The Default Effect: a closer look at reactance through environmental choice architectures	Jason Bixon	Choice architecture is a powerful influence on consumer decisions. One such influence, default architecture, results in disproportionately choosing options that are selected for someone, even when the default option is made salient and the choice is counterattitudinal. The present research tests the effects of default architecture on consumers' selection of renewable vs. nonrenewable energy for their home electricity. An experimental study tests whether transparency about the reasons for defaults reveals default effects choices.	Janet Swim	451
History of stress affects cell-mediated immunity	Kristen Maria Sprayberry	Eastern fence lizards (Sceloporus undulatus) are physiologically stressed by predatory venomous invasive fire ants (Solenopsis invicta). We examined how history of invasion (and associated stress) and acute stress treatment affected the cell-mediated immune response of lizards. Lizards from invaded sites had reduced immune response compared to those from uninvaded sites. Acute stress treatment affected lizards from invaded but not uninvaded sites, suggesting that evolutionary history of stress alters the immune response to short-term stress.	Tracy Langkilde	450
PTHrP may inhibit the growth-promoting effects of alcohol in the mammary gland	Jonathan Philippe Mercier and Cadie Dunlap	Alcohol increases estrogen signaling in mammary epithelial cells resulting in increased proliferation. We were interested in determining if PTHrP, a negative regulator of estrogen, could block the proliferative effects of alcohol. MCF-7 cells were treated with alcohol and/or PTHrP and proliferation was measured. Treatment of MCF-7 cells with alcohol caused an increase in proliferation whereas pretreatment with PTHrP inhibited these effects, suggesting that PTHrP may inhibit the growth-promoting effects of alcohol in the mammary gland.

The Effects of Competition on Defense of an Invasive Thistle Species, Carduus nutans	Rachel Lamb	Plants may trade off between growth and defense, especially when influenced by factors such as plant-plant interactions. We tested how thistle prickle count is affected by intraspecific competition (same species) and interspecific competition (different species). We manipulated growing conditions and counted prickles on three leaves per plant. Prickle count was significantly lower on leaves grown with interspecific and intraspecific competition than on controls. Our results suggest competition may have an effect on structural defense.

Mutagenic Studies of the Catalytic Core of RNase P	Timothy Andrew Bievenour	RNase P is a metalloenzyme which cleaves precursor tRNA. Two specific nucleotides, A90 and U93, are located in a strand of the P4 stem of the catalytic core of RNase P. This strand base-pairs with another RNA strand within the catalytic core, and the uracil and adenine nucleotides of interest are thought to 'stick out' to facilitate the binding of magnesium ions. We mutated these nucleotides to reveal their role in catalysis.	Dr. Andrey Krasilnikov	447
Privatization of Indecency Standards in the United States	Amanda Yaya	My research will examine the historical development of “indecency” in America as it was defined by corporate interests. Before World War II, tests for normalcy were created to segregate able-bodied workers from the disabled. Massumi and Žižek claim that neoliberal capitalism continues to promote regression towards the mean by absorbing dissident ideas and repackaging them for mass consumption. This is an interesting theory worth exploring within a subset of normalcy: cultural standards of decency.	Sean Weidman	446
Efficiency of Bard G2 Inferior Vena Cava (IVC) filter through tests with rigid spheres	Nicole Sylvia Price	Inferior vena cava (IVC) filters serve as a preventative tool to capture blood clots before they reach vital organs. This study involved testing the trapping efficiency of a Bard G2 IVC filter using rigid spheres under standard resting physiological conditions. Tracking of the spheres was done to create trajectory plots of the sphere to characterize the movement of the sphere through the IVC. These data will be used for comparison to similar computational models.	Keefe Manning	445
Effects of White Button Mushroom Feeding on Intestinal Gluconeogenesis and Glucose Homeostasis	Pratiti Roy	White button (WB) mushrooms have been reported to have health benefits, through poorly described mechanisms. Our data showed that WB feeding (1%) resulted in higher levels of cecal succinate and the succinate-producing bacteria Prevotella. Microbial succinate production induced expression of genes (G6Pase, Glut2, FFAR3, and SGLT3) important for intestinal gluconeogenesis (IGN) via the gut-brain neural circuit. Germ-free mice had no such WB mediated effect.	Margherita Cantorna	444
