Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.00696 - 0.02076), b=3.01 (2.86 - 3.16), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.4 ±0.3 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.
59153): Low to moderate vulnerability (29 of 100) .
