Bumping this up one last time. I'm looking to hire graduate student(s) to work on an NSF-funded project to study elevational range shifts among dragonflies here in Colorado. @cudenverclas.bsky.social 🧪🌍🐙

Applications will be considered until Nov 1. See post below for more details

new paper from my lab @cudenverclas.bsky.social in @natclimate.nature.com, led by @sarahnalley.bsky.social!

Dragonflies with dark mating ornaments on their wings are disappearing from parts of the United States that have had more warming and wildfire over the last 40 years 🧪🌍🐙

Big news! We are recruiting a postdoc to work on tomatillo evolution: jobs.colorado.edu/jobs/JobDeta.... The clade containing tomatillos and its allies (ca 300 spp) has evolved lantern fruits at least 25 times - we want to know why! Join us @rociodeanna.bsky.social & @caschenck-bio.bsky.social

I'm so excited to share my master's research! Do pollinators change their foraging behavior depending on floral and ambient temperatures? Do flowers that thermoregulate experience higher rates of pollinator visitation? Check it out below! 🏵️

New preprint out today! A really fun collaboration with @shchurch.bsky.social and Robin Hopkins in which we study flower color variation in Monarda fistulosa using iNaturalist data. We process >40,000 images and use them to phenotype flower color in >16,000 observations: doi.org/10.1101/2025...
Figure 1: Steps with representative photographs of the flower color phenotyping pipeline. A) We exported all research-grade iNaturalist observations of Monarda fistulosa from GBIF. B) We used GPT-4o to classify each image as to whether it contained a flower. C) We trained a Roboflow semantic segmentation model on a subset of images and applied the trained model to extract “flower” pixels from each image in the dataset. D) We calculated the geometric median of each set of extracted pixels to represent the flower color phenotype from each image, and we paired this phenotype with the observation’s iNaturalist metadata for spatial analysis. Figure 2: Spatial summary of Monarda fistulosa flower colors across North America. A) Map of the color of M. fistulosa flowers. Each square is a 200km x 200km cell with the color corresponding to the average median CIELAB color value of each observation in the cell. The dotted line denotes -100° longitude, separating eastern and western regions of the range. B) Boxplots summarizing LCh color components west and east of -100° longitude, with each box showing the median and interquartile range, and with the color of each box reflecting the geometric median CIELAB value from west and east, respectively.

🚨Report your NSF grant terminations! 🚨

We are starting to collect information on NSF grant terminations to create a shared resource as we have for NIH. The more information we collect, the more we can organize, advocate, and fight back! Please share widely!

airtable.com/appGKlSVeXni...
NSF Grant Termination Information Collection Form Please use this form to submit information identifying specific NSF grants that have been cancelled for any reason after January 20, 2025. We are tracking these grants to increase transparency, organize affected PIs, and facilitate responses, including via litigation. Please share the form as widely as possible with your networks. We are actively building a pipeline to organize these terminations and will soon have a tracker akin to our NIH grant tracker at https://airtable.com/appjhyo9NTvJLocRy/shrNto1NNp9eJlgpA WE WILL NOT DISCLOSE THE IDENTITY OF ANYONE WHO USES THIS FORM TO PROVIDE INFORMATION. We will keep your identity confidential. These resources are maintained by Noam Ross of rOpenSci and Scott Delaney of the Harvard T.H. Chan School of Public Health, with input and support from additional volunteers. For any questions, please contact Scott Delaney on Signal (sdelaney.84). THANK YOU FOR YOUR ASSISTANCE!

Hot off the presses and so so thrilled. Thanks to @inaturalist.bsky.social + computer vision we found something beautifully simple: Red and orange flowers bloom later than all the other colors in the eastern United States. Paper here: authors.elsevier.com/a/1kwzh3QW8S...
Visual abstract: “we test hypotheses about floral diversity with community science data and an advanced computer vision model. Red/orange flowers have delayed flowering that matches hummingbird migratory patterns”

Just extended the deadline to March 21 for this position in the Plant Phylogenomics group at the University of Vienna. It is sort of a "post doc plus" position funded for up to six years.

Please reach out if you want to chat - I'd love to talk to you about it!

If you’re a Visa cardholder you can let them know you won’t be any longer if they do business with fElon. I called and they said they’re taking comments at askvisa@visa.com. Maybe if enough of us complain they’ll pull the deal.
