Estimates based on models

Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00049 (0.00022 - 0.00111), b=3.10 (2.91 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  3.3   ±0.40 se; Based on food items. Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.). Vulnerability (Ref. 59153 ):  Moderate vulnerability (38 of 100) .
