Cumulative Stress Restricts Niche Filling Potential Of Habitat-Forming Kelps In A Future Climate, Nathan G. King, David C. Wilcockson, Richard Webster, Dan A. Smale, Laura S. Hoelters, Pippa J. Moore

Research outputs 2014 to 2021

Climate change is driving range contractions and local population extinctions across the globe. When this affects ecosystem engineers the vacant niches left behind are likely to alter the wider ecosystem unless a similar species can fulfil them.
Here, we explore the stress physiology of two coexisting kelps undergoing opposing range shifts in the Northeast Atlantic and discuss what differences in stress physiology may mean for future niche filling.
We used chlorophyll florescence (F_v/F_m) and differentiation of the heat shock response (HSR) to determine the capacity of the expanding kelp, Laminaria ochroleuca, to move …

Breaking Symmetry In Viral Icosahedral Capsids As Seen Through The Lenses Of X-Ray Crystallography And Cryo-Electron Microscopy., Kristin N. Parent, Jason R. Schrad, Gino Cingolani

Department of Biochemistry and Molecular Biology Faculty Papers

The majority of viruses on Earth form capsids built by multiple copies of one or more types of a coat protein arranged with 532 symmetry, generating an icosahedral shell. This highly repetitive structure is ideal to closely pack identical protein subunits and to enclose the nucleic acid genomes. However, the icosahedral capsid is not merely a passive cage but undergoes dynamic events to promote packaging, maturation and the transfer of the viral genome into the host. These essential processes are often mediated by proteinaceous complexes that interrupt the shell's icosahedral symmetry, providing a gateway through the capsid. In this review, …

Cooperation Through Coordination, Larry Burgess

Materials from the University of Dayton Magazine Website

In college, when you live in a dwelling with a group, everyone takes turns sharing in the chores. Someone cooks, another cleans, there is garbage duty, and perhaps, in northern climates during winter, someone shovels off the front porch. Here, clearing off last night’s sizable snowfall from the front porch of her campus house is, Casey Boland, senior environmental biology major from Cincinnati.

Mixing It Up In The Ocean Carbon Cycle And The Removal Of Refractory Dissolved Organic Carbon, Yuan Shen, Ronald Benner

Faculty Publications

A large quantity of reduced carbon is sequestered in the ocean as refractory dissolved molecules that persist through several circuits of global overturning circulation. Key aspects of the cycling of refractory dissolved organic carbon (DOC) remain unknown, making it challenging to predict how this large carbon reservoir will respond to climate change. Herein we investigate mechanisms that remove refractory DOC using bioassay experiments with DOC isolated from surface, mesopelagic and deep waters of the Atlantic Ocean. The isolated DOC was refractory to degradation by native microbial communities, even at elevated concentrations. However, when the refractory DOC was introduced to a …

Lower Dietary Inflammatory Index Scores Are Associated With Lower Glycemic Index Scores Among College Students, Yeonsoo Kim, Jie Chen, Michael Wirth, Nitin Shivappa, James R. Hébert

Faculty Publications

The association between the Dietary Inflammatory Index (DII^®), the glycemic index (GI), and the glycemic load (GL) is not known, although it is known that carbohydrates are pro-inflammatory. We aimed to measure the association between the DII and both GI and GL among college students. In this cross-sectional study, 110 college students completed a 3-day food diary, which was used to calculate the DII, the GI, the GL, and the healthy eating index (HEI)-2010. Least square means and 95% confidence intervals of the GI, the GL, and the HEI-2010 were presented per DII tertile using generalized linear mixed …

Supramolecular Aptamer Nano-Constructs For Receptor-Mediated Targeting And Light-Triggered Release Of Chemotherapeutics Into Cancer Cells, Deepak K. Prusty, Volker Adam, Reza M. Zadegan, Stephan Irsen, Michael Famulok

Materials Science and Engineering Faculty Publications and Presentations

Platforms for targeted drug-delivery must simultaneously exhibit serum stability, efficient directed cell internalization, and triggered drug release. Here, using lipid-mediated self-assembly of aptamers, we combine multiple structural motifs into a single nanoconstruct that targets hepatocyte growth factor receptor (cMet). The nanocarrier consists of lipidated versions of a cMet-binding aptamer and a separate lipidated GC-rich DNA hairpin motif loaded with intercalated doxorubicin. Multiple 2′,6′-dimethylazobenzene moieties are incorporated into the doxorubicin-binding motif to trigger the release of the chemotherapeutics by photoisomerization. The lipidated DNA scaffolds self-assemble into spherical hybrid-nanoconstructs that specifically bind cMet. The combined features of the nanocarriers increase serum nuclease …

