Tuesday Crustie: The river of woe

Surface dwellers, meet Cherax acherontis. Cherax acherontis, meet surface dwerllers.


There are plenty of burrowing crayfish in Australia, but this crayfish from the island of New Guinea is the first cave dweller, not just in the region, but south of the equator. That's quite remarkable, considering that the Pacific is a hotspot of crayfish biodiversity, and there are southern hemisphere crayfish in Madagascar and South America.

The name is from Acheron, one of the rivers the ran through the underworld of Greek mythology.

Twice in a lifetime: South Texas snowfall!

Last time, I only saw the aftermath.

This time, I got to see it happen.


Snow!


There hadn’t been snow in a century before 2004, and now twice in less than 20 years? This is crazy.


It started around 9:00 am, and ran for a couple of hours. It was big fluffy flakes that was coming down quite thick at one point.


I asked everyone I saw, “Are we having fun yet?!” Everyone was having fun. Everyone was happy. One student said, “This is the best thing that could have happened during finals!”


There were snowball fights outside the library.


Alas, it dod not last long. After a couple of hours, it had stopped. But there was so much snow on the trees, that as it melted, it sounded like a downpour.


Last time, I made a snowman. This time, I made something different:


A South Texas snow angel!

I can’t believe I got to see snow twice in South Texas during my time there. Today was pretty magical.

I’ve been inside for an hour now, and my fingers are still numb.

End of a project


Eight years ago and three months ago, I started a project to accommodate Jessica Murph’s request to do fieldwork (she was a student in the NSF REU program I ran then). It was a simple project to try to figure out some basic biology of the local sand crab species, Lepidopa benedicti.

Jessica finished her year in the program, and I kept going. And going.

Along the way, the project yielded three papers (Murph and Faulkes 2013, Faulkes 2014, 2017). The last paper covered up this project from 2011 to the end of 2015, and I have gathered two more years of data, making it seven calendar years of continuous monthly samples.

It’s a project where I genuinely felt I learned a lot. There was, at the start of this project, very little known about any species of this family. This project was a good first step in understanding the natural history not just of L. benedicti, but the family. And I found a species that had never been documented in the area before.

There were times when things got crazy when I could just think to myself, “I have to go to the beach.” They were good opportunities to decompress.

That project came to a close for the foreseeable future yesterday.

Posting here has been slow this semester, because I stuff that I didn’t want to blog about. It’s good stuff, not bad! I have some big plans that start early next year that I am very excited about.

But for every door that opens, one closes. These projects will be taking me away from South Texas, and I’m not going to be able to visit my field site for a while. I can’t go collect and measure “my” sand crabs.

I’ve had other projects that have ended before, but I can’t think of another that ran so long. It’s tough knowing that I still have questions that I will only be able to answer by collecting, and not knowing if or when I might be able to pick up the project again. Even if I do, I won’t have the bragging rights of a nice, continuous record.

On the plus side, I do still have two more years of field data in the can that I can analyze. I hope that I might be able to squeeze one more paper out of this project.

But I’m still a little sad.
