Drought-triggered declines in forest productivity and associated die-off events have increased considerably due to climate warming the last decades. There is an increasing interest quantifying resilience capacity of forests against drought uncover how different stands tree species will resist recover after more frequent intense droughts. Trees form annual growth rings that represent accurate record responded past Here we use dendrochronology quantify radial subjected contrasting climatic...
Tree species display a wide variety of water-use strategies, growth rates and capacity to tolerate drought. However, if we want forecast cope with increasing aridity drought, need identify which measurable traits confer resilience drought across species. Here, use global tree ring network (65 species; 1931 site series ring-width indices-RWI) evaluate the relationship long-term growth-drought sensitivity (RWI-SPEI index relationship) short-term response extreme episodes (resistance, recovery...
Abstract The negative impacts of drought on forest growth and productivity last for several years generating legacies, although the factors that determine why such legacies vary across sites tree species remain unclear. We used an extensive network tree‐ring width (RWI, ring‐width index) records 16 from 567 forests, high‐resolution climate normalized difference vegetation index (NDVI) datasets Spain during common period 1982‒2008 to test hypothesis conditions features modulate legacy effects...
The increase in frequency and intensity of droughts due to climate change might threaten forests under stress levels causing dieback mortality episodes. Thus, deciphering how tree species from within a region respond drought along environmental gradients should help us understand forest vulnerability change. To enlighten contrasting responses dominant species, we reconstructed vegetation activity using Normalized Difference Vegetation Index (NDVI) radial growth tree-ring width series. We...
Abstract Climate extremes, such as abnormally dry and wet conditions, generate abrupt shifts in tree growth, a situation which is expected to increase under predicted climate conditions. Thus, it crucial understand factors determining short‐ long‐term performance response higher frequency intensity of extremes. We evaluated how three successive droughts years influenced growth six dominant Iberian species. Within species variation repeated was function individual traits related resource...
Abstract Tree‐ring data has been widely used to inform about tree growth responses drought at the individual scale, but less is known how sensitivity scales up driving changes in forest dynamics. Here, we related tree‐ring chronologies and stand‐level basal area from two independent sets test if match stand dynamics (stand growth, ingrowth, mortality). We assessed covary as a function of spatial scale taxa (gymnosperm or angiosperm). To this end, compared network with Spanish National Forest...
Spatial and temporal variation in functional traits allows trees to adjust shifting environmental conditions such as water stress. However, the change of traits, both mean variances, along availability gradients across growing seasons, well their covariation with tree performance, have been rarely assessed. We examined intraspecific trait coexisting evergreen (Quercus ilex ssp. Q. ballota) deciduous faginea Quercus humilis) Mediterranean oaks a wide gradient northeastern Spain during six...
Summary The climatic significance and ecosystem implications of latewood intra-annual density fluctuations (IADFs) are still not fully understood in Mediterranean ring-porous oak species. To solve this issue, we investigated: (i) the climate drivers radial growth IADFs Quercus faginea , (ii) whether they were correlated to increased canopy cover greenness as recorded by Normalized Difference Vegetation Index (NDVI). formed mid late characterized rows parenchyma cells. Such uncommon only...
Abstract Experimental evidence indicates that more diverse communities sustain higher levels of ecosystem functioning. Generally, bottom-up processes accounting for community selection and complementarity effects on biodiversity are used to explain However, top-down macroecological can also influence the distribution functions across large environmental gradients and, importantly, patterns. Here, we tested whether past climate instability, current climate, climate-driven species abundance...
