“…Maria (although these differences were statistically non-significant after sequential Bonferroni correction). Stockley et al (2005) also suggested some restriction of gene flow for Pagellus bogaraveo between the western islands and the rest of the archipelago, though evidence for this is weak. Genetic approaches may not have sufficient resolution to quantify natal homing unless straying is negligible over evolutionary time scales (Thorrold et al 2001).…”

To estimate connectivity between populations, we used trace-element composition in otoliths of the temperate wrasse Coris julis as a proxy for the environmental conditions experienced from hatch to settlement. Recruits collected at different sites in the Azores archipelago (northeastern Atlantic) differed significantly in their natal chemical signatures, and were sufficiently diverse to be separated into in 4 distinct natal types. Types 1 and 4 were both low in Mg and Ba, although Mg was dominant in Type 1, and Type 4 was more Ba enriched. Type 2 had high Ba and intermediate Mg concentrations, while Type 3 showed the highest Mg and intermediate Ba concentrations. We identified at least 2 natal types present in recruits at each site, which suggests multiple larval sources per site. Recruits from 3 sites did not differ greatly in their natal type composition, suggesting a common set of sources, but also limiting our ability to describe meaningful connectivity and dispersal scenarios. In contrast, we found that the prevalent Natal Type 4 was absent at 1 site, suggesting that the source characterized by Natal Type 4 does not contribute to the replenishment of C. julis populations at the site. The most striking difference was observed at the smallest scale (10s of kilometers), where we found distinct natal type compositions between north and south shores on the same island, suggesting that these 2 sites have consistent differences in the contribution of specific natal sources. Further, the south shore site had recruits with elevated Mg:Ca concentrations from the otolith core to edge, which suggests that these larvae developed in inshore areas and experienced local retention.KEY WORDS: Otolith chemistry · Otolith core · Fish larvae · Trace element · LA-ICP-MS · Dispersal · Population connectivity Resale or republication not permitted without written consent of the publisherMar Ecol Prog Ser 387: [51][52][53][54][55][56][57][58][59] 2009 2003). Fortunately, in some cases, the varying physical and chemical characteristics of ambient seawater are reflected in the larval otolith (structures in the inner ears of fishes composed of a calcium carbonate/protein matrix) and are preserved in its structure, forming a permanent record of past environmental conditions experienced by the individual (Campana & Neilson 1985, Thorrold et al. 1997. Over the past 2 decades several authors have found evidence that larvae growing up in different water masses are likely to produce otoliths of distinct elemental composition (e.g. Swearer et al. 1999, DiBacco & Levin 2000, Thorrold et al. 2001, Forrester & Swearer 2002, Miller & Shanks 2004. Such variations in trace-element compositions of fish otoliths (elemental fingerprints) have been used both to discriminate commercial fish stocks (Campana et al. 1994, Fowler et al. 2005 and to infer migration pathways and environmental conditions experienced by fishes (Thorrold et al. 1997, Jones et al. 1999, Swearer et al. 1999, Secor et al. 2001, Warner et al. 2005, Standish et al. 2008...

“…Studies of mitochondrial DNA markers show that P. bogaraveo exhibits an exceptionally low genetic variability, consistent with the occurrence of a past bottleneck (Bargelloni et al 2003, Stockley et al 2005, Lemos et al 2006, which has been estimated to have happened in the late Pleistocene, a period characterized by strong climate change (Patarnello et al 2007). Stockley et al (2005), however, point out that recent effects of fishing, especially the reduction in the number of females, could also have contributed to the low diversity in the mitochondrial genome.…”

“…Though there seems to be very little genetic variability in this species, possibly due to a past bottleneck (Bargelloni et al 2003, Stockley et al 2005, Patarnello et al 2007, Stockley et al (2005) detected low but significant genetic differentiation in mitochondrial DNA between populations at a regional level, but only between the Azores vs. the mainland and Madeira. The dispersal of benthopelagic fish is limited by the existence of topographical barriers, and the ocean basin that lies between the European continental shelf and the Azores archipelago is likely to constitute a formidable obstacle for P. bogaraveo (Piñera et al 2007), whereas Madeira is closer to the mainland.…”

SUMMARY: In this study the following parasites were selected as biological tags for the identification of blackspot seabream (Pagellus bogaraveo) stocks in the northeast Atlantic: Diphterostomum vividum (Digenea: Zoogonidae), Anisakis simplex s.l., A. physeteris, Anisakis sp. PB-2010 (Nematoda: Anisakidae), and Bolbosoma sp. (Acanthocephala: Polymorphidae). These parasite species point to the existence of three blackspot seabream stocks in the northeast Atlantic: one in the Azores region (ICES Area X), one in continental Portuguese shelf/slope waters (ICES Area IXa), and one in the waters around Madeira (sub-area 1.2 of FAO 34, central-eastern Atlantic).

“…The high haplotype diversity and low nucleotide diversity combination usually suggests a population that had undergone population bottlenecks followed by rapid population growth and accumulation of mutations (Avise et al 1984;Grant & Bowen 1998), which have also been noted in other marine species (Chen et al 2004;Daemen et al 2001;Kong et al 2010;Liu et al 2008;Maggio et al 2009;Pellerito et al 2009;Stockley et al 2005).…”