The Diversity of Transcriptionally Active Endogenous Retroviruses in Wyoming and Montana Mule Deer	Stephanie Nicole Williams	This project 1) identified transcriptionally active endogenous retroviruses within a population of Wyoming (WY) mule deer and 2) compared the diversity of transcriptional activity across two populations of mule deer that differ in their virus integration profile. This project was completed with Theodora Maravegias and Lei Yang under Dr. Mary L. Poss (maryposs@gmail.com). This project is intended to be submitted within the Department of Biology and presented from 5-7pm.	Dr. Mary Poss	443
Are Adults Aware of the Cues They Use to Label Someone as “Male” or “Female”?	Jane Hiu-Tung Chung	This study investigated adults' awareness of gender labeling processes by comparing the types of labeling strategies described by adults in two conditions. Adults who were asked candidly about gender labeling processes reported using biological cues and cultural cues, whereas adults who were shown a picture to label reported using cultural cues. This difference shows inconsistency between adults' awareness of labeling processes, prompting further exploration in the metacognition behind gender labeling by situation.	Lynn Liben	442
The Effects of Processing on the Inhibitory Efficacy of Cocoa Powder Against Phospholipase A2	Talia Nishay Seymore	Cocoa powder is rich in beneficial dietary phytochemicals. Research has shown that polyphenols in cocoa powder are able to inhibit the digestive enzymes; pancreatic lipase and amylase and pancreatic phospholipase A2. The alkalization and roasting that cocoa undergoes can affect the amount and composition of polyphenols in the resultant cocoa powder. The goal of this study was to determine the impact of alkalization and roasting on the PLA2 inhibitory effects of cocoa powders.	Joshua Lambert	441
NR5A2, What Do You Do?	Amelia E Rogus	Luteal NR5A2 abundance during early cyclicity, early pregnancy, and luteal regression was examined. NR5A2 mRNA decreased by 8hr after PGF2α injection. Protein tended to decrease by 0.5hr and decreased by 2hr after PGF2α. NR5A2 mRNA increased between D4 and D6 of the estrous cycle but protein abundance was unchanged. NR5A2 mRNA was lesser on D20 and D23 compared to D14 of pregnancy; no days differed from day 17. Protein abundance during early pregnancy was unchanged.	Joy Pate	440
Autonomous Vehicles in a Traffic Stream	Michael E Willis	Self-driving cars are very often in the news, and while many have speculated about their safety, there isn’t as much research about the actual efficiency of their impact on traffic. My plan for this project is to set up a scenario using Aimsun software where I can simulate the implementation of autonomous vehicles in a particular traffic stream, and add and change variables to see how much of an impact they make in different scenarios.	Dr. Vikash Gayah	439
Analysis of the Cause of Polar Mesosphere Winter Echoes	Nicholas Dimitrion and Alvaro Guerra	PMWEs are strong radar echoes that are recorded by VHF radars, when operating at 52 MHz and 224 MHz. They occur between 50-80 km in the polar regions of the atmosphere during the winter months. The PAWSS payload aims to answer the question- Are PMWEs the result of 3m electron density irregularities produced by neutral turbulence? To answer the question PAWSS, containing three different instruments, will fly from Andøya, Norway aboard the sounding rocket G-Chaser.	Timothy Wheeler	438
Quantification of Emboli Formation with Ultrasound Imaging	Cara Pearson	Blood flow will be mimicked using an in vitro flow loop and ultrasound, a diagnostic tool used for thrombi and emboli identification, records the formation of emboli in real-time in a bovine vessel. Afterwards, emboli development will be analyzed and quantified computationally. Little is understood about emboli development, therefore, techniques for studying real-time formation would be crucial for prevention.	Dr. Keefe Manning	437
Functional characterization of an ApiAP2 transcription factor in Plasmodium falciparum	Michelle Suhendra	My research project focuses on functionally characterizing an ApiAP2 transcription factor, known as PF13_0114 in Plasmodium falciparum, the malaria-causing parasite.	Manuel Llinas	436
Investigating the Determinants of the Reaction Outcomes of Fe-2OG-dependent Enzymes	Nhi Uyen Hoang	The objective of this study is to create engineered protein variants, in order to determine how the reaction outcomes in Fe-2OG-dependent enzymes are decided. One such enzyme, hyoscyamine-6β-hydroxylase, possess both hydroxylase and epoxidase functions. Depending on the variant’s properties, the outcome is either an increased hydroxy product or a secondary dihydroxy product. Screening the products is done two ways: whole-cell reactions to determine initial hits and purified enzyme reactions to verify their activity.	Ben Allen	435
