Functional Influence Of 14-3-3 (Ywha) Proteins In Mammals, Elizabeth Barley, Santanu De Jan 2021

Functional Influence Of 14-3-3 (Ywha) Proteins In Mammals, Elizabeth Barley, Santanu De

Mako: NSU Undergraduate Student Journal

The 14-3-3 (YWHA) proteins are homologous, ubiquitous, and conserved in most organisms ranging from plants to animals and play important roles in regulating key cellular events such as cell signaling, development, apoptosis, etc. These proteins consist of seven isoforms in mammals, termed under Greek alphabetization: beta (β), gamma (γ), epsilon (ε), eta (η), tau/theta (τ), sigma (σ), and zeta (ζ). Each of these isoforms can interact with a plethora of binding partners and has been shown to serve a distinct role in molecular crosstalk, biological processes, and disease susceptibility. Protein 14-3-3 isoforms are scaffolding proteins capable of forming homodimers ...


Stygobitic Crustaceans In An Anchialine Cave With An Archeological Heritage At Vodeni Rat (Island Of Sveti Klement, Hvar, Croatia), Alessandro Montanari, Nicolas Cerveau, Barbara Fiasca, Jean-François Flot, Diana Galassi, Maurizio Mainiero, David Mcgee, Tadeusz Namiotko, Stefano Recanatini, Fabio Stoch Nov 2020

Stygobitic Crustaceans In An Anchialine Cave With An Archeological Heritage At Vodeni Rat (Island Of Sveti Klement, Hvar, Croatia), Alessandro Montanari, Nicolas Cerveau, Barbara Fiasca, Jean-François Flot, Diana Galassi, Maurizio Mainiero, David Mcgee, Tadeusz Namiotko, Stefano Recanatini, Fabio Stoch

International Journal of Speleology

A group of four amphoras found in the anchialine cave of Vodeni Rat in the Croatian island of Sveti Klement, on a rocky ledge at 24 m water depth, indicates that a freshwater source was exploited at the bottom of this karstic pit by islanders and/or passing-by sailors from the late Roman Republican Period to the Early Medieval Period. In other words, prior to the 4th–7th century CE, Vodeni Rat was not an anchialine cave but a Pleistocene karstic pit with a freshwater pool at the bottom. Seawater started to infiltrate this cavity via newly opened ...


Ecological Factors Influencing Wild Pig Damage To Planted Pine And Hardwood Seedlings, Micah P. Fern, James B. Armstrong, Rebecca J. Barlow, John S. Kush Sep 2020

Ecological Factors Influencing Wild Pig Damage To Planted Pine And Hardwood Seedlings, Micah P. Fern, James B. Armstrong, Rebecca J. Barlow, John S. Kush

Human–Wildlife Interactions

Expanding wild pig (Sus scrofa) populations across the southern United States has the potential to impact longleaf pine (Pinus palustris) restoration efforts. The depredation of planted pine seedlings is the most widespread and economically costly damage caused by wild pigs in forest plantations. A better understanding of the ecological factors affecting depredation rates will allow managers to implement best management practices to reduce seedling mortality from wild pigs at their most vulnerable stage of growth. From March 2016 to March 2017, we evaluated wild pig preferences for planted pine and hardwood species at a 34.4-ha cutover site and 4 ...


The Process And A Pitfall In Developing Biology And Chemistry Problems For Mathematics Courses, Mary Beisiegel, Lori Kayes, Devon Quick, Richard Nafshun, Michael Lopez, Steve Dobrioglo, Michael Dickens Jan 2020

The Process And A Pitfall In Developing Biology And Chemistry Problems For Mathematics Courses, Mary Beisiegel, Lori Kayes, Devon Quick, Richard Nafshun, Michael Lopez, Steve Dobrioglo, Michael Dickens

Journal of Mathematics and Science: Collaborative Explorations

In this paper, we describe our process for developing applied problems from biology and chemistry for use in a differential calculus course. We describe our conversations and curricular analyses that led us to change from our initial focus on college algebra to calculus. We provide results that allowed us to see the overlaps between biology and mathematics and chemistry and mathematics and led to a specific focus on problems related to rates of change. Finally, we investigate the problems that were developed by the partner disciplines for use on recitation activities in calculus and how those problems were modified by ...

