#Fieldwork yesterday & today yielded several highlights:

A dozen blue spotted #salamander #larvae , plus one dead in a trap (with a massive belastomatid insect [aka "toe biter"]).

These larvae are part of a student's project, which he'll be presenting @MWPARC this August! Image
Plus metamorphosing or recently metamorphosed #amphibians of a few different species! (It's that time of the year in central #Minnesota )

In some spots the ground was littered with tiny wood #frog (Lithobates sylvaticus) metamorphs. You can see this one's remaining tail nubbin. ImageImage
And right as I was reminding us to "keep an eye out for metamorphosing #toads" I came across this American toadlet (Anaxyrus americanus) Image
"Morphing out" can be difficult, and not everyone successfully makes it through the process and onto land.

This grey tree #frog (Hyla chrysoscelis/versicolor) was mid-process when it died. Image
To all the larval #salamanders and #frogs in ponds & wetlands out there:

Sally forth young'uns! And best of luck!

This is my first time teaching our new #online topics in #biology course for #masters students. Our focal theme this semester: #UrbanEcology & #urban #evolution.

We are on our 4th seminar & paper discussion (fascilitated by @perusall !) and some of the side-convos coming up are excellent! Like...

🏙️#CitizenScience: how to standardize, do it ethically, and communicate with the public?
(Prompted by nature.com/articles/s4200…)

2/4
🏙️#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? 🤔
(Prompted by: onlinelibrary.wiley.com/doi/abs/10.111…)

#BlackBirderWeek Day 2 is full of folks doing great #scicom & communication about what the #BlackInNature experience means.

Just a few highlights below!
#TIL during #BlackBirderWeek

1) Paleohistology is a really cool field! Check out @Yara_Haridy 's blog & short clip introducing #fossil remnants of #cells ()

Looking for an indoor #ecology game? Try this card game! Would be good for #STEMeducation at several levels Image
I played the single player game and went with these two #biomes first

#marine
Temperate #forest Image
Here’s the #marine biome I finished with Image

A thread on #ImageAnalysis & #color in animals:

#AcademicTwitter ,#Herpetology , & folks that analyze #color from images:

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)

It’s the time of year where I grade #HerpFall2019 field notebooks! Always fun to see how they remember things and express themselves.

Favorites below in thread
#herpetology #fieldwork
Some #HerpFall2019 students thought belastomatid #insects were “nightmare fuel” 😂

We caught a few of these aquatic predators in our minnow traps. They’ll absolutely eat #amphibians ImageImage
Whereas the #hognose #snake was a hit Image

Fun take on the #biology of the Demogorgon on #StrangerThings !

Demogorgons develop front limbs first. Interestingly, that’s how some #salamanders develop too!

1/4
#Salamanders in the family #Ambystoma (aka mole salamanders) develop their front limbs first as well!

Here is a young marbled salamander #larva showing off its front limbs & frilly external gills. Image
But for #frogs we see the back limbs developing first.

Cool #FrogFacts :

The back legs are visible as they develop on a #tadpole , but the front are hidden under a layer of skin (the operculum).

As the tadpole develops, they BURST out through the skin!

Aliens style 😉
