Bird species richness and densities in relation to sulphur dioxide gradients and environmental variables
(Taylor & Francis, 2017)The expansion of coal-fired power stations in South Africa has resulted in growing environmental concerns as they are the largest emitters of sulphur dioxide (SO2). Sulphur dioxide emissions from power plants pose a potential ... -
Climate and food resources shape species richness and trophic interactions of cavity‐nesting Hymenoptera
(Wiley, 2020)Aim: Temperature, food resources and top-down regulation by antagonists are considered as major drivers of insect diversity, but their relative importance is poorly understood. Here, we used cavity-nesting communities of ... -
Diversity patterns of plants and arthropods in soybean agroecosystems in the grassland biome of South Africa
(Smujo, 2020)Soybean is widely cultivated in the grassland biome of South Africa (ca. 800 000 ha per annum). Yet the possible effects that large-scale cultivation of soybean has on biodiversity in adjacent habitat are not fully ... -
Tree diversity affects chlorophyll a fluorescence and other leaf traits of tree species in a boreal forest
(Oxford Univ Press, 2017)An assemblage of tree species with different crown properties creates heterogeneous environments at the canopy level. Changes of functional leaf traits are expected, especially those related to light interception and ...
