Degradation of watersheds is a major concern in areas where adverse climate effects and unsustainable use of the natural resources have caused extensive stresses to watershed systems (e.g., increased floods, increased droughts, worsened in-stream water quality) through the years. While considerable efforts are being made to generate technical solutions that...
This paper focuses on investigating (a) how landowner tenure and attitudes of farming communities affect the preference of individual conservation practices in agricultural watersheds, (b) how spatial distribution of landowner tenure affects the spatial optimization of conservation practices on a watershed scale, and (c) how the different attitudes and preferences...
Climate-driven changes in biotic interactions can profoundly alter ecological
communities, particularly when they impact foundation species. In marine systems,
changes in herbivory and the consequent loss of dominant habitat forming species can
result in dramatic community phase shifts, such as from coral to macroalgal
dominance when tropical fish herbivory decreases,...

This report describes the state of the California Current System (CCS)—meteorological, physical, chemical, and biological—from January 2003 to the spring of 2004. The area covered in this report ranges from Oregon coastal waters to southern Baja California. Over the past year, most physical, chemical, and biological parameters were close to...
In the contemporary United States, the process of "coming out of the closet," or public disclosure of one's non-normative sexual orientation or gender identity, is ongoing and performative. Particularly within the context of dominant contemporary U.S. society, popular media favors a hegemonic set of defining characteristics, which thereby forces the...
Latinos are the fastest growing minority group in the U.S. and are expected to be 25% of the population by the year 2050. Latinos also are more vulnerable and at higher risk for poor health outcomes including diabetes and other chronic health ailments than Anglos. Many of the serious effects...
A split-rooted containerized system was developed by approach grafting two, 1-year-old apple (Malusxdomestica Borkh. cv 'Gala') trees to investigate the effect of soil moisture heterogeneity and total soil moisture content (θv) on tree water relations, gas exchange, and leaf abscisic acid (ABA) concentration [ABA[subscript leaf]]. Four irrigation treatments comprising a...
Entomopathogenic fungi are cosmopolitan microbial pathogens that cause fungous diseases in a wide range of insects via spore infection. Due to their natural enemy status, they have tremendous potential for use as microbial control agents against insect pests, especially subterranean pests for which few management options are available. The clover...
