Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00501 (0.00223 - 0.01124), b=3.06 (2.87 - 3.25), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.2 ±0.4 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): Low to moderate vulnerability (30 of 100) .
