Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5664 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00141 - 0.00976), b=3.11 (2.88 - 3.34), based on LWR estimates for this Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.2 ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (Fec is assumed to be <10).
Vulnerability (Ref. 59153
): Moderate vulnerability (37 of 100) .
