Combined effects of food quality and temperature on somatic growth and reproduction of two freshwater cladocerans
Combined effects of food quality somatic growth
font style='font-size:12px;'>
2014/4/18
We investigated the effect of food quality on somatic growth and reproduction of zooplankton at different
temperatures (12uC, 15uC, 20uC, and 25uC). Standardized growth experiments of two cladocerans...
Copepod reproduction is unaffected by diatom aldehydes or lipid composition
Copepod reproduction unaffected diatom aldehydes lipid composition
font style='font-size:12px;'>
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

2014/4/22
Cumulative incorporation of radiolabeled algal (NaH14
CO3) and bacterial (14
C-acetate) carbon associated with
benthic organic matter (BOM) was measured at timed intervals to determine the relative...
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
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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...
Reproduction as one of the main causes of temporal variability in the elemental composition of zooplankton
Reproduction temporal variability
font style='font-size:12px;'>
2014/5/13
With the aim to determine the contribution of development and reproduction to the variability in the elemental
composition of zooplankton, we measured the carbon (C), hydrogen (H), nitrogen (N), and ...
Differential effects of phosphorus and fatty acids on Daphnia growth and reproduction
phosphorus and fatty acids Daphnia growth and reproduction
font style='font-size:12px;'>
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)...
Nonrandom sexual reproduction and diapausing egg production in a Daphnia hybrid species complex
Nonrandom sexual reproduction
font style='font-size:12px;'>
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...
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
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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
