“Packet Model” Paper Detailed version of PNAS paper –Shows that stochasticity in larval dispersal is set by coastal eddies –Proposes “packet model” –Shows its importance with the “simplest” example (I need your comments on this part)

F3 Model Without Fishing Base case (no stochasticity)

Base Case: No Stochasticity

Stochasticity in Fecundity

Stochasticity in Fecundity & Larval Dispersal

Volume-averaged Adult Density Mean PLD = 30 d Stochasticity in fecundity Stochasticity in fecundity & dispersal Release = 30 d Release = 60 d 10 realizations are used No stochasticity

Stock / Recruitment as a Function of Bin Size (1)

Stock / Recruitment as a Function of Bin Size (2)

Stock / Recruitment as a Function of Bin Size (3)

I am wondering… What I should say about a stock / recruitment relationship –Cannot be fitted by a curve –Even with a larger bin –The role of a bin size on S/R relationship does not seem as expected… it does not approach to a single curve relationship –Any thoughts, Dave?

Stochasticity in fecundity, dispersal & habitat quality
