Synergistic Enhancement of Antioxidant Activity in Arbutus unedo Leaf Extract by Biological Fluids: Implications for Functional and Nutraceutical Applications

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT This study examined the effect of biological fluids (saliva, blood plasma, and urine) on the antioxidant capacity of an aqueous extract derived from Arbutus unedo leaves. The extract displayed a concentration‐dependent reducing activity in the ferric reducing power assay (IC50 = 292 ± 7.54 µg/mL) and phosphomolybdenum assays (IC50 = 461.67 ± 4.

A statistical approach to unveil phytoplankton adaptation to ocean fronts [PDF]

open access: yesAdvances in Statistical Climatology, Meteorology and Oceanography
Fine-scale oceanic fronts are ubiquitous and ephemeral physical features that separate contrasting water masses, creating significant heterogeneity in the physical seascape and plankton distributions.

Neodymium isotopic composition and concentration in the western North Atlantic Ocean: results from the GEOTRACES GA02 section [PDF]

open access: yes, 2015
The neodymium (Nd) isotopic composition of seawater is commonly used as a proxy to study past changes in the thermohaline circulation. The modern database for such reconstructions is however poor and the understanding of the underlying processes is ...

Ocean Circulation And Water Masses Distribution In Seamounts In The Path Of The Mediterranean Outflow Waters

open access: yes, 2017
The objective of the physical oceanography contribution during the cruise was to determine if the vertical water mass distribution and specifically the Mediterranean Outflow Waters (MOW) affects the vertical distribution of cold-water corals on the slopes of the seamounts.

The influence of rivers on seabird foraging ecology

open access: yesBiological Reviews, EarlyView.
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 ...

Evaporites and the salinity of the ocean during the Phanerozoic: Implications for climate, ocean circulation and life [PDF]

open access: yes, 2005
A compilation of data on volumes and masses of evaporite deposits is used as the basis for reconstruction of the salinity of the ocean in the past.

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife

open access: yesBiological Reviews, EarlyView.
ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over

Hydrographic vs. Dynamic Description of a Basin: The Example of Baroclinic Motion in the Ionian Sea

open access: yesOceans
The Ionian Sea is a crucial intersection for various water masses in the Mediterranean. Its hydrography and dynamics play a significant role in the seawater budgets and biogeochemistry of the neighboring sub-basins. Multiple theories have been formulated

Temporal changes in the water mass distribution and transports along the 20ºW CAIBOX section (NE Atlantic)

open access: yesCiencias Marinas, 2011
The CAIBOX cruise was conducted from 25 July to 14 August 2009. Three consecutive transects (zonal, meridional, and transverse) formed a closed box to the west of the Strait of Gibraltar.
