Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01738 (0.00665 - 0.04544), b=3.01 (2.78 - 3.24), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 4.0 ±0.7 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low to moderate vulnerability (31 of 100) .
