Etymology: Lamprologus: Greek, lampros = light + Greek, lagos = hare (Ref. 45335); markerti: This species is named for Jeffrey Markert whose initial analyses of cichlid population structure in the region of the large Inga Rapids stimulated the morphological study of this species (Ref. 97099).

Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 16 - 18; Dorsale zachte stralen (totaal) : 7 - 8; Anale stekels: 4 - 6; Anale zachte stralen: 5 - 7; Wervels: 32 - 33. Diagnosis: Lamprologus markerti is readily distinguished from L. tigripictilis by the presence of 4-6 broad dark bars on the flanks vs. 7-10 narrow bars, and from L. werneri in the possession of 14 vs. 15 precaudal vertebrae (Ref. 97099). It differs from both L. tigripictilis and L. werneri in a reduced number of gill rakers on the first arch, 9-10 vs. 12-17; a longer head, 32.1-34.7% of standard length vs. 29.3-31.9 and 29.1-32.9% respectively; and a longer predorsal length, 33.0-35.9% of standard length vs. 29.3-32.7 and 28.5-32.6% respectively (Ref. 97099). Further, L. markerti lacks an intestinal loop present in both L. tigripictilis and L. werneri, and has a highly reduced infraorbital series often consisting only of the first infraorbital element (Ref. 97099).

This species appears to be a habitat generalist found over a range of substrates from marginal riffle and rocks near rapids, to stiller water habitats over sand and mud (Ref. 97099).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), 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): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
