The Rotifer Communities of Temporary Waters in Northeast Thailand.

Abstract

The rotifer communities from 456 temporary waters in northeast Thailand were investigated during the rainy seasons of 1999-2002. The samples were collected qualitatively from small temporary pools, shallow roadside canals and paddy fields, using a 30 μm mesh net. One hundred and twenty-seven species were identified. The majority of the species recorded are widely distributed tropical taxa similar to those found in the Thai permanent waters. The most diverse genus was Lecane with 37 species (29.1%), followed by Trichocerca (17 species, 13.4%), Brachionus (14 species, 11.0%), Lepadella (10 species, 7.9%), and Testudinella (6 species, 4.8%).
