Delivering Broadband Light Deep Into Diffusive Media, Rohin Mcintosh, Nicholas Bender, Alexey Yamilov, Arthur Goetschy, Chia Wei Hsu, Hasan Yilmaz, Hui Cao

Physics Faculty Research & Creative Works

Waves propagate diffusively through disordered media, such as biological tissue, clouds, and paint, due to random scattering. Recent advances in optical wavefront shaping techniques have enabled controlling coherent light propagation in multiple-scattering samples. We overcome wave diffusion to deliver optical energy into a target region of arbitrary size and shape anywhere inside a strong-scattering system. This is particularly important for applications such as photoacoustic microscopy and optogenetics, where light needs to be deposited deep into biological tissue. For monochromatic light, we previously introduced the deposition matrix (DM) Z(ω), which maps its input wavefront to the field distribution in the target …

Potential Repercussions Of Offshore Wind Energy Development In The Northeast United States For The Atlantic Surfclam Survey And Population Assessment, Sarah Borsetti, Daphne M. Munroe, Andrew M. Scheld, Eric N. Powell, John M. Klinck, Eileen E. Hofmann

CCPO Publications

The Atlantic surfclam Spisula solidissima fishery, which spans the U.S. Northeast continental shelf, is among the most exposed to offshore wind energy development impacts because of the overlap of fishing grounds with wind energy lease areas, the hydraulic dredges used by the fishing vessels, and the location of vessel home ports relative to the fishing grounds. The Atlantic surfclam federal assessment survey is conducted using a commercial fishing vessel in locations that overlap with the offshore wind energy development. Once wind energy turbines, cables, and scour protection are installed, survey operations within wind energy lease areas may be curtailed or …

Sensitivity Of The Relationship Between Antarctic Ice Shelves And Iron Supply To Projected Changes In The Atmospheric Forcing, Michael S. Dinniman, Pierre St-Laurent, Kevin R. Arrigo, Eileen E. Hofmann, Gert L. Van Dijken

CCPO Publications

Upward advection or mixing of iron-rich deep waters due to circulation changes driven by the rate of basal ice shelf melt was shown to be a primary control on chlorophyll a production in coastal polynyas over the Antarctic continental shelf. Here, the effects of atmospheric changes projected in 2100 on this relationship were examined with a 5-km resolution ocean/sea ice/ice shelf model of the Southern Ocean with different simulated dissolved iron sources and idealized biological uptake. The atmospheric changes are added as idealized increments to the forcing. Inclusion of a poleward shift and strengthening of the winds, increased precipitation, and …

Integrating Human Dimensions In Decadal-Scale Prediction For Marine Social Ecological Systems: Lighting The Grey Zone, Jess Melbourne-Thomas, Desiree Tommasi, Marion Gehlen, Eugene J. Murphy, Jennifer Beckensteiner, Francisco Bravo, Tyler D. Eddy, Mibu Fischer, Elizabeth Fulton, Mayya Gogina, Eileen Hofmann, Maya Ito, Sara Mynott, Kelly Ortega-Cisneros, Anna N. Osiecka, Mark R. Payne, Romeo Saldívar-Lucio, Kim J.N. Scherrer

CCPO Publications

The dynamics of marine systems at decadal scales are notoriously hard to predict-hence references to this timescale as the "grey zone" for ocean prediction. Nevertheless, decadal-scale prediction is a rapidly developing field with an increasing number of applications to help guide ocean stewardship and sustainable use of marine environments. Such predictions can provide industry and managers with information more suited to support planning and management over strategic timeframes, as compared to seasonal forecasts or long-term (century-scale) predictions. The most significant advances in capability for decadal-scale prediction over recent years have been for ocean physics and biogeochemistry, with some notable advances …

Seasonal Habitat Preference And Foraging Behaviour Of Post-Moult Weddell Seals In The Western Ross Sea, Kimberly T. Goetz, Michael S. Dinniman, Luis A. Hückstädt, Patrick W. Robinson, Michelle R. Shero, Jennifer M. Burns, Eileen E. Hofmann, Sharon E. Stammerjohn, Elliott L. Hazen, David G. Ainley, Daniel P. Costa