Repeated Measures Of Blood And Breath Ammonia In Response To Control, Moderate And High Protein Dose In Healthy Men., Lisa A. Spacek, Arthur Strzepka, Saurabh Saha, Jonathan Kotula, Jeffrey Gelb, Sarah Guilmain, Terence Risby, Steven F. Solga

Department of Medicine Faculty Papers

Ammonia physiology is important to numerous disease states including urea cycle disorders and hepatic encephalopathy. However, many unknowns persist regarding the ammonia response to common and potentially significant physiologic influences, such as food. Our aim was to evaluate the dynamic range of ammonia in response to an oral protein challenge in healthy participants. We measured blood and breath ammonia at baseline and every hour for 5.5 hours. Healthy men (N = 22, aged 18 to 24 years) consumed a 60 g protein shake (high dose); a subset of 10 consumed a 30 g protein shake (moderate dose) and 12 consumed …

Cd38/Cadpr Signaling Pathway In Airway Disease: Regulatory Mechanisms, Deepak A. Deshpande, Phd, Alonso G. P. Guedes, Richard Graeff, Soner Dogan, Subbaya Subramanian, Timothy F. Walseth, Mathur S. Kannan

Department of Medicine Faculty Papers

Asthma is an inflammatory disease in which proinflammatory cytokines have a role in inducing abnormalities of airway smooth muscle function and in the development of airway hyperresponsiveness. Inflammatory cytokines alter calcium (Ca2+) signaling and contractility of airway smooth muscle, which results in nonspecific airway hyperresponsiveness to agonists. In this context, Ca2+ regulatory mechanisms in airway smooth muscle and changes in these regulatory mechanisms encompass a major component of airway hyperresponsiveness. Although dynamic Ca2+ regulation is complex, phospholipase C/inositol tris-phosphate (PLC/IP3) and CD38-cyclic ADP-ribose (CD38/cADPR) are two major pathways mediating agonist-induced Ca2+ regulation in airway smooth muscle. Altered CD38 expression or …

Using Natural Resources To Control The Fate Of Contaminants In The Environment, Lucia Rodriguez Freire

Sustainability Seminar Series

Environmental contamination poses an increased health risk to those communities living nearby impacted sites, and it is imperative to find sustainable remediation strategies to restore the natural systems. My research investigates natural biogeochemical processes and the use of ubiquitous materials to the design remediation solutions that are site-specific and take into consideration the needs of the affected communities. The first example is the investigation of uranium (U) accumulation in plants growing along the Rio Paguate, which flows through the Jackpile Mine, and open-pit U mine listed on the National Priority List as a Superfund site. Two villages of the Laguna …

Evaluating Multiple Arthropod Taxa As Indicators Of Invertebrate Diversity In Old Fields, William R. Morrison Iii, Joseph T. Waller, Alyssa C. Brayshaw, David A. Hyman, Michael R. Johnson, Ann M. Fraser

The Great Lakes Entomologist

Biodiversity, often quantified by species richness, is commonly used to evaluate and monitor the health of ecosystems and as a tool for conservation planning. The use of one or more focal taxa as surrogates or indicators of larger taxonomic diversity can greatly expedite the process of biodiversity measurement. This is especially true when studying diverse and abundant invertebrate fauna. Before indicator taxa are employed, however, research into their suitability as indicators of greater taxonomic diversity in an area is needed. We sampled invertebrate diversity in old fields in southern Michigan using pitfall trapping and morphospecies designations after identification to order …

Bees (Hymenoptera: Apoidea) Of The Chicago Area: Diversity And Habitat Use In An Urbanized Landscape, Alan Molumby, Tomasz Przybylowicz