Social Media as a Tool for Increasing the Reach of Behavioral Medicine Research	Nicole Elizabeth L'hommedieu	It is unclear whether social media attention increases the reach of research in behavioral medicine. This study examined 630 articles published in the Annals of Behavioral Medicine and Translational Behavioral Medicine from 2012-2017. The association between social media exposure and citation counts was low (r = 0.102, p < .05). Future work should explore whether specific social media forums are more effective than others for increasing the reach of scientific findings in behavioral medicine.	David Conroy	434
Design Opportunities in Deliberate Parenting Practices for Child Development	Olivia Kathleen Richards	There is a lack of understanding to best design technology to meet the needs of the parent-child relationship in engaging educational experiences toward skill and habit development. We began to address this research problem by conducting an interview study to gain insights into learning within the parent-child relationship. We identified deliberate parenting practices that highlight the untapped design opportunities to support the health, well-being and developmental concerns of both parents and their children simultaneously.	Meg Small	433
Handwritten Digit Multi-class Classification using SVM and LDA	Zhenyuan Yuan	This project presents investigation and results of multi-class classification using Linear Discriminant Analysis (LDA) and Support Vector Machines (SVM). Furthermore, by using different derivatives of LDA and SVM and different classification approaches, we obtain confusion matrices that describe the performances of each technique. Finally, a table summarizing the classification accuracy of each technique shows that SVM with Gaussian kernel, after PCA projection, using OVA classification method, achieves the highest classification accuracy.	Bharath Sriperumbudur	432
Complexity Measures Between Data Compression and Diophantine Approximation	Sean Thomas Cotner	We study abstract complexity measures that relate both to theoretical data compression and Diophantine approximation. We extract a group of axioms that aim to capture the core aspects of both. We illustrate this by numerical examples and theoretical properties, notably the analysis of the gzip compression algorithm and Liouville's theorem in Diophantine approximation.	Jan Reimann	431
Relationship of Platelet Adhesion with Surface Topography in the Penn State PVAD	Cecilia Richardsen	The Penn State pediatric ventricular assist device (PVAD) was designed to meet the need for a pediatric bridge-to-transplant device. While animal studies are encouraging, thrombus formation has been observed and patterns of platelet deposition are further explored. After PVAD ovine studies, blood sacs are evaluated using immunofluorescence and confocal microscopy, environmental scanning electron microscopy (ESEM), and optical profilometry (OP). Data from confocal, ESEM, and OP were correlated to find that surface topography can promote deposition.	Keefe Manning	430
Fire blight: amylovoran production and Erwinia amylovora virulence	Susie Liu	Fire blight is a contagious disease affecting apples and pears caused by the bacterium Erwinia amylovora. For bacteria to cause disease, they must produce amylovoran, a protective exopolysaccharide secreted by the bacteria to its environment. We are isolating mutant strains of E. amylovora that have altered amylovoran levels to discover novel genes that may be involved in amylovoran production. Preliminary results show a correlation between bacterial amylovoran production and disease in immature apples.	Timothy McNellis	429
Determining the Interactions between V. fischeri strains with Type VI secretion in vitro.	Austin Wittmer	Some bacteria possess a type VI secretion system (T6SS), a weapon that enables a bacterium to kill surrounding cells. This study investigates the extent to which Vibrio fischeri strains with a T6SS eliminate other nearby strains that also have a T6SS. Based on the data, multiple strains of V. fischeri with T6SS can co-exist within the same space; however, it is inconclusive if said strains can kill one another.	Tim Miyashiro	428
The Relationship between Sexual Attitudes and the HEXACO	Alyssa Rivera	The goal of my study is to determine the relationship between four multidimensional sexual attitudes and a more recently developed personality model called the HEXACO (Ashton & Lee, 2009). Past research has not found connections between personality and multidimensional attitudes of sexuality. These associations will determine how personality contributes to people’s perceptions of sexuality.	Michelle Yarwood	427
Hydrogen Sulfide Detection in Incubators	Christina Maria Debarberie	The average successful hatch rate of eggs in an in-home incubator is 70%. The eggs that fail to hatch pose a threat to the whole clutch due to hydrogen sulfide build up. Vigilant inspection for failed eggs is a time-consuming task that must be done throughout the incubation period. Using an embedded control system with a gas sensor to monitor the air inside the incubator and alert the user will solve that problem.	Sally Richmond	426
