Aquatic and aerial oxygen consumption of cool temperate gastropods: A comparison with some mediterranean species

Species interactions can shift the response of a maerl bed community to ocean acidification and warming

“…Assemblage exhibited a strong seasonal pattern for all metabolic parameters, which is consistent with the higher metabolism in the summer for most of the species incubated at the specific scale. This higher metabolism in the summer has already been shown in urchins (Brockington and Peck, 2001), gastropods (Davies, 1966;Innes and Houlihan, 1985;Martin et al, 2006b), and living maerl (Potin et al, 1990;Martin et al, 2006a) and is strongly related to changes in numerous environmental and biological variables, such as light intensity and photoperiod, temperature, and nutrient or food availability (Godbold and Solan, 2013;Thomsen et al, 2013).…”

A massive summer-kill of the dog-whelk, Nucella lapillus, on the north Cornwall coast in 1995: freak or forerunner?

“…Water is retained in the mantle cavity when tidally exposed to air, lessening the e¡ects of desiccation (Boyle et al, 1979) and oxygen uptake in air is consistently higher than in water up to the temperature at which heat death occurs (Sandison, 1966(Sandison, , 1967. This capacity to maintain aerobic metabolism during aerial exposure (see also Innes & Houlihan, 1985) would confer a degree of immunity from the e¡ects of hypoxia during immersion since an oxygen debt could be regularly repaid, either completely or partially, with each tidal cycle. Recovery would be facilitated by the anaerobic metabolic pathways found in marine molluscs (reviewed by GÌde & Grieshaber, 1986;de Zwaan, 1991): octopine production commonly substitutes for the formation of lactate, and the presence of high octopine dehydrogenase activity in N. lapillus (Regnouf & Thoai, 1970;Barrett & Ko« rting, 1981), which is detectable also in O. erinacea (Livingstone et al, 1983), may be signi¢cant in this context.…”

Thermal tolerance, evaporative water loss, air-water oxygen consumption and zonation of intertidal prosobranchs: a new synthesis

“…There have been few comparative studies of the aerial and aquatic gas exchange rates of intertidal gastropods species from different shore levels (Houlihan, 1979;Innes & Houlihan, 1985;McMahon & Russell-Hunter, 1977;Micallef, 1967;Sandison, 1966;Toulmond, 1967a, b). While aerial respiratory rates in intertidal gastropods depend in part on degree of pallial water retention (Holulihan et al, 1982) causing variability in aerial 02 uptake rate determinations, a recent review of respiratory compensation in intertidal molluscs, summarizing all available data for intertidal meso-and neogastropods (McMahon, 1988), yielded the somewhat surprising result that the mean ratio of aerial to aquatic 02 consumption rate in eulittoral meso-and neogastropod species was essentially 1: 1 regardless of microzonation within the eulittoral.…”
