AIMS: To investigate the prevalence, molecular type, and antimicrobial susceptibility of Clostridioides difficile in the environment in Vietnam, where little is known about C. difficile. METHODS AND RESULTS: Samples of pig faeces, soils from pig farms, potatoes, and the hospital environment were cultured for C. difficile. Isolates were identified and typed by polymerase chain reaction (PCR) ribotyping. The overall prevalence of C. difficile contamination was 24.5% (68/278). Clostridioides difficile was detected mainly in soils from pig farms and hospital soils, with 70%-100% prevalence. Clostridioides difficile was isolated from 3.4% of pig faecal samples and 5% of potato surfaces. The four …

It is widely assumed that phytoplankton abundance and productivity decline during temperate winters because of low irradiance and temperatures. However, winter phytoplankton blooms commonly occur in temperate estuaries, but they are often undocumented because of reduced water quality monitoring in winter. The small body of in situ work that has been done on winter blooms suggests they can be of enormous consequence to ecosystems. However, because monitoring is often reduced or stopped altogether during winter, it is unclear how widespread these blooms are or how long they can last. We analyzed an over 30-year record of monthly phytoplankton monitoring samples …
Eat Your Invasives: A Practical And Historical Analysis Of Foraging For Invasive Foods, Grace Hartman
Eat Your Invasives: A Practical And Historical Analysis Of Foraging For Invasive Foods, Grace Hartman
Honors Projects
This paper discusses both the historical and modern role of foraging and why people may decide to forage, as well as barriers new foragers may face and how they can be overcome. Furthermore, the paper discusses how foraging for invasive species can be used as a method of conservation and how simple foraging can be encouraged for this reason.
Nexus Between Animal Welfare, Environment, And Sustainable Development: Resource Document, Wellbeing International
Nexus Between Animal Welfare, Environment, And Sustainable Development: Resource Document, Wellbeing International
Nexus – UNEP – Animal Welfare, Environment, Sustainable Development
This Resource Document has been developed to explore the Nexus (links) between Animal Welfare, the Environment, and Sustainable Development. The document includes relevant citations and reports addressing the topics encompassed by the Nexus. It will be maintained as a “living document” (subject to revision) in the WellBeing International Studies Repository. The original document and subsequent revisions will be kept in the Repository to provide a record of the changes.

Understanding the sources of environmental stressors, the role of geology, climate and technology would provide a guide to solving the problems posed by such stressor. The study examine the sources of wastes in Ikhueniro open dumpsite located in Benin city, Nigeria and characterize the leachate emanating from it. This will assist in adequate design of managerial scheme to tackle the menace posed by it while putting into consideration the role of geology, climate and technology. The key objectives are to carry out field study, characterize wastes in the dumpsite and collect raw leachate emanating from the wastes heap in order …
Effectiveness Of Plastic Ordinances In Santa Monica, Ca: Do Regulations At The Municipal Level Reduce Plastic Waste?, John W. Hayes
Effectiveness Of Plastic Ordinances In Santa Monica, Ca: Do Regulations At The Municipal Level Reduce Plastic Waste?, John W. Hayes
School of Public Policy Capstones
Plastic is a cheap, robust and versatile material with numerous practical uses that contribute to the convenience of modern day life. However the very same properties that make it uniquely diverse and hardy also contribute to the hazards it poses to the ecosystems and human health. If current consumption and manufacturing practices remain unchanged, there will be hundreds of millions of additional tons of plastic introduced into the environment over the coming decades. To mitigate this issue, some cities, such as Santa Monica, have implemented ordinances and policies directly aimed at this growing problem, albeit with ambiguous results. To better …

Year-long Analysis of the Water Quality of White Horn Brook
Sponsor: Thomas Boving (Geological Sciences)
Water is the foundation for all life on earth and is the most vital resource on this planet. Despite this, oceans and waterways all over the world are being polluted and exploited in ways detrimental to their fundamental hydrologic functions. For instance, excess nitrate levels can lead to eutrophication which gives rise to harmful algae blooms. Low pH can cause the breakdown of CaCO3 exoskeletons of organisms, such mollusks. High temperature variations are major stressors to living things and can cause …
Mammal Species Inventory Using Various Trapping Methods In Zone 4 Of Billy Barquedier National Park, Belize During Rainy Season, Mersady Redding
Mammal Species Inventory Using Various Trapping Methods In Zone 4 Of Billy Barquedier National Park, Belize During Rainy Season, Mersady Redding
Animal Science Undergraduate Honors Theses
Belize is a small country, but it is extremely ecologically diverse. Based on the few studies conducted in Belize, the abundance of mammals is low but diversity is high. Particular findings note the number and identity of species differed between four sites in the Maya Mountains of Belize, indicating that a data set from a single site is not representative of the Neotropical region. Insufficient data is available to estimate current species richness of many areas in Belize, including Billy Barquedier National Park (BBNP). The objective of this study was to explore trapping and documentation methods of terrestrial mammals in …

What About The Environment?: Exploring The Neglected Third Dimension Of Antimicrobial Resistance, Paige E. Montfort
What About The Environment?: Exploring The Neglected Third Dimension Of Antimicrobial Resistance, Paige E. Montfort
Independent Study Project (ISP) Collection
Antimicrobial resistance (AMR) is one of the most urgent and complex health risks of our time, with links to human health, animal health, and the environment. The majority of research and policy related to AMR, however, has been dedicated to human and animal health. The third dimension — the environment — has been relatively neglected. Conversations about this problem have begun, but gaps in understanding remain. This study explores the key barriers that have hindered developments related to the environmental aspect of AMR and some of the solutions that have begun to or could be utilized to overcome these barriers. …
