“…In our analyses, there was no evidence that pollution influenced mussel population structure. This is perhaps surprising, given evidence of severe effects of some pollutants on mussel larvae (Hoare, Beaumont & Davenport 1995; Hoare, Davenport & Beaumont 1995). Nevertheless, the current evidence suggests that the relationship between SFG and community structure is probably driven by direct effects of pollution on the organisms associated with the mussels rather than by indirect effects mediated by changes in the habitat provided by the mussels.…”

Summary1. Due to the cost and complexity of sampling biological communities, surrogate biological measures or concentrations of toxic contaminants are often used to indicate environmental impacts. Such indicators can be powerful tools, but their effectiveness requires evaluation. Mussels are widely used as bioindicators of environmental contamination. For example, physiological measurements on live mussels form the basis of scope for growth (SFG), an integrated indicator of environmental stress. However, the effectiveness of SFG as an indicator of community level effects has rarely been tested in the field. 2. In this study of six sites on the west coast of the UK, the diversity of macrofaunal communities associated with mussels was reduced at sites with low SFG (< 10 J g) compared with those with high SFG (> 15 J g − 1 h − 1 ). At smaller scales, variation in community structure was related to biomass of mussels, mass of coarse sediments and the fractal dimension of the surface of the mussel bed. 3. We measured hydrocarbon contamination as a first step in identifying contaminants that might underpin the relationship between SFG and diversity. Unresolved complex mixtures (UCM) are often the most abundant hydrocarbon contaminants in the environment, but have, until recently, been largely ignored. We found generally good accordance between UCM concentration in mussel tissues, SFG and diversity, but other pollutants are also likely to be involved. 4. Synthesis and applications. Our findings illustrate the complexity of relating changes in diversity to synoptic or sublethal measures of environmental stress in the field. However, the results represent a significant step towards a biotic indicator of environmental quality that integrates impacts across a range of levels of biological organization (from intraindividual to community). Such indicators may be of particular value in the implementation of the European Union Water Framework Directive in Europe and similar environmental legislation elsewhere.

“…In some cases, field-collected adults were bred in the laboratory and the resulting F1 offspring were raised under common conditions for weeks to months before testing (e.g., Johannesson & Johannesson 1996). More commonly, F1 individuals were produced in the laboratory by spawning field-collected adults and were tested soon thereafter as larvae or juveniles (e.g., Ament 1979, Hoare et al 1995. These approaches likely reduce influences due to environmental history, although maternal effects may still influence traits measured in laboratoryreared offspring.…”

Local adaptation in the sea was regarded historically as a rare phenomenon that was limited to a handful of species with exceptionally low dispersal potential. However, a growing body of experimental studies indicates that adaptive differentiation occurs in numerous marine invertebrates in response to selection imposed by strong gradients (and more complex mosaics) of abiotic and biotic conditions. Moreover, a surprisingly high proportion of the marine invertebrates known or suspected of exhibiting local adaptation are species with planktonic dispersal. Adaptive divergence among populations can occur over a range of spatial scales, including those that are fine-grained (i.e., meters to kilometers), reflecting a balance between scales of gene flow and selection. Addressing the causes and consequences of adaptive genetic differentiation among invertebrate populations promises to advance community ecology, climate change research, and the effective management of marine ecosystems.

Changes in the Microelement Composition in Organs and Tissues of the Bivalve Crenomytilus grayanus Acclimatized in a Biotope with Long-Term Heavy Metal Contamination

This paper deals with changes in the Fe, Zn, Cu, Cd, Mn, Pb, and Ni concentration in the muscle, gonad, mantle, gills, digestive gland, and kidneys of Gray mussels transplanted from two sites differing in the extent of metal contamination to a biotope with the impact from anthropogenic conditions in the course of their acclimatization. The rate of metal accumulation depended on the initial element concentration in the mussel organs. An abrupt change in the metal concentration in the environment was followed by a disturbance in the microelement balance in some organs. The microelement metabolism was shown to depend on mussel preadaptation to a changeable environment.
