Aspects of the ecology of spotted hyena (Crocuta crocuta) in relation to prey availability, land use changes and conflict with humans in western Zimbabwe.
(2018)Patch selection by carnivores is affected by various factors including availability of prey and denning areas, extent of vegetation cover, competition from sympatric large carnivores and anthropogenic habitat change among ... -
Aspects of the molecular systematics, taxonomy and population genetics of Otomops (Chiroptera: Molossidae) in Africa and Madagascar.
(2015)Abstract available in the print copy. -
Assessment of roadkills in Hluhluwe-Imfolozi Park, KwaZulu-Natal, South Africa.
(2017)Anthropogenic land-use activities are considered to be the main contributor to current worldwide changes in natural ecosystems. South Africa is one of the countries that has been severely affected by changing land-use. The ... -
Behavioural responses of rodents to the scent and taste of compounds associated with sugar and protein degradation : implications for the evolution of chemical signals in rodent-pollinated flowers.
(2015)Volatile compounds in nectar may influence the behavioural responses of animal flower visitors, and thus have fitness consequences for both animal and plant mutualists. Rodents may use certain volatiles associated with ... -
The challenges and opportunities in conserving wide-ranging cross-border species : a case study of the Greater Mapungubwe Transfrontier Conservation Area elephant population.
(2015)Transfrontier conservation areas potentially play a key role in conserving biodiversity and promoting socioeconomic development. However, socio-political factors often affect their effectiveness in achieving biodiversity ... -
Chemokines and haematological profile in Sprague-Dawley rats infected with trichinella Zimbabwensis and Plasmodium berghei ANKA.
(2017)Trichinellosis is an important re-emerging parasitic zoonosis caused by nematode species of the genus Trichinella and Plasmodium falciparum malaria is among the leading causes of mortality and morbidity in sub-Saharan ... -
Comparative studies of the ultrastructure of Entamoeba histolytica and Entamoeba coli.
No abstract available. -
Cytokine and haemtological profiles in sprague-dawley rats experimentally infected with trichnella zimbabwensis and plasmodium berghei Anka.
(2017)Abstract available in PDF file. -
Development and utilization of a river system model to integrate human and ecological water requirements in a southeastern United States river basin.
(2016)Abstract available in PDF file. -
Diet preference of common mynas (Sturnus tristis) in urban areas of Pietermaritzburg and Durban, KwaZulu-Natal.
(2017)Urbanization is one of the anthropogenic land use changes with a negative impact on biodiversity generally. However, some species are persisting well in urban areas and are termed urban exploiters. One of these species is ... -
DNA barcoding of KwaZulu-Natal afromontane forest parmelia (parmeliaceae) species: a molecular approach to accurate specimen identification and sensitivity to climate change.
(2018)Accurate species identification is challenging, especially in groups with subtle taxonomically diagnostic characters such as lichens. Molecular-based techniques have shown to be a valuable tool for accurate specimen ... -
The effect of wastewater treatment works on foraging ecology, haematology, detoxification organs and reproduction in an urban adapter, the banana bat (Neoromicia nana).
(2015)Natural land is rapidly becoming urbanized. Wastewater Treatment Works (WWTWs) are a ubiquitous component of this urban landscape. WWTWs may provide profitable foraging areas for insectivorous bats because of their ... -
The effects of petroleum hydrocarbon contamination on selected intertidal macrophytes and meiofauna.
(2015)The effects of bunker fuel oil on the growth of A. marina, B. gymnorrhiza and R. mucronata were investigated in glasshouse and field experiments. The effects of oil on community structure in micro-organisms were also ... -
The effects of sexual dimorphism on the movements and foraging ecology of the African elephant
Abstract available on PDF file. -
Efficacy of maslinic acid and chloroquine on the co-infection of Plasmodium berghei and Trichinella zimbabwensis in Sprague-Dawley rats.
(2015)Many people living in Africa and elsewhere in the tropics suffer from combined malaria, soil-transmitted infections and tissue-dwelling nematodes. Most of these deaths are prevalent in sub-Saharan Africa (SSA) where the ... -
The emission of volatile organic compounds (VOCs) from rotting fruits and wilting flowers.
(2015)Plants and the microbes that feed on them produce a high diversity of volatile organic compounds (VOCs) that often mediate interspecies communication with other organisms. Two main functions of VOCs emitted by plants are ... -
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 ...
