The temporal dynamics of most tundra food webs are shaped by the cyclic population dynamics of lemmings. While processes during winter may be behind the recent disruptions of lemming cycles, lemming winter ecology is poorly known. We present here the first DNA metabarcoding data on the winter diet of Norwegian lemmings (Lemmus lemmus), based on feces collected after a winter of population increase. Prostrate willows, mosses, and graminoids dominated the species winter diet, indicating that the… 
The menu varies with metabarcoding practices: A case study with the bat Plecotus auritus
A critical evaluation of several data treatments on the inferred diet of the bat Plecotus auritus using guano regularly collected from various colonies throughout the entire active season indicates that DNA extracted from large amounts of fecal material issued from guano accumulates yield broader taxonomic diversity of prey than smaller numbers of pellets would do.
Spatial distribution in Norwegian lemming Lemmus lemmus in relation to the phase of the cycle
It is believed that the distribution patterns observed during the increase phase show a stronger ecological signal for habitat preference and that the less specific habitat use during the peak phase is a result of lemmings grazing themselves out of the best habitat as the population grows.
Trophic Interactions between Snow Goose and Brant Goose in the Breeding Time with Regard to Their Population Trends
Abstract —This paper studies the differences in the trophic resource use in the breeding time between the snow goose Anser caerulescens that is the most abundant in the Arctic and the most widespread
Response of vegetation and carbon fluxes to brown lemming herbivory in Northern Alaska
Abstract. The Arctic is warming at double the average global rate, affecting the carbon cycle of tundra ecosystems. Most research on carbon fluxes from Arctic tundra ecosystems has focused on abiotic

The critical agenda for mammalian ecologists over this century is to obtain a synthetic and predictive understanding of the factors that limit the distribution and abundance of mammals on Earth.
Using subnivean cameras to compare winter habitat occupancy of lemmings and voles in an arctic small rodent community
To understand the effect of rapidly changing winter climate on arctic tundra ecosystems, small rodents constitute a key indicator. Their population density cycles are very sensitive to changing
Recent literature on bryophytes — 121(4)
The isolation of a peptidyl prolyl isomerase FKBP12 gene (PaFKBP12) from P. alpinum collected in the Antarctic and its functional implications in development and stress responses in plants are reported.
Population cycles and outbreaks of small rodents: ten essential questions we still need to solve
This overview focuses on the most important issues that are essential for understanding the generality of small rodent population dynamics and highlights ten questions directly related to the various characteristics of relevant populations and ecosystems that still need to be answered.


Shedding new light on the diet of Norwegian lemmings: DNA metabarcoding of stomach content
It is suggested that there may be substantial variation between habitats and regions in lemming diet, as previously used microhistological methods result in large proportions of poorly resolved plant taxa.
Will the Norwegian Lemming Become Endangered If Climate Becomes Warmer
The Norwegian lemming, Lemmus lemmus (L.), the only endemic vertebrate species in Fennoscandia, normally lives in alpine tundra habitats. During population peaks wandering lemmings may settle in
Habitat Use and Diet Composition of Norwegian Lemmings and Field Voles in Central Norway
This study examined habitat use and diet composition of Norwegian lemmings and field voles, which occur together and potentially compete for resources in alpine areas of central Norway, finding a clear preference for monocots in their diet.
It is argued that the assumption of logistic growth of the food supply may be appropriate for only a few species, such as moss-eating lemmings, and the dynamics of food supply for many arvicoline (microtine) rodents may be better described by a “linear initial regrowth” model, which exhibits globally stable dynamics.
Determinants of lemming outbreaks
Population outbreaks in tundra rodents have intrigued scientists for a century as a result of their spectacular appearances and their general lessons in ecology. One outstanding question that has led
Fifty thousand years of Arctic vegetation and megafaunal diet
The authors' analyses indicate that both graminoids and forbs would have featured in megafaunal diets, and question the predominance of a Late Quaternary graminoid-dominated Arctic mammoth steppe.
Sources of variation in small rodent trophic niche: new insights from DNA metabarcoding and stable isotope analysis†
This work studies resource use in five arctic small rodent populations of four species combining DNA metabarcoding of stomach contents and stable isotope analysis (SIA) to suggest that for small rodents, the most pronounced effect of competition on trophic niche is due to increased use of secondary habitats and to habitat-specific diets, rather than an expansion of trophics niche in primary habitat.
Habitat selection, reproduction and predation of wintering lemmings in the Arctic
It is concluded that snow cover plays a key role in the spatial structure of wintering lemming populations and potentially in their population dynamics in the Arctic.
Are lemmings prey or predators?
It is suggested that a single mechanism, such as interaction between rodents and predators, is unlikely to provide the ‘universal’ explanation of all cyclic rodent dynamics.
