82805): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00404 (-0.20372 - 0.21179), b=3.14 (3.02 - 3.25), based on LWR estimates for this family-BS (Ref.
93245).
Trophic Level (Ref.
69278): 3.2 ±0.45 se; Based on food items.
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (K=1.20; tmax=3).
Vulnerability (Ref.
59153): Low vulnerability (11 of 100) .
