Aquatic science and the water framework directive: a still open challenge towards ecogovernance of aquatic ecosystems

Mercury in Aquatic Ecosystems—

Effects on aquatic ecosystems

Regarding the effects of UV-B radiation on aquatic ecosystems, recent scientific and public interest has focused on marine primary producers and on the aquatic web, which has resulted in a multitude of studies indicating mostly detrimental effects of UV-B radiation on aquatic organisms. The interest has expanded to include ecologically significant groups and major biomass producers using mesoco...

Mercury Contamination of Aquatic Ecosystems

Mercury has been well known as an environmental pollutant for several decades. As early as the 19501s it was established that emissions of mercury to the environment could have serious effects on human health. These early studies demonstrated that fish and other wildlife from various ecosystems commonly attain mercury levels of toxicological concern when directly affected by mercury-containing ...

Flow Characteristics of Aquatic Ecosystems

This contribution examines various flow measures based on analysis of 41 quantified models of trophic interactions in aquatic ecosystems. System productivity/biomass ratio is shown to relate to ecosystem maturity and to the degree of cycling in the systems. Distinct patterns or clusters are observed for different types of resource systems with respect to average path lengths and residence times...