Eastern European Family Policy's Effect on Fertility and Women's Economic Status	Isabella Frances Teti	In this study I analyze the effects of pronatalist family policy on fertility and women’s economic status. I do this by analyzing five types of family policy and their impacts in Eastern European countries. My results confirm previous research which associates increased financial support for parents with increased fertility rates. It also suggests a more equitable division of family benefits, instead of unilateral support for mothers, would be the most beneficial for women economically.	Lee Ann Banaszak	425
Effect of Chronic Stress on SST+ GABAergic Interneurons	Shreya Bhatt	Stress increases the risk of Major Depressive Disorder. We used a mouse model in which SST+ cells were rendered hyperactive (SSTCre:γ2f/f mice), causing the mice to display an antidepressant phenotype, to study how activity of SST+ cells affects chronic stress-induced depressive behaviors. We quantified SST+ cells, which in control mice have been shown to be reduced by stress. We predict that SSTCre:γ2f/f mice are resilient to chronic stress-induced depressive behaviors and loss of SST+ cells.	Bernhard Luscher	424
The Effect of Time and Other Factors on Adolescent Responsibility	Nicholas Banerjee	The aim of the study was to answer three research questions: Is Socioeconomic status (SES) associated with adolescents’ responsibility across three waves of data? How does responsibility change across adolescence? The sample was 135 adolescents from Washington, DC metro area diverse in gender and race/ethnicity. SES was negatively associated with responsibility. Results from Repeated Measures ANOVA showed that responsibility as reported by parents, but not as reported by child, increased over time.	Emily Waterman	423
Identification of Activated Platelets in Bovine Blood Using P-Selectin Targeted Antibodies and Flow Cytometry	Catherine Eileen Blankemeyer	The implantation of cardiovascular technologies often leads to an increase in platelet activation as a result of non-biological geometries and high shear stresses, which can lead to thrombosis and clotting. Platelet activation levels can be quantified using flow cytometry by staining activated platelets with fluorophore-conjugated P-Selectin protein specific antibodies. This characterization of platelet activation is crucial in experimentally verifying predictions of platelet agitation that are made using computational fluid dynamics models of cardiovascular devices.	Keefe Manning	422
The Effects of Iron on Mood, Stress, and Quality of Life in Women of Reproductive Age	Emily Rebekah Seiger	The role that iron plays in affective outcomes is not well studied in women of reproductive age. The hypothesis is that iron supplementation will improve overall mood and quality of life and decrease feelings of stress compared to placebo. Participants recruited from Penn State were categorized as iron depleted or sufficient. Iron treatment improved feelings of Physical and Social Functioning and decreased feelings of Bodily Pain, Stress, Tension, Anger, Depression, Confusion and Total Mood Disturbance.	Laura Murray-Kolb	421
Sensorimotor speech control in young adults with ADHD	Crystal Dahm	The purpose of this research was to observe differences in sensorimotor speech control in participants with and without ADHD (n=49). Speech samples and quantitative somatosensory assessments were collected along with diagnostic interviews. Participants with ADHD demonstrated a faster speech rate than controls when recounting a story (p= .017) A negative correlational relationship was identified between spoken syllables per second and diagnostic assessments of ADHD. Further data analysis will be completed at the time of presentation.	Kristina Neely	420
New Antibiotic Development for Antibiotic Resistant Shigella flexneri	Josephine Beck	Antibiotic resistance is a current problem throughout the world, making bacterial infections more difficult to treat. Previously, a screen of 13,000 compounds was performed to test for potential antibiotics. Of those, two of the compounds were chosen for further testing. A minimum inhibitory assay, or MIC, will be performed using gram-negative bacteria, such as M. tuberculosis and S. flexneri. The MIC will determine the potential use of the compounds as an antibiotic against these bacteria.	Dr. Kenneth Keiler	419
War and Conflict in Regime Transitioning States	Timofey Velenchuk	The relationship between regime change and conflict is examined in the pre and post-Cold War period under the Eastern European and former Soviet Union states, the states which were directly impacted and related to the set-up of the world powers system during both periods.	Douglas Lemke	418
