Sources Of Variability In Agronomic Weed Seed Predation: Time, Space, Habitat, And Hyperpredation, Sonja K. Birthisel

Electronic Theses and Dissertations

Weed seed predation is an ecosystem service that benefits farmers by decreasing seedbank inputs, thereby reducing weed pressure in subsequent growing seasons. Seed predation can be considerable, but is highly variable. Sources of variability may include time, space, habitat, and trophic interactions such as hyperpredation. Two experiments were conducted to measure the impacts of these sources of variability on weed seed predation rates in Maine mixed vegetable agroecosystems.

Chapter One of this thesis describes a series of landscape-level field experiments conducted to quantify the effects of time, space, and habitat on seed predation rates. Seed assays, with and without vertebrate …

The Effect Of Wild Blueberry Consumption On The Inflammatory Response, Oxidative Stress And Dna Damage Associated With Exercise, Taylor K. Bloedon

Electronic Theses and Dissertations

At all levels of intensity and duration, exercise is known to cause an increase in the generation of reactive oxygen species (ROS). When derivatives of oxygen occur and exist independently with one or more unpaired electrons they are known as “free radicals” (Halliwell and Gutteridge 2007). Since atoms possess electrons that are usually associated in pairs, free radicals have the potential to act negatively in the body. Reactive oxygen species refer to oxygen-centered radicals as well as nonradical but reactive derivatives of oxygen (Halliwell and Gutteridge 2007). When ROS are created in excess, resulting in the disruption of the pro-oxidant/antioxidant …

A Study Of The Social And Economic Capacity Of Eastern Maine Fishing Communities: How Can Small-Scale Fishing Communities Participate In Catch Share Programs?, Teresa R. Johnson, Kevin Athearn

University of Maine Office of Research Administration: Grant Reports

This study aimed to assess the degree to which small-scale, fishery-dependent communities in eastern Maine can participate in the catch share system for New England groundfish. Catch share programs can take on a variety of forms, including: harvesting cooperatives, individual quotas, individual transferable quotas, or territorial user fishing rights (Holland and Wiersma 2010). In New England the regional Fishery Management Council implemented a catch share program beginning in 2010, known as sectors, where portions of the total allowable catch have been allocated to groups of fishermen. As managers continue to develop catch shares, and stocks hopefully rebuild, it is critical …

Cnh: Collaborative Research: Direct And Indirect Coupling Of Fisheries Through Economic, Regulatory, Environmental, And Ecological Linkages, Andrew J. Pershing, Yong Chen, Jeffrey Runge

University of Maine Office of Research Administration: Grant Reports

The productivity and resilience of fisheries are subject to a multitude of dynamic and interrelated influences that arise from complex coupling of fish populations with the natural and human systems of which they are a part. With few exceptions, fisheries currently are managed independently, ignoring important natural and human linkages among them. The biological productivity, sustainability, and consequently human benefits of complex fishery systems may be substantially increased if these linkages are better understood and if this understanding is applied to management. The American lobster (Homarus americanus), Atlantic herring (Clupea harengus) and Northeast multispecies groundfish fisheries in the Gulf of …

Revsys: Systematics Of Amelanchier (Rosaceae), Christopher S. Campbell

University of Maine Office of Research Administration: Grant Reports

Amelanchier contains about 20 species of trees and shrubs of the North Temperate Zone. These plants bear attractive flowers, their fruits are important to wildlife, and they are valued horticulturally. Shadbushes and serviceberries, as these plants are commonly called, are native to every state of the United States except Hawaii. It has been a challenge to define the species of Amelanchier because hybridization is frequent, and novel kinds of plants created by hybridization can be widely dispersed. Some forms of shadbushes are easy to distinguish while others differ from one another in minute ways. The goal of this research is …

Is Pressure Stressful? The Impact Of Pressure On The Stress Response And Category Learning, Shannon L. Mccoy, Steven B. Hutchinson, Lauren Hawthorne, Brandon J. Cosley, Shawn W. Ell

Psychology Faculty Scholarship

We examine the basic question of whether pressure is stressful. We propose that when examining the role of stress or pressure in cognitive performance it is important to consider the type of pressure, the stress response, and the aspect of cognition assessed. In Experiment 1, outcome pressure was not experienced as stressful but did lead to impaired performance on a rule-based (RB) category learning task and not a more procedural information-integration (II) task. In Experiment 2, the addition of monitoring pressure resulted in a modest stress response to combined pressure and impairment on both tasks. Across experiments, higher stress appraisals …

Collaborative Research: Globec Pan-Regional Synthesis: End-To-End Energy Budgets In Us-Globec Regions, Andrew C. Thomas

University of Maine Office of Research Administration: Grant Reports

The research addresses the overarching question: are marine food webs leading to fisheries controlled from the top-down, the bottom up, or a combination of the two? To address this question we will (1) compare end-to-end energy budgets of the 4 US-GLOBEC study regions in the context of top-down v. bottom-up forcing, (2) assess the skills of the regional models in capturing basic material fluxes, (3) extract diagnostics from the regional models that will be used to evaluate the effects of climate change and fishing pressure across GLOBEC regions and (4) develop quantitative methods to compare the diagnostics. The major successes …

Mp762: Harvesting Equipment Cycle Time And Productivity Guide For Logging Operations In Maine, Patrick Hiesl, Jeffrey G. Benjamin

Miscellaneous Publications

This guide provides cycle time and productivity information for harvesting equipment commonly used in Maine’s logging industry for partial harvests. Data were collected in terms of time consumption per work task. With these data, cycle time equations were developed. Productivity functions were developed using tree volumes. It is important to remember that productivity may vary from stand to stand due to differences in tree volume at the site level. Cycle time functions are independent of tree volume and will give fairly accurate predictions of time consumption per machine.

