Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00291 - 0.01038), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (tmax=1).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
