Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01363 (-0.01277 - 0.04002), b=2.91 (2.89 - 2.93), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278): 4.4 ±0.8 se; Based on diet studies.
Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.13(?)-0.35;).
Vulnerability (Ref. 59153): Moderate vulnerability (36 of 100) .
