Copepod reproduction is unaffected by diatom aldehydes or lipid composition
Copepod reproduction unaffected diatom aldehydes lipid composition
2014/4/21
We investigated whether reduced reproductive success of copepods fed with diatoms was related to nutritional imbalances with regard to essential lipids or to the production of inhibitory aldehydes. In...
The interactive effects of calcium concentration and temperature on the survival and reproduction ofDaphnia pulexat high and low food concentrations
calcium concentration temperature on the survival Daphnia pul exat high low food concentrations
2014/4/21
We rearedDaphnia pulexin a fully defined medium at seven calcium (Ca) concentrations (0.1, 0.5, 1, 1.5, 2, 5, and 10 mg Ca L21), two mixed algal densities (high food: 30mg chlorophyllaL21 and low food...

We investigated whether reduced reproductive success of copepods fed with diatoms was related to nutritional imbalances with regard to essential lipids or to the production of inhibitory aldehydes. In...
Phytoplankton essential fatty acid and phosphorus content constraints on Daphnia somatic growth and reproduction
Phytoplankton essential fatty acid phosphorus content constraints Daphnia somatic growth reproduction
2014/5/5
We performed 12 experiments where the herbivorous zooplankter Daphnia pulex was fed three different phytoplankton food types (cyanophytes, chlorophytes, or cryptophytes) at two phosphorus (P) deficien...
Barnacle larvae in ice: Survival, reproduction, and time to postsettlement metamorphosis
Barnacle larvae in ice Survival reproduction postsettlement metamorphosis
2014/5/13
Late stage larvae (cyprids) of the barnacle Semibalanus balanoides frequently encounter freezing conditions along the northwest Atlantic coast. S. balanoides cyprids survived for more than 4 weeks emb...
Differential effects of phosphorus and fatty acids on Daphnia growth and reproduction
phosphorus and fatty acids Daphnia growth and reproduction
2014/5/8
We investigated the effects of various mineral and biochemical limitations on Daphnia magna. These daphniids have much lower saturation thresholds for growth for the polyunsaturated fatty acids (PUFA)...
Relevant scales in zooplankton ecology: Distribution, feeding, and reproduction of the copepod Acartia hudsonica in response to thin layers of the diatom Skeletonema costatum
Relevant scales zooplankton ecology Distribution feeding reproduction copepod Acartia hudsonica thin layers diatom Skeletonema costatum
2014/5/14
We investigated the interaction of the copepod Acartia hudsonica in relation to thin layers of the diatom Skeletonema costatum. Thin layers have recently received much attention, since they are common...
Induction of sexual reproduction in Brachionus plicatilis (Monogononta, Rotifera) by a density-dependent chemical cue
sexual reproduction Brachionus plicatilis Monogononta, Rotifera density-dependent chemical cue
2014/5/20
Induction of mixis (sexual reproduction) in rotifers of the genus Brachionus is believed to be triggered by a chemical that is released into the water and accumulates at high population densities. How...
Zooplankton survival and reproduction responses to damaging UV radiation: A test of reciprocity and photoenzymatic repair
Zooplankton survival reproduction responses damaging UV radiation A test of reciprocity photoenzymatic repair
2014/6/9
As stratospheric ozone concentrations are reduced, exposure of organisms to damaging ultraviolet radiation (UVR) reaching the earth increases. Many organisms can repair DNA damaged by UVR through phot...
