Genetic diversity and population structure of Capitulum mitella (Linnaeus, 1767) in Fujian (China) revealed by mtDNA COI sequences.

ABSTRACT: Background: Capitulum mitella is a widely distributed and ecologically important stalked barnacle that settles extensively on rocky shores. This species contributes to the structural complexity of intertidal habitats and plays a critical role in the marine ecosystem. This study aimed to reveal the genetic diversity and population structure of C. mitella by analyzing the mitochondrial cytochrome oxidase I (COI) gene. Methods: A 683bp fragment of the COI gene was sequenced from 390 individuals sampled from six localities in Fujian, China. Results: A total of 84 distinct haplotypes were identified through the analysis of 82 polymorphic sites, resulting in an average haplotype diversity (h) of 0.660 and nucleotide diversity (π) of 0.00182.
