Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00306 - 0.00988), b=3.04 (2.88 - 3.20), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic Level (Ref.
69278): 3.5 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
