Feeding Habits And Dietary Overlap Of Age-0 Winter Flounder (Pseudopleuronectes Americanus) And Summer Flounder (Paralichthys Dentatus) In Southern New England Tidal Rivers, David L. Taylor, Carissa L. Gervasi

Arts & Sciences Faculty Publications

Age-0 winter flounder (Pseudopleuronectes americanus; 20-90 mm in total length [TL]) and summer flounder (Paralichthys dentatus; 19-172 mm TL) were collected from the Seekonk and Taunton Rivers (in Rhode Island and Massachusetts, respectively) from May through September during 2009-2015, and stomach content analysis was used to assess diet composition and resource overlap for these species. Winter and summer flounder underwent ontogenetic dietary shifts. Winter flounder < 40 mm TL predominantly fed on copepods, transitioning to amphipods, isopods, and bivalves with increasing size. Polychaetes also were consumed frequently by winter flounder, irrespective of size. The principal prey of summer flounder < 60 mm TL were mysid shrimp and copepods, whereas sand shrimp (Crangon septemspinosa), amphipods, and fish were the dominant prey of larger conspecifics. There was minimal dietary overlap for the flounder species when comparisons were made independent of body size, indicating food niche segregation. For winter and summer flounder of equivalent sizes, however, dietary overlap was inversely related to TL. Moderate to high resource overlap occurred for small winter and summer flounder (< 40 mm TL) and was attributed to their mutual reliance on copepods and amphipods. Despite evidence of dietary overlap, it is unlikely that shared prey resources were diminished enough to negatively affect either flounder species.

In this article we present and discuss the process of developing and implementing a PBL-based course entitled Moving Images in Teaching and Learning that was held at the University of Lapland, Finland. In the course of the project, this fairly traditional face-to-face course was redesigned into a blended PBL course by integrating Web 2.0 applications into the course. The pedagogical rationale was to support students’ meaningful learning in various phases of the PBL process, and to enable easy storage and sharing of the ideas produced by the students. In addition, the rationale was to create more opportunities for students to …

Penetrance Estimates For Incidental Genomic Findings In Acmg-59, James A. Diao

Yale Day of Data

The dropping costs and rising popularity of next-generation sequencing has introduced the possibility of personalizing medical treatments and screening for genetic diseases. Still, the clinical community’s understanding remains incomplete, with limited consensus on the proper interpretation for many genetic variants. Thus, the standard procedure when returning sequencing results has been to report findings only in genes related to the diagnostic indication, and not incidental findings in other genes. To balance the threat of false positives with the medical benefits of true findings, the American College on Medical Genetics and Genomics (ACMG) recommends an exception: that clinical sequencing laboratories seek and …

Safer Chemicals Design Diagrams, Longzhu Shen, Fjodor Melnikov, John Roethle, Aditya Gudibanda, Richard Judson, Julie Zimmerman, Paul Anastas

Yale Day of Data

The NRF2-ARE antioxidant pathway is an important biological sensing and regulating system that responds to chemical insults. At minute level, it protects a living species to go through hard environmental conditions. However, when the external disruption exceeds the inherent resilience, cellular damage can occur, eventually leading to cytotoxicity. Therefore, studying the likelihood of a chemical activating the NRF2-ARE pathway is interesting to discovering therapeutic agents and designing safer chemicals. In this research, we engaged a combination of computational chemistry, statistical learning and mechanistic toxicology to estimate the likelihood of a chemical to perturb this critical toxicological pathway and derive a …

Do Elephants Eat More Trees When Less Grass Is Available? A Field Study In Kruger National Park, South Africa., Emily Goldberg

Yale Day of Data

Although African bush elephants are often responsible for the majority of herbivore-driven savanna tree mortality, confusion remains regarding the factors that influence their diet. Some elephants either browse or graze almost exclusively, while others balance the two, and the determinants of this variation remain poorly understood. I seek to determine whether grass availability controls the proportion of woody plants in elephant diet and, therefore, the amount of damage elephants do to trees while foraging. Preliminary analysis using already-available data on grass biomass, elephant density, and elephant damage to trees suggest that tree damage is in fact negatively correlated with grass …

Aposematism: An Alternative Hypothesis On How We Discover Medicinal Organisms, Nemer E. Narchi

Journal of Ecological Anthropology

The most widely accepted theories as to how primates select medicinal organisms are based on smelling-tasting bitter, and most of the times toxic, plants (Etkin & Ross, 1982; Johns, 1990). In primates, however, the senses of smell and taste are not as dominant as vision, an evolutionary trait which has been proven to be one of the most favored. I present a perspective claiming that aposematism, the conspicuous coloration displayed by toxic organisms, may play an important role in human recognition of medicinal organisms. This paper represents an open invitation for ecological anthropologists and ethnobiologists to generate empirical data that …

Finding Autonomy: The Impact Of Judicial Discretion For Disabled Individuals In The American Guardianship System, Katherine Davis

Political Science Honors Projects

This study examines the conflict between guardianship and the American disability rights movement, specifically the shift from a medical to a capability model of disability. Legal guardianship presents judges with a dilemma of favoring individual autonomy or societal protection. This dichotomy manifests in the construction of state statutes where legislators can influence judicial discretion and sway decisions. Through analysis of state statutes, case law, and interviews with judges in Connecticut and Minnesota, this study found that higher levels of discretion do not necessarily translate to increased protection of individual autonomy or the use of alternatives to guardianship. The research points …

