“…This is referred to as adaptive phenotypic plasticity (Moller et al 1990). Thus, if a gene arose destroying plasticity, it would be outcompeted if unseasonal rains fell that produced enough vegetation to allow young snails to survive through the summer, because individuals possessing this gene would be unable to reproduce.…”

“…Thus, if a gene arose destroying plasticity, it would be outcompeted if unseasonal rains fell that produced enough vegetation to allow young snails to survive through the summer, because individuals possessing this gene would be unable to reproduce. On the other hand, if a snail reproduced at the onset of unseasonal rains, but these rains were insufficient to sustain growth of young snails, a gene for phenotypic plasticity would be selected against, relative to the conservative gene without plasticity (Moller et al 1990). …”

“…A "jack-of-all-trades" allele (Moller et al 1990) that, although outcompeted in a growth-favored and reproduction-favoured environment, has higher longterm fitness (Caswell 1983;Segers and Brockmann 1987).…”

In the Negev desert of Israel, the pulmonate land snailTrochoidea seetzeni is active, grows and reproduces in the month following the torrential winter rains. Thereafter, these snails estivate until the following year's rains. By experimental supplementation of water in the field, we examined the ability of these snails to alter their life histories. Specifically, we measured changes in feeding activity, overall activity levels, movement patterns and reproductive output. We found that snails on artificially-watered plots stopped feeding on higher plants and fed on soil-surface algae growing as a result of increased water availability. Most snails moved onto the watered plots, and reduced the total amount of movement once there, in response to increased food availability. Snails on the watered plots grew more and remained active for a longer period into the summer months than did snails on control plots. However, we found little evidence for the ability of these snails to alter their reproductive outputs in response to increased water (and hence food) availability. There was also no carry-over effect of high water availability in one season enhancing reproduction in the following season. We postulate that the low level of phenotypic plasticity recorded here is a consequence of an adaptive conservative strategy to maintain a high reproductive output under extremely unpredictable desert conditions.

“…However, there are other possible implications of this decision. Moller et al (1990) found a negative correlation between development time and fecundity, which may be responsible for the decrease in the number of eggs laid in later generations, seen most especially on the adzuki beans, as the effects of the artifi cial selection for the development rate became stronger with each generation.…”

“…Nije bilo značajnih razlika između kontrolne i grupa gajenih u prisustvu kadmijuma u veličini koeficijenata korelacije kod ženki. U istraživanjima na Drosophila-ma rezultati su pokazali značajnu korelisanost mase i ranog fekunditeta (Hillesheim and Stearns, 1992), ali i brzine larvenog razvića i mase, pri čemu su jedinke sa bržim larvenim razvićem imale manju masu (Moller et al, 1990). …”
