Quantifying environment–morphology relationships is important not only for understanding
the fundamental processes driving phenotypic diversity within and among species but also …

Background To understand the ecology of long-distance migrant bird species, it is necessary
to study their full annual cycle, including migratory routes and stopovers. This is especially …

Over the past decades, tracking technologies have become more ubiquitous and helped
uncover crucial spatiotemporal relationships in nature. In order to apply these technologies …

Climate change is leading to the advancement of spring conditions, resulting in an earlier
snowmelt and green‐up, with highest rates of change in highly seasonal environments …

Biodiversity monitoring has entered an era of 'big data', exemplified by a near‐continuous
collection of sounds, images, chemical and other signals from organisms in diverse …

Light‐level geolocators have revolutionised the study of animal behaviour. However, lacking
spatial precision, their usage has been primary targeted towards the analysis of large‐scale …

Mountain birds face numerous challenges caused by altitude‐dependent environmental
seasonality. Although elevation gradients may affect bird morphology, migration strategy …

Knowing the location of migratory birds throughout their annual cycle is fundamental for
many questions in ornithology. Technological advances have provided several approaches …

Species-and population-specific responses to their environment may depend to a large
extent on the spatial variation in life-history traits and in demographic processes of local …

Background Small songbirds respond and adapt to various geographical barriers during
their annual migration. Global flyways reveal the diverse migration strategies in response to …
