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 ... -
Anti-hyperglycemic and antioxidant effect of fucoidan extract from Lessonia trabeculata in alloxan-induced diabetes rats
(Springer, 2022-09-30)The objective of this research was to evaluate a nutritional strategy based on the consumption of a fucoidan extract from brown algae Lessonia trabeculata to control oxidative stress in experimental alloxan-induced ... -
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 ... -
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 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?
(Wiley, 2024-03)Saber-tooths, extinct apex predators with long and blade-like upper canines, have appeared iteratively at least five times in the evolutionary history of verte brates. Although saber-tooths exhibit a relatively diverse ... -
Comparison of artificial neural networks and reservoir models for simulating karst spring discharge on five test sites in the Alpine and Mediterranean regions.
(Copernicus Publications (European Geosciences Union), 2023-05-23)Hydrological models are widely used to characterize, understand and manage hydrosystems. Lumped parameter models are of particular interest in karst environments given the complexity and heterogeneity of these systems. ... -
Condensation water in heritage touristic caves: Isotopic and hydrochemical data and a new approach for its quantification through image analysis
(Wiley, 2021)Condensation water is a major factor in the conservation of heritage caves. It can cause dissolution of the rock substrate (and the pigments of rock art drawn on it) or covering thereof with mineral components, depending ... -
