Indicators of ecosystem recovery
Environmental Management, 1990Assessment of ecological changes relative to disturbance, either natural or human-induced, confronts a fundamental problem. Ecosystems are complex, variable, and diverse in nature; consequently, the need for simplification to essential features that would characterize ecosystems adequately is generally acknowledged.

ATP as a biomass indicator for closed ecosystems
Biosystems, 1983Nucleotide measurements have been used as biomass indicators in microbial ecology. We report the use of this metric in materially closed, energetically open microbial ecosystems. Our results indicate that: (i) both ATP concentrations and pO2 show an increase from time of closure; (ii) ATP concentrations (0.2 1.2 ng/ml) are approximately 2 3 times ...

Water quality indices as indicators of ecosystem change
Environmental Monitoring and Assessment, 1990The operational management of water quality requires a methodology that can provide precise information on cycles and trends in water quality in an objective and reproducible manner. Such information can be provided by the adoption of a water quality indexing system.

The strategy of ecosystem development: specific dissipation as an indicator of ecosystem maturity
Journal of Theoretical Biology, 2005The ratio of entropy generation rate to entropy embodied in structures relatively to the surroundings can be considered as an indicator of the ability of a self-organizing dissipative system to maintain itself far from equilibrium by pumping out entropy.

Svalbard reindeer as an indicator of ecosystem changes in the Arctic terrestrial ecosystem
Chemosphere, 2018Over the years, noticeable effort has been directed towards contaminant determination in multiple biotic samples collected from the inhabitants of the Arctic. Little consideration has been given to polar herbivores, however, especially those from the European parts of the Arctic.

Parasites of the superorganism: Are they indicators of ecosystem health?
International Journal for Parasitology, 2005The concept of ecosystem health is derived from analogies with human health, which subsequently leads to the implication that the ecosystem has organismal properties, a 'superorganism' in the Clementsian sense. Its application and usefulness has been the subject of a contentious debate; yet, the term 'ecosystem health' has captured the public's ...
