A semi-regular description of what’s going on at the drift fences on the Savannah River Site. Most will refer to Rainbow Bay--an isolated wetland completely encircled by a drift fence with pitfall traps. The Rainbow Bay fence has been “run” every day since September of 1978! We'll also talk about all types of fieldwork occurring at the Carolina Bays and other wetlands on site.

Camel crickets everywhere
I got to escape the lab and head to Rainbow Bay today to help check buckets and release some of the 200 or so marbled salamanders that were caught leaving the bay the other day. We had about 16mm of rain the other night so a bunch of males (and one female) decided it was time to leave the bay. The males leave before the females----males leave after the mating season is over, but females will continue to stick around and protect their nests for a while. If we don't get a lot of rain soon even they will eventually give up and leave their nests. Previous research by major bay runner David Scott has shown that the nests do not do as well without female attendance, but he also showed that females are not eating during this time. So basically if the rains don't come to fill the bay and stimulate the eggs to hatch, the females eventually have to give up and go. It's raining a little right now, not enough to do much, but may have more males taking off tomorrow and I'll be curious to see if females start to go soon. As usual, even though the bay is dry the buckets were full of invertebrates. Today seemed to be camel cricket day. They were in a lot of the buckets. You can see they have huge "thighs," a humped back, and harder to see, really long antennae. I think they're pretty cool, most people come across them in their basements and don't seem to think so, but they don't chirp so it's not like they can be considered annoying. Though I even enjoy the chirping cricket in the basement.
