Limited evidence of coupling between above and belowground functional traits in tropical dry forest seedlings

Introduction: Water availability is one of the main factors determining the distribution of woody species in the tropics. Although the functional mechanisms that determine the species tolerance to water deficit have been extensively studied in adult individuals, the responses of early ontogenetic st...

We explored the relationships between pairs of traits using Pearson correlations, and to obtain an integrated view of the functional traits, a principal component analysis (PCA) was performed.

The incorporation of root traits helps to explain new functional strategies not reported for leaf and stem traits. This study contributes to understanding the mechanisms that explain species coexistence and is particularly relevant for predicting future forest trajectories.BarranquillaBiologíaSede NortePaez, JuanDominguez-Haydar, YamilethSalgado-Negret, Beatriz2022-12-19T02:42:48Z2022-12-19T02:42:48Z2021-06-302021-04-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtículoapplication/pdfapplication/pdfArrieta-González, R., Paez, J., Dominguez-Haydar, Y., & Salgado Negret, B.
