“…Resting oxygen consumption decreases with enzyme heterozygosity in the American oyster Crassostrea virginica (Koehn and Shumway 1982), the gastropod Thais hemostomata (Garton 1984), the coot clam Mulinia lateralis , the rainbow trout Salmo gairdneiri (Danzmann et al 1987, Danzmann 1988, the blue mussel M. edulis (Diehl et al 1985(Diehl et al , 1986 and the tiger salamander A. tigrinum (Mitton et al 1986). These reports are sufficiently numerous, and the taxa are so diverse that they lead me to assert that the relationship is general for poikilotherms.…”

“…This association between homozygosity and maintenance metabolism agrees with previous studies (see review in Hawkins & Bayne 1992). Mussels with higher mair~ierlarlce requixenlents should have less energy available for other energetic processes (Diehl et al 1986, Hawkins et al 1986, Koehn & Bayne 1989, Hawkins & Bayne 1992) and thus be more vulnerable to adverse conditions. This corroborates Peterson's (1980) report that susceptible stocks of mussels have higher maintenance metabolism than more resistant stocks.…”

We examined the relationship of summer mortality to reproductive events for suspensioncultured mussels h/lytilus edulis L, in the Magdalen Islands. Parameters associated with gametogenesis and spawning were followed along w t h the tuning and intensity of mortality from mid-June to midSeptember 1991. For mussels maintained In a shallow lagoon (the usual mussel culture s~t e ) , summer mortality began in late July as a major spawning event was e n d~n g and as summer temperatures peaked (>20°C). Mussels from this group showed low energetic contents after spawning and during the period of highest mortality, glycogen content decreased rapidly and shell growth ceased. Thus, mussels weakened by a major spawning were at the same time submitted to stressful temperatures. Summer mortalities were observed until the end of the experimental period (mid-September) even though surviving mussels seemed to have improved their condition in late August (when glycogen content, tissue mass and shell length had increased). By mid-September approximately 65 % of the mussels had been lost. In contrast, no summer mortality was observed for mussels from the same stock that were maintained at 16 m depth in the open sea. These mussels were exposed to lower temperatures and spawned less extensively than those in the lagoon. They had no major spawning in late July and were never completely empty of gametes. Our results suggest that suspension-cultured mussels in Magdalen Islands lagoons pay a high reproductive cost in terms of survival when a major spawning is completed during a period of stressful environmental conditions, such as high water temperatures.

“…In other studies (e.g. Rodhouse & Gaffney, 1984;Diehl et al, 1986), a single stressful treatment has been applied a priori to a set of experimental organisms to amplify MLH-fitness relationships (but see Houle, 1989). Finally, MLH-fitness relationships have been compared in organisms subjected to stressml vs. nonstressful conditions of various types.…”

The effects of environmental quantity (moderate soil moisture vs. low soil moisture) and quality (low soil moisture vs. low temperature) on multilocus heterozygosity (MLH)-growth relationships were tested in the earthworm Eisenia fetida. The control treatment was high soil moisture and high temperature. Fresh weight was measured weekly for 4 weeks; MLH was computed for eight polymorphic loci. Moderate moisture limited growth (change in fresh weight) to 50 per cent of control growth; both low moisture and low temperature limited growth to 25 per cent of control growth. MLH was not correlated with growth at any time in the control treatment. MLH was strongly correlated with growth (P < 0.01) in three out of four weekly intervals in the moderate moisture treatment; MLH was weakly correlated with growth (P < 0.05) in two out of four weekly intervals in the low moisture treatment. MLH was not correlated with growth at any time in the low temperature treatment. Moderate soil moisture produced significantly stronger MLH-growth relationships than high moisture or low temperature. Even though low soil moisture and low temperature depressed growth to the same extent, the former produced MLH-growth relationships whereas the latter did not. Thus both environmental quantity and quality affected the existence and recurrence of MLH-growth relationships.
