50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00919 (-0.18912 - 0.20751), b=3.06 (2.95 - 3.17), based on LWR estimates for species & family-BS (Ref.
93245).
Trophic Level (Ref.
69278): 3.9 ±0.63 se; Based on food items.
Resilience (Ref.
69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Moderate to high vulnerability (46 of 100) .
