Invasive species are one main cause for the poor conditions in the Peconic river. Using DNA Barcoding we can identify new species that may/may not be invasive. Through the process of PCR (polymerase chain reaction) we can extract, amplify, and compare the DNA (from the CO1 genome) of our insect and crustacean species. Using these processes we can identify species and determine if they are known, a novel species, or a invasive species. Using this information we can target these invasive species and eliminate them before they cause more harm.