The Great Lakes Entomologist

Bees (Hymenoptera: Apoidea) were collected at 24 sites chosen to represent the diversity of urban and natural habitats in the Chicago metropolitan area. Species richness was assessed for each site. Patterns of habitat use were inferred from collection records. In urban areas, we collected 33 species, belonging to 15 genera and 5 families. Areas of preserved natural habitat yielded 44 species, in 20 genera, and 6 families. Twenty species were common to both urban areas and areas of preserved natural habitat. Species at each site were ranked by the number of times they were collected. The bees most often collected …

Does Low-Density Grazing Affect Butterfly (Lepidoptera) Colonization Of A Previously Flooded Tallgrass Prairie Reconstruction?, Abbey Elmer, Jamie Lane, Keith S. Summerville, Loren Lown

The Great Lakes Entomologist

Conservation of wildlife in managed landscapes can be facilitated by partnering with livestock producers to introduce grazing disturbances. The effects of grazing in grassland systems, however, are often a function of other disturbances that may occur simultaneously. The goal of this study was to determine how grazing and flooding disturbances interacted to affect butterfly communities on wetland reserve program easements. We sampled butterflies from 2008-2011 in two large grassland habitats, one exposed to low density cow-calf grazing and one maintained as a control. Both grassland habitats were severely flooded in 2008. Repeated-measures ANOVA suggested that time since flooding and the …

Predicting Emerald Ash Borer, Agrilus Planipennis (Coleoptera: Buprestidae), Landing Behavior On Unwounded Ash, Jordan M. Marshall, Melissa J. Porter, Andrew J. Storer

The Great Lakes Entomologist

Detection of emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), an invasive forest pest, is difficult in low density populations war- ranting continual development of various trapping techniques and protocols. Understanding and predicting landing behavior of A. planipennis may assist in the further development of trapping techniques and improvement of trapping protocols for widespread survey programs in North America. Three multiple regression models were developed using ash tree vigor and crown light exposure to predict the landing behavior of A. planipennis. These models were then used to predict the landing density of A. planipennis at separate sites and in …

Endophytic Fungi Of Bitter Melon (Momordica Charantia) In Guangdong Province, China, Jiang-Hua Huang, Mei-Mei Xiang, Zi-De Jiang

The Great Lakes Entomologist

Endophytic fungi can mutualistically interact with their host plants by deterring herbivores. Overall 1172 endophytic fungal isolates were recovered from roots, stems, leaves, flowers and fruits of bitter melon, Momordica charantia, at five sites in Guangdong Province. These isolates were identified to 25 genera using morphological and molecular characteristics. The endophyte communities at the five sites were similar. Alternaria alternata, Aspergillus spp., Cladosporium spp., Colletotrichum spp., Nigrospora spp., Penicillium spp., Arthrinium spp., Chaetimium spp., Curvularia spp., Fusarium spp., Phoma spp., and Phomopsis spp. were isolated from at least three of the five sites. The coefficient of similarity for endophytes …

Activity And Diversity Of Collembola (Insecta) And Mites (Acari) In Litter Of A Degraded Midwestern Oak Woodland, James F. Steffen, Joan Palincsar, Florrie M. Funk, Daniel J. Larkin

The Great Lakes Entomologist

Litter-inhabiting Collembola and mites were sampled using pitfall traps over a twelve-month period from four sub-communities within a 100-acre (40-ha) oak-woodland complex in northern Cook County, Illinois. Sampled locations included four areas where future ecological restoration was planned (mesic woodland, dry-mesic woodland, mesic upland forest, and buckthorn-dominated savanna) and a mesic woodland control that would not be restored. Fifty-eight mite and 30 Collembola taxa were identified out of 5,308 and 190,402 individuals trapped, respectively. There was a significant positive relationship between litter mass and both mite diversity and the ratio of Oribatida to Prostigmata and a significant negative relationship between …

Religion Lessons From Europe: Intolerant Secularism, Pluralistic Neutrality, And The U.S. Supreme Court, Antony Barone Kolenc

Pace International Law Review

Case law from the European Court of Human Rights demonstrates to the U.S. Supreme Court how a pluralistic neutrality principle can enrich the American society and harness the value of faith in the public sphere, while at the same time retaining the vigorous protection of individual religious rights. The unfortunate alternative to a jurisprudence built around pluralistic neutrality is the inevitability of intolerant secularism—an increasingly militant separation of religious ideals from the public life, leading ultimately to a repressive society that has no room in its government for religious citizens. The results of intolerant secularism are seen in a recent …
