The relative importance of environment, human activity and space in explaining species richness of South African bird orders
(Blackwell Publishing Ltd, 2008)
Aim To assess the relative importance of environmental (climate, habitat heterogeneity and topography), human (population density, economic prosperity and land transformation) and spatial (autocorrelation) influences, and ...
Micro-scale heterogeneity of spiders (Arachnida: Araneae) in the Soutpansberg, South Africa: a comparative survey and inventory in representative habitats
Coarse-scale studies that focus on species distributions and richness neglects heterogeneity that may be present at finer scales. Studies of arthropod assemblage structure at fine (1 x 1 km) scales are rare, but important, ...
People, species richness and human population growth
(BLACKWELL PUBLISHING, 2006-11-01)
Aim To investigate how the magnitude of conservation conflicts arising from positive relationships between human population size and species richness is altered during a period of marked human population growth (2% year(-1)). ...
The ecological effectiveness of protected areas: a case study for South African birds
(The Zoological Society of London, 2011)
While the importance of individual protected areas (PAs) to biological conservation is widely acknowledged, rather few empirical studies have explicitly attempted to assess their ecological effectiveness. Significantly, ...
Assessing the relative efficiency of termite sampling methods along a rainfall gradient in African savannas
(The Association for Tropical Biology and Conservation, 2013)
Although termites are ecosystem engineers in tropical and sub-tropical environments, the study of termite ecology is often constrained by sampling difficulties and a lack of established sampling protocols, particularly for ...
Predicting invasive alien plant distributions: how geographical bias in occurrence records influences model performance
Aim: To investigate the impact of geographical bias on the performance of ecological niche models for invasive plant species. Location: South Africa and Australia. Methods: We selected 10 Australian plants invasive in ...
