The evaluation of the impact of gradual environmental changes, such as the salinization of freshwaters, requires measures that are sensitive enough to detect the subtle changes that may be occurring within a population. Fluctuating asymmetry (FA) has been used widely to investigate questions regarding fitness and behavior, and to study the effects of environmental pollution. Asymmetries in the femur lengths of Calopteryx splendens (Odonata) larvae, and in the femur lengths, the tibia lengths and the pygopod widths of Hydropsyche exocellata and H. contubernalis (Trichoptera) larvae were studied at three sites along a salinity gradient of the Meurthe River (France). The difference in salinity between the sites (ranging from 0.21 to 2.60 g.L−1) was the only parameter varying to a degree significant enough to potentially affect damselfly or caddisfly development and their population densities. While no directional asymmetry or anti-symmetry was found, fluctuating asymmetry was observed for each species, each ...

The need to have exhaustive data available for environmental assessment is contrary to the local character of the measurement methods for most environmental monitoring programs. Against this background, the spatial transferability of data from the German Environmental Specimen Banking Program (German ESB) was investigated by creating a model that predicts polycyclic aromatic hydrocarbon (PAH) concentrations for sites with missing monitoring data. In particular, we tested if data measured in one representative of a certain ecosystem type may be transferred to further representatives of the same ecosystem type. Modelling was based on real polycyclic aromatic hydrocarbon pollution and on the fundamental assumption that the ecological structure of an ecosystem has a dominant impact on pollutant concentrations. To manage the complexity of processes and factors influencing the pollution of ecosystems, which are far from well-known, artificial neural networks (ANNs) were used to generate a suitable estimation mo...

Coastal systems are ecologically important environments due to their diversity and productivity, but they can also serve as sinks for pollutants transported via runoff and atmospheric deposition. Grass shrimp, of the genus Palaemonetes, are a common inhabitant of East and Gulf coast estuaries of the United States and are proposed in this paper as a bioindicator of human impacts on estuarine systems. Using grass shrimp as such would involve their entire life cycle and consist of biomonitoring studies, in situ and laboratory toxicity tests, and development of biomarkers of exposure. The current interest in developing ecological indicators has put a renewed relevance on grass shrimp research. This paper reviews ecologically based studies, toxicity testing, and sublethal assessments in grass shrimp and shows how they have laid the groundwork for this genus to be an indicator species. It is concluded that correlating traditional grass shrimp assays with ecological monitoring and biomarkers of exposure is a goa...

Within the framework of the litterfall chemistry subprogram of the integrated monitoring program, litterfall was collected, and the concentrations of Ca, Mg, K, Pb, and Zn were measured during 1999–2003 at the Taurene and Rucava monitoring stations in Latvia. The results showed that at Rucava there was higher production of litterfall than at Taurene due to a higher tree density. The mean annual litterfall was 3630.42 kg/ha−1 in Rucava and 3022.11 kg/ha−1 in Taurene, with maximum production in autumn at both sites. The litterfall production among the catchments varied seasonally because length of growing period, composition of tree species, and density of snow cover. The higher Ca, Mg, and K concentrations in Taurene were due to greater birch litter contributions and soil chemical properties. The higher Pb and Zn concentrations in the Rucava IM catchment can be explained by the influence of long distance transboundary air pollution and local sources. The chemical element concentrations showed seasonal vari...

Current levels of anthropogenic mercury (Hg) in the environment can cause harm to humans and wildlife. Well-documented negative effects on birds are described, but there is presently limited information for passerine exposure to mercury. Some investigations have used insect-eating birds as potential bioindicators of mercury exposure. However, our understanding of methlymercury (MeHg) availability to birds in coastal wetlands, tidal systems that may be especially conducive to Hg methylation, remains poor. Two species of sharp-tailed sparrow breed in coastal wetlands in eastern North America and are suitable candidate indicators for contaminants in these habitats. We measured blood Hg from breeding Saltmarsh (Ammodramus caudacutus) and Nelson’s (Ammodramus nelsoni) sharp-tailed sparrows in five Maine salt marshes to determine if these species could be used to assess the extent of MeHg availability in salt marshes. Blood Hg for both species differed among the five marshes with concordance between species and...

A wide range of scientists, managers, governmental agencies, and the public are interested in assessing the health and well-being of species, populations, and ecosystems. This has resulted in increased studies of the usefulness of different indicators as a measure of stressors and contaminants. This paper presents a review of bioindicators since 1970 by using four journals: Science of the Total Environment, Environmental Science and Technology, Environmental Pollution, and Ecotoxicology and Environmental Safety. The overall objective was to examine temporal trends in publications on bioindicators, the species used as bioindicators, the contaminants of concern, and what they indicated (e.g., pollution or air quality). Overall, there has been a steady rise in the publication of papers about indicators since 1970, with nearly 35% of the indicator papers published in the last 5 years. Most papers that use the term indicator or bioindicator deal with some form of pollution, environmental quality, or human heal...

Government, scientists, managers, and the public are interested in assessing the health of ecosystems. Initially ecologists concentrated on assessing condition, reproductive success, and survival of a wide range of individual species, but this approach quickly broadened to include the health of communities, ecosystems, and landscapes, as well as the human dimension. Monitoring ecosystem health requires the use of a suite of bioindicators that are biologically, methodologically, and societally relevant, and can be used effectively over time to assess trends and provide early warning. Bioindicators can be developed for ecosystem health assessment, for human effects and interventions, human health assessment, and for evaluating sustainability. Whereas ecologists initially developed indicators to measure health or well-being of relatively pristine environments, the usefulness of indicators is enhanced if they can assess both ecological and human health, provide trends data, and be used to examine a wide range...

Endocrine acting compounds dispersed into the environment have been reported to adversely affect growth and reproduction of wildlife. Some of the compounds are industrial by-products, but evidence points to sewage treatment plants as a major source of these contaminants. Typically whole life studies with vertebrates and invertebrates are performed to determine adverse health effects. This approach is ecologically sound, but may not point to the mechanisms by which the contaminants exert their effects. Molecular technologies have the potential to shorten the time of evaluation and provide integrated information to tie changes at the molecular level with adverse health effects. We describe molecular approaches that can be used to determine changes in gene expression patterns elicited by exposure to contaminants. Differential display RT-PCR and microarray analysis are powerful methods to measure the biological effects of exposure to environmental compounds. Both techniques need to be validated by quantitativ...
