"Chasing Butterflies: Endemic Butterflies of the Spring Mountain Range" is the topic of a talk by Daniel Thompson, professor in the UNLV School of Life Sciences, and Paula Garrett, research scientist with the UNLV Public Lands Institute, a unit of the Division of Educational Outreach. The presentation is part of the College of Liberal Arts University Forum Lecture Series and will take place 7:30-8:30pm on Sep. 25 in the auditorium of the Marjorie Barrick Museum on the UNLV Main Campus. The Spring Mountain Range is considered a “sky island” due to its bio-geographic isolation from other mountain ranges of similar elevation. The highest point of the range is Mount Charleston peak. Surrounded on all sides by the Mohave Desert, the Spring Mountains provide the only remaining refuge to a variety of endemic species. These include a number of rare butterflies existing nowhere else in the world. The impact of the Carpenter Canyon Fire in July also will be discussed. The lecture is free and open to the public.
