Bringing The Endangered Barn Owl Back To Mclean County, Illinois: Implementing A Local Nest Box Program, Anna Groves '11
Bringing The Endangered Barn Owl Back To Mclean County, Illinois: Implementing A Local Nest Box Program, Anna Groves '11
Outstanding Senior Seminar Papers
Barn owls are an endangered species in Illinois, but populations have been known to increase where nest box programs have been implemented. In conjunction with the John Wesley Powell Audubon Society, a barn owl nest box program was established in McLean County and the surrounding area. Seventeen boxes are now scheduled for construction and installation this winter in the McLean County area in order to enhance existing barn owl populations, and the nest box program will continue in the future through the JWP Audubon.

The Dickey Bird Scientists Take Charge: Science, Policy, And The Spotted Owl, Thomas R. Wellock
The Dickey Bird Scientists Take Charge: Science, Policy, And The Spotted Owl, Thomas R. Wellock
History Faculty Scholarship
In 1992, the Forest Service adopted a new operating policy, Ecosystem Management, which minimized the agency's timber production goals in favor of a more ecologically balanced view of its responsibilities. In explaining this shift, scholars have dismissed the possibility of internal reform, arguing that the Service could not change without irresistible external pressure from environmental activists and new public values supporting biodiversity. Viewing the Service's shift through the lens of the spotted owl controversy, however, demonstrates the important role agency culture played in instigating bureaucratic change. The Service's evolution stemmed from the rising influence of its scientists in policy formation. …
Seasonal Variation In Terrestrial Insect Subsidies To Tropical Streams And Implications For The Diet Of Rivulus Hartii, David C. Owens
Seasonal Variation In Terrestrial Insect Subsidies To Tropical Streams And Implications For The Diet Of Rivulus Hartii, David C. Owens
School of Natural Resources: Dissertations, Theses, and Student Research
Terrestrial invertebrates subsidize fish diets in lotic ecosystems. Seasonality strongly influences terrestrial invertebrate abundance in temperate regions and alters their delivery to streams. Seasonal changes in the tropics are characterized by distinct wet and dry periods, with marked variation in invertebrate abundance. However, little is known about how these seasonal changes affect invertebrate subsidies and their ecological consequences for tropical streams. We measured the effect of rainfall and canopy density on terrestrial invertebrate falling input, as well as seasonal variation in falling input, benthic and drifting invertebrate, and Rivulus hartii (Hart’s Rivulus) diet composition during both the wet and dry …
Facilitating Behavior Change Of Coastal Communities In Regards To Climatic Hazards, Marisa Nixon
Facilitating Behavior Change Of Coastal Communities In Regards To Climatic Hazards, Marisa Nixon
Senior Honors Projects
For my Senior Honors Project I participated in the Climate Change Collaborative, which is a new interdisciplinary research project studying the ways in which coastal communities in Rhode Island can better adapt to the environmental, cultural and economic consequences of climate change. As a member of this collaborative, I worked in a vertically integrated team of faculty (psychology researchers, climate scientists and communications science practitioners and researchers) as well as undergraduate and graduate students, to begin an endeavor through which behavior change will be assessed in regards to climate change. For the purposes of this study, we specifically focus on …
A South County Almanac: Recollections And Observations Of The Outdoors In Southern Rhode Island, Nevan Richard
A South County Almanac: Recollections And Observations Of The Outdoors In Southern Rhode Island, Nevan Richard
Senior Honors Projects
Since its publication in 1949, “A Sand County Almanac: With Sketches Here and There” has served as the benchmark for writing about the environment and nature. “Sand County” was written by famed environmentalist Aldo Leopold, who for most of his lifetime worked towards the conservation of wildlife and natural resources. In “Sand County,” Aldo Leopold recounts his experiences and observations in various essays and journal entries from his many years of living in Wisconsin, as well his travels across the North American continent. With its publication after Mr. Leopold’s death, it changed the face of the American conservation movement, later …
Influence Of Canopy Cover, Nutrients, And Season On Stoichiometric Variation Of Epilithon In Neotropical Streams., Tyler J. Kohler
Influence Of Canopy Cover, Nutrients, And Season On Stoichiometric Variation Of Epilithon In Neotropical Streams., Tyler J. Kohler
School of Natural Resources: Dissertations, Theses, and Student Research
Light and nutrient availability are strong factors determining the nutrient composition of epilithon in temperate stream ecosystems. However, little work has been performed regarding this association in tropical streams. In our study, we investigated 1) how gradients of canopy cover and nutrients and 2) wet/dry seasonality influence epilithon standing stocks and nutrient quality. We surveyed 18 stream locations within six watersheds that varied in nutrient and light conditions during both the wet and dry seasons on the island of Trinidad to test these questions. Additionally, we sampled four stream reaches bimonthly for three years, thinning the canopy of two of …

Impacts Of Shoreline Development On The Littoral Zone Of Great Pond, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College
Colby College Watershed Study: Great Pond (2012, 2010, 1998)
The Colby Environmental Assessment Team (CEAT) investigated the littoral zone of Great Pond in the Belgrade Lakes region of central Maine. Data collection occurred in September and October and analysis followed in October and November of 2010. Physical, biological, and chemical parameters were assessed to examine the impacts of shoreline development on the health of the littoral community. The littoral zone and adjacent riparian areas were sampled to allow comparison of aquatic and terrestrial parameters among different levels of shoreline development.

Micro-Environment And Plant Assemblage Structure On Virginia's Barrier Island "Pimple" Dunes, Brett A. Mcmillan, Frank P. Day
Micro-Environment And Plant Assemblage Structure On Virginia's Barrier Island "Pimple" Dunes, Brett A. Mcmillan, Frank P. Day
Biological Sciences Faculty Publications
“Pimple” dunes are small, rounded coastal dunes that form along major dune ridges of the barrier islands along the Eastern Shore of Virginia. Although most pimple dunes are small structures ranging between 10 and 20 m in diameter, they have distinct plant assemblages that replicate the upland ecotones of their barrier islands. We examined the relationship between microenvironment, edaphic factors, and plant assemblage structure on pimple dunes. Water availability was an obvious major ecological driver, but we also tested other environmental factors that may correlate with plant assemblage structure. We found distinct assemblage types that segregated themselves by habitat type: …

A Functional And Ontogenetic Skull Analysis Of The Extant Rhinoceroses And Teleoceras Major, An Extinct Miocene North American Rhinoceros, Mark Daniel Hagge
LSU Master's Theses
Functional and ontogenetic skull differences among extant rhinoceroses and the extinct North American rhinoceros Teleoceras major were investigated to assess the unknown feeding ecology of Teleoceras. Ontogenetic skull sequences of the extant Indian rhino (Rhinoceros unicornis), Sumatran rhino (Dicerorhinus sumatrensis), white rhino (Ceratotherium simum), and black rhino (Diceros bicornis), and the extinct Miocene North American rhino T. major were gathered for both qualitative and quantitative assessments. Eleven functional characters related to specific feeding ecologies in extant perissodactyls were morphologically described, and each species’ skull development was described in detail. Nineteen linear skull measurements were taken across all specimens of all …
