Insects Associated With Butternut And Butternut Canker In Minnesota And Wisconsin, Steven A. Katovich, Michael E. Ostry

The Great Lakes Entomologist

Butternut, Juglans cinerea, is being killed throughout its native range in North America by the fungus Sirococcus clavigignenti-juglandacearum. In addition to rain splashed spores, it is thought that the fungus may have spread over long distances to infect widely scattered butternut by insect vectors During surveys in 1995 and 1996 we found several insect species in close association with diseased butternut trees, and spores of S. clavigignenti-juglandacearum were isolated in pure culture from the bodies of some of these insects. Potential insect vectors were species in the coleopteran genera Eubulus (Curculionidae), Laemophlaeus (Laemophloeidae), and Glischrochilus (Nitidulidae). Because several …

Burying Beetles (Coleoptera: Silphidae) Of The Apostle Islands, Wisconsin: Species Diversity, Population Density And Body Size, Stephen T. Trumbo, Shelly Thomas

The Great Lakes Entomologist

Over 2400 burying beetles, representing six species (Nicrophorus defodiens, N. sayi, N orbicollis, N. tomentosus, N vespilloides, and N. pustulatus), were trapped from 27 June to 4 August, 1996 at nine study sites (3 small islands, 3 large islands, and 3 mainland locations) centered around the Apostle Islands National Lakeshore in northern Wisconsin. Species diversity was greatest on the mainland and least on the smallest islands « 600 ha). Nicrophorus defodiens, the smallest of the six species, was marginally overrepresented on the smallest islands. We hypothesize that this occurred because N. defodiens can maintain a larger …

Observations Of First Occurrence And Severity Of Potato Leafhopper, Empoasca Fabae (Harris), (Homoptera: Cicadellidae) In The North Central And Eastern United States., K. M. Maredia, M. E. Whalon, S. H. Gage, M. J. Kaeb

The Great Lakes Entomologist

This paper presents available data on the first occurrence dates and the damage severity of the potato leafhopper in the north central and north eastern United States collected during the past 47 years (1951-1997). The data were collected from a variety of sources including: potato leafhopper literature review; published reports; pest alerts; pest surveys; and delphi surveys. First occurrence and severity data show that the arrival time of potato leafhopper and subsequent damage severity varies substantially from year to year. A correlation analysis between date of first occurrence and severity of damage for Michigan, Minnesota, Wisconsin, the north central region …

Density-Dependent And -Independent Behaviors Of The Adult Karner Blue (Lycaeides Melissa Samuelis) (Lepidoptera: Lycaenidae), Ann B. Swengel, Scott R. Swengel

The Great Lakes Entomologist

At 146 pine-oak barrens in central and northwestern Wisconsin USA during 1988-96, 3973 Karner blues (Lycaeides melissa samuelis Nabokov) were found in 95.4 hr of transect surveys during spring and 6896 individuals in 134.8 hr during summer. Of these, 9346 (86%) individuals were first observed copulating, feeding, flushing, flying, or involved in a non-copulatory intraspecific interaction. All these behaviors except copulation showed density-independent influences; all these behaviors also had density-dependent influences. The most frequently significant density-independent variables affecting occurrence of these behaviors were temperature, brood (spring vs. summer), and crepuscularity (time since noon). Male (rather than female or overall) …

Faunal Composition, Wing Polymorphism And Seasonal Abundance Of Some Flea Beetles (Coleoptera: Chrysomelidae) In Southern Quebec (Canada), Claire Levesque, Gilles-Yvon Levesque

The Great Lakes Entomologist

Chrysomelidae (51 taxa) were collected with flight intercept traps from May through October during 1987-1989, in four sites near a raspberry plantation in southern Quebec. More species and individuals of phytophagous flea beetles occurred in two open sites than at a pine woods-raspberry field boundary and in a pine woods. Longitarsus luridus complex, an immigrant taxon in North America, represented 58% of all captures in the two open sites where both Ranunculus acris and Plantago spp. are its main host plants; this species and Longitarsus rubiginosus were almost exclusively represented by jumping apterous adults in pans of flight intercept traps. …

Butterfly (Lepidoptera: Lycaenidae, Nymphalidae, And Satyridae) Faunas Of Three Peatland Habitat Types In The Lake Superior Drainage Basin Of Wisconsin, Jeffrey C. Nekola

The Great Lakes Entomologist

The butterflies which complete their entire life cycle within peatland habitats were documented in the Lake Superior drainage basin of northwestern Wisconsin. Seventy peatlands were inventoried over the course of the 1996 growing season, and were classified as either muskeg, kettlehole, or coastal sites. Muskeg peatlands were of similar elevation to the surrounding uplands, possessed drier and more nutrient-poor substrates, and were typically larger than other peatland types. Kettlehole peatlands were wetter and had floating Sphagnum mats which fringed lake margins or were in depressions much lower than the surrounding uplands. Coastal peatlands were located in estuaries along the Lake …

New Distribution Records Of Somatochlora Hineana (Odonata: Corduliidae), Wayne P. Steffens

The Great Lakes Entomologist

New records for Somatochlora hineana in Michigan are reported, extending the known distribution of the species by nearly 200 km to the northeast. Habitats are rich fens with shallow creeks, springs, small pools, and marl deposits.

