Highly overlapping winter diet in two sympatric lemming species revealed by DNA metabarcoding
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-01-30)
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 thus reduced diet
overlap is expected. We present here the first assessment of diet overlap of high arctic lemmings
during winter based on DNA ...

Not only mosses: lemming winter diets as described by DNA metabarcoding
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-01)
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 ...
