In the Field with US Geological Survey’s amphibian monitoring program: Songmeters and Hydrophones in action
In this instalment of In the Field, we’re taking a peek at the research of Patrick Kleeman and Gary Fellers of the US Geological Survey.
WHERE: Primarily in Pt. Reyes and Yosemite National Park
WHY: They are looking for possible causes of the decline of amphibian populations in Northern California. The study is intended to be a long-term look at how breeding periods may change over time, possibly due to changes in climate.
