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 …

Species extinctions have defined the global biodiversity crisis, but extinction begins with loss
in abundance of individuals that can result in compositional and functional changes of …

A common goal of biological adaptation planning is to identify and prioritize locations that
remain suitably cool during the summer. This implicitly devalues areas that are ephemerally …

The green-up of vegetation in spring brings a pulse of food resources that many animals
track during migration. However, green-up phenology is changing with climate change …

Identifying which ecological and life history traits influence a species' tolerance to
urbanization is critical to understanding the trajectory of biodiversity in an increasingly …

The Arctic is warming more rapidly than other region on the planet, and the northern Barents
Sea, including the Svalbard Archipelago, is experiencing the fastest temperature increases …

This paper advances an hypothesis that the primary adaptive driver of seasonal migration is
maintenance of site fidelity to familiar breeding locations. We argue that seasonal migration …

During seasonal changes around the globe, trillions of insects are on the move. Many insect
populations, including butterflies, moths, hoverflies, and dragonflies, make repeated …

Abstract Information on species' distributions, abundances, and how they change over time
is central to the study of the ecology and conservation of animal populations. This …
