Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00635 - 0.01809), b=3.00 (2.85 - 3.15), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic Level (Ref.
69278): 4.5 ±0.70 se; Based on food items.
Resilience (Ref.
69278): Low, minimum population doubling time 4.5 - 14 years (K=0.04-0.08; tm=4; tmax=11).
Prior r = 0.29, 2 SD range = 0.14 - 0.59, log(r) = -1.24, SD log(r) = 0.36, Based on: 2 K, 1 tgen, 1 tmax, records
