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=0.00977 (0.00446 - 0.02143), b=3.23 (3.05 - 3.41), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 2.9 ±0.4 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 vulnerability (20 of 100) .
