Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00933 (0.00498 - 0.01748), b=3.07 (2.91 - 3.23), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisk nivå (Ref. 69278): 2.9 ±0.28 se; Based on food items.

Resiliens (Ref. 69278): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100) .

Price category (Ref. 80766): Very high.
