Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00307 - 0.00746), b=3.25 (3.12 - 3.38), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.3 ±0.2 se; based on diet studies.
Generation time: 3.9 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=10; K=0.28; Fec=33,300).
Vulnerability (Ref. 59153
): Moderate vulnerability (42 of 100) .
