Deep segregation in the open ocean: Macaronesia as an evolutionary hotspot for low dispersal marine invertebrates.

abstract：:Digital gene expression (DGE) analysis offers a route to gene discovery which by-passes the need to develop bespoke arrays for nonmodel species, and is therefore a potentially valuable tool for molecular ecologists. Scottish blackface sheep, which vary in resistance to the common abomasal parasitic nematode Teladorsag...
