Comparing Two Non-Invasive Methods For Assessing Marine Mammal Genetic Diversity: Environmental Dna Vs. Fecal Dna, Sydney Jackson

Honors College

As technology and science progresses, the methodology behind observing, monitoring, and sampling marine mammals advances as well. One such technique is environmental DNA or eDNA, which entails extracting organismal DNA from water samples without ever handling or disturbing the organism. It is a cost-efficient and non-invasive method that can be utilized in the sampling of seal haulout sites as is its purpose for this research. Another method, using the DNA analysis of seal fecal samples, is a less invasive method that can also be utilized to monitor and assess marine mammals. Through collecting both fecal and water samples from gray …
