“…Although this study did not control for morphotypes, and this is still an ongoing subject of research, results obtained in [32] using the same genetic markers point to the conclusion that our results are not affected by it.…”

Historical gene flow constraints in a northeastern Atlantic fish: phylogeography of the ballan wrasseLabrus bergyltaacross its distribution range

et al. 2017

The distribution and demographic patterns of marine organisms in the north Atlantic were largely shaped by climatic changes during the Pleistocene, when recurrent glacial maxima forced them to move south or to survive in northern peri-glacial refugia. These patterns were also influenced by biological and ecological factors intrinsic to each species, namely their dispersion ability. The ballan wrasse (Labrus bergylta), the largest labrid fish along Europe's continental margins, is a target for fisheries and aquaculture industry. The phylogeographic pattern, population structure, potential glacial refugia and recolonization routes for this species were assessed across its full distribution range, using mitochondrial and nuclear markers. The existence of a marked population structure can reflect both recolonization from three distinct glacial refugia and current and past oceanographic circulation patterns. Although isolated in present times, shared haplotypes between continental and Azores populations and historical exchange of migrants in both directions point to a common origin of L. bergylta. This situation is likely to be maintained and/or accentuated by current circulation patterns in the north Atlantic, and may lead to incipient speciation in the already distinct Azorean population. Future monitoring of this species is crucial to evaluate how this species is coping with current environmental changes.

“…In all cases, population trends by species obtained from different sources were normalized to the interview-derived scale (from −2 to 2). The two morphotypes of ballan wrasse Labrus bergylta (Ascanius, 1767; Almada et al, 2016;Quintela et al, 2016), pinto (spotted and reddish) and maragota (plain greenish or brown) (sensu Villegas-Ríos et al, 2013) were treated separately when possible.…”

“…Since it has been suggested that there are two morphotypes of L. bergylta (Almada et al , 2016; Quintela et al , 2016), that differ in their colour (i.e. ‘Pinto’, a spotted and reddish form, and ‘Maragota’, plain greenish or brown; Villegas-Ríos et al , 2013), they were treated separately in this paper.…”

Although necessary for sustainable management of coastal ecosystems the understanding of trophic ecology of kelp fishes remains largely limited in the NE Atlantic. In this paper, stable isotope ratios of carbon (C) and nitrogen (N), complementarily with analyses of stomach contents, were used to investigate the trophic ecology of an Atlantic kelp forest fish assemblage targeted by spear fishers in Galicia (NW Spain). Trophic habits of the fishes were consistent across the species ranges and six trophic niches were identified. Chelon labrosus was the only pelagic omnivore, while Conger conger and Dicentrarchus labrax were the principal predators, preying on benthic osteichthyes. The intermediate carnivorous Diplodus sargus mainly preyed on benthic molluscs, while Labrus bergylta exploited a wider range of prey. Although associated with different trophic niches, the two morphotypes of L. bergylta showed some degree of diet overlap, providing little support to the hypothesis of their separate management. Moreover, L. bergylta can be a keystone species whose adequate management has relevant implications for the sustainable use of the European kelp forest ecosystems.

On the absence of genetic differentiation between morphotypes of the ballan wrasse Labrus bergylta (Labridae)

Abstract: The ballan wrasse, Labrus bergylta (Labridae), is a protogynous hermaphrodite fish common in the northeastern Atlantic from Norway to Morocco. It is a commercially important resource for local fisheries and is currently being used as cleaner fish to control sea lice in salmon 1,*
