| 説明 | Behind the scenes pics of what you will see on Oregon Public Broadcasting’s Oregon Field Guide next fall:Frogs in the Dry Creek desert may sound like an oxymoron but here hundreds and perhaps thousands find an oasis in Eastern Oregon. Biologists recently spent a week catching and releasing spotted frogs. Think of it like going to the doctor's office for a check-up where you get weighed and measured. The one difference is biologists add a tracking Personal Identity (PI) tag behind the shoulders of each frog before sending it back to live several more years. Here, in Dry Creek, biologists have been studying spotted frogs for the past 12 years and have some interesting discoveries.