Analysis Of The Genetic And Neurological Components Of Opioid Addiction, With Public Health Perspectives Of The Opioid Epidemic In The United States Of America, Janhavi A. Dubhashi Jan 2019

Analysis Of The Genetic And Neurological Components Of Opioid Addiction, With Public Health Perspectives Of The Opioid Epidemic In The United States Of America, Janhavi A. Dubhashi

DISCOVERY: Georgia State Honors College Undergraduate Research Journal

Opioid addiction has reached epidemic levels around the world, with over-prescription of opioid pain relievers being an often-cited reason for the epidemic in the USA. This project looks at opioid addiction from three perspectives: a review of literature dealing with the neural pathways involved in opioid use and addiction; the underlying genetic differences that can increase the risk of opioid use disorder; and an overview of the public health aspects of the epidemic. The paper will conclude with a review of current and new treatments based upon a growing neurobiological and molecular understanding of opioid use disorder.


Wildlife Damage To Crops Adjacent To A Protected Area In Southeastern Mexico: Farmers’ Perceptions Versus Actual Impact, Gabriel Can-Hernández, Claudia Villanueva-García, Elías José Gordillo-Chávez, Coral Jazvel Pacheco-Figueroa, Elizabeth Pérez-Netzahual, Rodrigo García-Morales Jan 2019

Wildlife Damage To Crops Adjacent To A Protected Area In Southeastern Mexico: Farmers’ Perceptions Versus Actual Impact, Gabriel Can-Hernández, Claudia Villanueva-García, Elías José Gordillo-Chávez, Coral Jazvel Pacheco-Figueroa, Elizabeth Pérez-Netzahual, Rodrigo García-Morales

Human–Wildlife Interactions

Human–wildlife conflicts occur when wildlife has an adverse effect on human activities (e.g., predation of livestock, crop raiding). These conflicts are increasing, particularly in areas surrounding natural protected areas, where villagers engage in subsistence agriculture. Crop damage may cause farmers to retaliate and harm wildlife species considered responsible for the damage. Among the factors that determine the intensity of the conflict are the frequency of the damage and the amount of biomass consumed relative to the perceptions, values, and cultural history of the farmers affected. To better understand the conflicts between farmers and wildlife, we compared farmer perceptions ...

The Influence Of Dose Of A Plant-Derived Volatile Cue On Arabidopsis Thaliana Resistance Against Insect Herbivores, Sarah Bissmeyer, Grace Freundlich, Christopher Frost Jun 2018

The Influence Of Dose Of A Plant-Derived Volatile Cue On Arabidopsis Thaliana Resistance Against Insect Herbivores, Sarah Bissmeyer, Grace Freundlich, Christopher Frost

Kentucky Journal of Undergraduate Scholarship

Green leaf volatiles (GLVs) are plant-derived volatile organic compounds (VOCs) known to affect plant-plant communication. Specifically, GLVs can facilitate “priming”, whereby plants initiate a faster and stronger defensive response to a subsequent stress. The stress-induced GLV cis-3-hexenyl acetate (z3HAC) is a known priming cue, yet whether the concentration of the z3HAC affects plant defenses is unknown. Here, we tested the hypothesis that z3HAC concentration of would influence Arabidopsis thaliana resistance against a specialist (Trichoplusia ni) and generalist (Spodoptera exigua) herbivore. Our z3HAC treatments ranged from 0-100 ng/hr, which spanned the range of recorded natural ...


Rat Infestation: An Analysis Of The Black Rat (Rattus Rattus) Outbreak Around Kamloops, Bc, Nick Fontaine Mar 2018

Rat Infestation: An Analysis Of The Black Rat (Rattus Rattus) Outbreak Around Kamloops, Bc, Nick Fontaine

Proceedings of the Annual Thompson Rivers University Undergraduate Research and Innovation Conference

Infestations of certain organisms occur when their living conditions are highly favourable. A species that is capable of quickly adjusting to a new environment, has a high reproductive output, no significant predators, and access to abundant resources will flourish. In particular, the Black Rat (Rattus rattus) population has increased rapidly within British Columbia over the last four years. The increase is currently understudied and greater research is needed on the specific distribution of rats and the influences on their population outbreak. Obtaining more knowledge about these factors could be the first step in controlling their population. Using information collected from ...


Therapy Dogs On Campus: An Exploration Of How Dog Therapy Services Affect Undergraduate Students’ Stress Levels, Tanna Lauriente, Drayden A.D. Kopp Mar 2018

Therapy Dogs On Campus: An Exploration Of How Dog Therapy Services Affect Undergraduate Students’ Stress Levels, Tanna Lauriente, Drayden A.D. Kopp

Proceedings of the Annual Thompson Rivers University Undergraduate Research and Innovation Conference

University can be stressful for many undergraduates. Fortunately, there are various stress reduction strategies, including weekly dog therapy sessions, offered at Thompson Rivers University. This study investigated the effects of dog therapy on students via a self-reported stress survey. Students in a control group (n= 98), who did not visit the therapy dogs, and a test group (n= 108), who did, provided data on their stress level and various other factors. Students in the test group reported their stress levels before and after participating in a dog therapy session by circling a number on our stress scale, determining their stress ...


