The dynamic Quaternary geology of the Pacific Ring of Fire created substantial challenges for biogeography. Fish life history and population genetic variation were shaped by climate change, repeated formation and subsidence of ice sheets, sea-level change, volcanism and tectonics, isostatic rebound, and now human activities. It is widely recognized in...
A continuing challenge for commercializing 1-methylcyclopropene (1-MCP) to extend the storage life and control superficial scald of ‘d’Anjou’ pear (Pyrus communis L.) is how to initiate ripening in 1-MCP treated fruit. ‘D’Anjou’ pears harvested at commercial and late maturity were treated with 1-MCP at 0.15 μL L⁻¹ and stored either...
‘Anjou’ and ‘Comice’ pears from three harvest dates were conditioned to develop ripening capacity by exposure to 100 μL L⁻¹ ethylene at 20 °C for 0, 24, 48, or 72 h, followed by varying durations of temperature conditioning at -0.5 or 10 °C. Ripening capacity was tested by measuring fruit...

Blankenship, S.M., Richardson, D.G., 1985. Development of ethylene biosynthesis and
Alcoholic off-flavor and accompanying volatile compounds produced by bananas (Cavendishii spp) held at 20°C and subjected to aerobic (air control treatment) or anaerobic conditions (nitrogen treatment) were compared by solid phase micro extraction (SPME), a newly developed method for volatile separation. In general, volatile production was suppressed under anaerobic conditions...
A fruit color descriptive study was conducted on 'Max' and 'Sensation' Red Bartlett, 'Columbia' and 'Gebhard' Red Anjou, 'Rogue Red', 'Rosired', 'Red Clapp' and 'Cascade' red pear varieties. A parallel comparative study was done to test differences between related red strains. 'Max' was compared with 'Sensation' in three different growing...
Chinook salmon are widely distributed across the globe with native stocks in the North Pacific Ocean and self-sustained populations introduced to regions in the Northern and Southern Hemispheres. Pacific salmon are economically and ecologically important to the Pacific Northwest, USA, yet several wild populations are federally listed as endangered or...
In apples, the rapid changes occurring in fruit metabolism when approaching maturity affect their quality at harvest and after storage. The interest in the newly introduced cultivars, 'Gala', 'Braeburn' and 'Fuji' has initiated the following study on maturity indices and storage in the conditions of the Pacific Northwest. 'Gala', 'Braeburn'...
The application of DNA-based markers toward the task of discriminating among alternate
salmon runs has evolved in accordance with ongoing genomic developments and
increasingly has enabled resolution of which genetic markers associate with important
life-history differences. Accurate and efficient identification of the most likely origin for
salmon encountered during ocean...
