Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00264 - 0.01091), b=3.22 (3.05 - 3.39), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.6   ±0.40 se; based on food items.
Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resiliens (Ref. 120179):  Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (K=0.65; tm=3-4; tmax=10).
Vulnerability (Ref. 59153):  Low vulnerability (23 of 100) .
