Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00602 - 0.02092), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.39 se; based on food items.
Generation time: 3.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (tmax=11).
Vulnerability (Ref. 59153
): Moderate vulnerability (39 of 100) .
