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=0.00918 (-0.15001 - 0.16837), b=3.08 (2.99 - 3.16), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278): 2.9 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153): Low to moderate vulnerability (32 of 100) .
