Reproductive effort in Daphnia galeata : comparison of reservoir and pond populations

Populations of Daphnia galeata from the deep stratified moderately eutrophic reservoir and the shallow highly eutrophic carp ponds differed in the reproductive effort of the first laboratory generation cultivated at a rich algal diet. The reservoir animals were smaller at the first adult instar and...

Description
Summary:Populations of Daphnia galeata from the deep stratified moderately eutrophic reservoir and the shallow highly eutrophic carp ponds differed in the reproductive effort of the first laboratory generation cultivated at a rich algal diet. The reservoir animals were smaller at the first adult instar and exhibited longer time between hatching of one brood and forming the eggs of the next one.
