What does F3 give us...
1.) The abundance of adults at a place at a time
2.) The migration of individuals between populations -121.5 -121 -120.5 -120 -119.5 -119 -118.5

We can use this....1.) Increase book keeping - record age, sex and genetic makeup of all fish - larvae and adults
- For the geographers - Categorical data
2.) Investigate the propagation of categorical data through the system by ocean currents

What can we learn...

A Basic evolutionary concept...
1.) Divergence (geographic isolation, genetic drift)
2.) Convergence (migration, mutation)
...We’re testing Genetic Structure driven by ocean currents

A good question to ask...
1.) Is there any structure in the Southern California Bight

Fst Fixation index of the subpopulation compared to the total population (a measure of variance)
=
Fst for the Southern California Bight

1.) If structure - where are the DISCONTINUITIES
2.) The evolution of selective traits
3.) Species Ranges
Other good questions to ask...
