The Use Of Argumentation In Socio-Scientific Issues: Enhancing Evolutionary Biology Instruction, Heath R. Marchand 2015 The College at Brockport

The Use Of Argumentation In Socio-Scientific Issues: Enhancing Evolutionary Biology Instruction, Heath R. Marchand

Education and Human Development Master's Theses

With the adoption of the Next Generation Science Standards (NGSS), further emphasis in science education is being placed on preparing students to become more informed voters regarding social, ethical, economic and political topics that affect contemporary society. Parallel to this shift is a stronger emphasis on integrating evolutionary theory as a unifying concept in the biological sciences. Given that evolution is one of the aforementioned topics commonly discussed and debated about in social and political arenas, ensuring that instruction provides students from all backgrounds a comprehensive understanding of its principals is becoming increasingly important in contemporary science education.

Riparian Restoration, Success Criteria, And Application To The Bart Sabrecat Creek Riparian Restoration Project In Fremont, California, Jody D. Fessler 2015 University of San Francisco

Riparian Restoration, Success Criteria, And Application To The Bart Sabrecat Creek Riparian Restoration Project In Fremont, California, Jody D. Fessler

Master's Projects

Riparian restoration is a complex, inter-disciplinary field that is open to interpretation by its practitioners. This research reviews some of the critical elements of riparian restoration, including the watershed, surrounding land use, adjacent habitat, and riparian buffers; special-status species, endangered species, and habitat type and structure; invasive species control; water quality and hydrology; and soil and soil microbial communities. Three methods of evaluating restoration projects are discussed, including the Society for Ecological Restoration International Primer, the California Department of Fish and Wildlife (CDFW) California Salmonid Stream Habitat Restoration Manual and CDFW permitting, and the California Rapid Assessment Method. Finally, the ...

Effects Of Ecologically Realistic Heating Profiles On Feeding In The Intertidal Hermit Crab, Pagurus Sameulis, Paige Davis 2015 Chapman University

Effects Of Ecologically Realistic Heating Profiles On Feeding In The Intertidal Hermit Crab, Pagurus Sameulis, Paige Davis

Student Research Day Abstracts and Posters

The intertidal zone is an ideal habitat to investigate effects of global warming because species living in it are very close to their physiological limits. Initial studies of invertebrate physiological responses to heat stress have employed relatively abrupt increases in temperature. My research investigates effects of ecologically more realistic temperature profiles on feeding in the intertidal hermit crab, Pagurus sameulis. Recent work in the Wright lab showed that feeding in this species is inhibited by an abrupt increase in temperature. Because temperature change in the natural environment of Pagurus is much more gradual, I hypothesize that such a gradual temperature ...


Biological Degradation Of Acetaldehyde In Southern California Coastal Waters, Mary Senstad, Sovanndara Hok, Ori Barashy, Catherine D. Clark, Warren J. De Bruyn 2015 Chapman University

Biological Degradation Of Acetaldehyde In Southern California Coastal Waters, Mary Senstad, Sovanndara Hok, Ori Barashy, Catherine D. Clark, Warren J. De Bruyn

Student Research Day Abstracts and Posters

Oxygenated hydrocarbons are ubiquitous in the atmosphere with levels ranging from low ppt (acetaldehyde) to low ppb (methanol). As an OH sink and an atmospheric HOx and ozone source, oxygenated hydrocarbons have a direct impact on the oxidative capacity of the atmosphere. The oceans are one of the largest sources of uncertainty in current atmospheric budget estimates of these species. A better understanding of the processes that produce and destroy these species in seawater would improve our understanding of the role of the oceans in cycling these species into or out of the atmosphere. We have measured the degradation rate ...


