An ecological study of some littoral freshwater microcrustaceans (Cladocera and Copepoda) in Newfoundland
Samples were obtained in the littoral region of 74 waters from various parts of the Province of Newfoundland and Labrador. The Cladocera and Copepoda found in the collections were listed. Sixty-two species were recorded which included 47 species of Cladocera and 15 species of Copepoda. Twenty-six sp...
