title: Wood density and decay dynamics of pentachlorophenol-treated wooden posts for four species in Minnesota, USA

description: Wood decay measurements collected from fence posts that were treated with a 5% oil solution of pentachlorophenol in 1942. Fence posts were installed at the University of Minnesota's Cloquet Forestry Center in Cloquet, MN.
description: A wooden fence post experiment was installed at the University of Minnesota's Cloquet Forestry Center (CFC) in 1942. Posts were originally treated in a 5% oil solution of one part pentachlorophenol dissolved in four parts of kerosene by soaking in an upright position in an open oil drum. In 2017 wood decay measurements were collected from cross-sectional disks on a subset of these posts. These data could can used to represent moisture loss and decay from pentachlorophenol treatments.

title: Database of Nutrient Composition of Animal Protein Meals

description: An industry survey and an animal experiment were conducted to evaluate compositional variability and DE and ME content of animal protein by-products, and to generate equations to predict DE and ME content based on chemical analysis. For the 220 samples collected, the greatest concentration of CP was observed in blood meal (BM) and least in meat and bone meal (MBM), the greatest concentration of ether extract (EE) was in meat meal and least in BM, with ash content greatest in MBM and least in BM; with Ca and P levels being 36.1 and 16.3% of the ash content, respectively. For the balance experiment, a corn-soybean meal basal diet was used with test diets formulated by mixing 80% of the basal diet with 20% of the animal protein by-product, except for BM which was included at 10 and 20% of the test diets. Ten groups of 24 gilts (final BW = 92.5 ± 7.4 kg) were used, with gilts randomly assigned to the test or the basal diet within each group, resulting in 16 replications per animal protein by-product or basal diet, except for BM determinations (20 replications). Gilts were placed in metabolism crates and offered 2.4 kg daily of their assigned diet for 13 d, with total collection of feces and urine during the last 4 d. Gross energy was determined in the diets, feces, and urine to calculate DE and ME content of each ingredient by the difference procedure, using DE and ME content of the basal diet as covariates among groups of pigs. The DE content of the animal protein by-products ranged from 5,367 to 2,567 kcal DE/kg of DM, and ME ranged from 4,783 to 2,340 kcal ME/kg DM. Using all animal protein by-products, the best fit equations were as follows: DE, kcal/kg DM = -2,468 + (1.26 × GE, kcal/kg DM), with R2 of 0.84, SE = 390, and P < 0.01; ME, kcal/kg DM = -2,331 + (1.15 × GE, kcal/kg DM), with R2 of 0.86, SE = 327, and P < 0.01). The apparent total tract digestibility (ATTD) of Ca and P were also determined using the difference procedure, with the average ATTD of Ca and P for the animal protein by-products, excluding BM and FM, being 27.1 and 39.1%, respectively. These data indicate that DE and ME varied substantially among the animal protein by-products and sources, and that a variety of nutritional components can be used to accurately predict DE and ME for finishing pigs. In addition, it appears that high dietary inclusion rates of animal protein by-products may result in low ATTD estimates of Ca and P, which may be due to excessive concentrations of total Ca and P affecting digestibility.
description: These data are the result of analyzes conducted on 220 samples of animal by-products meals such as meat and bone meal, meat meal, chicken by-product, chicken meal, among others. The database allows animal nutritionists to compare and evaluate nutrient and energy concentration among sources of ingredients and among ingredients.

title:  Microsatellite data for modern and historical lingonberry in northeastern Minnesota 

description: Partially clonal species are subject to the same evolutionary forces experienced by obligately sexual species, but the variety of potential responses at the population level is much more diverse, ranging from inbreeding to a loss of sexual reproduction. These responses have different genetic outcomes and can interact with each other and other species-level characteristics, such as dispersal and lifespan, to influence the genotypic and genetic diversity of populations through time and across a species range. In this study, we compared the historical and modern population genetics of Vaccinium vitis-idaea (lingonberry) samples from a warm range edge region of the species’ circumboreal distribution. Using 18 polymorphic microsatellite loci in 261 historical and modern samples, we answered three questions: 1) Has genetic diversity been lost through the last six decades?, 2) Do modern populations show signs isolation or low differentiation?, and 3) What are the genotypic and genetic signals of clonality in modern populations? Lingonberry currently appears to be genetically robust at a warm range edge. This study also reveals the variety of reproductive strategies a partially clonal species and can display within a small area, and lays the groundwork for long-term monitoring of geographically proximate populations with vastly different levels of clonal vs. sexual reproduction in region experiencing significant warming.

title: Phenotype and SNP marker data for an intermediate wheatgrass (Thinopyrum intermedium) nested association mapping (NAM) population evaluated in St. Paul, MN and Salina, KS in 2017 and 2018

description: An intermediate wheatgrass (Thinopyrum intermedium) Nested Association Mapping (NAM) population was evaluated at the University of Minnesota Agricultural Experiment Station in St. Paul, MN and The Land Institute in Salina, KS for two years (2017 and 2018). The population (n = 1,168 with both phenotype and genotype data) consisted of ten families where each progeny shares one common parent and was planted in a RCBD design with two blocks surrounded by a border plant. The phenotypic dataset includes 33 traits ranging from morphological, maturity, yield components and domestication traits, and a note column which indicates whether the plants were later identified as selfs and/or other observations. The genotype data was derived from genotyping by sequencing and includes over 8,000 SNP markers. The consensus genetic map was created in JoinMap and used for linkage mapping both within and combined across populations.

