Primary results from this work:

NWHI endemic Cellanamelanostomais not a valid species

slide11

Primary results from this work:

NWHI endemic Cellanamelanostomais not a valid species

Management of all 3 species as a single fishery is unfounded

Population structure of each species differs dramatically among islands – each island must be managed separately

slide12

Primary results from this work:

NWHI endemic Cellanamelanostomais not a valid species

Management of all 3 species as a single fishery is unfounded

Population structure of each species differs dramatically among islands – each island must be managed separately

slide13

Primary results from this work:

NWHI endemic Cellanamelanostomais not a valid species

Management of all 3 species as a single fishery is unfounded

Population structure of each species differs dramatically among islands – each island must be managed separately

Use of an exemplar species to represent ecosystems for management or MPA design is highly unreliable

conventional wisdom dispersal distance is positively correlated with pelagic larval duration pld

n = 32, r2 = 0.802 (Siegel et al. 2003)

n = 25, r2 = 0.61 (Shanks et al. 2003)

Conventional wisdom:Dispersal distance is positively correlated with Pelagic Larval Duration (PLD).
