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...
• Tree features may modulate the sensitivity of radial growth to climate, leading a nonuniform response. Age-related increases in climatic have been observed repeatedly. Sex-related is also possible because long-term differential reproductive cost between sexes. This study analysed simultaneous effects age and sex on tree-ring climate. Ring widths were measured from 50 female male Juniperus thurifera trees, 50–350 yr old, growing under Mediterranean continental Response functions calculated...
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...
Summary This study addresses relationships between leaf phenology, xylogenesis, and functional xylem anatomy in two ring‐porous oak species, the temperate Quercus robur sub‐Mediterranean Q. pyrenaica . Earlywood vessel ( EV ) formation phenology were monitored 2012 2013. Ten individuals per species sampled at each of three sites located NW Iberian Peninsula. areas measured on microcore sections used to calculate hydraulic tree diameter D h ), order model phenology. Thermal requirements...
Abstract Aim We investigate the effects of environmental and geographical processes driving growth resilience recovery in response to drought Mediterranean Pinus pinaster forests. explicitly consider how intraspecific variability modulates drought. Location Western basin. Methods analysed tree rings from a large network 48 forests (836 trees) encompassing wide ecological climatic gradients, including six provenances. To characterize major constraints P. under extremely dry conditions, we...
A detailed understanding of how the climate models hydraulic system trees is still lacking, in spite need to understand tree response ongoing process climatic change. systematic correlation tracheid anatomical features with has not been implemented Mediterranean ecosystems, where change expected be particularly intense. We measured ring width and cell number—in addition intraring position, lumen size, wall thickness tracheids—in 10 Juniperus thurifera individuals from north-central Spain....
Summary Tree‐ring anatomy reflects the year‐by‐year impact of environmental factors on tree growth. Up to now, research in this field has mainly focused hydraulic architecture, with ray parenchyma neglected despite growing recognition its relevance for xylem function. Our aim was address gap by exploring potential annual patterns as a climate proxy. We constructed ring‐width and ray‐parenchyma chronologies from 1965 2004 20 Juniperus thurifera trees Mediterranean continental climate....
Tree rings provide information about the climatic conditions during growing season by recording them in different anatomical features, such as Intra-Annual Density Fluctuations (IADFs). IADFs are intra-annual changes of wood density appearing latewood-like cells within earlywood, or earlywood-like latewood. The occurrence is dependent on age and size tree, it triggered drivers. variations IADF frequency species their dependence climate across a wide geographical range have still to be...
Summary Environmental conditions and the structure of dormant cambium are assumed to affect seasonal patterns cambial activity, hence controlling allocation non‐structural carbohydrates ( NSC ) growth. However, dynamics xylogenesis, their connections with content size, have been rarely assessed along an environmental gradient. We monitored xylogenesis leaf phenology during 2012 2013, in 2012, for drought‐sensitive Quercus robur drought‐tolerant pyrenaica a water‐availability gradient...
Abstract Aim The Mediterranean Basin is considered to be a climate‐change hotspot, for which rising temperatures and associated aridification have been forecast. Such trends could affect the performance growth of conifers in these drought‐prone areas. We evaluated whether radial wood density can act as proxy measures precipitation drought conifer. Location Iberian Juniperus thurifera forests northern eastern Spain. Methods sampled 10 stands encompassing J. 's distributional area. related...
Drought is one of the key natural hazards impacting net primary production and tree growth in forest ecosystems. Nonetheless, species show different responses to drought events, which make it difficult adopt fixed tools for monitoring impacts under contrasting environmental climatic conditions. In this study, we assess response a satellite proxy (NPP) peninsular Spain Balearic Islands, region characterized by complex climatological, topographical, characteristics. Herein, employed three...
