Trans-Atlantic genetic uniformity in the rare snowbed sedge Carex rufina
(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
The red-listed, amphi-Atlantic sedge Carex rufina is highly specialized to certain alpine snowbeds, and threatened by current changes in snow cover duration and moisture conditions. Here we address its range-wide genetic ...
Past Arctic aliens have passed away, current ones may stay
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-07-04)
Increased human activity and climate change are expected to increase the numbers and impact of alien species in the Arctic, but knowledge of alien species is poor in most Arctic regions. Through field investigations over ...
Range shifts and global warming: ecological responses of Empetrum nigrum L. to experimental warming at its northern (high Arctic) and southern (Atlantic) geographical range margin
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
Global change is expected to lead to range shifts of plant species. The ecological mechanisms underpinning these shifts are currently not well understood. Here, we compared ecological responses possibly underlying southern ...
Long-distance plant dispersal to North Atlantic islands: colonization routes and founder effect
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-15)
Long-distance dispersal (LDD) processes influence the founder effect on islands.We use genetic data for 25 Atlantic species and similarities among regional floras to analyse colonization, and test whether the genetic ...
Characterization of 14 microsatellite markers for Silene acaulis (Caryophyllaceae)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-08)
Premise of the study: Fifty candidate microsatellite markers, generated using 454 shotgun sequencing, were tested for the widespread arctic/alpine herb Silene acaulis (Caryophyllaceae). Methods and Results: Fourteen out ...
Reconstructing the invasion history of Heracleum persicum (Apiaceae) into Europe
(Journal article; Tidsskriftartikkel, 2015-11-06)
Sparse, incomplete and inappropriate historical records of invasive species often hamper invasive species management interventions. Population genetic analyses of invaders might provide a suitable context for the identification ...
Biological introduction risks from shipping in a warming Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-14)
Several decades of research on invasive marine species have yielded a broad understanding of the nature of species invasion mechanisms and associated threats globally. However, this is not true of the Arctic, a region where ...
Microsatellite markers for Heracleum persicum (Apiaceae) and allied taxa: application of next-generation sequencing to develop genetic resources for invasive species management
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
Plant DNA in sediments: to which degree do they represent the flora?
(Conference object; Konferansebidrag, 2015-05)
Climate change, non-indigenous species and shipping: assessing the risk of species introduction to a high-Arctic archipelago
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
Aim: Anticipated changes in the global ocean climate will affect the vulnerability of marine ecosystems to the negative effects of non-indigenous species (NIS). In the Arctic, there is a need to better characterize present ...
