Using subnivean camera traps to study Arctic small mammal community dynamics during winter
Arctic Science, 2022 Small rodents are a key indicator to understand the effect of rapidly changing winter climate on Arctic tundra ecosystems. However, monitoring rodent populations through the long Arctic winter by means of conventional traps has, until now, been hampered ...

Arctic Science, 2020 Morphological differentiation and relationships among collared lemmings (Dicrostonyx Gloger, 1841) remain unclear. This issue is particularly important in the Kivalliq Region, Nunavut, Canada, where Dicrostonyx groenlandicus (Traill, 1823) and ...

Determinants of lemming outbreaks [PDF]
Proceedings of the National Academy of Sciences, 2011 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 to competing hypotheses is why sympatric lemmings and voles differ in regularity and shape of their outbreaks.

Fire and Snow: Effects of Snowpack Variation and Wildfire on Small Mammal Dynamics in Sub-Alpine Habitats. [PDF]
Ecol EvolGlobal warming is increasing the risk of fire and decreasing winter snow cover in montane environments in many parts of the world. Using a long term trapping study in sub‐alpine habitats in the Australian Alps, we show that changes in the fire regime and snow conditions interact with other factors (availability of food and predation by introduced ...

Optical design challenges of subnivean camera trapping under extreme Arctic conditions
Arctic Science, 2022 Camera trapping is widely used in different ecological studies and is particularly important for remote locations and extreme environments. However, the application of camera traps in Arctic regions remains very limited.

Lemmings : le récit de science-fiction et le « vice de forme »
ReS Futurae, 2020 The article compares two short stories by two writers who are very different and relatively distant from one another in space and time. For both, the same animal metaphor (the legendary suicidal race of lemmings) expresses an essential concern : the ...

Lemmings Is PSPACE-Complete [PDF]
Theoretical Computer Science, 2014 Lemmings is a computer puzzle game developed by DMA Design and published by Psygnosis in 1991, in which the player has to guide a tribe of lemming creatures to safety through a hazardous landscape, by assigning them specific skills that modify their behavior in different ways. In this paper we study the optimization problem of saving the highest number

Highly overlapping winter diet in two sympatric lemming species revealed by DNA metabarcoding. [PDF]
PLoS ONE, 2015 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 example of a situation where food availability is anticipated to be low, and ...

Phylogeography and ecology of bumble bees on Kolguev Island, a remote European Arctic landmass [PDF]
ZooKeys, 2022 The bumble bee fauna of the Russian Arctic is rather poorly known. Kolguev Island, a remote insular territory in the Barents Sea, is one of the deficiently studied areas.