The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne Jan 2018

The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne

Human–Wildlife Interactions

The federal government owns approximately 47% of all land in the western United States. In the state of Utah, about 64% of the land base is managed by the federal Bureau of Land Management (BLM) and the U.S. Forest Service (USFS). The government has historically issued permits to owners of private lands to allow the owners to graze their livestock on public lands. The permits (allotments) are generally of 10-year duration and allow for an annual season of use. In some cases, continued and repeated historical annual grazing practices may not be ideal for permit holders and their communities ...


A New Taxonomy Of Altruism In Terms Of Prosocial Behaviors, Kristin Kaiser Jun 2017

A New Taxonomy Of Altruism In Terms Of Prosocial Behaviors, Kristin Kaiser

Dialogue & Nexus

The definition of altruism has been studied, explained, and even confused by many scholars in various fields. The term itself has been inappropriately used to describe prosocial behaviors that do not fall within the definition of altruism. An evaluation of Grant Ramsey’s taxonomy of altruism, which includes biological altruism, psychological altruism, and helping altruism, proves that it is not adequate in categorizing organism’s behaviors. A new taxonomy, with the branches of kin selection, reciprocity, and aesthetic altruism, is presented and explained to clarify the definition of altruism and alleviate confusion about how to describe prosocial behaviors. Both naming ...


How Could Consciousness Emerge From Adaptive Functioning?, Max Velmans Sep 2016

How Could Consciousness Emerge From Adaptive Functioning?, Max Velmans

Animal Sentience

The sudden appearance of consciousness that Reber posits in creatures with flexible cell walls and motility rather than non-flexible cells walls and no motility involves an evolutionary discontinuity. This kind of “miracle” is required by all “discontinuity” theories of consciousness. To avoid miraculous emergence, one may need to consider continuity theories, which accept that different forms of consciousness and material functioning co-evolve but assume the existence of consciousness to be primal in the way that matter and energy are assumed to be primal in physics.


Seasonal Dynamics And Micro-Climatic Preference Of Two Alpine Endemic Hypogean Beetles, Stefano Mammola, Elena Piano, Pier Mauro Giachino, Marco Isaia Jun 2015

Seasonal Dynamics And Micro-Climatic Preference Of Two Alpine Endemic Hypogean Beetles, Stefano Mammola, Elena Piano, Pier Mauro Giachino, Marco Isaia

International Journal of Speleology

Hypogean beetles generally live in stable environments, characterized by constant temperature and high relative humidity. Changes in the underground microclimatic conditions generally induce local migrations of the beetles through the hypogean environment in search of suitable microhabitats. We studied the seasonal dynamics and the micro-climatic preference of two Alpine endemic hypogean beetles - Sphodropsis ghilianii (Coleoptera, Carabidae) and Dellabeffaella roccae (Coleoptera, Cholevidae) - in the hypogean complex of Pugnetto (Graian Alps, Italy). We surveyed the two species for one year, using baited pitfall traps and measuring temperature and humidity along the two main caves. We used logistic regression mixed models (GLMMs) to ...

Life-history aspects of Moxostoma cervinum(Blacktip Jumprock) were identified using specimens from recent collections and the Roanoke College Ichthyological Collection. The largest specimen examined was a female 161.27 mm SL and 66 months of age. Spawning appears to occur in May, with a mean of 2477.6 oocytes (SD = 2825.3) up to 1.54 mm diameter in gravid females. Sexual maturity appears to occur by 1-2 years of age in males and 2-3 years of age in females. Male to female ratio was not significantly different from 1:1. Chironomidae composed the bulk of the diet; while detritus ...


The Effect Of Applied Nitrogen And Subterranean Clover On The Growth Of Doublegee, D J. Gilbey Jan 1974

The Effect Of Applied Nitrogen And Subterranean Clover On The Growth Of Doublegee, D J. Gilbey

Journal of the Department of Agriculture, Western Australia, Series 4

Until 20 years ago doublegees in Western Australia were mainly confined to the red-brown earth soils of the wheatbelt.

Since then, they have spread to light loamy sand soils in the wheatbelt, many of which have carried subterranean clover from the mid-1940s onwards.

It has been widely presumed that the spread of doublegees on to the lighter sandy soils of W.A. can be associated with the establishment of subterranean clover on these soils.

This report summarises the results of a glasshouse experiment on the effect of clover and nitrogen on the growth of doublegee.
