The Wetzel Lab studies the role of variability in ecology. Our work focuses on how changing levels of biological diversity and climate variability influence plants and insects. We work in natural and agricultural ecosystems and strive to answer fundamental questions with implications for environmental issues. We strive to link patterns at population and community scales with mechanisms at the organismal scale. The lab does this by using mathematical and statistical modeling to integrate field and lab data. We also place an emphasis on using meta-analysis, synthesis, and global collaboration to search for general answers to fundamental ecological questions.
