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/...

We are turning Earth into a unlivable Hot House Earth Earth was about 2.65 degrees Fahrenheit (or about 1.47 degrees Celsius) warmer in 2024 than in the late 19th-century (1850-1900) preindustrial average. The 10 most recent years are the warmest on record. climate.nasa.gov/vital-signs/...

Trump vs. Birds: Proposed Budget Eliminates Critical Research Programs • The Revelator therevelator.org/trump-vs-bir...

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 👉

Last month's total #Arctic sea ice volume averaged the 3rd lowest on record for the month of November... Data using PIOMAS: psc.apl.uw.edu/research/pro... 🌊

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 🧪

Hello Bluesky, it's my first post, here's some Little Auks ! 🙂 #birding #northumberland #beadnell

American woodcock appreciation- hanging out by the side of a back road in central Connecticut in May #birds 🪶

Literally the best bird

Incredible job by my colleagues at Map of Life! advancing tech in biodiversity monitoring

Temperatures in October 2024: Red 🟥 - warmer than average Blue 🟦 - colder than average Data from NOAAGlobalTemp v6.0.0 using their own 1971-2000 baseline: www.ncei.noaa.gov/products/lan...

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

[Recapping research since I left Xitter: June '24] We explored how dynamic winter min temps influence short-distance migration & survival in white-tailed deer using decades of archival telemetry data 🧪 My first pub as a formal grad mentor- of an awesome MS student at UW-Madison shorturl.at/eUc7B

#birds of southern California earlier this year 🪶 roadrunner, avocet, threatened California gnatcatcher, endangered California condor

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...

I recently wrote up this research highlight of the nest parasite community science program run by @sarahknutie.bsky.social

[Recapping our research since I quit Xitter - Apr '24] Continental-scale experiment and global analysis show local amphibian-fungal interactions result in high pathogen prevalence, growth, and host mortality, but novel interactions led to some virulent combinations🧪 Led by @eronhubbard.bsky.social

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

Washington state #birds from a trip earlier this year 🪶 Varied thrush, American and Eurasian wigeons, Anna's hummingbird, Canada jay

[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 🧪

[May '24] Meta-analysis on global change drivers and the risk of infectious disease. Biodiversity loss, chemical pollution, climate change and introduced species are associated with increases in disease endpoints- consistent for human & non-human diseases. 🧪https://doi.org/10.1038/s41586-024-07380-6

Swiss and Italian #birds I photo'd this past summer 🪶

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
