Imperiled Species Detection and Monitoring

It is difficult to evaluate the presence or abundance of many imperiled species. Low numbers, cryptic behaviors or habitats that are difficult to search can combine to make it difficult for a researcher to detect and monitor species and population changes.  Wildlife and Fisheries researchers are applying research tools from molecular science to attempt to better understand and evaluate these species.  If there is sufficient DNA from the species of interest in the environment, it may be possible that through application of these techniques the animal can be detected. This can include use of environmental DNA (eDNA) to detect the presence in water for imperiled freshwater mussels or fish.  Sequencing of scat or stomach contents can be another means to detect imperiled species when they become prey for native or invasive species.
