During October 2000 the Po River, Italy's largest river, experienced a historically significant flood, producing a deposit on the adjacent prodelta. In December 2000 an event-response study of the deposit was conducted, and during the ensuing 16 months three additional sampling cruises were conducted to study the subsequent evolution of...
During two cruises in February and June of 2003, the erodibility of sediment along the western Adriatic Sea was measured using a "Gust erosion chamber". In addition, the surficial sediment properties were characterized through a suite physical and biological measurements including porosity, grain-size, inorganic carbon, organic carbon and colloidal carbohydrate....
Seasonal emergent wetlands in the Pacific Northwest have not been regarded traditionally as fish rearing habitat, despite access to such habitat when river flows overtop riverbanks and connect to the floodplain. As a result, restoration and enhancement projects to remediate for the loss of such wetland habitat are being implemented...
Redband trout (Oncorhynchus mykiss gairdneri) are found over a wide range of environmental conditions and are known for their variability in life history traits among watersheds or even within streams. Life history traits and population structure of these trout can be influenced by a variety of anthropogenic changes including habitat...
Because human land use activities often result in increased fragmentation of headwater stream habitats, a better understanding of the effects of fragmentation on the genetic heterogeneity of stream salmonids is useful for effective management. We used eight microsatellites to examine the genetic structure of potamodromous coastal cutthroat trout (Oncorhynchus clarki...
Beach response to overwash processes is a topic of significant importance. Two
particular aspects of this topic were chosen for detailed analysis: the distribution of
maximum wave runup elevations and the cross-beach celerity gradient of overwash bores
on natural beaches. Data were collected using both traditional nearshore instrumentation
and recently...
The Eyjafjöll Volcanic System, in southern Iceland, is a member of the
Southeastern Volcanic Zone (SEVZ), a segment of the Mid-Atlantic Ridge. The
SEVZ is a well-exposed (subaerial) propagating rift, analogous to the
volcano-tectonic structures that accommodate the growth of ocean floor
spreading ridge segments. Eyjafjöll represents 780 Ka of...
This is a study of the representations of prostitutes and prostitution produced within a particular historical framework-regulationism. Drawing support from public health movements, campaigns against depopulation and degeneration and protest from feminists and socialists, the "French system" of regulation of prostitution occupied center stage in social debates from the mid-nineteenth...
We investigate, theoretically and experimentally, the problem of modeling depth-integrated (2DH) surf zone circulation on an alongshore-nonuniform natural beach, with waves approaching from an arbitrary angle. An approximate theoretical model is developed, which captures the important effect of advection in the alongshore dynamics, and shows that a nondimensional parameter Re[subscript]s...
Craterellus tubaeformis is a small to medium-sized forest mushroom that is fairly common in the Douglas-fir/western hemlock forests of the Pacific Northwestern United States and is most often associated with decayed coarse woody debris. In this study, the mycorrhizae of Craterellus tubaeformis in western Oregon is identified by DNA analysis...
