Haplotypic differentiation between seasonal populations of Sargassum horneri (Fucales, Phaeophyceae) in Japan

SUMMARY Conspecific populations with different life‐cycle seasonality, particularly of their reproductive season, have been reported for many seaweed species. However, the number of genetic analyses of such seasonal populations is limited. Herein, based on the mitochondrial cytochrome oxidase subunit 3 gene ( cox 3) haplotype, we evaluated the genetic diversity of winter (January–March) and spring (April–June) fertile populations of the brown...
