Model‐Based Data Integration Improves Species Distribution Models for Data‐Deficient and Narrow‐Ranged Hummingbird Species Aim For species with narrow ranges or low population sizes, a deficiency of species occurrence records can limit the capacity to build accurate species distribution models (SDMs). Model-based integr...

🚨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....

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/...

🚨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.

What's the location?

Species’ historical niches are becoming increasingly mismatched with contemporary climates even in a highly mobile taxon like birds, raising concerns about the ability of other wildlife to persist in a warmer world. Other wildlife may have to rely on phenological or behavioral changes.

We found similar results when repeating these analyses using eBird alone or Breeding Bird Survey data, highlighting the robustness of the findings.

Species possessing traits associated with dispersal, such as long-distance migratory behavior or high hand-wing index, succeeded most in limiting their niche loss (partial residual plots).

Species moving the furthest north succeeded most in limiting their niche loss. Move north, avoid warming. However, only very few species moved north far enough to fully erase their exposure, and in most cases they only partially limited their exposure.

Therefore- species averted much more of their expected exposure in summer, when they are more at risk of physiological consequences of heat stress- but still only avoided half of the expected warming in this season.

Most redistributions were only partially effective. Species moved their ranges ~0.65° latitude north in both seasons, mitigating their expected exposure by ~1.28 °C in summer (48% of expected if they were stationary), while only mitigating ~0.47 °C (11% of expected) in winter.

We developed a method to account for biases in tens of millions of species observations from GBIF and evaluate how 406 bird species native to the US and Canada have mitigated their environmental niche loss using geographical redistributions from 2000-2020.

As climate change accelerates, species can move poleward (north, in North America) or up mountains to limit their exposure to heat. While these movements have been extensively reported, it remains unclear whether species have succeeded in limiting their exposure to novel conditions.

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?

A high-lipid diet leads to greater pathology and lower tolerance during infection Summary: Canaries fed a diet high in lipids show more severe disease outcomes than those fed a high-protein diet, with important implications for human and wildlife disease transmission.

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

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. 🧪

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 👉

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. 🧪

Yep. One of the most feeder friendly birds in the Eastern US. Usually one of the first species to find the feeder

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!
