Irondequoit Bay Monroe County, New York, Joseph C. Makarewicz, Matthew J. Nowak 2010 The College at Brockport

Irondequoit Bay Monroe County, New York, Joseph C. Makarewicz, Matthew J. Nowak

Technical Reports

Irondequoit Bay is approximately 4.2 miles long and 0.6 miles wide and is separated from Lake Ontario by a small barrier beach. Irondequoit Bay had been historically considered hypereutrophic when several sewage plants discharged directly into the bay; however, aggressive restoration by Monroe County has improved the eutrophic state of the bay. Restoration efforts included sealing the bottom sediments with alum, reducing both point and non-point sources of phosphorus, and the pumping of air into the hypolimnion to reduce phosphorus movement from the sediments into the water. Currently no direct sewage plant discharge is received, and phosphorus levels ...


Oak Orchard Creek Orleans County, New York, Joseph C. Makarewicz, Matthew J. Nowak 2010 The College at Brockport

Oak Orchard Creek Orleans County, New York, Joseph C. Makarewicz, Matthew J. Nowak

Technical Reports

Oak Orchard Creek is a major tributary of Lake Ontario, with a watershed straddling Orleans and Genesee counties. Surrounding land use is a mix of residential, small commercial businesses, and agriculture. The Elba and Oakfield sewage treatment plants are located along Oak Orchard Creek, as are three hydroelectric dams located in Oak Orchard, Glenwood, and Waterport (Zollweg et al. 2005). The New York State Department of Environmental Conservation lists fishing in Oak Orchard as threatened. There have been high measures of DDT, DDE, DDD, PAHs, and arsenic identified near Lyndonville, NY, at one of these sites (Makarewicz 2000). Nuisance algae ...


Twelvemile Creek Niagara County, New York, Joseph C. Makarewicz, Matthew J. Nowak 2010 The College at Brockport

Twelvemile Creek Niagara County, New York, Joseph C. Makarewicz, Matthew J. Nowak

Technical Reports

The east branch of Twelvemile Creek (69 mi2) flows through northern Niagara County to its mouth at Lake Ontario 12 miles east of the Niagara River, near the village of Wilson, New York. From fall through spring, good runs of steelhead and brown trout with the occasional Chinook and Coho salmon occur into the creek. Agriculture, especially row crop farming, is predominant within the watershed, though natural protected land is also plentiful. The Wilson-Tuscarora State Park provides a buffer between the creek and agriculture immediately around the mouth of the creek, while upstream farms directly line the creek. Nuisance ...

Status Of Wintering Grassland Birds In A Post-Hurricane, Salvage-Logged Forest, Matthew Edward Brooks 2010 Louisiana State University and Agricultural and Mechanical College

Status Of Wintering Grassland Birds In A Post-Hurricane, Salvage-Logged Forest, Matthew Edward Brooks

LSU Master's Theses

North American grassland birds have been declining at an alarming rate. Winter habitat for grassland species in the southeastern U.S. generally occurs within forests subject to management. I studied wintering grassland bird communities in De Soto National Forest in southern Mississippi. My objectives were to: 1) Assess bird communities and vegetation structure in upland forest stands that were salvage-logged following Hurricane Katrina, in stands managed for Red-cockaded Woodpeckers (Picoides borealis, RCW), and in stands containing bogs; and 2) Determine the extent of the association between vegetation and occurrence of the common wintering grassland birds. I conducted bird and vegetation ...


Implications Of Stunting On Morphology Of Freshwater Fishes, Christopher J. Chizinski, Kevin L. Pope, G.R. Wilde, R.E. Strauss 2010 Texas Tech University

Implications Of Stunting On Morphology Of Freshwater Fishes, Christopher J. Chizinski, Kevin L. Pope, G.R. Wilde, R.E. Strauss

Nebraska Cooperative Fish & Wildlife Research Unit -- Staff Publications

The purpose of this study was to assess morphological differences between stunted and non-stunted white perch Morone americana and green sunfish Lepomis cyanellus. Few female M. americana were captured; thus, morphological differences between adult males and juveniles were assessed for M. americana. Similarly, few immature (juvenile) L. cyanellus were captured for the stunted morphotype; thus, male and female morphological differences were assessed for L. cyanellus. Features of the head tended to be relatively larger in stunted fish of both species, whereas the mid-body tended to be relatively larger in non-stunted M. americana, but not in non-stunted L. cyanellus. Adult and ...

