Light limitation and water velocity modify the impacts of simulated marine heatwaves on juvenile giant kelp Coastal regions are complex habitats, where multiple natural and anthropogenic drivers can interact to affect the survival and growth of marine organisms. The giant kelp Macrocystis pyrifera is sensi...

Our new paper in Journal of Phycology has come out today. Low light and low water motion can exacerbate the effects of marine heatwaves on giant kelp:

If anyone is looking for regular updates on my group’s research or news, we are more frequently posting things on instagram. It’s not a perfect platform, but hey. Chrisecornwall is my handle, with my lab group updates and student work posted on coastal_eco_physio_group

See you all at the next #ITRS in #Tauranga, New Zealand 🇳🇿. Hosted by Chris Battersall, Chris Cornwall & Dave Schiel. Can’t wait to see you all there! @chrisecornwall.bsky.social @benthicecol.bsky.social @nessocon.bsky.social @katynicastro.bsky.social @pippajmoore.bsky.social @marclim-uk.bsky.social

Looking forward to it, see you all soon in Tauranga Aotearoa New Zealand 2028!!

Same here, loved catching up with friends! Now on to ITRS 2028 in Tauranga!

Thanks Trine, good to hear you liked the workshop!

Thanks for arranging this #ITRS2025 workshop 🤩 It was a very useful exercise, and I loved going through all the steps of planning our perfect will-never-ever-get-funded project 😂 and to make our priorities when reality (i.e. huge funding cuts) were thrown at us 😂

Check out some snaps from our recent MEDDLE workshop at #ITRS Brest, France on experimental design. Great participants! @scor-cobs.bsky.social

Can tropical corals find refuge at higher latitudes under future warming? In our new paper in Science Advances, we argue that coral range expansion will be *far too slow* for most coral species to outpace climate change. 🪸🌊

A short 🧵 (1/16)

Anthropogenic climate change will likely outpace coral range expansion Coral reef range expansion takes centuries, and higher-latitude seas are therefore ineffective refugia for most tropical corals.

Ocean Ecosystems is calling for submissions to our collection on Ocean Ecosystem Services and Sustainable Development Goals, aiming to enhance our understanding of how to protect ocean health while ensuring the well-being of future generations www.biomedcentral.com/collections/...

Check out @ashtyn-isaak.bsky.social and her experiment at @seasim-aims.bsky.social along with other PhD student @hollykoch20.bsky.social ! Such an exciting collaboration and experiment! It explores how light and temperature related bleaching differs from the effects of ocean acidification

We just returned from a successful trip to Vancouver Island, exploring dissolved inorganic carbon use of seaweeds there. We collected more than 200 samples from over 40 species! Big help from the three students on the team (Denisa Berbece, Alessandra Walsh and Eloise Bennett)

Reminiscing on the fantastic conference put on by @aslo.org at the Aquatic Sciences Meeting in March 2025 in Charlotte, North Carolina

I presented some of my results from two natural analogue sites; Semi-enclosed lagoon and a CO2 vent

How do coralline algae survive in extreme environments?

3. Blocking in time, by Steeve Comeau and @chrisecornwall.bsky.social

Learn how to estimate the effects of two drivers on a response when your experiment is ‘blocked’ i.e. experimental units grouped in time, often because it’s not feasible to do all at once.

2. Analysing scenarios, by Steeve Comeau and @chrisecornwall.bsky.social

Learn how to estimate the effects of two drivers on a response when your experimental treatments are designed to reflect future climate scenarios.