Study of Key Noise Characteristics for a Personal Flight Vehicle	Joseph Peter Calibeo	In order to evaluate noise, single and coaxial rotor configurations were created with a variety of parameters such as number of blades, lift coefficient, blade length, and tip speed. Acoustic pressure and noise for each rotor configuration were then calculated using the noise prediction code PSU-WOPWOP. The results of this parametric noise study were used to make a first-order estimate of the impact these design factors have on quiet flight for the proposed vehicles.	Kenneth Brentner	417
Coffe and Deforestation in Brazil	Mindy R Beam	Deforestation is directly influenced by the demand of coffee in the world. As the demand rises, the rate of deforestation in Brazil also rises. Since Brazil is one of the major landholders of the Amazon rainforest, the deforestation of their land impacts the global environment. By looking at the social, economic, and environmental impacts that coffee has on deforestation, a solution to produce a high yielding, environmental friendly product can be made.	Noel Hasaby	416
Development of an Acute Ischemic Stroke Hemodynamic Flow Model	Maximillian Moran and Thomas Donnelly	According to the CDC, approximately 122,000 Americans die each year due from lodged thromboemboli that are unable to be cleared following acute ischemic stroke. Despite this, there is a lack of research on what thromboemboli properties affect the success of re-canalization and patient outcomes. An ex vivo circulatory loop, incorporating an excised bovine artery and a programmable centrifugal pump, will be developed to simulate physiological cerebral flow conditions and investigate thromboemboli lodging and adhesion.	Keefe Manning	415
Surface Characterization of Implantable Long-Term Use Fontan Pump Materials	Clare Moire Mchugh	The goal of this project is to aid in the development of an implantable pump for patients with a failing Fontan circulation. These patients are increasingly surviving to adulthood and therefore require sustained support. Many blood contacting components of this pump are manufactured from poly-ether-ether-ketone (PEEK), for which biocompatibility has not been thoroughly characterized. This study will analyze surface characteristics of PEEK and compare them to previously characterized pump materials to analyze thrombosis potential.	Dr. Keefe Manning	414
Parent-Child Relationship During the College Planning Process	Kelly Vanden	Parent involvement in students’ college planning is crucial to their academic careers. My study explores students’ messages to their parents during this process. Juniors at two high schools responded to the question, “If you could tell your parents one thing as you begin the college planning process, what would it be?” We coded for content in the responses such as warmth, control, and anxiety. This study will improve college counseling programs for students and parents.	Meg Small	413
The Interrelationships Between Sleep, Physical Activity, Psychological Well-Being, and Gestational Weight Gain in Overweight and Obese Pregnant Women	Tara Rogers	Researchers examined associations between sleep, physical activity (PA), psychological health, and gestational weight gain (GWG) in 20 overweight/obese pregnant women participating in a 6-week weight-control intervention. Findings: sleep time was positively associated with PA and stress and negatively associated with depression; nap time was positively associated with psychological health. Number of times woke was negatively associated with GWG and positively associated with psychological health. Findings will inform development of sleep content for future interventions.	Danielle Symons Downs	412
THE DEVELOPMENT OF A MORAL PANIC: A COMPARATIVE ANALYSIS OF IMMIGRATION RHETORIC SURROUNDING THE 2012 AND THE 2016 PRESIDENTIAL ELECTIONS	Madison Harriette Plummer	The 2016 presidential election emphasized the growing divide in our nation as people favored one side over the other. The work presented provides analysis of the 2016 cycle and how it framed immigration, to better understand how the growing racial divide impacted our country at a national and individual level, by answering the following question: In what way did presidential rhetoric surrounding immigration change electorate attitudes in the later start of the 21st century?	Mark Major	411
Temperature effects on corticosterone in the Eastern Fence Lizard, Sceloporus undulatus	Andrea Racic	We tested the effects of temperature on the stress relevant hormone corticosterone in the eastern fence lizard. We assigned lizards to one of four temperatures within their natural range and tested their resulting corticosterone. Both baseline and stress-induced corticosterone were elevated in lizards at higher temperatures, indicating the activity of the physiological stress axis is enhanced at higher temperatures. Investigators should consider temperatures when running field and lab studies as this may affect their results.	Dr. Tracy Langkilde	410
