Genetic and environmental effects on morphology in clonal sedges in the Eurasian Arctic
We studied the variation in morphological characters of importance for resource acquisition and storage in 21 populations of four clonal sedge taxa in arctic Eurasia, Carex bigelowii , C. ensifolia subsp. arctisibirica , C. lugens , and C. stans , and the response to transplantation to a common gard...

We studied the variation in morphological characters of importance for resource acquisition and storage in 21 populations of four clonal sedge taxa in arctic Eurasia, Carex bigelowii , C. ensifolia subsp. arctisibirica , C. lugens , and C. stans , and the response to transplantation to a common garden in Tromsø, Norway. The morphology of C. stans was distinct from the other three taxa, all of which belong to the C. bigelowii species complex. However, differences among populations within taxa were even greater than differences among taxa, and environmental variables explained 40–50% of the among‐population variation in the morphological characters. Stomatal size decreased with temperature while stomatal density increased. Shoot height and leaf width were smaller at peak lemming population phase, while rhizome length was shorter at higher longitudes. Transplantation to a common garden affected stomatal density in all taxa, stomatal size and shoot height only in some taxa, while leaf width was not affected. We found a weak, but highly significant correlation between geographical, morphological, and genetic distances. We concluded that although genotypic differentiation in arctic rhizomatous Carex species is reflected in their morphology, they are also capable of plastic morphological responses to the environment and that these responses are specific for each taxon. |
