  • Environmental pressures and impacts of public sector organisations: the case of the Portuguese military

    Public institutions are beginning to realise that they must shift their management towards sustainability. Thus, public sector, including defence services, environmental performance evaluation is a growing reality. The main objective of this research was to assess the environmental pressures and impacts profile of the Portuguese defence sector. A questionnaire survey was conducted involving all ...

  • Can natural variability trigger effects on fish and fish habitat as defined in Environment Canada's metal mining environmental effects monitoring program?

    The Metal Mining Effluent Regulations (MMER) took effect in 2002 and require most metal mining operations in Canada to complete Environmental Effects Monitoring (EEM) programs. An “effect” under the MMER EEM program is considered any positive or negative statistically significant difference in fish population, fish usability, or benthic invertebrate community EEM‐defined endpoints. Two ...

  • Efforts to standardize wildlife toxicity values remain unrealized

    Wildlife toxicity reference values (TRVs) are routinely used during screening level and baseline ecological risk assessments (ERAs). Risk assessment professionals often adopt TRVs from published sources to expedite risk analyses. The United States Environmental Protection Agency (USEPA) developed Ecological Soil Screening Levels (Eco‐SSLs) to provide a source of TRVs that would improve ...

  • Attitudes of Europeans towards the issue of biodiversity

    The European Union (EU) is committed to the protection of 'biological diversity', i.e. the variability among living organisms from all sources including, inter alia, terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems1. The EU has been legislating on biodiversity since the ...

  • Withdrawal of fresh water may reduce aquatic diversity

    Withdrawing fresh water from rivers and streams may adversely affect the health of fish and aquatic insects, according to a research team studying correlations between the two in North Carolina. The researchers, charged by the state of North Carolina and the state’s Department of Environmental Quality, investigated the relationship between changes in surface water flow and the diversity of ...

  • Rainwater harvesting: theorising and modelling issues that influence household adoption

    Household adoption of rainwater harvesting (RH) systems recently boomed in Australian urban centres. As a sustainable supplement to the mains supply, water authorities regarded RH as a demand management device. Yet what actually motivated household RH adoption was not well understood. Burawoy's ‘extended case method’ was used to link grounded enquiry with 13 core theoretical concepts drawn from ...

  • Communication and the Narrative Basis of Sustainability: Observations from the Municipal Water Sector

    Numerous studies attempt to operationalize sustainability and seek to characterize objective, or at least standardized, metrics of sustainable conditions and/or operations. In this paper, we suggest that sustainability is better viewed as an emergent quality, defined in terms of specific institutions and situations. Observations from the water sector suggest that sustainability is not merely a ...

  • Sustaining interest: are green values converting to votes?

    Sustainability is fashionable and becoming more important to the general policy discourse on protecting the environment. However, despite the government's adoption of a National Strategy for Ecologically Sustainable Development some 12 years ago, Australia's performance on crucial items such as emissions of carbon dioxide equivalents remains poor. Arguably then, for the environmental cause to be ...

  • Metal Mixture Modeling Evaluation project: 2. Comparison of four modeling approaches

    As part of the Metal Mixture Modeling Evaluation (MMME) project, models were developed by the National Institute of Advanced Industrial Science and Technology (Japan), the U.S. Geological Survey (USA), HDR׀HydroQual, Inc. (USA), and the Centre for Ecology and Hydrology (UK) to address the effects of metal mixtures on biological responses of aquatic organisms. A comparison of the 4 models, as ...

  • Staying Safe with Environmental Monitoring

    Geotechnical Instrumentation involves administering the earth and environment and it is hence that designers have made different frameworks to make the occupation simpler. These frameworks grab thousands upon much information that it orders and illuminates so they can concoct evidence. The places where it is necessary are the pollution chance appraisal, trends in time and space; anticipatory ...

  • Thresholds of Contaminants: A Synthesis

    A fundamental problem in ecotoxicology is the prediction of population and ecosystem-level effects of contaminant exposure based on dose response data of individuals. Furthermore, long term effects are not assessed when analysing dose-response of few individuals over a short period of time and even no-effect dose concentrations could have a long term effect at population or at ecosystem level. In ...


  • The terrestrial ecosystem monitoring sites: a utility assessment

    Ecological research sites generate data which are potentially useful at the national, regional and global scales. However, most of the data remain embedded in local, project-specific research programmes. The primary role of the Global Terrestrial Observing System (GTOS) is to act as a data broker and bring researchers and modellers together in order to better understand global change processes in ...

  • The condition of coral reefs in South Florida (2000) using coral disease and bleaching as indicators

    The destruction of coral reef habitats has occurred at unprecedented levels during the last three decades. Coral disease and bleaching in the Caribbean and South Florida have caused extensive coral mortality with limited recovery, often coral reefs are being replaced with turf algae. Acroporids were once dominant corals and have diminished to the state where they are being considered as ...

  • Modelling Wetland Bird Response to Water Level Changes in the Lake Ontario – St. Lawrence River Hydrosystem

    Lake Ontario and St. Lawrence River (LOSL) wetland bird abundance and diversity are greatly influenced by lake and river hydrology. Our study used an interdisciplinary ecosystem approach, blending avian and plant ecology, ecohydraulic, statistical ecology and modelling to evaluate potential impacts of water level fluctuations on indicator species representative of the wetland breeding bird ...

  • A conceptual framework for US EPA’s national exposure research laboratory

    The challenges of environmental protection range from understanding the potential risk associated with exposure of humans and ecosystems to a newly manufactured chemical, to minimizing human exposure to pathogens at public beaches, to linking human activities on the landscape to physical alterations of ecosystems. In the United States, there are more than 75,000 industrial chemicals that are ...

  • Environmental restoration is big business
