The mechanisms underpinning concussion, traumatic brain injury, and chronic traumatic encephalopathy, and the relationships between these disorders, are poorly understood. We examined post-mortem brains from teenage athletes in the acute-subacute period after mild closed-head impact injury and found astrocytosis, myelinated axonopathy, microvascular injury, perivascular neuroinflammation, and phosphorylated tau protein pathology. To investigate causal mechanisms, we developed a mouse model of lateral closed-head impact injury that uses momentum transfer to induce traumatic head acceleration. Unanaesthetized mice subjected to unilateral impact exhibited abrupt onset, transient course, and rapid resolution of a concussion-like syndrome characterized by altered arousal, contralateral hemiparesis, truncal ataxia, locomotor …

Condition-Dependence Of Blue Plumage Coverage In Indigo Buntings Passerina Cyanea, Spencer B. Hudson, Travis E. Wilcoxen

Biology Faculty Publications

Nuptial plumage colouration is seemingly favoured by females of avian species with regards to sexual selection. This particular secondary sexual characteristic has been previously shown to be a condition-dependent signal of individual quality among passerines with pigment-based colouration (i.e. yellows and reds). In contrast, relationships between structural plumage colouration (i.e. blues) and aspects of both physical quality and physiological function have been understudied. Using free-living Indigo Buntings (Passerina cyanea) as a study species, we compared the percentage of blue feather coverage to body condition, innate immune responses, antioxidant capacity, stress physiology, reproductive physiology, and …

Additions And Corrections To The Stoneflies (Plecoptera) Of Iowa, U.S.A., Dennis P. Heimdal, Michael W. Birmingham

The Great Lakes Entomologist

(exerpt)

Until recently, Iowa’s stonefly fauna was poorly documented. Heimdal et al. (2004) published a comprehensive report on stonefly distributions within the state, reporting seven families and 43 species. Five species, Allocapnia pygmaea (Burmeister) (Capiniidae), Leuctra tenuis (Pictet) (Leuctridae), Amphinemura linda (Ricker) (Nemouridae), Nemoura trispinosa Claassen (Nemouridae), and Soyedina vallicularia (Wu) (Nemouridae), were recommended for state protection because of their limited distribution within Iowa. Four species, Amphinemura delosa (Ricker), Isogenoides doratus (Frison) (Perlodidae), I. krumholzi (Ricker), and I. varians (Walsh), had limited distributions, but were not listed because their observed habitat preferences appeared common or were difficult to sample and …

First Record Of Harpalus Ochropus Kirby (Coleoptera: Carabidae) From Minnesota And The Conterminous United States, Foster Forbes Purrington, Richard M. Maxey

The Great Lakes Entomologist

(excerpt)

The epigeal ground beetle Harpalus ochropus Kirby (Coleoptera: Carabidae) has been reported from Alaska and across Canada from British Columbia into Quebec (Bousquet and Larochelle 1993). It is local and rarely collected. Gandhi et al. (2005) surveyed for carabids extensively for several years along the Gunflint Trail and adjacent Boundary Waters Canoe Area in northeastern Minnesota.

A Friend Unmasked: Notes On Chauliognathus Pensylvanicus (Coleoptera: Cantharidae) And The Nature Of Natural History, Andrew H. Williams

The Great Lakes Entomologist

Data from field observations from 1992 through 2006 and from museum specimens of adult Chauliognathus pensylvanicus (DeGeer) from Wisconsin are presented here, with information from the literature. Beetles were found using flowers of 183 species in 29 families growing outside cultivation in Wisconsin and in every Wisconsin county. All evidence supports the characterization of C. pensylvanicus as a prairie insect that also lives in other, early successional plant communities.

Patch-Scale Movement Dynamics In The Iowa Grassland Butterflies Speyeria Cybele And Megisto Cymela (Lepidoptera: Nymphalidae), David Courard-Hauri, Ashley A. Wick, Lindsey K. Kneubuhler, Keith S. Summerville

The Great Lakes Entomologist

An understanding of the movement dynamics of invertebrates can be critical to their conservation, especially when managing relatively small, isolated habitats. Most studies of butterfly movement have focused on metapopulation dynamics at relatively large spatial scales, and the results from these studies may not translate well for patchy populations within a single nature preserve. In this work we use individual mark and recapture (IMR) methods to follow the movements of two species of butterfly, Megisto cymela (Cramer) and Speyeria cybele F. (Lepidoptera: Nymphalidae) within a 240 hectare forest and grassland preserve in central Iowa, USA. Significant redistribution was seen in …

