INTRODUCTION Species from the genus Cuphea, Lythraceae, are known to produce seed rich in medium chain fatty acids (MCFA), which are important feed-stocks in the manufacturing of soaps and detergents and numerous other related products (Thompson 1984). In the US there are no crops grown that serve as an economical replacement of MCFA. Consequently, the US chemical industry imports most MCFA as ...

Study of adaptive evolutionary changes in populations of invasive species can be advanced through the joint application of quantitative and population genetic methods. Using purple loosestrife as a model system, we investigated the relative roles of natural selection, genetic drift and gene flow in the invasive process by contrasting phenotypical and neutral genetic differentiation among native...