Bolivia's Coca Headache: The Agroyungas Program, Inflation, Campesinos, Coca And Capitalism In Bolivia, John D. Roberts 2010 University of Massachusetts Amherst

Bolivia's Coca Headache: The Agroyungas Program, Inflation, Campesinos, Coca And Capitalism In Bolivia, John D. Roberts

Masters Theses 1911 - February 2014

Bolivia in the 1980s was wracked by monetary inflation approaching levels of the German Weimar Republic. Immediately following this time of great financial crisis in Bolivia, the U.N. founded a project through the U.N.D.P. to encourage peasant farmers in Bolivia to switch from growing coca (the plant used manufacture cocaine) to growing other cash crops for market. This crop substitution and development program, called the Agroyungas Project, lasted from 1985 to 1991 and is the focus of this study. While many U.N. pundits and journalists considered the program’s initial small successes promising, it has ...


Behavior And Habitat Use Of Roseate Terns (Sterna Dougallii) Before And After Construction Of An Erosion Control Revetment, Corey Grinnell 2010 University of Massachusetts Amherst

Behavior And Habitat Use Of Roseate Terns (Sterna Dougallii) Before And After Construction Of An Erosion Control Revetment, Corey Grinnell

Masters Theses 1911 - February 2014

An erosion control revetment was constructed at the Falkner Island Unit of the Stewart B. McKinney National Wildlife Refuge, Connecticut during the winter of 2000–2001. At the time, Falkner Island was the fifth largest breeding colony site for the federally endangered Roseate Tern. This study measures and describes some baseline information regarding Roseate Tern nesting, behavior, and habitat use at Falkner Island during the three breeding seasons prior to revetment construction (1998–2000). This baseline information is then compared to similar information from the first breeding season following revetment construction (2001).

For Roseate Tern adults, this study examined changes ...


Sorption Of Bovine Serum Albumin On Nano And Bulk Oxide Particles, Lei Song 2010 University of Massachusetts Amherst

Sorption Of Bovine Serum Albumin On Nano And Bulk Oxide Particles, Lei Song

Masters Theses 1911 - February 2014

Manufactured oxide nanoparticles (NPs) have large production and widespread applications, which will inevitably enter the environment. NPs can interact with proteins in living beings due to the fact that NPs can transport into blood or across cell membranes into cells. Conformational change of protein molecules after sorption on oxide NPs has been reported. Therefore, it is important to understand the adsorption mechanism of protein onto oxide NPs surfaces. Although few works have reported protein adsorption behaviors, a general systematic comparison of the effects of particle size and surface groups on protein adsorption by widely studied NPs still needs to be ...

Social Learning For Resolving Community Conflict Over Land-Use Change To Plantation Forestry, Andrea Jane Leys 2010 Southern Cross University

Social Learning For Resolving Community Conflict Over Land-Use Change To Plantation Forestry, Andrea Jane Leys

Theses

This thesis examines social, economic, political and environmental challenges resulting from the conversion of agricultural land to hardwood forestry plantations for a sub-tropical region of Australia, notably the Upper Clarence catchment in north-eastern NSW. The conversion of agricultural land in the catchment to hardwood forestry plantations was an example of land-use change. This change has implications for natural resource management as a whole, as new operational and management practices impact differently on local ecosystems and communities. One of the aims of this study was to quantify these impacts and examine alternative management scenarios for increasing sustainability outcomes at the landscape ...


Analysis Of Eurycea Hybrid Zone In Eastern Missouri, Bonnie Jean Beasley 2010 Missouri University of Science and Technology

Analysis Of Eurycea Hybrid Zone In Eastern Missouri, Bonnie Jean Beasley

Masters Theses

"Evolutionary mechanisms are often difficult to observe in action because evolution generally works slowly over time. Hybrid zones provide a unique opportunity to observe many evolutionary processes, such as reinforcement, because of the rapid changes that tend to occur in these zones. Salamanders provide an ideal model for examining the rapid changes in populations that result from hybridization because many closely-related species lack reproductive barriers. In Missouri, a well-documented hybridization zone exists among the two subspecies Eurycea longicauda longicauda (long-tailed salamander) and E. L. melanopleura (dark-sided salamander). These salamanders inhabit caves, limestone creek beds, and abandoned mine shafts. A closely ...


