Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00321 - 0.01560), b=3.09 (2.91 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.5   ±0.1 se; Based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 69278):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (tmax=3).
Verwundbarkeit (Ref. 59153):  Low vulnerability (17 of 100) .
