Spatial Portfolios in Coral Metapopulations Are Shaped by Spatiotemporal Asynchrony in Environmental Conditions Coral reefs experience spatially variable environmental conditions, shaping how populations fluctuate through time. Response diversity across species within a community (dashed box; not examined here....

Huge thanks to collaborators Kristen Davis & Peter Edmunds and to @stanforddoerr.bsky.social, and #MCRLTER + #NSF + @uslter.bsky.social network for long-term support.

Curious about portfolio effects in #marine #ecosystems? Let’s talk!

Why we care:
Spatiotemporal heterogeneity appears to be a stabilizing feature of reef systems.

Recognizing where and why coral populations respond differently helps move #conservation beyond island-scale diagnoses and toward targeted protection & restoration.

Key result:
Asynchronous pop. responses across habitats - influenced by environmental variation - provide the strongest buffering against instability.

Daily temperature variation β†’ desynchronizes populations

Thermal stress (degree heating days) β†’ synchronizes

Scale matters.

Performing Wavelet analyses with a 19-year time series of coral community structure, we asked: *How do different processes [de]synchronize coral populations across space and time?*

Coral reef decline is accelerating globally. But not all drivers act at the same scale. Some stressors shape coral dynamics over decades. Others operate at higher frequency.

Combinations of acute and chronic stressors can generate transient synchrony among coral populations.

Darwin speculated that it was energetically costly to be an hermaphrodite. He thought that might explain why they were relatively rare in animals. Our paper out today tested this conjecture for the first time.

Winning an NSF Postdoctoral Research Fellowship is a huge vote of confidence in the career of a freshly-minted researcher, and right now an entire cohort of people with distinction are apparently waiting to find out when they'll get their next paycheck as the month ends
