Scarce population genetic differentiation but substantial spatiotemporal phenotypic variation of water‑use efficiency in Pinus sylvestris at its western distribution range
(Springer, 2018-10-23)Water and carbon fluxes in forests are largely related to leaf gas exchange physiology varying across spatiotemporal scales and modulated by plant responses to environmental cues. We quantified the relevance of genetic and ... -
Phenotypic plasticity and climatic adaptation in an Atlantic maritime pine breeding population
(Springer Verlag, 2012)Context: Pinus pinaster Ait. is found in the Iberian Peninsula under Mediterranean and Atlantic conditions. Both climates encounter each other in Galicia (NW Spain), where two bioclimatic regions can be differentiated: ... -
DendroSync: An R package to unravel synchrony patterns in tree-ring networks
(Elsevier, 2017-12-15)Spatial synchrony refers to the presence of a common signal for a time-varying characteristic that, in dendrosciences, is shared among tree-ring chronologies from a particular area. Analysis and interpretation of synchrony ... -
Intraspecific variation in the use of water sources by the circum-Mediterranean conifer Pinus halepensis
(Wiley, 2015-07-21)Summary The relevance of interspecific variation in the use of plant water sources has been recognized in drought-prone environments. By contrast, the characterization of intraspecific differences in water uptake patterns ... -
A roadmap to disentangling ecogeographical patterns of spatial synchrony in dendrosciences
(Springer Verlag, 2017-12-30)The concept of spatial synchrony in ecology refers to the presence of coordinated time fluctuations in certain characteristics that can be observed in plant and animal communities inhabiting an area. It is a well-known ... -
Ecotypic variation and stability in growth performance of the thermophilic conifer Pinus halepensis across the Mediterranean basin
(Elsevier, 2018)The combined effects of local adaptation and phenotypic plasticity influencing plant performance are relevant to understand the capacity for genetic responses to climate change. Pinus halepensis is a native species of low- ... -
Minimum wood density of conifers portrays changes in early season precipitation at dry and cold Eurasian regions
(Springer, 2017-05-03)Tracheids fulfil most wood functions in conifers (mechanical support and water transport) and earlywood tracheids account for most hydraulic conductivity within the annual tree ring. Dry conditions during the early growing ... -
Aged but withstanding: Maintenance of growth rates in old pines is not related to enhanced water-use efficiency
(Elsevier, 2017-05-03)Growth of old trees in cold-limited forests may benefit from recent climate warming and rising atmospheric CO2 concentrations (ca) if age-related constraints do not impair wood formation. To test this hypothesis, we studied ... -
Interpreting genotype-by-environment interaction for biomass production in hybrid poplars under short-rotation coppice in Mediterranean environments
(John Wiley & Sons Ltd., 2016-11-01)Understanding genotype × environment interaction (GEI) is crucial to optimize the deployment of clonal material to field conditions in short‐rotation coppice poplar plantations. Hybrid poplars are grown for biomass production ... -
Unravelling spatiotemporal tree-ring signals in Mediterranean oaks: a variance¿covariance modelling approach of carbon and oxygen isotope ratios
(Oxford University Press, 2014)Identifying how physiological responses are structured across environmental gradients is critical to understanding in what manner ecological factors determine tree performance. Here, we investigated the spatiotemporal ... -
Carbon isotope discrimination, radial growth, and NDVI share spatiotemporal responses to precipitation in Aleppo pine
(Springer, 2015)The aim of this study was to assess the spatiotemporal variability of carbon isotope discrimination (Δ13C) records and its relationship with radial growth (RG) and Normalized Difference Vegetation Index (NDVI) data using ... -
Drought-induced mortality selectively affects Scots pine trees that show limited intrinsic water-use efficiency responsiveness to raising atmospheric CO2
(CSIRO Publishing, 2014)Widespread drought-induced tree mortality has been documented around the world, and could increase in frequency and intensity under warmer and drier conditions. Ecophysiological differences between dying and surviving trees ... -
Endogenous circadian rhythms in pigment composition induce changes in photochemical efficiency in plant canopies
(Wiley, 2017-02-01)There is increasing evidence that the circadian clock is a signif- icant driver of photosynthesis that becomes apparent when environmental cues are experimentally held constant. We studied whether the composition of ... -
High-carotenoid maize: development of plant biotechnology prototypes for human and animal health and nutrition
(Springer Verlag, 2017-06-01)Carolight® is a transgenic maize variety that accumulates extraordinary levels of carotenoids, including those with vitamin A activity. The development of Carolight® maize involved the technical implementation of a novel ... -
Warming effects on Pinus sylvestris in the cold-dry Siberian forest-steppe: Positive or negative balance of trade?
(MDPI, 2017-12-07)Understanding climate change impacts on drought-prone forests is a critical issue. We investigated ring-width and stable isotopes (Δ13C and δ18O) in two Pinus sylvestris stands of the cold-dry Siberian forest-steppe growing ... -
Increasing drought effects on five European pines modulate Δ13C-growth coupling along a Mediterranean altitudinal gradient
(British Ecological Society, 2017-06-01)1. Climate warming increases vulnerability to drought in Mediterranean water-limited forests. However, we still lack knowledge of the long-term physiological responses of coexisting pine species in these forests regarding ... -
Quarantining the Sahara desert: growth and water-use efficiency of Aleppo pine in the Algerian Green Barrier
(Springer Verlag, 2017-02-01)The Algerian Green Barrier, mainly composed of native and artificial Aleppo pine forests, spreads along the pre-Saharan steppes and is threatened by anthropogenic and natural disturbances, including climate change. We ... -
Night and day - Circadian regulation of night-time dark respiration and light-enhanced dark respiration in plant leaves and canopies
(Elsevier, 2017)The potential of the vegetation to sequester C is determined by the balance between assimilation and respiration. Respiration is under environmental and substrate-driven control, but the circadian clock might also contribute. ... -
Circadian rhythms regulate the environmental responses of net CO2 exchange in bean and cotton canopies
(Elsevier, 2017)Studies on the dependence of the rates of ecosystem gas exchange on environmental parameters often rely on the up-scaling of leaf-level response curves ('bottom-up' approach), and/or the down-scaling of ecosystem fluxes ... -
The combined effects of a long-term experimental drought and an extreme drought on the use of plant-water sources in a Mediterranean forest
(Wiley, 2015)Vegetation in water-limited ecosystems relies strongly on access to deep water reserves to withstand dry periods. Most of these ecosystems have shallow soils over deep groundwater reserves. Understanding the functioning ...
