The Garnas Lab focuses broadly on better understanding the diversity, frequency, and consequences of novel interactions in forest ecosystems that occur as species ranges shift with biological invasion and climate change. Our study systems include emerald ash borer, beech bark disease, beech leaf disease, and southern pine beetle in forests of the northeastern United States. Our team uses these study systems (among others) to ask a variety of questions about the ecology and evolution of insects and microbes in forest systems.
