Gosnell Studies And Communicates Ecological Concerns, 2017 CUNY Bernard M Baruch College
Gosnell Studies And Communicates Ecological Concerns, Aldemaro Romero Jr.
Publications and Research
Scientists who study environmental problems know that the more you work in the field, the more insight you gain into how to solve problems. In other words, the more field experience you have, the deeper your understanding of nature.
One scientist who has had a lot of field experience is Dr. Stephen Gosnell, and his interest in the environment began when he was still a child. “I had interest really early. I grew up in rural South Carolina in a very small town called Landrum. I was outside on a regular basis, playing in the streams and creeks around me ...
Beyond The Obvious: Emerging Contaminants And Biogeochemistry As A Cause And Solution For Nitrogen Pollution, 2017 The Graduate Center, City University of New York
Beyond The Obvious: Emerging Contaminants And Biogeochemistry As A Cause And Solution For Nitrogen Pollution, Stephanie L. Devries
All Graduate Works by Year: Dissertations, Theses, and Capstone Projects
Following a comprehensive review of the occurrence and impacts of antibiotics and related pharmaceutical compounds on the terrestrial N-cycle, three experiments were performed to explore the topic of biogeochemistry as a source or a sink for N-pollution. The first of these experiments addresses the question of whether environmentally relevant concentrations of antibiotics (µg·kg-1) have a significant effect on denitrification or N2O production, a question that has not been well addressed in previous studies. Having determined that there is a significant shift, the second study aims to comprehensively follow changes to soil N pools and N2 ...
Human-Nonhuman Chimeras, Ontology, And Dignity: A Constructivist Approach To The Ethics Of Conducting Research On Cross-Species Hybrids, 2017 Western Michigan University
Human-Nonhuman Chimeras, Ontology, And Dignity: A Constructivist Approach To The Ethics Of Conducting Research On Cross-Species Hybrids, Jonathan M. Vajda
The Hilltop Review
Developments in biological technology in the last few decades highlight the surprising and ever-expanding practical benefits of stem cells. With this progress, the possibility of combining human and nonhuman organisms is a reality, with ethical boundaries that are not readily obvious. These inter-species hybrids are of a larger class of biological entities called “chimeras.” As the concept of a human-nonhuman creature is conjured in our minds, either incredulous wonder or grotesque horror is likely to follow. This paper seeks to mitigate those worries and demotivate reasonable concerns raised against chimera research, all the while pressing current ethical positions toward their ...
The Finney County, Kansas Community Assessment Process: Fact Book, 2017 Kansas State University
The Finney County, Kansas Community Assessment Process: Fact Book, Debra J. Bolton Phd, Shannon L. Dick M.S.
Dr. Debra Bolton
This multi-lingual/multi-cultural study was called, Community Assets Processt, by the groups that “commissioned” it: Finnup Foundation, Finney County K-State Research & Extension, Western Kansas Community Foundation, Finney County United Way, Finney County Health Department, United Methodist Community Health Center (UMMAM), Center for Children and Families, Garden City Recreation Commission, and the Garden City Cultural Relations Board, because we intend for this to be an ongoing discussion. An objective, for those promoting the study, was to connect foundation, state, and federal funding with activities or services that addressed the true needs of people living in Finney County. The group was looking for data that would offer insights on ways to address the needs of diverse audiences through human services agencies, County Extension, the schools, churches, and other entities working with community members of Finney County. Initially, an online survey was sent to directors of Finney County’s human service organization/agencies and schools. Directors were asked what sorts of data were required to help them quantify the needs of their client/customer bases. It was from those responses that the committee designed the survey instrument. The objective of the resulting survey instrument was to gather data that would: Identify resources available in Finney County (a Minority-majority county) Identify services needed in the community Capture information regarding well-being of people in Finney County Feature General Demographic (gender, age, race/ethnicity, education, household income) Length of years lived in Finney County Primary and secondary languages spoken at home (the survey was conducted in four (4) languages) Educational needs Health questions (insurance, health conditions, mental health, medical care, etc.) Social and health needs; and Questions to measure community engagement and social involvement Target individuals and groups of varying ages, socio-economic backgrounds, ethnic backgrounds, and religious affiliations. Target survey respondents 18 years or older Keep survey respondents’ identities confidential since the study was approved by Kansas State University’s Institutional Review Board for compliance in Research with Human Subjects. Data were gathered from about 1% of Finney County’s population through surveys and focus groups conducted in four languages better to understand the ...
