Assessing changes in size at maturity for the European hake (Merluccius merluccius) in Atlantic Iberian waters

open access: yesScientia Marina, 2022
European hake (Merluccius merluccius) is a commercially important resource in Iberian Atlantic waters. Despite the recovery plan implemented in 2006 and the multiannual management plan for western waters, fishing mortality is still higher than that ...

Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

Tracking the effect of temperature in marine demersal fish communities

open access: yesEcological Indicators, 2021
Under current levels of global warming most demersal species in the Northeast Atlantic are experiencing tropicalization, meridionalization or borealization of their distributions, leading to profound changes in demersal communities.

Low‐intervention clinical trials in Spain: Do they progress?

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Aims Low‐Intervention Clinical Trials (LICTs) are generally pragmatic trials that investigate medicinal products already authorized for use. In 2014, simplified regulatory frameworks were introduced for LICTs with the aim of reducing regulatory burden and operational complexity, to foster non‐commercial clinical trials (NCCTs); the mandatory ...

Seasonal and inter-annual variability of the phytoplankton communities in an upwelling area of the Alborán Sea (SW Mediterranean Sea)

open access: yesScientia Marina, 2005
Temporal variability (seasonal and inter-annual) in the assembly of phytoplankton communities from the northern Alborán Sea was investigated. For this purpose, the taxonomic composition of the micro- and nano-phytoplankton communities at three fixed ...

Dinuclear Rhodium(I)–N‐Heterocyclic Carbene Complexes as Alkyne Hydropyridonation Catalysts

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Catalyst Improvement by NHC tuning: A series of new RhI–NHC dinuclear complexes has been revealed as efficient alkyne hydropyridonation catalysts. 333053IMes complex displays the highest reactivity of the series, suggesting that a moderate steric demand combined with balanced σ‐donation facilitates precatalyst activation and substrate exchange.

Isotopic discrimination factors and nitrogen turnover rates in reared Atlantic bluefin tuna larvae (Thunnus thynnus): effects of maternal transmission

open access: yesScientia Marina, 2016
The use of stable isotope analysis to study animal diets requires estimates of isotopic turnover rates (half time, t50) and discrimination factors (Δ) for an accurate interpretation of trophic patterns.

Gender Mainstreaming in Urban Food Policies: Governance Processes and Policy Designs From Three Spanish Cities

open access: yesEuropean Policy Analysis, EarlyView.
ABSTRACT This paper explores the integration of gender mainstreaming in urban food policies (UFPs) through three Spanish case studies: Barcelona, Valencia, and Zaragoza. While UFPs are pivotal for addressing sustainability in urban food systems, attention to gender disparities within them remains insufficient.
