Crossed induction of sex in sympatric congeneric rotifer populations
Crossed induction sex in sympatric congeneric rotifer populations
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...

Rotifera species collected from a pool (Çeltikli village, Bismil, Diyarbakır) 22 km from Bismil to Batman were surveyed taxonomically. Eighteen rotifer species were identified. Two of thes...
Chemical defense of the red tide dinoflagellate Karenia brevis against rotifer grazing
Chemical defense red tide dinoflagellate Karenia brevis against rotifer grazing
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...
With the aim of identifying the rotifer fauna of Lake Sazlıgöl, samples were collected monthly between February 1998 and July 1999, using a plankton net with a mesh size of 60 µm, and ...
Predation as a factor mediating resource competition among rotifer sibling species
rotifer sibling species Predation
2014/5/14
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
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
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 ...
