Zooplankton life cycles pelagic births
2014/5/16
Zooplankton demographics operate over multiple time scales corresponding to pelagic parthenogenetic generations, an overwintering stage, and an ‘‘egg bank.’’ Comparisons of pelagic birth and death rat...
Nonrandom sexual reproduction and diapausing egg production in a Daphnia hybrid species complex

Sexual reproduction in Daphnia results in the production of diapausing eggs, which are enclosed in a structure
called ephippium. Ephippia, accumulated by sedimentation, can be preserved for decades a...
Supplementation of a diatom diet with cholesterol can enhance copepod egg-production rates
a diatom diet cholesterol copepod egg-production rates
2014/5/14
Cholesterol is required for animal growth, yet it cannot be biosynthesized de novo by crustaceans. Dietary sterols are thus necessary for the growth and reproduction of copepods. Sterols vary widely i...
