Intermittent downpours are not ideal weather for outdoor classes, unless your topic for the day is: salamanders!
So a hardy (and uncomplaining — YSR!) group of cyclists headed out in the rain, destination Shakerag Hollow. This is the first of many days of salamandering for my Advanced Ecology and Biodiversity class. We’ll be documenting the local fauna and comparing communities among streams with varying degrees of sedimentation.
The focal stream for the day yielded many Spotted Dusky Salamanders, Desmognathus conanti. These stocky animals are fast movers: you need quick hands to catch them. They are about five inches long and hide under rocks, emerging at night and in downpours to feed on insects and other small prey.
Spotted Duskies stake out a tiny stretch of stream for their home range, so we made sure to put them back exactly where we found them.
In addition to salamanders, we found several crayfish, including this one, expertly captured and held by my colleague David Johnson, that has two babies attached to the underside of its tail. The females usually carry eggs in this position, but youngsters generally swim off on their own.
The woods were also full of fungi, including this stinkhorn…
…and a spectacular growth of what I think is “chicken-of-the-woods,” a species that is edible (to some; for others it causes considerable distress). This fungus was visible from about fifty meters away. It glowed through the mist of the forest. No, it burned. But salamander-like, we survived the fire.
Learning ecology at Sewanee was truly an unparalleled experience and opportunity! So glad to see things haven’t changed :-)
Thank you, Marie! Great students are what make it happen.
Great finds, all! I had no idea about the crayfish eggs/babies being carried like that. We’ll have to start turning them over to look now.
Your duskies seem to be a lot more active than the burly spotted salamanders we found in the backyard in 2011: http://youtu.be/3xlIi-ql-4Q
Great video. An impressive salamander — hard to beat a spotted salamander for impressive heft. I wonder if the other one in the video is a northern redback?
Apparently, the first instar of crayfish larvae do sometimes remain on the mom.
re: the “other” salamander. Google searching seems to indicate that it very likely is a northern redback. Cool. Thanks!
