Abstract
Elevated concentrations of carbon dioxide (CO2) and the acidification of
Earth's oceans are due largely to absorption by seawater of excess,
atmospheric CO2 from fossil-fuel combustion. Evidence available about CO2
effects on fish suggests that effects differ across species and perhaps
populations, and may interact with other stressors. Further, these
differences may also be associated with life-history strategies, habitat
use, and parental exposure.This webinar will summarize experimental work
from the NOAA Howard Laboratory on the effects of high CO2 on two species
of flatfish from the Northwest Atlantic, winter flounder,
Pseudopleuronectes americanus, and summer flounder, Paralichthys dentatus,
that differ in life history and habitat. Overall, winter flounder displayed
increased fertilization success and embryonic survival with increasing CO2
and decreasing temperature. The responses of winter flounder varied with
the source of adults (Mid-Atlantic Bight vs Gulf of Maine) with offspring
of Gulf of Maine origin more tolerant to elevated CO2 than those from the
Mid-Atlantic Bight, but less tolerant to warmer water. Summer flounder
exhibited reduced fertilization and embryonic survival with elevated CO2
and colder temperature. Population and species differences in early
life-stage responses to elevated CO2 may influence the adaptation potential
and persistence of these species at predicted levels of near-future climate
change.


Brief Biography
Chris Chambers is a Fisheries Ecologist at the NOAA Fisheries' Howard
Marine Sciences Laboratory in Sandy Hook, New Jersey, where he leads the
Life History and Recruitment group. He received his Ph.D. from Duke
University (Zoology) where he worked on ecological interactions in two
different temporary freshwater habitats (pond-breeding amphibians and
treehole-breeding mosquitoes). His research on marine fisheries began with
a post-doctoral position at McGill University where he spent summers in
Newfoundland working with capelin, flounder, and cod, and continued while
on staff at the Huntsman Marine Science Centre where he conducted modeling
studies with colleagues at the Oak Ridge National Laboratory. Since joining
NOAA in 1996, Chris has primarily used experimental approaches to
investigate questions about the role of the environment and parentage in
production, recruitment, and population dynamics of marine fishes important
to the mid-Atlantic and New England regions of the USA. He is involved in
multiple projects ranging from ecology to toxicology to modeling, and is
currently the PI on a multi-year study on biological responses of finfish
to ocean acidification funded by NOAA's Ocean Acidification Program. He has
a strong commitment to education and outreach activities, and has served as
a mentor to over 100 graduate, undergraduate, and high school students.
