Darwin used the metaphor of a 'tangled bank'to describe the complex interactions between
species. Those interactions are varied: they can be antagonistic ones involving predation …

Summary 1 A fundamental goal of ecological network research is to understand how the
complexity observed in nature can persist and how this affects ecosystem functioning. This is …

A census of the biomass on Earth is key for understanding the structure and dynamics of the
biosphere. However, a global, quantitative view of how the biomass of different taxa …

A number of studies indicate that tropical arthropods should be particularly vulnerable to
climate warming. If these predictions are realized, climate warming may have a more …

Spiders have been suspected to be one of the most important groups of natural enemies of
insects worldwide. To document the impact of the global spider community as insect …

Most eukaryotic organisms are arthropods. Yet, their diversity in rich terrestrial ecosystems is
still unknown. Here we produce tangible estimates of the total species richness of …

Most studies of plant–animal mutualisms involve a small number of species. There is almost
no information on the structural organization of species-rich mutualistic networks despite its …

Food‐web structure mediates dramatic effects of biodiversity loss including secondary
andcascading'extinctions. We studied these effects by simulating primary species loss in 16 …

Networks from a wide range of physical, biological, and social systems have been recently
described as “small-world” and “scale-free.” However, studies disagree whether ecological …

Small invertebrates are function-ally important in many terrestrial and aquatic ecosystems
(Wilson 1992, Freckman et al. 1997, Palmer et al. 1997, Postel and Carpenter 1997). In …
