  • Effects of iron on ecological communities

    Mark and I have been working with the Iron industry to try to understand the effects of iron on aquatic ecosystems. We have been analysing extensive field monitoring data on the quality of invertebrate communities in rivers and relating this to the levels of different forms of iron (total, dissolved, or particulate) that are present. Invertebrate communities do appear to be adversely affected ...

  • Community Based Ecological Monitoring in Nova Scotia: Challenges and Opportunities

    This article examines community-based ecological monitoring in Nova Scotia, with an emphasis on watershed stewardship groups. It discusses successes to date and future challenges, drawing on examples from the Atlantic Coastal Action Program (ACAP) and other community groups. The barriers to the generation of robust monitoring datasets and effective participation in watershed management are ...

  • Environmental benchmarks vs. ecological benchmarks for assessment and monitoring in Canada: Is there a difference?

    Environmental benchmarks are widely used in Canadian environmental assessment as a standard against which to monitor air or water quality in response to human activities in the environment. Recent work in Canada has developed the concept of ecological benchmarks as a complement to environmental benchmarks. However, implementation of ecological benchmarks may be challenging. This paper presents an ...

  • Diatoms for assessing the ecological condition of inland freshwater bodies

    The ecological responses of diatoms to pollution and nutrient enrichment, caused by domestic and municipal sewage, in the five fresh water ponds have been examined. It was observed that diatoms were completely absent in P3 and some species were also absent in P1 and P2. Similarly, diatom diversity was lower in P1 and P2 than in P4 and P5. However, diatom abundance was higher in P4. The Biological ...

  • Hydraulic “Fracking”: Are surface water impacts an ecological concern?

    Use of high‐volume hydraulic fracturing (HVHF) in unconventional reservoirs to recover previously inaccessible oil and natural gas is rapidly expanding in North America and elsewhere. Although hydraulic fracturing has been practiced for decades, the advent of more technologically advanced horizontal drilling coupled with improved slickwater chemical formulations has allowed extensive natural ...

  • Use of Phytoplankton Assemblages for Monitoring Ecological Status of Lakes within the Water Framework Directive: The Assemblage Index

    On basis of recent developments in phytoplankton ecology an assemblage index,Q,was developed to assess ecological status of di .erent lake types established by the Water Framework Directive (WFD).Since 5 ‡Q ‡0,the developed index can provide 5-grade quali .cation required by WFD.Case studies from very di .erent lake types support the usefulness of the developed index.Straights and weaknesses of ...

  • Linking feeding inhibition with reproductive impairment in Gammarus confirms the ecological relevance of feeding assays in environmental monitoring

    The in situ feeding bioassay in Gammarus fossarum is recognised as a reliable tool for monitoring the toxicity of freshwater contamination. However, whether recorded feeding inhibitions can potentially provoke population‐level adverse outcomes remains an open question. Here we present an experimental study in G. fossarum, which contributes to the quantitative description of the links between ...

  • Challenges for exposure prediction in Ecological Risk Assessment

    Evaluating organism exposure in the ecosystems is a difficult task and can be carried out measuring or predicting concentrations in the environment. While current regulatory approaches favour a modelling approach, they either use a static representation of the environment and of the chemical discharge or a simplified dynamic approach (e.g. dealing with pesticides). Improving the ecological ...

  • Bonanza Creek long term ecological research - 2009

    Like many research programs, our LTER site is continually struggling to manage numerous remote sensor stations and their data . We are constantly looking to improve the quality and availability of the data they are collecting while using technician time and resources effectively. One option on the market to manage sensor network data is Vista Data Vision (VDV) and after some initial testing, we ...

  • Opportunities and challenges of integrating ecological restoration into assessment and management of contaminated ecosystems

    Ecosystem restoration planning near the beginning of the site assessment and management process (“early integration”) involves consideration of restoration goals from the outset in developing solutions for contaminated ecosystems. There are limitations to integration that stem from institutional barriers, few successful precedents and limited availability of guidance. Challenges occur in ...

  • Hydro-ecological effects of changing Arctic river and lake ice covers: a review

    Freshwater ice is an integral part of the hydrologic regimes of cold environments. It controls the ecology of related aquatic systems and is important economically, through the facilitation of winter transport and via generation of extreme hydrologic events. Given projected changes in future climate, concern has been raised about related changes in freshwater ice. This paper reviews the status ...

  • Ecology of duckweed ponds used for nutrient recovery from wastewater

    The microorganism community that grows under duckweed shelter can play an important role on treatment processes. Therefore, the present study aimed to assess the zooplankton dynamic and microbial community in duckweed ponds (DPs) applied for domestic wastewater treatment under open field conditions. A pilot system comprised of two DPs in series (DP1 and DP2), with 10 m2 each, received domestic ...

  • Ecological Conditioning and Optimisation of a Once-Through Cooling Water System

    For the coming decade, Dow Benelux will need antifouling treatment for its cooling water system. Hypochlorite dosing is still considered to be the best available technology (BAT). This is based on proven effectiveness, large experience, moderate costs, opportunities to further optimise the chlorination procedure, and by the fact that in earlier studies low-level ...

  • Impact of operating history on mixed culture fermentation microbial ecology and product mixture

    Mixed culture fermentation is an alternative to pure culture fermentation for production of biofuels and valuable products. A glucose-fed, continuous reactor was operated cyclically to a central pH of 5.5 from a number of precedent pHs, from 4.5 to 7.5. At each pH, stable chemical production was reached after 2 retention times and was held for least 2 further retention times prior to the next ...

  • Ecological condition of wadeable streams of the interior Columbia river basin

    EMAP (Environmental Monitoring and Assessment Program) was initiated by EPA to estimate the status and trends of the nation's ecological resources and examine associations between ecological condition and natural and anthropogenic influences. The surface water component of EMAP is based on the premise that the condition of stream biota can be addressed by examining biological and ecological ...

  • Decision support for ecological river rehabilitation using fish habitat database

    After the recent success of several river rehabilitation projects including the Cheong-gye river case, a large number of local governments have been promoting their own projects in Korea. Most of the projects are aimed at securing the soundness of aquatic ecosystems according to the guidelines presented by the Korea Ministry of Environment. However, there is no clear guidance for the management ...

  • Evaluating groundwater/surfacewater transition zones in ecological risk assessments

    Currently, there is a common perception that the discharge of contaminated groundwater to a surfacewater body does not pose an ecological risk if contaminant concentrations in surface-water samples are below analytical detection limits or at very low concentrations. The transition zone represents a unique and important ecosystem that exists between surface-water and the underlying ground-water, ...

  • Prioritizing human pharmaceuticals for ecological risks in freshwater environment of Korea

    Pharmaceutical residues are potential threats to aquatic ecosystem. Since more than 3000 active pharmaceutical ingredients (APIs) are in use, identifying high priority pharmaceuticals is important for developing appropriate management options. Priority pharmaceuticals may vary by geographical region, as their occurrence levels can be influenced by demographic, societal, and regional ...
