Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00066 (0.00025 - 0.00174), b=3.08 (2.86 - 3.30), based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.4 ±0.45 se; Based on food items.
Resilience (Ref.
69278): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.40; tm=3-4).
Vulnerability (Ref.
59153): Low to moderate vulnerability (35 of 100) .