The Influence of Coping Behaviors During a Delay of Gratification Task on Meal Intake in 7-9-Year-Old Children	Ella Lundquist	This is a secondary analysis of data collected during a larger study that assessed the impact of food commercials. The primary aim of this project is to assess if coping behaviors exhibited by children during a delay of gratification task correlated to laboratory meal intake. We found negative correlations between the time children spent looking away and food consumption. This appears to be driven by differences in consumption of high-energy dense foods and food commercials.	Kathleen Keller	409
Shark Sensory Biology and its Role in the Design of Shark Repellent Technology	Aimee Little	Sharks play an important ecological role as apex predators of the ocean. With increased human-shark interactions, there is interest in designing an effective shark repellent that protects both humans and sharks alike; however, progress in this field has stagnated over the last decade. The goals of this project were to examine the current understanding of shark sensory biology and determine how best to use this knowledge in the design of shark deterrent technologies.	Dr. Victoria Braithwaite	408
Molecular Epidemiology of Small Cell Variants of Staphylococcus aureus isolated from dairy herds in Pennsylvania	Alyssa Kamrowski	Recent reports suggest that small cell variants (SCV) of S. aureus can cause persistent infection of the mammary gland in dairy cows. A total of 163 S. aureus isolates from milk samples (2008-2015) were exposed to 2 µg/ml of gentamicin of which 19 parent strains generated SCV. Multi-locus sequence clonal types 15, 97, and 151 accounted for 5.2, 68.4, and 25.3% of the SCVs. respectively. The SCV isolates did not show enhanced resistance to antibiotics.	Bhushan Jayarao	407
Investigating Enhanced Cognitive Performance in Migratory Birds	William Lieb	Behavioral research is commonly conducted using mice and rats, however, avian species possess unique adaptations and characteristics that may provide. We are interested in the resiliency to sleep deprivation exhibited by migratory birds. It has been shown that Zonotrichia leucophrys can perform cognitive tasks well despite restricted sleep. Here, I explore the efficacy of utilizing Zonotrichia albicollis for discovering cognitive protections against sleep restriction.	Paul Bartell	406
IDENTIFICATION OF THE EFFECTS OF SE AND VITAMIN E DEFICIENCY ON THE SEVERITY OF COCCIDIOSIS AND CONCURRENT BOVINE VIRAL DIARRHEA AND CRYPTOSPORIDIUM INFECTIONS IN CATTLE	Lindsay Christine Martin	Coccidiosis is a diarrheal infection that is a major cause of economic and productive loss to cattle producers worldwide. Bovine viral diarrhea virus and Cryptosporidium parvum are other possible etiologic agents for calf diarrhea. This study aims to examine the influence of liver vitamin and mineral levels – primarily selenium – on the severity of coccidiosis in calves. Relationships between coccidiosis and concurrent bovine viral diarrhea virus or Cryptosporidium spp. infections were also explored.	Jason Brooks	405
Impact of Lethal Yellowing Disease on Coconut Production in the Carribean Region	Kayla Rose Stauffer and Katelyn Zembrzycski	Coconut serves as a major source of income for rural families in the Caribbean Regions.The impact of lethal yellowing disease is causing not only a decrease in coconut production but also an increase in price. Factors include social, environmental and economic impacts. Authors: Xavier Fangeyer, Kayla Stauffer, Katelyn Zembrzycski. This poster is a product of INTAG 100 instructed by Mr. Noel Habashy.

Experimental Platform Simulating the Mechanical Effects of Diaphragmatic Motion on Inferior Vena Cava Collapse	Philip Edward Crompton	Inferior vena cava (IVC) filter performance and failure is greatly influenced by IVC hemodynamics, but few studies to date have taken into account the compressive effects of diaphragmatic motion on IVC collapse in the filter region. This work seeks to develop an experimental platform that can reproduce the in vivo deformation of the IVC caused by dynamic diaphragmatic compression under multiple physiological conditions. This model will be validated using a computational model of the IVC.	Keefe Manning	403
Local adaptation and populations’ growth responses to climate in Pinus resinosa	Lauren A Onofrio	A better understanding of genetic and geographic variation within red pine (Pinus resinosa Ait.) is important to determine the effects of a changing climate on this species’ growth and survival. We analyze data from provenance tests to assess intra-specific genetic differentiation and to model populations’ growth response to changes in climate. Results indicate that populations’ responses to climate warming will vary, with populations from warmer summers increasing growth less than those from cooler summers.	Laura Leites	402
