  • Causes of ecological degradation in waterways

    Human activities can have a multitude of different effects on rivers and streams, and it is difficult to identify those that have the biggest impact on aquatic populations. A newly developed method for assessing ecological degradation in waterways helps deal with this problem and could provide crucial information for water managers charged with tackling the root causes of degradation. In the EU, ...

  • Urban water ecology

    Sewage overflows are a fact of life in urban areas, and in many cities, excess sewage water enters streams and lakes with rain runoff. Although this pollution is harmful to most organisms, there is one group of insects that thrives on it: mosquitoes. Luis Fernando Chaves, a post-doctoral researcher at Emory University, and his team discovered mosquitoes in abundance in a sewage-contaminated ...


  • Managing Ecological Investment Risk

    PORTLAND, Oregon, August 13, 2007 (ENS) - There is one complex term to describe our future: limited biocapacity. The Earth's limited biocapacity is the greatest challenge we face as investors and as humans. We are already facing it, but the severity of its effects depends on where you live and how much money you have. The planet provides some amazing ecosystem services for our ...

  • Ecological Catastrophe Overwhelms the Strait of Kerch

    A 'colossal' ecological catastrophe is growing even larger in the Strait of Kerch where at least 10 oil tankers and cargo ships loaded with sulfur were wrecked in a fierce storm on November 11. At least six sailors died in the wreckage. Now the storm in the Strait of Kerch is getting stronger, so it is not possible to stop the flow of oil into the sea and organize its collection and removal. ...

  • World is facing an ecological ‘credit crunch’

    The world is heading for an ecological credit crunch as human demands on the world's natural resources reach nearly a third more than earth can sustain. That is the stark warning contained in the latest edition of WWF’s Living Planet Report, the leading statement of the planet’s health. It shows that species and wildlife continue to decline, and around 50 countries are slipping into a state of ...

  • Cultivating Resilience in the Face of Ecological Change

    In the past decade, approximately 200–300 million people have been seriously affected by natural disasters or technological accidents each year—a staggering figure that is bound to only increase in the coming decades. It is becoming clear that a failure to make political systems pay attention to climate challenges might lead to massive population displacements. In State of the ...

  • Postdoctoral Fellow - Marine protistan ecology and evolution

    This position has a duration of one year, with a possible extension depending on job performance and funding. Microbes play fundamental roles in all ocean ecology. Our primary focus is on eukaryotic phytoplankton, and variations in the communities of bacteria, archaea and heterotrophic eukaryotes, as well as viruses, that accompany different phytoplankton taxa. To investigate these complex ...

  • IFCB in new Long-Term Ecological Research Site

    Imaging FlowCytobot samplers (IFCBs) manufactured by McLane will be installed in a new Long Term Ecological Research (LTER) site off the Northeast coast of the United States. LTER programs focus attention on specific sites representing major ecosystem types, and undertake long-term assessments of populations, communities, and the physical environment. ...

  • Collecting data to explore the ecological threat of nanomaterials

    The overall ecological impact of 10 engineered nanomaterials has been modelled for the first time using toxicity data from multiple living species. These models will allow researchers to assess the effect nanomaterials may have on both ecosystems and people. Engineered nanomaterials (ENMs) are small-scale substances measuring less than 100 nm in at least one dimension. They are increasingly used ...

  • Micro wind turbines and wildlife: integrating plaplanning with ecology

    The ecological impacts of micro wind turbines (up to 50 kW) are treated in a diverse way by different local authorities in the UK during the planning approval process, research suggests. The study calls for ecologists, policymakers, planners and industry representatives to improve the integration of ecological information within planning, and for greater guidance for local authorities on the ...

  • Can the Dutch National Ecological Network meet its goals?

    Ecological networks connect areas of habitat to prevent biodiversity loss and have been established across Europe. The ambitious Dutch National Ecological Network aims to span 728 500 hectares by 2025. In this study, researchers explored the feasibility of this goal in the context of climate and policy changes. Biodiversity loss continues worldwide. Ecological networks aim to halt this process ...

  • Assistant Professor - Freshwater Ecology and Conservation - Department of Environmental Science, Policy, and Management

Possible areas of emphasis for this position would include: freshwater population, community, or ecosystem ecology conservation of freshwater species and populations bio-indicators for freshwater ecosystem health and restoration ...

  • Link discovered between extreme weather event and marine ecological change

    Plymouth scientists have discovered evidence of a direct link between extreme weather events associated with climate change and episodic changes to the ecological conditions and processes of the marine environment of the Western English Channel. These modifications could have significant implications on how our coastal seas function in the future and ultimately, on the goods and services provided ...

  • New tool to assess the ecological impacts of offshore wind turbines

    How do offshore wind farms affect marine wildlife? A new study outlines a systematic approach developed for Swedish waters that could also be useful for assessing wind energy impacts on the marine environment more widely. Under the 20-20-20 targets, the EU is committed to increasing the proportion of its energy that is produced from renewable resources to 20% by 2020. To address this challenge, ...

  • Loss of Top Animal Predators has Massive Ecological Effects

     "Trophic Downgrading of Planet Earth," a review paper that will be published on July 15, 2011, in the journal Science, concludes that the decline of large predators and herbivores in all regions of the world is causing substantial changes to Earth's terrestrial, freshwater, and marine ecosystems. The paper claims that the loss of apex consumers from ecosystems "may be ...
