ABSTRACT Pollution significantly impacts aquatic biodiversity by limiting the species pool. However, considerable uncertainty remains regarding which community attributes should be used to demonstrate the effects of this anthropogenic disturbance. We propose that zooplankton taxonomic biodiversity could serve as a reliable pollution indicator in lentic

Read the free Plain Language Summary for this article on the Journal blog. Abstract Benthic suspension feeders like corals and sponges are important bioengineers in many marine habitats, from the shallow tropics to the depth of polar oceans. While they are generally considered opportunistic, little is known about their actual in situ diet.

The chaetognatha of the Eastropic Expedition, with notes as to their possible value as indicators of hydrographic conditions [PDF]
ENGLISH: The purpose of this study was to investigate the possibility that certain species of Chaetognatha found in Eastern Tropical Pacific waters can serve as biological indicators of oceanographic features. "Indicator" organisms have been found useful

Zooplankton richness, abundance and biomass of two hypertrophic shallow lakes with different salinity [PDF]
The zooplankton of lakes is controlled by biological and physico-chemical parameters. Among the former, predation by fish can determine the replacement of large-sized species by small-sized ones and among the latter, salinity exerts negative effects on ...
