Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00563 (-0.22542 - 0.23668), b=3.13 (3.01 - 3.26), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278): 3.1 ±0.32 se; Based on food items.
Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Tmax < 1 year.).
Vulnerability (Ref. 59153): Low vulnerability (10 of 100) .
