Fiddler Crabs' Adaptive Strategies Reveal Resilience to Warming Mangrove Habitats
For over sixty years, the mangrove fiddler crab *Paraleptuca chlorophthalmus* has been recognized as a sentinel of ecosystem health, yet its full thermal response remained unmeasured. Our new research closes that gap. We find that while the crab's metabolism peaks near 33°C and falters beyond 42°C, its locomotor activity remains stable across a far wider range, 22 to 38°C. This behavioral buffer suggests the species is thermally equipped to persist under projected warming.
Warming Waters Disrupt Caribbean King Crab Larvae Behavior
Caribbean king crab larvae swim less and die more at 32°C, a near threefold jump in mortality over the control group. The shift is quiet but consequential: first-stage larvae reverse their vertical swimming, sinking faster rather than rising. That behavioral flip threatens dispersal and larval supply for outplanted populations. For restoration programs, this is a warning that stocking reefs with *Maguimithrax spinosissimus* assumes a resilience the larvae may not have.
Warming's Metabolic Stress Outweighs Acidification's Impact on Larval Survival
Larval survival in the dog conch falters most under extreme warming, not acidification alone. Our study shows that temperature, pH, and their interaction significantly reduce survival, with thermal stress overriding pH-dependent differences at 34 °C. Growth responds to pH, yet metabolism peaks under heat, revealing a physiological trade-off. These findings underscore that warming may become the dominant constraint on tropical marine larvae, reinforcing why integrated climate indicators, like those tracked in our 2025 Temperature Anomalies, matter for predicting coastal ecosystem vulnerability.
