We report the first satellite tracking of natal dispersal by an Arctic fox (Vulpes lagopus)
between continents and High-Arctic ecosystems. A young female left Spitsbergen (Svalbard …

Background Biologging now allows detailed recording of animal movement, thus informing
behavioural ecology in ways unthinkable just a few years ago. In particular, combining GPS …

The Arctic tundra has a relatively low biodiversity but species living there have unique
adaptations and are exposed to unprecedented rates of climate warming. Monitoring …

Fluxes of matter, energy and information over space and time contribute to ecosystems'
functioning and stability. The meta‐ecosystem framework addresses the dynamics of …

Climate change has different and sometimes divergent effects on terrestrial and marine food
webs, and in coastal ecosystems, these effects are tightly interlinked. Responses of …

Long-distance dispersal plays a key role in species distribution and persistence. However,
its movement metrics and ecological implications may differ whether it is undertaken by …

Little is known about potential cascading effects of climate change on the ability of predators
to exploit mobile aggregations of prey with a spatiotemporal distribution largely determined …

Rapid range expansion of boreal forest predators onto the tundra may disrupt local
ecological processes, notably through competition with ecologically similar species. Red …

As top or mesopredators, carnivores play a key role in food webs. Their survival and
reproduction are usually thought to be influenced by prey availability. However …

Indirect interactions are widespread among prey species that share a common predator, but
the underlying mechanisms driving these interactions are often unclear, and our ability to …
