Thermokarst lakes and ponds were sampled across a range of permafrost landscapes in subarctic QuĂŠbec (Nunavik, Canada), to compare their rotifer and other zooplankton characteristics with a set of rock-basin lakes and ponds in the region. A total of 24 rotifer species were identified, with an average of 7 taxa per waterbody. Rotifer abundance was an order of magnitude higher in the thaw ponds than in rock-basin waters. In some thaw ponds, rotifers accounted for >50% of the total zooplankton biomass, but for The accepted manuscript in pdf format is listed with the files at the bottom of this page.
