“…Stream mesocosms similar to those evaluated in this study are used routinely in studies of running waters, and whilst assessments of their physicochemical and ecological realism are necessary to validate experimentation, studies are scarce (but see Belanger, 1997;Richardson & Kiffney, 2000). In this case study, we found that basic physicochemical conditions in mesocosms corresponded closely to those of the source stream.…”

Realism of model ecosystems: an evaluation of physicochemistry and macroinvertebrate assemblages in artificial streams

Ecological realism is an important yet rarely reported feature of model ecosystems. In this case study, we assess the realism of four outdoor artificial stream mesocosms (4 m 2 ) bordering a chalk river in southern England. Comparisons of physiochemical conditions and benthic macroinvertebrate assemblages were made between the mesocosm units and the parent water body, a side arm of the River Frome. Physicochemistry of the mesocosm replicates was similar to that of the source stream, with congruent temporal variation evident between the real system and each of the models. The high realism of the mesocosms was explained by the outdoor location and close physical proximity of the array to the source stream, and the short mesocosm residence time of water sourced from the parent feeder system. Mesocosms supported a diverse array of benthic macroinvertebrates (60 families from 14 taxonomic orders), including all macroinvertebrate families in the source stream. Individual mesocosms contained a mean of 89% of source stream biota. We conclude that once-through mesocosms can be satisfactory analogues of natural systems, particularly where model and natural scales overlap.

“…Furthermore, large freshwater ecosystems usually are characterized by a diversity of habitats differing in abiotic and biotic properties (e.g., the pelagic or the littoral zone of lakes), whereas most artificial aquatic ecosystems usually simulate one of these habitats only. Belanger (1997) analyzed data from more than 150 studies using model stream ecosystems ranging in size from 0.2 to 540 m in length, 0.05 to 4.3 m in width, and 1.5 to 8 3 10 5 L in volume. He concluded that although larger systems could be sampled more intensively and were more likely to contain fish, no relationship existed between test system size and species richness of invertebrate, algal, or protozoan assemblages.…”

This discussion paper presents a framework for spatiotemporal differentiation in ecological protection goals to assess the risks of pesticides in surface waters. It also provides a proposal to harmonize the different scientific approaches for ecotoxicological effect assessment adopted in guidance documents that support different legislative directives in the European Union (Water Framework Directive and Uniform Principles). Decision schemes to derive maximum permissible concentrations in surface water are presented. These schemes are based on approaches recommended in regulatory guidance documents and are scientifically underpinned by critical review papers concerning the impact of pesticides on freshwater organisms and communities. Special attention is given to the approaches based on standard test species, species sensitivity distribution curves, and model ecosystem experiments. The decision schemes presented here may play a role in the ''acceptability'' debate and can be used as options in the process of communication between risk assessors and risk managers as well as between these risk experts and other stakeholders.

“…This diversity also makes the system useful in extrapolation to the "eld, with many of the most important taxa found with broad geographic distribution (Dyer and Belanger, 1999). Belanger (1997), Belanger et al (1995), and Dyer and Belanger (1999) clearly demonstrated the relative sensitivity of the ESF population and community structure which is useful in establishing the application of low uncertainty factors to results from the ESF. Rationales developed by Crossland et al (1992), van de Plaasche et al (1999), andVersteeg et al (2002) demonstrate that model ecosystem tests possessing high-quality data can be directly applied to predict concentrations of chemicals in the environment that present low risk to aquatic biota.…”
