The role of fine-scale habitat heterogeneity on within-population genetic divergence is studied in North American Arabidopsis lyrata (Brassicaceae) inhabiting a sand dune landscape. Wos and Willi relate site-of-origin...
For conservation of rare riparian species, avoiding an impact to hydrodynamic processes, such as water tables and flooding dynamics, may be just as critical as avoiding direct impacts on the number of plants.