Associated Dataset: Climate Change Impacts On Southern Ross Sea Phytoplankton Composition, Productivity And Export, 2017 Virginia Institute of Marine Science
Associated Dataset: Climate Change Impacts On Southern Ross Sea Phytoplankton Composition, Productivity And Export, Daniel E. Kaufman, Marjorie A.M. Friedrichs, Walker O. Smith Jr., Eileen E. Hofmann, Michael S. Dinniman, John C.P. Hemmings
This dataset includes data used in the publication Kaufman et al., 2017, JGR-Oceans in revision, which investigates how these climatic changes in the Ross Sea, Antarctica, may alter phytoplankton composition, primary productivity and export. A one-dimensional version of the Model of Ecosystem Dynamics, nutrient Utilisation, Sequestration and Acidification was adapted for use in the Ross Sea (MEDUSA-RS). Glider measurements were used to force MEDUSA-RS, which includes diatoms and both solitary and colonial forms of Phaeocystis antarctica. Model performance was evaluated with glider observations, and experiments were conducted using projections of physical drivers for mid- and late-21st century. Additional scenarios examined ...

Peatlands contain one-third of soil carbon (C), mostly buried in deep, saturated anoxic zones (catotelm). The response of catotelm C to climate forcing is uncertain, because prior experiments have focused on surface warming. We show that deep peat heating of a 2 m-thick peat column results in an exponential increase in CH4 emissions. However, this response is due solely to surface processes and not degradation of catotelm peat. Incubations show that only the top 20–30 cm of peat from experimental plots have higher CH4 production rates at elevated temperatures. Radiocarbon analyses demonstrate that CH4 and CO2 are produced primarily ...

This study examines ...
Intercanine Distance Used As A Measure To Rule Out Biters In Bite Mark Forensics, 2016 University of Tennessee, Knoxville
Intercanine Distance Used As A Measure To Rule Out Biters In Bite Mark Forensics, Alana Joy Scudiere Ohana
The science of identification by bite mark analysis has recently been called into serious question. (Reesu and Brown 2016) Human dentition is truly variable, but often not unique. When animal bites are considered, a proper ID of the perpetrator is nearly impossible. Primary distortion (when the bite is made) and secondary distortion (during decomposition or healing) both further disrupt landmarks that might be used for identification. (Sheasby and MacDonald 2001) Using only ink marks and intercanine distance on live subjects, this study attempts to determine maximum distortion possible for a variety of bite mark locations on skin. (Pretty and Sweet ...
Species Pluralism: Conceptual, Ontological, And Practical Dimensions, 2016 The University of Western Ontario
Species Pluralism: Conceptual, Ontological, And Practical Dimensions, Justin Bzovy
Electronic Thesis and Dissertation Repository
Species are central to biology, but there is currently no agreement on what the adequate species concept should be, and many have adopted a pluralist stance: different species concepts will be required for different purposes. This thesis is a multidimensional analysis of species pluralism. First I explicate how pluralism differs monism and relativism. I then consider the history of species pluralism. I argue that we must re-frame the species problem, and that re-evaluating Aristotle's role in the histories of systematics can shed light on pluralism. Next I consider different forms of pluralism: evolutionary and extra-evolutionary species pluralism, which differ ...
Evolutionary Genomics And Adaptive Evolution Of The Hedgehog Gene Family (Shh, Ihh And Dhh) In Vertebrates, 2016 Universidade do Porto - Portugal
Evolutionary Genomics And Adaptive Evolution Of The Hedgehog Gene Family (Shh, Ihh And Dhh) In Vertebrates, Joana Pereira, Warren E. Johnson, Stephen J. O'Brien, Erich D. Jarvis, Guojie Zhang, M. Thomas P. Gilbert, Vitor Vasconcelos, Agostinho Antunes
The Hedgehog (Hh) gene family codes for a class of secreted proteins composed of two active domains that act as signalling molecules during embryo development, namely for the development of the nervous and skeletal systems and the formation of the testis cord. While only one Hh gene is found typically in invertebrate genomes, most vertebrates species have three (Sonic hedgehog – Shh; Indian hedgehog – Ihh; and Desert hedgehog – Dhh), each with different expression patterns and functions, which likely helped promote the increasing complexity of vertebrates and their successful diversification. In this study, we used comparative genomic and adaptive evolutionary analyses to ...

Biomass And Biofuels In Maine: Estimating Supplies For Expanding The Forest Products Industry, 2016 University of Maine
Biomass And Biofuels In Maine: Estimating Supplies For Expanding The Forest Products Industry, Jonathan Rubin, Kate Dickerson, Jacob Kavkewitz
This paper estimates the renewable energy potential of Maine’s forest resources, and how much energy these resources could potentially provide the state. Using the most recent state-specific data available, and a methodology similar to the Billion Tons Report, we find that ethanol production from Maine’s forest residues could potentially provide 18% of Maine’s transportation (gasoline) fuels with a fermentation wood to ethanol process. Making Fischer-Tropsch diesel (F-T diesel) using forest residues can replace 39% of Maine’s petro-diesel consumption. Actual levels of biofuels that can be produced will depend on conversion factors and forestry residue removals that ...
