Abstract: Nanosilver (AgNP) is a ubiquitous antibacterial compound used in many commercial products, and as such is becoming more commonly found in the environment with high potential for non-point source release. At the International Institute for Sustainable Development (IISD) Experimental Lakes Area (ELA), we conducted a large collaborative study to evaluate the impacts of AgNP on a whole lake. Yellow perch populations demonstrated clear oxidative stress responses at the cellular level, reductions in consumption and activity at the individual level, and reduced densities and gross consumption at the population level. Similarly, Northern Pike populations demonstrated reduced growth rates and reductions in consumption and activity at the individual level and reduced gross consumption at the population level. Stable isotope analysis indicates that both perch and pike shifted towards more pelagic resources during and after AgNP additions, which we speculate is a result of settling AgNP reducing benthic productivity. This combination of both direct and indirect responses of fishes to this emerging contaminant indicates the potential risks of AgNP release into waterways at environmentally relevant concentrations.

 

Biography: Dr. Michael Rennie is an Associate Professor and has held a Canada Research Chair in Freshwater Ecology and Fisheries since joining Lakehead University in 2015. He is also a Research Fellow with the International Institute for Sustainable Development (IISD) Experimental Lakes Area (ELA) where he has led the fish populations program since 2010. Since 2018, he has been the director of the Aquatic Toxicology Research Centre at Lakehead University. His research at the ELA and in the Great Lakes is largely focused on how human disturbance and novel contaminants alter food web structure and function (e.g., rates and pathways of energy flow through foodwebs).

Physiology, behaviour, and conservation of the endangered redside dace

Presented by Dr. Andy Turko

Eastburn Postdoctoral Fellow, McMaster University

Abstract: Freshwater streams and rivers are one of the most threatened habitat types globally due to the combined effects of climate change and local-scale land use changes. Changes in the thermal conditions of these habitats are especially problematic for many fishes, and my research indicates that high temperatures may be responsible for the declines of some endangered species such as the redside dace Clinostomus elongatus. First, I will discuss field studies of upper thermal tolerance and how this is influenced by ontogeny and nutrition. Next, I will demonstrate how we are using thermal tolerance data to inform future reintroduction programs. Finally, I will discuss my ongoing work that integrates behavioural temperature preferences with physiological performance to understand optimal habitat conditions for this species. Overall, my work improves our fundamental understanding of the links between habitat choice and organismal performance and indicates that thermal biology should be incorporated into ongoing conservation programs.

 

Biography: Andy Turko is a postdoctoral fellow at McMaster University, where he works with Drs. Graham Scott (Dept of Biology) and Sigal Balshine (Dept of Psychology, Neuroscience, and Behaviour). He was previously a postdoc at the Great Lakes Institute for Environmental Research at the University of Windsor and completed his Ph.D. at the University of Guelph. His research integrates physiology and behaviour to understand how fishes cope with changing environmental conditions.

Virtual Diversity in Science Event – February 9, 2022
Feb 9 @ 6:30 pm – 9:00 pm

Dear L-SETAC community:

We are nearly two years into the COVID-19 pandemic, and as we are all still trying to find our way through, L-SETAC Diversity in Science Committee (DISC) invites you to highlight the International Day of Women and Girls in Science to discuss:

    • Where are we now?
    • How Does a Pandemic Change our Actions Towards Achieving Equity in Science?

Join us on Wednesday, February 9, from 6:30-9 pm, for a virtual mingling of minds. We hope this will give us the opportunity to share on the highs and lows of our respective pandemic, give each other support, and find creative ways on how to support each other in times of need.

When:  Wednesday, February 9th, 2022 from 6:30 – 9 PM
RSVP:  Please complete the RSVP form to receive the Zoom meeting link (check your junk folder or email the event contact if you don’t receive it).
Cost:  Free (donations will be collected towards a charity selected by the DISC)

International Women’s Day Event – This Changes Everything: movie discussion
Mar 8 @ 6:30 am – 8:30 am

Join us on Tuesday March 8, from 6:30 pm to 8:30 pm, to discuss the movie This Changes Everything. This eye-opening documentary describes and synthesizes data on the historical and ongoing gender disparity in Hollywood, including the impact it has on young girls not seeing role models that look like them. Many well-known actresses, directors, and executives account their experiences navigating the media entertainment industry with the underrepresentation and misrepresentation of women.

Trailer for the documentary: This Changes Everything (2019) Official Trailer HD, Fathom Event Documentary Movie
