Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00475 - 0.00877), b=3.14 (3.05 - 3.23), in cm Total Length, based on LWR estimates for this species (Ref.
93245).
Trophic Level (Ref.
69278): 3.8 ±0.55 se; Based on food items.
Resilience (Ref.
69278): Low, minimum population doubling time 4.5 - 14 years (Assuming tm>4).
Vulnerability (Ref.
