“…3), and radially enlarging tracheids are tightly related to annual growth rates (Horáček et al 1999). As tested in early studies (Ziaco et al 2018;Pompa-García et al 2021), the availability of water before and during early spring, when temperatures start rising, seems to explain the rate of cellular production. Also wood anatomical features mirror the role of climatic conditions by increasing the number of radially-enlarging tracheids (Fig.…”

“…As a further effort to improve the explanations of climate-growth relationships at annual and seasonal scales, remote sensing data have been used to monitor changes in forest productivity and canopy greenness (e.g., Pompa-García et al 2021 ). As a result, remote sensors are a flexible, reliable and a widely recognized tool to study the intra-annual changes in radial growth and canopy greenness in forests (Decuyper et al 2020 ).…”

“…As a result, remote sensors are a flexible, reliable and a widely recognized tool to study the intra-annual changes in radial growth and canopy greenness in forests (Decuyper et al 2020 ). Among the most used remote sensing variables, the Normalized Difference Vegetation Index (NDVI) is considered as a valuable proxy to investigate the effects of climate variability on vegetation phenology and productivity due to its close relationship with plant activity and canopy greenness and cover (Gazol et al 2018 ; Pompa-García et al 2021 ). Thus, when radial-increment dynamics data and remote sensing are integrated, the explanatory capacity of these variables allows disentangling ecological strategies used by tree species to withstand drought stress (Vicente-Serrano et al 2020 ).…”

“…There are some studies dealing with the climatic drivers of tree growth and NDVI data in high-elevation forests from central Mexico (Correa-Díaz et al 2019 , 2020 ), and in semi-arid forests from northern Mexico and the south-western USA (Villanueva-Díaz et al 2009 ; Pompa-García et al 2013 ; González-Casares et al 2017 , 2020 ; Szejner et al 2020 ). However, intra-annual xylogenesis studies are still scarce in this region (but see Belmecheri et al 2018 ; Ziaco et al 2018 ; Pompa-García et al 2021 ). Therefore, here we aim to analyze the inter- and intra-annual links between climate, tree growth and NDVI data of Pinus teocote , a conifer species abundant in the study region.…”

The inter- and intra-annual variability in radial growth reflects responses to climatic variability and water shortage, especially in areas subjected to seasonal drought. However, it is unknown how this variability is related to forest productivity, which can be assessed by measuring changes in canopy greenness and cover through remote sensing products as the Normalized Difference Vegetation Index (NDVI). We combine xylogenesis with measurements of inter-annual changes in seasonal wood production (earlywood width, adjusted latewood width) and NDVI to improve the understanding of climate and drought impacts on growth and forest productivity in a Pinus teocote stand located in northern Mexico. Cambial dynamics accelerated in March and a high production of radially enlarging and thickening tracheids were observed from April to October and from June to October, respectively. Tracheid maturation was very active in October when latewood production peaked. Wet conditions in winter-spring and summer-autumn enhanced earlywood and latewood production, respectively. Earlywood and latewood were constrained by long (4–10 months) and short (2–3 months) droughts, respectively. The earlywood production depended on April soil moisture, which agrees with the peak of radially enlarging tracheid production found during that month. Aligning drought proxies at inter- and intra-annual scales by using growth and productivity measures improves our understanding of conifer forest responses to water shortage.

“…Radial growth, in contrast to height growth, has been much more studied relative to drought through dendrochronological, dendrometer and xylem anatomy studies. However, although latewood and earlywood sensitivity to climate ( Michelot et al 2012 ; D’Orangeville et al 2013 ; Pompa-García et al 2021 ) as well as xylem anatomical features ( Rossi et al 2009 ) generally reflect the season in which they form, the most common studied feature is total ring-width sensitivity to climate. Our study provides further justification for the value of intra-annual measurements, e.g.…”

Drought timing and species growth phenology determine intra-annual recovery of tree height and diameter growth

Droughts interact with tree phenology to drive declines in growth. As climate change makes drought more likely in the northeastern United States, it is important to understand how droughts at different times of year will lead to reduced height and diameter growth of trees. To determine how seasonal drought may reduce intra-annual growth, we implemented spring, summer, or fall droughts on 288 containerized saplings of six tree species (Acer rubrum, Betula papyrifera, Prunus serotina, Juniperus virginiana, Pinus strobus, and Thuja occidentalis). We tracked weekly soil moisture, leaf water potential, height, diameter, and survival of all trees before, during, and after each 6-week drought. We found that the tree species that conducted the majority of their height or diameter growth in the spring were most sensitive to spring droughts (B. papyrifera and P. strobus). T. occidentalis also experienced significantly reduced growth from the spring drought but increased growth after the drought ended and achieved total height and diameter growth similar to controls. In contrast, for most species summer droughts halted growth in most species for the remainder of the growing season even after the drought had ended. Fall droughts never impacted growth in the current year. These fine temporal-scale measurements of height and diameter growth suggest that tree response varies among species and is dynamic at intra-annual scales. These relatively rare data on intra-annual height growth sensitivity are important for canopy recruitment of saplings in forest ecosystems. Species-specific sensitivities of intra-annual growth to drought can inform models of forest competition in a changing climate.