Evaluation Of Temperature Anomalies And Ocean Productivity During The 2004 Sumatra-Andaman Earthquake, Cora Byers, Brenna McNabb 2015 Chapman University

Evaluation Of Temperature Anomalies And Ocean Productivity During The 2004 Sumatra-Andaman Earthquake, Cora Byers, Brenna Mcnabb

Student Research Day Abstracts and Posters

The oceanic productivity of the Indian Ocean and temperature anomalies prior to the Sumatra-Andaman earthquake (MW =9.3) and tsunami (December 26th 2004) were studied. Data was obtained via NASA’s Giovanni program to determine the effect on phytoplankton (primary producers) and temperature changes over the region of the earthquake. Seasonal trends were visible in the concentrations of chlorophyll a, coccolithophores, cyanobacteria, chlorophytes, diatoms and absorption coefficient, in addition to storm trends.


Possible Precursor Events To Earthquakes And The Resulting Effects On Organic Material In The Surrounding Water Bodies, Kiyoko Nakatsui 2015 Chapman University

Possible Precursor Events To Earthquakes And The Resulting Effects On Organic Material In The Surrounding Water Bodies, Kiyoko Nakatsui

Student Research Day Abstracts and Posters

Being located on the “Ring of Fire” Japan experiences many seismic events. Adding to this, it is located at the convergence of four fault lines where seismic activity will be even more frequent and severe. Although small tremors occurring in an area are indicators of an earthquake to come it only gives minutes of warning. Scientists are now trying to see if latent heat and gas release from fault lines can indicate an earthquake to come with hours or even days of warning. MODIS aqua and terra data will be analyzed in order to see if such precursors can be ...


Puffs And Tufts: A Comparison Of Trichodesmium Colony Formations And Nutrient Availability Across The North Atlantic Ocean Using Remote Sensing Methods, Marc Rosenfield 2015 Chapman University

Puffs And Tufts: A Comparison Of Trichodesmium Colony Formations And Nutrient Availability Across The North Atlantic Ocean Using Remote Sensing Methods, Marc Rosenfield

Student Research Day Abstracts and Posters

Trichodesmium, a genus of diazotrophic bacteria, has the capability and the population to produce a large percentage of the total oceanic N2-fixation. Though their population is known to be heavily dependent on two of the ocean’s largest limiting factors, phosphorus and iron concentrations, it is unknown what affect these factors have on the population. In this study two of the largest colony formations of Trichodesmium in the North Atlantic, tufts and puffs, are compared nutrient quality with respect to time and geographical location. Though very little nutrient in situ data was collected from the cruise, remote sensing data collected ...


Effects Of El Niño On Ecological Growth Along Californian And Peruvian Coasts, Alexandra Sidun 2015 Chapman University

Effects Of El Niño On Ecological Growth Along Californian And Peruvian Coasts, Alexandra Sidun

Student Research Day Abstracts and Posters

This study examines the mechanisms of El Niño to further understand the ecological effects it may have along the Californian and Peruvian coasts. El Niño is the warm phase of the El Niño Southern Oscillation (ENSO). While it is a global phenomenon, these two locations were investigated for their nearly equal and opposite conditions during storm months. California, which is in an extreme state of drought, often receives heavy rainfall during El Niño and understanding its potential effects is crucial. El Niño causes upwellings along the CA coast and warm water from the region displaces the normally cool waters along ...


Assessing Water Quality In The Gulf Of Mexico Using Remote Sensing Data., Alliyah Thomas 2015 Chapman University

Assessing Water Quality In The Gulf Of Mexico Using Remote Sensing Data., Alliyah Thomas

Student Research Day Abstracts and Posters

Hypoxia, or oxygen depletion, is a process that occurs in conjunction with eutrophication. In hypoxic conditions the dissolved oxygen levels in the water column sink to unlivable conditions for the marine organisms causing them to flee or die. Despite efforts of improvement, the annual summer Gulf of Mexico dead zone continues to be a serious threat to aquatic ecosystems. The 2012 smaller than usual dead zone was a false indicator of future improvement. The 2012 dead zone decrease was connected to the drought and inability of large amounts of runoff to flow into the gulf. Water quality analysis was done ...