A Quantitative Analysis Of Hugelkultur And Its Potential Application On Karst Rocky Desertified Areas In China, 2016 Western Kentucky University
A Quantitative Analysis Of Hugelkultur And Its Potential Application On Karst Rocky Desertified Areas In China, Megan Laffoon
Honors College Capstone Experience/Thesis Projects
A type of environmental degradation, karst rocky desertification (KRD) refers to areas where the soil loss exposes the bedrock and reduces the land’s ability to sustain life and is particularly widespread through the vast karst area of rural southwest China. Hugelkultur is a permaculture method that harnesses the wood decomposition process by burying logs beneath soil. We proposed that hugel beds will demonstrate a higher water holding capacity and enhance soil development, in a way that may show promise as a potential method to help alleviate problems of KRD. Soil samples were taken from hugel plots, non-hugel plots, and ...
Dietary Weight Loss Advice In Us Health Magazines And Its Relation To Ancestral Diet, 2016 Rockhurst University
Dietary Weight Loss Advice In Us Health Magazines And Its Relation To Ancestral Diet, Risa J. Stein, Marium A. Choudhry, Thomas J. Murray Jr.
Journal of Evolution and Health
As rates of overweight and obesity have risen in the US, the public has sought effective strategies for weight loss through dietary modification. A proliferation of processed foods and changing governmental nutrition guidelines have both impacted dietary intake patterns. While physicians are considered respectable sources of weight-loss information, increasingly the public has turned to the media, particularly magazines, for weight loss advice. This study investigated the dietary recommendations found in the five leading US health-related magazines and compared those recommendations to ancestral diets. With a couple notable exceptions, leading health magazines present consistent recommendations for dietary modifications to promote weight ...

Forecasting Climate Change Impacts On Plant Populations Over Large Spatial Extent, Andrew T. Tredennick, Mevin B. Hooten, Cameron L. Aldridge, Collin G. Homer, Andrew R. Kleinhesselink, Peter B. Adler
Wildland Resources Faculty Publications
Plant population models are powerful tools for predicting climate change impacts in one location, but are difficult to apply at landscape scales. We overcome this limitation by taking advantage of two recent advances: remotely sensed, species-specific estimates of plant cover and statistical models developed for spatiotemporal dynamics of animal populations. Using computationally efficient model reparameterizations, we fit a spatiotemporal population model to a 28-year time series of sagebrush (Artemisia spp.) percent cover over a 2.5 × 5 km landscape in southwestern Wyoming while formally accounting for spatial autocorrelation. We include interannual variation in precipitation and temperature as covariates in the ...
Comparative Genomics, Transcriptomics, And Physiology Distinguish Symbiotic From Free-Living Chlorella Strains, 2016 University of Nebraska-Lincoln
Comparative Genomics, Transcriptomics, And Physiology Distinguish Symbiotic From Free-Living Chlorella Strains, Cristian F. Quispe, Olivia Sonderman, Maya Khasin, Wayne R. Riekhof, James Van Etten, Kenneth Nickerson
Kenneth Nickerson Papers
Most animal–microbe symbiotic interactions must be advantageous to the host and provide nutritional benefits to the endosymbiont. When the host provides nutrients, it can gain the capacity to control the interaction, promote self-growth, and increase its fitness. Chlorella-like green algae engage in symbiotic relationships with certain protozoans, a partnership that significantly impacts the physiology of both organisms. Consequently, it is often challenging to grow axenic Chlorella cultures after isolation from the host because they are nutrient fastidious and often susceptible to virus infection. We hypothesize that the establishment of a symbiotic relationship resulted in natural selection for nutritional and ...
Botanical Therapeutics In The Modern World, 2016 CUNY Hostos Community College
Botanical Therapeutics In The Modern World, Vyacheslav Dushenkov, Brittany L. Graf, Mary Ann Lila
Publications and Research
Plants are the source of a broad spectrum of biologically active phytochemicals. For effective defense against pathogens and abiotic stress, plants have developed complicated chemical strategies with different mechanisms of action. By harnessing these phytochemicals, humans have used plants for medicinal purposes for over 30,000 years, and they remain a valuable source for the development of modern therapeutics. Plant-derived materials are utilized as pharmaceuticals, botanical drugs, dietary supplements (nutraceuticals), functional food ingredients, and cosmeceuticals. The Global Institute for Bioexploration (GIBEX), an international conglomerate of researchers, is involved in multiple botanical therapeutics discovery and development programs.
