Leaf Mining Insects and Their Parasitoids in the Old-Growth Forest of the Huron Mountains
Leaf mining insects in an old-growth forest along the south central shore of Lake Superior in Michigan are documented. We present the results of a 13-year survey of leaf mining species, larval hosts, seasonal occurrence, and parasitoids, as well as report biological observations. Representative larvae, mines, adults, and parasitoids were preserved. Among the larval host associations, 15 are reported as new. Additionally, 42 parasitoid taxa were identified resulting in six first reports from the New World and 32 new host associations. Two undescribed species (Gelechiidae and Figitidae) discovered through this research were described in earlier publications
Groundwater Hydrology of a Population of Lindera melissifolia in Arkansas
Groundwater hydrology was monitored from October through August in and around a bottomland forest pond containing Lindera melissifolia, pondberry. The study site exhibited a series of low ancient dunes and depressions, with seasonal ponds in the depressions. Ponds showed no surface inlets or outlets. Shallow wells were made and soil cores removed along a transect from the top of one dune across the pond to a lower dune. Piezometers were installed in the wells and groundwater levels monitored. Soil core samples were analyzed to determine particle size distribution at soil profile positions selected during field analysis. It was shown that a subsurface hydrologic gradient exists between surrounding dune slopes and the pond bottom, delivering groundwater to the pond during the season when precipitation exceeds evapotranspiration. The hydrologic gradient was shown to be substrate-dependent

The Endoscopic Approach to the Diagnosis of Upper Gastrointestinal Bleeding
Fifty-nine consecutive patients who were bleeding from the upper gastrointestinal tract were examined endoscopically with fiberoptic instruments. The site and nature of the bleeding were identified in 84% of the patients without significant morbidity or mortality. Endoscopic examination of the esophagus, stomach and duodenum in the bleeding patient should be done within 12 to 24 hours after hospital admission and before barium study of the upper gastrointestinal tract
Cabin Point Creek Channelization Study : Final Report
In the realm of environmental impact assessment and analysis the effects of a proposed project are most often referred to in the subjunctive sense because of the qualifications and probabilities related to these postulations. Seldom does the opportunity present itself to follow a project to fruitition and beyond to, in fact, determine the validity of the assumptions made in arriving at the potential impacts of a project. Even less often is it possible to monitor a project from prior to construction to several years after the project has been completed to ascertain the exact nature of the projects impacts, compare pre- and post-project conditions and verify with some certainty the predicted impacts. The present study of the channelization of Cabin Point Creek is one such opportunity
Exploring men’s experiences and sense-making of Bipolar Disorder diagnoses and mood management: A photo-elicitation investigation
Objective: Men’s experiences of living with and managing the symptoms associated with Bipolar Disorder are poorly understood. There is also a lack of qualitative studies focused on men’s experiences of Bipolar Disorder despite the clinical importance of this understanding for successfully supporting men to live well and manage mood symptoms. Method: This qualitative study used a photo-elicitation approach to explore how men made sense of managing their mood symptoms when living with Bipolar Disorder. Six participants took photographs representing their experiences of managing their diagnosis and mood symptoms, which formed the basis of in-depth participant-led semi-structured interviews. Results: An Interpretative Phenomenological Analysis identified four themes: (1) ‘managing symptoms: living with the enemy’; (2) ‘we’re not just managing mood episodes’; (3) ‘managing goes beyond a list of strategies’; and (4) ‘medication is a necessary evil’. Common across the sample’s experiences was the importance of accommodating the disruption caused by mood-related triggers and symptoms. Notably, explicit descriptions of masculinity or male identity were absent from the participants’ sense-making. Conclusions: Findings support a clinical focus on promoting idiosyncratic recoveries and living well, focusing on life beyond symptom reduction and relapse prevention, and facilitating ‘sense making’ of men’s Bipolar diagnoses and experiences in practice
