Modeling Climate-Dependent Larval Growth Rate and Duration of Olympia oysters in the Salish Sea
Most invertebrates in the ocean begin their lives with a planktonic larval phase that is of utmost importance for dispersal and distribution of these species, especially for organisms that are sessile or otherwise mobility-limited during adult life. As larvae are particularly vulnerable to environme...
