Effects of nutrient addition on endophyte-associated grass invasion in a long-term, old-field community experiment
— 2021-05-11 Strictly vertically transmitted (hereditary) Epichloë spp. fungal endophytes are symbionts with cool-season pooid host grasses. Such endophytes may increase host invasiveness in the non-native, introduced ranges. However, the costs and benefits for the host can vary with the abiotic and biotic growing conditions, and the endophyte may become locally or temporally extinct when costs outweigh benefits. Our long-term field experiment involved seven Schedonorus pratensis (meadow fescue) cultivars hosting Epichloë uncinata endophyte, which represent host-grass populations with different genetic background and Epichloë infection levels. In the first six years, the host grasses persisted but did not become invasive in an old-field plant community, regardless of their endophyte infection frequency. We hypothesized that increasing nutrient availability would decrease endophyte costs and thus increase the host’s success and abundance. We fertilized half of the plots for four additional years and re-examined S. pratensis invasiveness. We predicted that increased nutrient availability would increase S. pratensis abundance and E. uncinata frequency and concentration, as well as decrease plant community diversity, relative to unfertilized plots. Fertilization increased endophyte concentrations in three host populations with low endophyte infection frequency. However, E. uncinata did not enable S. pratensis populations to achieve high abundance or to reduce plant community diversity, with or without fertilization.

Dataset for: The effects of partially replacing animal protein sources with full fat black soldier fly larvae meal (Hermetia illucens) in nursery diets on growth performance, gut morphology, and immune response of pigs
— 2021-03-18 One hundred and forty-four newly weaned pigs (21 days of age) were used to determine the effect of partially replacing animal protein sources with black solider fly larvae meal (BSFLM) in nursery diets on growth performance, gut morphology, and immune response. After weaning, pigs were placed in 24 pens (6 pigs per pen) and pens were randomly assigned to one of four dietary treatments (study d 0; n = 6), which were fed over 3 phases (phases I, II, and III were fed for 7, 14, and 21 days, respectively). Two nursery diets were formulated with 25% (LowFF) and 50% (HighFF) of the animal protein sources replaced by full fat BSFLM. Conventional nursery diets including animal protein sources without (CON-) and with antibiotics (220 mg Aureomycin per kg of complete feed; CON+) served as controls. On day 8, two pigs per pen were sacrificed to collect organ weights and for intestinal histomorphological measurements. On days 9 and 23, two pigs per pen were vaccinated with the novel antigen ovalbumin (OVA). Blood samples were collected on days 9, 23, and 38 to assess concentrations of plasma haptoglobin and OVA-specific immunoglobulins G (IgG) and IgG1. On day 38, the same two pigs per pen underwent a dermal hypersensitivity test and skin-fold thickness was measured at 0, 6, 24, and 48 h post-intradermal injection with OVA.

Soil moisture, vegetation analysis and raw logger research dataset: Elora Research Station, Elora, Ontario [Canada] May 19, 2015 to September 16, 2016
— 2016-08-30 Aaron Berg's Research Group in the Department of Geography, College of Social and Applied Human Sciences, University of Guelph, collects information from five different agricultural fields at the Elora Research Station. The purpose of the study is to evaluate the effect of increased vegetation on backscatter measurements as collected from the RADARSAT-2 satellite. This dataset contains backscatter, soil moisture, dielectric, vegetation water content (W), and leaf area index (LAI) measurements. The POGO probe collects soil moisture and dielectric constant measurements from various sites and depths on each field. The RADARSAT-2 satellite collects backscatter (dB) which can be derived to estimate soil moisture, leaf area index, and volumetric water content measurements. The LAI-2200C Plant Canopy Analyzer was used to measure leaf area index. The study aims to determine the point at with the RADARSAT-2 satellite loses sensitivity in backscatter as a result of increased vegetation growth. This is analyzed by comparing the strength of the relationship between RADARSAT-2 backscatter and field based soil moisture, LAI, and W during vegetation development. Then, using piecewise regression before and after the derived inflection point. This set includes data from May 19th, 2015 to September 16th, 2016.

