This research examined effects of heavy metals on benthic macroinvertebrate communities
in the upper Arkansas River, Colorado. Benthic macroinvertebrates were collected …

Researchers have recently suggested that frequent prey dispersal into and out of an area
can swamp the local effect on predation. Where prey are mobile, the extent of prey …

Biodiversity goals are becoming increasingly important in stream restoration. Typical models
of stream restoration are based on the assumption that if habitat is restored then species will …

We studied the diet of the invasive round goby (Neogobius melanostomus) on a diel basis in
the Flint River, a warmwater stream in Michigan, USA Diet and available prey samples were …

La répartition spatio-temporelle et l'abondance relative des esturgeons jaunes (Acipenser
fulvescens) juvéniles et des macroinvertbrés benthiques ont été étudiées dans les rivières …

SUMMARY 1 This study attempts to determine the mechanisms by which the downstream
displacement of lotic invertebrates is compensated by the upstream movements of …

Classic island biogeographic theory predicts that equilibrium will be reached when
immigration and extinction rates are equal. These rates are modified by number of species …

Dispersal is an essential process which influences the effects of stream restoration on
aquatic insect communities, yet dispersal capabilities of many New Zealand taxa remain …

We examined the seasonal and diel patterns of invertebrate drift in relation to seston and
various habitat characteristics in two each of four different kinds of alpine streams [rhithral …

Theory and empirical work on food chains has focused primarily on closed, equilibrial
environments. We tested the combined effects of secondary consumers (fish) and limiting …
