Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00372 - 0.01120), b=3.22 (3.07 - 3.37), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic Level (Ref.
69278): 3.3 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 41,650-86580).
Vulnerability (Ref.
