IEAM Podcast 23: Impaired Ecosystems: Ounce of Prevention or Pound of Cure? With Aida Farag & Ruth Hull. Although many people confuse the terms remediation and restoration, they are two separate processes in the restoration of impaired ecosystems. A special series in the April 2016 issue of IEAM challenges practitioners and researchers to rethink the traditional linear, sequential process of ecological restoration, instead encouraging a collaborative approach along the way, to integrate restoration goals throughout the process, beginning with site assessment. Guest Editors Aida Farag and Ruth Hull discuss workshop findings and tell us why we should heed an ounce of prevention when restoring ecosystems. Access the series in the April 2016 issue of IEAM.


IEAM Podcast 22: Get real! Stuart Hurlbert on pseudoreplication and other sins of statistical analysis Think you know stats? Stuart Hurlbert first described pseudoreplication—a common but serious statistical error—in 1984. Despite widespread knowledge of the error, pseudoreplication is often misinterpreted, and literature surveys show that the error is on the rise in certain fields. Listen to Hurlbert define pseudoreplication and other related errors, plus hear why we shouldn’t dichotomize results as “significant” and “non-significant,” what’s missing from basics stats courses, and what’s next on his list.

Brock Bernstein

IEAM Podcast 21: Oil’s well that ends well? Brock Bernstein talks rigs-to-reefs and the fate of oil platforms The 27 oil and gas platforms off the southern California coast are aging quickly. What’s next for an oil rig once it reaches the end of its useful life? Deciding the fate of these massive hulks of steel and machinery is no simple feat, and this podcast highlights the efforts by a team of authors that set out to do exactly that. In the special series “Offshore Platform Decommissioning in California,” Brock Bernstein and his co-authors evaluate the options for the aging platforms in southern California, which include some of the largest and deepest platforms ever built. Access the series in the October 2015 issue of IEAM

V. Castellani

IEAM Podcast 20: Reuse it or lose it! Using LCA to quantify the environmental benefits of reuse, with Valentina Castellani. “Going green” has become a sweeping campaign for consumers at all levels. One way to become more environmentally responsible is to practice reuse—the second of the three R’s in the mantra “Reduce, Reuse, Recycle.” Although reusing items such as clothing is easy to do, measuring the environmental benefits conferred by reuse is not as obvious as, say, a reduction in energy usage. Author Valentina Castellani used life cycle assessment to quantify the environmental impacts avoided by the reuse of commonplace items, through a secondhand store. Access her article in the July 2015 issue of IEAM.


IEAM Podcast 19: What’s in your toolbox? Julie Panko talks shop on tools for chemical assessment. Hazardous chemicals and consumer product safety garner tremendous public attention nowadays, and rightly so. The European Commission’s landmark REACh regulation set a high standard, and regulatory agencies around the world are moving towards chemical regulatory reform. The resulting need to characterize thousands of chemicals with regard to their hazard, risk, and exposure potential poses an enormous task, and dozens of chemical assessment tools have been developed to aid assessors. An article in the April 2015 issue of IEAM identifies the most robust and comprehensive tools used in chemical assessment. Co-author Julie Panko discusses how she and her fellow authors critically evaluated dozens of chemical assessment tools, to help assessors select the right tool for the job.

Dr Suzy Walls

IEAM Podcast 18: From the ashes: Using BERA to assess a coal fly ash spill in Tennessee, with Suzy Walls. The largest coal fly ash spill in US history occurred in 2008, at the Kingston Fossil Plant in Roane County, Tennessee. Over 4.1 million cubic meters of toxic coal fly ash spilled into the surrounding river ecosystem, which included three rivers and a reservoir. The January 2015 issue of IEAM features a special series of articles that detail the Baseline Ecological Risk Assessment (BERA) conducted to assess residual ash remaining in the Watts Bar Reservoir.

Dr Murray Rudd

IEAM Podcast 17: Survey says! Top PPCP research questions identified by environmental scientists, with Murray Rudd. Pharmaceuticals and personal care products (PPCPs) are a hot topic in environmental science. From synthetic estrogens that feminize male fish to concerns about resistance to antibiotics, this is a growing area of research and public attention. Yet potential and long-term effects on human and ecosystem health remain largely unknown. Author Murray Rudd leads an international study in the October 2014 issue of IEAM where environmental scientists identify their top PPCP research priorities. assessments.

Dr Sharon Hook

IEAM Podcast 16: Biomarkers for good measure: Assessing aquatic ecosystem status, with Sharon Hook. Biomarkers—biological endpoints long used in medical screening and disease detection—are finding new relevance in the environmental science community. Toxicologists have used biomarkers in certain aquatic contaminant assessments; however, these endpoints have barely been tapped as a valuable resource for informing ecological risk assessments and integrated monitoring. Sharon Hook, author of a critical review in the July 2014 issue of IEAM, talks to us about advantages and caveats for using biomarkers in environmental assessments.

Dr Marc S Greenberg

IEAM Podcast 15: Sedimentary, my dear Watson. Passive sampling methods and sediment remediation, with Marc Greenberg. Contaminated sediment—and how to manage them—present an ongoing problem for scientists worldwide. Management and remediation is expensive and time-consuming, often involving millions of dollars over many years. An easier solution may be coming however. The April 2014 issue of IEAM contains a special series on passive sampling methods for contaminated sediment, and Marc Greenberg provides all the details.

Ryan Hill

IEAM Podcast 14: Making the most of sparse data for wildlife risk assessments, with Ryan Hill. The wildlife risk assessment that could: overcoming sparse dose-response data. The January 2014 issue of IEAM contains a critical review describing a solution to a problem common to all wildlife risk assessments: how to work with sparse dose-response data.

Dr. Matthew Etterson

IEAM Podcast 13: Ruffling Feathers - A New Approach to Pesticide Risk Assessment for Birds, with Matthew Etterson. We talk turkey with Matthew Etterson about pesticides and bird reproduction. Etterson and colleague Rick Bennett are co-authors of two companion articles in the October 2013 issue of IEAM that present an innovative model for predicting effects of pesticides on bird reproduction.

Dr. Monique Dubé

IEAM Podcast 12: Assessing Cumulative Effects in Watersheds, with Monique Dubé.

Death by a thousand cuts—the importance of cumulative effects on watersheds.

Environment damage often results from the collective effects of multiple stressors, be they chemical, biotic, or anthropogenic. But how to capture them all for an environmental impact assessment? Enter cumulative effects assessment (CEA). Monique Dubé discusses how she and colleagues developed and applied a framework for watershed CEA in several Canadian watersheds. Access the special series “Watershed Cumulative Effects Assessment” in the July 2013 issue of IEAM.

In this episode, we hear from Glenn Suter about pragmatism—a philosophy that underlies the scientific approach. He and Susan Cormier are the authors of a commentary in the April 2013 issue of IEAM entitled “Pragmatism: A practical philosophy for environmental scientists.” Access their article in the April 2013 issue of IEAM.

Drs. Calow and Forbes

IEAM Podcast 10: For What It’s Worth: Using the Ecosystem Services Concept in ERAs, 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? Valery Forbes and Peter Calow join us to answers these questions and much more as they discuss their article “Use of the ecosystem services concept in ecological risk assessment of chemicals.” Access the series in the April 2013 issue of IEAM.
