Use Of Coastal Islands By Seabirds: A Tool To Guide Future Marine Protected Areas In California, Dana A. Page 2014 University of San Francisco

Use Of Coastal Islands By Seabirds: A Tool To Guide Future Marine Protected Areas In California, Dana A. Page

Master's Projects

Seabird breeding colonies on islands off the coast of California offer a unique tool to help guide marine spatial planning. The life histories of seabirds can be used to develop locations of ecological importance along the coast of California. Tracking methodologies and habitat modeling related to seabird habitat utilization can be used to inform management approaches which can aid in the expansion of marine protected areas (MPAs). Protecting ocean habitats will help mitigate impacts of climate change and ensure the ecosystem services provided by marine environments. Areas within the Monterey Bay National Marine Sanctuary were analyzed to locate candidate MPA ...


Water Water Everywhere: Analyzing Long Island's Water Issues And Finding Solutions For A Sustainable Future, Anthony T. Becker 2014 Fordham University

Water Water Everywhere: Analyzing Long Island's Water Issues And Finding Solutions For A Sustainable Future, Anthony T. Becker

2014 Student Theses

Over three million people call Long Island their home. With access to beautiful landscapes, world-renowned beaches, and proximity to New York City, it is no wonder that so many proudly call this geographic stretch of glacial till their home. However, throughout the years our actions do not necessarily reflect this affection we have to our home. Years of sprawl and human infestation across the island have resulted in widespread environmental degradation. Specifically, the water we drink and the beaches we enjoy have become endangered. I plan on studying the urban ecology of how intensified population growth led to the eutrophication ...


Response Of Large River Fishes To A Prolonged High Water Event In The Missouri River, Nebraska, Nicholas Paul Hogberg 2014 University of Nebraska - Lincoln

Response Of Large River Fishes To A Prolonged High Water Event In The Missouri River, Nebraska, Nicholas Paul Hogberg

Dissertations & Theses in Natural Resources

Regulation and modification of large rivers to accommodate human uses have been a root cause of freshwater biodiversity declines. The Missouri River is among the most drastically-altered large river systems in North America, with a series of mainstem impoundments in the upper watershed altering flow characteristics downstream, and channelization throughout the lower river homogenizing instream habitat and reducing off-channel habitat. Precipitation events during the winter and spring 2010-2011 caused flooding of the greatest magnitude and duration since reservoir completion. The large magnitude and long duration of this flood made it unlike any flood in recent history and provided a unique ...


The Detection Of Amazonian Manatees (Trichechus Inunguis) Using Side-Scan Sonar And The Effect Of Oil Activities On Their Habitats In Eastern Ecuador, Caitlin E. Brice 2014 Nova Southeastern University

The Detection Of Amazonian Manatees (Trichechus Inunguis) Using Side-Scan Sonar And The Effect Of Oil Activities On Their Habitats In Eastern Ecuador, Caitlin E. Brice

Theses and Dissertations

Substantial hunting pressure and habitat destruction caused by oil extraction has critically endangered the Amazonian manatee in Ecuador. The current population status is unknown because an effective method to observe them in the wild has yet to be developed. This study explored whether the Amazonian manatee persists or has been extirpated in the eastern Ecuadorian Amazon utilizing side-scan sonar to increase odds of detection. Spatial differences in probability of detection were quantified if manatees were observed. The level of chemical contamination was determined and compared spatially and temporally against historical data. Data were collected using opportunistic transect surveys and grab ...

Results Of 2013 Macroalgal Monitoring And Recommendations For Future Monitoring In Great Bay Estuary, New Hampshire, Elisabeth Cianciola, David Burdick 2014 University of New Hampshire

Results Of 2013 Macroalgal Monitoring And Recommendations For Future Monitoring In Great Bay Estuary, New Hampshire, Elisabeth Cianciola, David Burdick

PREP Publications

The recently designated nitrogen impairment and reports of elevated macroalgal growth in Great Bay Estuary indicate ecological imbalance. However, reversing the Estuary’s ecological decline will require commitment of considerable resources and is complicated by the variety of sources that deliver nitrogen to the Estuary and the intermittent nature of historic macroalgal monitoring. To advance our understanding of the macroalgal and nitrogen dynamics of the Estuary, data were collected via three approaches: 1) assessing plant cover and biomass along transects; 2) assessing plant cover at randomly selected points; and 3) comparing the nitrogen isotope ratios of macroalgae collected from different ...


Resident Benthic Fishes Of Artificial Reefs In The Mississippi Sound: Effects Of Habitat Relief And Subregion, Claire Louise Matten 2014 The University of Southern Mississippi

Resident Benthic Fishes Of Artificial Reefs In The Mississippi Sound: Effects Of Habitat Relief And Subregion, Claire Louise Matten

Master's Theses

One of the fundamental questions of artificial reef research concerns the capability of these manmade structures to promote secondary production. Many researchers have questioned whether artificial reefs increase the production of fish biomass, or simply aggregate existing fish biomass. Most previous research has focused on production of transient fish biomass, because of the high recreational and commercial value of these species. Establishing a link between transient fish production and artificial reef primary and secondary production has proved difficult. Therefore, the goal of this study was to examine the productivity of benthic fishes resident to artificial reefs in the Mississippi Sound ...


