Grain is produced on upwards of 100,000 acres in the Klamath Basin including nearly 50,000 acres within the Klamath Reclamation Project. Susceptibility to late spring frosts has historically limited winter cereal production and spring cereals have accounted for the majority of production. Klamath Basin Research & Extension Center (KBREC) cereal...
Concerns were raised about loss of soil from wind erosion with the announcement in early 2010 that most Klamath Reclamation Project water users would receive a delayed and reduced rate of irrigation water during the 2010 growing season, with some areas potentially receiving no irrigation water for the entire season....
Euphorbia lagascae (Euphorbiaceae- ‘spurge family’) has been recognized as one of the more promising potential new industrial crops for the drier regions in the temperate zone
(Roseberg, 1996). In the late 1950s and early 1960s the USDA analyzed many plant species in search of novel chemical compounds. They first recognized...
Non-market valuation research has produced value estimates for over forty threatened and endangered (T&E) species, including mammals, fish, birds, and crustaceans. Increasingly Stated Preference Choice Experiments (SPCE) are utilized for valuation, as the format offers flexibility for policy analysis and may reduce certain types of response biases as compared to...
Incorporating catch or harvest rate information in repeated-choice recreation fishing demand models is challenging, since multiple sources of information may be available and detail on how harvest rates change within a season is often lacking. This paper develops a framework for evaluating which source(s) of information should be used to...
Results from vegetation management trials involving horticultural crops conducted during the past year are compiled and reported by faculty members of the Oregon Agricultural Experiment Station, the Oregon State Extension Service, and colleagues who cooperated from adjacent states along with local enterprises. This work was conducted throughout Oregon and involved...
This is an evaluation report for the installation of the Magic Planet exhibit at the Hatfield Marine Science Center. The report is on file with NOAA and is Oregon Sea Grant Publication ORESU-S 10-04.
This white paper gives an overview of the software applications used by university presses to publish digital monographs. In addition, we will look at routes taken by university presses to move from all print to some e-publishing and list the supplemental online content that is typically offered for a fee.
We introduce a model for the surplus of nonprofit organizations (NPO). We assume two types of spending schemes for an NPO. Type I is a constant spending rate and Type II is a variable rate above and below a cut-off reserve level. Under steady state, we compute and compare the...
Epidermal RNA samples from FVB/N mice treated with PAH standards and
environmental PAH mixtures were harvested and purified using Trizol extraction and
RNeasy mini prep kit purification. Epidermal RNA integrity was low (RIN mean 3.5),
indicating significant RNA degradation and the need to modify handling, collection, and
processing of skin...
It has been claimed that stimuli signaling threat are processed rapidly and
draw our attention (e.g., Fox, Russo, & Dutton, 2002). Similarly, it has been
argued that expressions of fear have a strong pull on our attention because
they signal threat (e.g., Phelps, Ling, & Carrasco, 2006; Vuilleumier &
Schwartz,...
We study the stability properties of, and the phase error present in, several higher order (in space) staggered finite difference schemes for Maxwell's equations coupled with a Debye or Lorentz polarization model. We present a novel expansion of the symbol of finite difference approximations, of arbitrary (even) order, of the...
In an effort to foster a collaborative approach to advancing the ocean energy industry, OWET convened the OWET 2010 Developersʼ Summit on September 27 and 28, 2010 in Portland, Oregon. The purpose of the Summit was to create an open dialogue among developers, utilities, and regulatory and policy leaders to...
Changes in ownership of limited entry permits by “local” residents of the region where a fishery occurs
may have significant economic and social implications for fishery-dependent regions. This paper
examines changes in local permit ownership in Alaska salmon fisheries, for which a long-term decline in
rural local permit ownership is...
One component of the Bering Sea Integrated Ecosystem Research Project
(BSIERP) is a spatial economic model that predicts changes in fishing
activity in the Bering Sea pollock fishery that may result from climate
change. Models such as the one employed here have been used in the
Bering Sea and elsewhere...