Improving fungicide efficacy for management of Cercospora leaf spot in sugarbeet
— 2021-06-30 <p><b>NOTES ON BROWSING:</b></p><p>Click on the "Tree" view to identify folder structure and related files.</p> Cercospora leaf spot is a serious disease that reduces sugarbeet yield and sugar quality. Due to fungicide resistance of C. beticola, effective fungicide options are becoming increasingly limited. Improving the efficacy of remaining fungicides is necessary to ensure their use is both effective and contributes to sustainable fungicide practices. The use of deposition aids and optimum carrier volumes to improve fungicide penetration and deposition may provide more effective applications, resulting in improved disease management. The objectives of this research are: (i) to evaluate the effect of a deposition aid on fungicide efficacy at different application carrier volumes, (ii) to evaluate the effect of the deposition aid MVO on spray deposition and penetration within the sugarbeet canopy.

Winter warming effects on overwinter survival, energy use, and spring emergence of the bean leaf beetle Cerotoma trifurcata 2010 to 2013 [South-central Ontario, Canada]
— 2016 The original publication (see Related Publication) and this data set should both be cited if these data are used; see the original publication for detailed methods. The potential effects of warmer winters and fluctuating thermal regimes on overwintering bean leaf beetle (Cerotoma trifurcata) using field and laboratory experiments was assessed. The 3 year (Winter of 2010-2011, 2011-2012, and 2012-2013) field experiment involved three warming levels: heated ~4 degrees Celsius above ambient, unheated with snow cover left intact, and unheated with snow cover removed. Survival and date of emergence were examined in all years, and beetle lipid content was analyzed in one year to determine rates of energy use. The laboratory experiment assessed effects of frequency and duration of fluctuating thermal regimes on survival.

Can application of enhanced efficiency fertilizers at planting reduce N losses from grain corn production in Ontario?
— 2019-12-10 This work was supported through the 4R Research Network with funding provided by Agriculture and Agri-Food Canada’s AgriInnovation Program (Growing Forward 2), contributing Fertilizer Canada member companies to the North American 4R Research Fund and Fertilizer Canada’s Science Cluster program. The Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA)/University of Guelph Partnership provided funding for use of the Elora Research Station fields. This project evaluated a combination of Right Time and Right Product practices aimed at reducing these environmental nitrogen losses from corn. We addressed the following questions: 1) Can application of the Right Product at planting reduce environmental losses compared to the regular fertilizer application? 2) Can application of nitrogen at the Right Time reduce environmental losses compared to the fertilizer application at planting? 3) Can application of a combination of Right Product and Right Time provide additional reduction of environmental nitrogen losses? The Right Product consisted of either an urea-based enhanced efficiency fertilizer (EEF, urea with nitrification and urease inhibitor) or an urea-ammonium-nitrate (UAN)-based EEF (UAN with nitrification and urease inhibitor). The Right Time consisted in delaying application until the 6-8th leaf stage (application as side-dress). Environmental nitrogen losses considered were emissions of the greenhouse gas nitrous oxide and leaching losses in the form of nitrate.

Replication Data for: Canadian Recreational Anglers’ Preferences to Fish on Watersheds Adopting Novel Genomic Technologies
— 2022-02-10 This study employs a contingent valuation survey to elicit willingness-to-pay (WTP) from Canadian recreational anglers to fish on their preferred watersheds were these watersheds to adopt novel environmental DNA (eDNA) toolkits. The survey gathered responses from 999 Canadian recreational anglers using a double-bounded dichotomous-choice format. In comparison to a baseline that quantitatively elicits anglers’ WTP for the use of eDNA toolkits, this study also estimates how additional information regarding genomic technologies influences WTP. Results indicate that the provision of additional information has no significant effect on respondents’ WTP. On average, Canadian recreational anglers are willing to pay premiums between 7%-23% of their reported annual fishing expenditure to fish on otherwise-identical watersheds adopting novel eDNA toolkits. Findings from this study can be used to inform fisheries management policies, and evidence suggests Canadian recreational anglers have strong preferences for the adoption of eDNA technology regardless of the information they are exposed to. The manuscript associated with this data is currently being submitted for publication.
