Rotifers, due to their short generation time and their reproductive mode, show rapid local adaptations, making them useful indicators of environmental change. Fulks, W. & K. L. Main (eds), 1991. Other adaptations include sheaths that are made of a gel-like substance and ion replacement. Experimental results showed relatively high survival rates (82–85%) in rotifers that were cultured at 25 °C and exposed later to -1 °C for 12–14 days.

Chemical composition of dietary species of marine unicellular algae and rotifers with emphasis on fatty acids. These results support the hypothesis of specific adaptations to survival at low temperatures during an acclimation period. Hydrobiol. Coexistence of rotifer (Brachionus plicatilis) clones in Soda Lake, Nevada. Moreover, the pattern of variation in r revealed genetic differences among clones collected at different times. Physiological adaptations in the survival of rotifers (Brachionus plicatilis, O. F. Müller) at low temperatures. If either of these conditions does not hold,the population is expected to be subdivided into a number of genetically discrete units, each unit occupying a different temporal part of the environmental mosaic. Rotifers are microscopic aquatic animals of the phylum Rotifera. Since the discovery of the Loricifera (Kristensen, 1983) 11 species have been described (Higgins and Kristensen, 1986; Kristensen and Shirayama, 1988; Todaro and Kristensen, 1998), and more than 80 recorded species await description (Kristensen, 1991a, b; Gad, 2000).

To test this hypothesis, rotifers (Euchlanis dilatata) were periodically collected from a nature, cloned, allowed to adapt to the laboratory environment for 10 generations, and then used in experiments to determine the intrinsic rate of population growth, r. The r values of clones collected at different times indicated that physiological adaptation alone is not the major factor involved in adaptation to seasonal variation.

Lubzens, E., 1989. But rotifers possess a unique combination of traits that distinguish them from other animals, including bilateral symmetry and a pseudocoelom , a fluid-filled body cavity between two different layers of embryonic tissue.

Hirata, H., 1980. There are over 450 described species of bdelloid rotifers (or 'bdelloids'), distinguished from each other mainly on the basis of morphology. Rotifer genetics: integration of classic and modern techniques. Egg ratios (egg count/rotifer count) typically range from 0.25 to 0.5, but an egg ratio of 0.25 in a heavily harvested culture is sufficient to double the population daily (because a rotifer can lay more than one egg per day). Aquatic and wetland plants do not belong to any one particular plant family. These included the type of food fed to rotifers (yeast or algae), the salinity in which they were cultured, and an essential acclimation period of 2–6 day at 4 °C or 10 °C.

Hydrobiologia 313, 175–183 (1995). In one such adaptation, the eggs or larvae are distasteful, inedible, or apparently harmful to potential enemies. The third chapter considers two major evolutionary features of rotifers: parthenogenetic reproduction, which is correlated with feeding, and special adaptations promoting survivorship in harsh environments (anhydrobiosis in Bdelloïdea, resting eggs production in Monogononta).

Biophysics and Biochemistry at Low Temperatures. Rotifers feed on microalgae and are consumed by a wide variety of fish, shellfish, corals, and other organisms. In some species, stems arch over and take root at their tips, forming new plants. To test this hypothesis, rotifers (Euchlanis dilatata) were periodically collected from a nature, cloned, allowed to adapt to the laboratory environment for 10 generations, and then used in experiments to determine the intrinsic rate of population growth, r. 43: 1147–1155. 83: 415–424. To withstand such environmental conditions, tardigrades, as well as some nematodes and rotifers, enter a completely desiccated state known as anhydrobiosis. Russel, N. J., 1990.
