A population study of killer viruses reveals different evolutionary histories of two closely related Saccharomyces sensu stricto yeasts.

abstract：:The geographic distributions of marine fishes have been shaped by ancient vicariance and ongoing dispersal events. Some species exhibit anti-equatorial distributions, inhabiting temperate regions on both sides of the tropics while being absent from equatorial latitudes. The perciform fish Microcanthus strigatus (the s...
