Tree vigour influences secondary growth but not responsiveness to climatic variability in Holm oak
(Elsevier, 2018)
Many tree species from Mediterranean regions have started to show increased rates of crown defoliation, reduced groth, and dieback associated with the increase in temperatures and changes in the frequency and intensity of ...
Powering newly constructed vessels to comply with ECA regulations under fuel market prices uncertainty: Diesel or dual fuel engine?
(Elsevier, 2019)
Over the last decade, marine engine engineering has evolved considerably, to the point where engine technology can be considered mature and reliable using LNG as fuel without affecting safety at sea. This paper analyses ...
Incorporating non-stomatal limitation improves the performance of leaf and canopy models at high vapour pressure deficit
(Oxford University Press, 2019)
Vapour pressure deficit (D) is projected to increase in the future as temperature rises. In response to increased D, stomatal conductance (gs) and photosynthesis (A) are reduced, which may result in significant reductions ...
Hot-Moments of Soil CO2 Efflux in a Water-Limited Grassland
(MDPI, 2018)
The metabolic activity of water-limited ecosystems is strongly linked to the timing and magnitude of precipitation pulses that can trigger disproportionately high (i.e., hot-moments) ecosystem CO2 fluxes. We analyzed over ...
Habitat fragmentation is linked to cascading effects on soil functioning and CO2 emissions in Mediterranean holm-oak-forests
(PeerJ, 2018)
We studied key mechanisms and drivers of soil functioning by analyzing soil respiration and enzymatic activity in Mediterranean holm oak forest fragments with different influence of the agricultural matrix. For this, ...
Valuing deaths or years of life lost? Economic benefits of avoided mortality from early heat warning systems
(Springer, 2018)
The study aims to explore the main drivers influencing the economic appraisal of heat warning systems by integrating epidemiological modelling and benefit-cost analysis. To shed insights on heat wave mortality valuation, ...
Towards a participatory integrated assessment approach for planning and managing Natura 2000 network sites
(Basque Centre for Climate Change/Klima Aldaketa Ikergai, 2012-10)
Managing protected areas implies dealing with complex social-ecological systems where multiple dimensions (social, institutional, economic and ecological) interact over time for the delivery of ecosystem services. ...
Slip-band distributions and microstructural fading memory beneath the firn ice transition of polar ice sheets
(Elsevier, 2018)
The Antarctic Ice Sheet is a continental ice mass with circa 23 million gigatons of ice, which represent roughly 67 % of world's freshwater supply. This colossal mass of ice is by no means static, as the old ice slowly ...
Physical analysis of an Antarctic ice core-towards an integration of micro-and macrodynamics of polar ice
(Royal Society, 2017)
Microstructures from deep ice cores reflect the dynamic conditions of the drill location as well as the thermodynamic history of the drill site and catchment area in great detail. Ice core parameters (crystal lattice-preferred ...
Estimation of the significance of the Foster's wavelet spectrum by means of the permutation test, and applications to paleoclimate records
(Instituto Geologico y Minero de Espana, 2018)
Here we propose a permutation test-a non-parametric computing-intensive test-to evaluate the statistical significance of the Foster s wavelet spectrum by means of Monte Carlo simulations. A procedure (algorithm) is introduced ...
