A common framework for the development of spring water contamination early warning system in western Mediterranean karst areas: Spanish and French sites
(Esevier, 2024)Karst water resources, traditionally used worldwide for drinking purposes, are highly vulnerable to contamination. Scientific-technical efforts must therefore be done to ensure sufficient water quality for human consumption. ... -
A Framework to Assess Natural Chloride Background in Coastal Aquifers Affected by Seawater Intrusion in Eastern Spain.
(MDPI, 2023-07-28)The protection of groundwater resources in coastal aquifers is an increasingly important issue worldwide. To establish threshold values and remediation objectives, it is essential to know the natural background concentrations ... -
Aerodynamic modelling of a Cretaceous bird reveals thermal soaring capabilities during early avian evolution
(2017-07)Several flight modes are thought to have evolved during the early evolution of birds. Here, we use a combination of computational modelling and morphofunctional analyses to infer the flight properties of the raven-sized, ... -
An eye for a tooth: Thylacosmilus was not a marsupial ‘‘saber-tooth predator’’
(PeerJ, 2020-06)Background. Saber-toothed mammals, now all extinct, were cats or ‘‘cat-like’’ forms with enlarged, blade-like upper canines, proposed as specialists in taking large prey. During the last 66 Ma, the saber-tooth ecomorph has ... -
Analyzing the causes of method-to-method variability among Rubisco kinetic traits: from the first to the current measurements
(Oxford University Press, 2021)Due to the importance of Rubisco in the biosphere, its kinetic parameters have been measured by different methodologies in a large number of studies over the last 60 years. These parameters are essential to characterize ... -
Application and reassessment of the reduced species list index for macroalgae to assess the ecological status under the Water Framework Directive in the Atlantic coast of Southern Spain
(Elsevier, 2012)According to the Water Framework Directive (WFD) macroalgae are one of the Biological Quality Elements proposed to assess the ecological status of coastal water bodies. In the case of the North East Atlantic coastal shores, ... -
Assessing the influence of isotopic composition of water on that of clay minerals during chemical treatments.
(Elsevier, 2022-03-26)The isotopic composition of hydrogen in authigenic minerals is a useful tool to reconstruct past paleo-environments. Clay minerals are an important component of authigenic minerals in soils and sediments but they usually ... -
Assessment and Characterisation of Ireland’s Green Tides (Ulva Species)
(PLoS, 2017)Enrichment of nutrients and metals in seawater associated with anthropogenic activities can threaten aquatic ecosystems. Consequently, nutrient and metal concentrations are parameters used to define water quality. The ... -
Assessment of a wide array of contaminants of emerging concern in a Mediterranean water basin (Guadalhorce river, Spain): Motivations for an improvement of water management and pollutants surveillance
(Elsevier, 2021-05-19)This study investigates the occurrence and distribution of 185 organic contaminants (regulated pollutants and contaminants of emerging concern; CECs) in surface and groundwater of the Guadalhorce River basin (southern ... -
Biochemical composition of temperate and Arctic populations of Saccharina latissima after exposure to increased pCO2 and temperature reveals ecotypic variation
(Springer, 2014)Previous research suggested that the polar and temperate populations of the kelp Saccharina latissima represent different ecotypes. The ecotypic differentiation might also be reflected in their biochemical composition (BC) ... -
Biomechanical simulations reveal a trade-off between adaptation to glacial climate and dietary niche versatility in European cave bears.
(AAAS, 2020-04-01)The cave bear is one of the best known extinct large mammals that inhabited Europe during the “Ice Age,” becoming extinct ≈24,000 years ago along with other members of the Pleistocene megafauna. Long-standing hypotheses ... -
Biorefinery Approach Applied to the Production of Food Colourants and Biostimulants from Oscillatoria sp
(IOAP-MPDI, 2022-08-22)In this study, a biorefinery based on Oscillatoria sp. is developed to produce high-value compounds such as C-phycocyanin, used in food colourant applications, and biostimulants, used in agriculture-related applications. ... -
Brazilian Beach-Cast Seaweeds: Antioxidant, Photoprotection and Cytotoxicity Properties.
(Springer Nature, 2022-12-15)The potential of seaweed extracts in cosmetic applications have increased with novel development and market. Beneficial biological properties include the ability to struggle aging and anticancer agents. This research aimed ... -
Carbon assimilation in upper subtidal macroalgae is determined by an inverse correlation between Rubisco carboxylation efficiency and CO2 concentrating mechanism effectiveness
(Wiley, 2023)Seaweeds have a wide ecophysiological and phylogenetic diversity with species expressing different Rubisco forms that frequently coexist with biophysical CO2 concentrating mechanisms (CCMs), an adaptation that overcomes ... -
Carbon footprint, economic benefits and sustainable fishing: Lessons for the future from the Western Mediterranean
(Elsevier, 2023)Ensuring an economically viable, sustainable and low CO2 emission extractive fishery is critical in order to achieve sustainable development goals and the climate change commitments. This challenge is even more relevant ... -
Combining Experimental Methods and Modeling to Quantify the Complex Recharge Behavior of Karst Aquifers.
(American Geophysical Union, 2019-01-17)Integration of the abundant information derived from different sources, characterizing techniques and modeling methodologies, is crucial for extending our knowledge of karst aquifers and their available water resources. ... -
Combining hydrodynamics, hydrochemistry, and environmental isotopes to understand the hydrogeological functioning of evaporite-karst springs. An example from southern Spain
(Elsevier, 2019-06-21)This work adopts a multicriteria approach to investigate the functioning of evaporite-karst systems, rarely studied. The natural responses of the main discharge point of the system of study (Lower Anzur spring) were ... -
Combining methane clumped and bulk isotopes, temporal variations in molecular and isotopic composition, and hydrochemical and geological proxies to understand methane's origin in the Ronda peridotite massifs (Spain)
(Elsevier, 2023-10-28)In serpentinised peridotite and ultramafic rock systems, methane (CH4) origin is frequently considered abiotic, but variable microbial and thermogenic components can also exist. Typically, the origin of CH4 is studied using ... -
Comparing cranial biomechanics between Barbourofelis fricki and Smilodon fatalis: Is there a universal killing-bite among saber-toothed predators?
