Phylogenetic diversity index (Ref. 82805
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02236 (-0.14208 - 0.18681), b=2.97 (2.88 - 3.06), based on LWR estimates for this family-BS (Ref. 93245
Trophic Level (Ref. 69278
): 2.1 ±0.0 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
