A multidisciplinary approach to the spatial dimension in ecosystem-based fisheries management

Aquatic Living Resources, 2018
This study considers how to reconcile different spatial scales to find the best common denominator to be used as an ecosystem-based management unit. For this, two fishery production zones differing ecologically, economically, legally and institutionally ...

Mixing of porpoise ecotypes in southwestern UK waters revealed by genetic profiling [PDF]

Royal Society Open Science, 2017
Contact zones between ecotypes are windows for understanding how species may react to climate changes. Here, we analysed the fine-scale genetic and morphological variation in harbour porpoises (Phocoena phocoena) around the UK by genotyping 591 stranded ...

Colonisation History of Freshwater Snails Across the Atlantic and Mediterranean Islands: Insights From Mercuria (Littorinimorpha, Hydrobiidae)

Zoologica Scripta, EarlyView.
ABSTRACT Islands harbour unique biodiversity, and depending on their geological origin, they have fundamentally different colonisation histories: continental islands may contain relict faunas shaped by vicariance and sporadic gene flow, whereas oceanic islands must have been colonised across open seas, often through long‐distance dispersal events ...

Stable Isotope–Enabled Particle Drift Models Predict Where High‐Resolution Isotope Analyses Can Discriminate Among Larval Trajectories in Atlantic Mackerel

Fisheries Oceanography, Volume 35, Issue 5, Page 760-776, September 2026.
ABSTRACT Marine fish commonly move across distinct habitats throughout their lifetimes, particularly during larval stages, when they are particularly difficult to track. Such transitions are necessary as environmental demands and predation pressures change dramatically with increases in body size.

Constraints on ship NO_x emissions in Europe using GEOS-Chem and OMI satellite NO₂ observations [PDF]

Atmospheric Chemistry and Physics, 2014
We present a top-down ship NOx emission inventory for the Baltic Sea, the North Sea, the Bay of Biscay and the Mediterranean Sea based on satellite-observed tropospheric NO2 columns of the Ozone Monitoring Instrument (OMI) for 2005–2006.

Temporal Shifts in Subtidal Rocky Benthic Communities Associated With the Invasion of Rugulopteryx okamurae in a Port Environment

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.
ABSTRACT The invasive brown alga Rugulopteryx okamurae, native to the northwestern Pacific, has rapidly expanded along the European Atlantic coast, reaching the Basque Coast in 2023, and was likely already present in 2022. Using annual data from a monitoring survey conducted between 2010 and 2025, this study assesses the spatio‐temporal variability of ...

The influence of rivers on seabird foraging ecology

Biological Reviews, Volume 101, Issue 4, Page 1704-1734, August 2026.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.

Analysis of salinity measurements near islands on the French continental shelf of the Bay of Biscay

Scientia Marina, 2006
The Bay of Biscay is characterised by large fresh water inputs from two major rivers, the Loire and the Gironde, with a mean discharge of about 900 m3/s.

Assessing the Vulnerability and the Stock Status of the Bluntnose Sixgill Shark, Hexanchus griseus, in North‐Eastern Tunisia (Central Mediterranean) Using Data‐Limited Models

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.
ABSTRACT The bluntnose sixgill shark (Hexanchus griseus) is classified as ‘Near Threatened’ at a global level but currently holds a ‘Least Concern’ status in the Mediterranean Sea, despite increasing fishing pressure and insufficient data. This study presents the first comprehensive stock assessment of H. griseus in north‐eastern Tunisia (GFCM GSA 13),
