description: We have attached the information on the database used and the analyses performed to obtain the results in the manuscript. Also attached are the statistical programs and software that users can use to obtain the information.1) Tree ring width measurement was performed using the free software COFECHA and the TSAP-Win v.4.67c2) Measurements of anatomical functional traits were performed with the aid of free access software ImageJ.3) Spatial analysis of <i>Magnolia gentryi</i> and climate data were achieved with the free access software SADIE v1.22, and the SURFER v. 26.1.2164) We performed statistical analyses using the software R.DATABASE CONTENTSThe databases contain <i>Magnolia gentryi</i> chronology (chronology.csv), dasometric traits (Dasometric_assessments.txt), wood anatomical traits (Wood anatomical_assessments.txt), leaf vein traits (Leaf vein_assessments.text), climate data (Climatic_data.csv). A description of the included variables follows:chronology.csv: Tree ring width information and year of formation.column A in the database represents the years, and column B represents the ring width index data (mm). The rows mean the data.Dasometric_assessments.txt: Dasometric metrics of <i>Magnolia gentryi</i>.column A in the database represents Tree height (m), column B represents the DBH (cm), and column C represents Bark thickness (cm).Wood anatomical_assessments.txt: Measurements of wood anatomical traits for the Andean Magnolia species studied (<i>Magnolia gentryi</i>): We considered hydraulic diameter (DH, mm), vulnerability index (VI, 1 to &gt; 3), fiber lumen diameter (FD, mm), fiber length (FL, mm), and fiber wall thickness (FWT, mm)column A, row 2 in the database represents hydraulic diameter, the column B, row 2 represents the vulnerability index, the column C, row 2 represents fiber lumen diameter, the column D, arrow 2 represents the fiber length, and the column E represents fiber wall thicknessThe rows 2-222 are represented by the wood anatomical trait measurements.Leaf vein_assessments.text: Measurements of leaf vein traits for the <i>Magnolia gentryi</i>: We considered vein density (mm∙mm−2), vein length (cm), leaf base angle, and leaf shape (qualitative).Column A, row 1 in the database represents vein length (cm); column B, row 1 represents leaf base shape (0, 1, 2); column C, row 1 represents leaf shape (elliptic= 0, oblong= 1, elliptic-lanceolate= 2) and the column D, row 1 represents vein density (mm·mm−2).The rows 2-41 are represented by the leaf vein trait measurements.Climatic_data.cvs: We used the monthly precipitation (Prec), evapotranspiration (EvT) in mm, mean maximum, and minimum temperature (tmax and tmin) in °C, from the CHELSA database (Karger et al. 2021), and the layer resolution was c. 1 km2, with records spanning from 1980 to 2018.Column A in the database represents the PREC in mm; column B represents EvT in mm; column C represents tmax in ºC; and column D represents tmin in ºC.Additional informationCOFECHA (https://www.ltrr.arizona.edu/pub/dpl/A-INFO.HTM).-(opens in new window) Dating and measurement tree-ring quality control.TSAP-Win (https://rinntech.info/products/tsap-win/).-(opens in new window) Is used for analysis in dendrochronology, climate change, ecological patterns, growth and yield studies, and any application requiring accurate analysis of annual rings.ImageJ (https://imagej.nih.gov/ij/download.html).-(opens in new window) The software is used to measure the characters of xylem vessels manually.SADIE (https://repository.rothamsted.ac.uk/latest).-(opens in new window) They outline the software to measure and test spatial patterns in data from a single species and for spatial association species vs climate data.SURFER (www.goldensoftware.com).-(opens in new window) Surfer helps engineers and scientists interpret complex geospatial datasets and transform them into insightful and understandable publication-ready modelsR-software (https://www.r-project.org/).-(opens in new window) The program is used to complete all statistical analyses performed in the manuscript.
