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 …

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

Carsey Publications

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.

Final Environmental Data Report December 2012: Technical Support Document For The 2013 State Of Our Estuaries Report, Piscataqua Region Estuaries Partnership

PREP Reports & Publications

The Piscataqua Region Estuaries Partnership (PREP) is part of the U.S. Environmental Protection Agency’s National Estuary Program, which is a joint local/state/federal program established under the Clean Water Act with the goal of protecting and enhancing nationally significant estuarine resources. PREP is funded by the EPA and is administered by the University of New Hampshire.

The following sections contain the most recent data for the indicators currently tracked by PREP.

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

All Materials

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 …

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.

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 …

Evolution Of Vertebrate Gnrh Receptors From The Perspective Of A Basal Vertebrate, Stacia A. Sower, Wayne A. Decatur, Nerine T. Joseph, Mihael Freamat

New Hampshire Agricultural Experiment Station Publications

This minireview provides the current status on gonadotropin-releasing hormone receptors (GnRH-R) in vertebrates, from the perspective of a basal vertebrate, the sea lamprey, and provides an evolutionary scheme based on the recent advance of whole genome sequencing. In addition, we provide a perspective on the functional divergence and evolution of the receptors. In this review we use the phylogenetic classification of vertebrate GnRH receptors that groups them into three clusters: type I (mammalian and non-mammalian), type II, and type III GnRH receptors. New findings show that the sea lamprey has two type III-like GnRH receptors and an ancestral type GnRH …

Estrous Cycle-Dependent Changes Of Fas Expression In The Bovine Corpus Luteum: Influence Of Keratin 8/18 Intermediate Filaments And Cytokines, Alice Duncan, Jennifer Forcina, Alyssa Birt, David H. Townson

Molecular, Cellular & Biomedical Sciences

Background

Fas expression and Fas-induced apoptosis are mechanisms attributed to the selective destruction of cells of the corpus luteum (CL) during luteal regression. In certain cell-types, sensitivity to these death-inducing mechanisms is due to the loss or cleavage of keratin-containing intermediate filaments. Specifically, keratin 8/18 (K8/K18) filaments are hypothesized to influence cell death in part by regulating Fas expression at the cell surface.

Methods

Here, Fas expression on bovine luteal cells was quantified by flow cytometry during the early (Day 5, postovulation) and late stages (Days 16–18, postovulation) of CL function, and the relationship between Fas expression, K8/K18 filament expression …
