Research Description

The intensification of human land use and changing climate are fundamentally altering freshwater ecosystems. Urbanization in particular impairs water quality, increases water temperatures, and in many cases has resulted in complete elimination of natural water bodies. How do these broad-scale factors influence the distribution of aquatic insects, which have both aquatic and terrestrial life stages? To answer this question, I focus on a particularly eye-catching and popular group that people have collected extensively over the past 100 years, the dragonflies. My research explores changes dragonfly communities and individual species distributions in California and Nevada over the past century.