Based on the evoked set analysis, a group of factors driving knowledge and preferences about fish farmed species are investigated with three different samples. Samples were collected in Spain, into a nationwide study about knowledge and assessments about aquaculture, funded by the General Secretary of Marine Fisheries of the Spanish...
This paper discusses the use of resource assessment surveys as the basis for effective fisheries management drawing on the resource assessment survey of the Arabian Sea coast of Oman. This survey, completed in 2009, has been undertaken in the context of the primary aim of the Oman Ministry of Fisheries...
Vietnam is the peninsular country and lying in the area of monsoon tropical climate therefore has very diversify and abundant and valuable fish resources. Since long time ago the fisheries resources in natural water bodies (as in dams, rivers, lake, canals, sea) have been concerned as common property (and is...
This paper investigates interactions between recreational and commercial fisheries. It introduces the idea of a protected area for recreational fisheries, as a way to reduce conflicts between the two sectors and to preserve the natural resource. It is demonstrated that without a protected area for recreational fisheries, open access may...
The coastal fishery in French Guyana is a challenging case study for the implementation of the ecosystem based fishery management. Although the current situation of this small scale fishery could be considered as satisfactory, the viability of the fishery can be questioned. Indeed according to demographic scenarios, the growth of...
Species within marine ecosystems are known to be interconnected. This is
a result of many factors including predation and competition for resources.
Despite this, many fisheries are still managed using a single species
framework. This paper uses cointegration analysis to quantify the
relationship between different fish species. Cointegration is a...
Tuna fisheries around the world are governed by Regional Fishery Management Organizations (RFMOs), whose membership includes both harvesting nations and nations in whose waters the targeted fish populations reside. The outcomes of the policies established by an RFMO will depend on subsequent interactions among the fleets, the fishing sites and...
Economists have long promoted fishery rationalization programs, but ITQs may fail to address the
ecological consequences of fishing. Of particular concern is that economic incentives to harvest larger
fish (due to size-dependent pricing or quota-induced discarding) can destabilize fish populations or lead to
evolutionary changes. A substantial theoretical literature in...
The credit crunch has had a dramatic effect within the seafood industry. Recent years saw a buoyant UK economy with increasing sales of chilled seafood material and a growing interest in sustainability. Credit tightening and declining consumer confidence has placed pressures on these trends. This is unlikely to be reversed...
This study estimates the demand for saltwater recreational angling trips
within the Southern California Commercial Passenger Fishing Vessel
(CPFV) fishery. The CPFV fishery provides a variety of trip types to
support recreational anglers targeting several species including, tuna,
rockfish, yellowtail, and shark. Trips vary by fishing location, by length of...
Many of the coastal counties in Florida have active artificial reef
deployment and monitoring programs. These reef systems have been
shown to be an important destination for the marine recreational boating
industry, as well as for the for-hire commercial sector (i.e., six-pack charter
vessels, guide boats, party/head boats, and dive...
The motivation of this paper is to detail the application of Markov chains in
simulating fleet dynamics in Australia's Northern Prawn Fishery (NPF).
The Markov chains are enhanced through the use of the multinomial logit
(MNL) and Seemingly Unrelated Regressions (SUR) models to explain
transition probabilities. The terms MNL Markov...
The past twenty years has seen the offshore outsourcing of post-harvest
fish processing gain unprecedented momentum. The growth in offshore
processing is a further stage in an increasingly globalised fisheries value
chain. Raw material is head and gutted, then frozen, and transported to
processing sites in Asia (especially China). The...
The spatial, multi-species nature of coral reef fisheries makes them notoriously difficult to manage. We
have developed a simulation modeling approach to examine the effect of management options on the
recreationally important tourist destination of Ningaloo Reef in Western Australia where a recreational
fishery targets Spangled Emperor (Lethrinus nebulosus). The...
This paper is based on a review and assessment of lessons from three
projects on fisheries co-management in Bangladesh: i) Community-based
fisheries management (CBFM), ii) Management of aquatic ecosystems
through community husbandry (MACH), and iii) Fourth Fisheries Project
(FFP). These co-management initiatives established 191 Community Based
Organizations (CBOs) in 179...
