“…When the pressure exceeds the resistance of the community, for instance considerable species loss will occur. Such threshold responses of benthic macrofauna has previously been described in relation to hypoxia (Diaz and Rosenberg, 1995;Levin and Gage, 1998), organic enrichment in general (Hyland et al, 2005), and sediment metal contamination (Burd, 2002;Josefson et al, 2008).…”

“…Pearson and Rosenberg (1978) have generalised the benthic faunal changes along such gradients of organic enrichment and oxygen deficiency, and listed benthic species that are sensitive or tolerant to various degrees of disturbance. However, there are only few studies of faunal community response to heavy metals (Josefson et al, 2008), and metal pollution often occur in association with organic enrichment (Swartz et al, 1985). The structure of the benthic fauna is one of the quality elements used in "The EU Water Framework Directive" (WFD; 2000/60/EC) to assess the benthic Ecological Quality Status (EcoQS) in Europe.…”

“…Being crushed rock, the gradient is likely a pure metal gradient with lead, zink and to some extent copper as dominating heavy metals. Tailings were disposed at 40 m depth in the inner fjord arm which had a maximum depth of 70 m. Macrobenthic species abundance and surface sediment metal concentrations where measured at 16 stations, in the tailings area and outside, before, during and 15 years after termination of tailings disposal activities, following a BACI sampling protocol (Johansen et al, 2006;Josefson et al, 2008) The resulting material used here was ca 150 paired faunal and sediment metal (Pb) samples.…”

“…Moreover, some additional research is needed in the coming years (see Borja et al, 2009e), including the need to take physical disturbances into account (e.g., dynamic forcing of the systems) and to favor multicriteria approaches, including the indices that are based on the struc ture and production of the communities, in the development of an operating report. Moreover, testing indices with different human pressures are being undertaken in some cases (Calabretta and Oviatt, 2008;Chainho et al, 2008;de Paz et al, 2008a;Josefson et al, 2008;Thrush et al, 2008;Borja et al, 2009d;de-la-Ossa-Carretero et al, 2009), but more tests are needed. Finally, when using indicators and indices, investi gators should be as pragmatic as possible in making them environmentally sustainable, economically viable, technologi cally feasible, socially desirable/tolerable, legally permissible, and politically expedient.…”

There is an increasing need in assessing ecological quality and integrity of estuaries and lagoons. This chapter shows the most recent efforts in assessing individual biological elements (from phytoplankton to fishes), together with the integrative tools developed in different geographical areas worldwide. However, reducing complex information from multiple ecosystem elements to a single color or value is a substantial challenge to marine scientists, and requires the integration of different disciplines (chemists, engineers, biologists, ecologists, physics, managers, etc.), to reach agreement on the final assignment of ecological status. Hence, in the near future, emphasis needs to be directed at understanding the complexities of estuarine system functioning rather than simplifying and scaling down the system into smaller components.

“…Ballesteros et al, 2007;Muxika et al, 2007). Yet, also recognized is the importance of quantitative data for precision and accuracy, stressor-response relationships, 280 predictive modeling, and sound ecological theory (Magni et al, 2005a;Orfanidis, 2007;Josefson et al, 2008;Lyche Solheim et al, 2008). A significant challenge in assessing stressor-response relationship in transitional waters, such as estuaries and coastal lagoons, is that they are under the influence of multiple factors and have a great internal patchiness and heterogeneity, which can often bias the application of the most common indicators and indices of environmental quality and 285 health status (Dauvin, 2007;Elliott and Quintino, 2007;Ruellet and Dauvin 2007).…”

In the present study, we investigated the applicability of the Pearson-Rosenberg (P-R) conceptual model describing a generalized pattern of response of benthic communities in relation to organic 25 enrichment to a specific typology of marine systems, i.e. coastal lagoons. The study was performed with independent matching data on the structure of macrobenthic communities and total organic carbon (TOC) content of sediments obtained from 349 stations representing three of the most ecologically and economically relevant coastal lagoons in the Mediterranean Sea, i.e. the lagoons of Cabras, Orbetello, and Venice (Italy). Consistent with P-R model predictions, we 30 found two different peaks in benthic diversity and abundance at low (> 2.5-5 mg g -1 ) and high (> 25-30 mg g -1 ) TOC ranges, respectively. We identified TOC thresholds indicating that risks of reduced benthic diversity from organic loading and other associated stressors in sediments should be relatively low at TOC values < about 10 mg g -1 , high at TOC values > about 28 mg g -1 , andintermediate at values in-between. Predictive ability within these ranges was high based on 35 results of re-sampling simulation. Our results validate and support a prior independent study that identified similar TOC thresholds for assessing risks of benthic impacts in samples from seven coastal regions of the world. While not a measure of causality, it is anticipated that these TOC thresholds should serve as a general screening-level indicator for evaluating the likelihood of reduced sediment quality and associated bioeffects in such eutrophic systems of the 40 Mediterranean Sea, which also are exposed to a variety of stressors from multiple human uses.
