Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00995 (-0.12496 - 0.14487), b=2.91325 (2.82972 - 2.99679), based on LWR estimates for species & family-BS (Ref.
93245).
Trophic Level (Ref.
69278): 3.4 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Moderate vulnerability (37 of 100) .
