Factors affecting millipede, centipede and scorpion diversity in a savanna environment.
(2000)Millipedes, centipedes and scorpions are an important component of the ground-dwelling invertebrate fauna, and may have value as bioindicators of ground-dwelling invertebrate diversity. However, some level of understanding ... -
Factors affecting savanna tree sapling recruitment.
(2013)Savannas are globally important ecosystems characterized by the coexistence of trees and grasses. Woody plants, which are slow-growing dominant life forms, influence the physiognomic structure and function of savanna ... -
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 ... -
Feeding ecology and carrying capacity of a reintroduced pack of African wild dogs in a relatively small, fenced reserve.
(2010)Reintroduction has been used successfully as a tool to restore declining populations of many threatened species. However, the lack of detailed evaluations of past reintroduction attempts has hindered a priori planning of ... -
The feeding ecology of nectarivorous birds in the Natal Drakensberg.
(1987)No abstract available. -
The feeding ecology of the African wild dog Lycaon pictus in Hluhluwe- Umfolozi Park.
(1996)The small population size of wild dog Lycaon pictus (10) in Hluhluwe-Umfolozi Park (HUP) and the decline in their numbers since 1992, has caused concern for their survival and consideration of further introductions. In ... -
Feral cats (Felis catus) in an urban conservancy : University of KwaZulu- Natal, Howard College campus.
(2005)The resident feral cat (Felis catus) population on the University of KwaZulu-Natal (UKZN), Howard College campus (HCC) in Durban, South Africa was studied from March 2004 to November 2005. This study was initiated as the ... -
Field ecology and impact of the seed-feeding beetle Acanthoscelides macrophthalmus, a biological control agent of the invasive tree Leucaena leucocephala, in the KwaZulu-Natal coastal region.
(2014)Introduced for agroforestry, the Mexican tree Leucaena leucocephala (Fabaceae) has become invasive in several tropical and subtropical regions worldwide. In South Africa, the most notable infestations are located in the ... -
Field evaluation and characterisation of the mode of imazapyr tolerance in three mutant sugarcane genotypes.
(2016)Abstract available in PDF file. -
The financial and economic feasibility of biodigester use and biogas production for rural households.
(2011)In South Africa, sustainable development is set in the context of two separate economies. The second of these economies consists of the rural population and is characterised by poverty and stagnant development. Sustainable ... -
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 ... -
Fleshy-fruited invasive plant species in KwaZulu-Natal, South Africa: native avian seed dispersal and impact assessment.
(2019)Globally, alien plant species have been recognised as a major threat to biodiversity. The increased global trade and travel have resulted in the increased introduction of new species. Direct or indirect introductions of ... -
Flexibility in metabolic rate in a small Afrotropical bird Zosterops virens.
(2014)The scientific literature contains hundreds of studies on avian basal metabolic rate (BMR), many of which assumed that BMR was fixed for each species. Yet those from the last few decades have shown avian BMR to be a flexible ... -
Fluctuating asymmetry in the redcollared widow : testing theories of sexual selection.
(1997)Sexual selection is usually invoked to explain the evolution of elaborate epigamic characters in animals. However, the mechanism by which female choice operates is poorly understood, and it is not clear whether female choice ... -
Foliar secretory cavities of Vepris lanceolata (Lam.) G. Don (Rutaceae): micromorphology and chemical composition of the secretion.
(2017)Secretory structures such as ducts, trichomes and cavities consist of cells that are primary sites synthesizing essential oils and other phytochemical compounds with medicinal properties. Little is known about the ... -
Food preferences and feeding interactions among browsers and the effect of an exotic invasive weed Chromolaena odorata on the endangered black rhino (Diceros bicornis), in an African savanna.
(2009)Biodiversity changes, often resulting from climate change, land transformation, and the transportation of organisms across geographical barriers are among the most important human induced global changes. To optimize the ... -
Forage systems for goat production in South Africa.
(2011)Goats are found in almost every country and are an important source of protein and produce lactose-free milk. In South Africa, survival rates of goat kids are low, mainly due to malnutrition. Intensive goat production ... -
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 ... -
Friendly neighbours? Investigating ecological facilitation between Thunbergia atriplicifolia (Acanthaceae) and Exochaenium grande (Gentianaceae).
(2018)Wildflowers that co-exist, share similar floral signals and flower simultaneously, may interact with the same pool of pollinators, therefore sharing pollinator species and individuals. Floral similarity could be a result ...
