Evaluation Of Coloured Traps With Kairomone Attractant For Monitoring Thrips Population Dynamics On Tomato Crop In East Africa, Alexander Mutua Muvea, Helen Lydia Kutima, Zipporah Osiemo Lagat, Monicah Waiganjo, Sevgan Subramanian

All Peer-Reviewed Publications

Tomato is an important vegetable crop that is cultivated for the domestic market in Kenya and other East African countries. Thrips are one of the key pests hampering the production of tomato, both by direct damage to the crop and as vectors of tospoviruses. Field experiments were carried out over two planting times to evaluate the use of sticky traps for monitoring thrips infesting tomato in East Africa. Blue, yellow, and clear sticky traps with and without a thrips lure (Lurem-TR) were tested. Field observations for thrips catches on the sticky traps were made weekly until crop senescence. Sticky traps …

Genetic Structure And Diversity Of Western Flower Thrips, Frankliniella Occidentalis In A French Bean Agroecosystem Of Kenya, P. Hondelmann, J. O. Nyasani, S. Subramanian, R. Meyhöfer

All Peer-Reviewed Publications

Western flower thrips (WFT) (Frankliniella occidentalis) is an introduced pest that harms French bean production in Kenya and other countries. Since new WFT management approaches are being developed, a closer look at the genetic makeup of WFT populations can give new insights into source habitats, crop colonization patterns or host plant preferences, which are prerequisites for integrated pest management (IPM) strategies. For this purpose, we used six microsatellite loci to analyse the genetic structure, diversity and gene flow of WFT sampled on French beans, intercrops and weeds in Kenyan French bean production areas. The results of this preliminary study indicate …

Evaluation Of Onion (Allium Cepa) Germplasm Entries For Resistance To Onion Thrips, Thrips Tabaci (Lindeman) In Tanzania, Gabriel Michael Njau, Agnes M.S. Nyomora, Fekadu Fufa Dinssa, Jian Cheng Chang, P. Malini, S. Subramanian, R. Srinivasan

All Peer-Reviewed Publications

Onion thrips, Thrips tabaci (Lindeman), is a prominent species infesting onion and tomato in the northern highlands of Tanzania. It causes considerable leaf damage by direct feeding and also transmits the Iris yellow spot virus (IYSV). Hence, one of the objectives of this study was to identify the most resistant onion entries against T. tabaci. One highly resistant (VI038552) and two resistant onion entries (VI038512 and AVON 1067) were identified against T. tabaci. Besides thrips resistance, the bulb size of VI038512 was also equivalent to one of the commercial varieties, Texas. The highly resistant VI038552 recorded the highest yield, followed …

Resolving The Taxonomic Status Of Frankliniella Schultzei (Thysanoptera: Thripidae) Colour Forms In Kenya - A Morphological-, Biological-, Molecular- And Ecological-Based Approach, M. W. Gikonyo, S. Niassy, G. B. Moritz, F. M. Khamis, E. Magiri, S. Subramanian

All Peer-Reviewed Publications

Frankliniella schultzei Trybom is a polyphagous pest and vector of tospoviruses worldwide. It occurs in dark and pale colour forms that are morphologically similar but differ in vector competency and geographic spread. In Kenya and other tropical regions, mixed populations of both colour forms are observed in similar habitats, so are considered as one species. To ascertain the taxonomic status of the two colour forms, they were characterized using morphological, molecular, biological and ecological approaches. Morphological characterization revealed differences between the colour forms on eight features and they separated into distinct clusters through principal component analysis. Restriction fragment length polymorphism …

The Off Season: Masculinities, Rurality, And Family Ties In Alaska Commercial Fishing, Cruz Morey

Senior Theses

This study explores the intersections of masculinity, rurality, the family, and ecology through the experiences of commercial fishermen in Alaska. By understanding the plurality of masculinities and how men operate within a rural space, this study investigates the relationship between the masculine rural and the rural masculine and how that relationship pertains to commercial fishermen. This study examines existing discourse about Alaska and the masculinity of commercial fishermen in light of the concepts of cultural and economic capital, as well as local ecological knowledge (LEK). It further examines how fishermen describe their experiences in the industry as ones that are …

Oldest Skeleton Of A Plesiadapiform Provides Additional Evidence For An Exclusively Arboreal Radiation Of Stem Primates In The Palaeocene, Stephen B. Chester, Thomas E. Williamson, Jonathan I. Bloch, Mary T. Silcox, Eric J. Sargis

Publications and Research

Palaechthonid plesiadapiforms from the Palaeocene of western North America have long been recognized as among the oldest and most primitive euarchontan mammals, a group that includes extant primates, colugos and treeshrews. Despite their relatively sparse fossil record, palaechthonids have played an important role in discussions surrounding adaptive scenarios for primate origins for nearly a half-century. Likewise, palaechthonids have been considered important for understanding relationships among plesiadapiforms, with members of the group proposed as plausible ancestors of Paromomyidae and Microsyopidae. Here, we describe a dentally associated partial skeleton of Torrejonia wilsoni from the early Palaeocene (approx. 62Ma) of New Mexico, which …

The Power Of Prayer, Victoria Dawn Thompson

Capstone Collection

If words are arbitrary, how does prayer have power?” is the question of inquiry in this paper. An unobtrusive Content Analysis inquiry methodology was used to answer this question. The answer lies in the finding that words and thoughts are not the same thing, and our thoughts expand beyond the audible and visible. The implication for professional practice these findings present is that a deeper awareness of “Self” is needed to understand people’s miraculous way of resolving conflict via prayer.

