There is compelling evidence that A fro‐P alaearctic (A‐P) migrant bird populations have
declined in E urope in recent decades, often to a greater degree than resident or short …

Light‐level geolocation data loggers, or geologgers, have recently been miniaturized to the
extent that they can be deployed on small songbirds, allowing us to determine many …

Endogenous programs that regulate annual cycles have been shown for many taxa,
including protists, arthropods, fish, mammals and birds. In migration biology, these programs …

Geolocator accuracy varies, depending on bird behavior, geographic location, habitat, and
weather (Fudickar et al. 2012, Lisovski et al. 2012). Ground truthing at multiple sites prior to …

Abstract From July 2018 to January 2019 we recorded 41 specimens of adult Hyalomma
ticks, which had been found on horses, cattle or humans in 14 Swedish provinces. In 20 …

Migratory birds regularly perform impressive long-distance flights, which are timed relative to
the anticipated environmental resources at destination areas that can be several thousand …

According to migration theory and several empirical studies, long‐distance migrants are
more time‐limited during spring migration and should therefore migrate faster in spring than …

Migratory connectivity is the degree to which populations are linked in space and time
across the annual cycle. Low connectivity indicates mixing of populations while high …

Animal movement patterns in space and time are a central aspect of animal ecology.
Remotely-sensed environmental indices can play a key role in understanding movement …

Properly timed spring migration enhances reproduction and survival. Climate change
requires organisms to respond to changes such as advanced spring phenology. Pied …
