> Siluriformes (Catfishes) > Ictaluridae (North American freshwater catfishes)
Etymology: Noturus: Greek, noton = back + Greek, oura = tail; refred to the position of the tail over the back (Ref. 45335); maydeni: Named for Richard L. Mayden in recognition of his work on species concepts and his contributions to ichthyology, particularly the systematics and biology of central highlands fishes.
Eponymy: Dr Richard Lee Mayden (d: 1955) is an American ichthyologist and systematic biologist. [...] (Ref. 128868), visit book page.

Estimates based on models

Phylogenetic diversity index (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).

Niveau trophique (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

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