Marine #megafauna is at risk in many seas Sea otters are iconic predators in the north Pacific, but they were heavily hunted for their fur in the 18th and 19th centuries, as @nancyknowlton.bsky.social comments in this post #GES4SEAS #MOOC #oceanoptimism
My first paper as last author 🎉 We show how marine heatwaves and biological invasions interact to weaken top-down control in coastal ecosystems. Rising temperatures strongly reduce grazing by Paracentrotus lividus and potential control over invasive spp onlinelibrary.wiley.com/doi/10.1002/...
Marine Heatwaves and Reduced Dietary Diversity Weaken Herbivory Control Over the Invasive Seaweed Rugulopteryx okamurae
The brown macroalga Rugulopteryx okamurae, identified as invasive in the Strait of Gibraltar a decade ago, is rapidly expanding across the NE Atlantic and the NW Mediterranean, displacing native asse....

Evaluating respiration rates of #Paracentrotus lividus fed with different proportions of the invasive alga #Rugulopteryx okamurae
The sea urchin Paracentrotus seems to not like to graze on the invasive macroalga Rugulopteryx okamurae. @bernalocean.bsky.social #ITRS2025 🧪🦑
My first #ITRS! Very happy to have spent a fantistic week with colleagues and many friends full of macroalgae, sea urchins, and much more!!
This is phenomenal. Sea surface temperatures are >5C above average to the west of the UK and around Iceland. It's the strongest area of anomalous warmth on the planet at the moment. It's the warmest in recorded history for northwest Europe.
Almost there! Excited for the next #ITRS2025

Kelp forests on the coast of Maine are in decline owing to rapid ocean warming and are being replaced by turf algae, which alter the ecosystem’s chemistry, hindering the recovery of kelp forests. Learn more in this week's issue of Science: scim.ag/4dwzl8j

During our first week of sampling, we have already noticed a remarkable change in the percentage cover of macroalgae in several sites of the Cyclades Islands. Once macroalgal forests, now turf... @skatsanevakis.bsky.social @rilovlab.bsky.social @ceabcsic.bsky.social
Another experiment started! How fishes are interacting with the invasive macroalgae #Rugulopteryx okamurae?
Last week, President Trump removed key protections from a marine protected area that's home to coral reefs, whales, sea turtles, and countless fish. My op-ed for @us.theconversation.com explains why that's bad and we should not do that. theconversation.com/trump-is-str... 🧪🦑🌎🐟
Trump is stripping protections from marine protected areas – why that’s a problem for fishing’s future, and for whales, corals and other ocean life
America’s marine protected areas help fish populations thrive. Trump’s plan to open them to industrial fishing may ultimately harm the fishing industry itself.

My first PostDoc first publication! Our study shows long-term negative effects of the invasive macroalga #Rugulopteryx #okamurae on the common sea urchin #Paracentrotus #lividus. Invasion context matters! sciencedirect.com/science/arti...
My number of followers here is already higher than in the older-toxic platform. Time to full adopt Blue Sky.
“The growing threat of invasive alien species in Europe”. What are we doing to understand the invasion by #Rugulopteryx #okamurae? Thanks @euronews.com for spreading part of our work at IFAPA - Junta de Andalucía www.euronews.com/green/2024/1...

Would love to see this network evolve to be better than the bird site! please connect with me if you’re interested in any of the following: coral reef ecology, scuba diving, photogrammetry / 3d modeling, statistics/ statistical modeling, AI, robotics/automation, or academia 💙
Giant kelp forests are being restored in Tasmania. This kelp forest is one of the healthiest I’ve seen for many years.
The last chapter of my #PhD is now published in @JPhycology! We explored biotic and abiotic interactions around the initial crucial stages of development of a #marineforest former species in Madeira with implications for future restoration actions. OA link: onlinelibrary.wiley.com/doi/full/10....
Great to see so many marine scientists already on Bluesky - to help get you find some of them here is a starting list list of a few marine biologists If you want to be added (or deleted), or know other I have missed (many for sure) - just contact me and I'll sort it go.bsky.app/RS5zQHv
Physical heterogeneity or complexity is well-known to affect biodiversity, but what about ecosystem functioning? Our study (now published) shows heterogeneity drives cascades that boost foundation species, biodiversity, and multifunctionality esajournals.onlinelibrary.wiley.com/doi/epdf/10....
First post on Bluesky! This map shows some of the institutions/researchers/labs that were already using our #EnvLoggers as of June 2023. They're more than 130 institutions from 33 countries!
Changing your clocks in the next few weeks? Around a third of the world's countries will be. But, around half of the countries of the world once celebrated daylight saving time, with many abandoning it, including over the past decade. www.pewresearch.org/short-reads/...
More research showing that single-blind peer review creates biased outcomes for higher-income and English-speaking countries. If we know that double-blind peer review decreases bias, then shouldn’t it be used at all journals? #PeerReview
I should also plug the new kelp mapping guidebook put out by Luba + Hakai/TNC last week! hakai.org/kelp-mapping...