CCPO Publications

Weddell seals (Leptonychotes weddellii) are important predators in the Southern Ocean and are among the best-studied pinnipeds on Earth, yet much still needs to be learned about their year-round movements and foraging behaviour. Using biologgers, we tagged 62 post-moult Weddell seals in McMurdo Sound and vicinity between 2010 and 2012. Generalized additive mixed models were used to (i) explain and predict the probability of seal presence and foraging behaviour from eight environmental variables, and (ii) examine foraging behaviour in relation to dive metrics. Foraging probability was highest in winter and lowest in summer, and foraging occurred mostly in …

A Growth Model For Arctica Islandica: The Performance Of Tanaka And The Temptation Of Von Bertalanffy—Can The Two Coexist?, John M. Klinck, Eric N. Powell, Kathleen M. Hemeon, Jillian R. Sower, Daniel R. Hennen

CCPO Publications

Organisms increase in size over time (age) due to excess assimilation over metabolic (respiration) energy demands. Most organisms reach a maximum size with increasing age as gain and loss balance. The von Bertalanffy length-at-age relationship, which is commonly used in fishery assessment calculations, imposes such a maximum size. However, some fished species, such as ocean quahogs, Arctica islandica, are long lived and continue to grow at old age. The Tanaka age-at-length relationship has continued growth at old age, but is rarely used in stock assessment models. A modified form of the von Bertalanffy model is presented, which mimics the …

The Southern Ocean Ecosystem Affects The Entire World, Eugene J. Murphy, Nadine M. Johnston, Eileen E. Hofmann, Richard A. Phillips, Jennifer E. Jackson, Andrew J. Constable

CCPO Publications

The Southern Ocean, which flows around the Antarctic continent, is home to vast numbers of unique and remarkable animals, including penguins, albatrosses, petrels, seals, and whales. The ocean bursts into life every spring, fueling a summer feeding and breeding frenzy. During the dark winter months, there is little food and life is very harsh. Human activities such as fishing and pollution are affecting this ecosystem, as is climate change. These ecosystem changes matter beyond the Southern Ocean! Ocean currents carry nutrients and organisms into and out of the Southern Ocean. Many marine mammals and seabirds swim or fly in and …

We expected species with narrow ecological requirements to occupy climatically stable areas, whereas generalists and arboreal species would occupy areas with more variable climate.

Location: South America

Methods: We compiled observations from the scientific literature and herpetological notes (1844-2019) with additional data from museum collections throughout South America to …

A Biodiversity Survey Of The Soil Crusts Of The Geographically Isolated San Nicholas Island, California, Usa And Description Of Species In Three Genera (Atlanticothix, Pycnacronema, Konicacronema) Previously Restricted To Brazil Using A Polyphasic Approach To Cyanobacterial Taxonomy, Brian Jusko

Masters Theses

San Nicholas Island, California, USA is a geographically-isolated island that experiences a semiarid climate and exhibits significant topographic and geologic diversity. Access to the island is restricted to the public and, as a result, only one previous study has been done on the algal biodiversity of its biological soil crusts. The previous study used morphology as the sole basis of species identification, and it was the aim of this study to corroborate and expand upon the results by including molecular data. Using 16S rRNA and 16S–23S ITS sequences and phylogenetic analyses, a diverse set of taxa were identified and are …

More Than The Sum Of Its Parts: Unlocking The Power Of Network Structure For Understanding Organization And Function In Microbiomes, J P. Dundore-Arias, M Michalska-Smith, M Millican, L L. Kinkel

Biology, Agriculture and Chemistry Faculty Publications and Presentations

Plant and soil microbiomes are integral to the health and productivity of plants and ecosystems, yet researchers struggle to identify microbiome characteristics important for providing beneficial outcomes. Network analysis offers a shift in analytical framework beyond "who is present" to the organization or patterns of coexistence between microbes within the microbiome. Because microbial phenotypes are often significantly impacted by coexisting populations, patterns of coexistence within microbiomes are likely to be especially important in predicting functional outcomes. Here, we provide an overview of the how and why of network analysis in microbiome research, highlighting the ways in which network analyses have …

