Blackberries have been enjoyed for their delicious flavor and high nutritional value for hundreds of years. In North America, blackberries were cultivated since 1850-1860. Blackberries have their characteristic and unique aromas depending on the cultivar and growing conditions. The objective of this study was to evaluate the impact of seasonal...
The effect of primocane management on flowering and fruiting patterns was studied in primocane-fruiting blackberry (Rubus subgenus Rubus, Watson) cultivars 'Prime-Jan'® and 'Prime-Jim'® over two years. Primocanes that were "soft-tipped" (upper 2-5 cm removed) at 1.0 m were compared to un-tipped canes. In both years, soft-tipped primocanes developed 2-3 fold...
These data were obtained from GPS radio collared mule deer from 2015-2017 in the John Day Basin. The dataets includes location data for used vs available predictor variable information for time since fire, juniper canopy cover, NDVI, and vegetation community for winter, summer:migratory, summer:resident seasonal ranges. The datasets were used...
In an effort to elucidate the mechanism responsible for large-scale
zooplankton variability in the California Current, zooplankton biomass and
hydrographic data from the California Cooperative Fisheries Investigation
data set and wind data from Fleet Numerical Oceanography Center model
analyses have been used to construct a box model biomass budget. The...
The coastal ecosystem of the Pearl River Estuary (PRE) has been overfished and received a high level of
combined pollution in the past decades. The fisheries stock assessments have shown a declining
population and have led to a number of management measures, including fishing moratorium. This study
evaluated the effect...
This research was conducted in the Mamora cork oak
forest of Morocco to: (1) Describe the impacts of sheep
grazing (none, 35% use, 70% use) in March, April, May and
June of 1987 and 1988 on seasonal forage production; (2)
evaluate the effects of these factors on annual changes
in...
This thesis investigates the behavior of major inorganic nutrients (P, N, Si), trace metals (Mn, Fe), and alkaline-earth metals (Ba) within Tillamook Bay over seasonal cycles and under a range of river discharge conditions from October 1997 through December 1999. Located in the Pacific Northwest region, Tillamook Bay is an...
A study of the fishery problems raised by the construction of the Grand Coulee Dam on the upper Columbia River was done. Part of the study was to estimate the number of salmon taken in commercial fishery for the purpose of comparing this with the number counted as they passed...
Coastal cutthroat trout (Oncorhynchus clarkii clarkii) and cottids (Cottus spp) commonly co-occur in headwater streams in western Oregon. Little is known about the comparative trophic ecology of these species or how they respond to seasonal scarcity of resources. In this study I evaluated the seasonal variability in diets and consumption...
The Calapooia River, a major tributary of the Willamette River in western Oregon, is a watershed typical of many found in the Willamette Basin. Public and private forested lands occur in the steep Upper Zone of the watershed, mixed forest and agriculture lands are found in the Middle Zone, and...
