Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00541 - 0.02797), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.2 ±0.40 se; based on food items.
Generation time: 2.4 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回复力 (Ref.
