What I do

My research program at University of Denver has three, overlapping foci: 1) preservation of rare species, 2) the ecology of exotic invasive species, and 3) restoration of degraded ecosystems. The primary concentration of the Sher Lab has been the ecology of restoration of riparian habitats invaded by non-native plants. I mentor graduate and undergraduate students doing research in these areas and teach upper division courses including Conservation Biology, Invasive Species Ecology, and Advanced Research Methods (an upper-level statistics class).

Professional Biography

Anna A. Sher is a full professor in the Department of Biological Sciences at the University of Denver. Receiving her Ph.D. from the University of New Mexico, she pursued post doctoral work as a Fulbright fellow in Israel to investigate plant interactions at Ben Gurion University’s Mitrani Department of Desert Ecology, and she also studied the biology and control of an invasive grass at the University of California, Davis. She has also taught ecology at Earlham College where she regularly led the Kenya Study Abroad Program. Dr. Sher is an international expert in the ecology and management of invasive Tamarix trees; her research includes not only restoration ecology and invasive species biology, but also insect biocontrol, ethnobotany, climate change, and rare species conservation. Since arriving in Denver in 2003, Dr. Sher has also served as Director of Research and Conservation at Denver Botanic Gardens, and as a visiting lecturer at the University of Otago, Dunedin, New Zealand. She is co-author of the textbook series Ecology Concepts and Applications (Molles and Sher 2018). Dr. Sher loves to teach students, whether it be through lecturing, collaborative research, mentoring, or writing.

Research

Our current projects involve investigating plant community response to the removal of exotic Tamarix (tamarisk, saltcedar) trees in the Southwestern United States and the human element of this response. We do this using multivariate statistical methods that explore patterns on the basis of nativity, functional traits, and characteristics of the land managers responsible for the restoration projects. We are also currently using high altitude benthic communities to test hypotheses about anthropogenic impacts. Past projects have included documenting phenological shifts in high altitude plants in response to climate, conservation of rare plants, and the impact of invasive species on ecosystems.
