Morpholino Gene Knockdown In Adult Fundulus Heteroclitus: Role Of Sgk1 In Seawater Acclimation, Emily G. Notch, Joseph R. Shaw, Bonita A. Coutermarsh, Marisa Dzioba, Bruce A. Stanton
Dartmouth Scholarship
The Atlantic killifish (Fundulus heteroclitus) is an environmental sentinel organism used extensively for studies on environmental toxicants and salt (NaCl) homeostasis. Previous research in our laboratory has shown that rapid acclimation of killifish to seawater is mediated by trafficking of CFTR chloride channels from intracellular vesicles to the plasma membrane in the opercular membrane within the first hour in seawater, which enhances chloride secretion into seawater, thereby contributing to salt homeostasis. Acute transition to seawater is also marked by an increase in both mRNA and protein levels of serum glucocorticoid kinase 1 (SGK1) within 15 minutes of transfer. …
Four Types Of Activities That Affect Animals: Implications For Animal Welfare Science And Animal Ethics Philosophy, D. Fraser, A. M. Macrae
Four Types Of Activities That Affect Animals: Implications For Animal Welfare Science And Animal Ethics Philosophy, D. Fraser, A. M. Macrae
Ethnozoology and Animal Welfare Collection
People affect animals through four broad types of activity: (1) people keep companion, farm, laboratory and captive wild animals, often while using them for some purpose; (2) people cause deliberate harm to animals through activities such as slaughter, pest control, hunting, and toxicology testing; (3) people cause direct but unintended harm to animals through crop production, transportation, night-time lighting, and many other human activities; and (4) people harm animals indirectly by disturbing ecological systems and the processes of nature, for example by destroying habitat, introducing foreign species, and causing pollution and climate change. Each type of activity affects vast numbers …

Ufd2a Isoforms With Vsp/P97 And Its Ibmpfd Mutants, Amanda St. Germain
Ufd2a Isoforms With Vsp/P97 And Its Ibmpfd Mutants, Amanda St. Germain
Honors Projects
Using the Yeast2Hybrid system, the binding affinities between Ufd2a variants and VCP/p97 mutants were analyzed. Several VCP/p97 mutants are associated with Inclusion body myositis in association of Paget's disease of the bone and fronto temperal dementia (IMBPFD). It was found that Ufd2a bound strongest to the VCP disease causing mutant A232E. It was also determined that the muscle specific isoform of Ufd2a, Ufd2a III, did not interact with VCP/p97.

Mind Perception: Real But Not Artificial Faces Sustain Neural Activity Beyond The N170/Vpp, Thalia Wheatley, Anna Weinberg, Christine Looser, Tim Moran, Greg Hajcak
Dartmouth Scholarship
Faces are visual objects that hold special significance as the icons of other minds. Previous researchers using event-related potentials (ERPs) have found that faces are uniquely associated with an increased N170/vertex positive potential (VPP) and a more sustained frontal positivity. Here, we examined the processing of faces as objects vs. faces as cues to minds by contrasting images of faces possessing minds (human faces), faces lacking minds (doll faces), and non-face objects (i.e., clocks). Although both doll and human faces were associated with an increased N170/VPP from 175–200 ms following stimulus onset, only human faces were associated with a sustained …

Effects Of 2, 4-D On Zea Maize Physiology, Caitlin Thompson, Lori Patrick, Acacia Osbourne, Katrina Brock
Effects Of 2, 4-D On Zea Maize Physiology, Caitlin Thompson, Lori Patrick, Acacia Osbourne, Katrina Brock
Featured Research
Growth rate, fluorescence and stomatal conductance, in zea was examined to determine the effects of artificial auxin, 2-4-d, on common crop plants. We measured florescence, growth rate, and stomatal conductance. Low concentrations of 2,4-D increased light-adapted fluorescence, anthocyanin levels and height of zea maize. A high concentration of 2,4-D increased anthocyanin levels, but also caused decreased fluorescence and height and spindliness to occur. It appears 2,4-D is only beneficial to monocot crop plants in low quantities. We cannot accurately comment on the accuracy of our data, however, due to several potential sources of error.

