... to permanently submerged conditions in seawater tanks. In this study, green shore crabs, Carcinus maenas , were acclimated to either a simulated tidal regime of continuous emersion–immersion (‘tidal’) or to permanently submerged conditions (‘non-tidal’) to assess their physiological responses to subsequent...

... Highlighted Article: Transcriptional, physiological, morphological and comparative genomics data reveal mechanisms recruited to resolve the dual challenges of skin providing a barrier and exchange interface during terrestrial acclimation in an amphibious fish. Ecological genomics Emersion Mangrove...

...Elliot Scanes; Laura M. Parker; Wayne A. O'Connor; Laura S. Stapp; Pauline M. Ross ABSTRACT Sessile marine molluscs living in the intertidal zone experience periods of internal acidosis when exposed to air (emersion) during low tide. Relative to other marine organisms, molluscs have been identified...

...Peter A. Fields; Chris Eurich; William L. Gao; Bekim Cela During aerial exposure (emersion), most sessile intertidal invertebrates experience cellular stress caused by hypoxia, and the amount and types of hypoxia-induced stress will differ as exposure time increases, likely leading to altered...

... enzyme activities( Frick and Wright, 2002a ),suggesting that metabolic rate is not depressed as in prolonged emersion in lungfish ( Smith, 1930 ). Graham reviewed the effects of air-exposure on oxygen uptake in air-breathing fish and concluded that the active amphibious species generally maintain oxygen...

... it can be confronted with aerial exposure during the dry season. This study aimed to examine nitrogen excretion and metabolism in this fish during 4 days of emersion. Contrary to previous reports, A. testudineus does not possess a functional hepatic ornithineurea cycle because no carbamoyl phosphate...

...Chris N. Airriess; Brian R. Mcmahon ABSTRACT Changes in cardiac function and arterial haemolymph flow associated with 6 h of emersion were investigated in the crab Cancer magister using an ultrasonic flowmeter. This species is usually found sublittorally but, owing to the large-scale horizontal...

... throughout. The mussels were observed to gape periodically when in air. Periodic gaping permitted aerial gas exchange such that mantle fluid and dissolved oxygen concentration stabilized at levels about twice and half, respectively, those of immersed mussels. During emersion, a dilute carbonate buffer...

... in crayfish before, during and after 24 h emersion. The concentrations of K + and Mg 2+ increased during aerial exposure and returned to pre-emersion levels during immersed recovery. Large increases in the level of circulating L-lactate and Ca 2+ were correlated with short- and long-term aerial exposure...
