“…The answer to one of the questions put in the introduction is that the three species of marine gastropods examined do not produce significant amounts of lactate, thus behaving more like other marine molluscs (Hammen, 1975;de Zwaan, 1977) than like terrestrial (Meenakshi, 1958;Wieser, 1978) or fresh water (Brand, Baerenstein & Mehlmann, 1950) gastropods.…”

“…An additional complication suggested by my data is that in the sublittoral species N. reticulatus anoxia does not lead to accumulation of succinate whereas the concentration of alanine reaches fairly high values. In this species -which is never in danger of desiccation -the sole function of the alanine pathways may be in connexion with maintaining redox balance under anoxia, comparable to the formation of lactate in the pulmonate snail Helix pomatia (Wieser, 1978).…”

“…(2) Do marine gastropods accumulate lactate -as do their terrestrial relatives Meenakshi, 1958;Wieser, 1978) -or are they rather to be compared to marine bivalves which, during the first phase of anaerobic metabolism, produce alanine (de Zwaan, 1977) ?…”

One commonly held opinion about the metabolism of intertidal gastropods has recently been expressed by Newell (1970) who stated that in moist air these - as well as other intertidal - animals will respire air ‘whereas under conditions of desiccation closure of… the operculum… may result in anaerobic respiration occurring with the production of lactic acid’ (pp. 266–267). However, although anaerobiosis certainly does occur in intertidal gastropods (Patané, 1957; McMahon & Russell-Hunter, 1978) the conditions controlling this type of metabolism are far from clear. Moreover, recent studies (summarized by de Zwaan, 1977) have revealed a complex pattern of anaerobic metabolism in invertebrates in which the production of lactate is only one - and certainly not the most important - element.

“…Usually, aestivating snails do not show increased LDH activity since they completely oxidize carbohydrate (Brooks & Storey, 1997a,b;Churchill & Storey, 1989). However, there is growing evidence demonstrating the importance of anaerobic pathways in energy production during aestivation (Wieser, 1978;Wieser & Wright, 1978, 1979Michaelidis, Rofalikou & Grieshaber, 1999). Anaerobic metabolism seems to occur in dormant pulmonates because the rate of oxygen consumption falls below measurable limits for hours or even days (Schmidt-Nielse, Taylor & Shkolnik, 1971).…”

Land snails usually exhibit cycles of activity and dormancy (aestivation or hibernation). The transition between these two states is accompanied by a range of behavioural and physiological responses to ensure their survival under adverse environmental conditions. Furthermore, aestivation plays an important role in shaping species' distribution patterns. We examined the seasonal patterns in biochemical tissue composition in relation to aspects of behavioural ecology in three land snail populations: one mainland and one insular population of the widespread Helix aspersa and a population (sympatric with the latter) of Helix figulina, a congeneric species with a narrow and declining distribution. Helix figulina aestivates in underground borrows, while H. aspersa spends the summer under stones and may interrupt aestivation when conditions become favourable. Prior to aestivation H. figulina accumulates metabolic fuels, which it consumes later during summer, and at the same time loses substantial body water and increases lactate dehydrogenase (LDH) activity. The insular H. aspersa population follows a similar pattern (regarding metabolites and LDH activity), with the difference that water loss is limited. However, the mainland population of H. aspersa deviates from this model with energy metabolites and water levels showing little variation throughout the year, while LDH activity is reduced. These differences probably reflect the particular behavioural and physiological patterns adopted by each species. The specialist and range-restricted H. figulina shows a constant and more predictable seasonal pattern, which may be effective for surviving in its historical biogeographic range, but it seems to be more vulnerable to possibly changing environmental conditions. On the other hand the generalist and cosmopolitan H. aspersa adopts a more flexible pattern that compensates for the effects of adverse conditions during aestivation and permits a more effective exploitation of energy resources.
