A direct test of cyanobacterial chemical defense: Variable effects of microcystin-treated food on two Daphnia pulicaria clones
cyanobacterial chemical defense microcystin-treated food two Daphnia pulicaria clones
2014/4/22
To determine the direct effects of microcystin on the fitness of herbivorous zooplankton, we experimentally added microcystin-LR to freeze-dried cells of palatable Chlorella and fed these compound-tre...
Local adaptation of Daphnia pulicaria to toxic cyanobacteria
Local adaptation Daphnia pulicaria toxic cyanobacteria School of Biology, Georgia Institute of Technology,
2014/5/13
We quantified within-species variation in the tolerance of the large, lake-dwelling daphnid, Daphnia pulicaria, to toxic cyanobacteria in the diet. Juvenile growth rates on diets consisting of 100% An...
Life history responses of Daphnia pulicaria to diets containing freshwater diatoms: Effects of nutritional quality versus polyunsaturated aldehydes
Daphnia pulicaria diets containing freshwater diatoms nutritional quality polyunsaturated aldehydes
2014/5/9
Like marine diatoms, some freshwater diatoms produce α, β, γ, δ-polyunsaturated aldehydes (PUA) when damaged. Some of these oxylipins are suspected of impairing egg viability in marine copepods. To de...
Effects of Microcystis aeruginosa and purified microcystin-LR on the feeding behavior of Daphnia pulicaria
Effects of Microcystis aeruginosa purified microcystin-LR feeding behavior Daphnia pulicaria
2014/5/14
We investigated the mechanisms behind the negative effects of cyanobacteria on zooplankton by comparing the effects of Microcystis aeruginosa single cells, colonies, and toxins on the feeding behavior...
Evidence of a mutualistic relationship between an algal epibiont and its host, Daphnia pulicaria
a mutualistic relationship an algal epibiont and its host Daphnia pulicaria
2014/6/9
We examined seasonality, intensity, and level of epibiont infection by the green alga Korshikoviella gracilipes on the zooplankton community over 2 yr in the high mountain Rio Seco lake. Daphnia pulic...
