Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00428 - 0.01408), b=3.04 (2.87 - 3.21), based on LWR estimates for this species & Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.2 ±0.1 se; Based on diet studies.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (27 of 100) .
