This #FrogFriday I netted up some beautiful gray tree #frog#tadpoles (Hyla chrysoscelis or versicolor) and this gorgeous northern leopard frog (Lithobates pipiens) from a small, boggy wetland. 1/n
I also chased (and consistently missed) several mink #frogs (Lithobates septentrionalis). These crafty ranids are said to have a foul, onion-y smell, so I was bummed not to get one in hand. Something to look forward to for the next #FrogFriday in #Minnesota ! 2/n
Although it was #FrogFriday , there were other critters out and about, too. Including a pair of Sandhill Cranes (Grus canadensis) and a few turtles (this one is a painted #turtle [Chrysemys picta]). 3/3

🏙️#Sex biases in the individuals studied in the lab & field. Why is it more often males of a species? What data are we missing because of that bias? 🤔

Any recommendations for ways to collect data about color & pattern from images of #wildlife? We want to quantify things like %cover by a color & intensity.
Have enjoyed reading some of the work by Davis & Grayson on quantifying #color, hue, % coverage in #newts and other animals.
They used Fovea Pro, a Photoshop add in. The newer version (QIA-64) costs ~$800 😬
Am also considering the methods of Paterson & Blouin-Demers where they quantify continuous variation in throat color in #lizards using Adobe & ultimately analysis in #imageJ (but haven't had time to test it out yet)