Ecological And Evolutionary Connectivity Of Reef Corals In Subtropical Eastern Australia : Implications For The Persistence Of High-Latitude Coral Populations, Annika ME Noreen 2010 Southern Cross University

Ecological And Evolutionary Connectivity Of Reef Corals In Subtropical Eastern Australia : Implications For The Persistence Of High-Latitude Coral Populations, Annika Me Noreen

Theses

Coral reefs worldwide are threatened by a variety of pressures, and climate change models predict increasing levels of chronic stress as well as acute disturbances for most reefs. In addition to these global threats, populations on remote reefs are also predicted to be vulnerable due to their isolation from potential source reefs, usually low population size and associated increased extinction risk. Critical for the future of these reefs is dispersal and gene flow between populations (connectivity). This study investigated connectivity, population subdivision, and genetic diversity for three scleractinian reef coral species in discontinuous high-latitude nearshore coral communities and offshore reefs ...

The plan is required by the Oceans Act of 2008 to, among other things, be adaptive to evolving knowledge and understanding of the ocean environment. The plan’s Science Framework establishes a blueprint for future research and data acquisition and ensuring that the plan evolves and its management measures adapt to this new and enhanced information. As stated in Chapter 5 of the draft plan, an important part of the science framework is the development ...


Fire Disturbance, Forest Structure, And Stand Dynamics In Montane Forests Of The Southern Cascades, Thousand Lakes Wilderness, California, Usa, Matthew F. Bekker, Alan H. Taylor 2010 Brigham Young University

Fire Disturbance, Forest Structure, And Stand Dynamics In Montane Forests Of The Southern Cascades, Thousand Lakes Wilderness, California, Usa, Matthew F. Bekker, Alan H. Taylor

Wasatch Dendroclimatology Research

We examined tree diameter, age structure, and successional trends in 100 montane forest plots to identify the effects of variation in the return interval, severity, and extent of fires on forest structure and dynamics in the southern Cascade Range, California. We classified 100 forest plots into 8 groups based on stand structural characteristics. Median point fire return intervals were shortest in lower montane mixed conifer and Jeffrey pine–white fir stands (13-25 y) and upper montane red fir–white fir stands (14.5-19.5 y), intermediate in lodgepole pine stands (50-76.5 y), and longest in high-elevation red fir–mountain ...

The Index Of Biological Integrity And The Bootstrap: Can Random Sampling Error Affect Stream Impairment Decisions?, Christine L. Dolph, Aleksey Y. Sheshukov, Christopher J. Chizinski, Bruce Vondracek, Bruce N. Wilson

Nebraska Cooperative Fish & Wildlife Research Unit -- Staff Publications

Multimetric indices, such as the Index of Biological Integrity (IBI), are increasingly used bymanagement agencies to determine whether surface water quality is impaired. However, important questions about the variability of these indices have not been thoroughly addressed in the scientific literature. In this study, we used a bootstrap approach to quantify variability associated with fish IBIs developed for streams in two Minnesota river basins. We further placed this variability into a management context by comparing it to impairment thresholds currently used in water quality determinations for Minnesota streams. We found that 95% confidence intervals ranged as high as 40 points ...

Multi-Decadal Surface Temperature Trends In East Antarctica Inferred From Borehole Firn Temperature Measurements And Geophysical Inverse Methods, Atsuhiro Muto

Geography Graduate Theses & Dissertations

The climate trend of the Antarctic interior remains unclear relative to the rest of the globe because of a lack of long-term weather records. Recent studies by other authors utilizing sparse available records, satellite data, and models have estimated a significant warming trend in the near-surface air temperature in West Antarctica and weak and poorly constrained warming trend in East Antarctica for the past 50 years. In this dissertation, firn thermal profiling was used to detect multi-decadal surface temperature trends in the interior of East Antarctica where few previous records of any kind exist. The surface temperature inversion from firn ...
