Scientist Lecture

Delve deeper into the issues and conditions that impact the world around us. These academic lectures allow you to step back into the classroom and learn from the experts.

Lectures are $5 for members and $15 for nonmembers. All programs are held at 7pm.

City Life in a Nutshell: How Organisms are Coping with Urbanization

Urban development is becoming more and more common throughout the globe, with over 50 percent of the world’s population living in some form of urbanized environment. This conversion of land from forests to cities is warming the environment above and beyond what forest-dwelling organisms would normally encounter. Species respond in diverse ways to warming, yet we know little about how populations in urbanized habitats cope with rapid environmental changes. Chick will show examples of how organisms in Cleveland — specifically, ants living inside acorns — have adapted to life in the city.

Getting By With a Little Help From Our FriendsSoil Microbes and Their Important Role in Plant Conservation

David Burke

No individual travels through this world alone; we are all covered by microscopic organisms that affect our health, growth and survival. Although traditional microbiology has focused on bacteria or fungi that cause diseases, there is an increasing appreciation for the “friendly” microbes that live on or within other organisms and comprise what has come to be called the microbiome. In plant ecology, these “friendly” microbes help plants acquire nutrients and resist disease. Mycorrhizal fungi, which are a particular group of soil fungi that live on plant roots, may be especially important for the survival of plant species, the composition of plant communities, and potentially for resource “sharing” among plants. If the first rule of intelligent conservation is to save all the parts, we need a better understanding of the plant microbiome and friendly mycorrhizal fungi if we are to successfully save plant species in a changing world. This talk will explore what we know, and what we don’t know about the plant microbiome, and how cutting edge techniques are opening up a whole new frontier in plant ecology.

Dr. Michael Donovan, Cleveland Museum of Natural History

Recovery of Plant-Insect Associations in the Wake of the Dinosaur Extinction

This lecture is being presented as part of the Bio-alliance, a collaboration between Holden Forests & Gardens, Case Western Reserve University, the Cleveland Museum of Natural History and the Cleveland Metroparks Zoo. The Bio-alliance was formed in April 2019 to promote local opportunities and resources, to create transformative educational experiences, and to inspire inter-institutional research in biodiversity, ecology and evolutionary biology across the premier biological research institutes of Northeast Ohio.
