Food web structure in temporally-forced ecosystems
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 …

Herbivores in Arctic ecosystems: effects of climate change and implications for carbon and nutrient cycling
Arctic terrestrial herbivores influence tundra carbon and nutrient dynamics through their
consumption of resources, waste production, and habitat‐modifying behaviors. The strength …

Contrasting effects of summer and winter warming on body mass explain population dynamics in a food‐limited Arctic herbivore
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 …

Documenting lemming population change in the Arctic: Can we detect trends?
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 …

Estimating large carnivore populations at global scale based on spatial predictions of density and distribution – Application to the jaguar (Panthera onca)
Broad scale population estimates of declining species are desired for conservation efforts.
However, for many secretive species including large carnivores, such estimates are often …

Highly overlap** winter diet in two sympatric lemming species revealed by DNA metabarcoding
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 …

Long-term monitoring at multiple trophic levels suggests heterogeneity in responses to climate change in the Canadian Arctic tundra
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 …

A boreal invasion in response to climate change? Range shifts and community effects in the borderland between forest and tundra
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 …

The use of DNA barcodes in food web construction—terrestrial and aquatic ecologists unite!
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 …

Exposing the structure of an Arctic food web
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 …
