“…There has been considerable recent interest among conservation biologists in the identification of robust indicators of the state of ecological systems that can be readily incorporated into land monitoring and assessment programs (Noss 1990, Spellerberg 1993, McKenzie et al 1995. Attention has focused on the use of terrestrial invertebrates as bioindicators, because of their dominant biomass and diversity and their fundamental importance in ecosystem function (Disney 1986, Rosenberg et al 1986, Majer 1989.…”

“…Traditionally, bioindicators have been used to assess ecosystem responses to environmental perturbation, often associated with human land use (Noss 1990, Spellerberg 1993, McKenzie et al 1995. For 20 years, for example, the Australian mining industry has used ant species richness and composition as indicators of restoration success (Majer et al 1984, Andersen 1997a, and these protocols have been exported to Brazil (Majer 1992) and South Africa (Majer and de Kock 1992).…”

“…Among them, information on the trophic structure of the community reflects the effect of biotic interactions and energy flows, and complex interactions results from multiple pathways linking different ecosystem components (Carpenter, 1988). Among various indicators suggested to describe ecosystem status (Mckenzi et al, 1992), exergy is a unique and efficient expression of energy status in ecosystems (Jørgensen, 1997;Jørgensen and Mejer, 1977). It is an effective measurement 0304-3800/$ -see front matter © 2005 Elsevier B.V. All rights reserved.…”

a b s t r a c tExergy is a measure of the free energy of a system with contributions from all components including the energy of organisms, and it is used as an ecological indicator. In this study, we implemented a self-organizing map (SOM) for patterning exergy of benthic macroinvertebrate communities. The datasets were extracted from the database EKOO consisting of 650 sampling sites in the Netherlands including 855 species. Using these datasets, exergy of five trophic functional groups (carnivores, detritivores, detritivore-herbivores, herbivores, and omnivores) were calculated for each sampling site on the basis of the biomass data.Exergy of each trophic group was used as input data of the SOM. By training the SOM the sampling sites were classified into five clusters and the classification was mainly related to water types of the sampling sites. Exergy of different trophic groups responded differently to different water types displaying characteristics of target ecosystems. Finally, the results show that exergy is an effective ecological indicator and patterning changes of exergy is an effective way to evaluate target ecosystems.

“…Ecologists have long sought concise and cost-effective measures that can characterize ecosystem conditions (Rapport et al 1985, Shaeffer et al 1988, McKenzie et al 1992, Griffith and Hunsaker 1994, Munasinghe and Shearer 1995, Karr and Chu 1997, but data collection and analysis are only part of an effective effort using indicators. With the increased use of indicators for community sustainability initiatives (Walter and Wilkerson 1994), national economic and policy decision making (Straussfogel 1997), international development work (O'Conner et al 1995), and environmental assessments (Suter 1990(Suter , 1993, one key element that emerges repeatedly is the need for effectively communicating technical information from and about indicators to diverse users (McDaniels et al 1995, Slovic 1995, Ward 1999.…”

“…EMAP indicators make a good case study because they are representative of the types of indicators proposed by a number of ecological monitoring programs (McKenzie et al 1992, Organization for Economic Cooperation and Development 1994, Syers et al 1995, Levy et al 1996. Furthermore, EMAP indicators are attractive for our purposes because they come from different disciplinary lineages, focus on divergent aspects of ecosystems, and use different aggregation and naming conventions.…”

Communicating Ecological Indicators to Decision Makers and the Public

Ecological assessments and monitoring programs often rely on indicators to evaluate environmental conditions. Such indicators are frequently developed by scientists, expressed in technical language, and target aspects of the environment that scientists consider useful. Yet setting environmental policy priorities and making environmental decisions requires both effective communication of environmental information to decision makers and consideration of what members of the public value about ecosystems. However, the complexity of ecological issues, and the ways in which they are often communicated, make it difficult for these parties to fully engage such a dialogue. This paper describes our efforts to develop a process for translating the indicators of regional ecological condition used by the U.S. Environmental Protection Agency into common language for communication with public and decision-making audiences. A series of small-group sessions revealed that people did not want to know what these indicators measured, or how measurements were performed. Rather, respondents wanted to know what such measurements can tell them about environmental conditions. Most positively received were descriptions of the kinds of information that various combinations of indicators provide about broad ecological conditions. Descriptions that respondents found most appealing contained general reference to both the set of indicators from which the information was drawn and aspects of the environment valued by society to which the information could be applied. These findings can assist with future efforts to communicate scientific information to nontechnical audiences, and to represent societal values in ecological programs by improving scientist-public communication.
