Aquatic ecosystem metabolism as a tool in environmental management

WIREs Water, 2021
Recent advances in high‐frequency environmental sensing and statistical approaches have greatly expanded the breadth of knowledge regarding aquatic ecosystem metabolism—the measurement and interpretation of gross primary productivity (GPP) and ecosystem ...

Microplastic in Aquatic Ecosystems

Angewandte Chemie International Edition, 2016
AbstractThe contamination of marine and freshwater ecosystems with plastic, and especially with microplastic (MP), is a global ecological problem of increasing scientific concern. This has stimulated a great deal of research on the occurrence of MP, interaction of MP with chemical pollutants, the uptake of MP by aquatic organisms, and the resulting ...

Assessing aquatic ecosystem health through the analysis of plankton biodiversity

Marine and Freshwater Research, 2019
Healthy plankton communities are the foundation of many freshwater food webs. Their biodiversity is often used to directly reflect the health of the rivers.

Aquatic Ecosystems

2008
Concern about future supplies of fresh water to society, to meet the full range of human needs, now comes very high on the priority list of global societal issues. An overarching issue, which this book addresses, is whether global climate change is a dominant driver of change in the structure and function of all natural water-based ecosystems, or ...

Aquatic ecosystem profile

2007
This chapter considers the White Sea ecosystem, paying special attention to the food web connections that are continuously establishing between the main bird and mammal species. The White Sea ecosystem is complicated, as each of its levels is characterized by numerous trophic ties that vary in the annual cycle and depend on the current environmental ...

Nitrogen in Aquatic Ecosystems

AMBIO: A Journal of the Human Environment, 2002
Aquatic ecosystems respond variably to nutrient enrichment and altered nutrient ratios, along a continuum from fresh water through estuarine, coastal, and marine systems. Although phosphorus is considered the limiting nutrient for phytoplankton production in freshwater systems, the effects of atmospheric nitrogen and its contribution to acidification ...

Digitalizing river aquatic ecosystems

Journal of Environmental Sciences
Traditional river health assessment relies on limited water quality indices and representative organism activity, but does not comprehensively obtain biotic and abiotic information of the ecosystem. Here, we propose a new approach to evaluate the ecological and health risks of river aquatic ecosystems.
