Exploring Marine Mammal Cognition as a Conservation Tool

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Cognition is an animal's real‐time adaptation system for responding to change. Rapid environmental change, often anthropogenic, is expanding the range and severity of challenges confronting wild animals. Effective conservation requires a multifaceted approach that includes animals' capacities.

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

Wildlife 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

Conservation 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

The biology behind the counts: tooth development related to age estimation in beluga (Delphinapterus leucas)

NAMMCO Scientific Publications, 2014
The widely accepted method of determining ages of beluga is to count dentine growth layer groups (GLGs) in median, longitudinal sections of a tooth. It is essential to understand how these growth layers form and to consider developmental factors that can
