The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These enable users to calculate temporal trends biodiversity within amongst using a broad range of metrics. is being developed as community-led open-source time series. Our goal accelerate facilitate quantitative analysis patterns the Anthropocene.The 8,777,413 abundance records, from consistently sampled for minimum 2 years, which need not necessarily be consecutive. In...
Abstract Mortality during the early stages is a major cause of natural variations in size and recruitment strength marine fish populations. In this study, relation between size-at-hatch survival was assessed using laboratory experiments on field-caught larvae European sardine ( Sardina pilchardus ). Larval not related to egg but significantly, positively diameter otolith-at-hatch. Otolith diameter-at-hatch also significantly correlated with survival-at-age fed unfed laboratory. For collected...
Abstract Current methods for monitoring marine fish (including bony fishes and elasmobranchs) diversity mostly rely on trawling surveys, which are invasive, costly, time‐consuming. Moreover, these selective, targeting a subset of species at the time, can be inaccessible to certain areas. Here, we used environmental DNA (eDNA), present in water column as part shed cells, tissues, or mucus, provide comprehensive information about large area. Further, eDNA results were compared obtained pelagic...
Abstract Restriction‐site‐associated DNA sequencing ( RAD ‐seq) and related methods are revolutionizing the field of population genomics in nonmodel organisms as they allow generating an unprecedented number single nucleotide polymorphisms SNP s) even when no genomic information is available. Yet, ‐seq data analyses rely on assumptions nature variants present a locus, choice which may lead to under‐ or overestimated s and/or incorrectly called genotypes. Using Atlantic mackerel Scomber...
North-east Atlantic mackerel spawning distribution has shifted northward in the last three decades probably response to global sea warming. Yet, uncertainties subsist regarding on shift rate, causalities, and how this species will respond future conditions. Using egg surveys, we explored influence of temperature change mackerel's (western southern components stock) between 1992 2013, projected it may under climate scenarios. We developed generalized additive models: (i) a spatiotemporal...
Abstract Boyra, G., Martínez, U., Cotano, Santos, M., Irigoien, X., and Uriarte, A. 2013. Acoustic surveys for juvenile anchovy in the Bay of Biscay: abundance estimate as an indicator next year's recruitment spatial distribution patterns. – ICES Journal Marine Science, 70: . A series acoustic (JUVENA) began 2003 targeting (Engraulis encrasicolus) Biscay. specific methodology was designed mapping estimating annually, four months after spawning season. After eight years survey, a consistent...
Abstract Multispecies and ecosystem models, which are key for the implementation of ecosystem‐based approaches to fisheries management, require extensive data on trophic interactions between marine organisms, including changes over time. DNA metabarcoding, by allowing simultaneous taxonomic identification community present in hundreds samples, could be used speeding up large‐scale stomach content collection. Yet, metabarcoding routinely implemented, technical challenges should addressed,...
Abstract In this study the spatial distribution of eggs, larvae and juveniles European anchovy ( Engraulis encrasicolus ) was followed in 2004 2005 during three consecutive cruises each year spring–summer to test what limits retention are a non‐upwelling area. Eggs, small large were mainly distributed over shelf, whereas found off shelf. Although overall distributions similar, 2 yr differed that there more coastal individuals 2004, There no significant differences length–weight relationships...
European anchovy larvae were sampled in June 2004 the south-eastern part of Bay Biscay (limits: 4°W, 46°N). Larval distribution was analysed and compared with spawning previous weeks. Patches old found around French Cantabrian shelf (CS) edges even oceanic waters, far from main areas, whereas youngest appeared middle shelf, associated adult locations. The analysis environmental conditions showed significant differences coastal to stations as well areas under influence river discharges. A...
Abstract Various hypotheses have been put forward to explain the mechanisms in Bay of Biscay that result a good recruitment European anchovy. Anchovy larvae from spawning area Gironde River plume are advected towards off‐shelf waters, where juveniles commonly observed. Otolith microstructural and chemical analysis were combined assess importance this transport determine relative contribution these areas for anchovy survival. Chemical otoliths showed can be divided into two groups: group...
Small pelagic fish play a vital role in ecosystems and global fisheries, but their aggregative behavior poses challenges for accurate assessments. While the basic functions of schooling—defense, foraging, mating—are well-documented, dynamics variability these aggregations are less understood. This study analyzes data from JUVENA survey (2013-2020) Bay Biscay, examining 54,240 schools 158 daytime fishing hauls. We analyzed effect local biomass fluctuations, dolphin density, planktivorous...
ABSTRACT Motivation Here, we make available a second version of the BioTIME database, which compiles records abundance estimates for species in sample events ecological assemblages through time. The updated expands 1.0 database by doubling number studies and includes substantial additional curation to taxonomic accuracy records, as well metadata. Moreover, now provide an R package (BioTIMEr) facilitate use database. Main Types Variables Included is composed one main data table containing 11...
Validation of the age determination procedure using otoliths European anchovy in Bay Biscay was achieved by monitoring very strong year-classes successive spring catches and surveys, as well seasonal occurrence edge types. Historical corroboration ageing method obtained cross-correlation between groups surveys (1987–2013). Summary annual growth length is also presented. Yearly annuli consist a hyaline zone (either single or composite) wide opaque zone, disrupted occasionally some typical...
