Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00661 (0.00400 - 0.01090), b=2.97 (2.82 - 3.12), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (tm=5; tmax=15).
Prior r = 0.42, 2 SD range = 0.21 - 0.87, log(r) = -0.87, SD log(r) = 0.36, Based on: 1 K, 1 tgen, 1 tmax, 3 Fec records
Vulnerability (Ref. 59153):  Low to moderate vulnerability (31 of 100) .
