The hygrothermal stress or harsh environment hypothesis considers that xeric sites harbour higher local gall-inducing insect
richness than mesic sites because of a combination of abiotic stress such as a dry climate would benefit endophytophages such as gallers, decrease predators and parasitoid attack (Fernandes and Price 1992) and the suite of morphological and physiological characters shown by scleromorphic plants in these sites, such as resistant and long-lived leaves, low levels of plant defence investment.
