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 founder effect on five islands is associated with dispersal distance, island size and species traits. Most species colonized postglacially via multiple dispersal events from several ...
Genetic roadmap of the Arctic: plant dispersal highways, traffic barriers and capitals of diversity
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013-07-22)
<ul> <p><li>We provide the first comparative multispecies analysis of spatial genetic structure and diversity in the circumpolar Arctic using a common strategy for sampling and genetic analyses. We aimed to identify and explain potential general patterns of genetic discontinuity/connectivity and diversity, and to compare our findings with previously published hypotheses.</li></p> <p> <li>We ...
Frequency of local, regional, and long-distance dispersal of diploid and tetraploid Saxifraga oppositifolia (Saxifragaceae) to Arctic glacier forelands
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
Climate change forces many species to migrate. Empirical small-scale data on migration and colonization in the Arctic are scarce. Retreating glaciers provide new territory for cold-adapted plant species, but the genetic consequences depend on dispersal distances and frequencies. We estimated local, regional, and long-distance dispersal frequencies, as well as their effect on levels of genetic ...
