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 ... -
Socio-economic and environmental deteminants of malaria in four malaria endemic provinces of Zambia.
(2015)A large fraction of the global malaria burden occurs in sub-Saharan Africa and its endemicity depends on the interaction of environmental factors, vectors, parasites and the host. In Zambia, the negative effect of the break ... -

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 ... -
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 ... -
Spatio-temporal analysis of woody vegetation data at various height classes within a semi-arid savanna : insights on environmental drivers, distributions and dynamics.
(2015)Savanna vegetation is regulated by bottom-up (e.g. soil and rainfall) and top-down (e.g. fire and herbivory) factors. Little is known about how these factors influence biodiversity at regional scales, particularly spatial ... -
