We assessed how a 5-yr nutrient enrichment affected the responses of different size classes of primary
consumers and predators in a detritus-based headwater stream. We hypothesized that alterations i...

We report the trophic structure of a myctophid assemblage by measuring theisotopic niches of 14 species living in Kerguelen waters, southern Indian Ocean. Most of the species show distinct isotopic ni...
No empirical evidence for community-wide top-down control of prey fish density and size by fish predators in lakes

Aquatic prey species respond to predators with fast (developmental) and slow (selective) feedbacks. Natural selection is assumed to fashion details of induction and to modify baseline morphology, but ...

Three antennule morphotypes in the small cladoceran Bosmina longirostris have been considered to be
hereditarily rigid phenotypes. However, we found that monoclonal populations of Bosmina collected f...
Selective predators and their parasitized prey: Are epidemics in zooplankton under top-down control?
Selective predators parasitized prey epidemics in zooplankton top-down control

The assumption that macrophytes can provide zooplankton a daytime refuge against fish predation is central to
the diel horizontal migration hypothesis. However, previous observations and experi...
