Second dissertation chapter just dropped at Ecology Letters! doi.org/10.1111/ele.70441 Across theory, stochastic models, and protist microcosms, we show how rising temporal autocorrelation drives predictable increases in extinction risk under warming (ft. coauthor @mtkummel.bsky.social!)

I am recruiting a PhD student interested in the disease ecology of cavity nesting birds to start Fall 2027! Interested applicants can contact me by filling out the linked form. I will also be at ESA 2026 and am happy to meet! More info on my website: sauerlab.com Please share!

I'm joining Rutgers DEENR in a tenure-track faculty position this fall! I'll be recruiting a quantitative postdoc in climate change wildlife ecology (start fall 26 or jan 27) and PhD student doing bioacoustics to study avian responses to extreme weather (start fall 27). More- www.gcmelab.com/join-us

We have a new perspective piece out about incorporating extreme heat in ecological research - academic.oup.com/icb/advance-...

🚨Now out! For 98 hummingbird species, we jointly model presence-only GBIF data + presence-absence ebird data, leveraging both simultaneously to arrive at more accurate predictions for under-surveyed species. And got the cover! Led by Jussi Mäkinen 🧪🌐 onlinelibrary.wiley.com/doi/full/10....

Exciting to be a part of this!

Thrilled to share our new paper out in @science.org, led by François Leroy and Petr Keil! Using the Breeding Bird Survey, we document not only a continent-wide decline in bird abundance since the 1980s — but, crucially, the acceleration of these declines over time. www.science.org/doi/10.1126/...

Leading a organized session at #WBF2026 on climate change and biodiversity! Titled "Linking anthropogenic climate change to shifting biodiversity patterns". If submitting an abstract, you can send it directly to the session (under NEX track)! worldbiodiversityforum.org

🚨Now out in @pnas.org! Our group provides a framework to mathematically link environmental niches from individual to population and species scales. Our approach enables more accurate forecasting of biodiversity change across organismal levels. 🧪 www.pnas.org/doi/10.1073/...

Nature Ecology & Evolution highlights our paper about bird niches keeping pace with climate change in a news & views feature: www.nature.com/articles/s41...

NEW SCIENCE! 🚨🚨🚨🧪🪶🌐 Our paper is now online at @natecoevo.nature.com! “Geographic redistributions are insufficient to mitigate exposure to climate change in North American birds”. We know birds are moving north with climate change, but what are the consequences? www.nature.com/articles/s41...

A high lipid diet leads to worse infectious disease outcomes. Interesting implications for wildlife food supplementation. Always exciting to have a new manuscript out! Congrats @ashley-love.bsky.social @sauerscientist.bsky.social @jexpbiol.Bsky.social journals.biologists.com/jeb/article/...

To understand how climate change affects natural ecosystems we need to know how warming influences species interactions. In our newest paper we show that predator-prey interactions fundamentally change across latitude leading to context dependent effects of warming. 🧪 doi.org/10.1111/oik....

The #climate/water paradox: As temperatures rise, more #water evaporates into the atmosphere & more precipitation occurs. But land areas are getting drier not wetter. Why? Because more water evaporates from soils. The rain that falls is in intense events in fewer regions, leading to worse #floods 👉

Just had an idea

‼️📝 New paper! 1st undergrad honor thesis from the lab! Hannah Owen looked at thousands of #spottedlanternfly @inaturalist.bsky.social images to study spatio-temporal & phenology patterns of the invasion, and to understand the role of #urban environments in their spread www.nyu.edu/about/news-p...

Saw/heard 104 bird species in Florida over Thanksgiving... crossing 100 was a goal I slowly become obsessed with, made tougher with all the best spots being closed due to hurricane. Here's a prairie warbler ebird.org/tripreport/2... 🪶 #birds

Wait, do I want cool science to drown out all of the politics?! Yes. Yes, I do. 🧪

Recently discovered a fun webpage called Probability Playground where you can interactively explore probability distributions. It’s helpful especially for distributions with parameters that are not immediately intuitive. Very cool! www.acsu.buffalo.edu/~adamcunn/pr...

🚨 NOW ONLINE- global ecol & biogeog As global change accelerates, accurate predictions are critical to limit biodiversity loss. With many continental predictions at coarse grain, it's unclear how grain-size biases vary across space/time, giving poor predictions for some regions, seasons, species 🧪

100s of millions of sparrows and other birds died. In the absence of birds, insects flourished; crops vanished; and as many as 75 million people starved to death. How does that disaster echo in what is happening today, even in the US? Read on: therevelator.org/china-sparro.... #birds

well, here it is lads after combing through some 1,400 records, it looks like the slender-billed curlew is indeed extinct and the last known photo taken in 1995 was probably at the point it slipped beneath the waves 🦉🧪 www.nhm.ac.uk/discover/new...

Climate change is a 'natural' process now occurring ~10 times faster than the average rate after an ice age. Extinction is 'natural' but is now occurring 1000X faster than in past eras (apart from mass extinctions). Biological invasion is now at rates 100000X prehistoric levels of spp colonisations.

No, it’s not just you. As a product of the Great Lakes region (Youngstown → SE MI → Lansing → Columbus → Cincinnati → Lansing → Cincinnati), the patterns, temperatures, and rhythms of the season feel unmistakably altered. Graphic via @climatecentral.bsky.social #climatesky #energysky

[My research recap: June '24]: The presence of fixed geographical survey locations (eg eBird hotspots) reduces the opportunistic nature of citizen science data, allowing for more reliable trend estimation. We estimated the survey completeness of richness at 300,500 eBird hotspots during 2002–2022 🧪

Take a read of this excellent paper - possibly the largest assessment of fire-biodiversity relationships ever conducted. How did the 2019-2020 Australian bushfires affect biodiversity?

Recapping research I published since I've been off Xitter! [Jan '24] Across 57 US waterbird species, at coarse grain, continuous landcover variables are much more informative for SDMs than binary variables- but this advantage disappears in fine grain models. doi.org/10.1007/s10980-024-01813-3

Recapping some research I published since I've been off Xitter! [Dec '23] Responses of wildlife to climate change are often quantified to species, but are we missing important variation below the species level over space (ranges) and time (seasons)? A macro approach! doi.org/10.1098/rspb.2023.1398