Probable Displacement Of Riffle-Dwelling Invertebrates By The Introduced Rusty Crayfish, Orconectes Rusticus (Decapoda: Cambaridae) In A North-Central Wisconsin Stream, David C. Houghton, Jeffrey J. Dimick, Richard V. Frie

The Great Lakes Entomologist

The rapid northward range expansion of the rusty crayfish, Orconectes rusticus, and its negative effects on Wisconsin lakes have been the subjects of intense study throughout the last fifteen years. In this study, we investigated the possible impact of rusty crayfish on the benthic macroinvertebrate community structure of the Prairie River in north-central Wisconsin. Rusty crayfish and other invertebrates were collected during August and September, 1994, from three sections of the Prairie River. Rusty crayfish relative abundance increased significantly from the upper to middle, and middle to lower sections; and correlated negatively with a significant 77% decrease in total …

A Modification Of The Biotic Index Of Organic Stream Pollution To Remedy Problems And Permit Its Use Throughout The Year, William L. Hilsenhoff

The Great Lakes Entomologist

The biotic index of the arthropod fauna of streams is modified by limiting to ten the number of individuals in each taxon used in its calculation. This reduces detrimental effects on the index of certain fairly tolerant taxa in clean streams, effects of a few tolerant taxa in somewhat polluted streams, and the effect of our inability to identify larvae in some insect genera to species. It also greatly reduces seasonal variability, allowing use of the biotic index throughout the year with only a minimal decrease in the sensitivity of the index during the summer months. The EPT index was …

No Observable Relative Age Effects In Professional Surfers: A Constraints-Based Evaluation, Michael Redd, David Fukuda, Kyle Beyer, Leonardo Oliveira

International Journal of Exercise Science

International Journal of Exercise Science 11(6): 355-363, 2018. With the recent inclusion of surfing in the 2020 Olympic Games in Japan, there will be a number of surfing athletes vying for one of the twenty total available spots for their respective gender. The purpose was to evaluate relative age effects (RAEs) in surfing with consideration for specific developmental constraints. Elite competitive male surfers (n = 1590) were examined by birth month and subcategorized by competitive level, age groups, and geographical regions. The observed quarterly distribution was not significantly different (using c²; p>0.05) from expected for the overall …

Mitochondrial And Nuclear Sequences For Phylogenetic Analysis Of Three Cephalopod Species, Northern Gulf Of Mexico, May 2015 To May 2017, Amanda Sosnowki

DEEPEND Datasets

The midwater column contains a wide diversity of cephalopods in the northern Gulf of Mexico. DNA sequence data (barcodes) have become a key tool to discover hidden biodiversity. We generated mitochondrial DNA barcode datasets based on the Cytochrome c oxidase I (COI), 16s, and 28s genes from cephalopods. These data were analyzed using phylogenetic methods to examine possible connectivity of 3 species (Vampyroteuthis infernalis, Pyroteuthis margaritifera, and Cranchia scabra) between two basins, the Gulf of Mexico and the area surrounding Bear Seamount in the northwestern Atlantic Ocean. These datasets were generated from cephalopods collected in the northern Gulf of Mexico …

The Relationship Between Observational Scale And Explained Variance In Benthic Communities, Alison M. Flanagan, Roger D. Flood, Michael G. Frisk, Corey D. Garza, Glenn R. Lopez, Nicole P. Maher, Robert M. Cerrato

School of Natural Sciences Faculty Publications and Presentations

This study addresses the impact of spatial scale on explaining variance in benthic communities. In particular, the analysis estimated the fraction of community variation that occurred at a spatial scale smaller than the sampling interval (i.e., the geographic distance between samples). This estimate is important because it sets a limit on the amount of community variation that can be explained based on the spatial configuration of a study area and sampling design. Six benthic data sets were examined that consisted of faunal abundances, common environmental variables (water depth, grain size, and surficial percent cover), and sonar backscatter treated as a …

Winner-Take-All In A Phase Oscillator System With Adaptation, O Burylko, Y Kazanovich, R Borisyuk

School of Engineering, Computing and Mathematics

We consider a system of generalized phase oscillators with a central element and radial connections. In contrast to conventional phase oscillators of the Kuramoto type, the dynamic variables in our system include not only the phase of each oscillator but also the natural frequency of the central oscillator, and the connection strengths from the peripheral oscillators to the central oscillator. With appropriate parameter values the system demonstrates winner-take-all behavior in terms of the competition between peripheral oscillators for the synchronization with the central oscillator. Conditions for the winner-take-all regime are derived for stationary and non-stationary types of system dynamics. Bifurcation …

