The Big Question Remains

Road Map

Thinking about OA & Evolution:

what do we know?

Thinking about OA & Evolution:

what do we know?

Adaptation in OA research:

what do we need to know?

OA Community headed that way:Breeding experiments on marine invertebrates

A second approach: Experimental evolution in the lab

Acclimation & Physiology

2. Persistent carry-over effects in early stages

3. Adult condition can change the story

Introducing the OMEGAS

We framed the question:

1. Physiological differences amongst intertidal mussel

populations

2. Evidence for cross-site differences & heritable body size in

purple urchin larvae

Breeding experiment:Cross Design

Larval culture

Sensitivity to elevated pCO2 varies among and within families

OMEGAS thus far…

The Future for the CCLME?

Challenges remain!

Exploration of gradients over ecologically-relevant space

Calcification

Larvae raised under elevated CO2 are smaller
