Attending the Unifying Ecology Across Scales GRC was one of the highlights of my PhD, and this year's edition is going to be excellent! All biologists interested in integrating diverse approaches to further our understanding of the natural world are welcome. Register early! shorturl.at/rIjWx
A great conference to go to this summer – who could oppose unifying ecology on multiple scales?
I just finished attending a great conference (Island Biogeography Society), which reminded me how fun and intellectually stimulating a really good conference is. So here’s my recommendation f…

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.

www.nature.com/immersive/d4...
This line graph illustrates the percentage change in agency staff levels from the previous year for nine major U.S. federal scientific and health organizations between the fiscal years 2016 and 2025. The agencies tracked include the CDC, Department of Energy, EPA, FDA, NASA, NIH, NIST, NOAA, and NSF. For the majority of the timeline between 2016 and 2023, the agencies show relatively stable fluctuations, generally staying within a range of +5% to -5% change per year. However, there is a dramatic and uniform plummet starting in the 2024–25 period. Every agency depicted shows a sharp downward trajectory, with staffing losses ranging from approximately -15% to over -25%. The Environmental Protection Agency (EPA) shows the most significant decline, dropping to roughly -26%, while the National Institute of Standards and Technology (NIST) shows the least severe but still substantial drop at approximately -15%.

In winter, when deciduous trees are bare, we can really appreciate the form of a tree. Here is a chinkapin oak, Quercus muehlenbergii, on a ridgetop in Nashville. It is now surrounded by young forest, but you can tell by its branch pattern that it grew in an open woodland pasture.

I still remember when Istanbul had weeks of snow (yes, Istanbul!). When summers over 30°C felt alarming. When droughts and fires along the Aegean coast were exceptional enough to dominate the news for days. We normalize too quickly!

The extremely anomalous & in most cases record-breaking Nov-Dec warmth led to record-low snowpack in many areas. Heavy precipitation bolstered high elevation snowpack in some areas in late Dec despite warmth, but most basins remain far below average snow water equivalent.
Current NRCS map depicting present snow water equivalent (SWE) across the western U.S. The vast majority of basins are below average, many well below average, except for the central/southern Sierra and northern Rockies.

Carbon dioxide (CO₂) averaged about 427 ppm in December 2025

10 years ago December averaged about 402 ppm

Data available at gml.noaa.gov/ccgg/trends/
Red line graph time series of monthly carbon dioxide abundance from January 1959 through December 2025. There is a seasonal cycle and long-term increasing trend. Current levels of CO2 are at 427 ppm. This is the Keeling Curve graph. A line for CO2 10 years ago is also annotated.
