The rotifer species present in samples from 180 small water bodies, or ponds, in England were identified and listed for each pond . These communities were used to provide a system of classification of ponds applicable on a national basis, using the program 'TWINSPAN' . Sites were also ordinated using 'DECORANA' to identify major trends within the data set . The environmental factors most highly correlated with rotifer community were : (a) conductivity (P< 0.001), (b) pH (P< 0.001) and (c) permanence of water body (P<0 .001) . Out of 167 species, 32 were acting as indicators . It is suggested that a pond classification could be based on these species alone .

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
