Abstract Relatively anisohydric species are predicted to be more predisposed hydraulic failure than relatively isohydric species, as they operate with narrower safety margins. We subjected co‐occurring J uniperus monosperma and P inus edulis trees warming, reduced precipitation, or both, measured their gas exchange responses. found that reductions in stomatal conductance assimilation by heat drought were frequent during moist periods, but these effects not exacerbated the combined treatment....
Higher temperatures associated with climate change are anticipated to trigger an earlier start the growing season, which could increase terrestrial C sink strength. Greater variability in amount and timing of precipitation is also expected higher temperatures, bringing increased drought stress many ecosystems. We experimentally assessed effects temperature on foliar phenology shoot growth mature trees two semiarid conifer species. exposed field-grown a ~45% reduction rain-out structure...
Isohydry (i.e., strong regulation of leaf water potential, Ψl) is commonly associated with strict stomatal transpiration under drought, which in turn believed to minimize hydraulic risk at the expense reduced carbon assimilation. Hence, iso/anisohydric classification has been widely used assess drought resistance and mortality mechanisms across species, isohydric species being hypothetically more prone starvation anisohydric vulnerable failure. These hypotheses their underlying assumptions,...
Plants exhibit a variety of drought responses involving multiple interacting traits and processes, which makes predictions survival challenging. Careful evaluation within species, where individuals share broadly similar resistance strategies, can provide insight into the relative importance different processes. We subjected Pinus sylvestris L. saplings to extreme (no watering) leading death in greenhouse (i) determine effect predisposing factors on time, (ii) identify rank key predictors...
Seasonality in tree cambial activity and xylem formation encompass large variation environmental conditions. Abiotic stressors such as warming or drought also modulate plant behavior at species individual level. Despite susceptibility to carbon (C) water availability, it is still unknown which are the key physiological variables that regulate xylogenesis, what extent performance contributes further explain number of cells different phases development. Xylogenesis was monitored saplings Pinus...
Abstract Resin is a renewable forest resource that can increase the economic value of some forests in rural areas. production associated with climatic conditions. However, its impact on trees’ growth remains unclear. Here, we studied radial six Portuguese Pinus pinaster had been resin tapped for 5–7 years along latitudinal and gradient to understand whether tapping affects tree growth, how it affected by climate, stand traits. Tree-ring width ( TRW ) untapped trunk sides was compared before...
Abstract Short‐term plant respiration ( R ) increases exponentially with rising temperature, but drought could reduce by reducing growth and metabolism. Acclimation may alter these responses. We examined if species different responses would differ in foliar response to +4.8°C temperature −45% precipitation a field experiment mature piñon juniper trees, any differences between were related photosynthesis rates, shoot nonstructural carbohydrates (NSCs). had Q 10 of 1.6 for 2.6 juniper.

<p>Resin is a natural defensive substance produced by trees in response to injury and infection sustainable valuable non-timber forest product. Resin tapping traditional activity that besides increasing the economic profit of plantations, it provides ecosystem services promotes development rural areas. However, effect resin on tree growth remains elusive. Furthermore, there evidence connecting production with climatic conditions, but tree-growth responses conditions stand...
