Abstract
Here I evaluate the population genetic structure of the barnacle Jehlius cirratus across a broad portion of its geographic distribution using data from the mitochondrial cytochrome oxidase I (COI) gene region. Despite sampling diversity from close to 3000km of the linear range of this barnacle, there is little evidence for population structure. Hudson's Snn value across all sites is not significantly different from null expectation, and no other phylogeographic structure is evident. Unbalanced sample sizes and their effect on such population genetic and phylogeographic analyses are discussed, but the general conclusion of this study is that J. cirratus can be considered panmictic along the Chilean coast.
Author Comment
This is an updated version of the preprint (removed 4 poor sequences from v1; added 9 sequences, including 4 individuals from location >500km further to the south; results are effectively the same; R coding is improved).
