Hi everybody,
I am searching a paper (if any) reporting the rate of nucleotidic substitution of mitochondrial gene COI for Pinctada species (Mollusca, Bivalvia, Pteroidea). In case it does not exist, a value for closely related molluscs would be ok. I checked the literature for bivalve molluscs and I found a very high degree of heterogeneity across substitution rates.
