From: Identifying the key biophysical drivers, connectivity outcomes, and metapopulation consequences of larval dispersal in the sea

Parameter Description Value range
RO Reproductive output (larvae) per unit area [100, 10,000]
A Daily larval mortality (Weibull rate parameter) [0.01, 0.50]
B Daily larval mortality (Weibull shape parameter) [0.50, 1.0]
PreP Proportion of maxPLD required for competency [0.05, 0.95]
ComR Rate of transition to being competent for settlement [0.05, 0.50]
DevP Initial relative developmental time as passive w/initFV [0.05, 0.95]
iFV Fall velocity during DevT (ms−1, positive up) [−0.001, 0.001]
K Diffusivity, or the biological-physical repulsion among larvae (m2s−1) [0.01, 1.00]
Behav Vertical behaviour strategy: Passive, Benthic-seeking (1), or Diel migration (2). [0, 1, 2]
Sp Behaviour parameter: Swimming capacity Vertical swim speed is scaled at 5 % of this. (ms−1) [0.001, 0.100]
TD Behaviour parameter: Target depth (m) [0.5, 20.0]
HmD Behaviour parameter: Habitat detect distance (km) [0, 2, 4, 6, 8, 10]
PLD Maximum duration of larval stage (days) [1, 50]
Sr Post-settlement survival prior to recruitment [0, 1]
rf Unique reefs within PPB system (ID) [3, 10, 12, 16, 18, 23, 26, 32]
rls Date of larval release [July1 2009, October 1 2009, & January 1 2010]
  1. Intrinsic parameter value ranges were chosen to be as broad as possible, but still biologically realistic, in order to capture most of potential variability in early life histories among benthic marine organisms. Reefs and larval release dates were chosen to capture the full range of geographical and temporal variability in local oceanography
