title: Meteorological and hydrological data from the Alder Creek Watershed, Grand River Basin, Ontario.

description: The Alder Creek field observatory was instrumented by the Southern Ontario Water Consortium as the middle member of three watersheds with different degrees of urbanization. Field data were collected via the deployment of electronic instruments and manual measurements in the Alder Creek watershed to answer questions related to water management at the watershed scale. Field sites were chosen based on: 1) an attempt to distribute measurement locations spatially throughout the watershed, 2) permissions obtained from local residents, businesses, and stakeholders (e.g., the Regional Municipality of Waterloo) for installations, and 3) interest in monitoring local processes such as depression focused recharge. Cellular network telemetry was used to regularly transmit remote field data to a computer at the University of Waterloo. This was part of a “smart” watershed design whereby field data could be reviewed by technicians to make decisions regarding field monitoring and equipment maintenance. Data collection schedules could also be adjusted remotely. This datasets will be also used to support the research objectives of the Global Water Futures Program

title: Beyond Climate Warming: How Salinization Accelerates Deoxygenation in Lakes

description: This dataset provides a harmonized collection of lake- and watershed-scale attributes, time series, and analysis code used to evaluate salinization-driven deoxygenation in lakes across Canada and the contiguous United States. It includes a lake attributes table for 144 study lakes (coordinates, morphometry, residence time, stratification metrics such as BVF(t,S), and deep-water chemistry including hypolimnetic Cl/SC and DO), together with linked watershed descriptors derived from HydroLAKES, GLOBathy, BasinATLAS and global land-use/land-cover products (population density, fraction urban, road density, watershed-to-lake area ratio, climate statistics, and snow cover). Annual mean hypolimnetic DO and salinity proxies are provided for each lake for 1988–2022, along with a companion time-series_plots folder (zip file) containing 144 lake-specific JPG figures that visualize these trends. A separate table lists HydroLAKES waterbodies in Canada and the United States predicted to be at risk of salinization-driven deoxygenation based on the logistic-regression framework described in the associated manuscript. The repository also includes the core Python scripts used for data pre-processing, geospatial extraction, clustering, statistical analyses, and figure generation, enabling users to reproduce and extend the workflows.

title: A general transition metal binding aptamer following the Irving–Williams series

description: Using both Co2+ and Ni2+ as target metal ions, aptamer selections were carried out by immobilization of a DNA library via hybridization. A set of aptamers were obtained although they all showed binding to both metal ions. The Co-1 aptamer was highly enriched in both selections and it is a general metal binding aptamer with binding affinity following the Irving-Williams series: Mn2+ &lt; Fe2+ &lt; Co2+ &lt; Ni2+ &lt; Cu2+ &gt; Zn2+. Using NMR spectroscopy, Co-1 forms new base pairs with a relatively large structural change upon binding to Zn2+, whereas a previously reported Zn1 aptamer has little conformational change upon Zn2+ binding. The induced-fitting of the Co-1 aptamer and the lock-and-key binding of Zn-1 aptamer may explain the general metal binding of the former. Using isothermal titration calorimetry, Co-1 binding Co2+ was an enthalpy-driven event and the Kd was determined to be 2.7 µM, whereas the Kd from the strand-displacement assay was 76 nM. The Co-1 aptamer is the first reported aptamer to follow the Irving-Williams series, although this series is very prevalent in proteins. This aptamer can thus serve as a model system for understanding metal binding by DNA and can also be a general first-row transition metal sensing element.

title: Selection of DNA Aptamers for Patulin, A Challenging Toxin in Fruit Products for Antibody Production

