Abstract Changes in phenology and distribution are being widely reported for many
migratory species in response to shifting environmental conditions. Understanding these …

Mechanisms governing the migratory decisions of birds have long fascinated ecologists and
sparked considerable debate. Identifying factors responsible for variation in migration …

Human behavior profoundly affects the natural world. Migratory birds are particularly
susceptible to adverse effects of human activities because the global networks of …

Background Understanding the evolution of migration requires knowledge of the patterns,
sources, and consequences of variation in migratory behaviour, a need exacerbated by the …

Worldwide, migratory phenology and movement of many bird species is shifting in response
to anthropogenic climate and habitat changes. However, due to variation among species …

Seasonal migrations are used by diverse animal taxa, yet the costs and benefits of migrating
have rarely been empirically examined. The aim of this study was to determine how …

Gulls commonly rely on human-generated waste as their primary food source, contributing to
the spread of antibiotic-resistant bacteria and their resistance genes, both locally and …

Anthropogenic change is impacting ecosystems globally, causing declines in biodiversity.
Long-distance migrants are particularly susceptible, as they depend on conditions over …

In migratory animals, the developmental period from inexperienced juveniles to breeding
adults could be a key life stage in shaping population migration patterns. Nevertheless, the …

Migrating animals show remarkable diversity in migration strategies, even between
individuals from the same population. Migrating longer distances is usually expected to be …
