We glue transmitters onto their upper shells (called their carapace) using non-permanent epoxy. We will track these turtles until the transmitter battery dies (about 2 years) and soon after that the epoxy degrades, and the transmitter will fall off the turtle without harming the turtle or it's shell.

Turtle found in the spring coming out of brumation. It is still covered in mud from being buried in the ground all winter. They can brumate up to several months!

Northwestern pond turtles often return to the same area each winter for brumation. We tracked this turtle overwintering in almost the exact same area in the winters of 2023 and 2024. It's brumation location was only 11m apart between the two years.

Q: What’s the difference between PFOS and PFAS?
A: PFAS is a broad term that refers to a large group of man-made chemicals that contain fluorine atoms. This group includes thousands of different compounds and are highly resistant to degradation.

This turtle crossed a road leaving the reservoir and will cross it again to return to the reservoir. Road crossings present high risk to turtles and are a large source of mortality.

Boats and trailers can move invasive plants and animals between lakes. Aquatic invasive species are bad news and they need a plan for early detection and fast response.

Invasive swamp eel (Monopterus albus) collected in central Florida. Swamp eels are used as bait and in live food markets and have the potential to impact the ecology and economics of a waterbody.

RestoreNet is a networked ecological restoration experiment spanning drylands of the American Southwest. It is engaging diverse partners to develop methods for successful revegetation projects that mitigate the effects of drought, invasion by non-native species, and land use practices.
