This good looking male (see the swollen cloacal region posterior to hind legs) was caught at a pond where we had previously found eggs but not adults.
Things I have learned:
- I'm still agile in chest waders 💪
- Blue-spots will lay eggs that are individually attached to vegetation/leaf litter (rather than in clumps, which is what I'm used to with other species of #Ambystoma#salamanders )
🤞that we have luck in a week or so with tiger #salamanders & their eggs! If anyone has photos of tiger sal eggs in situ, we'd appreciate seeing them!
🏙️#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)