Anoplophora Glabripennis Within-Tree Distribution, Seasonal Development, And Host Suitability In China And Chicago, Robert A. Haack, Leah S. Bauer, Rui-Tong Gao, Joseph J. Mccarthy, Deborah L. Miller, Toby R. Petrice, Therese M. Poland

The Great Lakes Entomologist

Established populations of the Asian longhorned beetle, Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae), were first reported in the United States in New York in 1996, Illinois in 1998, and New Jersey in 2002. A federal quarantine and an eradication program were implemented in 1997, involving tree surveys and removal of infested trees. We recorded the number of A. glabripennis life stages found at several locations along the main trunk and major branches of naturally infested trees in China (species of Populus, Salix, and Ulmus) and Chicago, Illinois (species of Acer, Fraxinus, and Ulmus) during 1999 to 2002. Typically, …

Variation In Detecting Schinia Indiana And Schinia Lucens (Lepidoptera: Noctuidae) In Wisconsin, Ann B. Swengel, Scott R. Swengel

The Great Lakes Entomologist

Schinia indiana (Smith) and Schinia lucens (Morrison) (Lepidoptera: Noctuidae) are diurnal moths and are well camouflaged when perched on flowers of their larval food plants: Phlox pilosa L. (Polemoniaceae) and Amorpha(Fabaceae), respectively. We recorded 264 S. indiana in diurnal surveys of 28 units of 15 sites in Jackson County, WI, and 25 units of 5 sites in Burnett County, WI, from 23 May (2006) to 15 June (1994). The longest flight periods in single years were 21 days in 1994 and 17 days in 2006. Abundance of individuals was significantly greater when phlox flowering was prepeak and peak, compared …

Variation In Diel Activity Of Ground Beetles (Coleoptera: Carabidae) Associated With A Soybean Field And Coal Mine Remnant, Jason E. Willand, Kenneth W. Mccravy

The Great Lakes Entomologist

Diel activities of carabids (Coleoptera: Carabidae) associated with a coal mine remnant and surrounding soybean field were studied in west-central Illinois from June through October 2002. A total of 1,402 carabids, representing 29 species and 17 genera, were collected using pitfall traps. Poecilus chalcites (Say) demonstrated roughly equal diurnal and nocturnal activity in June, but greater diurnal activity thereafter. Pterostichus permundus (Say), Cyclotrachelus seximpressus (LeConte), Amara obesa (Say), and Scarites quadriceps Chaudoir showed significant nocturnal activity. Associations between habitat and diel activity were found for three species: P. chalcites associated with the remnant and edge habitats showed greater diurnal activity …

Diversity Of Cicadellidae And Cercopidae (Hemiptera) On Sand Prairies Of Newaygo County, Michigan, James P. Dunn, Holly A. Hereau, Adam J. Klomp

The Great Lakes Entomologist

Sand prairies in the Great Lakes region occur as small sites dispersed through- out a heavily disturbed landscape. These unique natural areas are dominated by dry prairie grasses and are inhabited by a diversity of insects of which Cicadellidae and Cercopidae are among the most diverse groups. Their species compositions have been implicated as being potential indicators of ecological quality that could be used to rank the quality of prairie vegetation. In Newaygo Co., Michigan, 12 sand prairies were surveyed for Cicadellidae and Cercopidae and these data were then used to estimate species diversity for each site by the Simpson’s …

Oviposition And Development Of Emerald Ash Borer (Agrilus Planipennis) (Coleoptera: Buprestidae) On Hosts And Potential Hosts In No-Choice Bioassays, Andrea C. Anulewicz, Deborah G. Mccullough, Deborah L. Miller

The Great Lakes Entomologist

Emerald ash borer (Agrilus planipennis Fairmaire) (Coleoptera: Bupres- tidae) is an invasive phloem-feeding pest native to Asia. It was first identified in North America in 2002 and has killed millions of ash (Fraxinus spp.) trees in southeast Michigan and Essex County, Ontario. Since then, additional populations have been discovered across Michigan and in areas of Ohio, Indiana, Illinois, Maryland, Pennsylvania and West Virginia. In Asia, A. planipennis reportedly colonizes other genera, including species of Juglans, Pterocarya and Ulmus. In North America, attacks on non-ash species have not been observed but there is concern about host switching as …

A Field Guide To The Tiger Beetles Of The United States And Canada: Identification, Natural History, And Distribution Of The Cicindelidae. D. L. Pearson, D. B. Knisley, And D. J. Kazilek. 2006. Oxford University Press, 227 Pp., Soft Cover., Kamal J.K. Gandhi