description: Dataset Description The dataset, named Selection of DNA Aptamers for Patulin, A Challenging Toxin in Fruit Products for Antibody Production. Contains raw and processed data from selection of DNA aptamers by capture-SELEX, DNA sequencing and analysis, Thioflavin T (ThT) fluorescence titration experiment, and isothermal titration calorimetry (ITC) experiments evaluating the binding interactions between DNA aptamers and a target small molecule patulin. Dataset Composition The dataset comprises 12 sheets in a .CSV file. After sequencing the PCR-amplified DNA products, Geneious-Prime software was used for family classification and conserved sequence analysis. The ThT fluorescence experiment included affinity measurement of aptamers, the effect of different salt ion concentrations on affinity, aptamer selectivity, and fluorescence quantification curves of patulin in fruit juice. ITC experiments include affinity measurements of aptamers and their mutants to targets. Data Collection and Processing Experiments were conducted between May 2024 and May 2025 at the Department of Chemistry, University of Waterloo, using a MicroCal 200-ITC instrument (Malvern Panalytical, UK). The aptamer was dissolved in MES-buffered saline (pH=6.0) and degassed prior to titration. The small molecule was dissolved in MES buffer at the desired concentration. All measurements were performed at 25 °C with an initial reference power of 10 μcal/s. Raw data were processed using Origin 8.0 software (OriginLab, USA) with baseline correction applied to remove instrument drift. Thermodynamic parameters were calculated via non-linear least squares fitting using a single-site binding model. The ThT fluorescence experiment was performed using HORIBA Scientific's FluoroMax-4 test and analyzed using FlourEssence V3.5. The amplicon sequencing we do for your labdone using the lllumina Miseq, usually with tV3 600 kit (2x300 bp). They are run at a small percentage ofthe runalong with the 16S amplicon sequencing frothe run's principal customer. We perform qPCR and run your pool on ourAgilent TapeStation to estimate size and theconcentration of your pool to determine theloading amount on the run. Data Format and Accessibility The dataset is provided in CSV format, accompanied by a README.txt file detailing the variable definitions, experimental setup, and data processing pipeline. Ethics and Compliance This study does not involve human or animal subjects. All data were generated in compliance with institutional research guidelines.

title: Microplastic characteristics in stormwater pond water

description: Microplastics (MPs), or plastic particles that are less than 5 mm in diameter, are an emerging threat to aquatic and terrestrial ecosystems because of their potential toxicity and their resistance to degradation. In urban watersheds, stormwater runoff is a major carrier of MPs to downstream water bodies, which often drains into green infrastructure such as stormwater ponds (SWPs). The existing evidence indicates that SWPs may be effective at reducing the export loads of MPs from urban areas. However, the effectiveness of SWPs in retaining MPs and the controls on their accumulation in SWPs remain understudied. To investigate MP occurrence and factors controlling MP distribution in the SWP water column, we collected water samples from five stormwater ponds with different land uses in their catchment area. Water samples were collected from the water column near the pond outlet for every month from February 2023 to December 2023. Microplastics were extracted from the samples and characterized using laser direct infrared imaging spectroscopy. Results and findings from the analysis of this data are reported in Controls on microplastic accumulation in stormwater pond water (pending submission, DOI: TBD).

title: Data for "A mixed methods study to explore the process of clinical reasoning employed by clinical students during primary clinical assessments"

description: This study employed a convergent mixed methods design (4), utilizing both quantitative and qualitative data to explore the clinical reasoning process used by final year medical and physician associate (PA) students during Single Best Answer (SBA) questions and Objective Structured Clinical Examinations (OSCE). These two groups were used as both have a medical model of education.To ensure the validity and expert grounding of the study questions, the research commenced with a Nominal Group Technique (NGT) consensus process (5). The NGT aimed to define the key questions that would form the basis of the quantitative Likert scale items and the qualitative focus group interviews, drawing upon the concept framework of clinical reasoning developed in the narrative review.An expert group of six members, including the primary researcher and an independent facilitator, was recruited aiming for a balance of views and institutional geography.The NGT was conducted remotely using online video conferencing and collaborative Google Sheets (6) for data gathering, ensuring anonymity during the initial silent question generation phase. Participants were provided with a condensed version of the narrative review, focusing on the concept framework, to ensure clarity of the underpinning ideas.During the question generation stage, 68 initial questions were put forward. These were grouped using agreed topic tags (table 1), based on the concept framework, which also served as the initial coding framework for thematic analysis. Following review and removal of duplicates, 41 questions proceeded to the ranking stage.The final output was a set of ten agreed questions (table 2). These questions were adapted slightly for the two arms of the study. The quantitative questions used a 10-point Likert scale (never–always), while the qualitative questions were open ended to promote further consideration of the concepts.Data collection was conducted across three different UK university sites to improve validity. The study targeted final year medical and physician associate (PA) students. Recruitment was via email invite from the local education teams and participation entirely voluntary.The quantitative component captured data contemporaneously with students undertaking SBA and OSCE assessments and then immediately answering the study questions using an online form completed on personal electronic devices under exam conditions.Qualitative Data Capture was via seven face-to-face focus groups across the three sites with transcripts produced by the researcher through immersion and editing of an initial automated transcript.The specific datasets are available her for additional analysis as apropriate.Ethics was granted by the University of Sheffield, reference 044729
