Where restoration efforts occur, such as with Ostrea lurida in Puget Sound, Washington, it is important to consider genetic population structure. Traits that hold adaptive advantage such as reproductive timing and stress resilience may differ at local scales. Using three established populations of O.lurida within Puget Sound Washington, we performed a reciprocal transplant experiment and monitored survival, growth, reproduction. We found that performance differed for each population at each of these three metrics. O.lurida from a relatively harsh home site environment with low primary production and high dynamic habitats exhibited generally greater survival at all sites, whereas those from a relatively lush home site environment with high primary production and lower habitat dynamics exhibited generally greater reproductive activity at all sites. Populations from sites with shorter growing seasons exhibited greater growth in sites with longer growing periods, suggesting a countergradient adaptation may have occurred in these populations.

For long term persistence of species, it is important to consider population structure. 28 Traits that hold adaptive advantage such as reproductive timing and stress resilience may differ 29 among locales. Knowledge and consideration of these traits should be integrated into 30 conservation efforts. A reciprocal transplant experiment was carried out monitoring survival, 31 growth, and reproduction using three established populations of Ostrea lurida within Puget 32 Sound, Washington. Performance differed for each population. Ostrea lurida from Dabob Bay 33 had higher survival at all sites but lower reproductive activity and growth. Oysters from Oyster 34 Bay demonstrated greater reproductive activity at all sites with moderate growth and survival. 35 Together these data suggest the existence of O. lurida population structure within Puget Sound 36 and provide information on how broodstock should be selected for restoration purposes.

Knowledge and consideration of these traits should be integrated into conservation efforts. To test for adaptive differences between Olympia oyster populations a reciprocal transplant experiment was carried out monitoring survival, growth, and reproduction using three established populations of Ostrea lurida within Puget Sound, Washington. Performance differed for each population. Ostrea lurida from Dabob Bay had higher survival at all sites but lower reproductive activity and growth. Oysters from Oyster Bay demonstrated greater proportion of brooding females at a majority of sites with moderate growth and survival. Together these data suggest the existence of O. lurida population structure within Puget Sound and provide information on how broodstock should be selected for restoration purposes.

Genetic population structure of Pacific cod, Gadus macrocephalus , was examined across much of its northeastern Pacific range by screening variation at 11 microsatellite DNA loci. Estimates of FST (0.005 ± 0.002) and RST (0.010 ± 0.003) over all samples suggested that effective dispersal is limited among populations. Genetic divergence was highly correlated with geographic distance in an isolation-by-distance (IBD) pattern along the entire coastal continuum in the northeastern Pacific Ocean (~4000 km; r2 = 0.83), extending from Washington State to the Aleutian Islands, and over smaller geographic distances for three locations in Alaska (~1700 km; r2 = 0.56). Slopes of IBD regressions suggested average dispersal distance between birth and reproduction of less than 30 km. Exceptions to this pattern were found in samples taken from fjord environments in the Georgia Basin (the Strait of Georgia (Canada) and Puget Sound (USA)), where populations were differentiated from coastal cod. Our results showed population structure at spatial scales relevant to fisheries management, both caused by limited dispersal along the coast and by sharp barriers to migration isolating smaller stocks in coastal fjord environments.
