The effect of biodiversity on productivity changes over time in duckweed communities

open access: yesOikos, EarlyView.
Several studies have shown that increased biodiversity can lead to increased productivity in plant communities. This relationship can be explained by a selection effect caused by the dominance of one or a few species that drive productivity, and by a complementarity effect resulting from the use of resources by the different species.

Prey and prejudice: predation by the European bee‐eater Merops apiaster has species‐specific effects on the ecology and genetics of bumblebees

open access: yesOikos, EarlyView.
Predation is a major ecological force, but its effect on bees has rarely been studied. Here, we investigated whether the presence of the European bee‐eater Merops apiaster, a migratory bird species and major bee predator, decreases the abundance and body size of three common bumblebee species (Bombus lapidarius, B. terrestris and B.

Non‐native species affect the long‐term dynamics of native stream fish assemblages

open access: yesOikos, EarlyView.
Characterizing the temporal changes of biotic communities and disentangling the importance of their driving mechanisms are central themes in ecology and environmental management. Non‐native species have multiple adverse impacts on native communities and species.
