Simultaneous Quantitative Comparison of Planktic Crustacea in Two Newfoundland Boreal Lakes
Abstract The number, size and reproductive potential of the planktic Crustacea were compared from March to December 1973 in two Newfoundland lakes, namely Hogans Pond and Bauline Long Pond. In the first period of the study the total number of microcrustaceans was greater in the more fertile Hogans P...

| Summary: | Abstract The number, size and reproductive potential of the planktic Crustacea were compared from March to December 1973 in two Newfoundland lakes, namely Hogans Pond and Bauline Long Pond. In the first period of the study the total number of microcrustaceans was greater in the more fertile Hogans Pond, but after October all species in Hogans Pond declined catastrophically. The relative numbers of individual species are detailed, some being more abundant in one lake and some in the other. Body lengths of most copepods were the same or greater in Hogans Pond than in Bauline Long Pond, but the cladoceran Daphnia catawba was larger in Bauline Long Pond. The number of eggs carried per female was usually the same or greater in Hogans Pond, except for Diaptomus minutus and Daphnia catawba in the spring. |
