Does anyone know what this furry black lichen is? #FNHMe

A highlight from yesterday’s #FNHMe field lab: doll’s eyes, aka baneberry! The whole plant is toxic, especially the eyes—it can cause instant cardiac arrest.

They have the chance to go to natural history lectures, write mini-papers, do field scavenger hunts, or make Twitter or Instagram posts (#FNHMe) for flexible make-up points if they miss class or lab, or want to boost their journal, discussion, or final project grades.

One of my Field Natural History undergraduates made this awesome video on winter trees. Check it out! https://www.youtube.com/watch?v=9dhZlAlxTQ8 #fnhme

I'm enjoying grading the #FNHMe final projects. Check out this website a student developed for our local bog! http://mikeyt01.wixsite.com/thebogguide

#fnhme students, check out #ReignTheSwamp with cool tweets about wetlands! Feel free to add a few bog tweets.

Dragonfly nymphs live 4-6 years in water, then climb a rock and emerge as dragonflies. This is older one's wings are folded inside. #fnhme

This island in the Penobscot is made of the rounded edges of logs from an old mill; they silted in and trees grew. #fnhme

I counted 180 growth rings on this freshwater mussel. These are one of the most endangered groups on the planet! #fnhme

The #fnhme students are meeting freshwater invertebrates. First up: an urban bend in the Penobscot.

Two sea caves in @AcadiaNPS, past and present. Top: #fnhme students 250 ft up Gorham Mtn. Bottom: Anemone Cave. Why did sea level drop here?

Map lichen (Rhizocarpon geographicum), named for the shapes it makes (see the black outlines?) on Acadia's iconic Cadillac granite. #fnhme

Seaweeds aren't plants per se. They don't have roots, but they do have attachment structures known as "holdfasts." #fnhme

I love the pixelated color changes on this maple leaf! #fnhme

Pop quiz! How many species of algae can you see in this photo? #fnhme

Whose feather am I? #fnhme

Headed to @AcadiaNPS with the #fnhme students! It's a fun logistical challenge, because we have to pay attention to tides.

@JMcL14? #fnhme

This is why Latin names are important! My #fnhme students will appreciate this.

What made these mysterious holes? I bet my #fnhme students know!

Scouting Field's Pond for #fnhme lab tomorrow, and found the remnants of someone's lunch. Guess who?

An amusing video for my #FNHMe students as they study for their midterm (and David Attenborough name drops Linneus): https://www.youtube.com/shared?ci=BV8EFViwx9U

Thanks to @aBugBlog for telling #fnhme all about triops! We're all inspired to buy some.

Raccoon tracks on the banks of Pushaw stream. They were eating freshwater mussels. #FNHMe

Today's guest naturalist is @Fishy_Hayes, talking about southeastern streams. #fnhme

Red pitcher plants haven't had a bug meal in a while; their contents are clear. Brown water came from a green plant; smells of death! #fnhme

Witch's broom, a rampant growth form induced by excess auxin stimulated by a pathogen. #fnhme
