Discriminating mesozooplankton communities in Bushehr marine coastal ecosystems- Persian Gulf
Coastal ecosystems of Bushehr are shallow environments subject to human impacts, including shrimp aquaculture and urban expansion activities. A spatial-temporal study was conducted in order to assess the actual ecological status of the creeks, estuary and marine sites on the basis of their taxonomic composition and density of mesozooplankton. Zooplankton species distribution and abundance data ...

متن کاملNitrogen saturation in stream ecosystems.
The concept of nitrogen (N) saturation has organized the assessment of N loading in terrestrial ecosystems. Here we extend the concept to lotic ecosystems by coupling Michaelis-Menten kinetics and nutrient spiraling. We propose a series of saturation response types, which may be used to characterize the proximity of streams to N saturation. We conducted a series of short-term N releases using a...
متن کاملThresholds for the effects of pesticides on invertebrate communities and leaf breakdown in stream ecosystems.
We compiled data from eight field studies conducted between 1998 and 2010 in Europe, Siberia, and Australia to derive thresholds for the effects of pesticides on macroinvertebrate communities and the ecosystem function leaf breakdown. Dose-response models for the relationship of pesticide toxicity with the abundance of sensitive macroinvertebrate taxa showed significant differences to reference...
متن کاملCommunities and Ecosystems
translation yields a style of presentation that is often stilted and awkward. A partially redeeming feature, and perhaps unique in this kind of publication , is a 60-question-and-answer chapter which gives a rapid and practical orientation to the physician prescribing these pills and the patient receiving them. Despite this pleasant surprise, the book in general does not add to what is already ...