Production Ecology And Stand Dynamics Of Young Acadian Forest Stands In Response To Silvicultural Intensity And Compositional Objectives, Andrew S. Nelson

Electronic Theses and Dissertations

Early successional stands are common across the Acadian forests of eastern Canada and the Northeastern US. However, productivity and dynamics of these stands, as well as the underlying mechanisms influencing these processes, under different management scenarios are poorly understood. To address this need, I used a factorial experiment that controlled silvicultural intensity and species composition to quantify the effects of varying treatments on early stand dynamics, and the physiological and morphological factors influencing tree performance . Specifically, I studied: 1) species differences in aboveground allometrics, 2) light capture, light-use efficiency (LUE; growth/light capture), and foliar carbon isotope composition (δ13C) of …

Characterization Of Phycoerythrin Physiology In Low-Light Adapted Prochlorococcus Ecotypes, Kathryn H. Roache-Johnson

Electronic Theses and Dissertations

The marine cyanobacteria Prochlorococcus and Synechococcus are the most abundant phototrophs in the oceans. They cohabit the oligotrophic ocean and thus have coevolved together, yet they have distinctly different methods for harvesting light. Synechococcus, like other cyanobacteria, possess phycobilisomes with various combinations of phycobiliproteins to capture wavelengths of light not otherwise available to chlorophyll. Prochlorococcus lack phycobilisomes and use divinyl chlorophyll b (Chl b2) as their primary accessory pigment to divinyl chlorophyll a (Chl a2) to capture light energy. In addition to the divinyl chlorophylls, Prochlorococcus has genes associated with the phycobiliprotein phycoerythrin (PE), the role of which is still …

Collaborative Research: Land-Use Practices And Persistence Of Amphibian Populations, Malcolm L. Hunter Jr.

University of Maine Office of Research Administration: Grant Reports

Over the past 200 years, conversion of land for agricultural use, industrial development, and urban sprawl has drastically reduced natural habitat for many species and is considered the most serious threat to biological diversity. Fragmentation divides once continuous natural habitats into smaller pieces that are often separated by areas unsuitable to sustain viable populations. The goal of the proposed research is to understand how important local population and metapopulation processes are altered by fragmentation of natural habitats in a model system of pond-breeding amphibians. The primary objectives of the proposed study are to experimentally compare demographic and behavioral responses of …

Targeted Training Of The Decision Rule Benefits Rule-Guided Behavior In Parkinson’S Disease, Shawn W. Ell

Psychology Faculty Scholarship

The impact of Parkinson’s disease (PD) on rule-guided behavior has received considerable attention in cognitive neuroscience. The majority of research has used PD as a model of dysfunction in fronto-striatal networks, but very few attempts have been made to investigate the possibility of adapting common experimental techniques in an effort to identify the conditions that are most likely to facilitate successful performance. The present study investigated a targeted training paradigm designed to facilitate rule learning and application using rule-based categorization as a model task. Participants received targeted training in which there was no selective-attention demand (i.e., stimuli varied along a …

Mr445: Maine Wild Blueberry Growers: A 2010 Economic And Sociological Analysis Of A Traditional Downeast Crop In Transition, Anya Rose, Francis A. Drummond, David E. Yarborough, Eric Asare

Miscellaneous Reports

An extensive mail survey of Maine wild blueberry growers was conducted in spring 2010, the first extensive sur­vey of growers in almost three decades (1974). The objective of the survey was to quantify the diversity of growers’ philosophies, management practices, and perspectives on their priorities in producing blueberries. We also wanted to identify the sources of new information upon which growers rely. Our results are based on 100 responses from a grower population of 353. We asked growers to place themselves into one of four categories representing distinct ap­proaches to management: conventional (12%), integrated pest management (IPM, 65%), organic (13%), …

Productivity Standards For Whole-Tree And Cut-To-Length Harvesting Systems In Maine, Patrick Hiesl

Electronic Theses and Dissertations

The forest industry is a highly cost intensive business and therefore effective management is necessary. Information about productivity and time consumption of harvesting equipment in a variety of stand and site conditions can help operation managers to be efficient. In the state of Maine there have not been any productivity related publications within the past 25 years. Due to this lack of information and the need of information of productivity, especially in small diameter stands, the presented research developed. The focus of this study is on whole-tree harvesting systems including feller-buncher, grapple skidder and stroke delimber, as well as cut-to-length …

Foraging Behavior Of Eastern Gray Squirrels On The University Of Maine Campus, Aimee Young

Honors College

The goal of this study was to observe the foraging behavior of Eastern Gray Squirrels (Sciurus carolinensis) on the University of Maine campus. The study tested whether squirrels in a more urban setting followed the optimal foraging theory, or if rarity of a food type played a greater factor in food selection. The study also examined whether urban squirrel behavior mimicked that of wild squirrels when presented with a food type uncommon on campus, but common in other parts of Maine, specifically the acorns of the white oak tree (Quercus alba). In three different areas on the campus, squirrels were …
