Morphological And Molecular Systematics Of Resupinatus (Basidiomycota), 2015 The University of Western Ontario
Morphological And Molecular Systematics Of Resupinatus (Basidiomycota), Jennifer Mcdonald
Electronic Thesis and Dissertation Repository
Cyphelloid fungi are, compared to their gilled relatives, poorly studied and understood. Within the tribe Resupinateae (which includes the genera Resupinatus, Stigmatolemma, Aphyllotus and Stromatocyphella), little is known about the evolution of the cyphelloid fruit body form. How many times has this reduced morphology evolved within the group? Do all cyphelloid members that are currently treated in this group belong there? Are there other described species of cyphelloid fungi currently treated in other genera that belong within the Resupinateae? This study presents phylogenies of the cyphelloid and small lamellate members of the Resupinateae based on rDNA sequences to illustrate the ...
Forensic Autopsy. The Particularities Of Consent For Research, 2015 Carol Davila University of Medicine and Pharmacy
Forensic Autopsy. The Particularities Of Consent For Research, Sorin Hostiuc
Online Journal of Health Ethics
Forensic autopsy has as its main goal to find out the truth about the causes and circumstances of death, when there is a reasonable suspicion to be caused by a violent act. As the legal guardian cannot refuse a forensic autopsy, the forensic physician is free to perform any procedures considered to be necessary for finding out the truth (in order to answer to the objectives asked by the authority). However the use of biological samples or data in research is limited and needs an additional consent, from the legal guardian, which can lead to difficulties in the interpretation of ...
A Model Of How Different Biology Experts Explain Molecular And Cellular Mechanisms, 2015 Purdue University
A Model Of How Different Biology Experts Explain Molecular And Cellular Mechanisms, Caleb M. Trujillo, Trevor R. Anderson, Nancy J. Pelaez
Constructing explanations is an essential skill for all science learners. The goal of this project was to model the key components of expert explanation of molecular and cellular mechanisms. As such, we asked: What is an appropriate model of the components of explanation used by biology experts to explain molecular and cellular mechanisms? Do explanations made by experts from different biology subdisciplines at a university support the validity of this model? Guided by the modeling framework of R. S. Justi and J. K. Gilbert, the validity of an initial model was tested by asking seven biologists to explain a molecular ...
Illness And God's Will, 2015 Liberty University
Illness And God's Will, John Sherret
Senior Honors Theses
Originally, God never put sickness on people. After the fall, the early history of man as recorded in the Bible further demonstrates Him refraining to use sickness. However, once the law was instituted God began to use sickness as a punishment. In the Old Testament, sickness was always defined as a curse and never a blessing. It was used by God to curse people for disobeying the law. In the New Testament, God was seen healing the multitudes instead of cursing them. Through the atonement of Jesus, believers have been redeemed from the curse of the law (Galatians 3:13 ...
Habitat Features Predict The Distribution Of Recreational Shooters In The Morley Nelson Snake River Birds Of Prey National Conservation Area, Emily R. Sun, Benjamin P. Pauli, Zoe Tinkle, Romaric Mukuna, Daniel Wolfe, Jennifer S. Forbey, Julie Heath
College of Arts and Sciences Presentations
The Morley Nelson Snake River Birds of Prey National Conservation Area (NCA) is a popular destination of many Treasure Valley residents. There, recreationists participate in various pastimes such as target shooting, recreational shooting/hunting, and wildlife viewing. However, these activities have the potential to interfere with one another. Recreational shooting of Piute ground squirrels (Urocitellus mollis) could affect prey availability and scavenging opportunities for associated raptor species, most notably local golden eagle (Aquila chrysaetos) populations. To assess possible interactions among shooters, prey and raptors, the spatial density and habitat preference of human shooters must be determined. We hypothesized that higher ...
Concomitant Uptake Of Antimicrobials And Salmonella In Soil And Into Lettuce Following Wastewater Irrigation, 2015 University of Nebraska--Lincoln
Concomitant Uptake Of Antimicrobials And Salmonella In Soil And Into Lettuce Following Wastewater Irrigation, J. Brett Sallach, Yuping Zhang, Laurie Hodges, Daniel D. Snow, Xu Li, Shannon L. Bartelt-Hunt
Civil Engineering Faculty Publications
The use of wastewater for irrigation may introduce antimicrobials and human pathogens into the food supply through vegetative uptake. The objective of this study was to investigate the uptake of three antimicrobials and Salmonella in two lettuce cultivars. After repeated subirrigation with synthetic wastewater, lettuce leaves and soil were collected at three sequential harvests. The internalization frequency of Salmonella in lettuce was low. A soil horizon-influenced Salmonella concentration gradient was determined with concentrations in bottom soil 2 log CFU/g higher than in top soil. Lincomycin and sulfamethoxazole were recovered from lettuce leaves at concentrations as high as 822 ng ...
