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 ... -
Sixty-six million years along the road of mammalian ecomorphological specialization.
(Proceedings of the National Academy of Sciences of the United States, 2019-06-25)The fossil record of the large terrestrial mammals of the NorthAmerican Cenozoic has previously been quantitatively summarizedin six sequential episodes of faunal associations—“evolutionary faunas”—that correspond well ... -
Phenotypic integration and modularity drives skull shape divergence in the Arctic fox (Vulpes lagopus) from the Commander Islands
(Royal Society, 2019-09-25)Phenotypic integration and modularity influence morphological disparity and evolvability. However, studies addressing how morphological integration and modularity change for long periods of genetic isolation are scarce. ... -
Geochemistry and mineralogy of serpentinization-driven hyperalkaline springs in the Ronda peridotites.
(Elsevier, 2019-12-15)We present a detailed study of the water geochemistry, mineralogy and textures in serpentinization- related hyperalkaline springs in the Ronda peridotites. Ronda waters can be classified into hyperalka- line fluids and ... -
Groundwater dating tools (3H, 3He, 4He, CFC-12, SF6) coupled with hydrochemistry to evaluate the hydrogeological functioning of complex evaporite-karst settings.
(Elsevier, 2020)The hydrogeological functioning of four different areas in a complex evaporite-karst unit of predominantly aquitard behavior in S Spain was investigated. Environmental dating tracers (3H, 3He, 4He, CFC-12, SF6) and ... -
Complimentary use of dating and hydrochemical tools to assess mixing processes involving centenarian groundwater in a geologically complex alpine karst aquifer.
(Wiley, 2020)Environmental dating tracers (3H, 3He, 4He, CFC-12, CFC-11, SF6) and the natural spring response (hydrochemistry, water temperature, and hydrodynamics) were jointly used to assess mixing processes and to characterize ... -
Evolutionary trends in RuBisCO kinetics and their co-evolution with CO2 concentrating mechanisms
(Wiley, 2020)RuBisCO-catalyzed CO2 fixation is the main source of organic carbon in the biosphere. This enzyme is present in all domains of life in different forms (III, II, and I) and its origin goes back to 3500 Mya, when the atmosphere ... -
Hydro-environmental changes assessment after Guadalhorce River mouth channelization. An example of hydromodification in southern Spain
(Elsevier, 2020-02-01)The Guadalhorce River mouth (Málaga, Southern Spain) was channelized between 1997 and 2003 to reduce flooding potential in adjacent densely populated sections of Málaga. The channel was bifurcated near the Mediterranean ... -
Global karst springs hydrograph dataset for research and management of the world’s fastest-flowing groundwater.
(Nature, 2020-02-20)Tunde et al. (2020) presentan los resultados de un laborioso trabajo de recopilación de series temporales de datos de caudal de más de 400 manantiales de naturaleza kárstica de todo el mundo. Los hidrogramas se han obtenido ... -
Modelling the effects of climate change and population growth in four intensively exploited Mediterranean aquifers. The Mijas range, Southern Spain.
(Elsevier, 2020-03)Groundwater is key to economic growth in the Mediterranean region. This is particularly true of areas such as southern Spain, where aquifers underpin social development by supplying water to a booming tourist industry. ... -
Developmental constraints do not influence long-term phenotypic evolution of marsupial forelimbs as revealed by interspecific disparity and integration patterns.
(The University of Chicago Press, 2020-03-03)Marsupials show a smaller range of forelimb ecomorphologies than placental mammals, and it is hypothesized that this results from macroevolutionary constraints imposed by the specialized reproductive biology of marsupials. ... -
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 ... -
Morphological Disparity of the Humerus in Modern Birds
(MDPI, 2020-05)From a functional standpoint, the humerus is a key element in the skeleton of vertebrates as it is the forelimb's bone that connects with the pectoral girdle. In most birds, the humerus receives both the forces exerted by ... -
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 ... -
Laser-stimulated fluorescence refines flight modeling of the early cretaceous bird sapeornis.
(American Museum of Natural History, 2020-08-21)Unseen and difficult-to-see soft tissues of fossil birds revealed by laser-stimulated fluorescence (LSF) shed light on their functional morphology. Here we study a well-preserved specimen of the early pygostylian Sapeornis ... -
Morphological convergence obscures functional diversity in sabre-toothed carnivores
(Royal Society, 2020-09-30)The acquisition of elongated, sabre-like canines in multiple vertebrate cladesduring the last 265 Myr represents a remarkable example for convergentevolution. Due to striking superficial similarities in the cranial ... -
