1. Facing the necessity of describing estuarine ecosystems: a review of food web ecology study techniques

Author:
Pasquaud, Stéphanie; Lobry, Jérémy; Elie, Pierre

Subject:
biomarkers; ecosystems; energy; food webs; humans; models; organic matter; stable isotopes; stomach
Abstract:
... Estuarine areas are sites of human pressures and degradation. In order to maintain and/or restore the quality of estuarine ecosystems, it is necessary to describe their structure and functioning. For that reason, many recent scientific works focus on food webs, which are depicted as being good indicators of the functioning of aquatic ecosystems. Hence it is necessary to question how estuarine food ...

Abstract:
... The Schelde estuary, characterised as a turbid, polluted and eutrophic system, has nowadays reached a turning point in the restoration of its water quality. During the past century, human activities have reduced the intertidal areas, essential in the estuarine ecosystem for nutrient cycling and the self-cleaning capacity. Today, in combination with a master plan to protect the population from stor ...

Abstract:
... Industry represents about 31% of the upper Normandy region total value-added against 19.5% at national level. The same holds for the employment, since industry accounts for 21% of total local jobs, against 18% at national level. This article attempts to answer the following question: can we explain this specific concentration of economic activity by the natural advantages (water availability, easy ...

Abstract:
... The Bay of Seine is a potentially important nursery ground, especially for flatfish. This area, however, is also strongly anthropogenically influenced. A composite approach was chosen to compare the flatfish nursery function of the Seine estuary with other coastal and estuarine areas and to determine the impact of anthropogenic disturbances. It emerges that alteration of the nursery function in th ...
