Where There is Water, There is Life! Exploring the endemic and cosmopolitan diatom species in the McMurdo Dry Valley, Antarctica using the MCM LTER database EARTH 2016 - New Brunswick, NJ Alia Thompson and Olivia Swanson Jern

Summary Microbes, specifically diatoms are not only abundant in all ecosystems on Earth but have a profound impact on the functioning of the Earth as a system. Understanding and identifying diatoms becomes important to determine the success of the ecosystem. Humans also have a profound impact on the environment by transporting alien species through tourism and scientific research expeditions. Students will be exploring what endemic and cosmopolitan species are on a local, regional and global scale using a variety of activities and technology. Students will also explore the positive and negative roles humans play in changing an ecosystem. On a global basis...the two great destroyers of biodiversity are, first habitat destruction and, second, invasion by exotic species. - E.O. Wilson
