“…The point at which oxygen consumption ceases to be oxygen-independent and becomes oxygen-dependent is known as critical oxygen tension P,; this varies between species or individuals with temperature and/or salinity (e, g. Bayne, 1971;Newel1 et al, 1977;Hawkins and Ultsch, 1979;Shumway, 1981;Shumway and Marsden, 1982), body size (e. g. Bayne, 1971Bayne, , 1973Taylor and Brand, 1975b;Shumway, 1981), ventilation rate (Bayne, 197 1, 1973), likelihood of experiencing hypoxia (Bayne, 1973;Murdoch and Shumway, 1980) and 'degree of openness' (Famme, 1980). With the exception of Taylor and Brand (1975a, b), Bayne (1971Bayne ( , 1973 and Famme (1980) all of the above studies were carried out with gastropods.…”

Acclimated and acute rates of oxygen consumption of the American oyster Crassostrea virginica (Gmelin) were measured under 9 salinity-temperature combinations during declining oxygen tensions. In acclimated and non-acclimated individuals the basal rate of oxygen uptake increased significantly with each 10 C" rise in temperature. Multiple regression equations relating exposure and experimental temperatures and salinities to VO, indicated: (1) as acclimation salinity decreased, the effect of exposure temperature became more pronounced; (2) as acclimation salinity decreased, the effect of exposure salinity decreased; (3) as acclimation temperature increased, the effect of exposure salinity decreased; (4) as acclimation temperature increased, the effect of exposure temperature increased. There is little or no evidence for temperature acclimation even after 3 wk. Q,, values for warm acclimated oysters were generally higher than those of cold adapted oysters with the exception of individuals acclimated at a salinity of 7 %o S and exposed to 28 %O S. At any experimental salinity the highest Q,,, values were observed between 20 and 30°C. C. virginica is well able to regulate VO, when exposed to declining oxygen tensions at all temperature-salinity combinations tested; this capacity decreased considerably at all test temperatures in oysters acclimated tq 7 % S. There is no clear pattern of response between exposure conditions and ability to regulate VO,; the degree of regulation decreases with increasing temperature and/or decreasing salinity. The results indicate that the respiratory physiology of C. virginica is highly adapted to life in a fluctuating environment.

“…The method used to measure oxygen uptake in water confined the animals in a closed system for 6 h which would have reduced the oxygen tension of the water. However, Murdoch & Shumway (1980) found the oxygen uptake rate of Chiton pelliserpentis to be independent of oxygen tension down to a level of 30% of oxygen saturation, and as the minimum level of oxygen saturation in this study dropped to only 60% it is unlikely that any chitons became hypoxic.…”

“…Although the study by Murdoch & Shumway (1980) of chitons from the Otago Harbour, New Zealand, indicated that the ratio of aquatic to aerial respiration values for each species was dependent on percentage exposure, other studies of chitons do not wholly support this hypothesis. Kincannon (1975) found no significant difference between aquatic oxygen uptake of subtidal and intertidal Tonicella lineata.…”

“…Many of these studies, and similar work dealing with chitons (Murdoch & Shumway 1980), indicated that ratios of aquatic to aerial oxygen consumption were dependent on the percentage of aerial exposure experienced; high-shore animals are often better able to respire in air than water. Exceptions to this trend (e.g., McMahon & Russell-Hunter 1977) may Received 19 July 1984;accepted 6 September 1984 *Present address: Fisheries Management Division, Min-istry of Agriculture and Fisheries, Private Bag, New Plymouth, New Zealand be because of a lack of appreciation of the importance of mantle cavity fluid and activity levels in respiration experiments (Houlihan & Innes 1982), although Branch & Newell (1978) found that the pattern of respiration in 3 limpet species was related to energy requirements and food availability.…”

Respiration in air and water of the chitonChiton pelliserpentisfrom high and low zones of a sheltered shore

Oxygen uptake of Chiton pelliserpentis from high and low zones of a sheltered shore was measured in air and water at various temperatures. Oxygen uptake in water was higher than aerial oxygen uptake for both chiton groups. Oxygen consumption by low-shore chitons was more dependent on temperature than that by high-shore chitons. On the low shore, small chitons were affected more by changes in temperature than were large animals, whereas on the high shore all sizes of chitons were influenced to the same extent. Intershore differences in respiration trends are best explained as adaptations by high-shore chitons to conserve energy, rather than being dependent on shore level.

Oxygen uptake (V 02) and haemolymph oxygen tension (p 02) were determined for the intertidal, stalked barnacle Calantica spinosa (Quoy & Gaimardl during submersion and aerial exposure at I SOc. V 02 did not change significantly with emersion, but peduncular sinus haemolymph P 02 increased significantly after 1-2 h in air. The maintenance of aerobic metabolism during aerial exposure descqbed for C. spinosa contrasts with the depressed V 02 generally reported for intertidal filter-feeding invertebrates on emersion. The increased haemolymph P 02 reported for stalked barnacles in air (characteristic of terrestrial, airbreathing decapod crustaceans) is in contrast to the respiratory pattern displayed by other aquatic invertebrates during aerial exposure. The respiratory physiology of C. spinosa in aquatic and aerial environments is discussed with particular reference to its feeding behaviour.
