Alan Weakley is a plant taxonomist, community ecologist, and conservationist specializing in the Southeastern United States. He holds a B.A. from UNC-Chapel Hill and a Ph.D. from Duke University. He has worked as botanist and ecologist for the N.C. Natural Heritage Program, and as regional and chief ecologist for The Nature Conservancy and NatureServe. He is currently Director of the University of North Carolina Herbarium, a department of the N.C. Botanical Garden, and teaches as adjunct faculty at UNC-Chapel Hill and at the Highlands Biological Station.

Dr. Weakly is author of the Flora of the Southeastern and Mid-Atlantic States, and co-author (with Chris Ludwig and Johnny Townsend) of the Flora of Virginia, which has received five awards, including the Thomas Jefferson Award for Conservation.

Review of Naming Nature, by Carol Kaesuk Yoon

Reviewed by Michael Reinemer

In the midst of an accelerating mass extinction where we are losing species much faster than science can identify them, this is an engrossing look at taxonomy, or how we organize life on earth.

Yoon laments our disconnects from nature. A child living among the Indigenous Tzeltal Maya people in Mexico can identify about 100 different plant species, Yoon says. How many American adults can do that?

She provides an account of “folk” taxonomies that are binominal, two-word descriptors the predate Carl Linnaeus, the botanical whiz kid from Sweden who published Systema Naturae in 1735. That system laid out the framework that most of us learned, the Linnaean hierarchy — kingdom, phylum, class, order, family, genus, species. (Of course, we use that every time we select an unadulterated native plant for our garden, relying on the scientific name — genus and species — rather than a vague or even misleading common or commercial name. Don’t we?)

Later schools of thought refined how we might arrange living things. Well into the 20th century, “cladists” organized the tree of life around the branches (clades) based on evolutionary relationships. They famously declared that, technically, fish don’t exist. Lungfish, they would explain, are more closely related to cows than they are to salmon. That news would have been nonsensical to Linnaeus, and perhaps blasphemous to Izaak Walton. Walton described his 17th century meditation on conservation, The Compleat Angler, as a “Discourse of Fish and Fishing.” In any case, the cladists’ fish-dissing were fightin’ words to other taxonomists. With breezy, engaging insights, Yoon chronicles the debates.

The Secret of Species

The Clifton Institute, 6712 Blantyre Road, Warrenton, VA, 20187

Thursday, Jan 16, 2020

7:00pm – 8:00pm

When we hear about scientific discoveries, conservation breakthroughs, or just what’s been seen in the area recently, the stories are usually about species. “New species discovered!” “Endangered species need our help!” “I saw 20 species last weekend!” We hear and talk about species all the time, but we don’t usually stop to think about what a species is. In this presentation, Managing Director Eleanor Harris, Ph.D., will discuss what it means to be a species, why they’re so important, and how they have evolved. Throughout the talk she will focus on local examples, for example, why we distinguish Alder and Willow Flycatchers, but not red-spotted purples and white admirals.
