- In California, _O. dioica_ was reported by C. Essenberg
([[1922|biblio/1929090]]) to be rare in summer's warm (> 20ºC) waters and
more abundant in winter's cool (13~16 ºC) waters.
+ - _O. dioica_ was found throurought the North Pacific by ([[Tokioka (1960)|biblio/10.5134_174644]]).
- _O. dioica_ has “a very large mutation rate, and/or a very large effective
population size” ([[Denoeud et al., 2010|biblio/21097902]], according to a study
of silent and non-silent substitution rates in coding sequences).
