Abstract Zooplankton phenological shifts may affect energy transfer through pelagic food web and up to fisheries, but few studies have compared zooplankton phenology across a wide latitudinal range of water temperatures. We examined the variations at four sites along gradient from Bay Biscay [Bilbao Urdaibai (BU)], English Channel (Plymouth; L4), North Sea [Stonehaven (SH)] 1999 2013. taxa showed interannual that were opposite in direction between southernmost BU northernmost SH sites. The East Atlantic pattern was climate teleconnection best related variations. Among local variables , salinity changes as opposed those SH. Locally, chlorophyll most relevant temperature L4. While we did see some imprints causing expected directions shifts, i.e. towards earlier appearance spring later autumn warm years, these patterns by no means clear-cut. dominant role driving variation suggested seems be obscured biotic climatic controls acting differently our environmental gradient.

For coarse groups latitude explained main between-site differences, meroplankton contributed more than holoplankton. Latitudinal differences best indicated contrasting abundances cirripede larvae doliolids (most abundant at lowest sites) bryozoan polychaete highest site). Doliolids indicators temperature-mediated latitudinal differences.

Sixteen years (2005–2020) of zooplankton monitoring in the Bay Marseille (N-W Mediterranean Sea) are analyzed relation to physical, meteorological, climatic and biotic data. Samples were collected every two weeks by a vertical haul (0–55 m) 200 μm plankton net. Different indices characterizing mesozooplankton compared: biomass dry weight four size fractions between 2000 μm; abundances whole 13 main taxonomic groups defined from imagery; seasonal onset timing each group; other types indices: first characterized diversity based on abundance data, second was derived spectra shape. The clearest pattern environmental compartment an overall decreasing trend nutrients, shifts phytoplankton metrics (i.e. structure particulate organic matter), changes winter conditions increasing temperatures, precipitation NAO).

This study describes the phytoplankton community in sheltered euhaline waters of Basque coast (southeastern Bay Biscay). Phytoplankton composition, cell size, abundance, biomass and presence potentially toxic taxa, together with chlorophyll a, nutrients hydrographic optical conditions were measured, from August 2016 to 2017, Mutriku port, main aim assessing suitability as a food resource for bivalves. The water column showed typical environmental marine waters, no significant nutrient enrichment caused by anthropogenic pressures. Haptophytes represented greatest contribution abundance (31–47%), diatoms dominant group terms (52–79%), which could favour mussel growth due their high fatty acid content. In addition, size structure was suitable ingestion, since predominant 2–20 µm. Regarding phytoplankton, genera that pose risk human health those affect negatively physiology survival considered. Altogether, ten taxa identified, contributing less than 5% total Mutriku. However, median concentration low (0.5 µg L−1), reflecting oligotrophic area. Therefore, even if composition be favourable bivalve aquaculture, values are compared other zones production.

Cetaceans adjust their distribution and abundance to encountered conditions across years seasons, but we poorly understand such small-scale changes for many species, especially in winter. Crucial challenges confront some populations during this season, as the high levels of fisheries-induced mortality faced by common dolphin ( Delphinus delphis ) Northeast Atlantic shelves. For understanding winter fine-scale dynamics is crucial. We aimed identify drivers winters 2020 2021, with a focus on determining lag between oceanographic distribution.
