In this paper, the AA. extend the coverage of paleoecologic sites in the Cascade Range by reporting on pollen records from Indian Prairie, in central Oregon. These data disclose the vegetational and climatic history of middle and high elevations

A fully allocated surface water supply in the Upper Deschutes Basin, Oregon, intensifies concern for the watershed's response to climate change. The aim of this paper is to assess the mesoscale hydroclimate in the Upper Deschutes Basin
Downsizing nature : managing risk and knowledge economies through production subcontracting in the Oregon logging sector

The A. tries to explain why the logging sector in Oregon is characterized by extensive subcontracting between wood-commodity manufacturing firms and independent logging contractors. Contracts are a strategy for firms to displace resulting risks

Previous work in the Oregon Coast Range suggested that there may be a tendency locally toward equilibrium between hillslope erosion and sediment yield. Here results from a new methodology based on cosmogenic radionuclide accumulation in bedrock
minerals at the base of the soil column are reported. The AA. quantify how soil production varies with sol thickness in the southern Oregon Coast Range and explore further the issue of landscape equilibrium. Apparent soil production is determined
Die kulturlandschaftliche Bedeutung des primären Wirtschaftssektors im Staate Oregon, USA.. (The influence of the primary economic sector on the cultural landscape in Oregon, USA)
Jusqu'à nos jours, l'Oregon est un état dont l'activité économique principale a été tournée vers le secteur primaire. Son paysage a été modelé par un siècle et demi du peuplement par des colons européens, la population indigène ayant été refoulée
