The current system of managing fish stocks in the North Atlantic is failing: many key stocks are at historically low levels and fishing effort is being restricted while capacity remains high. The traditional scientific approach used by International Council for the Exploration of the Sea (ICES) to provide advice on fish stocks is based on complex analytical models of the fishery that require de...

—Knowledge of the migratory habits of juvenile Pacific salmon Oncorhynchus spp. is required to test the hypothesis that ocean food resources are a limiting factor in their production. Using DNA stock identification techniques, we reconstructed the regional and seasonal changes in the stock composition of juvenile sockeye salmon O . nerka (n 1⁄4 4,062) collected from coastal Washington to the Al...

Implementation of ecosystem-based fisheries management (EBFM) requires a clear conceptual and quantitative framework for assessing how different harvest options can modify benefits to ecosystem and human beneficiaries. We address this social-ecological need for Pacific salmon fisheries, which are economically valuable but intercept much of the annual pulse of nutrient subsidies that salmon prov...

General circulation models predict increases in air temperatures from 1°C to SoC as atmospheric CO2 continues to rise during the next 100 years. Thermal regimes in freshwater ecosystems will change as air temperatures increase regionally. As air temperatures increase, the distribution and intensity of precipitation will change which will in turn alter freshwater hydrology. Low elevation floodpl...

Extension of the rotation length in forest management has been highlighted in Article 3.4 of the Kyoto Protocol to help the countries in their commitments for reduction in greenhouse gas emissions. CO2FIX Model Ver.3.2 was used to examine the dynamics of carbon stocks (C stocks) in a rubber plantation in South Western China with the changing rotation lengths. To estimate the efficiency of incre...

Forests are one of the most important carbon sinks on Earth. However, owing to the complex structure, variable geography, and large area of forests, accurate estimation of forest carbon stocks is still a challenge for both site surveying and remote sensing. For these reasons, the Kyoto Protocol requires the establishment of methodologies for estimating the carbon stocks of forests (Kyoto Protoc...

Two types of honey bees, Apis mellifera L., bred for resistance to Varroa destructor Anderson & Trueman, were evaluated for performance when used for honey production in Montana, and for almond pollination the following winter. Colonies of Russian honey bees and outcrossed honey bees with Varroa-sensitive hygiene (VSH) were compared with control colonies of Italian honey bees. All colonies were...

Previous research suggests that individual investor sentiment has incremental explanatory power for returns of small cap stocks, value stocks, stocks with low institutional ownership, and stocks with lower prices (Kumar and Lee (2003)) and that there is a strong link between institutional sentiment and the returns of large stocks (Brown and Cliff (2004)). With respect to return volatility, Jack...

Manipulation is an important issue for both developed and emerging stock markets. Many efforts have been made to detect manipulation in stock markets. However, it is still an open problem to identify the fraudulent traders, especially when they collude with each other. In this paper, we focus on the problem of identifying the anomalous traders using the transaction data of eight manipulated sto...

Over the past half century fishing has led globally to a reduction in the mean trophic level of commercially landed species, with a significant decline from large predatory fish toward plankton-eating pelagic species and low trophic-level invertebrates [1]. An implied endpoint of this ‘fishing down marine food webs’ is a proliferation of previously suppressed gelatinous plankton (jellyfish) [2]...
