Scouting with drones to increase efficiency of locating wild pigs for removal

open access: yesWildlife Society Bulletin, Volume 49, Issue 4, December 2025.
Our goal was to determine if locating wild pigs with thermal cameras mounted on unmanned aerial vehicle technology, drones, just prior to ground and aerial shooting efforts could increase removal rates of invasive wild pigs. Results suggest that scouting with drones can increase removal rates under a variety of conditions. Abstract Effective management

Predictions of southern migration timing in coastal sharks under future ocean warming

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Projected redistribution of marine species due to ocean warming may undermine current conservation efforts. Yet, there have been few studies on how ocean warming may alter migration timing. Across 5 years of acoustic telemetry data (2018–2022), we determined environmental drivers of southward migration timing for 6 migratory shark species from
