Temporal variation characterizes many of Earth's ecosystems. Despite this, little is known
about how food webs respond to regular variation in time, such as occurs broadly with …

By depicting who eats whom, food webs offer descriptions of how grou**s in nature
(typically species or populations) are linked to each other. For asking questions on how food …

The cumulative effects of climate warming on herbivore vital rates and population dynamics
are hard to predict, given that the expected effects differ between seasons. In the Arctic …

Arctic wildlife is often presented as being highly at risk in the face of current climate warming.
We use the long-term (up to 24 years) monitoring records available on Bylot Island in the …

Sympatric species are expected to minimize competition by partitioning resources,
especially when these are limited. Herbivores inhabiting the High Arctic in winter are a prime …

Broad scale population estimates of declining species are desired for conservation efforts.
However, for many secretive species including large carnivores, such estimates are often …

It has been hypothesized that climate warming will allow southern species to advance north
and invade northern ecosystems. We review the changes in the Swedish mammal and bird …

Lemmings are a key component of tundra food webs and changes in their dynamics can
affect the whole ecosystem. We present a comprehensive overview of lemming monitoring …

How food webs are structured has major implications for their stability and dynamics. While
poorly studied to date, arctic food webs are commonly assumed to be simple in structure …

Significant progress has been made in our understanding of species-level responses to
climate change, but upscaling to entire ecosystems remains a challenge,. This task is …
