Eponymy: David [pronounced ‘dahveed’] Acero (d: 2011) was the son of the first author, Arturo Acero. (Ref. 128868), visit book page.

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [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), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.9 ±0.6 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Preliminary low fecundity).

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