“…The period 9000-5000 B.P. was comparatively warm, and the presently largest glacier in south Norway disappeared completely during this period (Nesje and Kvamme, 1991). No arctic fox material has been recovered from this period; thus the species may actually have been very rare or absent during it.…”

“…(Nesje and Kvamme, 1991), arctic foxes may again have expanded their range. The Little Ice Age period during the 17th and 18th centuries was associated with a great expansion of glaciers in south Norway (Nesje and Kvamme, 1991). The increased temperature since about 1700 (Nesje and Kvamme, 1991) may indirectly have caused the reduction of the arctic fox population during the early part of the 20th century through interaction with an increased population of red foxes.…”

ABSTRACT. We studied the prehistoric and historic distributions of arctic foxes in Norway by examining material and reports from archaeological excavations. A total of 44 arctic fox bones were found in 15 excavations, all of which were younger than 5000 years before present (B.P.). The majority of these sites was located within or close to the present distribution of arctic foxes. Additionally, 44 naturally deposited arctic fox bones were found in two excavations dated 36 000-28 000 and 13 000 B.P. respectively, indicating that the arctic fox also lived along the Norwegian coast in the Pleistocene. No arctic fox bone was dated to the period 9OOO-5000 B.P., and the species may have been rare or absent during this comparatively warm period. Since most bones (61%) were from the distal part of the limbs, the foxes may have been skinned elsewhere and transported to the site of deposition. Bones from red foxes were found in three excavations within the present distribution of arctic foxes, indicating that the arctic fox was relatively more abundant than red foxes during the late prehistoric and the historic periods.in south Norway, but less abundant in north Norway. Key words: arctic fox, red fox, prehistoric and historic distributions, archaeological excavations, Norway RÉSUMÉ.

“…The discrepancy may be due to chronological uncertainties or different developments of the drainage area, which may override the climate signal. During the mid-Holocene there is an increased abundance of pine pollen and macrofossils in lake sediments (Berglund et al, 1996;Barnekow, 1999;Seppä and Weckström, 1999), a high, but decreasing, altitudinal limit for tree megafossils (Karlén, 1976;Kullman, 1995) and evidence for glacier retreat (Karlén, 1976;Nesje and Kvamme, 1991). The oldest pine remains used for dendrochronology in northern Fennoscandia are from c. 7500 cal.…”

spectroscopy at an alpine lake (Sjuodjijaure) in northern SwedenHolocene climatic change reconstructed from diatoms, chironomids, pollen and near-infrared http://hol.sagepub.com/cgi/content/abstract/11/5/551The online version of this article can be found at: Abstract:The results of a multiproxy study reconstructing the climate history of the last 9300 years in northern Sweden are presented. It is based on diatom, chironomid and pollen analyses, as well as near-infrared spectroscopy (NIRS), of a radiocarbon dated sediment core from Sjuodjijaure (67°22ЈN, 18°04ЈE), situated 100 m above tree-line in the Scandes mountains. Mean July air temperature was reconstructed using transfer functions established for the region. The biological proxies show significant changes in composition during the Holocene and the inferred temperatures all follow the same general trend. For the period between about 9300 to 7300 cal. BP the reconstructions should be interpreted with caution due to the lack of convincing modern analogues in the training set. However the reconstruction suggest that July temperature was on average about the same as today, with several rapid short-term cold and warm periods. Cold periods were dated to about 8500, 8200 and 7600 cal. years BP and a warm period to about 7700 cal. BP. About 7300 cal. BP, a major shift to a warmer climate occurred. Pine migrated into the area, which was previously covered with birch forest. From the mid-Holocene until today the sediment record suggests a descending tree-limit and a gradual lowering of July temperature.

A stratigraphic succession of alternating peat and minerogenic sediments at the foot of a steep mountain slope provides the basis for the reconstruction of a preliminary colluvial history from the alpine zone of Jotunheimen, southern Norway. Layers of silty sand and sandy silt, typically 5–10 cm thick and interpreted as distal debris‐flow facies, are separated by layers of peat that have been radiocarbon dated. Deposition from at least 7500 to about 3800 14C yr BP of predominantly minerogenic material suggests relatively infrequent but large‐magnitude debris‐flow events in an environment warmer and/or drier than today. Particularly low colluvial activity between about 6500 and 3900 14C yr BP was terminated by a succession of major debris‐flow events between about 3800 and 3400 14C yr BP. Unhumified peats indicative of higher water tables, separate six debris‐flows that occurred between about 3300 and 2300 14C yr BP and signify a continuing high frequency of colluvial activity. Uninterrupted peat accumulation between about 2400 and 1600 14C yr BP indicates reduced debris‐flow activity; subsequent renewed activity appears to have culuminated in the ‘Little Ice Age’ after about 600 14C yr BP. This pattern of colluvial deposition demonstrates a long history of natural Holocene low‐alpine landscape instability, suggests an increase first in the magnitude and then in the frequency of debris‐flow activity coincident with late Holocene climatic deterioration, and points to the potential of debris‐flow records as a unique source of palaeoclimatic information related to extreme rainfall events. © 1997 John Wiley & Sons, Ltd.
