Biologie     Verklarende woordenlijst (bv. epibenthic)

Affinities: P. pellegrini. Generates electric organ discharge (EOD) of short duration that seems to correlate with aggregative behavior of the species (Ref. 14060; 10601). EOD temporal pattern cues have been shown to play a role in species recognition for P. bovei (Ref. 10600). A ratio measure between olfactory and visual receptor areas suggests that this species relies more on visual than olfactory information (Ref. 10839). A fractional spawner (Ref. 10605; 10606).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.01099 - 0.01901), b=2.86 (2.81 - 2.91), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.3   ±0.0 se; based on diet studies.
Generation time: 2.1 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (K=0.53-1.10; tmax=2.5).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (13 of 100). 🛈
