When thinking of the 'model' planktivore on reefs, fusiliers come to mind – their fusiform bodies and large eyes seem built for the job. But are these traits common among most plankton-feeding reef fishes? 🐟 🔗 The story is more nuanced than we thought: doi.org/10.1007/s11160…

Hi all, the final paper of our 6 year multi-generational experiment on climate acclimation of coral reef sea urchins is out in Marine Biology: rdcu.be/d2Ik3 Unfortunately, it looks unlikely for this species to survive anthropogenic climate change. 😔

Reef fishes are diverse, & so are their diets. What led to the diversity of diets🍴seen in fishes on reefs today? 🪸🐠 Read more here: doi.org/10.1098/rspb.2… Published in @RSocPublishing w/ @bellwoodlab, @JanStrugnell, @ParraviciniVale, & @SiqueiraAleC @jcu @ReefFunctionHub

New comment in @NatureClimate. "This is not a call for inaction. We must act - with haste. But popular urgency should not prioritize technological and scientific feasibility over climate action and evidence-driven care for social-ecological systems." doi.org/10.1038/s41558…

Finally out!!! New paper from my lab detecting the 5th crown-of-thorns seastar outbreak on the GBR with eDNA: eDNA monitoring detects new outbreak wave of corallivorous seastar (Acanthaster cf. solaris) at Lizard Island, Great Barrier Reef" rdcu.be/dJaRU

A nitrogen-fixing organelle, or “nitroplast,” has been identified in a marine alga. This discovery sheds light on the evolutionary transition from endosymbiont to organelle. Learn more this week in Science: scim.ag/6yX

The 2024 mass coral bleaching event on the Great Barrier Reef in numbers (preliminary analysis): - 46% of reefs experienced record high DHW - new record of 17.7 DHW from the southern GBR - 37% of the GBR has been exposed to three or more >6DHW events in the past decade (1/n)

Super cool coral alert 👀 Stephanocyathus (Acinocyathus) spiniger from 384m in Perth Canyon. Look at those long 'legs' - they are actually elongated costal spines that help anchor it in the substrate whilst preventing it from being buried.

Hi, Bert here! (@robert_p_streit) After 4 years in the FunHub as Comms Manager & PostDoc, I'm moving on. Thanks for the fun, follows, likes & celebration of science on social media! My new job will be far less fishy, so I'll leave with this: (from ABC Top5 in '22 @ABCaustralia)

@JezRoff @CoralReefEcoLab indeed, we have, but already on our way north again. High recent mortality in the Capricorn group (& ongoing), much less in the central GBR sectors, fortunately. Sad to hear about Eyrie (was already looking quite bleachy in Feb); wonder how North Direction and LIZ North Reef went

@PeterCDoll @CoralReefEcoLab We’ve switched latitudes Peter 😉 How’s the mortality looking? It’s low at Lizard at the moment (10-15%) but far more severe at Eyrie (50%+ and ongoing)

meanwhile in the southern GBR.. mass coral bleaching (& recent mortality) at all reefs & sites surveyed this weekend, affecting vast majority of genera & all size classes; unfortunately, slope (~8m) almost as severely affected (~80% of colonies across sites) as the crest (>90%)!

More underwater images of the mass bleaching unfolding in the northern GBR. Water temperatures appear to be dropping after prolonged heating of >5 DHW, but the coral bleaching at this reef is severe (>80% colonies), with exceptionally high rates of mortality in juvenile corals.

AIMS at JCU students dived into scicomms at their annual seminar day. The #PhD candidates showcased their cutting-edge research on #marinescience in a series of seminar + poster presentations, and speed talks. Congratulations to all speakers and winners 👏
