Social Behaviors Of Modern And Indigenous Peoples Impacting The Ecology Of The Amazon Rain Forest In Brazil, Josef W. Schaffer

Earth and Soil Sciences

Human induced disruption of the environment is prevalent in every culture. In Brazil, the effects of massive deforestation have become apparent since the nineteen eighties. However, along with deforestation, and a coinciding loss in an economic resource for the country, is a significant loss of natural habitat and species extinction. The Amazon in Brazil contains a large proportion of the world’s species diversity that is threatened by the socio-economic activities of modern Brazilian culture. Historically and presently, indigenous groups have contributed to insignificant levels of ecological disruption and are themselves threatened by the activities of modern Brazilians. The effects of …

Development Of Regional Hydraulic Geometry Curves For The Santa Cruz Mountains, Sarah Howell

Natural Resources Management and Environmental Sciences

This study was conducted to develop regional hydraulic geometry curves for the Santa Cruz Mountains that could be used in stream related and/or engineering projects. Data used to form these curves was collected from the USGS and by conducting stream geometry surveys. The resulting regional curves had high R² values ranging from .82 to .92. Compared to other regional curves in nearby areas, the Santa Cruz Mountains regional curve equations have higher exponents, meaning bankfull channel measurements increase at faster rates as drainage areas increases. Further measurements and analysis should be done before applying these curves to project sites.

Acid Rain: The Effects, Torrey Mortimer

Social Sciences

In a world experiencing increasing population, urbanization, and developing nations looking to compete on a global market with post-industrial nations, the effects of acid precipitation require greater consideration. As the world’s energy demand rises, and with the cheapest and most abundant source of energy being coal, the occurrence of acid precipitation is on the rise.

The goal of my project is to research and report on the effects of acid deposition on humans, animals and the environment that surrounds them. When I have completed my project, I hope to be able to explain the impacts that acid deposition has on …

Tall Fescue (Lolium Arundinaceum (Schreb.) S.J. Darbyshire) Cultivar Performance In The Central California Coastal Region, Seril Shimizu

Master's Theses

Tall fescue (Lolium arundinaceum (Schreb.) S.J. Darbyshire) has long been known as a turfgrass that utilizes lower levels of inputs than most other cool season turfgrasses (Turgeon, 2005). In recent years, turf breeders have been selecting for cultivars of tall fescue that have finer leaf textures. As the use of tall fescue expands, consumers want to now what cultivar to use and how to manage it. This study looked at 18 tall fescue cultivars grown at two mowing heights of five and 10 centimeters and evaluated plant quality based on stand density, leaf texture, and genetic plant color. In the …
