SUMMARY 1. Shallow lakes and ponds contribute disproportionally to species richness relative to other aquatic ecosystems. In-lake conditions (e.g. presence of submerged plants) seem to play a key role in determining ...

Worldwide, alien plant invasions have been intensively studied in the past decades, but mechanisms controlling the invasibility of native communities are not fully understood yet. The stochastic niche hypothesis predicts ...

Aim: Local effects of ecosystem engineers on biodiversity can scale up to the landscape level, stressing the importance of ecological processes as determinants of species richness at larger spatial scales. In harsh ...

Ecosystem engineers are organisms able to modulate environmental forces and, hence, may change the habitat conditions for other species. In so doing, ecosystem engineers may affect both species richness and evenness of ...

Abstract Background Latitudinal and altitudinal patterns of plant species richness have frequently been related to different climate variables such as precipitation, ...

In this work, we investigated the factors that determine the distribution of galling insects in high-altitude grasslands, locally called campos de altitude' of Mantiqueira Range and tested whether 1) richness of galling ...
