Recent reductions in thickness and extent have increased drift rates of Arctic sea ice. Increased ice drift could significantly affect the movements and the energy balance of polar bears ( Ursus maritimus ) which forage, nearly exclusively, on this substrate. We used radio‐tracking and ice drift data to quantify the influence of increased drift on bear movements, and we modeled the consequences for energy demands of adult fema...

We explored the interacting effects of marine‐derived nutrient fertilization and physical disturbance introduced by coastal river otters ( Lontra canadensis ) on the production and nutrient status of pristine shrub and tree communities in Prince William Sound, Alaska, USA. We compared production of trees and shrubs between latrines and non‐latrines, while accounting for otter site selection, by sampling areas on and off sites....
