Overview

Comparative trait analysis uncovers climate-driven trade-offs between nutritional and protective gall tissues in Neotropical plants, indicating that gall anatomy mirrors environmental conditions.

Key Points

To determine whether plant gall anatomical traits and compartment resource allocations respond functionally to environmental gradients across diverse Neotropical systems.
Compiled anatomical literature data on Neotropical plant galls, standardized structural traits, and calculated a Tissue Investment Index to quantify internal versus external compartment allocation.
Classified morphotypes into morphofunctional profiles using multivariate ordination and hierarchical clustering, then evaluated associations with climatic variables using redundancy analysis and generalized mixed models.
Humidity and solar radiation were the climatic variables most strongly associated with morphoanatomical variation, together explaining approximately 16% of total trait variation.
Higher humidity was associated with increased cellular hypertrophy, hyperplasia, and greater tissue investment in internal nutritional compartments.
Solar radiation was positively linked to epidermal thickness and parenchyma homogenization, enhancing water retention and metabolic efficiency under high irradiance.