Using Network Models To Predict Steelhead Abundance, Middle Fork John Day, Or, 2015 Utah State University
Using Network Models To Predict Steelhead Abundance, Middle Fork John Day, Or, Monica R. Blanchard
All Graduate Theses and Dissertations
In the management of threatened and endangered species, informed population estimates are essential to gage whether or not recovery goals are being met. In the case of Pacific salmonids, this evaluation often involves sampling a small subset of the population and scaling up to estimate larger distinct populations segments. This is made complicated by the fact that fish populations are not evenly distributed along riverscapes but respond to physical and biological stream properties at varying spatial extents. We used rapid assessment survey methods and the River Styles classification to explore fish-habitat relationships at a continuous network scale. Semi-continuous surveys were ...
Does Personality Affect The Probability That Piute Ground Squrriels (Urocitellus Mollis) Will Be Shot By Recreational Hunters?, Daniel Wolfe, Zoe Tinkle, Benjamin P. Pauli, Emily Sun, Romaric Mukuna, Jennifer S. Forbey, Julie Heath
College of Arts and Sciences Presentations
Recreational shooting of Piute ground squirrels (Urocitellus mollis) in southern Idaho is an activity growing in popularity. One factor that may influence shooting success is the personality of individuals within a population. We hypothesized that bold individual ground squirrels would be more/less likely to be targeted by a hunter and would be more/less disturbed by gun fire. To test these hypotheses, we simulated recreational shooting to identify which personalities are more susceptible hunters and more responsive to gun fire. We preformed simulations in March of 2015 on a population of Piute ground squirrels with known personalities. Bold and ...
Songbirds And Their Sunglasses: A Study Demonstrating Avian Attraction To Highly Polarizing Horizontal Surfaces, Imaani J. Easthausen
Senior Projects Spring 2015
Research done in migratory birds over the last few decades has provided strong evidence suggesting that birds use cues from polarized light in the sky to guide orientation and navigation. If birds are able to detect skylight polarization patterns, then they could also be sensitive to polarized light in other non-migratory contexts – a possibility that has received minimal attention in the literature. Aquatic insects are known to depend on polarized light to identify water. While, historically, this has been a reliable cue, the rise and spread of urbanization has resulted in an increase in anthropogenic sources of polarized light – such ...
Proof-Of-Concept Of Environmental Dna Tools For Atlantic Sturgeon Management, 2015 Virginia Commonwealth University
Proof-Of-Concept Of Environmental Dna Tools For Atlantic Sturgeon Management, Jameson Hinkle
Theses and Dissertations
The Atlantic Sturgeon (Acipenser oxyrinchus oxyrinchus, Mitchell) is an anadromous species that spawns in tidal freshwater rivers from Canada to Florida. Overfishing, river sedimentation and alteration of the river bottom have decreased Atlantic Sturgeon populations, and NOAA lists the species as endangered. Ecologists sometimes find it difficult to locate individuals of a species that is rare, endangered or invasive. The need for methods less invasive that can create more resolution of cryptic species presence is necessary. Environmental DNA (eDNA) is a non-invasive means of detecting rare, endangered, or invasive species by isolating nuclear or mitochondrial DNA (mtDNA) from the ...
Dispersal: A Multidisciplinary Investigation Of Plant Life, 2015 Virginia Commonwealth University
Dispersal: A Multidisciplinary Investigation Of Plant Life, Alexandra E. Arzt
Theses and Dissertations
Using plants as a basis for exploring the interstices between the human and nonhuman, this thesis investigates ideas of awareness, intelligence, deep time, animism, and the fluctuating human perception of the agency of Nature. It outlines environmental art practices since the 1950s involving vegetal life. In addition, the paper provides a critical analysis of plant perception of Jakob von Uexküll’s work and theories of vital materialism and “critical plant studies” while noting recent studies in plant neurobiology. In my work, plants become active participants via their movement, seeding, and smell. This study takes the form of imitation, purposeful symbiosis ...
