Various native and exotic insects and diseases affect the forest ecosystems of the Hoosier-Shawnee Ecological Assessment Area. Defoliating insects have had the greatest effects in forests where oak species predominate. Increases in oak decline are expected with the imminent establishment of the…

Diet-induced thermogenesis (DIT) is a concept that has been well known in one form or another for more than a century in vertebrate nutrition and physiological ecology. Yet, it is practically unknown in the physiology and nutritional ecology of insects. We suggest that DIT is a ubiquitous mechanism…
