The European Commission recently proposed to protect vertebrate wildlife using hazard-based approaches for regulating pesticides with endocrine-disrupting properties. Researchers are familiar enough with using lab-based studies to test whether chemicals cause adverse effects in the usual animal models, but how do we identify those substances that will have adverse effects at the population level? Mark Crane and co-authors present an approach for evaluating protection goals for these compounds based on population responses within an ecosystem services framework. Read More »

The world’s growing population increases the already heavy demand on mineral resources on land, and so people are looking once more to the minerals found on the ocean floor, sometimes buried thousands of meters below the surface. The November 2018 issue of IEAM contains a critical review that explores the complexities of deep-sea mining, including the environmental, legal, economic, and societal impacts. In this episode we speak with lead author Andrea Koschinsky to learn more about this fascinating topic and the long road ahead to make it a reality.

The concept of resilience has been discussed in ecology since the 1970s, but practitioners are now applying the concept to improve accuracy and realism in ecological risk assessments. The September 2018 issue of IEAM features invited commentaries that discuss ecological resilience and what it means in practice for risk and impact assessments. Join us as we talk with authors Marco Vighi and Andreu Rico about how to incorporate resilience into ecological risk assessment, and the challenges and opportunities facing the regulatory community.

At your service! Linking healthy ecological function to human well-being, with Wayne Munns

We benefit from ecosystem services (ES) everyday—the water we drink, the food we eat, even the vacation at the beach. It is widely recognized that we need to protect the ecological processes that deliver these benefits, yet ES have not yet been formally incorporated into environmental risk assessment, one of the primary methods that inform regulatory decision making. Wayne Munns discusses the reasons for and challenges to the routine inclusion of ES endpoints in ERAs. Access the article in the July 2016 issue of IEAM.

For What It’s Worth: Using the Ecosystem Services Concept in Ecological Risk Assessments, with Valery Forbes and Peter Calow

The environmental community is abuzz with the concept of “ecosystem services.” But what does it really mean? And does this new way of thinking change how scientists approach environmental management? In this episode, Valery Forbes and Peter Calow provide an informal overview of how regulatory agencies can better incorporate the ecosystem services concept into ecological risk assessments (ERAs). Although agencies in Europe and the US have begun to integrate ecosystem services into ERAs, Forbes and Calow point out major challenges that must be overcome in order to substantially improve current ERA processes. Their article “Use of the ecosystem services concept in ecological risk assessment of chemicals” is part of the special series “Ecosystem Services: From Policy to Practice.” Access the series in the April 2013 issue of IEAM.
