The expectation is that as latitude increases, the \u03b1 diversity of VOCs may decrease due to harsher environmental conditions and evolutionary pressures, while \u03b2 diversity may increase as different sites exhibit distinct VOC profiles due to varying ecological interactions. The goal is to understand these patterns to gain insights into plant-parasite dynamics and ecological diversity."}
