- Carexsection Scirpinae(Cyperaceae) is a small, monophyletic group of predominately North American sedges, several of which are edaphic endemics of recent origin, including Carex scirpoideasubsp. convoluta. Here we test the hypothesis of lower genetic diversity in the narrow edaphic endemic C. scirpoideasubsp. convolutarelative to its geographically widespread conspecific subsp. scirpoidea.
It is expected that natural selection imposed by soil chemistry will result in low levels of genetic diversity in edaphic endemics in comparison to their widespread relatives (Rajakaruna 2004). Widespread taxa are also expected to maintain high levels of genetic diversity due to a number of other factors, including adaptation to a wide range of environmental conditions. Widespread taxa are also expected to show genetic structure due to limited gene flow (Gitzendanner and Soltis 2000). Here we used allozyme analysis to describe population genetic diversity and structure in the narrow edaphic endemic, Carex scirpoideasubsp. convoluta, relative to its widespread conspecific.
