European hazelnut (Corylus avellana L.) is a diploid with 11 pairs of chromosomes (2n = 2x = 22), monoecious, dichogamous and wind-pollinated. Eastern filbert blight (EFB) caused by Anisogramma anomala is a serious disease of European hazelnut (Corylus avellana) in North America, and infection leads to cankers that girdle branches...
The Applegate Fire Plan is a collaborative effort, hatched from an idea that was developed jointly by local citizens and federal agency folks in the Spring of 2001. Due to wide-spread participation throughout the Applegate Valley, general project coordination was organized by the Applegate Partnership, a non-profit communitybased group founded...
The Upper Ojai Valley is a tectonic depression between
opposing reverse faults, Its northern border is formed
by the active, north-dipping San Cayetano fault with 6.0
km of dip-slip displacement in the Silverthread oil field
and 2.6 km displacement west of Sisar Creek; the fault
dies out farther west in...

The spatial distribution and geologic histories of submarine volcanoes provide insight into submarine eruptive behavior, deep earth processes and plate tectonics. This dissertation examines the evolution of individual submarine volcanic edifices as well as linear trails of seamounts at three spatial and temporal scales.
In order to understand constructive and...
Host-parasite interactions between the pathogen, Sphaerulina musiva, and its host, Populus spp., were examined in a series of studies. In the first study, variation in resistance of Populus nigra from 7 locations in Europe was differentiated based on the parameters cankers per cm and disease severity score. The analysis evaluated...
This publication outlines hazelnut orchard design considerations, including density and yield, spacing and arrangement of permanent trees, and loading zones. It also includes a brief description of procedures for establishing a new orchard.
This investigation was motivated by the apparent increase in genetic
variability resulting from the systematic combining of gene pools
represented by winter and spring types of wheats.
It was the objective of this study to provide information regarding
the nature of this genetic variability for nine agronomic characters
in populations...
This thesis advocates the use of maximum likelihood analysis for generalized
regression models with measurement error in a single explanatory variable. This will be
done first by presenting a computational algorithm and the numerical details for carrying
out this algorithm on a wide variety of models. The computational methods will...
A visitor information study was conducted at the USFS Cape Perpetua
Visitor Center during August, 1973. The study sought to develop a visitor profile
and activity analysis to aid in planning future exhibits and interpretive
developments, analyze vacation travel patterns of persons visiting the center,
determine how people chose their...
