Popis: Using a combination of clone library and DGGE analyses, we assessed the diversity of coastal planktonic ciliates from the oligotrich and choreotrich clades across environmental gradients in Long Island Sound, USA. We sampled fresh and saline, as well as stratified and well-mixed, waters and found that these ciliate assemblages consist of a few common haplotypes and numerous rare haplotypes. Rarefaction estimates of total richness indicated that our survey did not cover the full diversity of the samples, suggesting that there may be many more haplotypes present in the Sound than predicted by previous microscopic surveys. We also found that haplotype richness varied on small spatial scales (
