(2010)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 South ...
-
(Blackwell, 2009)Elephant impacts on spider assemblages, and the potential use of spiders as indicators of habitat changes, was assessed in central Maputaland, South Africa. Three habitats, namely undisturbed sand forest, elephant disturbed ...
-
(Springer, 2009)The spatial distribution of alien species richness often correlates positively with native species richness, and reflects the role of human density and activity, and primary productivity and habitat heterogeneity, in ...
-
(Blackwell Publishing LtD, 2009)Aim To examine whether at a sub-continental scale range-limited species tend to occur close to areas of transition between vegetation boundaries more often than expected by chance. Location South Africa and Lesotho. Methods We ...
-
(Blackwell Publishing LtD, 2008)While small antelopes are becoming increasingly threatened, knowledge of their biology is often limited. Management recommendations are therefore frequently based on insufficient information. One declining small antelope ...
-
(Blackwell, 2008)Aim To investigate explanations for the maintenance of a positive spatial species richness – human population density correlation at broad scales, despite the negative impact of humans on species. These are (hypotheses 1 ...
-
(Blackwell, 2008)Aim To determine how well variation in median body size of avian assemblages is predicted by (1) the environmental models usually employed in analyses of Bergmann’s rule and (2) random sampling from the regional body size ...
-
(Opulus Press Uppsala, 2008-05-07)Question: Do anthropogenic activities facilitate the distribution of exotic plants along steep altitudinal gradients? Location: Sani Pass road, Grassland biome, South Africa Methods: On both sides of this road, presence ...
-
(Academy of Science of South Africa, 2007-11)The common myna is an Asian starling that has become established in many parts of the world outside of its native range due to accidental or deliberate introductions by humans. The South African population of this species ...
-
(2005)This study explores the correlates of alien plant species richness in South Africa at the scale of quarter-degree squares (QDS; ≈ 25 x 27 km; 675km2). We considered all alien plant species for which we had records and a ...
-
(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 ...
-
(2006)A local community adjacent to Tembe Elephant Park, which is the largest protected portion of sand forest in South Africa, recently nominated a portion of their land for a community-based natural resource management project ...
-
(BLACKWELL PUBLISHING, 2006-11)As an alternative to kin selection, group augmentation theory provides a framework for evolutionary mechanisms maintaining cooperative breeding when individual fitness is positively related to group size. It is expected ...
-
(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)). ...
