The fillet yield phenotype is a trait that can be improved in aquaculture species through conventional selective breeding. This approach was applied to rainbow trout for three consecutive generations of selection to produce a high-yield line (HY) that exhibits 2.5 percentage points higher fillet yield compared to a low-yield line (LY). To characterize the genetic and physiological mechanisms contributing to the HY phenotype, t...

Chronic infection with hepatitis C virus (HCV) results in an increased risk of cirrhosis and hepatocellular carcinoma (HCC). Only 15% of baby boomers (born 1945–1965) have ever been screened. We aimed to develop a multilevel intervention to increase HCV screening for baby boomers in a primary care setting. This study included two phases: intervention development ( phase 1 ) and feasibility testing ( phase 2 ). In phase 1, we p...

The simultaneous quantification of several transcripts via multiplex PCR can accelerate research in fish physiological responses to diet and enable the development of superior aquafeeds for farmed fish. We designed two multiplex PCR panels that included assays for 40 biomarker genes representing key aspects of fish physiology (growth, metabolism, oxidative stress, and inflammation) and 3 normalizer genes. We used both panels t...

Tropical forests play a dominant role in the global carbon (C) cycle, and models predict increases in tropical net primary productivity ( NPP ) and C storage in response to rising atmospheric carbon dioxide ( CO 2 ) concentrations. The extent to which increasing CO 2 will enhance NPP depends in part on the availability of nitrogen (N) and phosphorus (P) to support growth. Some tropical trees can potentially overcome nutrient l...

High rates of land conversion and land use change have vastly increased the proportion of secondary forest in the lowland tropics relative to mature forest. As secondary forests recover following abandonment, nitrogen (N) and phosphorus (P) must be present in sufficient quantities to sustain high rates of net primary production and to replenish the nutrients lost during land use prior to secondary forest establishment. Biogeoc...

Ecology Letters (2011) 14 : 939–947 Abstract Tropical rain forests play a dominant role in global biosphere‐atmosphere CO 2 exchange. Although climate and nutrient availability regulate net primary production (NPP) and decomposition in all terrestrial ecosystems, the nature and extent of such controls in tropical forests remain poorly resolved. We conducted a meta‐analysis of carbon‐nutrient‐climate relationships in 113 sites...
