It seems the GRFP solicitation is FINALLY released (like 5 minutes ago)! Due dates have also been pushed back, thankfully! 🧪 🔭 www.nsf.gov/funding/oppo...

🐦 Never got around to posting about our paper on Gray Vireo #migration in @wilsonornithsoc.bsky.social (1 of my MS chapters), but better late than never! We used light-level geolocators to track migration ecology of ♀ and ♂ Gray Vireos from 3 breeding sites in New Mexico and Utah USA… 👇 short🧵 1/

Please share with anyone who cares about NSF support for graduate students and take 30 seconds to sign and leave a comment. The deadline for the 2025 Graduate Research Fellowship Program is about one month away and literally no one can apply. #NSFGRFP jasonjwilliamsny.github.io/grfp2025/

They’re not as close to my heart as birds, but one of the things that makes deer mice cool is that we can work with them in the lab and the field. Here we show how important doing both of those things is to accurately characterizing deer mouse trait evolution. Super excited to have this one out!

Late to the party, but I'm so excited about the first paper from our lab: ✨Unique genetic bases of repeated life-history divergence associated with high altitude adaptation in Mimulus perennials ✨ This work was led by the ABSOLUTE ROCKSTAR Hongfei Chen!

Did some mandatory gen AI training. Unfortunately, I was given an opportunity to provide feedback.

Are animals randomly distributed in the air, or is there a structure to where and when we find them? In our new paper we outline factors that shape habitat use in the air, from abiotic structure to biotic interactions. A lot of fun discussions behind this one! 🦅🦋🦇🌬 www.cell.com/trends/ecolo...

"In a landmark study, OpenAI researchers reveal that large language models will always produce plausible but false outputs, even with perfect data, due to fundamental statistical and computational limits." www.computerworld.com/article/4059...

This is the fourth Belted Kingfisher that has hit windows on the @umassamherst.bsky.social campus since July 2024… Two classes (Population Ecology and Global Change Ecology) are conducting daily surveys of 21 buildings to document these collisions this semester.

Come work with us… PDRA position to work on a host of exciting things! jobs.exeter.ac.uk/hrpr_webrecr... Get in touch if you want to know more

Direct human actions such as hunting and bird deterrence at aquaculture sites kill up to 10% of the populations of some shorebird species migrating along China’s coast each year, suggesting that this direct mortality is an overlooked threat to migratory populations 🧪 www.nature.com/articles/s41...

New research estimates that U.S. cuts to TB programs could cost as many as 2.2 million additional lives by the end of the decade. Even short-term disruptions could cost tens of thousands. www.npr.org/sections/goa...

The BLM is seeking to eradicate the Public Lands Rule, which allows the conservation to be included in land use planning. There are a lot of areas of critical environmental concern in BLM land. It's in the federal register and the public commenting period has started. Please comment!

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 🧪🌍🐙 rdcu.be/eFm7e

Extreme climate events can catalyze rapid evolutionary change! in our new Current Biology (@currentbiology.bsky.social) piece, Colin and I argue it’s time to study their evolutionary consequences systematically — beyond opportunistic observations. www.cell.com/current-biol...

Some asked if we had a ‘beef’ with Efrat et al. — quite the contrary! Their elegant work merited a proper response, so we wrote a letter to share our view on their work and long-standing Qs about migration counts. If the khachapuri doesn't get to us first, we still fit together through one door! 😁

Do you like acoustic data, community ecology, and desert oases? Apply for a PhD in my lab to investigate the role of ephemeral water sources (i.e., playa lakes and tinajas) in structuring desert bat (and maybe bird) communities. Visit lavertylab.org/join-the-lab for more. Applications due October 1

We have a new paper developing methods for looking at bird-fire macroecology. What’s most fascinating to me is that the magnitude *and* direction of fire effects can vary enormously across a species range. Stationarity is dead!! Long live non-stationarity!! doi.org/10.1002/fee....

First pop gen paper from our lab! We find repeated evolutionary turn over of sex chromosomes in darters contributes to reproductive isolation. Turnover may be an escape hatch to resolve mitonuclear conflict & neo sex chromosomes evolved via a rare recessive mutation. www.biorxiv.org/content/10.1...

One of the best parts of tracking birds is getting reports of those birds from far away. Thus, it was so cool to learn that not one, but two of the Willet our Mass Audubon-led team tagged in Massachusetts in June were seen in Barbados!

Incredible review on the recent dramatic changes we're seeing around Antarctica. A fact I found personally impactful: "Antarctic winter sea-ice loss over the past decade is of similar magnitude to the total Arctic winter sea-ice loss over the past 46 years" www.nature.com/articles/s41...

Super proud of @meaghansaurus.bsky.social and all the effort this study represents in the field (led by Eric Hileman & Jen Moore!) and in the lab. Worrisome story for the snakes, but important to know, learn from & act on.
