The Autumnal Moth in Fennoscandia
1988Mountain birch, Betula pubescens Ehrhart ssp. tortuosa (Ledebour) Nyman, forests form the tree line in northwestern Europe and are periodically defoliated by the autumnal moth, Epirrita = Oporinia autumnata (Borkhausen). This chapter analyzes the population dynamics of Epirrita, but many of our conclusions may apply to other defoliators, such as ...

Event detectability of seismograph stations in Fennoscandia
Physics of the Earth and Planetary Interiors, 1976Abstract The event detection probability as a function of ISC magnitude shows significant variations between seismic stations in Fennoscandia. In the teleseismic range, the 50% incremental detection thresholds extend from m b = 4.5 to 5.5 among those stations that reported to the ISC during 1964–1969; the best stations being located in Finland ...

Seismic hazard in Fennoscandia: A regionalized study
Tectonophysics, 1993Abstract A seismic hazard evaluation has been conducted for Fennoscandia, including Norway, Sweden, Finland, Denmark, areas of Russia, and adjacent sea areas. Several subregions were considered. Data were taken from a Fennoscandian earthquake catalog comprising both macroseismic and instrumental observations.

Revisiting the Origin of Seismicity in Fennoscandia
Izvestiya, Atmospheric and Oceanic Physics, 2019A review of the literature suggests that the seismic process in Fennoscandia (the Baltic Shield) is affected by at least four mechanisms: (1) northwest-to-southeast movement of the lithospheric plate under the Norwegian and Barents seas by spreading of the Mid-Atlantic Ridge from Iceland to Spitsbergen; (2) postglacial isostatic uplift; (3) local ...

Tectonophysics, 1979
Abstract Seismic risk is calculated by means of recurrence periods, obtained from least squares relations between number of earthquakes and magnitude. This method is described and applied to Fennoscandia. The results, summarized in tabular form, give the seismic risk for 54 regions, each comprising 2° in latitude and 2° in longitude, and for the ...

Seismo-tectonics in Fennoscandia
Geologiska Föreningen i Stockholm Förhandlingar, 1978Abstract Studies of seismic risk in Sweden indicate that there is coherence between the epicentres of earthquakes and the tectonics. On the basis of the existing seismic data and the tectonics, eleven seismo-tectonic zones are suggested for the Fennoscandian Shield.

Diet overlap among ruminants in Fennoscandia
Oecologia, 2000Information on overlap in resource use is central to understanding of interspecific exploitation competition and resource partitioning. Despite this, measures of diet overlap among northern ruminants in Fennoscandia is limited to one earlier study (reindeer and sheep).
