Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00687 - 0.03186), b=2.97 (2.79 - 3.15), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.4 se; based on size and trophs of closest relatives
Generation time: 1.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (K=1.1; assuming Fec<1000).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (13 of 100) .
Climate Vulnerability (Ref. 125649
): (0 of 100) .
