Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00263 (0.00151 - 0.00458), b=3.61 (3.46 - 3.76), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic Level (Ref. 69278): 3.9 ±0.62 se; Based on food items.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm<5).

Vulnerability (Ref. 59153): Moderate to high vulnerability (51 of 100) .

Price category (Ref. 80766): High.
