CC&E Spring 2017 Seminar Series – “Toxic Phytoplankton in a Changing Climate”

 CC&E Spring 2017 Seminar Series – “Toxic phytoplankton in a changing climate”

This Friday, February 10, 2017 the College of the Coast & Environment will be hosting Dr. Reagan Errera, from Renewable Natural Resources, LSU. Dr. Errera’s topic for the seminar will be “Toxic phytoplankton in a changing climate.” Please join us in the Dalton J. Woods Auditorium for this very informative talk.

Abstract:

Toxic phytoplankton in a changing climate
Dr. Reagan Errera, Louisiana State University

Global climate change is multi-faceted with impacts to seawater carbonate chemistry and temperature. Both of which can influence phytoplankton dynamics by limiting or augmenting certain species ability to fix carbon or change the availability and uptake of common estuarine containments leading to an increase in toxins within food webs. As harmful algal blooms (HABs) increase worldwide, a better understanding of how climate change will influence HAB abundance and duration, is needed. I will present data on the potential impact of ocean acidification and increased temperature on growth and toxin production of the major harmful algal bloom species in the
Gulf of Mexico, Karenia brevis. In addition, I will outline findings from a pilot study indicating the potential of accumulation of organic containments caused by changes in seawater carbonate chemistry. Our findings suggest that ocean acidification can lead to an increase in toxic phytoplankton, potentially impacting coastal food webs.

Lunch will be provided immediately following the seminar in the conference room next to the auditorium.

Time: 11:30 a.m. – 12:15 p.m.
