Vertical migration is a geographically and taxonomically widespread behaviour among
zooplankton that spans across diel and seasonal timescales. The shorter‐term diel vertical …

Global movement patterns of migratory birds illustrate their fascinating physical and
physiological abilities to cross continents and oceans. During their voyages, most birds land …

Bird migrations are impressive behavioral phenomena, representing complex
spatiotemporal strategies to balance costs of living while maximizing fitness. The field of bird …

Addressing important questions in animal ecology, physiology, and environmental science
often requires in situ information from wild animals. This difficulty is being overcome by …

Many animals keep track of their angular heading over time while navigating through their
environment. However, a neural-circuit architecture for computing heading has not been …

Light‐level geolocator tags use ambient light recordings to estimate the whereabouts of an
individual over the time it carried the device. Over the past decade, these tags have …

Migratory species depend on a suite of interconnected sites. Threats to unprotected links in
these chains of sites are driving rapid population declines of migrants around the world, yet …

Migration, broadly defined as directional movement to take advantage of spatially distributed
resources, is a dramatic behaviour and an important component of many life histories that …

Abstract Since the last Arctic Monitoring and Assessment Programme (AMAP) effort to
review biological effects of mercury (Hg) on Arctic biota in 2011 and 2018, there has been a …

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 …