Cooperative Standing-Horizontalstanding Reentrant Transition For Numerous Solid Particles Under External Vibration, Satoshi Takatori, Hikari Baba, Takatoshi Ichino, Chwen-Yang Shew, Kenichi Yoshikawa

Publications and Research

We report the collective behavior of numerous plastic bolt-like particles exhibiting one of two distinct states, either standing stationary or horizontal accompanied by tumbling motion, when placed on a horizontal plate undergoing sinusoidal vertical vibration. Experimentally, we prepared an initial state in which all of the particles were standing except for a single particle that was placed at the center of the plate. Under continuous vertical vibration, the initially horizontal particle triggers neighboring particles to fall over into a horizontal state through tumbling-induced collision, and this effect gradually spreads to all of the particles, i.e., the number of horizontal particles …

Distribution Of Gymnosperms In Pir Lasura National Park, Kishwar Sultana, Afsar Mian, Asad Ghufran, Sabiha Shamim

Journal of Bioresource Management

Survey carried out in June-July 2009 recorded a minimum of 159 plant species with 48 species of trees. Out of these only two species are of gymnosperms; Pinus roxburghii and Pinus wallichiana. One species of trees, Pinus roxburghii is widely distributed. It is present in all communities, and can be found in different combinations with different other species. Both of these species have ethnobotanical value and are used by local population for different purposes.

Examination Of Clock And Adcyap1 Gene Variation In A Neotropical Migratory Passerine, Andrea Contina, Eli S. Bridge, Jeremy D. Ross, J. Ryan Shipley, Jeffrey F. Kelly

School of Integrative Biological & Chemical Sciences Faculty Publications

Complex behavioral traits, such as those making up a migratory phenotype, are regulated by multiple environmental factors and multiple genes. We investigated possible relationships between microsatellite variation at two candidate genes implicated in the control of migratory behavior, Clock and Adcyap1, and several aspects of migratory life-history and evolutionary divergence in the Painted Bunting (Passerina ciris), a species that shows wide variation in migratory and molting strategies across a disjunct distribution. We focused on Clock and Adcyap1 microsatellite variation across three Painted Bunting populations in Oklahoma, Louisiana, and North Carolina, and for the Oklahoma breeding population we …

Spatial Delineation Of Corrosion Zones For Metal Culverts Based On Coastal Louisiana Soil Characteristics, Sanjay Tewari, Francis Manning

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Corrosion of metal pipes used as culverts is a problem that affect many agencies directly involved in designing and maintaining these culverts. The corrosive environment of soil types found in a region could vary in a significant way (mildly corrosive to extremely corrosive) based on soil characteristics. Environmental conditions such as high water table, acidity and presence of various salts could make a soil corrosive to metal pipes. In this article, authors have applied a methodology of processing readily available soil data such as spatial distribution of soil types and soil characteristics (e.g. pH and conductivity) in delineating spatial corrosion …

Maxwell H. Gluck Equine Research Center Faculty Publications

Equine influenza, caused by the H3N8 subtype, is a highly contagious respiratory disease affecting equid populations worldwide and has led to serious epidemics and transboundary pandemics. This study describes the phylogenetic characterization and replication kinetics of recently-isolated H3N8 virus from a nasal swab obtained from a sporadic case of natural infection in an unvaccinated horse from Montana, USA. The nasal swab tested positive for equine influenza by Real-Time Quantitative Reverse Transcription Polymerase Chain Reaction (RT-PCR). Further, the whole genome sequencing of the virus confirmed that it was the H3N8 subtype and was designated as A/equine/Montana/9564-1/2015 (H3N8). A BLASTn search revealed …

The Slippery Slope Of "Unique", Daniel J. Julius

Journal of Collective Bargaining in the Academy

That higher education may not be considered unique by various courts, labor boards, arbitrators, law firms, and others who facilitate (control) the labor relations process is a decidedly unpopular notion among many academic leaders, faculty, and others. I would argue that universities are organizations providing important individual and societal outcomes which can be measured, but may not be unique for the purposes of labor relations.

Indiana Record For Onthophagus Taurus (Coleoptera: Scarabaeidae): Northwestward Range Extension, Adrienne E. Smith

The Great Lakes Entomologist

(excerpt)

The scarab, Onthophagus taurus Schreber, was introduced from Europe, although the details of its introduction are unknown (Fincher and Woodruff 1975). It was first collected in the Florida panhandle in 1971 (Fincher and Woodruff 1975); by 1974 its range had extended into Georgia, and by 1980 it had reached South and North Carolina (Fincher et al. 1983).
