Lecture/Field Trip with Rikke Næsborg
Lichens are found in almost every habitat on all kinds of surfaces around the world, but since they are often small and somewhat inconspicuous, they are frequently overlooked. That is a pity because lichens are extraordinary and complex organisms. Not only are lichens little ecosystems that consist of a symbiotic association between at least one fungus and at least one alga; lichens also play significant roles in the ecosystem from colonization and stabilization to contribution to the nutrient cycle. Lichens have been used for centuries by humans as dyes, medicines, and food. More recently a range of new uses have been employed such as monitoring air pollution. California hosts over 2000 lichen species, spanning a fantastic array of colors and shapes. This talk will explore the fascinating and amazing world of lichens.
Rikke Reese Næsborg, Ph.D., is the first Tucker Lichenologist and Curator of the Lichenarium at Santa Barbara Botanic Garden. Rikke earned her bachelor’s and master’s degrees at University of Southern Denmark and went on to earn a doctorate in systematic botany from Uppsala University in Sweden.
