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

A Novel Mechanism For Mechanosensing By Endothelial Cells, Jennifer Macdowell
A Novel Mechanism For Mechanosensing By Endothelial Cells, Jennifer Macdowell
Honors College
The formation of new vasculature is an essential process, but can also be utilized by cancerous cells. Angiogenesis requires the directed migration of the endothelial cells lining the nascent blood vessels. This process is largely mediated by integrin, which plays a key role in the interplay between sensing a force in the extracellular matrix (ECM) and transducing this signal, a process termed mechanotransduction. Through cell-ECM focal adhesions, integrin mediates the signaling both into and out of the cell, promoting growth of focal adhesions and subsequent cell spreading and migration. In order to study focal adhesion dynamics related to force, we …
Bayesian Analysis Of Data On Nest Success For Marsh Birds, Sean Hardy
Bayesian Analysis Of Data On Nest Success For Marsh Birds, Sean Hardy
Honors College
Bayesian methods are an increasingly popular form of statistical analysis which uses informative prior distributions to help calculate posterior distributions of models that represent different hypotheses. Frequentist methods are contrasting methods that are used more commonly and more well known, but have come under recent criticism. I examined data gathered by Ellen Robertson, who used information theoretic methods for a Masters’ Thesis in Ecology and Environmental Science at the University of Maine to analyze the daily survival probabilities of marsh birds with a Bayesian perspective in order to get a sense of the Bayesian analysis. Results were as expected; when …

Fast Pyrolysis Of Muconic Acid And Formic Acid Salts, Laura Duran
Honors College
Lignocellulosic biomass is emerging as a sustainable resource for the production of alternative liquid fuels. As the need to lessen dependence on petroleum sources grows, lignocellulosic feedstocks are being investigated as a renewable, abundant source of energy. Chemical pulping processes include a high-lignin by-product, black liquor, which is already used for fuel in industry. Black liquor is burned to generate steam and electricity and to recover pulping chemicals. Currently, the thermochemical conversion of black liquor to liquid fuel is being researched at The University of Maine. In this black liquor research, an intermediate lignin-derived acid, muconic acid, and formic acid …

Economic Efficiency In Fisheries And Aquaculture, Paul Molyneaux
The Catch
Reflection of the author as a worker looking to make the best use of his time and energy. His innate understanding of the principles of ecological economics followed by exposure to the discipline’s advancing theories leads to a revelation regarding the backwards logic of fisheries and aquaculture policy thus far, and the decline in real seafood production.Along with many others, Molyneaux looks to ecological economics to create a new paradigm for sustainable fisheries.

Marine macroinvertebrates are ideal sentinel organisms to monitor rapid environmental changes associated with climatic phenomena. These organisms build up protective exoskeletons incrementally by biologically-controlled mineralization, which is deeply rooted in long-term evolutionary processes. Recent studies relating potential rapid environmental fluctuations to climate change, such as ocean acidification, suggest modifications on carbonate biominerals of marine invertebrates. However, the influence of known, and recurrent, climatic events on these biological processes during active mineralization is still insufficiently understood. Analysis of Peruvian cockles from the 1982–83 large magnitude El Nin˜o event shows significant alterations of the chemico-structure of carbonate biominerals. Here, we show that …

Eager: Collaborative Research: Developing Transformation Technologies For Porphyra, Susan H. Brawley
University of Maine Office of Research Administration: Grant Reports
The genome of the marine red alga Porphyra umbilicalis is being sequenced by the Joint Genome Institute. The sequence information will help scientists address many fundamental questions, because Porphyra spp. belong to an ancient eukaryotic lineage, are important human foods ("nori"), have complex life histories, and---even compared to other intertidal organisms--- possess an unusually stress-tolerant metabolism. Computer-based analyses of the new genomic data will be sufficient to address some research questions, but most studies (e.g., the basis of Porphyra's tolerance to extreme drying or high light) will require experimental approaches based upon bioinformatics analyses. This project will develop the essential …

Agent-Based Modeling Of Harvest Decisions By Small Scale Forest Landowners In Maine, Usa, Jessica Leahy, Erika Reeves, Kathleen Bell, Crista L. Straub, Jeremy Wilson

Small-scale forests are an excellent example of coupled social-ecological systems, which involve human and biophysical subsystems with complex two-way feedback interactions. The multifaceted nature of landowner decisions drives a significant need to better understand decision-making processes, reactions to policy, and combined impacts on ecosystems in a comprehensive manner. Small-scale forests require an integrated approach to modeling the social and biophysical components comprehensively. Agent-based modeling involves modeling individualistic behavior and interpreting patterns that emerge. The interaction between agents and their environments makes this a valuable tool to assess repeated decisions of individual landowners responding to changing environmental conditions. Agent-based models can …

Coastal managers are frequently required to consider the economic implications of their decisions, but economic data needed to support decisions is frequently lacking. This paper discusses the creation of a national data set that measures economic activity related to the oceans and Great Lakes of the U.S. Measures include employment, wages, establishments, and output. The data is derived from existing data maintained by the federal government to assure temporal and spatial consistency of measurement. The data set defines the “ocean economy” through a combination of industry and geographic location features to measure 21 separate industries in 6 sectors, at the …
