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 …
Creative Nonnatives: Painting Invasive Insects Of The United States, Monica Tynan
Creative Nonnatives: Painting Invasive Insects Of The United States, Monica Tynan
Senior Honors Projects
An invasive species is a nonnative organism that may cause damage to an ecosystem. Invasive species cause problems in an environment by outcompeting native organisms for resources or by feeding upon native species. Invasive insects in particular can harm an ecosystem by consuming foliage and decreasing biodiversity. During my experience at the Preisser Lab at the University of Rhode Island, I witnessed rsthand the damage that invasive insects can do to a tree population, and I learned about how ecosystem dynamics can be disrupted by the introduction of a nonnative species.
My project portrays an aesthetically pleasing visualization of several …

Are We Fooling Ourselves??? Eelgrass And Subaqueous Soils As A Refuge For Fecal Indicator Bacteria, Jessie Dyer
Are We Fooling Ourselves??? Eelgrass And Subaqueous Soils As A Refuge For Fecal Indicator Bacteria, Jessie Dyer
Senior Honors Projects
A beach closure during the height of the summer can cost a coastal community approximately $37,000. In 2006, 349 beach closures in Rhode Island were due to presumed human fecal contamination. Fecal contamination is determined based on enumeration of fecal indicator bacteria. Fecal enterococci (FE) are the commonly used indicator bacteria for human fecal contamination in fresh and coastal waters. The EPA has suggested that FE is the best indicator of human health risk in salt water used for recreation and shell fishing activities. Recently, molecular analysis of Bifidobacterium adolescentis has been introduced as a more reliable, specific indicator of …
The Effects Of Tail Flukes On The Swimming Pattern Of Atlantic Bottlenose Dolphins, Lauri Leach
The Effects Of Tail Flukes On The Swimming Pattern Of Atlantic Bottlenose Dolphins, Lauri Leach
Senior Honors Projects
Atlantic bottlenose dolphins are top predators in the wild, due in part because they are excellent swimmers. When dolphins swim through the water, the tail flukes are moved in an up and down motion to propel the animal through the water. They use the pectoral fins for steering and braking, and the dorsal fin for stabilization as they swim. Using this style of swimming, Atlantic bottlenose dolphins can swim up to 25 miles per hour and leap 15 to 20 feet into the air.
During the spring of 2008, I was an intern at the Clearwater Marine Aquarium in Florida. …
Factors Influencing Interactions Between Ticks And Wild Birds, Amy A. Diaz
Factors Influencing Interactions Between Ticks And Wild Birds, Amy A. Diaz
Senior Honors Projects
Lyme disease, a tick-borne bacterial illness, is the most common vector-borne infection in north temperate areas worldwide. Ticks, while minute in size, can be competent vectors of both human and animal diseases. Upon hatching, larvae must take a blood meal in order to transform into the next life stage. When taking this first blood meal, the larval tick may ingest blood containing pathogens. If this occurs, the newly emerged nymphal tick is capable of transmitting infection to the next host, which can become infected and, if reservoir competent, infective. When the pathogen carrying vector is attached long enough, a host …
Time Post-Hatch Caloric Value Of Artemia Salina, Jessie M. Sanders
Time Post-Hatch Caloric Value Of Artemia Salina, Jessie M. Sanders
Senior Honors Projects
In aquatic animal collections, such as those in the collection of Mystic Aquarium & Institute for Exploration’s Fish & Invertebrate department, live food is an essential part of the diet of animals that are on display, used in education, and kept in reserve for exhibits. For Mystic Aquarium’s Fish & Invertebrate department, newly hatched Artemia salina, or brine shrimp, are fed to an assortment of fishes and invertebrates, including soft corals and jellyfish. Hatch brine is an important source of fatty acids, which are essential for proper growth and development. Hatch brine starts encapsulated in a cyst form and are …
Importance Of Early Successional Forest For Wildlife In Southern New England, Amy Wynia
Importance Of Early Successional Forest For Wildlife In Southern New England, Amy Wynia
Senior Honors Projects
Many bird species that require early successional forest are declining in the Northeast U.S. because such habitat is relatively rare and when they inhabit the more common mature forests or suburban areas they are less successful. Early successional forest is maintained by regular disturbance (wind, fire, clear-cutting, and flooding) which has been happening less frequently during the past 50 years. Bird species that have declined during this time and which inhabit early successional forest include ruffed grouse (Bonasa umbellus), blue jay (Cyanocitta cristata), chestnut-sided warbler (Dendroica pensylvanica), gray catbird (Dumetella carolinensis), field sparrow (Spizella pusilla), golden-winged warbler (Vermivora chrysoptera), eastern …
