Lanique Dawson and her partner will collect algal samples along the Hudson River starting from Battery Park towards Inwood Park. They want to study whether human interaction affects algal diversity in metropolises by determining the types of algal species found using DNA barcoding (Saunders and McDevitt, 2013). In metropolises extensive heat is produced because of the Urban Heat Island effect, which causes plant growth rates to double compared to rural areas (Greg, 2003). They want to observe temperature affects from site to site. They will use DNA barcoding to compare the biodiversity of algae between sites.
