Greater sage-grouse (Centrocercus urophasianus) populations have declined across their geographic range during the last century. They were once widespread throughout the Intermountain West, but lower annual productivity, likely caused by degradation and loss of suitable habitat, has greatly reduced their distribution and population densities. Habitat used for reproduction has been...
The rapid increase in global aquaculture production since the early nineties has increased the demand for fishmeal as an ingredient in aquafeed. This increase has been hypothesized as the source of disruption in the fishmeal market by researchers such as Delgado et al. In this paper we evaluate whether or...
Atlantic Sea scallops have historically supported the second most valuable fishery in the northeastern United States. Intense fishing pressure during the early 1990s led to drastic decreases in population biomass and commercial landings. Total harvest, which exceeded 17,000 metric tons (MT) in 1990, declined to around 7,300 MT in 1993....
By the mid-1990s, Atlantic sea scallop populations in the northeastern United States had been driven to
near depletion due to years of excessive fishing pressure and ineffective fishing regulations. However,
above-average recruitment coupled with new regulations based on reduction of fishing effort and
demarcation of closed areas with restricted access...
This paper discusses the use of options as a tool to retrieve valuable information on the value and level of risk associated with owning a share in a stock of renewable resource. The objective is to show how theory on options trading can be used to obtain information on the...
The Teakettle Ecosystem Experiment in the southern Sierra Nevada is using thinning and prescribed
fire to recreate historical stand conditions. As part of Teakettle we assessed pretreatment diversity and density
of the soil arthropod community in 1998 and 2000. We determined the density and diversity of soil microarthropods
among treatment...
End-user programmers are writing an unprecedented number of programs, primarily using languages and environments that incorporate a number of interactive and visual programming techniques. To help these users debug these programs, we have developed an entirely visual, interactive approach to fault localization. This paper presents the approach. We also present...