Effects Of Human Recreational Activity On The Tameness Of Common Loons (Gavia Immer) In Northern Wisconsin, Seth Yund 2015 Chapman University

Effects Of Human Recreational Activity On The Tameness Of Common Loons (Gavia Immer) In Northern Wisconsin, Seth Yund

Student Research Day Abstracts and Posters

The Common Loon (Gavia immer) is an aquatic diving bird that lives in freshwater habitats in Canada and the northern U.S.. Human activity on a loon’s resident lake may affect its fitness and behavior, yet few studies identify or quantify these effects. We modified existing techniques that measure escape distances in other species to measure tameness as the distance at which individual loons dove in response to human approach by canoe. Tameness was similar between pair members, suggesting that common lake conditions or the behavior of a mate might influence the behavior. Sex, size within sex, and human ...


Indigenous Engagement In Tropical River Research In Australia: The Track Program, Sue E. Jackson, Michael Douglas 2015 Australian Rivers Institute, Griffith University

Indigenous Engagement In Tropical River Research In Australia: The Track Program, Sue E. Jackson, Michael Douglas

The International Indigenous Policy Journal

The literature on scientific-Indigenous ecological knowledge collaborations rarely analyses programmatic efforts undertaken by multi-disciplinary research groups over very large geographic scales. The TRaCK (Tropical Rivers and Coastal Knowledge) research program was established to provide the science and knowledge needed by governments, industries, and communities to sustainably manage northern Australia’s rivers and estuaries. A number of policies and procedures were developed to ensure that the needs of Indigenous people of the multi-jurisdictional region were addressed and to enhance the benefits they might derive from participating in the research. An overarching Indigenous Engagement Strategy undergirded the program’s engagement activities, providing ...

Fishing For A Sustainable Future: Aquaponics As A Method Of Food Production, Richard Ramsundar 2015 Fordham University

Fishing For A Sustainable Future: Aquaponics As A Method Of Food Production, Richard Ramsundar

Student Theses 2015-Present

This thesis compares and explains the advantages aquaponics farming has over modern industrial intensive farming. Through a comparison natural capital usage, conservation, recycling and cost, the thesis advocates for the expansion of aquaponics usage in urban settings. The thesis also explains the history of intensive farming and aquaponics in America, the science of how aquaponics operates, the economic and environmental costs of modern intensive farming versus aquaponics farming, and the social implications of aquaponics. Lastly, I propose a policy that reallocates farm subsidies by modifying the Farm Bill. Then I propose policies that support creating a new standard of farm ...


Distributional Expansion Of The Hispid Cotton Rat (Sigmodon Hispidus) Into Dawson County, Nebraska, Jennifer D. Frisch, Keith Geluso, Joseph T. Springer 2015 University of Nebraska at Kearney

Distributional Expansion Of The Hispid Cotton Rat (Sigmodon Hispidus) Into Dawson County, Nebraska, Jennifer D. Frisch, Keith Geluso, Joseph T. Springer

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

In the last century, the Hispid Cotton Rat (Sigmodon hispidus) has moved northward in central parts of the United States, reaching Nebraska in the late 1950s. Recent surveys demonstrate Hispid Cotton Rats inhabit counties across southern parts of Nebraska south of the Platte River. Herein, we report on captures of S. hispidus from a new county (Dawson County), its seasonal occurrence at our study site, and the first known record of the Hispid Cotton Rat north of channels of the Platte River. Our captures represent one of the northern-most records in Nebraska.


