Notes on the systematics and ecology of Daphnia pulex LEYDIG in Northern Canada
Abstract Daphnia populations from the region of Yellowknife (N. W. T.) on the Great Nave Lake, from Tuktoyaktuk (N. W. T.) on the coast of the Beaufort Sea east of the Mackenzie‐Delta, and from Shingle Point (Y. T.) west of the Mackenzie‐Delta were described. Population diagrams were given for the b...
