| Abstract |
Melosira granulata and M. islandica occur sympatrically in the Laurentian Great Lakes, but maximum population abundance of the two species occurs at opposite ends of the range of seasonal and trophic conditions found in the system. Both species are polymorphic, but are distinguishable on the basis of a number of morphological characteristics. Their distribution and the range of morphologic variation encountered in populations from the Great Lakes is summarized and discussed. Although ranges in size and computed cell volumes of populations of the two species overlap, there are significant differences in cellular composition. Cells of M. islandica contain a much larger fraction of living cytoplasm and cell wall material than cells of M. granulata. (Copyright (c) Internat. Assoc. Great Lakes Res., 1981.) |
