Impacts Of Land-Cover Change And High Rainfall On Soil Erosion Among Three Farms In Cerro Punta, Chiriquí, Panamá., Madeline Happ
Impacts Of Land-Cover Change And High Rainfall On Soil Erosion Among Three Farms In Cerro Punta, Chiriquí, Panamá., Madeline Happ
Independent Study Project (ISP) Collection
Soil erosion is a key source leading to the depletion of Earth’s natural resources. Beginning with deforestation, soils are stripped of their rich vegetation cover, leaving them vulnerable to wind, water, and sometimes total exhaustion. One of the major causes of deforestation, if not the primary cause, is for agricultural purposes. Extensive agricultural fields, steep slopes, and heavy rains characterize the highlands of Chiriquí; thus, the land displays potential for severe loss of soil. This paper illustrates and discusses the extent of soil erosion in Cerro Punta, Chiriquí, specifically considering the steep terrains and very wet environment that impact the …

Connecting Through Consilience: Ecology, Society, Culture And Technology, Ruth Mirams, Alexander Hayes
Alexander Hayes Mr.
Amongst linguistic, cultural and geographic diversity, humanity is characterised by inquisitiveness, communication and a deep desire to connect with each other. Despite our advanced intelligence and technological capacity, we are creatures of nature - a species which occupies a habitat, depends on consumable resources and fragile in many ways. As a species, we currently face challenges including overpopulation, diminishing resources and habitat degradation. In essence, we are exhausting the resources we depend on. [1] Resource depletion, disruption, famine, growth and sustainability are all observable in other species and natural systems. Human societies and systems can be described through the same …
Affluent Populations And Their Effect On Biological Diversity Through The Consumption Of Meat, Electronics, And Motor Vehicles, Melody Flores
Affluent Populations And Their Effect On Biological Diversity Through The Consumption Of Meat, Electronics, And Motor Vehicles, Melody Flores
Honors College Theses
The human has caused a far greater impact on the planet's biodiversity than any other species in existence, due to the impact of population, afflluence, and technology. This thesis will argue the importance of biological diversity and how affluent populations are reducing biodiversity through the consumption of meat, electronics, and motor vehicles. Aldo Leopold's "The Land Ethic" and Herman Daly's "The Impossibility Theorem", among others, create a rubric evaluating human activities and provide alternative views on economic impossibilities. Consumption is reviewed from an ecocentric perspective, a holistic outlook placing emphasis on the ecosystem. The reader will become cognizant of their …
The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman
The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman
Honors Projects
Lake Erie has experienced harmful algal blooms with increased frequency since the mid-1990s due to excess nutrients from Rivers, such as the Maumee River, and largely agricultural watersheds. Nonpoint source pollution from agriculture contributes to eutrophication, algal blooms, and the degradation of water quality. This creates stress on aquatic fauna, reduced aesthetic quality, odor, and limits of the water for usage of drinking, recreation, and industry. This research paper asks what the contributions of having access to manure application records, soil records, and information about antibiotics have on what is known about manure management and antibiotic resistance, which has been …
The Role Of Surface Chemistry In The Toxicity Of Manufactured Cerium Dioxide Nanomaterials To Caenorhabditis Elegans, Emily Kay Oostveen
The Role Of Surface Chemistry In The Toxicity Of Manufactured Cerium Dioxide Nanomaterials To Caenorhabditis Elegans, Emily Kay Oostveen
Theses and Dissertations--Plant and Soil Sciences
Manufactured CeO2 nanomaterials (CeO2-MNMs) are used for a wide variety of applications including diesel fuel additives and chemical/mechanical planarization media. To test the effects of CeO2-MNM surface coating charge on to model organism Caenorhabditis elegans, we synthesized 4 nm CeO2 with cationic (DEAE-), anionic (CM-), and neutral (DEX) coatings. In L3 nematodes exposed for 24 hours, DEAE-CeO2 induced lethality at lower concentrations than CM- or DEX-CeO2. Feeding slightly decreased CeO2 toxicity, regardless of coating. In L2 nematodes exposed for 48 hours with feeding, DEAE-CeO2 caused lethality at the …
