Youth depression is a significant and growing international public health problem. Youth who engage in high levels of delinquency are at particularly high risk for developing problems with depression. The present study examined the impact of a behavioral intervention designed to reduce delinquency (Multidimensional Treatment Foster Care; MTFC) compared to...
Drosophila suzukii Matsumura (Diptera: Drosophilidae) utilizes ‘Himalaya’ blackberry, Rubus armeniacus
Focke (Rosaceae), as a host and may invade berry and stone fruit crops from field margins
containing this invasive weed. Laboratory and semi-field studies were conducted to determine (1)
the persistence of protein marks including 10% chicken egg whites (egg...
Preservice teachers' beliefs and values develop due to their long "apprenticeship of observation" (Lortie, 1975) and often filter their teacher education experiences (Feiman-Nemser & Buchman, 1986; Pajares, 1992). Case methods may be one curricular tool by which to instill change in preservice teachers' beliefs and values. This study investigated the...
Histones, as part of nucleosomes, are responsible for DNA packaging in chromosomes. They also affect DNA expression by a multitude of post-translational modifications, especially prevalent on the amino terminus of histones. Co-activator protein complexes “write”, “read”, or “erase” histone modifications, and in balance determine which sections of DNA are free...
Litter nutrient dynamics contribute significantly to biogeochemical cycling in
forest ecosystems. These dynamics may be influenced by site attributes, litter nutrient concentrations, and soil nutrient availability either independently or synergistically. Litter nutrient dynamics were examined in two decomposition studies in temperate coniferous forests of Oregon. I used ¹⁵N-labelled litter of...
On January 8th, 2011 tragedy struck in Tucson, Arizona. A gunman opened fire on Representative Gabrielle Giffords' "Congress on Your Corner" event, wounding thirteen and killing six ("Arizona Shooting"). Four days later, President Obama spoke to a grieving crowd at the University of Arizona's McKale Memorial Center. This study seeks...
Dual-axis accelerometer global positioning system collars can be used to remotely record the activity level and behavior of free-ranging animals, but inter- and intraspecific variations in motion among behaviors necessitate calibration for each species of interest. To date, little work has been done to determine the best duration for sampling...
Disturbances are a prevalent and important part of ecosystems. Many landscape patterns that we find today were created, maintained, and changed by natural disturbance regimes. This is especially true for fire, which has historically been a common, natural disturbance in the western U.S forests and grasslands and many other parts...
