“…High absolute reproductive rates and high temperatures ensure that new recruits will greatly outnumber the older members of the population. Conversely, decreases in temperature increase adult lifespan while slowing the maturation of immatures (MacArthur and Baillie, 1929) and as a result act to reduce the turnover rate of the adult population. Such an effect can be seen clearly in the present results.…”

“…When food is abundant, parthenogenetic eggs are released into the brood pouch after each moult of adult life. Embryogenesis occurs in the pouch and from two (at 200 C.) to ten (at 8° C.) days elapse before the young are released (MacArthur and Baillie, 1929). The number of young in a brood can vary from 1 to over 100 and is directly related to food availability.…”

“…The life spans we saw in the laboratory suggest that substantial numbers of D. pulicaria may live long enough to cross the seasonal troughs of habitat quality because the average temperature and resource level they experience in the field is lower than laboratory conditions. Daphnid life spans have been shown to lengthen in colder temperatures (MacArthur and Baillie 1929;Ingle 1933) and under reduced resources (Ingle et al 1937). When resources increase in spring and fall, a population of D. pulicaria will be composed mainly of large adults that persisted from the last good season.…”

“…As males require almost three times as long to reach the fourth instar at 10 8C (17 days) than at 20 8C (6 days) (M. C. Brewer, unpublished data), juveniles could bene¢t considerably by remaining in the warm water to mature as fast as possible. After maturing, movement down into cold water would increase their longevity (MacArthur & Baillie 1929), which could in turn increase their lifetime encounter rate with females. The importance to the small males of remaining in warm water, and its potential tradeo¡ with predation risk, is illustrated by the distributions in experiment 3.…”
