Showy dragonflies are being driven extinct by warming and wildfire
Year: 2025
Rising temperatures may disrupt reproduction before becoming lethal; thus mating traits could define species vulnerability to warming. Here, using >1,600 estimates of local extinction for 60 dragonfly species, we show that species with mating-associated wing ornamentation experienced more extinctions and lost more habitat under warming and following wildfire burn than non-ornamented species. By contrast, sensitivity was not affected by ecological traits, such as thermal limits, habitat specialization or body size.

Geolces: Geospatial Support for Evaluating Wildland Firefighter Lookouts, Communications, Escape Routes, and Safety Zones
Year: 2025
Wildland firefighters play a critical role in managing the complex relationship between humans and fire. To reduce the inherent risks that come with this role, firefighters use safety protocols such as lookouts, communications, escape routes, and safety zones (LCES). Currently, LCES implementation is conducted on the ground with limited support from geospatial information, despite the protocol’s inherently spatial nature. This study introduces GeoLCES: an analytical framework designed to enhance LCES implementation using remote sensing and geospatial modeling. GeoLCES comprises three…
