Investigating The Nightime Departures Of Glaucous-Winged Gulls (Larus Glaucescens) And The Role Of Social Facilitation, Devon Leigh Mcclain

Master's Theses

Daytime behaviors and occupancy patterns of Glaucous-winged Gulls (Larus glaucescens) have been described and can be mathematically predicted based on environmental factors. However, little is known about the nighttime behaviors of Glaucous-winged Gulls. I used trail cameras to study the daytime and nighttime colony occupancy patterns of Glaucous-winged Gulls on a breeding colony on Protection Island, Washington, USA. Early in the breeding season gulls desert the colony en masse during nighttime even after some gulls have initiated clutches. Using acoustic recording units to identify an acoustic cue that signals the onset of the coordinated nightly departures from the colony, I …

A Study Of Inactive Enzyme-Homologues: The Biochemical And Biological Function Of Ecm14 In Saccharomyces Cerevisiae, Robert Christian Mcdonald

Master's Theses

Like most major enzyme families, the M14 family of metallocarboxypeptidases (MCPs) contains several pseudoenzymes predicted to lack enzyme activity and with unknown molecular function. The genome of the yeast Saccharomyces cerevisiae encodes only one member of the M14 MCP family, a pseudoenzyme named Ecm14 proposed to function in the extracellular matrix. Ecm14 is found throughout ascomycete fungi, with a group of related pseudoenzymes found in basidiomycetes. Although the prodomain of Ecm14 can be cleaved in vivo and in vitro by endopeptidases, suggesting an activation mechanism, no activity has been detected using standard carboxypeptidase substrates.

In order to examine the function …

Ecological Mechanisms Explaining Interactions Within Plant–Hummingbird Networks: Morphological Matching Increases Towards Lower Latitudes, J Sonne, J Vizentin-Bugoni, Pk Maruyama, Ac Araujo, E Chávez-González, Ag Coelho, Pa Cotton, Oh Marín-Gómez, C Lara, Lr Lasprilla, Cg Machado, Ma Maglianesi, Ts Malucelli, Amm González, Gm Oliveira, Pe Oliveira, R Ortiz-Pulido, Ma Rocca, Lc Rodrigues, I Sazima, Bi Simmons, B Tinoco, Ig Varassin, Mf Vasconcelos, B O'Hara, M Schleuning, C Rahbek, M Sazima, B Dalsgaard

Interactions between species are influenced by different ecological mechanisms, such as morphological matching, phenological overlap and species abundances. How these mechanisms explain interaction frequencies across environmental gradients remains poorly understood. Consequently, we also know little about the mechanisms that drive the geographical patterns in network structure, such as complementary specialization and modularity. Here, we use data on morphologies, phenologies and abundances to explain interaction frequencies between hummingbirds and plants at a large geographical scale. For 24 quantitative networks sampled throughout the Americas, we found that the tendency of species to interact with morphologically matching partners contributed to specialized and modular …

Microplastic Accumulation In Deep-Sea Sediments From The Rockall Trough, Winnie Courtene-Jones, Brian Quinn, Ciaran Ewins, Stefan F. Gary, Bhavani E. Narayanaswamy

School of Biological and Marine Sciences

Microplastics are widely dispersed through the marine environment. Few studies have assessed the long-term or historic prevalence of microplastics, yet acquiring such data can inform their distribution, transport and the environmental risks posed. To quantify the distribution and polymer types temporally, sediment cores were collected from >2000 m water depth in the Rockall Trough, North Atlantic Ocean. As hypothesized, a significant negative trend was observed in the frequency of microplastics with increasing sediment age, however there was an increase in polymer diversity. Microplastics were pervasive throughout the sediment analysed (10 cm depth), yet lead-210 (210Pb) activities were confined to the …

Occurrence And Assemblage Composition Of Intertidal Non-Native Species May Be Influenced By Shipping Patterns And Artificial Structures, Kathryn A. O'Shaughnessy, Stephen J. Hawkins, Anna L.E. Yunnie, Mick E. Hanley, Paul Lunt, Richard C. Thompson, Louise B. Firth

School of Biological and Marine Sciences

Habitat modification coupled with the spread of non-native species (NNS) are among the top threats to marine biodiversity globally. Species are known to be transported to new locations via international shipping and secondarily spread via regional vessels and artificial structures. Rapid Assessment Surveys (RAS) combining quantitative and semi-quantitative methods compared NNS richness and assemblage composition on intertidal natural rocky shores and artificial structures in harbours in different regions along the south coast of England. Quantitative data showed that artificial habitats supported higher richness than natural habitats, while semi-quantitative data found no difference in richness among habitat types. This result was …

School of Biological and Marine Sciences

The goal of this paper is to propose a screening method for assessing the environmental risk to aquatic systems in harbours worldwide. A semi-quantitative method is based on environmental pressures, environmental conditions and societal response. The method is flexible enough to be applied to 15 harbours globally distributed through a multinational test using standardised and homogenised open data that can be obtained for any port worldwide. The method emerges as a useful approach towards the foundation of a global environmental risk atlas of harbours that should guide the harbour sector to develop a more globally informed strategy of sustainable development.