Wind Wave Behavior In Fetch And Depth Limited Estuaries, Arash Karimpour, Qin Chen, Robert R. Twilley

Faculty Publications

Wetland dominated estuaries serve as one of the most productive natural ecosystems through their ecological, economic and cultural services, such as nursery grounds for fisheries, nutrient sequestration, and ecotourism. The ongoing deterioration of wetland ecosystems in many shallow estuaries raises concerns about the contributing erosive processes and their roles in restraining coastal restoration efforts. Given the combination of wetlands and shallow bays as landscape components that determine the function of estuaries, successful restoration strategies require knowledge of wind wave behavior in fetch and depth limited water as a critical design feature. We experimentally evaluate physics of wind wave growth in …

Impact Of Tigecycline Versus Other Antibiotics On The Fecal Metabolome And On Colonization Resistance To Clostridium Difficile In Mice, Robin L.P. Jump, David Kraft, Kelly Hurless, Alex Polinkovsky, Curtis J. Donskey

Faculty Scholarship

Background: The glycylcycline antibiotic tigecycline may have a relatively low propensity to promote Clostridium difficile infection in part because it causes less disruption of the indigenous intestinal microbiota than other broad-spectrum antibiotics. We used a mouse model to compare the effects of tigecycline versus other commonly used antibiotics on colonization resistance to C. difficile and on the metabolic functions of the intestinal microbiota. Methods: To assess in vivo colonization resistance to C. difficile, mice were challenged with oral C. difficile spores 1, 7, or 12 days after completion of 3 days of treatment with subcutaneous saline, tigecycline, ceftriaxone, piperacillin-tazobactam, or …

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

This paper reports a nanometer-scale investigation of trace element (As, Ca, Cr, Cu, Fe, Mn, Ni, S and Zn) distributions in the root system Spartina alterniflora during dormancy. The sample was collected on a salt marsh island in Jamaica Bay, New York, in April 2015 and the root was cross-sectioned with 10 μm resolution. Synchrotron X-ray nanofluorescence was applied to map the trace element distributions in selected areas of the root epidermis and endodermis. The sampling resolution was 60 nm to increase the measurement accuracy and reduce the uncertainty. The results indicate that the elemental concentrations in the epidermis, outer …

Structural Basis Of Ligand Interaction With Atypical Chemokine Receptor 3, Liwen Wang, Sichun Yang, Mark R. Chance

Faculty Scholarship

Chemokines drive cell migration through their interactions with seven-transmembrane (7TM) chemokine receptors on cell surfaces. The atypical chemokine receptor 3 (ACKR3) binds chemokines CXCL11 and CXCL12 and signals exclusively through β-arrestin-mediated pathways, without activating canonical G-protein signalling. This receptor is upregulated in numerous cancers making it a potential drug target. Here we collected over 100 distinct structural probes from radiolytic footprinting, disulfide trapping, and mutagenesis to map the structures of ACKR3:CXCL12 and ACKR3:small-molecule complexes, including dynamic regions that proved unresolvable by X-ray crystallography in homologous receptors. The data are integrated with molecular modelling to produce complete and cohesive experimentally driven …

Network Dynamics Mediate Circadian Clock Plasticity, Abdelhalim Azzi, Jennifer A. Evans, Tanya Leise, Jihwan Myung, Toru Takumi, Alec J. Davidson, Steven A. Brown

Biological Sciences Faculty Research and Publications

A circadian clock governs most aspects of mammalian behavior. Although its properties are in part genetically determined, altered light-dark environment can change circadian period length through a mechanism requiring de novo DNA methylation. We show here that this mechanism is mediated not via cell-autonomous clock properties, but rather through altered networking within the suprachiasmatic nuclei (SCN), the circadian “master clock,” which is DNA methylated in region-specific manner. DNA methylation is necessary to temporally reorganize circadian phasing among SCN neurons, which in turn changes the period length of the network as a whole. Interruption of neural communication by inhibiting neuronal firing …

Transcriptomic Response Of Wolf Spider, Pardosa Pseudoannulata, To Transgenic Rice Expressing Bacillus Thuringiensis Cry1ab Protein, Juan Wang, Yuande Peng, Kaifu Xiao, Baoyang Wei, Jilin Hu, Zhi Wang, Qisheng Song, Xuguo Zhou

Entomology Faculty Publications

Background: Bacillum thuringiensis (Bt) toxin produced in Cry1-expressing genetically modified rice (Bt rice) is highly effective to control lepidopteran pests, which reduces the needs for synthetic insecticides. Non-target organisms can be exposed to Bt toxins through direct feeding or trophic interactions in the field. The wolf spider Pardosa pseudoannulata, one of the dominant predators in South China, plays a crucial role in the rice agroecosystem. In this study, we investigated transcriptome responses of the 5th instar spiders fed on preys maintained on Bt- and non-Bt rice.

Results: Comparative transcriptome analysis resulted in 136 differentially expressed genes (DEGs) …

The Psychometric Evaluation Of A Personality Selection Tool, James R. Longabaugh

Industrial-Organizational Psychology Dissertations

Personality is one of the primary ways that people are distinguished from one another on the basis of their unique tendencies and behavioral patterns. Decades of empirical research have yielded five primary personality traits which have consistently emerged, becoming known as the Five Factor Model (FFM). In particular, the FFM has been widely used in the employee selection realm. However, there have been mixed reviews as to how well the FFM of personality accomplishes that objective, with some research drawing into question the strength of the relationship between personality and job performance.

The purpose of the current investigation is to …
