Complex Systems Analysis In Selected Domains: Animal Biosecurity & Genetic Expression, Luke Trinity
Complex Systems Analysis In Selected Domains: Animal Biosecurity & Genetic Expression, Luke Trinity
Graduate College Dissertations and Theses
I first broadly define the study of complex systems, identifying language to describe and characterize mechanisms of such systems which is applicable across disciplines. An overview of methods is provided, including the description of a software development methodology which defines how a combination of computer science, statistics, and mathematics are applied to specified domains. This work describes strategies to facilitate timely completion of robust and adaptable projects which vary in complexity and scope. A biosecurity informatics pipeline is outlined, which is an abstraction useful in organizing the analysis of biological data from cells. This is followed by specific applications of …
Factors Affecting The Adoption Of Automated Wood Pellet Heating Systems In The Northeastern Us And Implications For The Transition To Renewable Energy, Laura Edling
Graduate College Dissertations and Theses
Public and private incentive programs have encouraged conversions to high efficiency, low emissions wood heating systems as a strategy to promote renewable energy and support local economies in the Northeastern US. Despite these efforts, the adoption of these systems remains slow. The study that is the subject of this dissertation examines several social, economic, policy and environmental factors that affect the decisions of individuals and small-scale institutions (local business and community facilities) to transition to automated wood pellet boilers and furnaces (AWPH) utilizing local fuel sources. Due to the complexity and risk associated with conversion, the transition to these systems …
The Environmental Microbiome In A Changing World: Microbial Processes And Biogeochemistry, Stephanie Juice
The Environmental Microbiome In A Changing World: Microbial Processes And Biogeochemistry, Stephanie Juice
Graduate College Dissertations and Theses
Climate change can alter ecosystem processes and organismal phenology through both long-term, gradual changes and alteration of disturbance regimes. Because microbes mediate decomposition, and therefore the initial stages of nutrient cycling, soil biogeochemical responses to climate change will be driven by microbial responses to changes in temperature, precipitation, and pulsed climatic events. Improving projections of soil ecological and biogeochemical responses to climate change effects therefore requires greater knowledge of microbial contributions to decomposition. This dissertation examines soil microbial and biogeochemical responses to the long-term and punctuated effects of climate change, as well as improvement to decomposition models following addition of …
Consumption Of Microplastics Impacts The Growth And Fecal Properties Of The Marine Copepod, Acartia Tonsa, Emily Ann Shore
Consumption Of Microplastics Impacts The Growth And Fecal Properties Of The Marine Copepod, Acartia Tonsa, Emily Ann Shore
Graduate College Dissertations and Theses
Microplastics (mm) are ubiquitous in the global environment and are increasingly recognized as a biological hazard, particularly in the oceans. Due to the small and pervasive nature of these particles, zooplankton have been known to consume and egest microplastics. Though zooplankton play critical roles in marine food webs and in carbon storage through carbon rich fecal pellets, we know little about the effects of microplastics on early life stage growth, reproductive output, and carbon storage. Here, I investigated the effects of ingestion of low-density Polystyrene beads (5 µm) by the copepod Acartia tonsa on (1) early life stage (naupliar) growth, …
From Tap To Table: Consumer Values, Producer Attitudes, And Vermont Maple Syrup In A Dynamic Landscape, Aidan Conor Mccracken
From Tap To Table: Consumer Values, Producer Attitudes, And Vermont Maple Syrup In A Dynamic Landscape, Aidan Conor Mccracken
Graduate College Dissertations and Theses
Harvesting the sap of maple trees [Acer saccharum] for use in the production of syrups and sugars has a storied history stretching back to the pre-Columbian practices of North America’s indigenous peoples. Since its adaptation by European settlers in the late seventeenth century and into the present day, the production of maple syrup has become especially integral to the livelihoods and cultural identities of farmers in Vermont. While oftentimes esteemed as a timeless agrarian tradition, market forces and environmental changes have led maple syrup producers (or sugarmakers) to adopt new production practices that scarcely resemble the taps, buckets, and draft …
