The effect of long-term atmospheric changes on the macroevolution of birds.
(Elsevier, 2019)Atmospheric conditions are critical for a range of biological functions—locomotion among others—and long-term changes in these conditions have been identified as causal for different macroevolutionary patterns. Here we ... -
Contribution of isotopic research techniques to characterize high-mountain-Mediterranean karst aquifers: The Port del Comte (Eastern Pyrenees) aquifer
(Elsevier, 2019)Water resources in high mountain karst aquifers are usually characterized by high rainfall, recharge and discharge that lead to the sustainability of the downstream ecosystems. Nevertheless, these hydrological systems are ... -
Multi-tracing of recharge seasonality and contamination in groundwater: a tool for urban water resource management
(Elsevier, 2019)In this study, sources of recharge and contamination in urban groundwater and in groundwater un- derneath a forest in the same aquifer were determined and compared. Data on hydro-chemical pa- rameters and stable isotopes ... -
Quantification of methane emissions in a Mediterranean landfill (Southern Spain). A combination of flux chambers and geostatistical methods
(Elsevier, 2019)In this study, landfill gas emissions from a landfill located in southern Spain were estimated using static surface flux chambers and applying and comparing four geostatistical methods; ordinary kriging, lognor- mal kriging, ... -
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 ... -
Methane sources and sinks in karst systems: the Nerja cave and its vadose environment (Spain).
(Elsevier, 2019-08-25)Karst caves are considered a natural sink of atmospheric methane (CH4). Studies generally focus on measuring CH4 within the cave environment, and little information is available about the factors influencing CH4 abundance, ... -
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 ... -
Multi-isotope (δ2H, δ18O, δ13C-TDIC, δ18O-TDIC, 87Sr/86Sr) and hydrochemical study on fractured-karstic and detritic shallow aquifers in the Pampean region, Argentina
(Taylor & Francis, 2020)Fluxes between fractured-karstified and detritic aquifers are commonly poorly understood in many environments. These two types of aquifers are in contact in the southeastern Pampean region in the Argentine Buenos Aires ... -
Coupling air temperature records and gravimetric data to interpret ventilation patterns in a Mediterranean karstic system (Nerja-Pintada caves, southern Spain)
(Elsevier, 2020)Microclimate and geophysical studies are commonly applied to the characterization of karst systems although they are usually used separately. The main purpose of this manuscript is to show how the analysis of the data from ... -
Application of hydrogeochemistry and isotopic characterization for the assessment of recharge in a volcanic aquifer in the eastern region of central Costa Rica.
(Taylor & Francis, 2020)In the eastern region of central Costa Rica, land use in the sub-basins of the Maravilla-Chiz and Quebrada Honda rivers (47 km2) is dominated by agricultural and livestock production, while groundwater resources constitute ... -
Postcranial elements of small mammals as indicators of locomotion and habitat.
(Peer J, 2020)Many studies have shown a correlation between postcranial anatomy and locomotor behavior in mammals, but the postcrania of small mammals (<5 kg) is often considered to be uninformative of their mode of locomotion due to ... -
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 ... -
