title: Implementing an adaptive, two-tiered SARS-CoV-2 wastewater surveillance program on a university campus using passive sampling

description: Wastewater-based surveillance (WBS) has been increasingly applied at sites upstream of the wastewater treatment plant (WWTP) to monitoring SARS-CoV-2 RNA at the building-scale. The dataset described is the result of an eight-month long passive sampling campaign on the University of Waterloo (Waterloo, ON) campus. The goal was to determine if passive sampling could support institution-level decision-making. In brief, the method involved the 24-hour deployment of cotton gauze passive samplers enclosed in a 3D printed housing vessel. Upon collection, passive sampling materials were washed and the resulting solids were concentrated. RNA extraction from solids was performed using a kit-based extraction method. Two regions of the SARS-CoV-2 nucleocapsid gene (e.g., N1, N2) as well as the endogenous indicator pepper mild mottle virus (PMMoV) were quantified using RT-qPCR. Our study demonstrated that cotton gauze was able to identify trends in SARS-CoV-2 burdens on campus and that viral concentrations on passive samplers were significantly correlated with known clinical cases in the catchment. The dataset also includes monitoring data collected at the nearby municipal WWTP which offers insight to transmission dynamics at both sampling scales. Further developing affordable WBS methodologies will benefit future monitoring efforts under novel public health scenarios.

title: Multiscale transport and 4D time-lapse imaging in Precision Cut Liver Slices (PCLS)-Supplementary Data

description: Data for submitted manuscript. Abstract: Background. Monitoring cellular processes across different levels of complexity, from the cellular to the tissue scale, is important for understanding tissue structure and function. However, it is challenging to monitor and estimate these structural and dynamic interactions within three-dimensional (3D) tissue models. Objective. The aim of this study was to design a method for imaging, tracking, and quantifying 3D changes in cell morphology (shape and size) within liver tissue, specifically a precision-cut liver slice (PCLS). A PCLS is a three-dimensional (3D) model of the liver that allows the study of the structure and function of liver cells in their native microenvironment. Methods. Here we present a method for imaging liver tissue during anisosmotic exposure in a multispectral four-dimensional manner. Three metrices of tissue morphology were measured to quantify the effects of osmotic stress on liver tissue. We estimated the changes in the volume of whole precision cut liver slices (PCLS), quantified the changes in nuclei position, and calculated the changes in volumetric responses of tissue-embedded cells. Results. During equilibration with cell-membrane-permeating and non-permeating solutes, the whole tissue experiences shrinkage and expansion. As nuclei showed a change in position and directional displacement under osmotic stress, we demonstrate that nuclei could be used as a probe to measure local osmotic and mechanical stress. Moreover, we demonstrate that cells change their volume within tissue slices as a result of osmotic perturbation and that this change in volume is dependent on the position of the cell within the tissue and the duration of the exposure. Conclusion. The results of this study have implications for a better understanding of multiscale transport, mechanobiology, and triggered biological responses within complex biological structures.

title: Location selection for optimal sensor placement for prediction of hip angle in three dimensions with wearable strain sensors

description: The study was conducted to determine optimal placement of strain sensors for capturing hip joint movement during running. Five subjects donned tight athletic pants having a grid of optical motion capture markers on the right hip area. The motion capture experiment was run with static pose and running at three speeds. Five participants (P01 to P05) were asked to run on a treadmill at three fixed speeds - 8 km/h, 10 km/h and 12 km/h - for two minutes per session. The set of markers were evaluated to determine which pairs resulted in greater movement in order to inform the decision of where to place future strain sensors.

title: Quantifying litterfall and its carbon and nitrogen content in Beverly swamp

description: This litterfall weight and their carbon to nitrogen ratio (C:N) contents were measured as part of Veronica Santia’s undergraduate program (Senior Honors Thesis) at the Faculty of Environment, University of Waterloo under the supervision of Professor Maria Strack. The purpose of the research was to quantify the litterfall deposit of temperate swamps and their carbon to nitrogen contents towards assessing their role in the ecosystem’s carbon cycling process. In particular, litter collection surveys surveys were conducted during September and October 2022 at Beverly Swamp (43.366N, 80.12W). Swamp litterfall quantity was obtained with 50cm x 50cm wooden litter traps and 1m long wooden stakes with 1mm diameter mesh attached to the fame. Each litter trap was installed at the center of four 20m x 50 m plots installed along 200 m transect at the onset of the fall season. Collected litter was dried in the oven at 65C for 48 hours before removing and weighing, while the Carbon to Nitrogen (C:N) of the litter was determined with 4010 Elemental analyzer that is coupled to a Delta Plux XL continuous flow isotope ration mass spectrometer (CFIRMS)after pre-processing (e.g. grinding). Total litterfall of the swamp is ~239 g/m2, while the average C:N value of 31.7 was reported for the analyzed data. Peak litterfall was observed around October which thereafter dwindled into November. This dataset is expected to improve our understanding of swamp peatland carbon in the temperate region of Canada and can also be used for initializing and calibrating ecological models in the area.

