I work at a public library. People who want to use AI seem to have no trouble doing so. People who don't want to use AI have a harder time. I crowdsourced and then finalized this document "How to disable or avoid intrusive AI" and then gave it a short URL: notoai.org Please pass along if it's useful

An aircraft passenger oxygen mask: a drop down passenger mask with air bag and yellow plastic mouth and nose cover, oxygen tube has been cut; Demonstration model used by flight attendant crew for passenger instruction. Has text on the side indicating that it's non-functional.

In our Viewpoint (onlinelibrary.wiley.com/doi/abs/10.1...) we synthesize the gametic definition (outlined by Janicke et al below) and other definitions of sex (e.g., multivariate definition). We contend that is NO consensus on “biological sex” (maybe a consensus isn’t actually necessary…)

There is No Consensus on Biological Sex

At this critical moment when misinformation about sex is being applied to policy globally, scientific clarification on the definition of biological sex is valuable. Here, we evaluate the primary appr...

In a new #Viewpoint we argue that the binary definition of #BiologicalSex based on gamete size is a scientifically robust framework that is entirely compatible with the diversity of sexual phenotypes and human gender identities. onlinelibrary.wiley.com/doi/10.1111/...

I am incredibly thrilled to announce that I will be starting as an Assistant Prof at Yale EEB in January 2027!! 🎉🎊 Stay tuned for student and postdoc openings, and please feel free to reach out to me if you are interested in eco-evo, range dynamics, species interactions, and global change! 🌐🌱🦠🧬

For years I've tracked billionaire excess. Each year I show students a chart that blows their minds. This year I had to redraw it for a trillionaire: Elon Musk, $1.32T. Depressing that we're here. Silver lining: couldn't have happened to a less deserving person, proof that wealth ≠ merit.

Elon Musk's $1.32 Trillion, to Scale

The first trillionaire's fortune, one pixel per $1,000 — scroll past every dollar, and see what a fraction of it could do instead.

New paper out today in Ecology Letters! We use Modern Coexistence Theory and Metabolic Theory to get general predictions for the effect of temperature on competition. Led by brilliant postdoc @kaleighedavis.bsky.social and @joeybernhardt.bsky.social, with Po-Ju Ke, Patrick Thompson and Mary O'Connor

General Predictions for the Effects of Warming on Competition

We combined two major theories in ecology to investigate whether warming may have general effects on competition for shared resources. We found that species' niche and fitness differences both decrea...

Been waiting for someone to write a paper on expectations of how warming impacts Lotka-Volterra-type competition! A great example of how revisiting a classic derivation (consumer resource -> Lotka-Volterra competition) with slight modifications can yield interesting findings. Excited to read it :D .

Excited to share our new paper in which we test how competition alters adaptation at a warming range edge @science.org We find that competition can increase adaptation to warming when there is a shared evolutionary response to both biotic and abiotic drivers of selection: tinyurl.com/3j8s9t8b

Competition enables rapid adaptation to a warming range edge in a model plant community

Most predictions of whether populations will adapt to warming range edges ignore species interactions. We experimentally tested whether range-edge populations can adapt to warming within a competitive...

Canada’s ‘major projects’ should not come at the cost of the environment

Excited to share our new paper: Predictions from evolutionary theory for urban environments. We brought together empiricists and mathematical theorists to find common ground on where and how we can work together to better understand urban evolution onlinelibrary.wiley.com/doi/abs/10.1...

Predictions From Evolutionary Theory for Urban Environments

Urbanization drives rapid and extreme environmental change, profoundly shaping the ecology and evolution of populations. In this Perspective, we call for the integration and development of evolutiona...

Great write up of research on the effect of temperature on range expansion rate by former undergrad in the lab Kayley Breslin! 🪲🔥

As the climate warms, animals are being forced to shift their ranges to survive.🐾 Research led by Kayley Breslin & tessgrainger.bsky.social @integrativebiology.bsky.social using beetles found warmer temperatures can accelerate both movement & population growth. www.uoguelph.ca/cbs/news/202...

The Bernhardt Lab is heading to #CSEE2026 and we are excited to share our science! From Ontario to Nunavut and theoretical ecology, data synthesis and experiments, to community-based research - we study how biodiversity is changing and what that means for human well-being. Check out our talks! 🌡️🐟🦎🌎

So proud of Dr. Asia Kaiser for her ESA Murray F. Buell Award & recently defending her PhD! Asia is an outstanding scientist & seeking a postdoc (urban ecology, insect biodiversity, bees, agroecosystems, & synthetic control/stat methods). Please connect w Asia w opportunities. Please boost! 🐝🌎🧪🥒🏙️🌱