Down Syndrome, The Image Of God, And Personhood, Paris Webb

Dialogue & Nexus

People with Down syndrome help Christians understand what being made in the image of God truly means. After describing Down syndrome, we will examine the different views of the image of God and how these relate to people with Down syndrome. Another approach will be to define personhood in light of God’s image and relate it to Down syndrome. We will use the principles held by the L’Arche community as an exemplar in this discussion to demonstrate that those with Down syndrome encourage us to expand our understanding of the image of God. Consequently, Down’s persons allow us to apply …

Race Relations: A Dialogue Between Science And Theology On The Basis Of Race, Shanice Latham

Dialogue & Nexus

When the topic of race is breached the emotions expressed can range from extreme feelings of guilt to extreme feelings of anger. Why is a word that is, today, commonly associated with a person’s skin color and other physical characteristics responsible for such strong emotional reactions? Much of the violence, poverty, injustice, and hurt in the world has been and is caused by racial division. With the continued use of such an arbitrary system as race these issues will continue to persist and deteriorate. This paper will explore the origin, as well as scientific and theological perspectives of race and …

Feminism In Biology And Belief, Rachel Hurst

Dialogue & Nexus

As feminism has become more hotly-contested in today’s society, the need to analyze the movement’s claims from a scientific and theological perspective has developed. Labor statistics and sociological research reveal that income inequality persists between the sexes. Neuroscience and evolutionary psychology show that subtle differences exist between male and female brains, and these slight variations can potentially be traced to the differing selective pressures between the genders. Ultimately, the biological differences that favor power differentials must be overcome to remedy inequality and injustice. Although Christians have historically upheld these differences and viewed women as inferior, a more modern theological understanding …

Scaling Of Anatomically Derived Maximal Bite Force In Primates, Ashley Deutsch

Senior Theses

Bite force analysis is important the examination of the evolutionary factors that have shaped the masticatory apparatus. Unfortunately, in primates, empirically measured bite force is largely unavailable because of the invasive nature of the procedure. Because of this, we have estimated bite force in a large sample across the primate order at three different realistic bite points along the tooth row: the first maxillary incisor, the maxillary canine, and the paracone of the first maxillary molar. Here, we model bite force by combining measured physiological crosssectional area of the jaw adductors from Hartstone-Rose and colleagues (2017) with osteological measurements from …

The E2f4 Prognostic Signature Predicts Pathological Response To Neoadjuvant Chemotherapy In Breast Cancer Patients, Kenneth M. K. Mark, Frederick S. Varn, Matthew H. Ung, Feng Qian, Chao Cheng

Dartmouth Scholarship

Neoadjuvant chemotherapy is a key component of breast cancer treatment regimens and pathologic complete response to this therapy varies among patients. This is presumably due to differences in the molecular mechanisms that underlie each tumor’s disease pathology. Developing genomic clinical assays that accurately categorize responders from non-responders can provide patients with the most effective therapy for their individual disease. We applied our previously developed E2F4 genomic signature to predict neoadjuvant chemotherapy response in breast cancer. E2F4 individual regulatory activity scores were calculated for 1129 patient samples across 5 independent breast cancer neoadjuvant chemotherapy datasets. Accuracy of the E2F4 signature in …

Investigating the Genetic Basis for Hominoid Taillessness:

A Comparative Genetic Approach Across Ten Catarrhine Taxa

Samantha Tickey-McCrane1,2, Johanna E. Wegener2, and Holly Dunsworth1

Honors Thesis Abstract Written by Samantha Tickey-McCrane, Departments of Anthropology & Biology

Advisor: Dr. Holly Dunsworth, Department of Anthropology

How did hominoid tail loss occur? My goals are to test phylogenetic and adaptive hypotheses for tail length variation among macaques, and use those insights to reconstruct the evolution of hominoid taillessness. Further, I aim to ultimately uncover which candidate genes or pathways may be responsible for catarrhine tail loss, and what other traits may be affected by …

Detecting Cognitive Load During Working Memory Tasks Utilizing A Digitizer Tablet, Cassandra K. Ward, Pradyumn Srivastava

Rehabilitation, Human Resources and Communication Disorders Undergraduate Honors Theses

The purpose of this line of research is to determine whether the ‘Digitizer’ is a reliable and valid way to measure cognitive load during dual working memory-drawing tasks. A quasi-experimental study was conducted at the University of Arkansas in a research laboratory, and participants included seven right-handed healthy adults with normal or corrected vision and no reading difficulty. The participants were selected on a volunteer basis. The study required participants to draw circles while continuously performing in three conditions – one baseline and two working memory experimental tasks, administered in counterbalanced order. The baseline task was to read an 8 …

