Genetic structure and congeneric range overlap among sharpnose sharks (genus Rhizoprionodon ) in the Northwest Atlantic Ocean
Sharpnose sharks (genus Rhizoprionodon) experience extensive fishing pressure throughout their ranges in the Atlantic Ocean. As such, it is important to understand the degree to which intraspecific populations interact across a spatial gradient. The Atlantic sharpnose shark (Rhizoprionodon terraenov...