The unique semi-diurnal tide system of Southern California suspends beach wrack along the beaches for approximately six hour periods before being washed back into the ocean. It has been noted in prior research that beach wrack is an essential part of Southern California's costal ecology but not much research has been done to learn about the viability of beach wrack as it dehydrates on the beach. To better understand the viability of wrack as it travels through these hydration changes, this study tested the effect of dehydration and rehydration on the fronds of Macrocystis pyrifera as they have been partially …

The Effect Of Proximity To A Highway On The Health Of Malosma Laurina Leaves, Jessica Bermea, Haley Clayton, Jack Klobas
Featured Research
Due to an increase in air pollutants, heavy metal contaminates, and other adverse ecological conditions that plants near a road endure, it was hypothesized that plant species situated near a road would have a detectable decrease in photosynthetic performance when compared to plants away from the road. This investigation evaluated the in vivo photosynthetic status of two Malasma Laurina pairs with differing microhabitats, adjacent to the Pacific Coast Highway and 100 meters away from a Pacific Coast Highway. Maximum quantum yield and stomatal conductance measurements were recorded for each group. On average, the maximum quantum yield was greater on plants …
The Effect Of Hydration Status On Tensile Strength Of The Leaves Of Elymus Glaucus, Chelsie Corbett, Uri Hong, Scott Davis
The Effect Of Hydration Status On Tensile Strength Of The Leaves Of Elymus Glaucus, Chelsie Corbett, Uri Hong, Scott Davis
Featured Research
Tensile strength and water potential are both factors that are essential to the life and survival of a plant. Tensile strength is a measure of the amount of force that a plant can undergo before tissue damage and breakage occur. The primary objective of this study was to examine the correlation between tensile strength and leaf hydration status, or water potential. The water potential of leaves of a monocot grass native to North America, Elymus Glaucus, commonly known as blue wildrye, was measured using the Scholander-Hammel Pressure Chamber. The tensile strength of hydrated and of dehydrated leaves was measured …

The earthquake that struck Japan’s coast a month ago gained national attention for the damage caused by the tsunami that was caused by the earthquake. Japan’s coast is subject to multiple earthquakes each year with tremors and aftershocks following. The quakes are bound to have an effect on the growth and development of Camellia sinensis, the tea plant, which is one of the most important exports of Japan. Due to the time restraints of this project, C. sinensis were not tested, instead two week old Phaseolus vulgaris were used to show the effects of constant agitation which might mimic …
Effects Of Soil Moisture On Photosynthesis And Fluorescence In Heteromeles Arbutifolia, Ali Alyami, Colin Byrne, Katherine Currie
Effects Of Soil Moisture On Photosynthesis And Fluorescence In Heteromeles Arbutifolia, Ali Alyami, Colin Byrne, Katherine Currie
Featured Research
Some plants have evolved to increase their chances of survival by being drought-adapted. Among those plant species is Heteromeles arbutifolia, native to California. Logically, the fact that Heteromeles arbutifolia tolerates the low supply of water makes this plant more likely to be within environments where the level of sun exposure is high. Thus, we hypothesized that lowering soil moisture will cause an increase in xylem pressure, causing an increase in photo-protection and florescence, and a decrease in photosynthetic rate. This has not been tested before on a native chaparral plant such as Heteromeles arbutifolia. The experiment was held …

The Effect Of Nitrogen Soil Concentration On Leaf Fluorescence In Zea Mays, Ashton Garbutt, Daniel Rossie, Anup Solsi
Featured Research
Macronutrients in the soil are essential to the growth and development of a plant. One of the most important nutrients to a plants growth is nitrogen. Nitrogen has been directly correlated to photosynthetic output in various studies and this relationship is the subject of this experiment. Since nitrogen has an effect on photosynthetic rate, there should be a correlation between nitrogen and fluorescence – a form of energy dissipation. This study attempted to show that nitrogen concentration in the soil is inversely proportional to fluorescence of the plant because the more nitrogen in the soil, the more energy should be …
On The Theory Of Evolution Versus The Concept Of Evolution: Three Observations, Guillermo Paz-Y-Miño C, Avelina Espinosa
On The Theory Of Evolution Versus The Concept Of Evolution: Three Observations, Guillermo Paz-Y-Miño C, Avelina Espinosa
Arts & Sciences Faculty Publications
Here we address three misconceptions stated by Rice et al. in their observations of our article Paz-y-Miño and Espinosa (Evo Edu Outreach 2:655–675, 2009), published in this journal. The five authors titled their note “The Theory of Evolution is Not an Explanation for the Origin of Life.” First, we argue that it is fallacious to believe that because the formulation of the theory of evolution, as conceived in the 1800s, did not include an explanation for the origin of life, nor of the universe, the concept of evolution would not allow us to hypothesize the possible beginnings of …

In the spring of every year on Pepperdine University’s campus, patches of hills are covered with the South African native flower Dimorphotheca aurantiaca or more commonly known as the African Daisy. An observation of the opening and closing mechanism of the flower triggered an important question: does the flower change its shape based on temperature or the presence of light? At night, the African Daisy closes and then opens up again in the daytime. Because temperature has such strong effects on different species of ectodermic animals and temperature-sensitive plants, we hypothesized that the change in temperature initiates the flower’s morphological …
