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 ...
Analysing diet of small herbivores : the efficiency of DNA barcoding coupled with high-throughput pyrosequencing for deciphering the composition of complex plant mixtures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009-08-20)
Background: In order to understand the role of herbivores in trophic webs, it is essential to know
what they feed on. Diet analysis is, however, a challenge in many small herbivores with a secretive
life style. In this paper, we compare novel (high-throughput pyrosequencing) DNA barcoding
technology for plant mixture with traditional microhistological method. We analysed stomach
contents of two ...
