Alex & I both saw our first wood #frog egg masses yesterday! He spotted this group of eggs. They aren't too far along in development (I need to review dev timing papers to figure out approx age), and we didn't see eggs in other ponds where we heard choruses of frogs.
A close up of one clutch of wood #frog eggs (taken underwater).
We're headed out later today to check the traps we set in what we hope 🤞 are blue-spotted #salamander ponds.
Some studies indicate glow sticks improve trapping efficacy for mole salamanders, so we're giving that a try.
This is our first project targeting blue-spotted #salamanders , and my first #spring in the midwest, so there is going to be a #fieldwork learning curve.
Along with eggs that I think are blue-spotted #salamander eggs (from a 2nd pond).
This single egg was spotted by Alex (might have to nickname him eagle eyes), and we found about 4 others also laid among the submerged grasses.
Just in time for Easter, we also spotted new wood frog eggs and what I believe were boreal chorus #frog egg masses.
I think this is another chorus #frog egg mass, but it was larger and had more eggs than the others we saw. Though didn't seem large enough or spherical enough to be a wood frog egg mass.
🏙️#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)
