Abstract: Primarily from burning
fossil fuels\, humans are adding increasing amounts of the greenhouse gas
carbon dioxide to the atmosphere. More than a third of this new carbon dio
xide ends up in the ocean\, and more than 90% of the additional heat from
the greenhouse effect is entering the oceans. As a result the oceans are b
ecoming warmer and more stratified\, which reduces the mixing of nutrients
from below up into the surface ocean and of oxygen from the surface layer
down into the subsurface ocean. In addition the extra carbon dioxide is c
ausing the oceans to become more acidic. Can we predict how whole
mari
ne ecosystems will adapt\, when we do not yet know how much capacity indiv
idual species have to adapt to these expected changes to their environment
. I will outline a modelling framework to explore the capacity of species
to adapt to a changing environment based on existing '\;phenotypic'\
; diversity and potential '\;plasticity'\;.
