Discussion

  • Temperature in C for tL_B data for t = 0 at Jan 1: T(t)=13.5+8.5*sin((t+50)*2*pi/365))
  • Temperature in C for tL_E and tL_I data for t = 0 at Jan 1: T(t)=14+3*sin((t+15)*2*pi/365)
  • In view of shrinking in tL data, local food is assumed to follow a year cycle
  • males are assumed to differ from females by {p_Am} only
  • length at death is ignorned due to starvation seasonal starvation periods

Facts

  • This octopus species might survive a first brood and produce a second one, the year after (Ref: StorOcam2010)
  • small eggs with a planktontic larval stage (Ref: Wiki)
  • males mature before females (Ref: StorOcam2010)
