Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00393 - 0.02788), b=3.17 (2.94 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.0 ±0.1 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec < 10,000).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (32 of 100) .
