Reproductive potential of the earthworm Eisenia foetida

  title={Reproductive potential of the earthworm Eisenia foetida},
  author={Roy Hartenstein and Edward F. Neuhauser and David L Kaplan},
Regression equations are provided for the earthworm Eisenia foetida with respect to age at which 50% of the population became clitellate at 25° C in relation to population density in activated sludge and in horse manure. Regression equations are provided for progeny per cocoon versus weight of cocoon, and weight of cocoon in relation to weight of parent; from these an equation is derived for progeny per cocoon relative to worm weight. Regression equations are given on (a) number of cocoons… CONTINUE READING
