Suppression of rotifer populations by Daphnia: A review of the evidence, the mechanisms, and the effects on zooplankton community structure1
There is strong evidence that rotifers cannot become abundant members of freshwater zooplankton communities in the presence of large Daphnia, and small cladocerans generally do not mechanically interfere withRotifers, are less likely to deplete food resources, are themselves more likely to be suppressed by exploitative competition with rotifer, and usually are more susceptible to invertebrate predation.
Suspended Clay and the Population Dynamics of Planktonic Rotifers and Cladocerans
The presence of suspended sediments in natural ecosystems, such as turbid lakes and reservoirs, should favor rotifers over cladocerans and thus influence the structure of zooplankton communities.
Sleep in Mammals : Ecological and Constitutional Correlates
The interrelationships between sleep, ecological, and constitutional variables were assessed statistically for 39 mammalian species and found that both constitutional and ecological influences are important predictors of the amount and type of sleep obtained by mammals.
Competition between Rotifers and Daphnia
Rotifers, whose food niches are included with those of cladocerans, may be rapidly excluded by large cladocers through both exploitative and interference competition; they are unlikely to abound in zooplankton communities with large cladOCerans unless food is abundant or environmental factors differentially inhibit the cladocerrans.

Body Size, Food Concentration, and Population Growth in Planktonic Rotifers
Because the smallest species have the lowest threshold food levels and the food levels necessary for them to attain rm,,a/2 are lowest, they appear well adapted to living in food-poor environments and large species appear to be restricted to food-rich environments but may thrive there because of their high reproductive potential.
Differential Effects of Anabaena Affinis on Cladocerans and Rotifers: Mechanisms and Implications
Experiments indicated that a sensitive strain of Daphnia pulex was inhibited by ingesting an A. a//nis endotoxin, indicating a co-evolved resistance to the toxin, possibly a counter to an antiherbivore defense and the relative importance of rotifers in zooplankton communities.
