Top‐Down and Bottom‐Up Processes Jointly Explain Mesopredator Movement and Foraging Ecology
Ecology Letters, Volume 29, Issue 3, March 2026.This study integrates top‐down (polar bear habitat selection) and bottom‐up (fish distribution) processes to test how mesopredators (ringed seals) balance risk–reward tradeoffs in habitat selection. Ringed seals reduced their space use and foraging time in response to predation risk, yet accepted higher risk when prey diversity was elevated ...

The Anatomical Record, Volume 309, Issue 2, Page 397-416, February 2026.Abstract Mysticetes, or baleen whales, have an air sac on the ventral surface of the larynx known as the “laryngeal sac.” The primary hypothesis regarding this structure's function is that it is involved in sound production. However, several other functions have been proposed, including air recycling, air storage, and even buoyancy control.
