Hard external armors have to defend against a lifetime of threats yet are traditionally understood by their ability withstand single attack. Survival bivalve mollusks thus can depend on the repair shell damage between encounters. We studied capacity for in intertidal mussel Mytilus californianus compressing live mussels 15 cycles at ∼79% predicted strength (critically fracturing 46% shells), then allowing survivors 0, 1, 2 or 4 weeks repair. Immediately after fatigue loading, shells were 20% weaker than control that had not experienced repetitive loading. However, restored full within 1 week, and greater fatiguing forces stronger those repetitively loaded lower forces. Microscopy supported hypothesis crack propagation is mechanism fatigue-caused weakening. was only partially explained, as epifluorescence microscopy calcein staining deposition showed half loading initiated direct via growth around fractures. Our findings document months faster demonstrated other mollusks. This rapid may be important mussels' success contending with predatory environmental harsh environment wave-swept rocky coasts, them address non-critical but weakening initiate plastic changes strength. highlight significant insight gained studying biological static structures but, instead, dynamic systems accumulate, respond damage.

Pismo clam extraction is currently banned in Mexico to help the recovery of natural populations. Thus, primary objective this study was gain insight on its basic biology and husbandry protocols. Growth clearance rate (CR) sand-burrowed sediment-free, laterally pressed adult clams were quantified laboratory as a function burrowing condition, flow, temperature, microalgal concentration using open-flow chambers. After 40 days, remained healthy regardless condition showed hyperbolic CR response pattern increased with directly proportional flows lower than 1000 ml min-1. Maximal asymptotic values (300 400 min-1 org-1) observed from 2000 No significant differences between burrowed clams, yet effects detected, constant maximal CRs ∼250 range 50 200 cells µl-1 decline at higher concentrations. Maintenance protocols organisms validated both weight data. To our knowledge, first providing whole-body physiological data translated into effective for clams. This approach represents fresh perspective traditional research areas, opening possibility continued experimentation under controlled conditions.

ABSTRACT Even though mollusks' capacity to repair shell damage is usually studied in response a single event, their shells have defend them against predatory and environmental threats throughout potentially multi-decadal life. We measured whether how mollusks respond chronic mechanical stress. Once week for 7 months, we compressed whole live California mussels (Mytilus californianus) 15 cycles at ∼55% of predicted one-time breaking force, treatment known cause fatigue shells. found repaired Shells experimentally stressed were just as strong the end experiment those control that had not been loaded, they more heavily patched internally. Additionally, differed morphology; heavier thicker than but increased less width, resulting flatter, domed shape. Finally, stress came cost, with having higher mortality soft tissue group. Although associated significant mussels' ability maintain ongoing may be vital survival harsh predator-filled environments.