First Man And Second Woman: Reflections On The Anniversaries Of Apollo 11 And Cruzan, George J. Annas

Faculty Scholarship

THE United States Supreme Court's decision in Cruzan v. Director, Missouri Department of Health marks its thirtieth anniversary in 2020.' This follows closely after the fiftieth anniversary of the Apollo 11 moon landing.² Anniversaries provide an opportunity for reflection and to gain perspective. We can, I suggest, gain deeper insights regarding human life and death by considering these two anniversaries together. Apollo 11 may seem far from Nancy Cruzan-but the discovery of disturbing details about the death of Neil Armstrong, the first man on the moon, is a productive introduction to the topic of death in a modern American …

Brief Of Amici Curiae Scholars Of The Constitutional Rights And Interests Of Children In Support Of Respondents, Angela Onwuachi-Willig, Catherine E. Smith, Tanya Washington Hicks, Lauren Fontana, Jessica Dixon Weaver, Cary Martin Shelby

Faculty Scholarship

This Brief of Amici Curiae Scholars of the Constitutional Rights and Interests of Children in Support of Respondents filed in Fulton v. City of Philadelphia makes two points. First, a categorical exemption, based on religious beliefs rather than foster children’s needs, does not serve the best interests of children and violates the government’s duty to foster youth. Such an exemption needlessly restricts the pool of prospective foster parents, increasing the risk of a greater number of children being confined to long-term, institutional care. The reduction of same-sex foster parents would also have a disproportionate impact on “special needs” and LGBT …

Capitalizing On Healthy Lawyers: The Business Case For Law Firms To Promote And Prioritize Lawyer Well-Being, Jarrod F. Reich

Faculty Scholarship

This Article is the first to make the business case for firms to promote and prioritize lawyer well-being. For more than three decades, quantitative research has demonstrated that lawyers suffer from depression, anxiety, and addiction far in excess of the general population. Since that time, there have been many calls within and outside the profession for changes to be made to promote, prioritize, and improve lawyer well-being, particularly because many aspects of the current law school and law firm models exacerbate mental health and addiction issues, as well as overall law student and lawyer distress. These calls for change, made …

Aging And Efficacy Of Disease-Modifying Therapies In Multiple Sclerosis: A Meta-Analysis Of Clinical Trials, Yinan Zhang, Natalia Gonzalez Caldito, Afsaneh Shirani, Amber Salter, Gary Cutter, William Culpepper, Mitchell Wallin, Peter Kosa, Bibiana Bielekova, Fred Lublin, Olaf Stuve

2020-Current year OA Pubs

Background: Disease-modifying therapies (DMTs) for multiple sclerosis (MS) are approved for the treatment of disease activity and are effective in reducing relapses and new magnetic resonance imaging (MRI) lesions. However, disease activity generally subsides with time, and age-dependent changes in DMT efficacy are not well-established. We aimed to investigate whether age impacts the efficacy of DMTs in treating disease activity in patients with relapsing-remitting MS (RRMS).

Methods: DMT efficacy related to age was assessed through a meta-analysis of clinical trials that evaluated the efficacy of DMTs in RRMS patients as measured by reductions in the annualized relapse rate (ARR), new …

Semi-Automated Segmentation Of The Lateral Periventricular Regions Using Diffusion Magnetic Resonance Imaging, Albert M Isaacs, Rowland H Han, Christopher D Smyser, David D Limbrick, Joshua S Shimony

2020-Current year OA Pubs

The lateral ventricular perimeter (LVP) of the brain is a critical region because in addition to housing neural stem cells required for brain development, it facilitates cerebrospinal fluid (CSF) bulk flow and functions as a blood-CSF barrier to protect periventricular white matter (PVWM) and other adjacent regions from injurious toxins. LVP injury is common, particularly among preterm infants who sustain intraventricular hemorrhage or post hemorrhagic hydrocephalus and has been associated with poor neurological outcomes. Assessment of the LVP with diffusion MRI has been challenging, primarily due to issues with partial volume artifacts since the LVP region is in close proximity …

Science Into Practice: Effective Solutions For Social Isolation And Loneliness., Julianne Holt-Lunstad, Ryan Layton, Bonnie Barton, Timothy B. Smith

Faculty Publications

Robust research evidence confirms the adverse health effects of social isolation and loneliness, with increasing focus on finding effective solutions. What can we extract from epidemiology and relationship science to help us design more effective solutions? This article identifies themes in contemporary scholarship that inform effective program and intervention design. The themes include: (1) multiple underlying causal factors that may require tailored approach; (2) the time course of relationships and disease development versus length of interventions; (3) the protective effects of relationships are based on naturally occurring or existing close relationships, yet most programs involve strangers; and (4) not all …
