Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5039 [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 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).
Vulnerability (Ref.
59153): Low to moderate vulnerability (26 of 100) .