Taxonomy, Diversity, And Distribution Patterns Of Portunid Crab Megalopae In The Northern Gulf Of Mexico During Fall Of 2003, Carley Rain Knight 2014 The University of Southern Mississippi

Taxonomy, Diversity, And Distribution Patterns Of Portunid Crab Megalopae In The Northern Gulf Of Mexico During Fall Of 2003, Carley Rain Knight

Master's Theses

The field of zooplankton biology contributes to more accurate stock assessments as well as to a greater understanding of the marine food web. However, adequate information for the invertebrate component of zooplankton is lacking compared to the ichthyoplankton component. In this thesis, identification of Portunidae (Crustacea: Decapoda) megalopae collected during the fall of 2003 from a NOAA SEAMAP cruise revealed 7 species and 11 morphs with 90% of the total density comprised of Callinectes sapidus, Achelous gibbesii, Callinectes similis, Achelous spinicarpus, and Achelous sp.I. Keys and detailed descriptions are provided along with photographs and morphological drawings for each morph ...


Investigations Into Aldefluor As A Novel Method For Identifying Leukemia In Soft-Shell Clams, Katherine F. Norwood 2014 University of New Hampshire

Investigations Into Aldefluor As A Novel Method For Identifying Leukemia In Soft-Shell Clams, Katherine F. Norwood

Student Research Projects

The clam species Mya arenaria is a common model organism in leukemia research. The current method for classifying the degree of cancer progression is by examining cell morphology with light microscopy. This approach is highly qualitative, which makes differentiation of pre-leukemic and semi-leukemic individuals difficult. One quantitative approach that may differentiate individuals is based on levels of aldehyde dehydrogenase (ALDH) expression. The enzyme assay ALDEFLUOR® can actively measure ALDH expression in viable cells, but the effectiveness of certain protocol conditions is dependent upon the cell type.

The Effects Of Ocean Acidification And Eutrophication On The Growth, Lipid Composition And Toxicity Of The Marine Raphidophyte Heterosigma Akashiwo., Julia Rose Matheson 2014 Western University

The Effects Of Ocean Acidification And Eutrophication On The Growth, Lipid Composition And Toxicity Of The Marine Raphidophyte Heterosigma Akashiwo., Julia Rose Matheson

University of Western Ontario - Electronic Thesis and Dissertation Repository

Anthropogenic forcing, such as ocean acidification caused by rising carbon dioxide emissions, and eutrophication due to increased nutrient loadings in run-off, are causing major changes to the biogeochemistry of the oceans. As a consequence, coastal phytoplankton are susceptible to altered biogeochemical environments. This study examined the effect of a lower pH and increased levels of nutrients on the common coastal harmful alga, Heterosigma akashiwo. Growth rates, maximal cell yields, neutral lipid accumulation and toxicity of cells grown under various pH and nutrients regimes were measured. H. akashiwo growth was near maximal when grown at lower pH levels. There was a ...


Quantitative Depth Profile Of Prochlorococcus In The Pacific Ocean, Benjamin Carter Calfee 2014 University of Tennessee, Knoxville

Quantitative Depth Profile Of Prochlorococcus In The Pacific Ocean, Benjamin Carter Calfee

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Prochlorococcus is a genus of extremely abundant marine cyanobacterium. This microbe is responsible for the majority of the primary production within marine environments and is thought to be the single most abundant photosynthetic organism. In addition to accounting for such a large portion of the world’s photosynthetic activity, Prochlorococcus functions with a genome much smaller than most other primary producers. Thus due to its general abundance and overall importance in oceanic ecosystems, an experiment was prompted to derive the spatial and numerical separation of the members of this genus across the Pacific Ocean through the use of quantitative polymerase ...


A Female Audience Increases Frequency Of Showy Agonistic Displays In Male Siamese Fighting Fish, Raisa Lück 2014 University of Southern Maine

A Female Audience Increases Frequency Of Showy Agonistic Displays In Male Siamese Fighting Fish, Raisa Lück

Thinking Matters

The audience effect refers to a situation where individuals alter displays in the presence of bystanders. By changing display choice, displayers can optimize their effectiveness against both the opponent and audience. Many displays – territorial, aggressive, warning, and threatening – fall into the broad category of agonistic behavior. Male Siamese fighting fish (Betta splendens) are known for being territorial, and they use the same set of stereotypical displays repeatedly from one male to the next. I observed effects of a female audience on male Betta displays to determine if males use certain displays more frequently than others when a female is present ...
