Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00878 (-0.18992 - 0.20749), b=2.99 (2.89 - 3.10), based on LWR estimates for this family-BS (Ref.
93245).
Trophic Level (Ref.
69278): 3.6 ±0.55 se; Based on food items.
Resilience (Ref.
69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low to moderate vulnerability (35 of 100) .
