Biology     Glossary (e.g. epibenthic)

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00413 - 0.02777), b=2.97 (2.74 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.3 se; Based on size and trophs of closest relatives
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) .
