“…The widespread occurrence of seaweed, its potential for reflecting passive uptake and its ability to tolerate pollutants makes it a potential alternative biomonitoring organism to blue mussels (Chalkley et al 2019 ). Seaweed has been used for biomonitoring of trace metals via passive uptake routes, however the number of studies investigating the use of seaweed as a biomonitoring organism for PAHs are limited to a few recent studies on green, red, and brown macroalgae (Lourenço et al 2019 ; Pavoni et al 2003 ; Zokm et al 2022 ). Furthermore, these studies have been carried out in the Mediterranean and sub-tropical climate, where the abundance of species, distribution, transport, and degradation of PAHs might differ from that of the Arctic.…”

To evaluate seaweed as a biomonitoring organism, Fucus was sampled in the Faroe Islands. Nineteen PAHs, including the EPA 16, and four groups of alkylated PAHs were quantified using GC–MS analysis of extracts obtained using a modified QuEchERS method with ultrasonication in acetonitrile, back-extraction into hexane, and Florisil® cleanup. Samples from the harbor of Tórshavn collected at high tide were the most polluted with PAH concentrations between 1.3 × 102 and 1.7 × 102 ng/g wet weight. All samples contained a factor 10 higher concentrations of alkylated PAHs compared to their parent compounds. These results suggest that Fucus might be suitable as a biomonitoring organism for PAH pollution. Differences between samples collected in close proximity and on different days were observed (same range of RSD 14–120% and 60–102%, respectively), suggesting that water exchange, tide levels, and direct exposure to surface diesel pollution have a strong influence on pollutant uptake in Fucus. The findings stress the need for further evaluation of the sampling strategy.

This study aimed to evaluate seaweed as a novel biomonitoring organism for polycyclic aromatic hydrocarbon (PAH) pollution in the Faroe Islands. Fucus samples were collected from two cities and two towns. 19 PAHs, including the EPA 16, and four groups of alkylated PAHs, were quantified using GC-MS analysis. PAHs were extracted using a modified QuEchERS method with ultrasonication in acetonitrile, back-extraction into hexane and Florisil® cleanup. Fucus from the harbor of Tórshavn sampled at high tide had the highest PAH concentrations (1.3∙102 to 1.7∙102 ng/g wet weight), with the highest ∑PAH concentrations and abundance of individual PAHs found in Tórshavn, followed by Runavík and Toftir. All samples contained higher concentrations of alkylated PAHs compared to the non-alkylated compounds. The study found that Fucus may be promising as a biomonitoring organism for PAH pollution; however, major differences among samples collected in close proximity and on different days were observed, suggesting that water exchange and tide levels have a strong influence on pollutant uptake in Fucus. Therefore, further evaluation of sampling strategy is necessary. Overall, this study provides important insights into the use of Fucus as a biomonitoring organism for PAH pollution.

“…These small, benthic crustaceans form an important trophic link between primary producers and higher trophic levels [10][11][12], as they are important dietary components for many coastal marine fish species [10]. Furthermore, recent studies have shown the great usefulness of amphipods as marine bioindicators [13][14][15][16][17] and as potential resources in aquaculture [10,[18][19][20][21][22].…”

Despite its importance in intertidal and shallow-water marine ecosystems, Caprella penantis continues to be one of the most taxonomically challenging amphipods in the world. A recent molecular study focusing on C. penantis sensu stricto pointed out the existence of three highly divergent lineages, indicating the possible existence of a process of ongoing speciation and, thus, casting doubt on the taxonomic status of this species. In the present study, we used an integrative approach to continue to shed light on the taxonomy and distribution of this caprellid. To this end, we combined morphological and genetic data (COI and 18S) and included, for the first time, populations from its type locality. Our analyses provide strong evidence of the existence of potentially three distinct species, genetically and geographically restricted, within C. penantis sensu stricto, with the distribution of the true C. penantis sensu stricto restricted to the UK (type locality), the northern coast of the Iberian Peninsula, and the Azores. Results show the co-occurrence of two of these species in a locality of northern Portugal and indicate the existence of distinct evolutionary and diversification patterns along the eastern Atlantic region. Overall, our study highlights the use of an integrative approach to properly assess species boundaries and unravel hidden biodiversity in amphipods.
