Crossed induction of sex in sympatric congeneric rotifer populations
Crossed induction sex in sympatric congeneric rotifer populations
font style='font-size:12px;'>
2014/4/17
The transition from asexual to sexual reproduction in rotifers of the genus Brachionus(Monogononta) is triggered by a chemical signal produced and released by the rotifers themselves; the signal accum...
Chemical defense of the red tide dinoflagellate Karenia brevis against rotifer grazing
Chemical defense red tide dinoflagellate Karenia brevis against rotifer grazing
font style='font-size:12px;'>
2014/4/22
In order to test whether phytoplankton such as the red tide dinoflagellate Karenia brevis negatively affect rotifer grazers and what mechanisms are involved in these interactions, we conducted laborat...
Infochemical-mediated trophic interactions between the rotifer Brachionus calyciflorus and its food algae
Infochemical-mediated trophic interactions he rotifer Brachionus calyciflorus

2014/4/22
We studied how chemicals obtained as filtrates from algal monocultures (algal chemicals) and from rotifer
cultures with or without algae (rotifer chemicals) affected feeding rates of the rotifer Brac...

The relevance of predation as a factor mediating the competitive interaction among ecologically very similar
species is investigated by experimentally analyzing the effect of the copepod predator Dia...
Specificity of crowding response that induces sexuality in the rotifer Brachionus
Specificity of crowding response induces sexuality rotifer Brachionus
font style='font-size:12px;'>
2014/5/20
Crowding induced the production of mictic (male-producing) females in Brachionus calyciflorus from two North American strains and an Australian strain. The specificity of this response to crowding was...
Nutrient limitation on a planktonic rotifer: Life history consequences and starvation resistance
Nutrient limitation planktonic rotifer Life history consequences starvation resistance
font style='font-size:12px;'>
2014/5/20
Nutrient content of plants is low relative to that of herbivores. Dietary nutrients can limit the growth and reproduction of herbivores. We studied life history consequences and starvation resistance ...
