Effects Of Flaxseed-Based Feed Supplement On Production Performance, Energy Utilization, Milk Fatty Acid Profile, And Enteric Methane Emissions In Jersey Cows Grazing Mixed Grass-Legume Pasture, Md Atikur Rahman

Master's Theses and Capstones

This study investigated the effect of an extruded flaxseed-based feed supplement ‘LinPRO-R (LNPR)’ on milk production and composition, milk FA profile, nutrient digestibility, ruminal metabolism, purine derivatives (PD) excretion, and enteric methane (CH4) emissions in grazing dairy cows during the summer season. Eighteen multiparous and 2 primiparous mid-lactating organic Jersey cows (128 ± 52 DIM) were used in a randomized complete block design. cows grazed mixed grass-legume pasture (Dactylis glomerata L., Trifolium repens L., Trifolium pratense L., Lolium perenne L., Phleum pratense L.) overnight (herbage allowance = 15 kg of DM/cow/day) following a strip grazing method and fed partial total-mixed …

Exploring Forest Structural Complexity: Scale Effects And Metric Relationships In New England Hardwood Forests, Alex Jed Siebert

Master's Theses and Capstones

Forest structural complexity (FSC) is an informative characteristic in forest management due to its connections to ecosystem resilience, biodiversity, and carbon sequestration. Despite its widespread use, quantifying FSC remains a challenge because of the many attributes that can comprise an assessment of FSC and ambiguity around what exactly is meant by “complexity.” Many assessments of FSC involve metrics derived from lidar data, yet there is not a clear understanding of how spatial extent impacts metrics of FSC. This thesis investigates the influence of spatial extent on FSC metrics and metric relationships in the context of New England mixed hardwood forests. …

Evaluating Growth Patterns Of Beech Bark Disease Fungal Agents Neonectria Faginata And Neonectria Ditissima Under Different In Vitro Conditions, Santiago Rivera Reyes

Master's Theses and Capstones

The co –occurring fungal species Neonectria ditissima and Neonectria faginata are major canker-forming pathogens in the beech bark disease (BBD) systems which has caused restructuring of forests throughout northeastern North America. The role of nutrients in structuring microbial community interactions has been studied in BBD forests stands but has yet to be fully understood and examined under specific in-vitro conditions. This study aimed to investigate how nitrogen, phosphorus, and temperature levels influence the growth, reproduction, and competitive hierarchies between N. ditissima and N. faginata. We performed in-vitro assays where species were first individually and then jointly grown under different concentrations …

Mechanistic Models Of Human Decision-Making And Ecological Dynamics In Small-Scale Fisheries, Sophie Wulfing

Master's Theses and Capstones

Small-scale fisheries are essential to the livelihoods of 40 million people worldwide. They are key sources of nutrients and income for these communities that rely on them. However, understanding the status of these fisheries requires in-depth data collection, often in remote areas. Further, each small-scale fishery is very individualized, and external groups attempting to impose fishing restrictions are often met with low compliance or are unsuccessful in their efforts to conserve fish stocks due to a lack of understanding of either fishing culture or the ecology of the harvested species. In this thesis, I employ various mechanistic models to small-scale …

Relationship Among Police Officers’ Alcohol Use, Child Sexual Abuse Material Exposure And Department Practices And Policies, Mahmuda Akter

Master's Theses and Capstones

This study explores the complex interplay of departmental practices and policies, exposure to child sexual abuse material (CSAM), social support, group connectedness, and gender in relation to alcohol consumption among police officers. The cross-sectional study utilizes self-reported data from 528 police investigators, forensic examiners and others connected with the criminal justice system from across the United States. Analysis reveals exposure to CSAM does not demonstrate a significant correlation with drinking habits among police officers. However, one significant positive relationship was observed between viewing CSAM that involves children aged 6 to 10 and drinking patterns. Furthermore, departmental practices are not associated …

Replacing Ground Corn With Liquid Molasses In Diets Of Jersey Cows Fed Red Clover Baleage: Effects On Milk Production, Nitrogen Efficiency, Energy Utilization, And Enteric Methane Emissions, Adam Lee Konopka

Master's Theses and Capstones

Molasses is a food byproduct rich in sucrose commonly added to the diets of cattle which has been reported to enhance milk production, promote rumen microbial growth, and increase digestibility of nutrients. Variable results obtained when partially replacing starch sources with molasses have led to an increased interest in the dietary conditions under which molasses could optimize the production of dairy cows. We aimed to investigate the effect of partially replacing ground corn with sugarcane liquid molasses on dry matter intake, milk yield and composition, enteric methane emissions, and N utilization in lactating Jersey cows fed red clover baleage. Eighteen …

“An Alarming State Of Evil Among Our Juveniles” A Case Study Of Public Education In Manchester, New Hampshire From 1845-1915, Amy Cummings Sherr

Master's Theses and Capstones

This thesis investigates the effectiveness of compulsory public education laws in Manchester, New Hampshire from 1845-1915, drawing on detailed quantitative and qualitative analysis of school attendance records, legislative proceedings, and media coverage. The thesis identifies shifting objectives in the campaigns for compulsory education laws and child labor laws in New Hampshire over the course of the nineteenth and twentieth centuries which help to explain lackluster enforcement. Reformers re-defined the perceived problems over time which led to new legislation and changing priorities in enforcement. Initially, reformers focused on “idle children” causing trouble and disrupting society. Then with mass immigration to the …

