Brown trout phylogenetics: A persistent mirage towards (too) many species

Abstract

Funding informationM. Oral was supported by a visiting grant from the MUSE "Explore" programme, publicly funded through the ANR (French National Research Agency) under the "Investissements d'avenir" program (ANR-16-IDEX-0006) and the Erasmus+ program of the European Union."… such abundant literature and insightful studies may be little more than a mirage".

Phenotypic Variation in Brook Trout Salvelinus fontinalis (Mitchill) at Broad Spatial Scales Makes Morphology an Insufficient Basis for Taxonomic Reclassification of the Species

“…Phylogenetic uncertainty stemming from vast intraspecific variation is not unique to the discussion of Brook Trout taxonomy and has long been part of conversations related to the conservation of Salvelinus and other stream salmonids (Guinand et al, 2021). Repeated radiation through increasingly diverse environments has led to significant uncertainty in how to appropriately classify the extensive taxonomic and functional diversity in many species of Salvelinus (Reist et al, 2013).…”

“…Furthermore, several species concepts with no consensus decision has resulted in inflated taxonomic identifications (23 species according to IUCN, 2020; 30-35 species according to Kottelat & Freyhof, 2007;Sanz, 2018 andup to 60 species according to Behnke, 1986;Jonsson & Jonsson, 2011;Froese & Pauly, 2019). However, the most recent opinion paper by Guinand, Oral & Tougard, (2021), discussed thoroughly that phenotypic and genotypic diversity of brown trout is best explained in the concept of species complex and indicates multiple trout species.…”

“…However, salmon taxonomy is still confusing and problematic. In recent years, there are lots of studies about biogeography, phylogeny, phylogeographic and systematic position of Salmo species (Bardakci et al, 2006;Sušnik et al, 2006;Kanjuh et al, 2020;Guinand et al, 2021). Rossi et al (2019) investigated the genetic identification of native populations of S. trutta complex in central Italy and found that most of the haplotypes observed belong to the Adriatic or Mediterranean lineages.…”

“…However, reported 14 Salmo species from the inland waters of Turkey. Guinand et al (2021) indicated that the delimitation of trout taxa by ichthyologists was certainly first impacted by the poor awareness of phenotypic plasticity and speciation as a process, then based on species concepts based on diagnosability, while these taxa are not reproductively isolated and contradict Mayr's (1942) biological species concept.…”