Does Personality Similarity In Bottlenose Dolphin Pairs Influence Dyadic Bond Characteristics?, Kelsey R. Moreno

Master's Theses

Social structures are critical to the success of many species and have repercussions on health, well-being, and adaptation, yet little is known about the factors which shape these structures aside from ecology and life history strategies. Dyadic bonds are the basis of all social structures; however, mechanisms for formations of specific bonds or patterns in which individuals form which types of bonds have yet to be demonstrated. There is a variety of evidence indicating personality may be a factor in shaping bonds, but this relationship has not been explored with respect to bond components and is yet to be demonstrated …

Laterality Preferences Completing A Tool-Use Task In Asian Small-Clawed Otters (Aonyx Cinereus), Stephanie E. James

Honors Theses

Laterality is defined as the occurrence of each cerebral hemisphere having asymmetric control over the different sides of the body, leading to preferences to use one side of the body over the other for various behaviors. Many types of laterality exist, but handedness is the form that is most predominantly assessed. Handedness in animals is of special interest to laterality researchers, as humans were once thought to be the only species that exhibited lateralized hand preferences. The aim of the current study was to determine if Asian small-clawed otters exhibit significant paw preferences in behaviors associated with completing a tool-use …

Where In The World Are Pallas's Fish Eagles? Migration And Ecology Of Haliaeetus Leucoryphus In Asia, Marla Lynn Steele

Graduate Theses and Dissertations

Pallas’s Fish Eagle (Haliaeetus leucoryphus) is the Northern Hemisphere’s least understood eagle species. Virtually nothing is known concerning the species’ ecology. Historically, Pallas’s Fish Eagles were expected to breed in three separate populations in Mongolia, China, and India and was considered one of the most common raptors in Asia prior to the 1900’s. However, by 1960’s major declines were observed. The species is currently listed as “globally vulnerable” by the International Union for the Conservation of Nature (IUCN) Red List. The current study examined over a century of Pallas’s Fish Eagle observation data to determine occupancy and detection rates throughout …

The Diet And Subsistence Methods Of The Maya: Their Health And Cultural Consequences From The Pre-Classic Era To Today, Rachel E. Watson

Honors Undergraduate

The Maya, a once great civilization, seemingly vanished without an obvious reason, before the Spanish landed in the region. Some say that their downfall was a result of famine and inadequate nutrition. Surprisingly, most of the archaeological evidence surrounding the Classic Maya diet and subsistence methods indicates that they both adequately sustained the population to the point where there has been practically no change over hundreds of years. Change did not occur to the Maya diet or the classic subsistence methods until the late twentieth century when the tourism industry exploded in the area of the former Maya empire. The …

A Longitudinal Cline Characterizes The Genetic Structure Of Human Populations In The Tibetan Plateau, Choongwon Jeong, Benjamin M. Peter, Buddha Basnyat, Maniraj Neupane, Geoff Childs, Sienna Craig, John Novembre, Anna Di Rienzo

Dartmouth Scholarship

Indigenous populations of the Tibetan plateau have attracted much attention for their good performance at extreme high altitude. Most genetic studies of Tibetan adaptations have used genetic variation data at the genome scale, while genetic inferences about their de- mography and population structure are largely based on uniparental markers. To provide genome-wide information on population structure, we analyzed new and published data of 338 individuals from indigenous populations across the plateau in conjunction with world- wide genetic variation data. We found a clear signal of genetic stratification across the east- west axis within Tibetan samples. Samples from more eastern locations …

Health Benefits Of A Plant-Based Diet, Jenna Jackson

Honors Theses

While the rise and spread of Western culture has created remarkable advances in science, healthcare, and technology, it has also brought about a variety of chronic diseases that never once existed. Much of these ailments can be attributed to the typical Western diet, which places heavy emphasis on meats, dairy, and refined grains, contrasting the typical Eastern or Oriental diet which primarily focuses on fruits, vegetables, fish, and whole grains. This dietary transition has resulted in increased glycemic load, increased levels of unhealthy fats and cholesterol, decreased micronutrient and fiber levels, and skewed acid-base and sodium-potassium ratios. All of these …

Repeated Evolution Of Digital Adhesion In Geckos: A Reply To Harrington And Reeder, Tony Gamble, E. Greenbaum, T. R. Jackman, A. P. Russell, A. M. Bauer

Biological Sciences Faculty Research and Publications

We published a phylogenetic comparative analysis that found geckos had gained and lost adhesive toepads multiple times over their long evolutionary history (Gamble et al., PLoS One, 7, 2012, e39429). This was consistent with decades of morphological studies showing geckos had evolved adhesive toepads on multiple occasions and that the morphology of geckos with ancestrally padless digits can be distinguished from secondarily padless forms. Recently, Harrington & Reeder (J. Evol. Biol., 30, 2017, 313) reanalysed data from Gamble et al. (PLoS One, 7, 2012, e39429) and found little support for the multiple origins hypothesis. Here, we …
