Metabarcoding (large-scale taxonomic identification of complex samples via analysis one or few orthologous DNA regions, called barcodes) is revolutionizing biodiversity marine zooplankton assemblages. relies on high-throughput sequencing (HTS) technologies, which yield millions sequences in parallel and allow large-scale environmental samples. studies have used various regions nuclear small- (18S) large-subunit (28S) rRNA, accurate classification novel reliable amplification with consensus...
This article documents the addition of 139 microsatellite marker loci and 90 pairs single-nucleotide polymorphism sequencing primers to Molecular Ecology Resources Database. Loci were developed for following species: Aglaoctenus lagotis, Costus pulverulentus, scaber, Culex pipiens, Dascyllus marginatus, Lupinus nanus Benth, Phloeomyzus passerini, Podarcis muralis, Rhododendron rubropilosum Hayata var. taiwanalpinum Zoarces viviparus. These cross-tested on quinquefasciatus, pseudochrysanthum...
Abstract The potential of the 18S rRNA V9 metabarcoding approach for diet assessment was explored using MiSeq paired‐end (PE; 2 × 150 bp) technology. To critically evaluate method′s performance with degraded/digested DNA, diets two zooplanktivorous fish species from Bay Biscay, European sardine ( Sardina pilchardus ) and sprat Sprattus sprattus ), were analysed. taxonomic resolution quantitative first assessed both in silico mock field plankton samples. Our method capable discriminating...
The objective of this study was to investigate whether successive recruitment failures in the anchovy fishery Bay Biscay were due changes zooplankton biomass or composition. Image analysis and automatic recognition used analyse samples collected during diel egg production method spring surveys from 1998 2006. We not able detect any trend period. spatial distribution showed permanent features with large organisms being more abundant over shelf break outer areas. Finally, we found a negative...
Geographic surveys of allozymes, microsatellites, nuclear DNA (nDNA) and mitochondrial (mtDNA) have detected several genetic subdivisions among European anchovy populations. However, these studies been limited in their power to detect some aspects population structure by the use a single or few molecular markers, geographic sampling. We multi-marker approach, 47 nDNA 15 mtDNA nucleotide polymorphisms (SNPs), analyze 626 anchovies from whole range species resolve shallow deep levels...
Abstract The Atlantic bluefin tuna is a highly migratory species emblematic of the challenges associated with shared fisheries management. In an effort to resolve species’ stock dynamics, genomewide search for spatially informative single nucleotide polymorphisms ( SNP s) was undertaken, by way sequencing reduced representation libraries. An allele frequency approach discovery used, combining data 555 larvae and young‐of‐the‐year LYOY ) into pools representing major geographical areas...
Summary The optimal management of the commercially important, but mostly over‐exploited, pelagic tunas, albacore ( Thunnus alalunga Bonn., 1788) and Atlantic bluefin tuna BFT ; thynnus L., 1758), requires a better understanding population structure than has been provided by previous molecular methods. Despite numerous studies both species, their structures remain controversial. This study reports development single nucleotide polymorphisms SNP s) in application these s to survey genetic...
Increased throughput in sequencing technologies has facilitated the acquisition of detailed genomic information non-model species. The focus this research was to discover and validate SNPs derived from European anchovy (Engraulis encrasicolus) transcriptome, a species with no available reference genome, using next generation technologies. A cDNA library constructed four tissues ten fish individuals corresponding three populations E. encrasicolus, Roche 454 GS FLX Titanium yielded 19,367...
In this study, 16S rRNA gene sequencing was used to characterize the changes in taxonomic composition and environmental factors significantly influencing bacterial community structure across an annual cycle Estuary of Bilbao as well its tributaries. spite estuary being small characterized by a short residence time, most highly correlated with mirrored those reported govern larger estuaries, specifically salinity temperature. Additionally, appeared vary precipitation. For example, increase...

This study is a part of the zooplankton monitoring program carried out in euhaline region estuaries Bilbao and Urdaibai (Basque coast, Bay Biscay), analyses between-estuaries differences spatial temporal patterns relation to environmental conditions between July 1999 May 2001. Environmental variables measured were water temperature, dissolved oxygen saturation (DOS), Secchi disk depth (SDD) chlorophyll a. Relationships community analysed using canonical correspondence analysis; distribution...
A fine scale spatial resolution survey (3 × 15 nautical miles) was conducted during May 2004 in the Bay of Biscay (43.32–46.12°N and 1.29–4.31°W), to study zooplankton community onset spring stratification. Cluster analysis classified 45 most abundant taxa into seven major groups. In southern part surveyed area, a front separating neritic waters from eddies off shelf delimited distinct communities. On northern side river plumes generation internal waves over break were main mesoscale...

With increasing attention on green(ing) cities, urban nature is used to increase liveability, create new sectors such as tourism, and boost international investment. What counts desirable green intervention generally follows internationally accepted practices cities aim for recognition. Here, we examine the historic production of a identity ways in which leaders have navigated local politics enact greening.

We analyze a multi-level ad-hoc emergency fund (MAEF) – the European NextGenerationEU program as an opportunity to advance ambitious municipal climate action. Presently, MAEF follow vertical complex governance structure, including strict timelines, evaluations, and competencies spread across policy scales, which condition local aspirations for transformative in terms of participation, inclusion, equity. Drawing on qualitative data (interviews with key actors, participant observations,...
In this study, we analysed the factors explaining distribution and betadiversity of mesozooplankton species in shelf coastal areas Bay Biscay. Nonparametric multiplicative regression models showed that for 35% 26 analysed, geographical position was main factor distribution. The variation partitioning results analysis indicate niche adaptation (12–25%) dispersal limitation (14–15%) influence equally. Therefore, most variance (57–66%) remains unexplained suggesting there are other not...
