BackgroundThe Mississippi
River Delta is either an upstream or downstream edge for many species
Using modeling, one can know how disasters impact marine life with different dispersal abilities and growth rates

Where should MPAs be placed?

Conclusions Population is most sensitive to disaster at
upstream edge, where it is recruitment limitedMarine life is most sensitive when
mean dispersal distance is highstandard deviation is lowgrowth rate is low
Need further knowledge of species’ dispersal abilities as well as currents to more accurately model the impactof disasters and help withplacement of MPAs
