SummaryThe predatory copepod Mesocyclops edax preys effectively on the rotifers Asplanchna girodi and Polyarthra vulgaris but not on the rotifer Keratella cochlearis. It readily captures individuals of this latter species but usually releases them unharmed, being unable to remove the soft parts within their loricae. The predatory A. girodi regularly eats K. cochlearis but cannot catch P. vulgaris. When P. vulgaris is contacted by the corona of A. girodi, it immediately escapes by elevating its…

The rotifer Euchlanis dilatata lives associated with submerged vegetation in the littoral zone of freshwater lakes and ponds. I assessed habitat-specific predation susceptibilities for this rotifer
Observations on the susceptibility of some protists and rotifers to predation by asplanchna girodi
TLDR
Coloniality and secretion of a gelatinous matrix in Conochilus can be viewed as adaptations to limit mortality from invertebrate predation.
Prey selectivity, functional response, and population growth of Asplanchna girodi de Guerne (Rotifera) fed four different brachionid prey
TLDR
It is suggested that prey morphology is an important determinant in prey selection by nonvisual predators such as Asplanchna girodi and therefore population growth rates would be highest on prey with small spines compared with those with long spines.
Predatory interactions between a cyclopoid copepod and three sibling rotifer species
TLDR
The differential vulnerability provides insight into the coexistence and seasonal succession of these competing rotifer species and shows that the competitive superiority of B. rotundiformis may be balanced by its greater vulnerability to copepod predation.
Predation of freshwater jellyfish on Bosmina: the consequences for population dynamics, body size, and morphology
TLDR
The significant increase in the size of adults and egg-carrying females as well as the increase in mucro and antennule length in medusaeenriched enclosures are discussed as defense strategies against the freshwater jellyfish.
Predation of freshwater jellyfish on Bosmina : the consequences for population dynamics, body size, and morphology
Invertebrate predators may cause strong changes in behaviour, life-history, and morphology of prey species. However, little is known about the influence of jellyfish on such characteristics of their
Vulnerability of cladoceran species to predation by the copepod Mesocyclops leuckarti: laboratory observations on the behavioural interactions between predator and prey
TLDR
Observations suggested that various defence mechanisms, including protruding structures and swimming behaviour and speed, are important in determining prey vulnerability, because larger animals were better able to escape Mesocyclops attacks.
Predatory interactions between Thermocyclops decipiens Kiefer (Cyclopoida : Copepoda) and two small cladocerans : behavior and prey post-encounter vulnerability
TLDR
It is suggested that intensity of mechanical perturbations and other size-dependent factors, but not body size alone, could be important in determining post-encounter prey vulnerability among individuals of a same species.
Vulnerability of rotifers and copepod nauplii to predation by Cyclops kolensis (Crustacea, Copepoda) under varying temperatures in Lake Baikal, Siberia
TLDR
Rotifers’ relatively high reproductive rate may present a mechanism to withstand predation should copepod’s preferred nauplii prey become less abundant in a warmer Baikal.
Predation by invertebrate predators on the colonial rotifer Sinantherina socialis
TLDR
The results suggest that the unpalatable nature of members of S. socialis to certain fishes extends to several invertebrate predators, but the nature of the putative factor(s) responsible for this remains unknown.

Competition in Cladoceran Communities: The Cost of Evolving Defenses against Copepod Predation
TLDR
An intimate relationship is apparent between fecundity and predator resistance in clones of the parthenogenic cladoceran Bosmina longirostris, and resulting differences in birth rate account for much of the rapid replacement of long-featured lines in the inshore regions after fishes remove predatory copepods.
Implications of copepod predation1
The copepod Epischura nevadensis selectively preys on zooplankton communities in a way that reduces the abundance of the cladoceran Bosmina Zongirostris and favors largerbodied species. Bosmina

TLDR
Direct observations of various predator-prey interactions between the different morphotypes of two taxonomically distinct clones show that the feeding responses of cannibals after actual prey contact are predictable and extremely selective.
Reduction of Zooplankton Standing Stocks by Predaceous Cyclops bicuspidatus thomasi in Marion Lake, British Columbia
TLDR
The standing stock of the copepod Cyclops bicuspidatus thomasi Forbes in Marion Lake, B.C., was observed during the summers of 1966 and 1967 and the predators ate nauplii in the same quantities as in the laboratory but, contrary to the laboratory results, very few rotifers.

TLDR
Investigations into the food relation of nannoplankton algae showed close relations to these algae groups and more over to μ-algae, and in spring the ChrysophyceaeErkenia subaequiciliata seems to be the most important food for the three Rotifer species.
Sexual reproduction in the rotifer Asplanchna girodi: Effects of tocopherol and population density†
TLDR
Populations containing undetectable levels of tocopherol exhibited normal sexual reproduction, indicating that this species and probably also A. brightwelli and A. sieboldi, do not require tocop herol for male fertility, and the hypothesis that toCopherol is an adaptive signal for mictic-female production in these latter two species by virtue of its role in male fertility is no longer tenable.
Control of feeding behaviour and selective cannibalism in the rotifer Asplanchna
SUMMARY. Feeding responses in campanulate females of Asplanchna sieboldi were induced with filtrates of homogenized saccate female clonemates, showing that such behaviour can be triggered entirely by
Rotifer Ecology and Embryological Induction
The rotifer Asplanchna releases into its environment a water-soluble, nondialyzable, pronase-sensitive factor which causes uncleaved eggs of another rotifer, Brachionus calyciflorus, to develop into
Fitness and Optimal Body Size in Zooplankton Population
TLDR
It is suggested that natural selection should lead to maximum reproductive effort at this size at the expense of growth, and several examples which support this idea are presented.
The Size-Efficiency Hypothesis and the Size Structure of Zooplankton Communities
TLDR
The size-efficiency hypothesis is an attempt to explain the commonly observed inverse relationship between the abundances of small and of large-bodied herbivorous zooplankton in freshwater lakes.
