Functions Of Ecosystems: Stream Metabolism As An Efficient And Effective Means To Gage The Health And Understand The Interworking Of Urban Streams In A Watershed Of Rock Island, Il, Ryan Johnson, Dr. Kevin Geedey
Functions Of Ecosystems: Stream Metabolism As An Efficient And Effective Means To Gage The Health And Understand The Interworking Of Urban Streams In A Watershed Of Rock Island, Il, Ryan Johnson, Dr. Kevin Geedey

Stream metabolism is a critical functional measure of stream health that integrates physical parameters like slope and discharge, with ecosystem functions like photosynthesis and respiration. Stream metabolism is widely studied; however, urban stream metabolism remains poorly understood. Stream metabolism was measured for five streams ranging from 1st to 5th orders from October 11th to October 18th 2017 and four streams ranging from 1st to 4th order from October 22nd to 25th 2017 located within an approximately 9.3 square kilometer watershed of Rock Island, IL that has an urban to suburban type of …
A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum
A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum

Urban expansion has had devastating impacts on forest ecosystems, especially within the past century. Human attempts to dominate nature have diminished natural disturbance regimes, which have maintained the biodiversity and historic composition of these ecosystems. Fires have been a prominent force in maintaining the structure of oak, hickory and other heliophytic (sun loving and fire-adapted) forest systems. Human induced fire suppression has led to mesophication across North America. Mesophication is the transition from drier conditions with open canopies to wetter conditions with closed canopies. These new conditions decrease the survival rates of these important species and begin to favor mesophytic …
Outdoor Air Quality, Taylor Curley
Outdoor Air Quality, Taylor Curley
Global Issues in Public Health
Outdoor air quality is a significant issue for the entire world. It affects any and all people, but is more of an issue in low-income countries and among people that are more susceptible to respiratory issues such as young children, pregnant women, the elderly, and people who already suffer from respiratory problems like asthma. Poor air quality is caused by the burning of fossil fuels which releases particles and chemicals into the air like carbon dioxide, particulate matter, and nitrogen to name a few. It can cause multiple health issues such as respiratory problems to people who are exposed to …

Type 1 Diabetes, Dan Bornstein
Global Issues in Public Health
The aim of this research was to increase the awareness of this disease and show the range of which it travels. Type 1 Diabetes, although not as common as Type 2 Diabetes, is a very serious disease present well around the world. Between the two forms, there are nearly 1.5 million people diagnosed with diabetes each year (American Diabetes Association, 2015). Northern European countries tend to have the highest prevalence of Type 1 diabetes. Younger children on average ages of 0-14 years, are most frequently struck with this disease (American Diabetes Association, 2015). With the given amount of symptoms that …
Trap-Neuter-Return Programs And The Importance Of Associated Public Awareness, Nicolette Sliwa
Trap-Neuter-Return Programs And The Importance Of Associated Public Awareness, Nicolette Sliwa
Biology: Student Scholarship & Creative Works
The focus of this paper is to describe a typical Trap-Neuter-Return (TNR) program and highlight the major pros and cons surrounding this somewhat controversial method of managing the overwhelming free-roaming cat population. The effects of the species’ overabundance on the environment and human health are also discussed. Citing studies completed on TNR programs around the globe as well as mathematical models, the effectiveness of this method is compared to other, currently used alternatives. Finally, it has been suggested that the general awareness level a neighborhood possesses about the true goals of TNR programs has a potentially significant impact on the …

Evaluating Trophic Rewilding As A Conservation Technique, Aaron Sieve
Biology: Student Scholarship & Creative Works
The focus for this paper is to define specifically trophic rewilding, determine its efficacy as a conservation technique, and explore ways to lessen one of its key limitations. Trophic rewilding is the conservation technique whereby an extirpated keystone species or ecosystem engineer is reintroduced into a degraded habitat to restore ecological function by triggering trophic cascades. The technique is evaluated through analysis of the concepts of trophic cascades and ecosystem engineers. Key limitations of trophic rewilding are that a lack of population control in reintroduced may cause issues, that many times not enough is known about trophic cascades to be …

Hiv Vaccines: Progress, Limitations And A Crispr/Cas9 Vaccine, Omar A. Garcia Martinez
Biology: Student Scholarship & Creative Works
ABSTRACT: The HIV-1 pandemic continues to thrive due to ineffective HIV-1 vaccines. Historically, the world’s most infectious diseases, such as polio and smallpox, have been eradicated or have come close to eradication due to the advent of effective vaccines. Highly active antiretroviral therapy is able to delay the onset of AIDS but can neither rid the body of HIV-1 proviral DNA nor prevent further transmission. A prophylactic vaccine that prevents the various mechanisms HIV-1 has to evade and attack our immune system is needed to end the HIV-1 pandemic. Recent advances in engineered nuclease systems, like the CRISPR/Cas9 system, have …
Impacts From The Use Of Antibiotics In Livestock: Methods Of Transmission Of Antibiotic Resistance From Livestock To Humans, Kristin M. Walden
Impacts From The Use Of Antibiotics In Livestock: Methods Of Transmission Of Antibiotic Resistance From Livestock To Humans, Kristin M. Walden
Biology: Student Scholarship & Creative Works
Antibiotic use in livestock production has been around since the 1950s. Antibiotic feed is used in livestock and other meat producing animals for three reasons: illness prevention, illness treatment, and growth promotion. Unfortunately, since the time that antibiotics were first invented, antibiotic resistant bacteria have become a threat to public health. There are many studies showing methods of transmission of antibiotic resistance from livestock to humans. Antibiotic resistance can spread from livestock to soil, water, insects, and food, which ultimately comes into contact with humans. A proposed study to measure antibiotic resistance when eliminating antibiotic feed will provide a hypothesis …