Variable Light Penetration And Chlorophyll Concentrations From A Vertical Profiler In The Gulf Of Maine, With Implications For Remote Sensing And Ecosystem Modeling, Terence W. O'Brien

Master's Theses and Capstones

Variability in light field penetration into the ocean alters both radiant heat flux and oceanic primary production. Both are increasingly important in the context of quantifying biologically-mediated atmospheric carbon fluxes and sea surface temperature increase in a changing climate. Accurate determination of light penetration into the upper ocean depends upon accurate estimates of the depth-resolved water absorption and attenuation properties through the water column, properties that are often assumed homogeneous vertically and slowly variant in time. This thesis explores all-new Gulf of Maine datasets collected using a moored vertical profiler that provides sub-hourly light attenuation profiles with sub-m vertical resolution …

Rare Earth Element Distributions In Forest Soils Across Bedrock Gradients In New Hampshire And Vermont, Ashley Grengs

Master's Theses and Capstones

Within Earth surface systems, forests factor critically in carbon cycling and sequestration and accordingly play an important role in many climate change mitigation strategies. Predictive models of carbon storage require assessments of carbon storage as well as nutrient cycling, which, in turn, has long-term impacts on carbon storage. Nutrient allocations affect tree biomass, leaf growth, stem density, and biodiversity. Yet, bedrock contributions to nutrient allocations are not routinely quantified, even though bedrock compositions can influence soil types, soil pH, and tree species within forest.

Here, I expand on previously developed approaches to conduct a comparative study between eight sites across …

Evaluation Of A Wave Powered Water Pump Performance By Ocean Field Testing And Wec-Sim Modeling, Chelsea Kimball

Master's Theses and Capstones

A rising demand for macroalgae (or seaweed) has led researchers to seek out methods of increasing macroalgae aquaculture yields. Macroalgae is a food product, and may be used in biofuel, animal feed, and fertilizer. Applying upwelling technology to macroalgae aquaculture has been shown to increase biomass yield. A wave-powered upwelling device (or water pump) generates cold, nutrient-rich water flow to the surface of an aquaculture operation. A wave pump device developed at University of New Hampshire was refurbished and outfitted with instrumentation to determine its performance. Testing in the laboratory on both the device and instrumentation was conducted to prepare …

In the accompanying Comment1, He et al. argue that the determinant role of microbial carbon use efficiency in global soil organic carbon (SOC) storage shown in Tao et al. (2023)2 was overestimated because carbon inputs were neglected in our data analysis while they suggest that our model-based analysis could be biased and model-dependent. Their argument is based on a different choice of independent variables in the data analysis and a sensitivity analysis of two process-based models other than that used in our study. We agree that both carbon inputs and outputs (as mediated by microbial processes) matter when predicting SOC …

Season, Not Long-Term Warming, Affects The Relationship Between Ecosystem Function And Microbial Diversity, Melissa S. Shinfuku, Luiz A. Domeignoz-Horta, Mallory J. Choudoir, Serita D. Frey, Kristen M. Deangelis

Faculty Publications

Across biomes, soil biodiversity promotes ecosystem functions. However, whether this relationship will be maintained under climate change is uncertain. Here, using two long-term warming experiments, we investigated how warming affects the relationship between ecosystem functions and microbial diversity across seasons, soil horizons, and warming duration. The soils in these warming experiments were heated +5 °C above ambient for 13 or 28 years. We measured seven different ecosystem functions representative of soil carbon cycling, soil nitrogen cycling, or nutrient pools. We also surveyed bacterial and fungal community diversity. We found that the relationship between ecosystem function and bacterial diversity and the …

Deep Dives And High Tissue Density Increase Mean Dive Costs In California Sea Lions (Zalophus Californianus), Mason R. Cole, Colin Ware, Elizabeth A. Mchuron, Daniel P. Costa, Paul J. Ponganis, Birgitte I. Mcdonald

Center for Coastal and Ocean Mapping

Diving is central to the foraging strategies of many marine mammals and seabirds. Still, the effect of dive depth on foraging cost remains elusive because energy expenditure is difficult to measure at fine temporal scales in wild animals. We used depth and acceleration data from eight lactating California sea lions (Zalophus californianus) to model body density and investigate the effect of dive depth and tissue density on rates of energy expenditure. We calculated body density in 5 s intervals from the rate of gliding descent. We modeled body density across depth in each dive, revealing high tissue densities and diving …

Rainbow Colormaps Are Not All Bad, Colin Ware, Maureen Stone, Danielle Albers Szafir

Center for Coastal and Ocean Mapping

Some 15 years ago, Visualization Viewpoints published an influential article titled Rainbow Color Map (Still) Considered Harmful (Borland and Taylor, 2007). The paper argued that the “rainbow colormap’s characteristics of confusing the viewer, obscuring the data and actively misleading interpretation make it a poor choice for visualization.” Subsequent articles often repeat and extend these arguments, so much so that avoiding rainbow colormaps, along with their derivatives, has become dogma in the visualization community. Despite this loud and persistent recommendation, scientists continue to use rainbow colormaps. Have we failed to communicate our message, or do rainbow colormaps offer advantages that have …
