Adult survival has a stronger role than productivity in the annual population change of European songbirds Open
Biodiversity is decreasing at an alarming rate, and there is an urgent need to understand the demographic drivers behind population declines. Therefore, it is important to study the different stages of a species’ life cycle, including adul…

Human contributions to global soundscapes are less predictable than the acoustic rhythms of wildlife Open
Across the world, human (anthropophonic) sounds add to sounds of biological (biophonic) and geophysical (geophonic) origin, with human contributions including both speech and technophony (sounds of technological devices). To characterize s…

How Do Synchrony in Survival and Productivity Influence Abundance Synchrony in European Landbirds? Open
Synchronous fluctuations in species' abundance are influenced by synchrony in underlying rates of productivity and survival. However, it remains unclear how rate synchrony varies in space and time, contributes to abundance synchrony, and d…

Climatic Predictors of Long‐Distance Migratory Birds Breeding Productivity Across Europe Open
Aim Ongoing climate changes represent a major determinant of demographic processes in many organisms worldwide. Birds, and especially long‐distance migrants, are particularly sensitive to such changes. To better understand these impacts on…

A hybrid population of Willow Warblers in the Åland Archipelago Open
Differences in migratory behavior have been suggested to drive speciation, but the genetics underlying this process remain unknown. Identification and study of migratory divides can help us understand how differential migration can lead to…

Winter locations of red‐throated divers from geolocation and feather isotope signatures Open
Migratory species have geographically separate distributions during their annual cycle, and these areas can vary between populations and individuals. This can lead to differential stress levels being experienced across a species range. Gat…

Snow depth drives habitat selection by overwintering birds in built‐up areas, farmlands and forests Open
Aim Abundances of animals vary according to species‐specific habitat selection, but habitats are undergoing rapid change in response to anthropogenic alterations of land use and climate. The long‐term decline of snowfall is one of the most…
