Climate change is one of the top three global threats to seabirds, particularly species that visit polar regions. Arctic terns migrate between both polar regions annually and rely on productive marine areas to forage, on sea ice for rest and foraging, and prevailing winds during flight. Here, we report 21st-century trends in environmental variables affecting arctic terns at key locations along their Atlantic/Indian Ocean migratory flyway during the non-breeding seasons, identified through tracking data.

Many species of wading birds (Charadrii) are dependent upon intertidal sites to feed, but, as a result of anthropogenic pressures, the prey landscape has changed at many estuaries. Behavioral adaptations may be able to buffer these changes.

- Body size is crucial for understanding pollination ecology but is often difficult to measure; allometric scaling laws can help, but current models have limitations due to small sample sizes and geographic restrictions.
- Researchers measured body size in 391 bee species and 103 hoverfly species across four continents, using a Bayesian mixed-model framework to improve predictions of dry weight based on intertegular distance (ITD) and other factors.
- Findings showed that including additional variables improved interspecific size predictions, while ITD alone was inconsistent for predicting intraspecific body size; this research contributes to a new package for enhancing allometric studies in pollination.