Soil And Compost Tea: A New Restoration Technique?, Carol E. Day

Master's Theses and Doctoral Dissertations

Historically, prairie restorations have lacked the plant diversity seen in remnant prairies. Most restoration practices focus on reestablishing the plant community but overlook the soil microbial community even though microbes are critical to habitat functioning. Developing techniques that increase soil microbes in prairie restorations is critical to ensuring diverse restored habitats. We compared how microbial communities differed between remnant and restored prairie sites. We also investigated if soil and compost teas could be used to reintroduce microbes to restored prairie soil and if the teas affected native plant establishment. We found significant differences in the levels of bacterial taxa between …

A Critical Moral Dilemma Within Animal Law Impact Litigation, Kyla Dayton-Woods

Animal Law Review

Animals, as legal clients, deserve the same rights as people when being represented by attorneys. There is no Model Rule of Professional Conduct to guide attorneys on how to ethically represent their animal clients. This gap in the law demonstrates an uncertainty in how lawyers are meant to fulfill their moral and legal obligations for their animal clients. Using the Nonhuman Rights Project’s representation of two elephant clients, Beulah and Karen, as a test, this Article proposes a Model Rule to fill the moral gap. If this proposed rule was incorporated into the Model Rules, Beulah and Karen’s attorneys may …

Privacy In The Wild: Why Animals' Informational Privacy Matters, Christopher Wlach

Animal Law Review

As data privacy and security come increasingly into focus among lawmakers, regulators, companies, and consumers, concerns about animals’ privacy have gone largely unmentioned. This Article examines how both wild and domestic animals have informational privacy interests—that is, interests in protecting information about themselves. The Article discusses three examples of how informational privacy for animals is not merely a theoretical concept but directly relates to animals’ broader welfare interests. Finally, this Article discusses why privacy provides a helpful theoretical framework and vocabulary for addressing these animals’ interests.

Kangaroo: Fields Of Struggle, Tamasin Ramsay

Animal Law Review

The Kangaroo, a symbol of the Australian landscape, is under attack by the Victoria government. Viewed as overabundant vermin, colonial law often authorizes killing many Kangaroos, a position that is directly at odds with the ancient law and custom of First Nations People. While Victoria law purports to protect the Kangaroo, in reality the current structure does more harm to the animal than good. This Article reviews the fields of struggle represented by the living tension of colonial law and chthonic law in Victoria and suggests genuine collaboration with First Nations and First Peoples to navigate this fraught terrain. Victoria …

From The United States To Pakistan: Can Climate Change Pave Toe Way For An International Right To Animal Rescue In Disasters?, Altamush Saeed

Animal Law Review

Over 69% of the world’s wildlife has been lost between 1970 and 2018. Catastrophic events like the Australian bushfires, the Amazon rainforest fires, and the ongoing floods in the United States have led to the deaths of several billion animals. Ongoing apocalyptic floods have put one-third of Pakistan underwater and led to the deaths of over a million livestock animals. Climate change, human rights, and animal rights have become so intertwined that all life—including human, nonhuman, and plant life—is on the brink of extinction.

Life Cycle Assessment Of Air Classification As A Sulfur Mitigation Technology In Pine Residue Feedstocks, Ashlee Edmonson

Theses and Dissertations--Biosystems and Agricultural Engineering

Sulfur accumulation during biofuel production is pollutive, toxic to conversion catalysts, and causes the premature breakdown of processing equipment. Air classification is an effective preprocessing technology for ash and sulfur removal from biomass feedstocks. A life cycle assessment (LCA) sought to understand the environmental impacts of implementing air classification as a sulfur-mitigation technique for pine residues. Energy demand and material balance for preprocessing were simulated using SimaPro and the Argonne National Laboratory’s GREET model, specifically focusing on comparing the global warming potential (GWP) of grid electricity versus bioelectricity scenarios. Overall, the grid electricity scenario had a GWP impact over 7 …

