Mineral dust particles are transported through the atmosphere from the world’s deserts, deposited over the oceans, and affect climate and global warming in many different ways. Changing winds and rain determine how much and how far dust is transported, but the exact relations and feedbacks between dust and climate are unclear. Dust from the Sahara Desert that blows over the Atlantic Ocean will be collected, its particle size, shape and composition will be studied, and climate models will reveal how dust and climate affect each other. This knowledge is fundamental to make more accurate predictions for our future climate.

The Arctic warming advances snowmelt and arthropod emergence, affecting breeding phenology of shorebirds. However, mismatches between predator and prey phenology threaten chick growth and survival. This PhD project examines if birds adjust behaviorally to mitigate mismatches. Arctic tundra heterogeneity may offer localized arthropod peaks post-general peak, potentially aiding predators. Sanderlings in northeast Greenland are studied for movement patterns, chick growth, and diet changes. Three expeditions collected data analyzed for 2019 and 2021. DNA-metabarcoding analyzes droppings. Research reveals mechanisms to counteract Arctic warmings effects, crucially. Results will be published soon, contributing to understanding trophic mismatches in birds.
