Strength and time lag of relationships between human pressures and fish-based metrics used to assess ecological quality of estuarine systems

Dietary bioaccumulation of persistent organic pollutants in the common sole Solea solea in the context of global change. Part 1: Revisiting parameterisation and calibration of a DEB model to consider inter-individual variability in experimental and natural conditions.

“…Moreover, pollution has been identified as one of the main factors affecting the ecological quality of these areas, especially by altering their nursery function (see for instance Fonseca et al, 2014;Gibson, 1994;Nunes et al, 2014;Teichert et al, 2016). The effect of pollution in these habitats is such that, in Europe and especially in France, fish-based indicators of the ecological quality of transitional waters are particularly calibrated to respond to water contamination (Courrat et al, 2009;Delpech et al, 2010;Pasquaud et al, 2013).…”

Structuring cumulative effects assessments to support regional and local marine management and planning obligations

“…This temporal element is vital to CEA, particularly for CEAs seeking to identify how significant the introduction of additional stressors may be at a particular point in time. Metrics are thus required that are able to detect the strength and direction of effects on receptors and which are able to account for the time lags that are often present between a stressor being introduced and the emergence of effects [39]. Typical metrics, such as species richness, can miss impacts of anthropogenic stressors on the persistence and hence resilience of critical ecological features (e.g.…”

Developing a fish-based indicator to estimate the ecological status of transitional water in france for the Water Framework Directive: a fast but successful approach

“…Chaque pays européen a suivi une démarche de même type ain de mettre en place un réseau de surveillance de l'ichtyofaune et de développer des indicateurs de qualité écologique basés sur ces données de surveillance. Les méthodes d'échantillonnage varient beaucoup selon les pays (Nicolas et al, 2010a), tout comme les indicateurs retenus (Perez Dominguez et al, 2012 ;Pasquaud et al, 2013).…”