title:  Dopant segregation inside and outside dislocation cores in perovskite BaSnO 3 and reconstruction of the local atomic and electronic structures 

description: Distinct dopant behaviors inside and outside dislocation cores are identified by atomic-resolution electron microscopy in perovskite BaSnO3 with considerable consequences on local atomic and electronic structures. Driven by elastic strain, when A-site designated La dopants segregate near a dislocation core, the dopant atoms accumulate at the Ba sites in compressively strained regions. This triggers formation of Ba-vacancies adjacent to the core atomic sites resulting in reconstruction of the core. Notwithstanding the presence of extremely large tensile strain fields, when La atoms segregate inside the dislocation core, they become B-site dopants, replacing Sn atoms and compensating the positive charge of the core oxygen vacancies. Electron energy-loss spectroscopy shows that the local electronic structure of these dislocations changes dramatically due to segregation of the dopants inside and around the core ranging from formation of strong La-O hybridized electronic states near the conduction band minimum to insulator-to-metal transition.

title: Supporting Data for “Why So Slow? Mechanistic Insights from Studies of a Poor Catalyst for Polymerization of ε-Caprolactone”

description: These files contain data along with associated output from instrumentation supporting all results reported in Stasiw, D. E.; Mandal, M.; Neisen, B. D.; Mitchell, L. A.; Cramer, C. J.; Tolman, W. B. Why so slow? Mechanistic insights from studies of a poor catalyst for polymerization of ε-caprolactone. Inorg. Chem., 2016, 56, 725–728. Polymerization of ε-caprolactone (CL) using an aluminum alkoxide catalyst (1) designed to prevent unproductive trans binding was monitored at 110 °C in toluene-d8 by 1H NMR and the concentration versus time data fit to a first-order rate expression. A comparison of t1/2 for 1 to values for many other aluminum alkyl and alkoxide complexes shows much lower activity of 1 toward polymerization of CL. Density functional theory calculations were used to understand the basis for the slow kinetics. The optimized geometry of the ligand framework of 1 was found indeed to make CL trans binding difficult: no trans-bound intermediate could be identified as a local minimum. Nor were local minima for cis-bound precomplexes found, suggesting a concerted coordination–insertion for polymer initiation and propagation. The sluggish performance of 1 is attributed to a high-framework distortion energy required to deform the “resting” ligand geometry to that providing optimal catalysis in the corresponding transition-state structure geometry, thus suggesting a need to incorporate ligand flexibility in the design of efficient polymerization catalysts..

title:  Century-scale wood nitrogen isotope trajectories from an oak savanna with variable fire frequencies 

description: Fire frequency exerts a fundamental control on productivity and nutrient cycling in savanna ecosystems. A single fire event often increases short-term nitrogen (N) availability to individual plants, but repeated burning causes ecosystem carbon and N losses and can ultimately decrease soil organic matter and N availability. However, these effects remain poorly understood due to limited long-term biogeochemical data. Here, we leveraged one of the longest running prescribed burn experiments (established in 1964) to evaluate how fire frequency and changing vegetation composition influenced wood stable N isotopes (δ15N) across space and time. We developed multiple δ15N records across a burn frequency gradient from precisely dated Quercus macrocarpa tree-rings in an oak savanna at Cedar Creek Ecosystem Science Reserve, Minnesota, USA. Sixteen trees were sampled across four treatment stands that varied in temporal onset of burning and burn frequency, but were consistent in overstory species representation, soil characteristics, and topography. Burn frequency ranged from an unburned control stand to a high fire-frequency stand that burned in four of every five years during the past 55 years. Because N stocks and net N mineralization rates are currently lowest in frequently burned stands, we hypothesized that wood δ15N trajectories would have declined over time in all burned stands, but at a rate proportional to fire frequency. We found that wood δ15N records within each stand were remarkably coherent in their mean state and trend through time. A gradual, temporally synchronous decline in wood δ15N occurred in the mid 20th century in the no-, low-, and medium-fire stands, whereas there was no trend in the high-fire stand. The decline in the three stands did not systematically coincide with the onset of prescribed burning. Thus, we found limited evidence for variation in wood δ15N that could be attributed directly to long-term fire frequency in this prescribed burn experiment in temperate oak savanna. Our wood δ15N results may instead reflect decadal-scale changes in vegetation composition and abundance due to early to mid 20th century fire suppression.

title:  Measurement of Antibiotics in Water and Sediment: Determining Minnesota's Antibiotic Footprint 

description: Antimicrobial resistance is considered to be one of the greatest global public health threats of the 21st century. The discharge of antibiotics into the environment may increase antimicrobial resistance as well as disrupt proper ecosystem functioning. Thus, evaluating the antibiotics present in the environment as well as the contributing factors to their presence in the environment will provide invaluable information for improving water quality and protecting human and ecosystem health. This dissertation investigates the presence of antibiotics in water and sediment in both wastewater treatment effluent and agricultural animal affected areas throughout Minnesota. This is to provide a fine scale as well as a broadscale approach with multiple samples at each site at sites across Minnesota. Additionally, a snapshot of the antibiotics present and long term trends of antibiotics in the environment are investigated through water and sediment samples, respectively.
description: Data files here include two summary documents for the 2018 and 2019 water and sediment samples. These include sampling locations as well as antibiotic concentrations. There are also individual spreadsheets that include the raw data and all of the calculations done to obtain the final numbers in the summary documents.