Observations On The Life History Of The Bayou Killifish, Fundulus Pulvereus (Everman 1899) In Mississippi Tidal Marshes, Leah C. Gaines 2015 University of Southern Mississippi

Observations On The Life History Of The Bayou Killifish, Fundulus Pulvereus (Everman 1899) In Mississippi Tidal Marshes, Leah C. Gaines

Master's Theses

This study provides insight into the life history of the relatively unknown intertidal marsh fish Fundulus pulvereus (Everman), the bayou killifish. Monthly sampling for F. pulvereus took place in three different Mississippi tidal marshes over a period of 17 months (n=445). Observations on the diet, parasite fauna, and fecundity of the bayou killifish were documented on all specimens collected. Percent Occurrence and Percent Number coupled along with multivariate analyses indicated seasonal, site, and ontogenetic shifts in the diet of F. pulvereus. Dominant prey items consumed by F. pulvereus were copepods, mites, chironomids, and terrestrial and aquatic insects. The bayou ...


A Case For An Ecological Approach And Against Language Commodification In Elt, Vinicius O. Souza 2015 SIT Graduate Institute

A Case For An Ecological Approach And Against Language Commodification In Elt, Vinicius O. Souza

MA TESOL Collection

This paper aims to provide an alternative approach to the English language education practiced in many developing countries which can help reverse their current low-proficiency status, as revealed by standard international examinations such as the PISA scores and others. The author argues that this can be best accomplished by adopting an ecological approach to teaching which promotes language learning as emergent and socially situated phenomena, two concepts largely neglected by current teaching methods. In fact, many of these countries have long been dominated by an extremely commodified and cognitivist ELT market, where business interests have taken precedence over pedagogical considerations ...


Soil Preferences Of Nicrophorus Beetles And The Effects Of Compaction On Burying Behavior, Kelly A. Willemssens 2015 University of Nebraska-Lincoln

Soil Preferences Of Nicrophorus Beetles And The Effects Of Compaction On Burying Behavior, Kelly A. Willemssens

Dissertations & Theses in Natural Resources

The American burying beetle, Nicrophorus americanus Olivier was declared federally endangered in 1989 and many efforts to prevent this species from going extinct are ongoing. The Nicrophorus beetles bury small carcasses for reproductive purposes. They also reside in the soil during times of daily and seasonal inactivity. To better understand why N. americanus is in decline, the importance of soil texture, moisture, vegetation, gravel, the burial depth, and the effect of compaction on their burying behavior was examined.

All tested species preferred moist soils with N. orbicollis having a significant preference for wet (pN. marginatus had a significant preference for ...


Coupling Soil Oxygen And Greenhouse Gas Dynamics, Karla M. Jarecke 2015 University of Nebraska-Lincoln

Coupling Soil Oxygen And Greenhouse Gas Dynamics, Karla M. Jarecke

Dissertations & Theses in Natural Resources

Dynamic soil hydrology triggers important shifts in soil biogeochemical and physical processes that control greenhouse gas (GHG) emissions. Soil oxygen (O2), a direct control on biogenic GHG production (e.g. nitrous oxide-N2O, carbon dioxide-CO2 and methane-CH4), may serve as both an important proxy for determining sudden shifts in subsurface biogenic GHG production as well as the physical transport of soil GHG to the atmosphere. Recent technological advancements offer opportunities to link in-situ, near-continuous measurements of soil O2 concentration to soil biogeochemical processes and soil gas transport. Using high frequency data, this study asked: Do ...


Rareness Starts Early For Disturbance-Dependent Grassland Plant Species, Matthew Candeias 2015 SUNY Buffalo State

Rareness Starts Early For Disturbance-Dependent Grassland Plant Species, Matthew Candeias

Biology Theses

Ecological communities always contain a few common species and an abundance of rare species. Mechanisms determining commonness and rarity require experimental investigation. Given that most plant mortality occurs in seeds and seedlings, recruitment best predicts plant community assemblage and distributions. In northeastern North America, grassland plant species constitute a sizable portion of the native flora. Approximately 30% of western New York’s threatened and endangered flora are associated with grasslands, apparent leftovers from a post-glacial landscape. I investigated the mechanisms behind grassland species commonness and rarity by examining how habitat type, disturbance and biotic interactions limit seed recruitment for three ...
