Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00733 (-0.12319 - 0.13785), b=3.08 (2.99 - 3.16), based on LWR estimates for species & family-BS (Ref.
93245).
Trophic Level (Ref.
69278): 3.4 ±0.6 se; Based on diet studies.
Resilience (Ref.
69278): Medium, minimum population doubling time 1.4 - 4.4 years (Tmax=4; K=1.85).
Vulnerability (Ref.
59153): Low vulnerability (10 of 100) .
