TL;DR: The identification of distinct 14C excursions in 484 individual tree rings enable the authors to confirm the dating of 44 dendrochronologies from five continents, and suggest a global exposure to strong solar proton radiation.
Journal ArticleDOI
Growth of mature boreal Norway spruce was not affected by elevated [CO 2 ] and/or air temperature unless nutrient availability was improved
TL;DR: It is concluded that the low nutrient availability (mainly nitrogen) in the boreal forests is likely to restrict their response to the continuous rise in [CO(2)] and/or TE.
Journal ArticleDOI
Influence of annual weather on growth of pedunculate oak in southern Sweden
TL;DR: In this paper, a network of oak (Quercus robur L.) chronologies containing 49 sites and 635 single trees was analyzed to identify weather variables affecting annual tree-ring increment dynamics in southern Sweden during 1860-2000.

Journal ArticleDOI
Tracing the origin of Arctic driftwood
Lena Hellmann,Willy Tegel,Ólafur Eggertsson,Fritz H. Schweingruber,Robert A. Blanchette,Alexander V. Kirdyanov,Holger Gärtner,Ulf Büntgen +7 more
TL;DR: In this article, driftwood remains from coastal East Greenland and Svalbard were used for wood anatomical classification, a multi-species subset was used for detecting fungi; and information on boreal vegetation patterns, circumpolar river systems, and ocean current dynamics was reviewed and evaluated.
