Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00552 - 0.02177), b=2.99 (2.80 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 2.3 ±0.1 se; based on size and trophs of closest relatives
Generation time: 4.0 ( 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 (tm=2; k=0.27; Tmax=7).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (34 of 100) .
