As tropical treelines are less studied than arctic, sub-arctic, and temperate elevational treelines, we hope this study illuminates the need for further attention to climate change mediated mountain ecosystem dynamics in the tropics.
We assessed the effect of spatial variables and distance to coast on treeline structure (change in treeline elevation) and function (change in treeline NDVI), revealing that treelines are moving up and becoming more dense, with the most rapid change in low latitudes.
We used remote sensing to assess patterns of treeline dynamics in 115 high mountain peaks across western North and Central America, from Costa Rica to Canada.
Mountain treelines have moved upward 20.2 m on average since the 1980s; this upward shift is more pronounced in the tropics than in temperate regions: bg.copernicus.org/articles/22/...

I'm so relieved to see that the science writing community has come out in force to support @thexylom.com in its hour of need. I'm proud to be part of a community that values the vital work that @alexip718.com & colleagues are doing. Nonprofit public service journalism is HARD & so very necessary.
Time to adopt SI Units like the rest of the world!
Check out this article by Kim Beil on recent work from Town Peterson, Anahí Quezada, Jeff Munroe, and I. We use the power of photography to track mountain treeline movement due to climate change: www.nytimes.com/2025/03/05/t...
I had the actual best time today hanging out with the Boyle lab and meeting K-State ornithology students!
Are you a PhD student whose funding is in jeopardy because of recent executive actions, or a faculty member in a program dealing with these considerations? @mkhaw.bsky.social and I want to hear from you @chronicle.com. DM or email! #AcademicSky #PhDSky #HigherEd
Grad student funding - Apply for the ASN Student Research Awards. $2k each for research that advances the conceptual unification of ecology, evolution, or behavior. Applications due March 14 www.amnat.org/announcement...
Has anyone taught or taken a good evolutionary ecology class? Any textbook recommendations are welcome!
“There have been alarming declines this year in some insect species including bees, butterflies, moths and wasps, while many #seabirds have also been “hammered” by unstable weather patterns caused by the climate emergency, the National Trust has said.”

The porphyrins in Northern Saw-whet Owl feathers glow under UV light. They degrade over time, so older feathers glow less intensely than new feathers. This bird has a clear molt limit between old juvenile feathers and new basic feathers, meaning she was born last summer!
#ComSciCon24 day one! @jocori.bsky.social
It was so cool spontaneously getting to help the Red-tailed hawk project for an afternoon of trapping 🤩
It’s always a pleasure to get to ramble about birds. I had so much fun participating in the Collections up Close series for the KU Natural History Museum with @anoplogaster.bsky.social and Kevin Mulcahey!
Overall, our findings suggest that nest orientation most likely controls the rate of change in the microclimate, rather than the microclimate itself. Most significantly, nest orientation affects the timing of morning warming in the hot summer breeding season. (5/5)
We faced previously collected pairs of Grasshopper Sparrow and Eastern Meadowlark nests in different directions during the summer of 2019. This allowed us to compare nest temperature, humidity, and wind speed within and among pairs. (4/5)
We noticed Grasshopper Sparrow and Eastern Meadowlark nest orientation differed between drought and non-drought years. These species build domed nests in the grass, so their entrances face a certain direction. (3/5)
Here is the paper for anyone interested: journal.afonet.org/vol95/iss1/a...
New publication with Alice Boyle and @inkliizii.bsky.social is out! This work is the first project I have completed as a scientist, and I am so excited to share!
We found experimental support for the idea that nest orientation is, in part, a regulatory mechanism for nest microclimate. 🧵(1/5)
