Survival
no changein H. oligactis1
Food availability has no effect on survival in H. oligactis.
“survival rate was not affected by the amount of food.”

Fecundity
upin H. oligactis1
Food availability increases fecundity in H. oligactis.
“Food availability significantly affected fecundity (number of eggs or testes produced), with the largest number of gonads being produced by animals kept on a high food regime.”

Selection favoring longer zooid longevity
upin S. marine1
Food availability is associated with selection favoring longer zooid longevity in S. marine.
“In environments where food availability is high and flow rate is low, selection also favours colonies with longer zooid longevity.”
