Lack of resistance to pink snow mould (Microdochium nivale) is a major constraint for adaptation of perennial ryegrass (Lolium perenne L.) to continental regions with long-lasting snow cover at higher latitudes. Almost all investigations of genetic variation in resistance have been performed using cold acclimated plants. However, there may be variation in resistance mechanisms that are functioning independently of cold acclimation. In this study our aim was to identify candidate genes involved in such resistance...

Data from: Fire history in a western Fennoscandian boreal forest as influenced by human land use and climate

Jørund Rolstad, Ylva-Li Blanck & Ken Olaf Storaunet
Knowing the historical variation in fire regimes is instrumental in managing forests today and in predicting what may happen in the future. By cross-dating 745 fire scars in 378 samples of remnant Scots pines, we delineated 254 individual forest fires during the past 700 years in a 74-km2 section of Trillemarka-Rollagsfjell Nature Reserve in south-central Norway. Fire sizes, numbers, burn rates, and frequencies were compared with historical climate proxies, vegetation maps, and written sources. The...

Data from: A collection of European sweet cherry phenology data for assessing climate change

Bénédicte Wenden, José Antonio Campoy, Julien Lecourt, Gregorio López Ortega, Michael Blanke, Sanja Radičević, Elisabeth Schüller, Andreas Spornberger, Danilo Christen, Hugo Magein, Daniela Giovannini, Carlos Campillo, Svetoslav Malchev, José Miguel Peris, Mekjell Meland, Rolf Stehr, Gérard Charlot & José Quero-García
Professional and scientific networks built around the production of sweet cherry (Prunus avium L.) led to the collection of phenology data for a wide range of cultivars grown in experimental sites characterized by highly contrasted climatic conditions. We present a dataset of flowering and maturity dates, recorded each year for one tree when available, or the average of several trees for each cultivar, over a period of 37 years (1978 - 2015). Such dataset is...

Data from: The extent and meaning of hybridization and introgression between Siberian spruce (Picea obovata) and Norway spruce (Picea abies): cryptic refugia as stepping stones to the west?

Yoshiaki Tsuda, Jun Chen, Michael Stocks, Thomas Källman, Jørn Henrik Sønstebø, Laura Parducci, Vladimir Semerikov, Christoph Sperisen, Dmitry Politov, Tiina Ronkainen, Minna Väliranta, Giovanni Giuseppe Vendramini, Mari Mette Tollefsrud, Martin Lascoux & Giovanni Giuseppe Vendramin
Boreal species were repeatedly exposed to ice ages and went through cycles of contraction and expansion while sister species alternated periods of contact and isolation. The resulting genetic structure is consequently complex, and demographic inferences are intrinsically challenging. The range of Norway spruce (Picea abies) and Siberian spruce (Picea obovata) covers most of northern Eurasia; yet their geographical limits and histories remain poorly understood. To delineate the hybrid zone between the two species and reconstruct...

Data from: What's the meaning of local? Using molecular markers to define seed transfer zones for ecological restoration in Norway

Marte Holten Jørgensen, Abdelhameed Elameen, Nadine Hofman, Sonja Klemsdal, Sandra Malaval & Siri Fjellheim
According to the Norwegian Diversity Act, practitioners of restoration in Norway are instructed to use seed mixtures of local provenance. However, there are no guidelines for how local seed should be selected. In this study, we use genetic variation in a set of alpine species (Agrostis mertensii, Avenella flexuosa, Carex bigelowii, Festuca ovina, Poa alpina and Scorzoneroides autumnalis) to define seed transfer zones to reduce confusion about the definition of ‘local seeds’. The species selected...
