Open AccessWater availability, bedrock, disturbance by herbivores, and climate determine plant diversity in South-African savanna
To identify factors that drive plant species richness in South-African savanna and explore their relative importance, we sampled plant communities across habitats differing in water availability, disturbance, ...

Open AccessThe invasive cactus Opuntia stricta creates fertility islands in African savannas and benefits from those created by native trees
The patchy distribution of trees typical of savannas often results in a discontinuous distribution of water, nutrient resources, and microbial communities in soil, commonly referred to as “islands of fertility...

Open AccessMetabolomic differences between invasive alien plants from native and invaded habitats
Globalization facilitated the spread of invasive alien species (IAS), undermining the stability of the world’s ecosystems. We investigated the metabolomic profiles of three IAS species: Chromolaena odorata (Aster...

Open AccessInvasion syndromes: a systematic approach for predicting biological invasions and facilitating effective management
Our ability to predict invasions has been hindered by the seemingly idiosyncratic context-dependency of individual invasions. However, we argue that robust and useful generalisations in invasion science can be...
