Transferability of biotic interactions: temporal consistency of arctic plant-rodent relationships is poor
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-17)
Variability in biotic interaction strength is an integral part of food web functioning.
However, the consequences of the spatial and temporal variability of biotic interactions
are poorly known, in particular for predicting species abundance and distribution.
The amplitude of rodent population cycles (i.e., peak-phase abundances) has
been hypothesized to be determined by vegetation properties ...
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 ...
