resources available in urban areas to survive. Hadeda Ibis (Bostrychia ... -
Restriction patterns of mitochondrial DNA in natural populations of the murid species Otomys irroratus.
(1994)Mitochondrial DNA (mtDNA) was isolated from 8 different natural populations of the rodent species Otomys irroratus (Muridae: Otomyinae) and from one population of the species 0. angoniensis occurring in South Africa. MtDNA ... -
Revision of some dwarf chameleons (Sauria: Chamaeleonidae: Bradypodion) from eastern South Africa.
(2001)This dissertation has the object of re-examining the taxonomic status of the dwarf chameleons related to Bradypodion melanocephalum and Bradypodion caffrum from eastern South Africa. The historical context of previous ... -
The rock lobsters (Palinuridae) of South-East Africa, with particular reference to the life histories of Panulirus Homarus and Palinurus Delagdae.
(1970)Abstract available in PDF file. -
Rodent damage control in commercial forestry in the Natal Midlands, South Africa.
(1996)Rodents cause damage in commercial forests by gnawing at the bark of the trees. It is currently estimated that rodent damage in commercial forestry costs the industry R50 million per annum. The species of rodents which ... -
The role of Anopheles arabiensis (Diptera: Culicidae) in malaria transmission and control in Gokwe and Binga districts, Zimbabwe..
(1996)Opportunistic feeding behaviour and partial exophily make An. arabiensis much more difficult to control by indoor residual spraying than any other vector in the Afro-tropical region. The persistent malaria outbreaks in ... -
Scrounging herbivores use both patch quality and dominance status of patch holders when deciding which patch to join.
(2011)One of the major costs of group living is increased competition due to social information. Social information allows foragers to gain information about the location and the quality of food patches from observing other group ... -
Seasonal home range and foraging movements of the Wahlberg's epauletted fruit bat (Epomophorus wahlbergi) in an urban environment.
(2012)Urbanisation through the process of habitat loss and fragmentation has caused drastic changes in ecosystem dynamics around the world. Many species can no longer survive in these urban areas; however there are those species ...
