Abstract
A survey of Greiner Lake in Victoria Island revealed the presence there of 4 species usually considered to be "relicts" of marine or glacial events. The species are: Mysis relicta. Limnocalanus macrurus. Gammaracanthus loricatus aestuariorum and Mesidothea entomon. M. entomon is a new record for fresh waters isolated from contact with the sea in North America and G. loricatus aestuariorum is a new record for this region. Greiner Lake (15 m above sea level) is in an area that has risen from the sea within the last 1300 years. It has a maximum depth of 11 m and a maximum summer temperature of approximately 8[degree]C. An analysis of the lake water is given and also a brief account of other species present. Possible methods for the arrival of the relicts in Victoria Island are discussed.This publication has 0 references indexed in Scilit:
