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? 🐟

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:

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.

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.

Reef fishes are diverse, & so are their diets.

What led to the diversity of diets🍴seen in fishes on reefs today? 🪸🐠

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."

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"

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.

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

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:

[Dr Peter Doll @PeterCDoll]

@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

[Dr Peter Doll @PeterCDoll]

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%)!

[Jez Roff @JezRoff]

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.

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 🪸

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?”

[Australian Institute of Marine Science @aims_gov_au]

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 👏
