Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.1 ±0.1 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): High vulnerability (58 of 100) .
