Filtering Efficiency And Feeding Mechanisms Of Daphnia Pulex On Microcystis Aeruginosa And Nannochloropsis, Elizabeth Orlowicz

Honors Theses and Capstones

The filtering and feeding rate of Daphnia pulex from the Old Durham Reservoir, Durham, NH, were measured to determine the feeding efficiency on different concentrations of non-toxic Nannochloropsis (Class Eustigmatophyceae) and toxigenic cyanobacteria Microcystis aeruginosa. Direct observations of thoracic appendage beats and post-abdominal rejections were also measured at 5*10⁵ and 10⁶ cells mL^-1 concentrations of Nannochloropsis and M. aeruginosa to examine the feeding mechanisms of the D. pulex. In the presence of increasing Nannochloropsis concentrations, the filtering rates decreased and the feeding rates increased. When exposed to M. aeruginosa, both the filtering and feeding …

Restoring Oyster Reefs In Great Bay Estuary, Nh 2012 Annual Program Report, Ray Konisky, Raymond E. Grizzle, Krystin M. Ward, Kara Mcketon

PREP Reports & Publications

The eastern oyster (Crassostrea virginica) in New Hampshire’s Great Bay Estuary has declined in the past decades, with local populations reduced due primarily to disease, excessive siltation, and past over-harvest. The loss of filtering oysters results in diminished ecological benefits for water quality, nitrogen control, and other services that healthy oyster populations provide. In support of management objectives to restore oyster populations, The Nature Conservancy (TNC) and the University of New Hampshire (UNH) have combined for a fourth consecutive year of scaled-up methods to rebuild reefs and oyster populations. Since 2009, we have “planted” dried shell, primarily surf-clam …

Beliefs About Development Versus Environmental Tradeoffs In The Puget Sound Region, Thomas G. Safford, Matthew Cutler, Megan M. Henly, Karma Norman, Phillip Levin

The Carsey School of Public Policy at the Scholars' Repository

Using data from a phone survey of 1,980 Puget Sound residents conducted in 2012, this fact sheet outlines residents’ views about the importance of environmental protection as well as their opinions about energy development, protection of wild salmon, and land use regulation. Seventy-four percent of Puget Sound residents believe that protecting the environment should be a priority even if it means limiting economic growth. The majority of residents favor both increased use of renewable energy (82 percent) and protecting wild salmon (75 percent). Residents are more divided about curbing development, with those from rural areas being more apt to prioritize …

Public Perceptions Of Environmental Management In The Puget Sound Region, Thomas G. Safford, Matthew Cutler, Megan M. Henly, Karma Norman, Phillip Levin

The Carsey School of Public Policy at the Scholars' Repository

Using data from a phone survey of 1,980 Puget Sound residents conducted in 2012, this fact sheet describes public perceptions of different environmental interventions. Puget Sound residents widely support a range of proposed interventions designed to protect and restore the marine environment. These proposals include restricting boating and shipping activities to protect marine mammals such as killer whales and sea lions; more strongly enforcing existing environmental rules and regulations; spending government money to restore the environment for fish and wildlife; and providing tax credits to businesses that voluntarily reduce their environmental impact. Residents are divided about whether existing environmental regulations …

Urban-Rural Differences In Concern About The Environment And Jobs In The Puget Sound Region, Thomas G. Safford, Matthew Cutler, Megan M. Henly, Karma Norman, Phillip Levin

The Carsey School of Public Policy at the Scholars' Repository

Using data from a phone survey of 1,980 Puget Sound residents conducted in 2012, this fact sheet examines the severity of different environmental problems and compares the strength of concern about the lack of jobs and beliefs about the environment. Too few jobs and the loss of wildlife habitat were the two community issues most likely to be ranked as important problems among residents of Puget Sound. Environmental concern is higher among urban than rural residents, while those in rural areas are more likely than urbanites to believe the lack of jobs is a threat to their community.

Share Of Tax Filers Claiming Eitc Increases Across States And Place Types Between 2007 And 2010, Marybeth J. Mattingly, Elizabeth Kneebone

The Carsey School of Public Policy at the Scholars' Repository

In this brief, Authors Beth Mattingly and Elizabeth Kneebone use Internal Revenue Service tax filing data to show that the share of tax returns claiming the Earned Income Tax Credit (EITC) increased between 2007 and 2010, as did the size of the average credit claimed and the number of EITC filers benefitting from the refundable portion of the Child Tax Credit (the Additional Child Tax Credit, or ACTC). They report that one in five federal income tax filers claimed the EITC in tax year 2010, which represents a 4 percentage point increase since 2007, when just over one in six …

The 2010 Spring Drought Reduced Primary Productivity In Southwestern China, Li Zhang, Jingfeng Xiao, Jing Li, Kun Wang, Liping Lei, Huadong Guo

Earth Systems Research Center

Many parts of the world experience frequent and severe droughts. Summer drought can significantly reduce primary productivity and carbon sequestration capacity. The impacts of spring droughts, however, have received much less attention. A severe and sustained spring drought occurred in southwestern China in 2010. Here we examine the influence of this spring drought on the primary productivity of terrestrial ecosystems using data on climate, vegetation greenness and productivity. We first assess the spatial extent, duration and severity of the drought using precipitation data and the Palmer drought severity index. We then examine the impacts of the drought on terrestrial ecosystems …

