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 (z 1.2 mm) Daphnia. Indirect evidence comes from fieldExpand

Suspended Clay and the Population Dynamics of Planktonic Rotifers and Cladocerans
The direct and indirect effects of suspended clay on the population dynamics of several species of planktonic rotifers and cladocerans were investigated using long-term laboratory experiments. LifeExpand

Sleep in Mammals : Ecological and Constitutional Correlates
The interrelationships between sleep, ecological, and constitutional variables were assessed statisticallyfor 39 mammalian species. Slow-wave sleep is negatively associated with a factor related toExpand

Competition between Rotifers and Daphnia
This study examined the ability of two rotifers to coexist with a large cladoceran. Laboratory competition experiments using daily renewed batch cultures showed that Brachionus calyciflorus andExpand

Brachionus calyciflorus is a species complex: Mating behavior and genetic differentiation among four geographically isolated strains
Four geographic strains of B. calyciflorus are investigated regarding their genetic similarity and ability to cross-mate. DNA sequence analysis of the mitochondrial cox1 gene (694 bp) and the nuclearExpand

Body Size, Food Concentration, and Population Growth in Planktonic Rotifers
Population growth rates of eight species of planktonic rotifers were assessed for five to seven food concentrations using daily renewed batch cultures. The food concentration for which populationExpand

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 intoExpand
