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?

🚨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.

Some birds are left behind in a race to beat the heat - Nature Ecology & Evolution

Twenty years of occurrence data for North American birds suggest that range shifts in some, but not all, bird species have partly mitigated the effects of climate change.

Trump vs. Birds: Proposed Budget Eliminates Critical Research Programs • The Revelator

Experts say there’s “no substitute” for the Bird Banding Laboratory or the Breeding Bird Survey, which help reveal the health and status of avian populations across the country.

What's the location?

Jeremy Cohen @drjerbs.bsky.social · Jun 10

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.

Jeremy Cohen @drjerbs.bsky.social · Jun 10

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

Jeremy Cohen @drjerbs.bsky.social · Jun 10

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).

Jeremy Cohen @drjerbs.bsky.social · Jun 10

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.

Jeremy Cohen @drjerbs.bsky.social · Jun 10

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.

Jeremy Cohen @drjerbs.bsky.social · Jun 10

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.

Jeremy Cohen @drjerbs.bsky.social · Jun 10

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.

Jeremy Cohen @drjerbs.bsky.social · Jun 10

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.

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

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.

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 👉

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!
