The Effects of Nitrogen Fertilization of Wheatgrass on the South American Locust (Schistocerca cancellata)

Description

Locusts are a major crop pest in many parts of the world and different species are endemic to different countries. In Latin America, the South American Locust (Schistocerca cancellata) is the predominant species found mostly in Argentina, Chile, Bolivia, Paraguay,

Locusts are a major crop pest in many parts of the world and different species are endemic to different countries. In Latin America, the South American Locust (Schistocerca cancellata) is the predominant species found mostly in Argentina, Chile, Bolivia, Paraguay, and southern Brazil with Argentina being the most affected. Several control and management practices, including biological control, have been implemented in these countries in the past to control the locusts and reduce their impact on crop and vegetation, however, effective long-term control and management practices will require a detail understanding of how the predominant locust species in this region responds to resource variation. Research has shown that there is strong evidence that locusts, and many other organisms, will actively balance dietary macronutrients (protein, carbohydrates, and lipids) to optimize growth, survival, and/or reproduction. A study by Cease et. al, 2017, on the dietary preferences of the Mongolian locust (Oedaleus asiaticus) showed that it prefers diets that are high in carbohydrates over diets that are high in protein, in this case locusts self-selected a 1:2 ratio of protein:carbohydrate. This and many other studies provide vital insight into the nutritional and feeding preferences of these locust species but the effects that this difference in protein: carbohydrate preferences has on growth, egg production, flight potential, and survival has yet to be fully explored, hence, this study investigates the effects that nitrogen fertilization of wheatgrass will have on the growth, egg production, survival, and flight muscle mass of the South American locust in a controlled, laboratory environment.

This paper analyzes the Flint, Michigan water crisis through research of water treatment in the United States. Pertinent scientific information is provided to serve as a background from which the reader can draw from to best understand the situation. The significance of water treatment in the context of sustainability is demonstrated through this descriptive case study of Flint. In ongoing efforts to supply safe drinking water to all communities, the comprehension of how the national framework works and why water is treated is paramount. Through the lens of society, this paper examines the science of water pollution, water treatment, treatment issues, and ensuing consequences. Water is a critical finite resource, and understanding how to most effectively use this limited resource is a major goal of the sustainable agenda.

Teaching Sustainability with Goats in Grenada: Informal Education and the Formal Classroom

Although sustainability as a concept and a science has been around for quite some time, it has only recently come into the common vernacular of citizens around the world. While there are a number of arguments that have been and can be made about the role of sustainability in developing countries, it can be said with certainty that sustainability education, especially at the pre-university level, is commonly neglected even in countries that have sustainability initiatives elsewhere in their systems. Education is an important part of development in any country, and sustainability education is critical to raising generations who are more aware of the connections in the world around them. Informal education, or education that takes place outside of a formal classroom, can provide an especially important platform for sustainability ideas. These factors take on unique characteristics within the environment of a small island with noble sustainability goals but limited resources and an economy that includes a significant domestic goat population. After providing basic background on sustainability and the nature of the educational process within the environment of the small island-nation of Grenada, I discuss the importance of informal education and follow my path with a local non-profit in Grenada leading to the development of a locally-relevant sustainability curriculum for implementation in a K-6 school.

This ethnographic study explores the music festival phenomenon in the context of the Austin City Limits music festival, held in Austin, Texas with a total attendance of over 450,000 people annually. Using Glaser and Strauss' grounded theory method (1967), central questions concerning structure, community identity, sustainable consumption, and waste were generated from the ethnography. These topics were analyzed with supporting theory in cultural anthropology, sociology, and sustainability. The findings are the basis for our "local-washing" theory, suggesting that localness is utilized to create a sense of authenticity. It is our shared conclusion that local-washing is a prevalent phenomenon at the modern music festival and presents the impact of commercialization on the public sphere. The research conducted includes collecting ethnographic fieldnotes pertaining to festival-goers behaviors that we observed at the festival as well as an investigation of the waste at the festival. By attending the Austin City Limits music festival and utilizing the ethnographic research method, we gained a deeper understanding of what motivates and bonds people in the unique context of the music festival. Through this we found basis for an analysis of the sustainable consumption of food and beverages at the festival as well as waste behaviors and theories behind them including the idea of waste having an absent presence in society.

Flame retardant contamination in seafood and its significance for conservation

Consumption of seafood poses a substantial threat to global biodiversity. Chemical contamination found in both wild-caught and farmed seafood also presents significant health risks to consumers. Flame retardants, used in upholstery, plastics, clothing, and other products to reduce fire danger, are of particular concern as they are commonly found in the marine environment and permeate the tissues of fish that are sold for consumption via multiple pathways. By summarizing various metrics of sustainability and the mercury content in consumed species of fish and shellfish, researchers have found that high levels of chemical contamination was linked with lesser fishery sustainability. I conducted a literature review of flame retardant content in seafood to further compare contamination and sustainability in addition to the initial analysis with mercury. My review suggests that the widespread issue of fishery collapse could be alleviated by demonstrating to stakeholders that many unsustainable fish stocks are mutually disadvantageous for both human consumers and the environment. Future research should address the need for the collection of data that better represent actual global contaminant concentrations in seafood.

The goal of this research was to analyze the impact of consumer behavior on the sustainability of the fast fashion industry, specifically in regards to the framework of the Triple Bottom Line. First, a review of relevant literature investigating the three aspects of the Triple Bottom Line (environmental, social, and economic) as it pertains to the fast fashion industry was conducted to provide context for this research. Research methods utilized scholarly articles and journals along with companies’ CSR reports to determine the course of development of the fast fashion industry over time. Additionally, the impact of consumer behavior was investigated and linked to trends observed in the production and business practices of the industry over time. Based on the analysis of the influence of past consumer behavior on the industry, it was clear consumers play a major role in the industry and its sustainability in terms of the Triple Bottom Line. This suggests that the unsustainability of the fast fashion industry is due in part to consumer behavior and the retailers themselves, which is important to understand for the industry going forward as it aims to improve overall sustainability.

The objective of this study was to evaluate sustainability knowledge and practices in place at university-associated food pantries across the United States. A survey was sent to university- associated food pantries and responses were collected at a rate of 25% (n=84 of 326) to assess the knowledge and practices of this topic. The pantries surveyed were chosen solely based on ability to contact through email (emails were retrieved from online sources) and about 50% of the 680 university-associated pantries in the United States were sent the survey. The data was analyzed by quantifying the qualitative responses to the 9 sustainability- rated questions addressing zero- waste practice, barriers to offering sustainably sourced foods, types of sustainable donations, desire for sustainable products, and client demand for sustainable products and practices were posed to pantries. Results from this study provided insight into awareness of sustainability in these pantries and also assessed what sustainability practices are already being practiced by these pantries. Among those surveyed, a low percentage of university-associated pantries actually provide sustainably sourced foods (9.5%), but given the choice about a third (38.1%) would choose to offer these foods. It was reported that availability and cost were perceived as main barriers to providing sustainably sourced foods and that a small proportion of pantries teach their clients about zero waste practices, compost, and recycling. There is little client concern about this issue. Most pantries reported recycling more often than composting and also reported participating in some zero-waste practices. These results are unique to this study as not much research has been done in this area to assess environmental sustainability awareness in university-associated food pantries. Further research is required to further evaluate pantries across the nation as this sample size is approximately 12% of all university- associated pantries in the United States.
