Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.7 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): High vulnerability (58 of 100) .
