Parasite genetic distance and local adaptation in co-evolving bacteria-bacteriophage populations.

abstract：:Understanding the pattern of connectivity among populations is crucial for the development of realistic and spatially explicit population models in marine systems. Here we analysed variation at eight microsatellite loci to assess the genetic structure and to infer patterns of larval dispersal for a brooding coral, Ser...
