The Southeast Alaska Coastal Monitoring (SECM) project has been sampling juvenile salmon (Oncorhynchus spp.) and associated environmental parameters in northern Southeast Alaska (SEAK) since 1997 to better understand effects of environmental change on salmon production. A pragmatic application of this effort is to forecast the abundance of adult salmon returns in subsequent years. Since 2004, j...

The impacts of three different water stresstiming patterns for three levels of seasonal applied water on production were evaluated in mature almond trees [Prunus dulcis (Mill.) Webb cv. Nonpareil] grown under high-evaporative demand conditions in the southern San Joaquin Valley of California. The stress timing patterns involved biasing water deficits to the pre-harvest or postharvest periods in...

The appropriate planting pattern of safflower in summer planting might be different from the planting pattern suitable for spring planting, and this has not been determined under Isfahan environmental conditions. A field experiment was conducted in the summer of 2000 at the Agricultural Research Station, Isfahan University of Technology, using a randomized complete block design with a split plo...

A GIS model predicting the spatial distribution of terrestrial salamander abundance based on topography and forest age was developed using parameters derived from the literature. The model was tested by sampling salamander abundance across the full range of site conditions used in the model. A regression of the predictions of our GIS model against these sample data showed that the model has a m...

The objective of this study was to evaluate the effect preharvest application 1-methylcyclopropene (1-MCP) on postharvest dissipation stress watercore incidence and severity rating over 30 d at 20 °C. ‘Jonagold’ trees were untreated or sprayed with 1-MCP one week before harvest. Harvest indices quality factors °C, assessed days 2, 5, 9,15, 20, 30. Fruit treated treatment had lower internal ethy...

1 Fresh data on English grain yields 1268-1480 are combined with revised price series to measure the frequency and scale of serious harvest shortfalls and estimate the elasticity of demand for cereals. Major food availability declines are shown to have been a significant component of most historical subsistence crises, as back-to-back shortfalls were of the worst famines. Although farmers did a...

Life history traits of wild animals can be strongly influenced, both phenotypically and evolutionarily, by hunting and fishing. However, few studies have quantified fishery selection over long time periods. We used 57 years of catch and escapement data to document the magnitude of and trends in gillnet selection on age and size at maturity of a commercially and biologically important sockeye sa...

The Table Interpolation Program for Stand Yields (tipsy) enables forest managers and timber supply analysts to explore the impacts of variable retention. tipsy variable retention adjustment factors (vrafs) are calculated based on the level and pattern of both group and dispersed tree retention using four primary variables from the retained stand: percent crown cover, average group or crown size...
