Soaring over open waters: horizontal winds provide lift to soaring migrants in weak thermal conditionsMovement Ecology - Tập 11 - Trang 1-12 - 2023

For soaring birds, the ability to benefit from variable airflow dynamics is crucial, especially while crossing natural barriers such as vast water bodies during migration. Soaring birds also take advantage of warm rising air, so-called thermals, that allow birds to ascend passively to higher altitudes with reduced energy costs. Although it is well known that soaring migrants generally benefit from...... hiện toàn bộ
Timing is critical: consequences of asynchronous migration for the performance and destination of a long-distance migrantMovement Ecology - Tập 10 - Trang 1-16 - 2022

Migration phenology is shifting for many long-distance migrants due to global climate change, however the timing and duration of migration may influence the environmental conditions individuals encounter, with potential fitness consequences. Species with asynchronous migrations, i.e., with variability in migration timing, provide an excellent opportunity to investigate how of the conditions indivi...... hiện toàn bộ
Foraging behavior links climate variability and reproduction in North Pacific albatrossesMovement Ecology - - 2015

Climate-driven environmental change in the North Pacific has been well documented, with marked effects on the habitat and foraging behavior of marine predators. However, the mechanistic linkages connecting climate-driven changes in behavior to predator populations are not well understood. We evaluated the effects of climate-driven environmental variability on the reproductive success and foraging ...... hiện toàn bộ
Juvenile Steller sea lion (Eumetopias jubatus) utilization distributions in the Gulf of AlaskaMovement Ecology - Tập 6 - Trang 1-15 - 2018
Amanda Bishop, Casey Brown, Michael Rehberg, Leigh Torres, Markus Horning
A utilization distribution quantifies the temporal and spatial probability of space use for individuals or populations. These patterns in movement arise from individuals’ internal state and from their response to the external environment, and thus can provide insights for assessing factors associated with the management of threatened populations. The Western Distinct Population Segment of the Stel...... hiện toàn bộ
Context drives movement patterns in a mobile marine predatorMovement Ecology - Tập 11 - Trang 1-15 - 2023

Intra-specific variability in movement behaviour occurs in all major taxonomic groups. Despite its common occurrence and ecological consequences, individual variability is often overlooked. As a result, there is a persistent gap in knowledge about drivers of intra-specific variability in movement and its role in fulfilling life history requirements. We apply a context-focused approach to bull shar...... hiện toàn bộ
