Our planet is changing at paces never observed before. Species extinction is happening at
faster rates than ever, greatly exceeding the five mass extinctions in the fossil record …

Tip** points in complex systems may imply risks of unwanted collapse, but also
opportunities for positive change. Our capacity to navigate such risks and opportunities can …

Predator–prey interactions in natural ecosystems generate complex food webs that have a
simple universal body-size architecture where predators are systematically larger than their …

Relating biodiversity to ecosystem functioning in natural communities has become a
paramount challenge as links between trophic complexity and multiple ecosystem functions …

Natural populations consist of phenotypically diverse individuals that exhibit variation in their
demographic parameters and intra-and inter-specific interactions. Recent experimental work …

Research on the relationship between the architecture of ecological networks and
community stability has mainly focused on one type of interaction at a time, making difficult …

The global biodiversity crisis concerns not only unprecedented loss of species within
communities, but also related consequences for ecosystem function. Community ecology …

Localized ecological systems are known to shift abruptly and irreversibly from one state to
another when they are forced across critical thresholds. Here we review evidence that the …

The main drivers of global environmental change (CO2 enrichment, nitrogen deposition,
climate, biotic invasions and land use) cause extinctions and alter species distributions, and …

Given the unprecedented rate of species extinctions facing the planet, understanding the
causes and consequences of species diversity in ecosystems is of paramount importance …
