Epizootic Shell Disease in Homarus americanus
American lobster populations along the northeastern U.S. coast have been experiencing increased prevalence of Epizootic Shell Disease (ESD) over the past two decades. Several reports have correlated this increase with warmer water temperatures. My thesis examined the distribution of diseased lobsters surrounding Millstone Nuclear Power Station (MPS) in Long Island Sound. Lobsters in this area have seen a rise in Epizootic Shell Disease (ESD) that parallels the broader trends. To determine if the thermal plume from MPS had a local effect on ESD prevalence, the spatial distribution of diseased lobsters was analyzed at three …

Twenty-Five Years Of Change In Spruce Grouse Occupancy At Their Southern Range Margin In Maine, Usa, Christopher J. Gilbert
Honors College
Species at their southern range margin are often dispersed throughout fragmented populations where they experience less optimum conditions compared to their central range. Spruce Grouse (Falcipennis canadensis) are boreal forest obligates distributed throughout the Northern United States and Canada and reach their southeastern range extent in Maine. I resurveyed 18 Black Spruce (Picea mariana) – Tamarack (Larix laricina) stands on Mount Desert Island, Maine, to observe changes in Spruce Grouse occupancy and abundance between the early 1990s (Whitcomb et al. 1996) and present day.

Assessing The Impacts Of Commercial Clearcut On Freshwater Invertebrate Communities, Nicholas J. Kovalik
Assessing The Impacts Of Commercial Clearcut On Freshwater Invertebrate Communities, Nicholas J. Kovalik
Honors College
Forest harvesting can impact the environment in many ways, one of which is causing a loss of subsidies and increased light intensity to freshwater ecosystems. This can have a major impact on freshwater invertebrate communities that may rely on subsidies to survive. In this study, I tested two effects of commercial clearcut, changes in light availability and detrital resources, on freshwater invertebrate communities. Cattle tanks containing freshwater invertebrates were given detritus from two different plots: one which underwent commercial clearcut over 50 years ago, and one which underwent commercial clearcut 2 years ago. Tanks were also placed in two areas …

Estimating Ecosystem Services From Harvested And Unharvested Ascophyllum Nodosum On The Maine Coast, Ashley E. Sarra
Honors College
Ascophyllum nodosum, better known as rockweed, is a commercially important, harvested intertidal brown alga species common in coastal Maine. Rockweed sea vegetable harvesting is a lucrative wild harvest fishery, that has also proved to be socially contentious and whose future management is uncertain. A. nodosum is an intertidal macroalgal species that may also be impacted by sea level rise. Through a combination of biomass estimation, newspaper analysis, and interview data collection, this project seeks to (a) develop a typology of ecological services of A. nodosum in harvested and unharvested areas in the state of Maine; and (b) assess the …
Effect Of Primary Care Follow Up On Hospital Readmissions, Meredith Roderka
Effect Of Primary Care Follow Up On Hospital Readmissions, Meredith Roderka
Honors College
Hospital readmission rates are costly; nearly 1 in 5 hospital patients covered by Medicare are readmitted to the hospital within 30 days of discharge, accounting for $15 billion a year in health care spending (Jencks et al., 2009). The emergency department (ED) is the biggest cost driver for hospital readmissions. The research conducted implemented new protocols with an ED-based research study team that came in at the time of the patient discharge and assist with the transition of care for the patient, scheduling next day follow-ups with their Primary Care Provider. Analysis of this data will include readmission rates for …
Does Drought Affect Reproduction In The Saltmarsh Sparrow (Ammodramus Caudacutus)?, Valerie K. Watson
Does Drought Affect Reproduction In The Saltmarsh Sparrow (Ammodramus Caudacutus)?, Valerie K. Watson
Honors College
The Saltmarsh Sparrow (Ammodramus caudacutus) is experiencing steep population declines, with extinction likely within the next few decades. Sea-level rise has been identified as a major threat to the species, but little has been done to examine the effects of other aspects of climate change on Saltmarsh Sparrow populations. In this study, I examine whether drought affects reproductive success in the Saltmarsh Sparrow. I use nest- and chick-monitoring data collected over five years across the northern half of the species range to test whether drought conditions affect four metrics of reproductive success in these birds: hatch rate, clutch …

Wildlife Use Of Vernal Pools In An Urbanizing Landscape With A Focus On Population Vitality Of Vernal Pool-Breeding Amphibians, Carly Eakin
Electronic Theses and Dissertations
Vernal pools in the northeastern United States provide essential habitat for pool-breeding amphibians and provide resources for other forest-dwelling wildlife. These pools and pool-breeding amphibians in particular are threatened by land conversion associated with urbanization and urban-associated factors. The responses of these amphibians and of birds and mammals using vernal pools to intermediate levels of urban development are largely unknown. I used field observations and lab experiments to study the amphibians, birds, and mammals associated with vernal pools along an urban development gradient in greater Bangor, Maine.
In Chapter 1, I examined bird and mammal use and assemblage composition at …

Strategies For Reducing Moisture Content In Forest Residues At The Harvest Site, Anil Raj Kizha, H-S Han, J. Paulson, A. Koirala
Strategies For Reducing Moisture Content In Forest Residues At The Harvest Site, Anil Raj Kizha, H-S Han, J. Paulson, A. Koirala
Forest Resources Faculty Scholarship
The moisture content (MC) of biomass derived from forest residues can pose a challenge to biomass utilization. It plays a significant role in determining the cost of transportation and subsequent market price. Additionally, emerging biomass conversion technologies, such as gasification, torrefaction, and briquetting, have very narrow specifications for the MC (e.g., <15%) in their feedstocks. The goal of this study was to develop strategies for reducing moisture content by evaluating different arrangement patterns of forest residues and its effect on MC reduction at the harvest site. The study compared four different arrangement patterns including criss-cross, teepees, traditional piling (processor piled), and scattered residues in three different timber harvest units in northern California. Two of the arrangement patterns (criss-cross and processor piled) were also covered with a plastic cover. Samples were collected from each treatment using a transect method and were recorded for 12 months. There was an overall drop of MC from 52% (freshly cut) to 12% between all arrangements over the study period. The cost of construction per pile, averaged $37, $41, and $48 for teepees, criss-cross, and processor piles, respectively. Even though, there was no significant difference in MC reduction between piles (except scattered), each pile arrangement of forest residues directly affected biomass feedstock operations, logistics, and costs.
