Automated Photo-Identification Of Cetaceans : An Integrated Software Solution, Daniel Griggs Jan 2006

Automated Photo-Identification Of Cetaceans : An Integrated Software Solution, Daniel Griggs

Theses : Honours

This study investigates current techniques used for automated photo-identification of cetaceans (i.e. dolphins and whales). The primary focus constitutes various techniques that can be applied to identify and extract dorsal fins from digital photographs. A comprehensive analysis of these techniques demonstrates the most effective software solution. To further support this analysis, four prototypes are developed to demonstrate the effectiveness of each technique in a practical environment. The analysis bases its final conclusions on test results generated from these prototype software examples. Final conclusions provide recommendations for an effective, accurate, and practical software solution. This software solution allows dorsal fins to …


Our Places To Tell Stories: Making Connections With Our Audiences, Public Lands Institute Jan 2006

Our Places To Tell Stories: Making Connections With Our Audiences, Public Lands Institute

Our Places to Tell Stories

The idea for an annual Our Places Tell Stories conference was prompted by discussions that took place within a unique partnership of federal, state, university, and public organizations in southern Nevada. Members identified the need to share and learn from successful educational and interpretive strategies. Our increasingly urban surroundings and rapidly changing populations hinder personal connections between people and their natural environment. However, the right tools and techniques will help us inspire children and adults to understand, value, and take care of our shared natural places.

This first conference supports professionals in creating and evaluating effective educational programs and interpretive …

Red Rock Desert Learning Center Community Outreach Activities Plan, Red Rock Desert Learning Center

Oliver Ranch Project

The Red Rock Desert Learning Center is being designed to teach participants about the natural world through inquiry-based experiential and interdisciplinary methods in a residential outdoor setting in Red Rock Canyon National Conservation Area. The intent is for students, teachers, and researchers to gain an appreciation of desert ecosystems and to begin to apply and connect their knowledge to world ecological systems. The campus will incorporate many “green building” systems in its design and operation, and those systems will be an active part of the school’s curriculum.

Environmental Awareness Of Waterville Junior High School Students, Jenna Morrison Jan 2006

Environmental Awareness Of Waterville Junior High School Students, Jenna Morrison

Honors Theses

An environmental awareness survey was designed to assess the influences of gender and grade level on the relationships among outdoor experience, environmental knowledge, and environmental behavior at Waterville Junior High School, Waterville, ME. Environmental awareness indicates a fundamental understanding of the natural world, which is essential for developing future sustainable development. The foundation and acquisition of environmental knowledge of Waterville Junior High School students was determined using the multiple-choice survey. A total of 125 sixth graders and 136 eighth graders were surveyed. 61% of sixth graders and 73% of eighth graders indicated that their most common source of environmental information …


Salt Ingestion Caves, Charles A. Lundquist, William W. Varnedoe Jr. Jan 2006

Salt Ingestion Caves, Charles A. Lundquist, William W. Varnedoe Jr.

International Journal of Speleology

Large vertebrate herbivores, when they find a salt-bearing layer of rock, say in a cliff face, can produce sizable voids where, over generations, they have removed and consumed salty rock. The cavities formed by this natural animal process constitute a unique class of caves that can be called salt ingestion caves. Several examples of such caves are described in various publications. An example in Mississippi U.S.A., Rock House Cave, was visited by the authors in 2000. It seems to have been formed by deer or bison. Perhaps the most spectacular example is Kitum Cave in Kenya. This cave has been …


Relation Of Riparian Buffer Strips To In-Stream Habitat, Macroinvertebrates And Fish In A Small Iowa Stream, Jeremy P. Duehr, Michael J. Siepker, Clay L. Pierce, Thomas M. Isenhart Jan 2006

Relation Of Riparian Buffer Strips To In-Stream Habitat, Macroinvertebrates And Fish In A Small Iowa Stream, Jeremy P. Duehr, Michael J. Siepker, Clay L. Pierce, Thomas M. Isenhart

Journal of the Iowa Academy of Science: JIAS

Macroinvertebrate and fish habitat is often degraded as a result of agriculture. Riparian buffer strips are commonly used to counteract the negative effects of agriculture in headwater streams. We assessed the relation of multi-aged riparian buffer strips to in-stream habitat, macroinvertebrate and fish assemblages in an Iowa stream. In-stream habitat, macroinvertebrates, and fish were sampled from two buffered sites and two unbuffered sites, with the greatest substrate, water depth, and velocity heterogeneity occurring in buffered sites. The highest macroinvertebrate richness (11) as well as fish species richness (14), diversity (1.99) and IBI score (3 7) were found in the site …

Dendrochronological Analysis Of Productivity And Hydrology In Two Louisiana Swamps, John Blake Amos Jan 2006

Dendrochronological Analysis Of Productivity And Hydrology In Two Louisiana Swamps, John Blake Amos

LSU Master's Theses

Modified river flows and land subsidence have subjected many coastal swamp forests in the delta of the Mississippi River to greatly altered flooding, sediment, and nutrient regimes. These areas have become inundated to greater depth, duration, and frequency and either are connected to the river and receive drastically increased sediment and nutrients (riverine swamps) or have become disconnected from riverine flooding (stagnant swamps) and receive little or no sediment and nutrient input. To better understand how these changes are affecting ecosystems, dendrochronological techniques for baldcypress (Taxodium distichum L. Rich.) were used at three sites in each of two contrasting swamps …


Modeling The Effects Of Endocrine Disrupting Chemicals On Atlantic Croaker: Understanding Biomarkers And Predicting Population Responses, Cheryl Anne Murphy Jan 2006

Modeling The Effects Of Endocrine Disrupting Chemicals On Atlantic Croaker: Understanding Biomarkers And Predicting Population Responses, Cheryl Anne Murphy

LSU Doctoral Dissertations

A number of environmental stressors have been shown to interfere with reproductive and behavioral processes of fish by interfering with endocrine function. Most biomarkers of endocrine disturbance tend to be static measurements from dynamic systems making them difficult to evaluate within the context of an individual, or subtle effects that do not relate well to endpoints of ecological significance. I present an approach that uses a series of models, based on Atlantic croaker, to extrapolate laboratory results to indicators of individual and population health. First, I created a physiologically based model that simulates vitellogenesis in a female fish. The model …

Ecotoxicology And Environmental Education In The Development Of A Turtle Conservation Program In Southeastern Tennessee, Stefan L. Moss Dec 2005

Ecotoxicology And Environmental Education In The Development Of A Turtle Conservation Program In Southeastern Tennessee, Stefan L. Moss

Masters Theses and Doctoral Dissertations

In 1999, the Tennessee Aquarium initiated a long-term mark-recapture study to promote the conservation of freshwater turtles in the Tennessee River Gorge (TRG). The TRG consists of a 42-kilometer stretch of the Tennessee River surrounded by 27,000 acres (11,000 hectares) and is known as the "Grand Canyon of Tennessee." In 2002, the Aquarium established a partnership with The University of Tennessee at Chattanooga (UTC) and the Tennessee River Gorge Trust (TRGT) to expand the program. Since then, researchers at UTC have been conducting scientific research at the TRG each year in an effort to increase the amount of available information …
