Greener cities are not only prettier, they’re healthier for residents and the environment. Trees and urban green space help cities save money on wastewater treatment, heating and cooling, hospital admissions, and even violent crime. We will explore the value of urban green space and the specific needs and efforts underway in Cleveland.
Ants are important seed dispersers, and these tiny champions often form very tight relationships with plants, especially forest herbs. Some plants even provide food resources specifically to attract their favorite ant mutualists. But, when invasive species or climate change come onto the scene, these close relationships are vulnerable to disruption. Both plant and ant invaders have the potential to impact native mutualisms, with potentially devastating consequences for communities. Prior will discuss her work characterizing these mutualisms and her research on best management practices of invaded ecosystems.
Stuart Pearl will present a slide talk on Cape Breton Nova Scotia, Canada’s National Park, where the mountains meet the sea. His lecture will focus on the geography and the harbors of this fascinating area as he hiked among the bogs, forests and rocky escarpments. Pearl seeks out interesting textures and patterns in his photographic compositions that will both engage and entertain the audience.
Lichens cover 8 percent of the world’s land surface, and have been described as “the fungi that discovered agriculture.” Join Adams for a photographic introduction to the fascinating Lilliputian world of lichens – what they are, where to find them, tips on lichen identification, and their use in air pollution monitoring, clothing dyes, and food for wildlife.
The biological diversity of the deciduous forests in eastern North America is threatened by habitat fragmentation, increasing homogeneity of the vegetation, and the loss of top predators. Understanding the history and ecology of deciduous forests is critical for sustaining productive forests and preventing the loss of biological diversity. Dr. Robert Askins will describe studies of remarkably similar forests in East Asia and Europe, which provide new insights about how to protect forests in North America.
