Do Stands Of Native Trees Harbor Different Invasive Species Than Stands Of Planted Pine?, Carly Mccameron, John Mccarthy, Dr. Kevin Geedey

The most outstanding invasive species that can be found at Augustana’s Green Wing Environmental Laboratory are honeysuckle, buckthorn, multiflora rose, garlic mustard, autumn olive, and oriental bittersweet. These plants are not only disrupting the ecosystem at Green Wing, but they are doing it all over the country. The result of their disruption is that they have taken over entire habitats and left natural species with no way to compete for survival. To study this we used the line-point method as well as other forms of data collection to compare a non-native pine tree habitat to an area dominated by native …

Genetic Sequencing For Measuring Biodiversity In Recent And Ancient Marine Sediments, Lauren Judge
Celebration of Learning
Taxonomic biodiversity, measured by counting the number of species present in a given area, is the most common method of capturing ecosystem biodiversity in recent and ancient environments. While this method is widely accepted, it is limited by poor preservation and identification of many individuals, making it impossible to include every species within an ecosystem and resulting in the loss of some diversity information. To address this issue, we measured the genetic biodiversity (in which species are determined based on sequencing of their DNA) of shallow marine ecosystems by extracting and sequencing the 18S ribosomal gene from bulk carbonate sediment …
