  • 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 ...

  • 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 ...

  • 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 ...

  • Book Reviews: Eco-Global Crimes: Contemporary Problems and Future Challenges

    Keywords: eco-crimes, green criminology, environmental crime, animal rights, eco-global criminology and transboundary ecological damage The rapid and accelerating global deterioration in ecosystem health revealed by surveys such as the Millennium Ecosystem Assessment presents a serious threat to the well-being of humanity and of many other species with which it shares planet Earth. A wide ...


  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...


  • Asian Facility Project - Case Study

    Clients Three universities from China: the Xi’an Centre of Geological Survey, China University of Geosciences in Beijing and the Hohai University in Nanjing have set up the Asian Facility Project in cooperation with the UNESCO-IHE Institute for Water Education in Delft and Eijkelkamp Agrisearch Equipment. Project name Asian Facility Project ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Combining LiDAR and IKONOS data for eco-hydrological classification of an ombrotrophic peatland

    Received for publication March 11, 2009. Remote sensing techniques have potential for peatland monitoring, but most previous work has focused on spectral approaches that often result in poor discrimination of cover types and neglect structural information. Peatlands contain structural 'microtopes' (e.g., hummocks and hollows) which are linked to hydrology, biodiversity and carbon sequestration, ...

  • Environmental restoration is big business

    Think environmental protection hurts business? You just might want to think again. In a study published last week at PLOS ONE, University of North Carolina land use and environmental planning faculty member Todd BenDor and colleagues calculated the dollars-and-cents impact of ...

  • Socio-Economic Valuation of the Goods and Services of the Paraná Delta Wetland

    Environmental problems can be analysed from different complementary points of view, from the perspectives of both the exact and natural sciences and the social sciences. From an economic point of view, one issue that often receives attention is the resource-allocation decisions that are taken by people, since these are what result in nature being cared for or damaged. In order to make the ...

  • Risk perceptions are essential in communicating about climate change

    Experts and members of coastal communities possess both differences and similarities in how they perceive the risks associated with changes in sea level. A new study, based on interviews with both, has found that future communication about the risks should focus on specific adaptation and mitigation strategies. The Severn Estuary in the southwest United Kingdom has the second largest tidal range ...
