Groundwater Changes the Climate Niche of an Amazonian Mound‐Building Termite

open access: yesEcohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT Rainfall is a major dimension of species climate niches. It has been proposed that groundwater can change species responses to rainfall by creating ‘hydrological refugia’ under a drier climate. However, the available evidence is conflicting and biased towards plants.
