Cool paper alert. Was trying to model the thermal performance curves of several farmed seaweed species and ran across this awesome, theoretical unifying paper: “A universal thermal performance curve arises in biology and ecology” www.pnas.org/doi/10.1073/...

Regional ecosystem responses to environmental drivers in cold‐water lakes evaluated using stable isotopes of salmonid fishes Diverse environmental drivers influence food web energy and nutrient flows, a key ecosystem function, yet their relative importance remains poorly known. We compiled thousands of bulk stable isotope ....

Thanks braddah! 9 months left in a fellowship I’m grateful to have, but we’ll see what happens. I’m afraid I’ll have too many ideas left unfulfilled

Got 3 postdocs pulled from me in the last year because of US funding… but getting to the point that I can’t keep waiting around for the next cycle to have less opportunities. Unfortunately it’s likely forcing me out of academia.

My co-authors and I are happy to present our framework "Collective Intelligence as Collective Information Processing (CIP)."

Here we propose decomposing different information processing mechanisms to unify disparate phenomena traditionally classified as "collective intelligence."

Huzzah! After a lot of work, I'm happy to share that the results of my first chapter have been published and are available for your perusal. In this paper, I was interested in understanding how characteristics of urban environments influence the diel activity of cats academic.oup.com/jue/article/...

Using the voter model from physics, we simulate networks with stubborn agents (zealots) who do not change their opinions, asking about their optimal positioning for influencing the network.

Nice! Did you use the spatialRF package for your random forest regressions? Would love to read but no institutional access 😢

So delighted to have worked with Drs Christine France and Julianne Sarancha on this project. With deer samples, we created isoscapes (Sr, O, and S) for the state of Virginia.
Potentially hella useful for archaeology in the region. 🏺🧪 www.tandfonline.com/doi/full/10....
