Anna Sher, Ph.D.
Adjunct Researcher, former Gardens Director of Research & Conservation
Dr. Anna Sher is a plant ecologist with a particular interest in conservation issues and expertise in ecology and restoration of Tamarix (tamarisk, saltcedar) invasions.Her research also includes investigation of climate change using historical plant databases from herbaria.
From 2003-2010, she held a joint position with the University of Denver, and remains professor of biology there.
Dina Clark, M.S.
Adjunct Researcher, former Kathryn Kalmbach Herbarium Curator
Ms. Clark is a collections manager at the University of Colorado Herbarium. Her work has focused on the floristics and conservation in the eastern plains of Colorado. Dina has conducted floristic inventories, rare plant surveys and ecological research on federal, state and private lands. Recent field projects include assisting the Colorado Natural Heritage Program with a 2007 and 2009 biological inventory of southeastern Colorado, and a floristic inventory of the Windy Point Area of Pikes Peak for the USDA Pike-San Isabel National Forest. She is currently working along the Arikaree River in Yuma County and in South Park.
Donald Hazlett, Ph.D.
Dr. Hazlett is an ethnobotanist with expertise in human uses of plants in the western United States and in Latin America. He received his doctorate from the University of Washington, Seattle in Tropical Ecology. Dr. Hazlett is fluent in Spanish and has been an instructor for the School for Field Studies in both Costa Rica and Ecuador. His work at the Gardens has focused on establishing the ethnobotanical collection at KHD, with an emphasis on Latin American plant uses, and screening plants native to Colorado for alkaloids. He is a field biologist and has taught at Colorado State University, University of Colorado, University of Northern Colorado, University of Denver and at several community colleges in Colorado. (The Society of Ethnobiology will be hosting its annual meeting at the Gardens April 11-14, 2012.)
Leo Bruederle, Ph.D.
Dr. Bruederle’s interests include the evolution of species rich genera such as Carex (Cyperaceae), which comprises approximately 2000 species worldwide. He is interested in the evolutionary mechanisms that facilitate speciation in this large genus, and has many publications in this area. Additional interests include: plant systematics at and below the level of genus, population genetics and endemism, and conservation genetics. Dr. Bruederle is currently associate professor at the University of Colorado Denver.
Ms. Yeatts is an active field botanist and taxonomist. She has conducted numerous botanical surveys, including an important survey of the Rocky Mountain National Park with KHD herbarium staff. Her current research focuses on the flora of Gateway Natural Area, where she and her husband are volunteer stewards. Her floristic studies and field work have contributed to building the collection with almost 6,000 high quality specimens. In addition to her floristic work, Loraine is an accomplished wildflower photographer with contributions to publications including the recent book by Dan Johnson, “Meet the Natives.” She is also author of “Alpine Flower Finder” with Dr. Janet Wingate. Loraine recently helped describe a new, possibly rare species of Packera, Packera mancosana, with L. Yeatts, B. Schneider, & A. Schneider.
Martin Quigley, MLA, Ph.D.
Dr. Quigley is a professor in biological sciences and the director of the Arboretum at the University of Denver. He is a forest community ecologist, and a licensed landscape architect with a goal of integrating environmental functionality into the constructed landscape. He has worked throughout the Intermountain West on historic landscape renovations, rails-to-trails conversions, vegetation surveys and other environmental analyses, and botanic garden enhancements.
His current research foci include stewardship and restoration of fragmented second-growth forests in the urban matrix, park stewardship, green roof plantings with native species, the creation of vegetated swales for filtration of urban runoff, mycorrhizal remediation of drought stress in cultivated plants, and pre-emption of woody exotic invasives on an urban to rural gradient.
Scott Bates, Ph.D.
Dr. Bates is an active researcher with an academic background in plant biology, lichenology, microbiology, mycology and molecular microbial ecology. He currently works at the University of Colorado (CIRES) in the lab of Dr. Noah Fierer, where he has been involved with diverse projects such as surveying soil microbes of Sub-Saharan Africa, examining global patterns of soil archaea, and investigating the diversity of microbes associated with the lichen symbiosis. At the Gardens' Sam Mitchel Herbarium, he has concentrated on the taxonomy of gasteroid fungi (e.g., “puffballs” and “earthstars”) of this region using classical and modern DNA-based approaches. His current focus is the genus Tulostoma, comprising ca. 100 gasteroid species. The herbarium’s extensive collections in this genus have provided rich material for study. Additionally, he hopes to help with the effort to make herbarium data on Colorado fungi interactively available to the public via the Internet.
Cara Gibson, Ph.D.
Dr. Gibson was trained as an entomologist and her interests include ecology, biodiversity, and interactions with microbial symbionts. She has worked as a field ecologist, research scientist, educator, outreach coordinator, and scientific illustrator. Dr. Gibson’s work with the Gardens supports ongoing studies involving plants and their insect pollinators.
