“…For example, Wiberg-Larsen (2004) created a database on the larval head width, first and last week as well as duration of the flight period (all numeric descriptions) and the functional feeding groups (categorical descriptions) of Danish caddisfly species to relate these traits to stream width and the presence of a riparian forest. Likewise, Liess & Von der Ohe (2005) created a database at the species level including three biological traits (generation time, migration ability and aquatic stages in summer) of many European invertebrates to assess their risk of being affected by pesticides. Finally, Baird & Van den Brink (2007) started to assemble species traits of freshwater invertebrates to use them in predictions of species sensitivity to toxic substances.…”

Can biological invertebrate traits resolve effects of multiple stressors on running water ecosystems?

SUMMARY1. Accurately assessing the effects of multiple human-caused stressors on freshwater (and other) ecosystems is an essential step in the development of efficient decision support tools for environmental managers. Our objective is to review potentials and limitations of the use of biological traits as indicators (BTIs) of multiple stressor effects on running water (i.e. lotic) ecosystems. 2. Pioneers in ecology provided mechanistic explanations for responses of alternative biological traits to a given stressor and for the action of habitat harshness as a trait filter. These ideas were subsequently integrated in theoretical ecological constructs (e.g. Habitat Templet Concept) that form the basis of the BTI approach. 3. To resolve the effects of multiple stressors on running waters requires multiple traits of a biologically diverse group of organisms such as lotic invertebrates. To meet this goal, however, recently created databases on the biological traits of lotic invertebrates must be expanded and unified. 4. Addressing the technical implementation of the BTI approach, we illustrate that anticipated problems with phylogenetic trait syndromes are seemingly less serious in reality and that presence-absence data of genera and few sample replicates are sufficient for accurate trait descriptions of invertebrate communities. 5. Current trends in politics demand that biomonitoring tools be effective at large scales, i.e. large-scale trait patterns of natural communities (i.e. at reference conditions) should be relatively stable. The trait composition of natural invertebrate communities is relatively stable at the scale of Europe and North America because trait filters of natural lotic habitats act similarly across large biogeographical units. 6. The mechanistic actions of stressors on the biological traits of invertebrates should facilitate a priori predictions, but the complexity of potential trait responses makes such predictions sometimes difficult. 7. To illustrate potentials and limitations of BTIs to identify a given stressor acting exclusively (or primarily), we examine the (i) use of functional feeding groups to indicate the action of various stressors and (ii) trait responses to an indirectly acting stressor (discharge variation) and to a more directly acting stressor (near-bottom flow). If the excessive use of specific traits for the indication of too many different stressors is avoided and a given stressor acts directly on traits as a priori predicted, reliable interpretations of trait responses can be achieved. Thus, the BTI approach has the potential to inaugurate a new era in the biomonitoring of lotic (and other) ecosystems.

“…For a practical application in ERA, the vulnerability concept should be expressed in quantitative terms. Some tools capable of quantifying the vulnerability to specific stress factors have already been developed and proposed, particularly for freshwater ecosystems [48,49]. The development, application and validation of methods capable of assessing the vulnerability of aquatic and terrestrial ecosystems to different kinds of stressors is a priority for research.…”

Abstract:The usual procedures for ecological risk assessment (ERA) have been based for decades on simplified approaches in order to provide basic information on the huge amount of chemicals introduced into the environment. These approaches allowed the development of international regulatory tools capable of substantially reducing the adverse effects on ecosystems in developed countries. Nevertheless, these approaches suffer from a lack of ecological realism and are poorly suitable for understanding the actual consequences for ecosystem health. The need for more ecologically-based approaches is now recognized by the scientific community and has been highlighted by a recent document of the European Commission. In this paper, a synthesis is presented of the most important issues and the need for research to improve the ecological realism of exposure and effect assessment and the tools that should be developed to reach this objective. In particular, the major challenges are the following: the effects of variable exposure patterns; the vulnerability of ecosystems; the indirect ecological effects; the responses to multiple stress factors; the improvement of ecological modeling. The possibilities for using new scientific achievements in regulatory ERA are also discussed.

“…This approach was adopted to study the effects of toxic contamination on invertebrate communities in running waters [15][16][17]. It was shown that tolerant taxa are characterized by resistance and resilience traits [e.g., high mobility (which permits avoidance of exposition and dispersion) and short life cycles (which allow rapid re-colonization after disturbance)].…”

“…Riverine invertebrate communities have been extensively studied in response to gradients of contamination, producing effective toxicity indices [15][16][17]. By contrast, benthic communities in lakes have still been rather neglected, since the ecological status of lentic ecosystems has for long been assessed on the basis of only chemical and physical parameters.…”

The Water Framework Directive (2000/60/EC) is an innovative piece of legislation aimed at protecting the quality of all continental and coastal waters in Europe through an ecological evaluation of the ecosystems. Since it is widely acknowledged that the greater the ecological realism the greater the difficulty of its definition, we describe the different uses of benthic organisms as a tool for assessing the quality of sediment in lakes. We review the responses from single species to the community. We focus on studies in the laboratory and in the field, and we also critically consider the use of predictive models for these evaluations.Our discussion of the information collected underlines the importance of the relation between sensitivity of single species and contaminants. Moreover, the recent approach in developing mechanistic models to predict the response of natural communities seems to be particularly powerful for community ecology, and we strongly recommend more effort along these lines. ª
