It is well known that world production of shrimp, particularly farm-raised product, has increased significantly since the early-to-mid 1980's and that much of the product is directed to the U.S. market. Less well known is the fact that the product composition of the U.S. imported product (e.g., headless shell-on, peeled)...
Medusahead (Taeniatherum asperum Nevski), a winter annual native to the Mediterranean region of Eurasia, has infested several million acres of rangeland in the northwestern United States. It has been estimated carrying capacity for domestic livestock on infested ranges has been reduced 75 percent.
The review is a condensed summarization of...
This article investigates the origins of the variability of the Malvinas Current (MC)
transport using the results of an eddy-permitting ocean general circulation model. First, the
dynamical links between the variabilities of the MC and the Antarctic Circumpolar
Current (ACC) transports at the Drake Passage are established. Time series analyses...
In recent years, considerable attention has been given to the effects of removing trade restrictions on natural resource utilization and on poverty, especially in developing countries. Our paper adds to the growing body of conceptual work to show conditions under which a developing country that, in isolation, is unable to...
Theory suggests that fishing effort would be allocated among various fishing grounds such that profit levels would be equal. Homogeneity among fishers as well as perfect information is assumed and profits are opportunistically increased by changing fishing locations. These assumptions have been shown empirically ins some single fisheries where fishers...
In response to growing concerns about illness and deaths associated with Vibrio Vulnificus, California initiated a program in March 1991 that required anyone selling oysters to notify potential consumers that the “consumption of raw oysters can cause serious illness and death among people with liver disease, chronic illness, or weakened...
The shrimp fishery accounts for more than one-half of the total revenues generated by commercial fishing activities in the U.S. Gulf of Mexico. Due to its historical open access nature the harvesting sector has historically been overcapitalized (from an economic perspective) resulting in a suboptimal generation of rents. Various management...
We compared the potential fire behavior and smoke production of historical and current time periods based on vegetative conditions in forty-nine 5100- to 13 500-hectare watersheds in six river basins in eastern Oregon and Washington. Vegetation composition, structure, and patterns were attributed and mapped from aerial photographs taken from 1932...
