Nutrient availability and herbivory control the biomass of primary producer communities to
varying degrees across ecosystems. Ecological theory, individual experiments in many …

Why do species live where they live? What determines the abundance and diversity of
species in a given area? What role do species play in the functioning of entire ecosystems …

In theory, enrichment of resource in a predator-prey model leads to destabilization of the
system, thereby collapsing the trophic interaction, a phenomenon referred to as “the paradox …

Experiments assessing the effects of biodiversity on ecosystem functioning initially aimed at
establishing whether such relationships exist (eg Naeem et al. 1995; Tilman et al. 1996; …

Recent experiments, mainly in terrestrial environments, have provided evidence of the
functional importance of biodiversity to ecosystem processes and properties. Compared to …

From humans to hermit crabs to deep water plankton, all living things compete for locally
limiting resources. This universal truth unites three bodies of thought--economics, evolution …

The food web efficiency in two contrasting food webs, one phytoplankton based and one
bacteria based, was studied in a mesocosm experiment using seawater from the northern …

While consumer species diversity is known to influence the capture of limited resources, little
is known about how prey diversity impacts the transfer of energy and matter among trophic …

In order to evaluate the effects of inducible defences on community stability and persistence,
we analyzed models of bitrophic and tritrophic food chains that incorporate consumer …
