-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The island-like distribution of subalpine habitats across mountain ranges can trigger the parallel evolution of locally adapted ecotypes. Such naturally replicated scenarios allow testing hypotheses on how elevational ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)Molecular phylogenetics has revolutionized the taxonomy of crustose lichens and revealed an extensive amount of cryptic diversity. Resolving the relationships between genera in the crustose lichen family Tephromelataceae ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)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 ...
