We evaluated the response of Earth land biomes to drought by correlating a index with three global indicators vegetation activity and growth: indices from satellite imagery, tree-ring growth series, Aboveground Net Primary Production (ANPP) records. Arid humid are both affected drought, we suggest that persistence water deficit (i.e., time-scale) could be playing key role in determining sensitivity drought. found arid respond at short time-scales; is, there is rapid reaction as soon deficits...
Drought effects on carbon cycling The response of forest ecosystems to drought is increasingly important in the context a warming climate. Anderegg et al. studied tree-ring database 1338 sites from around globe. They found that forests exhibit “legacy effect” with 3 4 years' reduced growth following drought. During this postdrought delay, will be less able act as sink for carbon. Incorporating legacy into Earth system models provide more accurate predictions global cycle. Science , issue p. 528
Abstract In this study, the authors provide a global assessment of performance different drought indices for monitoring impacts on several hydrological, agricultural, and ecological response variables. For purpose, they compare [the standardized precipitation index (SPI); four versions Palmer severity (PDSI); evapotranspiration (SPEI)] to predict changes in streamflow, soil moisture, forest growth, crop yield. The found superior capability SPEI SPI indices, which are calculated time scales...
Summary Some disturbances can drive ecological systems to abrupt shifts between alternative stages (tipping points) when critical transitions occur. Drought‐induced tree death be considered as a nonlinear shift in vigour and growth. However, at what point do trees become predisposed drought‐related dieback which factors determine this (tipping) point? We investigated these questions by characterizing the responses of three species, silver fir ( A bies alba ), S cots pine P inus sylvestris )...
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...
• Seasonal radial-increment and xylogenesis data can help to elucidate how climate modulates wood formation in conifers. Few studies have assessed plastic is sympatric conifer species from continental Mediterranean areas, where low winter temperatures summer drought constrain growth. Here, we analysed intra-annual patterns of secondary growth (Juniperus thurifera, Pinus halepensis sylvestris). Two field sites (xeric mesic) were evaluated using dendrometers, microcores climatic data. A...
Abstract Forecasted increase drought frequency and severity may drive worldwide declines in forest productivity. Species‐level responses to a drier world are likely be influenced by their functional traits. Here, we analyse resilience using an extensive network of tree‐ring width data satellite imagery. We compiled proxies growth productivity ( TRW i, absolutely dated ring‐width indices; NDVI , Normalized Difference Vegetation Index) for 11 tree species 502 forests Spain corresponding...
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...
Abstract Aim The intensity and frequency of drought have increased considerably during recent decades in some Northern Hemisphere forested areas, future climate warming could further magnify stress. We quantify how forests resist events recover after them, i.e. we determine their growth resilience. Location North America Europe. Methods use a large tree‐ring database to study influences forest selected 775 width chronologies studied the occurrence years with extremely dry conditions (low...
Understanding how plants survive drought and cold is increasingly important as worldwide experience dieback with in moist places grow taller warming ones. Crucial plant climate adaptation are the diameters of water-transporting conduits. Sampling 537 species across zones dominated by angiosperms, we find that size unambiguously main driver conduit diameter variation. And because have wider conduits, conduits within more vulnerable to conduction-blocking embolisms, conspecifics should be than...
Abstract Tree populations located at the geographical distribution limit of species may provide valuable information about tree‐growth response to changes on climatic conditions. We established nine Pinus nigra , 12 P. sylvestris and 17 uncinata tree‐ring width chronologies along eastern northern Iberian Peninsula, where these are found edge their natural range. Tree‐growth variability was analyzed using principal component analysis (PCA) for period 1885–1992. Despite diversity species,...
Abstract. In 2009, the International Soil Moisture Network (ISMN) was initiated as a community effort, funded by European Space Agency, to serve centralised data hosting facility for globally available in situ soil moisture measurements (Dorigo et al., 2011b, a). The ISMN brings together collected and freely shared multitude of organisations, harmonises them terms units sampling rates, applies advanced quality control, stores database. Users can retrieve from this database through an online...
Significance Climatic warming is expected to shift alpine treelines upward because regeneration and growth of trees there are limited by low temperature. However, treeline displacement spatially heterogeneous, despite climate. Using data on undisturbed spruce fir plots located the Tibetan Plateau between 28.4 38.5°N, we showed that climatic tended promote an at local regional scales. upslope migration rates were controlled largely interspecific interactions. The species interaction mechanism...
Summary 1. Long‐term basal area increment (BAI) in Abies pinsapo was studied to investigate the way density‐dependent factors modulate responses of radial growth climatic stresses relict stands a drought‐sensitive Mediterranean fir. 2. First, we verified that spatially explicit competition predicts mean A. BAI at our study site; i.e. it modulates degree which average climate‐driven potential for is expressed. Second, long‐term pattern temperature BAI, estimated as main trend over time period...
Abstract Global climate change is expected to further raise the frequency and severity of extreme events, such as droughts. The effects droughts on trees are difficult disentangle given inherent complexity drought events (frequency, severity, duration, timing during growing season). Besides, might be modulated by trees’ phenotypic variability, which is, in turn, affected long‐term local selective pressures management legacies. Here we investigated magnitude temporal changes tree‐level...
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...
Significance Forest trees can live for hundreds to thousands of years, and they play a critical role in mitigating global warming by fixing approximately 15% anthropogenic CO 2 emissions annually wood formation. However, the environmental factors triggering formation onset springtime cellular mechanisms underlying this remain poorly understood, since forms beneath bark is difficult monitor. We report that Northern Hemisphere conifers driven primarily photoperiod mean annual temperature....
Climate change can lead to the simultaneous occurrence of extreme droughts and heat waves increasing frequency compound events with unknown impacts on forests. Here we use two independent datasets, a compiled database tree drought mortality ICP-Forest level I plots, study hot summers, elevated vapour pressure deficit (VPD), dry years forest defoliation across Europe. We focused background rates, studied their co-occurrence summers years. In total, 143 out 310 Europe, i.e. 46% cases,...
Significance Forests are experiencing growing risks of drought-induced mortality in a warming world. Yet, ecosystem dynamics following drought remain unknown, representing major limitation to our understanding the ecological consequences climate change. We provide an emerging picture postdrought trajectories based on field indicators forest dynamics. Replacement patterns indicate limited short-term persistence predrought dominant tree species, highlighting potential for reorganization coming...
Recent studies have identified strong relationships between delayed recovery of tree growth after drought and mortality caused by subsequent droughts. These observations raise concerns about forest ecosystem services post-drought given the projected increase in frequency extremes. For quantifying impact extreme droughts on radial growth, we used a network tree-ring width data 1689 trees from 100 sites representing most distribution two tolerant, deciduous oak species (Quercus petraea Quercus...
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...
