The folks at the City of Austin’s Cimate CoLab have posted this guide to creating your own CoLab in your city.

We installed two Motus towers at our UTMSI/Fennessey Ranch field station last week. The Motus network tracks the movements of migratory birds. Radio receiver towers can detect transmitter tags attached to birds from as far as 20km away. As the number of birds carrying tags and the number of towers increase over time, the greater resolution we will have on the routes long-distance migratory birds use. This is especially important in identifying key stop-over locations where birds refuel before contining migration. These are the first MOTUS equipment installed as part of UT that we are aware of.

Funding was provided by the Texas Gulf Coast Research Center.

I have made my BioSense repository public on github. The BioSense software runs sdm inside of a docker and generates raspberry pi os images that can be burned to media and used to boot a raspberry pi. These images can be fully configured to connect to a wireguard vpn and begin recordding data. Services are provided to record sound, interogate a GPS, record environmental data off of a BME 280 sensor, manage a UPS (power up and down as needed), run BirdNet, and log soil moisture data. We currently have BioSense running on 8 devices in the field.

If you think BioSense could be useful for your project, please contact me. We are happy to collaborate and consult on projects. Note that I am rewriting BioSense at the moment, so a future version will have a cleaner and more automated design. Nonetheless, BioSense represents a considerable amount of development on my part and I hope will be useful to others and stimulate collaborations.

Super-student Nikunj Goel (now a postdoc with Mevin Hooten) has posted a preprint to bioR$\chi$iv. Nikunj has extended the theory of natural selection to include spatial sorting, a process in which dispersal-linked genes are disproportionately represented in newly colonized regions. The cool thing is that he developed the theory and used that to figure out what to measure. He found folks that had relevant data and closed the loop. A really impressive bit of theory-data integration. Check it out here.

Every time I need to use Fourier transforms in R, I have to relearn the layout and the relationship between the order of coefficients and their associated frequencies.

I decided to make things easier for myself by wrapping the Fourier coefficients, along with their frequencies, in a tibble for easy manipulation.

The result is the fftab package. You can also find it on CRAN.

Thanks to funding from the Southeastern Conference (Who said football was not good for something?), I had an ejoyable visit to the University of Florida in October 2024 hosted by my former postdoc advisor Bob Holt.
The timing was excellent as I got to see my pal, Ottar N. Bjørnstad, who was a postdoc at NCEAS and happened to in town, and former UT colleague Matthew Leibold.

I have been wanting to move to GitHub Pages and Jekyll for awhile. Now that the college is shutting down its site service, I finally got around to building the new site. I made two tries at using an existing Jekyll template called Academic Pages. It was quite helpful, yet it is designed for a single investigator, not a lab group. Once you start modifying the site extensively, the theme becomes more of a hassle than an asset. So I started fully from scratch an built my own pages, collections, and style sheets. It is not too bad once you get the hang of it. See if you can find the embedded pun.

Happy New Year!
