Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00537 (0.00333 - 0.00866), b=3.11 (2.97 - 3.25), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic Level (Ref. 69278): 3.3 ±0.1 se; Based on diet studies.

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (tm=3-6; tmax=27).

Prior r = 0.37, 2 SD range = 0.19 - 0.72, log(r) = -0.99, SD log(r) = 0.33, Based on: 1 K, 3 tgen, 1 tmax, records

Vulnerability (Ref. 59153): High vulnerability (65 of 100) .

Price category (Ref. 80766): High.
