Temperate forest species, including Fagus crenata Blume, have been experiencing distributional shifts during the climate oscillation throughout Holocene epoch. This review describes distinctive context of F. populations at northern range from perspective past distribution shifts, future expansion predictions, biotic and abiotic interactions in population establishment, vegetation characteristic...

On the mid-Norwegian margin, extensive rifting and subsequent deposition of thick Cretaceous Cenozoic sediments have buried traditional Upper Jurassic organic-rich shales too deep. Consequently, these are overmature spent in deep basins on margin. The absence well-control, variable seismic quality particularly, great burial depth, makes it difficult to identify alternative Lower units. By combi...

The Cainozoic history of the Malanna area included faulting, deposition of sediments by streams or in lakes and swamps, two epochs of planation, and stream erosion. There is no physiographic, depositional or structural evidence for gladation in this area, the type area of Lewis's Malanna Phase of the Pleistocene glaciation. This phase must be considered invalid on the eviaence available in the ...

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

The spatial variabi]Lity and co-variability of two different types of remote sensing derivatives that portray vegetation and geomorphic patterns are analyzed in the context of estimating regional-scale CO 2 flux from land surfaces in the arctic tundra. For a study area encompassing the Kuparuk River watershed of the North Slope of Alaska, we compare satellite-derived maps of the normalized diff...

Acquisition of nearly complete coverage of Thematic Mapper data for the central Andes between about 15’s to 34’s has stimulated a comprehensive and unprecedented study of the interaction of tectonics and climate in a young and actively developing major continental mountain belt. The paper briefly reviews the current state of our synoptic mapping of key physiographic, tectonic and climatic indic...

In this chapter, we review the historical arc of research on biogeomorphic interactions between fluvial geomorphology and riparian vegetation. We then report on an examination of the past 20 years of published research on this topic. Having classified studies according to the key relationships they have identified, we map those relationships to seek spatial patterns that emerge in terms of eith...

Information based agriculture (IBA) includes matching of agronomic practices with soil and water characteristics and their spatial variability for enhancing productivity. An attempt was made to derive agriculture management zones based on soil and water characteristics for sustainable agricultural production in Mansa district (Punjab, India). Based on physiographic analysis and semi detailed so...
