Abstract
Food consumption, body size and budding rate were measured simultaneously in isolated individual hydra of 6 strains. For each individual hydra the 3 measurements define a point in the 3 dimensional space with axes: food consumption, budding rate and body size. These points lie on a single surface, regardless of species. Floating rate and incidence of sexuality map onto this surface. This surface probably is an example of a general class of evolutionary constraint surfaces derived from the conjuction of evolution theory and the theory of ecological resource budgets. These constraint surfaces correspond to microevolutionary domains.This publication has 2 references indexed in Scilit:
