Do you like amphibians? Do you like science? Well then, you've come to the right place! Enjoying clicking around and learning about yellow-legged frogs, the research I'm currently working on, and keep up with what I'm doing in the field!


      The detection of species using environmental DNA (eDNA) is newer technique that is growing in application for non-invasive survey of species [1]. Environmental DNA is genetic material from environmental substrates, like soil or water, which can be collected and used to detect presence without handling or capturing the species of interest. This is particularly useful for endangered or rare and hard to find species that may be disturbed or missed during traditional survey methods. Thus, it can be useful for species conservation. Environmental DNA can be captured from water that is pumped through a filter or spun down and pelletized [2].
