Community‐driven variations in snow algae color modulate snow albedo reduction

New Phytologist, Volume 249, Issue 4, Page 1739-1752, February 2026.
Summary Snow algae blooms visibly alter snow color and surface energy balance, yet the biological basis of this variability remains unclear. We investigated how pigment composition and community structure shape the optical properties of snow algae blooms of distinct colors – red, orange, and green – co‐occurring within the same snowfield in Glacier ...

AVIRIS‐3 Rapid Response to January 2025 Los Angeles Wildfires

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Wildfires in wildland‐urban interfaces (WUIs) are a growing concern due to their devastating impact on human communities and ecosystems. Low‐latency impact assessment is critical for wildfire response, yet immediate access to fire‐affected communities can be limited.

Comparison of drone and ground surveys for the detection of a rare plant in a fragile ecosystem

Ecological Solutions and Evidence, Volume 7, Issue 1, January/March 2026.
We compared the accuracy, time, and financial costs of drone and ground surveys for the detection of wood lilies (Lilium philadelphicum) in an endangered alvar ecosystem. We found that the drone surveys detected 73%–78% of the plants found in the ground surveys, but that this type of survey was more expensive and time consuming than the ground survey ...
