The Asian freshwater clam, Corbicula fluminea, was emersed at 23°C under three conditions: humid air, N₂ hypoxia, or air with valves clamped or bound shut. Under all conditions, clams became acidotic during emersion. In air, hemolymph pH declined from 790 to 7.14 in 72 h. Hypoxic clams displayed a similar decline in pH, but clams with valves clamped became acidotic more rapidly. Hemolymph CO₂ content (Cco₂) and Pco₂ rose with duration of aerial exposure in all treatment groups. However… Expand
Behavioral and Physiological Responses to Emersion in Freshwater Bivalves
TLDR
Some emersion adaptations of freshwater species appear to be modifications of those displayed by intertidal and estuarine bivalves, while others appear independently evolved to allow survival of the extreme emersion periods associated with life in shallow freshwaters. Expand
Effect of Air Exposure on Acid–Base Balance of Hemolymph in Hard-shelled Mussel Mytilus coruscus
We investigated the hemolymph acid–base status of the hard-shelled mussel Mytilus coruscus exposed to air for 24–48 h at 24°C. M. coruscus exposed to air showed a decrease in hemolymph pH from 7.625Expand
Acid-base disturbances accompanying emersion in the scallop Pecten maximus (L.)
TLDR
It is suggested that the inability of P. maximus to counter the respiratory acidosis encountered during emersion is responsible for the poor survival of this species in air. Expand
Ionic and Acid-Base Consequences of Exposure to Increased Salinity in the Zebra Mussel, Dreissena polymorpha
TLDR
The responses of D. polymorpha to modest changes in salinity were largely the result of passive processes, and the Na/K ratio in hemolymph was maintained within relatively narrow bounds throughout the procedure and may contribute to the mussels’ ability to volume-regulate during an osmotic challenge. Expand
Metabolic characteristics of the Japanese clam Ruditapes philippinarum (Adams & Reeve) during aerial exposure
TLDR
Accumulation of succinate and alanine in the tissues proved that the clam shifted its metabolism to anaerobiosis and retention values of the haemolymph po2 indicated that the clams depend partially on some aerobic manner. Expand
Effect of dissolved oxygen on the acid-base balance and ion concentration of Taiwan abalone Haliotis diversicolor supertexta
TLDR
It is concluded that the stress of DO at 3.08 mg/l and lower causes disturbance in the acid–base balance as well as anaerobic metabolism of H. diversicolor supertexta, resulting in glucose and lactate productions and acidosis in a short-term period. Expand
The effects of intertidal air exposure on the respiratory physiology and the killing activity of hemocytes in the pacific oyster, Crassostrea gigas (Thunberg)
TLDR
The respiratory and immune responses of oysters exposed to air at normal seasonal temperatures, and to determine whether these stresses associated with emersion inhibit the immune system of the oyster and contribute to the summer mortalities are determined. Expand
Survival of zebra mussels (dreissena polymorpha) and asian clams (corbicula fluminea) under extreme hypoxia
TLDR
Zebra mussels and Asian clams were exposed to acute hypoxia in order to determine anoxia tolerance and assess O2 as an efficacious, nonchemical, environmentally neutral, macrofouling control strategy. Expand
Osmoregulation in Dreissena polymorpha: the Importance of Na, Cl, K, and Particularly Mg.
TLDR
Zebra mussels (Dreissena polymorpha) individuals were unable to survive beyond 5 days in deionized water and required minimal concentrations of Na, Cl, K, and Mg for prolonged storage (>51 days) under laboratory conditions. Expand
Ion transport and acid-base balance in freshwater bivalves
  • Byrne, Dietz
  • Biology, Medicine
  • The Journal of experimental biology

TLDR
Serotonin (5-hydroxytryptamine, 5-HT) stimulates Na+ and Cl- transport in both species, resulting in an increase in acid secretion and a rise in blood pH, while in a Na+-free environment, serotonin had no effect on blood acid­base state in C. texasensis. Expand

A Unique Respiratory Adaptation to Emersion in the Introduced Asian Freshwater Clam corbicula Fluminea (Müller) (Lamellibranchia: Corbiculacea)
TLDR
The Asiatic clam, Corbicula fluminea, periodically consumes oxygen across exposed mantle-edge tissues sealed together by hardened mucus, appearing to be an adaptation to prolonged emersion, allowing both maintenance of substantial levels of aerobic metabolism and minimal evaporative water loss.

Calcium utilisation during anaerobiosis induced by osmotic shock in a bivalve mollusc
TLDR
Results are reported which are part of an extensive study of osmotic and behavioural responses of Scrobicularia plana (Da Costa), a euryhaline estuarine species, to varying concentrations of seawater and demonstrate the use of calcium from the shell to buffer the products of anaerobiosis. Expand
The Effects of Aerial Exposure and Subsequent Reimmersion on Hemolymph Osmolality, Ion Composition, and Ion Flux in the Freshwater Bivalve Corbicula fluminea
Hemolymph osmolality increased twofold after 120 h aerial exposure at 95% relative humidity and 25° C and was correlated with water loss (r = 0.83). Blood sodium and chloride levels remainedExpand
Behavioral and Metabolic Responses to Emersion and Subsequent Reimmersion in the Freshwater Bivalve, Corbicula fluminea.
TLDR
The freshwater bivalve, Corbicula fluminea, displayed valve movement behaviors, such as mantle edge exposure, wider gaping "ventilatory" response, and an escape or "burrowing" response when exposed to air, and the proportion of the emersion period spent in these behaviors increased with decreasing temperature. Expand
Response to temperature and hypoxia in the oxygen consumption of the introduced asiatic freshwater clam Corbicula fluminea (Müller)
TLDR
Respiratory adaptation to high temperatures and hypoxia are not as well developed in C. ftuminea as other freshwater bivalve species, reflecting a more recent penetration of freshwater, and limiting its eventual distribution in North America. Expand
Temperature and Relative Humidity Effects on Aerial Exposure Tolerance in the Freshwater Bivalve Corbicula fluminea
TLDR
The results suggest that C.fluminea can detect rates of desic cation and make behavioral adjustments and that the behavior was inhibited by low humidity and high temperature, and body size was reciprocally related to water loss rate and on longevity at 25° and 35°C. Expand
Activity and Metabolism in the Mussel Mytilus edulis L. during Intertidal Hypoxia and Aerobic Recovery
TLDR
Variations in air-gaping behavior were associated with differences in heat dissipation during exposure to air and its partitioning into aerobic and anaerobic components in intertidally and subtidally acclimatized specimens of Mytilus edulis. Expand
