The introduction of fish to the Scandinavian mountains by hunter-fisher-gatherers 5000 BC
Deglaciation of the Fennoscandian Ice Sheet ( c . 8000 BC) opened the mountainous areas of inland southern Norway for human habitation, but topographic barriers prevented the migration of fish into upland watercourses. Dates from four fish traps found in the exposed bed of Lake Tesse, within the central mountainous region of Norway, are reported here, with the earliest (at around 5000 BC) indicating that Mesolithic hunter-fisher-gatherers were ex…
Ecuadendro 2025
The 1st Ecuadorian Dendrochronology Conference (ECUADENDRO 2025) took place in Daule, Ecuador, on January 23–24, 2025, with the generous sponsorship of the Tree-Ring Society. The event attracted 230 participants from 45 countries, bringing together leading experts in various subfields of tree-ring science, including dendroclimatology, dendroecology, dendrogeomorphology, dendroarchaeology, and cellular dendrochronology. Fifteen international speak…

Little Ice Age summer temperatures in western Norway from a 700-year tree-ring chronology
A ring-width Pinus sylvestris chronology from Sogndal in western Norway was created, covering the period AD 1240–2008 and allowing for reconstruction of monthly mean July temperatures. This reconstruction is the first of its kind from western Norway and it aims to densify the existing network of temperature-sensitive tree-ring proxy series to better understand past temperature variability in the ‘Little Ice Age’ and diminish the spatial uncertain…
A 1200-year multiproxy record of tree growth and summer temperature at the northern pine forest limit of Europe
Combining nine tree growth proxies from four sites, from the west coast of Norway to the Kola Peninsula of NW Russia, provides a well replicated (> 100 annual measurements per year) mean index of tree growth over the last 1200 years that represents the growth of much of the northern pine timberline forests of northern Fennoscandia. The simple mean of the nine series, z-scored over their common period, correlates strongly with mean June to August …
A 500-year record of summer near-ground solar radiation from tree-ring stable carbon isotopes
Tree-ring stable carbon isotope ratios (d 13 C) in environments of low moisture stress are likely to be controlled primarily by photosynthetic rate. Therefore, sunshine, rather than temperature, represents the more direct controlling factor. Temperature reconstructions based on tree-ring d 13 C results thus rest on the assumption that temperature and sunshine are strongly coupled. This assumption is tested using a d 13 C series from pine trees in…
Reconstruction of summer temperatures from tree-rings of Scots pine (Pinus sylvestris L.) in coastal northern Norway
At the coast of northern Norway, 69°N, tree-ring chronologies from Scots pine (Pinus sylvestris L.) were constructed at Forfjorddalen in the Vesterålen archipelago (AD 1358-1992), Stonglandseidet on Senja (AD 1548-1994) and Vikran near Tromsø (AD 1700-1992). All chronologies reflect July-August temperatures. At the most northern site, Vikran, the response was more confined to July temperatures, resulting in a strong tree-ring and climate signal. …