The Great Lakes Entomologist

(excerpt)

Tiger Beetles are a favorite among insect collectors because of their beauty, diversity, and fascinating adult and larval behavior. Cicindelophiles, or tiger beetle enthusiasts, have been blessed during the past decade as a number of regional field-guides have been published on these insects (Knisley and Schultz 1997, Leonard and Bell 1999, Acorn 2001, Pearson and Vogler 2001, Choate 2003). However, missing from the shelf was a book about the synthesis of tiger beetles of America north of Mexico, and this book fills exactly that much coveted empty space on the entomologist’s book-shelf.

Isodontia Elegans Now In Michigan (Hymenoptera: Sphecidae: Sphecinae), Mark F. O'Brien, Julie A. Craves

The Great Lakes Entomologist

Isodontia elegans (Smith) (Hymenoptera: Sphecidae), one of the “grass- carrying wasps,” previously known only from the western U.S., is now reported from southeastern Michigan, and appears to have spread across the eastern half of the United States in a relatively short period.

Math In Seventeen Syllables: A Folder Of Mathematical Haiku

Journal of Humanistic Mathematics

In our July 2017 issue, we issued an open call for mathematical haiku, which we defined to be a three-line poem in the “5-7-5” syllabic form that expressed a mathematical idea or experience, and hopefully connected it to the human condition. In deference to traditional Japanese haiku, we encouraged poets to consider using allusions to nature or the seasons in their work, or what is known as a caesura or kire represented by punctuations, space, line-break, or other grammatical break that is intended to compare two images implicitly.

We received haiku on an amazing variety of themes and subjects, from …

Mathematicians Versus Philosophers In Recent Work On Mathematical Beauty, Viktor Blåsjö

Journal of Humanistic Mathematics

Recent attempts at defining mathematical beauty fall roughly into two schools of thought. One takes its starting point in the subjective experience of the mathematician and characterises mathematical beauty in cognitive terms. The other seeks to reduce beauty to objective notions such as truth, symmetry, or simplicity. This second approach is popular among analytic philosophers, who are committed to seeing mathematics and science as prototypically rational enterprises. I criticise this stance on the grounds that this commitment makes its supporters approach beauty in mathematics not with a genuine desire to sympathetically understand it, but with the preconceived goal of explaining …

My Sets And Sexuality, Andres Sanchez

Journal of Humanistic Mathematics

It was only with the application of set theory to my own personal life that I discovered my true identity and sexuality. In this exploratory, personal essay, I detail my own discovery of my sexuality through mathematics and how this math has become a lens through which I view the world. And, with new knowledge of literary criticism in hand, I can now retroactively describe the thoughts I had in this discovery process.

Mathematics, Writing, And Rhetoric: Deep Thinking In First-Year Learning Communities, Christine Von Renesse, Jennifer Digrazia

Journal of Humanistic Mathematics

Through the process of combining two seemingly unlikely bedfellows, mathematics and composition, two instructors explain how rhetoric connects the art of writing and the art of doing mathematics in an inquiry-based learning community. Combining these two courses in a learning community enables students and instructors to practice the deep thinking valued by each instructor and by a traditional liberal arts education while challenging both our and our students’ individual, disciplinary, and rhetorical conventions and beliefs. Using student writing from our course, our assignments from mathematics and composition, and survey evaluation results, we demonstrate how engaging in inquiry-based education provides unconventional …

Early-Season Phenology And Temporal Dynamics Of The Common Asparagus Beetle, Crioceris Asparagi (Coleoptera: Chrysomelidae), In Southern Minnesota, Suzanne J. Wold-Burkness, P. C. Bolin, W. D. Hutchison

The Great Lakes Entomologist

During the years 1991-1994, studies were conducted to determine the early-season phenology and temporal dynamics of Crioceris asparagi (L.) (Co- leoptera: Chrysomelidae) in southern Minnesota asparagus. To document the early-season phenology, asparagus plots were sampled for egg, larval, and adult stages of C. asparagi during the months of May and June. Temporal dynamics of C. asparagi were determined by measuring the diurnal activity of adults and sampling asparagus plots at specific times (7 am, 9 am, 11 am, 1 pm, 3 pm and 5 pm) throughout May and June. We first detected C. asparagi adults in early May and they …

Comparative Biology And Life Tables Of Trichogramma Brassicae And Trichogramma Cacoeciae With Ephestia Kuehniella As Host At Three Constant Temperatures, Nihal Ozder

