The Incredible Hidden World of Arbuscular Mycorrhizal Fungi
Tuesday November 5, 2013 – 6:30 @ The New York Botanical Garden, in the Arthur and Janet Ross Lecture Hall
Presented by Renee Johansen – visiting Fulbright Scholar from New Zealand at Duke University
Fungal communities below ground can be highly complex and have substantial effects on the plants they interact with. New technologies are providing insights into the structure and function of arbuscular mycorrhizal fungal (AMF) communities, but much is still unknown. This talk will briefly explore the techniques available for studying these plant root symbionts and cover aspects of their ecology and biogeography. I will then present my PhD project, which will investigate the effects of plant host, season and biogeography on the community composition of arbuscular mycorrhizal fungi in coastal dunes. My pilot study has produced the first data on coastal AMF in New Zealand – around 32 taxa were found in a dune built by only one plant species, including taxa without sequences currently on Genbank (therefore possibly endemic) and others previously recorded from around the globe. Next generation sequencing of environmental samples now plays a fundamental role in such studies, and I will discuss a promising new approach currently in development using illumina multiplexing. This will enable researchers to obtain information from different gene regions of large numbers of samples simultaneously, using a common set of barcodes, improving our ability to understand the hidden world beneath our feet.
Bark: Get to Know Your Trees
Tuesday December 10, 2013 – 6:30 pm – @ The Central Park Arsenal
Presented by Michael Wojtech: freelance naturalist, writer, photographer, and illustrator
The traits typically used to describe trees—leaves, twigs, and buds—are often difficult to see or, in the case of leaves, absent more than half the year. Bark is always visible, in any season, but is often considered too complex for all but the most experienced observers. Through a presentation and hands-on exercises Michael will describe how bark physiology provides criteria for classifying specimens by bark type and for recognizing species-specific characteristics, which often change as trees mature. He will also review bark ecology—the functional advantages that have influenced bark’s wide array of appearances. Why do some species have smooth bark, while on others it is thick and broken? Why does bark peel? Some of the many human uses of bark will also be covered.
Signed copies of Michael’s book, Bark: A Field Guide to Trees of the Northeast, will be available. For more information visit: www.knowyourtrees.com.
