Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00462 - 0.01365), b=3.11 (2.96 - 3.26), based on LWR estimates for species & (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.0 ±0.00 se; Based on food items.
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (34 of 100) .
