Abstract Tree mortality is a key factor influencing forest functions and dynamics, but our understanding of the mechanisms leading to associated changes in tree growth rates are still limited. We compiled new pan‐continental tree‐ring width database from sites where both dead living trees were sampled (2970 4224 190 sites, including 36 species), compared early recent between that died those survived given event. observed decrease radial before death ca. 84% events. The extent duration these...
Abstract Severe droughts have the potential to reduce forest productivity and trigger tree mortality. Most trees face several drought events during their life therefore resilience dry conditions may be crucial long-term survival. We assessed how growth severe droughts, including its components resistance recovery, is related ability survive future by using a tree-ring database of surviving now-dead from 118 sites (22 species, >3,500 trees). found that, across variety regions species...
Tree mortality is a key driver of forest dynamics and its occurrence projected to increase in the future due climate change. Despite recent advances our understanding physiological mechanisms leading death, we still lack robust indicators risk that could be applied at individual tree scale. Here, build on previous contribution exploring differences growth level between trees died survived given event assess whether changes temporal autocorrelation, variance, synchrony time-series annual...
Global change challenges forest adaptability at the distributional limit of species. We studied ring-porous Quercus canariensis Willd. xylem traits to analyze how they adjust spatio-temporal variability in climate. Trees were sampled along altitudinal transects, and annual time series radial growth (ring width (RW)) several earlywood vessel (EV) built their relationships with The trees responded increasing water constraints decreasing altitude changes climate short term but analyses showed...
Summary The extent to which water availability can be used predict the enlargement and final dimensions of xylem conduits remains an open issue. We reconstructed time course tracheid in Pinus sylvestris trees central Spain by repeated measurements diameter on microcores sampled weekly during a 2 yr period. analyzed role these dynamics empirically through time‐series correlation analysis mechanistically building model that simulates daily rate duration based Lockhart's equation potential as...
Plant-plant interactions influence how forests cope with climate and contribute to modulate species response future scenarios. We analysed the functional relationships between growth, competition for Pinus sylvestris, Quercus pyrenaica faginea investigate stand modifies forest sensitivity simulated annual growth rates of these different drought tolerance would change throughout 21st century. Dendroecological data from stands subjected thinning were modelled using a novel multiplicative...
Summary Climate change scenarios forecast rising temperatures for the Mediterranean region, which could enhance vulnerability to drought stress in forest ecosystems. The long‐term effects of climate forcing on tree performance can be, however, modulated by other environmental factors, such as competition and atmospheric CO 2 concentrations. We assessed concomitant effect competition, concentrations tree‐ring δ 13 C‐derived intrinsic water‐use efficiency ( iWUE ) basal area increments BAI...
Dendrochronology (i.e. the study of annually dated tree-ring time series) has proved to be a powerful technique understand tree-growth. This paper intends show interest using ecophysiological modeling not only and predict tree-growth (dendroecology) but also reconstruct past climates (dendroclimatology). Process models have been used for several decades in dendroclimatology, it is recently that methods model-data fusion led significant progress as function climate reconstructing climates....
Climate change may reduce forest growth and increase mortality, which is connected to high carbon costs through reductions in gross primary production net ecosystem exchange. Yet, the spatiotemporal patterns of vulnerability both short-term extreme events gradual environmental changes are quite uncertain across species' limits tolerance dryness. Such information fundamental for defining ecologically relevant upper species drought and, hence, predict risk increased mortality shifts...
Climatic scenarios for the Mediterranean region forecast increasing frequency and intensity of drought events. Consequently, a reduction in Pinus sylvestris L. distribution range is projected within region, with this species being outcompeted at lower elevations by more drought-tolerant taxa such as Quercus pyrenaica Willd. The functional response these to shifts water availability will partially determine their performance and, thus, competitive success under changing climatic conditions....
Abstract. Climatic drivers limit several important physiological processes involved in ecosystem carbon dynamics including gross primary productivity (GPP) and allocation vegetation. variability limits these two differently. We developed an existing mechanistic model to analyse photosynthesis evergreen species at Mediterranean forests. The was calibrated using a combination of eddy covariance CO2 flux data, dendrochronological time series secondary growth forest inventory data. modified be...
We present a review on the state-of-the-art of fruit prodution in Western Iberia woodlands («dehesas»), and particularly Q. ilex (holm oak) «dehesas». This threatened ecosystem is very high ecological economical importance. Quercus sp. fruits (acorns) are essential for wildlife, pig fattening In first part this we briefly describe phenology holm oak factors affecting acorn morphology chemical composition. second half analyze main known reported literature that determine production: pruning,...
Abstract In this paper, we present a new approach, based on mixed model procedure, to quantify the tree‐ring‐based growth‐climate relationship of trembling aspen along latitudinal gradient from 46 54 °N in eastern Canada. This approach allows breaking down growth response into general intersite and local climatic responses, analyzing variations absolute ring width as well interannual tree growth. The final also integrates nonclimatic variables such soil characteristics occurrence insect...
