Electronic Theses and Dissertations

The aim was to screen and optimize low-cost lignosulfonates (LST) as legume silage and hay preservatives to decrease losses of DM and nutritive value due to spoilage. In experiment 1, we evaluated the effects of untreated silage (0%), sodium lignosulfonate (NaL) and magnesium lignosulfonate (MgL) applied independently at 0.5, 1, and 1.5 (% w/w, fresh basis) and INO (Pediococcus pentosaceus and Lactobacillus plantarum; 5 and 4 log cfu/fresh alfalfa g, on high moisture alfalfa (Medicago sativa L.) silage nutrient preservation. Data were analyzed as a randomized complete block design (RCBD; 5 blocks) and linear and quadratic polynomial contrasts were used …


Holistic Monitoring Of Maine Sea Lice (Lepeoptheirus Salmonis, Kroyer, 1837) Sensitivities To Therapies: Developing A Novel Assay To Examine Lice Behavior, Kathryn Liberman Dec 2020

Holistic Monitoring Of Maine Sea Lice (Lepeoptheirus Salmonis, Kroyer, 1837) Sensitivities To Therapies: Developing A Novel Assay To Examine Lice Behavior, Kathryn Liberman

Electronic Theses and Dissertations

Sea lice (Lepeoptheirus salmonis) present significant economic and animal welfare challenges to salmon aquaculture globally. Chemical delousing agents are used in many countries, with each nation eventually reporting sea lice developing reduced sensitivities to treatments. While some countries have in place sea lice sensitivity monitoring programs, that is not the case in Maine, USA. Although chemical delousing agents are not currently used in Maine, they have been used in the past and are currently used in neighboring Canadian salmon farms. Different bay management areas (BMAs) were sampled during different seasons to determine if there is a seasonal or spatial component …


Sustainable Production Of Feed For Recirculating Aquaculture Using Black Solider Flies And Microalgae, Patrick Erbland Dec 2020

Sustainable Production Of Feed For Recirculating Aquaculture Using Black Solider Flies And Microalgae, Patrick Erbland

Electronic Theses and Dissertations

The demand for high-quality, nutritious food continues to increase as human populations grow. As wild fisheries are depleted, aquaculture production is growing to meet the demand for seafood. Sustainable alternatives to wild caught fish meal are increasingly valued for aquaculture feed production. Microalgae and insect larvae are both valuable sources of fatty acids in aquaculture feed. Black soldier fly larvae, Hermetia illucens (L.) are used to convert organic waste streams into insect-based animal feeds. We tested their ability to retain alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) from feeding substrates, which has important implications for their use …


Wildlife Rehabilitation Datasets As An Underutilized Resource To Understand Avian Threats, Mortality, And Mitigation Opportunities, Michelle M. Duffy Dec 2020

Wildlife Rehabilitation Datasets As An Underutilized Resource To Understand Avian Threats, Mortality, And Mitigation Opportunities, Michelle M. Duffy

Electronic Theses and Dissertations

Wildlife rehabilitation centers collect large datasets that focus on medical care, yet they also collect information more broadly relevant to wildlife conservation. The goal of this study was to demonstrate the potential for these datasets to be used in conservation science to better understand avian threats, mortality, and mitigation opportunities. We quantified the causes of bird admissions to rehabilitation centers within the Northeast and Midwest United States, the mortality rates during rehabilitation by admission cause, and the proportion of anthropogenic-caused admissions. Additionally, we related human population and development metrics to the number of bird admissions to better understand geographic bias …

Uncertainties And Robustness In Fisheries Stock Assessment And Management: Data Processing, Modeling And Socioeconomic Aspects, Luoliang Xu Nov 2020

Uncertainties And Robustness In Fisheries Stock Assessment And Management: Data Processing, Modeling And Socioeconomic Aspects, Luoliang Xu

Electronic Theses and Dissertations

The main uncertainties that affect the quality of fisheries stock assessment and pose great challenges to fisheries management can stem from a wide range of sources including observation errors associated with model input data, dynamic model process errors, model structure misspecifications, and/or volatile fishery-related socioeconomic environment. Many assessment and management failures are in part attributed to inappropriate consideration of different uncertainties. For many traditional stock assessment models, the observation error is the only source of uncertainty that modelers explicitly deal with. The observation error is usually assumed to be random. The objective functions are formulated by the corresponding distributions (e.g., …

