WaterTalk: What happens when fish go on “the Pill”?

Thursday, November 28, 2019 2:30 pm - 3:30 pm EST (GMT -05:00)

As part of the Water Institute's WaterTalks lecture series Dr. Karen Kidd will present: 
What happens when fish go on “the Pill”?

More information

Natural and synthetic estrogens in municipal wastewater discharges are affecting sexual development and reproduction in fishes worldwide. It is unknown, however, if the feminization of male fishes from these releases affect population sustainability and whether there may be other indirect effects on lower-trophic-level organisms living downstream.  This talk will describe a whole ecosystem study at the Experimental Lakes Area in northwestern Ontario, and how fish and other aquatic species responded to the additions of the synthetic estrogen used in the birth control pill, 17a-ethynylestradiol. Overall, results showed that estrogens in municipal wastewater have the potential to affect aquatic food webs both directly and indirectly, of which the latter is rarely considered.  

Speaker Bio

Karen Kidd

Dr. Kidd received her BSc in Environmental Toxicology from the University of Guelph (1991) and her PhD in Biology from the University of Alberta (1996).  Dr. Kidd is an ecotoxicologist, studying how the health of aquatic organisms and food webs are affected by human activities and the fate of pollutants in freshwater ecosystems. 

Dr. Kidd joined McMaster University, Hamilton, Ontario in 2017 as the Jarislowsky Chair in Environment and Health and has a joint appointment in the Department of Biology and the School of Geography and Earth Sciences.

Prior to McMaster, Dr. Kidd lived in beautiful New Brunswick and worked in the Biology Department and the Canadian Rivers Institute at the University of New Brunswick Saint John. She was a Professor of Biology and held a Canada Research Chair in Chemical Contamination of Food Webs (Tier II 2004-2014; Tier I 2015-17). Karen also spent 6 fantastic years with Fisheries & Oceans Canada in Winnipeg, Manitoba as a Research Scientist.

Dr. Kidd’s lab's research is multidisciplinary in nature - a combination of ecology, biogeochemistry, chemistry and toxicology - and is on lakes, rivers, wetlands, and coastal zones spanning tropical through Arctic climates.

Her field and lab research is on how industrial, agricultural, aquacultural and municipal effluents affect aquatic organisms and food web structure, the types and levels of legacy and emerging contaminants in freshwaters and coastal ecosystems, and why fish and other aquatic life from some areas are higher in contaminants than others.
