Mary M. Gardiner, Ph.D – Lab Director
Dr. Mary M. Gardiner received her Ph.D. in 2008 and is currently an Associate Professor in the Department of Entomology at The Ohio State University. Her research program focuses on the ecological value of urban vacant land. This work is concentrated in Cleveland, Ohio – a city that has experienced significant economic and population decline. Cleveland currently contains 27,000 vacant lots encompassing approximately 4,000 acres of land. The Gardiner Lab examines how alternative vegetation designs and management regimes influence the value of vacant land for the conservation of biodiversity and the provision of ecosystem services. Mary is also a State Specialist in Extension and works with several stakeholder groups including home gardeners, Master Gardeners, Master Naturalists, and urban farmers. Her extension programming focuses on identifying and attracting beneficial insects to gardens and farms to promote conservation and ecosystem services. In 2015, she released a book focused on natural enemies and their role in biological control in home gardens titled: Good Garden Bugs: Everything You Need to Know about Beneficial Predatory Insects. She has also embraced the use of citizen science in her research with the statewide program, Pollination Investigators, which engages volunteers in the study of pollination services.
Postdoctoral Scientists
Kayla I. Perry, Ph.D.
Kayla is a USDA NIFA Postdoctoral Fellow (2018) and her research interests are focused on understanding the drivers that influence how insect communities are assembled and maintained to foster ecosystem services, with an emphasis on the role of natural and anthropogenic disturbances. She graduated with her Ph.D. in Entomology in 2016 from Ohio State University where she was advised by Dr. Dan Herms. Kayla’s research focused on elucidating mechanisms that explain the role of disturbance in maintaining ground-dwelling arthropod diversity, structure, and function in forest ecosystems by investigating the effects of emerald ash borer, wind from a tornado, and salvage logging. She also developed a novel method to quantify the movement of arthropods to understand recolonization potential following disturbance. Kayla joined the Gardiner Lab in 2017 to investigate regional and local processes of community assembly for ground-dwelling beetles and ants in Cleveland, Ohio using a functional trait-based approach.

Graduate Students
Yvan Delgado de la Flor
Originally from Lima-Peru, Yvan received his B.S. in Wildlife Conservation and Management at Humboldt State University in 2014. Yvan’ research experience includes studying mesocarnivores in the coastal dunes of northern California at HSU, and spider richness and abundance in Harvard Forest. He joined the Gardiner’s Lab in Fall 2014 and examined the diversity of ground and rove beetles from vacant lots in Cleveland, Ohio. Yvan has two projects ongoing. He is examining spider communities in Cleveland, more specifically food-web interactions among spiders, prey items, vegetation, and soil quality. Additionally, Yvan is surveying and cataloging the diversity and distribution of spiders in Cusco, Peru
Denisha M. Parker
Denisha attended Rust College, majoring in Biology for her undergraduate degree. An internship during the summer of 2013 at The Ohio State University in Dr. Mary Gardiner’s lab stimulated her interest in Entomology. During that time Denisha got the chance to do research studying the distribution of sheet-web spiders in vacant lots and community gardens throughout Cleveland, OH. The following summer Denisha continued on with research in entomology by gaining an internship at the University of Mississippi in Dr. Bradley Jones lab doing research on identifying glial cell markers in fruit flies. Denisha soon joined the ALE lab after graduating and is currently evaluating how urban land management influences the diversity, abundance and ecological function of predatory arthropod fauna.
Christopher B. Riley
Chris graduated summa cum laude from the University of Maryland in 2014 with a B.S. in Environmental Science & Policy and minors in Geographic Information Systems and Sustainability Studies. As an undergraduate, Chris conducted research in the lab of Dr. Michael Raupp where he spent much of his time studying the biology and ecology of the invasive brown marmorated stink bug. For his honors thesis, Chris examined the effects of continental origin on the susceptibility of woody plants to biotic and abiotic problems within residential landscapes. Chris joined the ALE Lab in 2014 and is conducting the bulk of his dissertation research within the vacant lot system in Cleveland, Ohio, where he hopes to further explore his interests in urban ecology and forestry, native/exotic plant-insect interactions, and sustainability. His research involves examining the ecological role and conservation value of native and exotic trees on vacant land in supporting biodiversity and promoting arthropod-mediated ecosystem services within spatially complex and heterogeneous urban environments.
