QTL linkage mapping of wing length in zebra finch using genome-wide single nucleotide polymorphisms markers.

abstract：:Although many sharks begin their life confined in nursery habitats, it is unknown how rapidly they disperse away from their natal area once they leave the nursery. We examine this issue in immature lemon sharks (Negaprion brevirostris) from the time they leave the nursery (approximately age 3) at a subtropical island ...
