The sustainable use of water resources requires clear guidelines for the management of
diffuse pollution inputs to rivers. Without informed guidelines, management decisions are …

1. In some shallow lakes, Daphnia and other important pelagic consumers of phytoplankton
undergo diel horizontal migration (DHM) into macrophytes or other structures in the littoral …

Habitat complexity is one of the most important factors structuring biotic assemblages, yet we
still lack basic understanding of the underlying mechanisms. Although it is one of the primary …

Over the last 40 years there has been substantial evidence that high biomasses of
submerged aquatic plants and phytoplankton rarely occur together in shallow lakes, but it is …

We investigated the effects of an exotic snail, the golden apple snail (Pomacea canaliculata)
on biodiversity and ecosystem functioning in tropical wetland ecosystems. This large snail …

We investigated the role of freshwater macrophytes as refuge by testing the hypothesis that
predators capture fewer prey in more dense and structurally complex habitats. We also …

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; …

The European Water Framework Directive requires the determination of ecological status in
European fresh and saline waters. This is to be through the establishment of a typology of …

Alternative equilibria dominated by either submerged plants or phytoplankton have been
described for communities in shallow lakes. A nutrient‐mediated increase in periphyton …

Dreissenid mussels (the zebra mussel Dreissena polymorpha and the quagga mussel D.
bugensis) are ecosystem engineers that modify the physical environment by increasing light …
