Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00955 (0.00441 - 0.02066), b=3.02 (2.84 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.6 ±0.55 se; Based on food items.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Moderate vulnerability (35 of 100) .

Price category (Ref. 80766): Medium.