Quantitative Analysis And Imaging-Based Insights Into The Characteristics And Mechanisms Of Yeast Pattern Formation, 2014 The University of Texas Graduate School of Biomedical Sciences at Houston
Quantitative Analysis And Imaging-Based Insights Into The Characteristics And Mechanisms Of Yeast Pattern Formation, Lin Chen
UT GSBS Dissertations and Theses (Open Access)
Biofilm formation is a common lifestyle adapted by bacteria and fungi in response to various environmental stresses. Bacterial and fungal biofilms adhering to medical devices convey resistance to antibiotics or biocides, causing high rates of clinical infections. Microorganisms are protected from harsh environmental conditions by reduced stress penetration through the complex biofilm architecture with distinct patterns. Although the molecular regulations of surface patterning have been well characterized in bacteria, the mechanisms underlying the complex pattern formation in eukaryotic biofilms remain unclear.
This dissertation aims to investigate the salient features of robust colony expansion in yeast biofilms and the processes driving ...
Northern Bobwhite (Colinus Virginianus) Habitat Selection On A Reclaimed Surface Mine In Western Kentucky, 2014 University of Tennessee - Knoxville
Northern Bobwhite (Colinus Virginianus) Habitat Selection On A Reclaimed Surface Mine In Western Kentucky, Ashley Marie Unger
Reclaimed mines present an opportunity to provide large tracts of habitat for northern bobwhite (Colinus virginianus). Reclaimed mine sites are commonly planted to non–native species, including sericea lespedeza (Lespedeza cuneata) and tall fescue (Schedonorus phoenix), which can inhibit growth of more desirable plant species and limit favorable structure for bobwhite. Although bobwhite are found on reclaimed mine sites, there have been no studies documenting how bobwhites use various vegetation types common to reclaimed mine land. Habitat use studies can provide information on how bobwhite select vegetation types on these landscapes and help direct future management decisions. We trapped and ...
Tillage, Cover Crop And Nitrogen Fertilization Effects On Soil Microbial Carbon Dynamics Under Long-Term Cotton Production, 2014 University of Tennessee - Knoxville
Tillage, Cover Crop And Nitrogen Fertilization Effects On Soil Microbial Carbon Dynamics Under Long-Term Cotton Production, Molefi Jacob Mpheshea
Effective soil management requires a deeper understanding of how internal soil carbon (C) works. This is vital as cycling is tightly linked with nutrient cycling processes. This study evaluated the effect of agronomic practices including tillage (no-till and tilled), cover crops (no cover, hairy vetch - Vicia villosa L, and winter wheat - Triticum aestivum. L ) and different N fertilizer rates ( 0, 34 and 101 kg N per hectare ) on soil microbial C dynamics as measured by soil microbial biomass C (SMBC) along with soil microbial respiration over the 2013 cotton growing season at Jackson, West Tennessee. The study was set as ...

Un Cuento Satírico En Medio Del Debate Sobre El Darwinismo En México, 2014 University of South Florida
Un Cuento Satírico En Medio Del Debate Sobre El Darwinismo En México, Miguel A. Fernández Delgado Mafd
Alambique: Revista académica de ciencia ficción y fantasia / Jornal acadêmico de ficção científica e fantasía
Charles Darwin's theory of biological evolution of species was accepted or rejected by Mexican scientists, including Gabino Barreda, representative of Comte's philosophy. It was also included by Justo Sierra in a history book for the Escuela Nacional Preparatoria, a decision which raised a lot of criticism from conservative groups. It is also discussed the implications of social Darwinism in the early Twentieth Century Mexico. The document we offer is a satire published in those years, which resembles the tone of Swift's Gulliver Travels.
Aquaponics And Basil Plant Density, 2014 CSU-Sacramento
Aquaponics And Basil Plant Density, Danika L. Macmaster, Brook Murphy, Dudley Burton
STAR (STEM Teacher and Researcher) Program Posters
Aquaponics is the use of water from a fish tank to provide nutrients to plants in a soil-less environment. The rocks cultivate the bacteria that turns the ammonia into nitrates that the plants need, and the plant bed functions as a filter for the fish tank. In this study, with the guidance of Doctor Dudley Burton, Doctor Brook Murphy, we researched the optimal plant density for basil in an Aquaponics system. We attempted to control or measure all the other variables to consider, as to isolate the variable of distance between plants. The water flow was spread through the plant ...

The question of whether there is or was life on Mars has been one of the most pivotal since Schiaparellis’ telescopic observations of the red planet. With the advent of the space age, this question can be addressed directly by exploring the surface of Mars and by bringing samples to Earth for analysis. The latter, however, is not free of problems. Life can be found virtually everywhere on Earth. Hence the potential for contaminating the Mars samples and compromising their scientiﬁc integrity is not negligible. Conversely, if life is present in samples from Mars, this may represent a potential source ...
