Heller, Sarah Jandricic, M D. Marks, Yesuf Mohammed, William L. Perry, Winthrop B. Phippen, Lucas M. Roberts, Samantha Wells, Tad L. Wesley, Julia Zhang

The Great Lakes Entomologist

Pennycress is being developed in the Midwestern USA as a new oilseed crop that provides numerous ecosystem services. These services include being an early spring source of pollen and nectar for flower-visiting insects. Most past research on pennycress flower visitors used wild genotypes of pennycress. All wild genotypes have seed coats that are black, which occurs because of high levels of proanthocyanadins (PACs). Concentrations of PACs are minimal in newly developed genotypes with yellow-colored seed coats. However, little is known regarding flower abundance and timing nor insect visitation preferences for black-seeded genotypes (BSG) or yellow-seeded genotypes (YSG) of pennycress. Flower …

Compromised Communication: The Threat Of Disinformation To Rational Bargaining, Marydalia Jimenez

Binghamton University Undergraduate Journal

This paper integrates theories of disinformation with the “Bargaining Model,” a theory in political science that explains why actors choose to go to war even though they might achieve their aims more efficiently through bargaining. As a case study, the paper takes a disinformation campaign during the Cold War and Russia’s war in Ukraine (2014-present) to provide evidence for the way that disinformation undermines international dialogue and bases the status quo in unreal conditions, thereby making the bargaining process irrational and diminishing the opportunity for resolution.

The Effect Of Temperature And Vegetative Substrate On The Short-Distance Dispersal Behavior Of An Invasive Weevil (Coleoptera: Curculionidae) To A Protected Dune Thistle, Alyssa S. Hakes, Tina Czaplinska, Monica Paniagua-Montoya

The Great Lakes Entomologist

The invasion of a seed-eating weevil, Larinus carlinae (Olivier, 1807) poses a threat to the persistence of native Pitcher's thistle (Cirsium pitcheri), a federally-threatened plant in sand dune communities of the western Great Lakes. At Whitefish Dunes (Sturgeon Bay, WI. USA), seed predation by weevils is higher for thistles surrounded by native marram grass (Ammophila breviligulata) than for those located in sandy habitats. In this study, we observed how the local abiotic and biotic environment affects the short-distance dispersal behavior of L. carlinae. Weevils were captured on site and individually released on the sand approximately …

Occurrence Of Spotted Wing Drosophila (Drosophila Suzukii) In Wild Berries In Forested Areas Of Marquette And Keweenaw Counties, Upper Peninsula Of Michigan, Alexis M. Shatrau, Erika I. Hersch-Green

The Great Lakes Entomologist

Spotted-wing Drosophila (SWD, Drosophila suzukii Matsumura, Diptera: Drosophilidae) is an invasive fly that targets unripe soft-fruits causing premature ripening, dehiscence, and rotting. While the presence of SWD in agricultural systems is well-documented, much less is known about the host range of SWD in wild areas, especially in more northern latitudes where colder temperatures and short summers are thought to restrict their life-cycles and limit population growth. In 2019 and 2020, we collected wild berries from two counties in the Upper Peninsula of Michigan, with long, cold winters, to determine the prevalence, host range, and seasonal/temporal variation of SWD. We found …

Initial Responses Of Carabidae (Coleoptera) To Intensive Biomass Harvesting And Soil Compaction In Aspen Stands Of The Huron-Manistee National Forest, Oscoda County, Michigan, Robert Haack, Robert E. Acciavatti, Robert L. Davidson, Toby Petrice

The Great Lakes Entomologist

During the 1990s, the United States Forest Service implemented several studies to measure the impacts of organic matter removal and soil compaction on forest productivity in forest ecosystems throughout the country. One site was in northeastern Lower Michigan on the Huron-Manistee National Forest in Oscoda County. This site was dominated by mature quaking aspen (Populus tremuloides Michx.) and bigtooth aspen (P. grandidentata Michx.) growing on sandy loam soils. The three organic-matter removal treatments at the site included: 1. stem-only harvesting (SOH); 2. whole-tree harvesting (WTH); and 3. whole-tree harvesting plus forest floor removal (FFR).

A Randomized Controlled Study Of Heart Rate Variability Biofeedback In An Older Adult Sample, Whitney D. Allen

Theses and Dissertations

Heart rate variability biofeedback (HRVB) is a controlled breathing treatment designed to increase the variation in consecutive heartbeats leading to improved regulation of one's autonomic nervous system thereby improving one's ability to self-regulate and maintain homeostasis. Changes in heart rate variability (HRV) are seen in those of increased age and lower HRV is associated with poorer outcomes (e.g., increased mortality, worse emotional functioning, cardiovascular risk factors). As such, older adults are a group that stands to benefit from HRVB principles. The current randomized control trial was designed to understand the impact of HRVB in an older adult population on resting …

Faculty Publications

Northern hardwood forests have long been assumed to be primarily nitrogen limited, but may often be co-limited by multiple elements. Nutrient limitation can be inferred through responses of foliar and litter chemistry to nutrient addition over time. We compared community-level foliar and litter chemistry and resorption efficiency in a long-term, factorial nitrogen (N) and phosphorus (P) fertilization study across 10 forest stands at three sites in New Hampshire, where N and P were added annually. We measured N, P, calcium (Ca), magnesium (Mg), and potassium (K) in foliage from codominant trees and in fresh litter in 2008–2010 (pretreatment) and again …
