Adriatic Clam Populations: Tracking Life History Under Changing Conditions
Seventeen thousand nine hundred seven clams measured, nearly 1,500 sexed, and a growth curve that holds across three fishing districts: this is the kind of empirical foundation that turns a fishery from guesswork into governance. The Adriatic's *Callista chione* is slow to mature and slower to age, yet it reaches commercial size years before reproduction even peaks. That mismatch matters.
Shell Formation Under Threat: Environmental Stressors and Molluscan Resilience
Shell formation is not a passive process; it is a precisely calibrated biological cascade, and new research shows just how vulnerable that cascade is. A mechanistic review in our latest report synthesizes how climate drivers, seawater chemistry shifts, and contaminants disrupt biomineralization across molluscan life stages. The proposed hierarchical framework links molecular disturbances to structural defects in calcium carbonate, offering a testable path forward. It is rigorous, evidence-driven, and exactly the kind of integrated synthesis conservation work needs.
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.
