Biodiversity hotspots host a high diversity of narrowly distributed endemic species, which are increasingly threatened by climate change. In eastern North America, the highest concentration plant and endemism occurs in Southern Appalachian Mountains (SAM). It has been hypothesized that this region served as refugium during Pleistocene glacial cycles postglacial migration northward was dispersal...

This research involved in and coordinated multidisciplinary and complementary natural resources in the area of sustainable soil and plant nutrient management as well as economic benefits of edible herb production systems. The main concern was selection of the right growing media to achieve optimum yield and growth rate while avoiding application of synthetic fertilizers.Froriepia subpinnata is ...
