Falcons Using Orchard Nest Boxes Reduce Fruit-Eating Bird Abundances And Provide Economic Benefits For A Fruit-Growing Region, Megan E. Shave, Stephanie A. Shwiff, Julie L. Elser, Catherine A. Lindell

United States Department of Agriculture Wildlife Services: Staff Publications

1. Suppression of pest species via a native predator is a regulating ecosystem service that has the potential to limit crop damage and produce economic benefits. American kestrels Falco sparverius are widespread, highly mobile, generalist predators that hunt in human-dominated habitats and have the potential to provide previously undocumented ecosystem services in agricultural landscapes.

2. We hypothesized that kestrel activity associated with nest boxes and artificial perches acts to increase perceived predation risk that, in combination with direct predation, can reduce fruit-eating bird abundances in orchards. We used counts and observations of fruit-eating birds from fixed-width transect surveys to investigate …

Four Legs Good, Two Legs Bad: How Slaughterhouse Safety Hasn’T Kept Up With The Times, Emily Ziemski

Capstones

From legal loopholes and outdated rules to undetectable infections and understaffing, the United States Department of Agriculture may not be doing all it can to make sure the American public’s health isn't at risk. As the people of the United States consume over 500 million pounds of beef a year, food safety policy and slaughterhouses are falling behind in proper procedural measurements in the beef industry.

Avian Diversity, Abundance, And Nest Success Among Managed Prairies And Agricultural Plots In Oklahoma And Texas, Phillip J. Leonard, Douglas R. Wood, Wayne E. Meyer

The Prairie Naturalist

Over the last 50 years, grassland birds experienced rapid declines due to habitat loss and degradation as a result of agricultural practices. Our objective was to document the diversity, abundance, and nest success of bird communities using managed prairie and agricultural plots at the Tishomingo National Wildlife Refuge (NWR) in southern Oklahoma and Hagerman NWR in northern Texas. From April 1 to July 15, 2013–2014, point count surveys, nest searches, nest monitoring, and vegetation sampling were conducted among three habitat treatments: managed prairie, unharvested wheat, and fallow agricultural plots. Species richness values for potential nesting species were higher in managed …

Accounting For Soil Inorganic Carbon In The Ecosystem Services Framework For United Nations Sustainable Development Goals, Garth Raymond Groshans

All Theses

Soil inorganic carbon (SIC) is currently not included in the list of key soil properties related to ecosystem services (e.g., provisioning, regulating, cultural, and supporting services). Soil inorganic carbon is a dynamic key soil property used in soil classification, taxonomy and fertility, therefore its inclusion in the framework of ecosystem services is important. With soils rapidly changing due to human use and climate change, the soil ecosystem services framework should not include only soil organic carbon (SOC), but SIC as well since it is of global importance to soil fertility and the long-term carbon cycle, especially in semiarid and arid …

Phosphorus Retention In West Michigan Two-Stage Agricultural Ditches, Emily Kindervater

Masters Theses

Input of excess nutrients into a water body can negatively impact ecological structure and function, as well as the economic vitality of surrounding communities, by contributing to eutrophication. For example, phosphorus (P) and sediment inputs from agricultural drainage have facilitated the development of hypereutrophic conditions in Lake Macatawa, a drowned river mouth lake located in Holland, Michigan. Two-stage ditches, an agricultural best management practice (BMP), are used in some areas of the Midwest to reduce N export downstream via denitrification. This BMP simulates a mini-floodplain by replacing a traditional, trapezoidal ditch with a channel that has excavated benches on each …

The Economic Benefits Of The South African Agricultural Research Council’S Wheat Breeding Program: 1992–2015, Matthew James Coale

Graduate Theses and Dissertations

Although classified as an upper middle-income country by the World Bank, food insecurity is still a concern throughout South Africa, as was evident in 2014–2015 when a drought left 22% of households food insecure. As such, agricultural research in South Africa is needed specifically in plant breeding to increase yields and help mitigate future food insecurity. To fill this need, the South African government funds the Agricultural Research Council (ARC), which conducts holistic research on wheat and other crops. Wheat is important to South African food security; due to the significant drop in wheat area planted since the abolishment of …

A Comparative Life Cycle Assessment Of Nutritionally Equivalent Meals With And Without Pork, Kelli Young

Graduate Theses and Dissertations

The following report details a life cycle assessment of several dietary and meal scenarios with and without pork. The goal of the LCA was to identify the impacts of greenhouse gas emissions, water use, and land use of pork containing and porkless diets and meal plans in a field-to-fork analysis. The dietary and meal plan scenarios are iso-caloric meaning they contain the same number of calories. The first set of diets is based on a USDA consumption pattern, 2000 kcal per day. This diet was used to create three other dietary scenarios with and without pork. The USDA recommended food …

Atay V. County Of Maui, Stephanie A. George

Public Land & Resources Law Review

As genetically engineered plants become more common, questions frequently arise regarding how the plants are regulated and who can regulate them. The Ninth Circuit attempted to answer these questions through preemption doctrine. The court left the door open for states and localities to regulate genetically engineered crops that have been deregulated by the federal government. This decision will implicate the future cultivation of genetically engineered crops, and the food industry as a whole.

Organic Solvent Exposure And Depressive Symptoms Among Licensed Pesticide Applicators In The Agricultural Health Study, Miriam Siegel, Sarah E. Starks, Wayne T. Sanderson, Freya Kamel, Jane A. Hoppin, Fred Gerr

Epidemiology and Environmental Health Faculty Publications

Purpose

Although organic solvents are often used in agricultural operations, neurotoxic effects of solvent exposure have not been extensively studied among farmers. The current analysis examined associations between questionnaire-based metrics of organic solvent exposure and depressive symptoms among farmers.

Methods

Results from 692 male Agricultural Health Study participants were analyzed. Solvent type and exposure duration were assessed by questionnaire. An “ever-use” variable and years of use categories were constructed for exposure to gasoline, paint/lacquer thinner, petroleum distillates, and any solvent. Depressive symptoms were ascertained with the Center for Epidemiologic Studies Depression Scale (CES-D); scores were analyzed separately as continuous (0–60) …

Agricultural Intensification Can Preserve The Brazilian Cerrado: Applying Lessons From Mato Grosso And Goia's To Brazil’S Last Agricultural Frontier, Stephanie A. Spera

Geography and the Environment Faculty Publications

Food security and climate change are two pressing issues shaping the future of tropical land use. Brazil, home to abundant land that is rich in carbon, water, and biodiversity and often cleared for agropastoral and renewable energy purposes, is the ideal location for studying socioeconomic and environmental trade-offs of land use dynamics. Here, I use recent (2000–2016) land-use land-cover change dynamics in the established agricultural states of Mato Grosso and Goia's to demonstrate how incentivizing intensive agricultural practices and improving degraded pastures may be a means by which Brazil can increase agricultural production while conserving the remainder of the Cerrado. …
