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. 😔

Pleased to share our new #GiantClam research out now in @Ecol_Evol! Genetic analysis shows small giant clams (Tridacna maxima) in the Coral Sea & Cook Islands have high haplotype diversities but different population structures. 📝: doi.org/10.1002/ece3.7… 📸: @PeterCDoll

Some great work by @ChandlerJosie and team. 4k video workflows to image 40+ conlonies per dive and predict 3D surface area from rapid 1D field measures for a wide range of corals! @CoralReefEcoLab @burn_deborah @PeterCDoll Agus Piccaluga Abby Johnades. rdcu.be/dS0NY

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%)!

Great work by ⁦@nature_org⁩ & ⁦@IMASUTAS⁩, spearheaded by our valued collaborator ⁦@ScottDLing⁩! youtu.be/SfmP0aP1hNQ?si…

Excited to announce a new paper from our group: Detailed feeding rates of different crown of thorns seastar (Acanthaster) larvae measured using flow cytometry by Frances Patel @SeaSim_AIMS @aims_gov_au link.springer.com/article/10.100…

The final chapter of my PhD is out! We explored the patterns of coral bleaching, revealing how small-scale hydrodynamics and colony size shape resilience in individual coral colonies 🪸 Find the paper in Mar Env Res #OpenAccess researchgate.net/publication/37… @ReefFunctionHub

Exciting new crown-of-thorns starfish research led by @ChandlerJosie out now, featuring a novel sampling method, a renewed population irruption in the northern GBR & much more! Link to OA paper: rdcu.be/dqCHi @burn_deborah @PeterCDoll @SarahKwong4 @bethan_blue @KaiPacey

Alongside spawning #coral @SeaSim_AIMS, we also spawn #CrownOfThornsStarfish! Each year the team raise >5 million larvae for their research. 📺 @klesita shows us how they check if the starfish are ♂️ or ♀️ and explains their research to answer “how old are you?”

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 👏
