The 2023 marine heatwave was devastating for Caribbean reefs; in this study, we report full mortality of over 5,000 Acropora palmata colonies across a reef scale. What is worrisome is that nearly 70% of reef crests across the Caribbean faced equal or higher levels of stress doi.org/10.1016/j.is...

Online now: Keystone coral species population collapse after unprecedented heat stress

Keystone coral species population collapse after unprecedented heat stress

Climate change threatens coral reefs globally. Birkart and Alvarez-Filip document local extirpation of a keystone coral species in Mexico following unprecedented heat stress, suggesting similar outcomes for ∼70% of the Greater Caribbean’s shallow-water reefs. This highlights the need to upscale surveys using emerging technologies to locate, protect, and propagate surviving corals.

A beautifully written story about parrotfishes and coral reefs by @lisasgardiner.bsky.social

When reporting and writing this story, I learned so much about why parrotfish are AMAZING. Thanks to @kt-cramer.bsky.social @lalvarezfilip.bsky.social @anysunreef.bsky.social and @ichnologist.bsky.social for their research and perspectives on these funny fishes!

Are parrotfish a superhero for struggling reefs? Sometimes, but not always. It depends on other reef stressors. And there are a lot of stressors. https://www.snexplores.org/article/parrotfish-algae-coral-reef-ecosystems

Parrotfish shape the future of coral reefs, one bite at a time

Could these colorful fish aid struggling coral? Yes, but not always. Parrotfish play a complex role in reefs — and sometimes may cause harm.

Nature research paper: Reduced Atlantic reef growth past 2 °C warming amplifies sea-level impacts

Reduced Atlantic reef growth past 2 °C warming amplifies sea-level impacts - Nature

An analysis of coral reefs in the tropical western Atlantic suggests that nearly all will be eroding by 2100 if global warming exceeds 2 °C, which will worsen the effects of sea-level rise.

Over 70% of coral reefs in the tropical western Atlantic Ocean are projected to be in a state of erosion by 2040, increasing to nearly all reefs in 2100 if warming exceeds 2 °C above preindustrial levels, a study in Nature suggests. go.nature.com/48m9Y8F 🌊 🧪

This is figure 2, which shows reef accretion potential across western Atlantic reefs.

Parrotfish support healthy coral reefs, but they’re not a cure-all, and sometimes cause harm

A widely held view in ocean conservation asserts that parrotfish are key to healthy coral reefs. But evidence suggests that the relationship is more complicated.

The global marine heatwaves of 2023 were unprecedented in their intensity, persistence, and scale, according to a new Science study.

The findings provide insights into the region-specific drivers of these events, linking them to broader changes in the planet’s climate system. scim.ag/4lOzfwm

Across warming seas, record-breaking marine heatwaves in 2023 underscored the growing vulnerability of ecosystems and human livelihoods. These events contributed to fishery losses and revealed region-specific drivers, including enhanced shortwave radiation, oceanic advection, and changes in upper-ocean stratification. Together, these mechanisms illustrate the intensifying influence of climate variability on ocean heat extremes.

Heard of "Darwin's paradox"? It refers to Charles Darwin's observation that coral reefs are wildly productive despite occurring in nutrient-poor tropical oceans. Reefs are, so the story goes, oases in marine deserts 🏝️...

Turns out that 2/3 of these assertions are very wrong...

In all of them, we found that strategically conducting restoration activities near or bordering existing patches of the target species can enhance the structural connectivity of the landscape, while also increasing the potential for fertilization between the wild population and outplanted specimens.

Lorenzo Alvarez-Filip @lalvarezfilip.bsky.social · May 14

Our models show that considering the spatial distribution of the focal species is crucial in restoration activities. We tested our models under three different reef scenarios (degraded, healthy, and randomly distributed).

Lorenzo Alvarez-Filip @lalvarezfilip.bsky.social · May 14

Specifically, we propose a framework that integrates image analysis of commercial drone data and spatial modelling based on landscape ecology theory to identify restoration sites that structurally connect patches of a key reef-building coral across ecologically meaningful scales.

Lorenzo Alvarez-Filip @lalvarezfilip.bsky.social · May 14

Coral restoration is a rapidly growing field; however, the scalability of interventions is often a limitation to reverse coral losses at meaningful scales. We address this issue by proposing a spatially explicit approximation to optimize the outplanting design at the reefscape scale bit.ly/4kiVxoH

The hurricane impacts we report in this study occurred in 2020. Many may wonder whether Limones Reef withstood the 2023 bleaching event. The good news is that, unlike many other shallow reefs in the Caribbean, this reef still has a healthy population of A. palmata (although it underwent losses).

Lorenzo Alvarez-Filip @lalvarezfilip.bsky.social · Apr 14

One of our key findings relates to the role of phenotypic plasticity. Colonies in the most exposed environments (reef crest) developed morphological attributes that made them, and their patches, more prone to resisting the increased energy levels during hurricanes.