The Synergistic Effects Of Elevated Temperature And Co2 - Induced Ocean Acidification Reduce Cardiac Performance And Increase Disease Susceptibility In Subadult, Female American Lobsters Homarus Americanus H. Milne Edwards, 1837 (Decapoda: Astacidea: Nephropidae) From The Gulf Of Maine, Amalia M. Harrington, Robert Harrington, Heather J. Hamlin, Deborah A. Bouchard

Journal Articles

Increased greenhouse gas emissions have caused rapid ocean warming (OW) and reduced ocean pH via acidification (OA). Both OW and OA will likely impact marine crustaceans, but they are often examined in isolation. We conducted an environmental-stressor experiment to understand how exposure to current summer conditions (16 °C, pH 8.0), OW only (20 °C, pH 8.0), OA only (16 °C, pH 7.6), or both acidification and warming, OAW (20 °C, pH 7.6), differentially influence thermal physiology and immune response of female subadults of the American lobster, Homarus americanus H. Milne Edwards, 1837. Following a 42 d exposure, cardiac performance was …

Movement And Survival Of Atlantic Salmon Smolts In The Penobscot River, Maine, Alejandro Molina Moctezuma Aug 2020

Movement And Survival Of Atlantic Salmon Smolts In The Penobscot River, Maine, Alejandro Molina Moctezuma

Electronic Theses and Dissertations

The Penobscot River system hosts the largest population of endangered Atlantic salmon Salmo salar in the United States. However, total adult returns in this river remain low. Historically low numbers led to listing of the distinct population segment (DPS) in 2000, and the Penobscot River population was included in the DPS in 2009. Reducing mortality in all life stages is crucial for the recovery of Atlantic salmon populations. One of the life stages associated to high mortality is the juvenile stage (smolts), in which individuals migrate downstream towards the estuary. During this migration smolts face a series of new conditions …

Assessing Lipid Content In Migrating Alewife, Anthony Zenga May 2020

Assessing Lipid Content In Migrating Alewife, Anthony Zenga

Honors College

Alewife are a commercially, economically, and ecologically important fish, that expend large amounts of energy during their long migrations to spawning habitat. This energy demand can influence an individual’s chances of surviving and reproducing successfully. To understand how energy use may affect fitness, we captured alewife from the Souadabscook Stream over the course of their spawning migration. Fifty fish were sampled each week from May 12th to June 10th 2019. The lipid content of each individual was measured by using i) a Distell Fatmeter and ii) gravimetric analysis by measuring muscle moisture as an indirect method to assess lipid content. …


The Role Of Personality In Large Nut Dispersal By Sciurus Carolinensis And Its Implications For Seed Dispersal Across Human-Modified Landscapes, Skye Cahoon May 2020

The Role Of Personality In Large Nut Dispersal By Sciurus Carolinensis And Its Implications For Seed Dispersal Across Human-Modified Landscapes, Skye Cahoon

Honors College

Small mammals are well known seed dispersers, but their efficiency at seed dispersal is directly affected by their personality type. Anthropomorphic habitat change shifts the distribution of personalities within small mammal populations, thus altering the mechanisms by which seeds are dispersed across these areas. Little is known about how small mammals interact with sidewalks, roads, or parking lots during the seed dispersal process despite these areas’ prevalence within human modified landscapes and the importance of understanding the ways in which seeds are transported across anthropomorphically altered regions. The goal of this study is to explore the role of personality in …


Characterizing The Range Shifts Of Two Peromyscus Species In Maine, Molly Bennett May 2020

Characterizing The Range Shifts Of Two Peromyscus Species In Maine, Molly Bennett

Honors College

In a changing climate, two species of mice in Maine (Peromyscus maniculatus and Peromyscus leucopus) are currently undergoing range shifts. The objective of my thesis is to determine the historical and current range of each species within the state of Maine. I used two approaches. I assembled ear biopsies collected this summer in Acadia National Park and throughout the state by the Gardner and Levesque labs to genotype the mice as either P. maniculatus or P. leucopus. Additionally, I summarized research that denotes where the two species were historically present around the state. These species are functionally impossible to tell …