title: Paraglacial terrace distribution and landscape morphometry in the Fraser Basin

description: This dataset relates to a publication (in revision) at Earth Surface Processes & Landforms entitled "Detection of paraglacial sediment supply using detrital 10Be in postglacial landscapes of south west British Columbia". The study uses spatial concentrations of cosmogenic radionuclides (CRNs) to identify sources of sediment in the Fraser River basin, utilizing the observation that CRN concentrations are distinct between glacially derived sediment (from past glacial periods), and sediment produced by contemporary denudation of exposed bedrock. Our observation suggest that despite the prevalence of paraglacial terrace fills in the lower Fraser River basin, glacially-derived sediment sourced from terrace fills only contributes ~15% to the modern Fraser River sediment load. The key datasets presented here are 1) an inventory of paraglacial terrace surfaces between Soda Creek and Lady Franklin Rock, that were identified from high-resolution LiDAR data using the methods of Clubb et al. (2017) (see Clubb, F.J., Mudd, S.M., Milodowski, D.T., Valters, D.A., Slater, L.J., Hurst, M.D. and Limaye, A.B., 2017. Geomorphometric delineation of floodplains and terraces from objectively defined topographic thresholds. Earth Surface Dynamics, 5(3), pp.369-385.), 2) a simplified regional bedrock geology map, 3) various topographic metrics that are used to compare against landscape denudation rate estimates, and 4) datasets used in the generation of CRN-derived denudation rate estimates across the Fraser River Basin. Final datasets included in "Detection of paraglacial sediment supply using detrital 10Be in postglacial landscapes of south west British Columbia" by Dingle et al. (in review).

title: Portrait de l'empowerment des personnes enceintes au Québec dans leur suivi prénatal

description: L'empowerment dans un contexte prénatal, bien que plébiscité, peut rencontrer des défis dans son application, notamment avec la médicalisation des soins prénataux. Face à ces défis, nous avons voulu dresser un portrait du niveau d'empowerment des personnes enceintes au Québec et identifier les facteurs susceptibles de l'influencer, dont les technologies numériques. Nous avons mené une enquête quantitative anonyme auprès de personnes enceintes ou ayant accouché au cours de la dernière année au Québec. Les participants ont répondu à des questions sociodémographiques, ainsi qu'à des questions sur leur grossesse et leurs soins prénataux. Elles ont ensuite été interrogées sur leur compréhension et leur perception du concept d'empowerment. On leur a également demandé de remplir l'échelle d'empowerment de Klima et de ses collègues, de donner leur opinion sur l'influence des facteurs sur leur processus d'empowerment, leur utilisation des ressources pour soutenir leur empowerment.

title: Experimental seed addition trials for the wood-poppy (Stylophorum diphyllum)

description: These data were collected as part of a PhD project to test the drivers of rarity of the wood-poppy (Stylophorum diphyllum). The wood-poppy is listed as endangered in Canada's Species at Risk Act (SARA). The study tests the efficacy of species distribution models (SDMs) to estimate suitable habitat for experimental seed addition trials within nine 1-hectare (100 m x 100 m) sites in southern Ontario. Within each site we selected nine plots stratified by observed soil moisture and canopy light levels. We caged half of the sub-plots to exclude seed predators (i.e., rodents). We planted 25 seeds into each sub-plot (4050 total seeds). We measured abiotic microsite characteristics in each plot including canopy light, soil moisture, and relative temperature differential. We planted the seeds in August 2021, recorded seedling emergence in spring 2022, and year one seedling survival in 2023. We removed cages with no germination and opened cage tops that were restricted plant growth throughout our censuses. We found the SDMs did not predict seedling emergence or short-term survival, suggesting there is not a lack of suitable habitat available. Instead, we found dispersal limitation coupled with seed predation drive rarity (at least for early life-stages). The files contain year one emergence (2022), year two survival (2023), and environmental plot (n=81) data. These files are associated with Emma R. Neigel’s PhD dissertation and the article, "Dispersal limitation and seed predation drive rarity of a plant species at its range edge. Neigel, Emma R., Timothy D. Schwinghammer, and J.L. McCune. Journal of Ecology (in-press, 2025)".