Recessions Accelerate Trend Of Wives As Breadwinners, Kristin Smith

The Carsey School of Public Policy at the Scholars' Repository

This brief investigates the increased role employed wives played in family economic stability prior to, during, and in the two years after the Great Recession, and makes comparisons to the 1990-1991 and 2001 recessions. Author Kristin Smith reports that employed wives’ contribution to total family earnings jumped to 47 percent in 2009 from 45 percent in 2008—the largest single-year increase during the past twenty-three years—and has held steady at 47 percent in 2010 and 2011. Recessions substantially accelerate the trend of increased reliance on wives’ earnings. In all three recessions since 1988, annual increases in wives’ share of total family …

Lunar Radiation Environment And Space Weathering From The Cosmic Ray Telescope For The Effects Of Radiation (Crater), Nathan A. Schwadron, T. Baker, B. Blake, A. W. Case, J. F. Cooper, M. Golightly, Andrew P. Jordan, Colin J. Joyce, J. Kasper, K. Kozarev, J. Mislinski, J. Mazur, Harlan E. Spence

Physics & Astronomy

[1] The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) measures linear energy transfer by Galactic Cosmic Rays (GCRs) and Solar Energetic Particles (SEPs) on the Lunar Reconnaissance Orbiter (LRO) Mission in a circular, polar lunar orbit. GCR fluxes remain at the highest levels ever observed during the space age. One of the largest SEP events observed by CRaTER during the LRO mission occurred on June 7, 2011. We compare model predictions by the Earth-Moon-Mars Radiation Environment Module (EMMREM) for both dose rates from GCRs and SEPs during this event with results from CRaTER. We find agreement between these …

Scientific Basis For Safely Shutting In The Macondo Well After The April 20, 2010 Deepwater Horizon Blowout, Stephen H. Hickman, Paul A. Hsieh, Walter D. Mooney, Catherine B. Enomoto, Philip H. Nelson, Larry A. Mayer, Thomas C. Weber, Kathryn Moran, P. B. Flemings, Marcia Mcnutt

Center for Coastal and Ocean Mapping

As part of the government response to the Deepwater Horizon blowout, a Well Integrity Team evaluated the geologic hazards of shutting in the Macondo Well at the seafloor and determined the conditions under which it could safely be undertaken. Of particular concern was the possibility that, under the anticipated high shut-in pressures, oil could leak out of the well casing below the seafloor. Such a leak could lead to new geologic pathways for hydrocarbon release to the Gulf of Mexico. Evaluating this hazard required analyses of 2D and 3D seismic surveys, seafloor bathymetry, sediment properties, geophysical well logs, and drilling …

Physics & Astronomy

[1] Neutrons emitted from the Moon are produced by the impact of galactic cosmic rays (GCRs) within the regolith. GCRs are high-energy particles capable of smashing atomic nuclei in the lunar regolith and producing a shower of energetic protons, neutrons and other subatomic particles. Secondary particles that are ejected out of the regolith become “albedo” particles. The neutron albedo has been used to study the hydrogen content of the lunar regolith, which motivates our study of albedo protons. In principle, the albedo protons should vary as a function of the input GCR source and possibly as a result of surface …

Influence Of Temperature On The Physiology And Virulence Of The Insect Pathogen Serratia Sp. Strain Scbi, Lauren M. Petersen, Louis S. Tisa

Molecular, Cellular & Biomedical Sciences

The physiology of a newly recognized Serratia species, termed South African Caenorhabditis briggsae Isolate (SCBI), which is both a nematode mutualist and an insect pathogen, was investigated and compared to that of Serratia marcescens Db11, a broad-host-range pathogen. The two Serratia strains had comparable levels of virulence for Manduca sexta and similar cytotoxic activity patterns, but motility and lipase and hemolytic activities differed significantly between them.

In The Wake Of The Spill: Environmental Views Along The Gulf Coast, Lawrence C. Hamilton, Thomas G. Safford, Jessica D. Ulrich

Sociology

Abstract

Objectives

We analyze patterns in environmental views of Gulf Coast residents, in the wake of the 2010 oil spill. To what extent do spill-related and other environmental views vary with individual characteristics, personal experience with the spill, or characteristics of place?

Methods

About 2,000 residents of selected coastal regions in Louisiana and Florida were interviewed by telephone in late summer 2010.

Results

One-quarter of the respondents said that their environmental views had changed as a result of the spill. Despite reporting more change, more spill effects, and greater threats from climate-induced sea-level rise, Louisiana respondents were less likely to …

Southern Expansion Of The Brown Alga Colpomenia Peregrina Sauvageau (Scytosiphonales) In The Northwest Atlantic Ocean, Lindsay A. Green, Arthur C. Mathieson, Christopher D. Neefus, Hannah M. Traggis, Clinton J. Dawes

New Hampshire Agricultural Experiment Station Publications

Blackler first recorded Colpomenia peregrina in the Northwest Atlantic based on collections from Nova Scotia, Canada. Five decades later we found large quantities of C. peregrina in Maine, USA, even though it was absent during earlier floristic studies in this region. Thus, C. peregrina has undergone a rapid southern expansion along the Northwest Atlantic coast. While the causes of such an expansion are unknown, it could have a major effect on both shellfish cultivation and native seaweeds within New England because of competitive interactions and increased drag.

Coös County Youth And Out-Of-School Activities - Patterns Of Involvement And Barriers To Participation, Erin H. Sharp

The Carsey School of Public Policy at the Scholars' Repository

This fact sheet draws from surveys administered to a cohort of 416 participants in 7th grade in 2008, again when they were in 8th grade in 2009, and most recently as 10th graders in 2011 to look at patterns of participation in structured activities over time and whether male and female students differ in these patterns of participa¬tion. It also draws from questions added to the 2011 survey of 10th graders to examine Coös County youths’ perceptions about what kinds of barriers have kept them from getting more involved in structured out-of-school activities.