The Great Lakes Entomologist

Egg parasitoids of the genus Trichogramma (Hymenoptera: Trichogrammatidae) have been successfully utilized for biocontrol of several lepidopteran pests world-wide. The age specific fecundity of Trichogramma brassicae Bezdenko and Trichogramma cacoeciae Marchal using Ephestia kuehniell a Zeller (Lepidoptera: Pyralidae) as host were determined at 20, 26, and 30 °C and 60-70 % R.H. in the laboratory. Both T. cacoeciae and T. brassicae demonstrate high parasitism ability and intrinsic rates of increase on E. kuehniella and had a similar response to increasing temperature.

Seasonal Abundance; Damage; And Comparison Of Different Heights, Orientations, And Directions Of Yellow Sticky Traps For Sampling Of Liriomyza Trifolii (Diptera: Agromyzidae) In Cotton, Ibrahim Gencsoylu

The Great Lakes Entomologist

This study was done to determine the optimum height, orientation, and direction of yellow sticky traps for sampling of Liriomyza trifolii (Burgess) (Diptera: Agromyzidae) in cotton fields. Leaf infestation rates for the whole plants, as well as for each of three plant regions, and number of mines per infested leaf were also determined. Traps were placed at 25 cm above the plant canopy and 30 cm above the ground at two orientations (horizontal and vertical) and two directions (east-to-west and north-to-south) for each height and orientation in Aydin province, Turkey. Horizontally oriented traps captured more flies than vertically oriented traps. …

Effect Of The Cardenolide Digitoxin On Performance Of Gypsy Moth (Lymantria Dispar) (Lepidoptera: Lymantriidae) Caterpillars, David N. Karowe, Victoria Golston

The Great Lakes Entomologist

Despite the central role of cardenolides in the classic milkweed-monarch- predator chemically-mediated multiple trophic level interaction, very few studies have actually demonstrated that cardenolides protect host plants against herbivores. We tested the hypothesis that cardenolides are an effective chemical defense against generalist insect herbivores by feeding fifth instar gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae), larvae artificial diets containing low and high levels of digitoxin, a cardenolide found in leaves of purple foxglove,Digitalis purpurea L. (Scrophulariaceae). Relative to performance of larvae fed the control diet, consumption rate, conversion efficiency, and growth rate were all reduced by at least 60% …

Gerromorpha (Hemiptera: Heteroptera) In Southern Illinois: Species Assemblages And Habitats, Steven J. Taylor, J. E. Mcpherson

The Great Lakes Entomologist

Gerromorphan species assemblages in southern Illinois were studied at 86 sites representing eleven habitat types (pond, lake, swamp, temporary pool, large river, small river, muddy eutrophic permanent stream, clear rocky permanent stream, clear rocky temporary stream, roadside ditch, and spring) from mid-May 1988 through late July 1991. Assemblages varied in size and composition, with the most diverse found in clear rocky permanent streams. Phenograms tended to cluster major habitat types (e.g., ponds, lakes) based on taxon presence/absence and to cluster the more commonly co-occuring species based on their presence/absence at collection sites. These phenograms indicated the presence of natural guilds …

Perspectives And Researcher Experiences Of Undergraduate Research, Steven C. Goetz, Matthew J. Romero, Michael F. Robertson

Journal of Applied Sciences and Arts

Extracurricular undergraduate research seems to improve student success in academic programs, but little research has been conducted in aviation settings to support this phenomenon.

This study aims to address the gap in the body of research by investigating the experiences of aviation students who have participated in extracurricular research at the undergraduate level. This case study, conducted within a large aviation program at a mid-sized Midwestern university, qualitatively examines the perceptions and experiences of these students.

Comparison Of New Metrics For Assessment Of Risks Of Occupational Noise, Wisam Al-Dayyeni, Jun Qin

Journal of Applied Sciences and Arts

Noise induced hearing loss (NIHL) is one of the most common occupational related health problems worldwide. Exposure to excessive noise is the major avoidable cause of permanent hearing loss. The conventional metrics for noise evaluation cannot accurately assess the exposure risks to high-level complex noise, which commonly occurs in many industrial and military fields. Recently, we have developed two advanced models, an adaptive weighting (F-weighting) and a complex velocity level (CVL) auditory fatigue model, to evaluate the risks of occupational noise. In this study, we compared performances of five noise assessment metrics, including F-weighted sound pressure level (SPL) LFeq, CVL …
