摘要
The cyclopoid copepod Thermocyclops crassus was collected in Missisquoi Bay, Lake Champlain, Vermont, U.S.A., in May and August 1991. Since this is the first confirmed record of the species in North America, the population is considered to be introduced. Thermocyclops crassus is widespread in temperate and tropical Eurasia and Africa, but, in the Americas, has been collected previously only in Costa Rica. It is planktonic and thermophilic, with a preference for eutrophic waters.
