A simple model relating habitat features to a diapause egg bank
A simple model relating habitat features a diapause egg bank
2014/5/4
As a way to escape from adverse conditions, many zooplankton populations produce diapausing eggs that accumulate in the sediments and hatch when suitable environmental conditions are restored. While b...
Food quality controls egg quality of the zebra mussel Dreissena polymorpha: The role of fatty acids
zebra mussel Dreissena polymorpha egg
2014/5/19
We investigated the investment of adult Dreissena polymorpha to the eggs by sampling mussels monthly from
4- and 15-m water depth. The fatty acid composition of eggs differed significantly betw...
Zooplankton life cycles: Direct documentation of pelagic births and deaths relative to diapausing egg production
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
Nonrandom sexual reproduction
2014/5/16
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...
Zooplankton recovery after fish removal: Limitations of the egg bank
Zooplankton recovery bank
2014/5/16
The Allee effect, operating via mate limitation, theoretically reduces the probability of recovery from local
extinction of dioecious zooplankton relative to species that can reproduce asexually. We ...
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...
A comparison of egg-bank and long-term plankton dynamics of two Daphnia species, D. hyalina and D. galeata: Potentials and limits of reconstruction
egg-bank and long-term plankton dynamics two Daphnia species, D. hyalina and D. galeata Potentials and limits of reconstruction
2014/5/21
Resting eggs of planktonic organisms from datable sediment cores are increasingly used to reconstruct historical information on the abundance, size, genetic composition, and microevolution of plankton...
Feeding selectivity and egg production of Calanus helgolandicus in the English Channel
Feeding selectivity egg production Calanus helgolandicus English Channel
2014/6/17
Copepods are able to discriminate between different foods on the basis of particle size and nutritional quality. However, the extent of selective feeding behavior and the mechanisms controlling it in ...