Masculinity, Femininity, & Dignity: Examining The Relationship Between Gender Expression And Respect, Ashton Lyvers

Mahurin Honors College Capstone Experience/Thesis Projects

The concepts of masculinity and femininity fall into the category of gender, thus making the character qualities we associate with these traits psychological perceptions, rather than biological qualities (Gentile, 1993). Gender roles are not the way one acts, but the way one is expected to act based on their sex (Deaux, 1985). There is a lack of research on how these expectations can create complications in various aspects of our lives, such as feeling respected in our familial or platonic relationships, education, and career. The purpose of this study was to explore the relationship between gender expression and respect. It …

International Journal for the Scholarship of Teaching & Learning

There is a long history of interest in individual differences in learning styles. Beginning in the 1960s, academic research endeavors began examining the concept of personalizing teaching as the best scholarship of teaching and learning best practice (SoTL). This current series of interconnected empirical studies take a fresh look at SoTL by examining students’ self-perception of their learning styles and whether their perceptions relate to how they learn. Today’s college students are growing up in the information age of the 21st Century. Many educators believe that a best practice is to focus on delivering personalized instructional material through technology. Thus, …

“Expanding Our Pedagogical Imagination”: Faculty Experiences With Scholarly Digital Storytelling Across Disciplines, Kelly Schrum

International Journal for the Scholarship of Teaching & Learning

Despite growing pressure to increase technology-enhanced assessment, research has repeatedly demonstrated a lack of widespread meaningful integration of technology in higher education. This is in part due to faculty reluctance which is compounded by lack of training and incentives. This qualitative research grounded in the scholarship of teaching and learning (SoTL) is based on in-depth interviews with 25 faculty internationally, across disciplines and teaching contexts, who integrated scholarly digital storytelling into their pedagogy. It examines their motivations for adopting this technology-enhanced assessment and their experiences implementing it, including increased engagement and student learning.

International Journal for the Scholarship of Teaching & Learning

The writing-to-learn (WTL) literature is varied in how assignments are structured and implemented in the classroom, making it difficult for instructors to identify how to incorporate writing effectively. Drawing on the WTL literature, the MWrite program was established to work with STEM faculty to design, implement, and assess evidence- based WTL assignments. Herein we present a review of the WTL research generated through the MWrite program, situating our findings in a four-dimensional framework of engagement to identify how the MWrite WTL assignment design and implementation has supported students’ learning. Our analysis indicates that the multi-faceted design of MWrite WTL assignments …

Rethinking “Damage-Centered” Research And Individual Solutions: Cultural Humility As A Framework To Increase Student Diversity In Undergraduate Stem Departments, Anita Chikkatur, Stephanie Valle

International Journal for the Scholarship of Teaching & Learning

This study examines data from a participatory research action study on the experiences of underrepresented students in Science, Technology, Engineering, and Mathematics (STEM) fields at a small liberal arts college in the United States. Our analysis aims to move away from the framework that students needed to be taught how to cope with and overcome the challenges they faced in their STEM experiences, including racism and sexism. Instead, we propose a stronger focus on how to end racist, sexist, and other forms of discrimination. We draw on the concept of “cultural humility” as a concrete framework that professors, departments, and …

Heading For A Breakdown: Assessing Evolution Through The Hybridization Of Two Sexual Systems, Diamanda A. Zizis

Honors Theses

Hybridization is an important evolutionary pathway that has contributed to the world’s vast biodiversity. In plants, especially angiosperms, hybridization is known to be an important mechanism for speciation, phenotypic divergence, and changes in reproductive systems. Solanum species present an ideal system to investigate how hybridization between two different sexual systems impacts the reproductive and phenotypic biology of the hybrid progeny. Hybrid seeds were acquired from crosses between Australian Solanum species Solanum dioicum (dioecious) and S. ultraspinosum (andromonoecious) in order to track what happens when you cross two plants with different sexual systems. Vegetative and floral morphological measurements were conducted, and …
