(2024) Contact:NicholasPontone@cmail.carleton.ca   Description:A map of peatland sub-classes (bog, poor fen, rich fen and permafrost peat complex) for the Canadian Boreal Forest circa 2020 created using a three-stage hierarchical classification framework. Training and validation data consisted of peatland locations derived from various sources (field data, aerial photo interpretation, measurements documented in literature). A combination of multispectral data, L-band SAR and C-Band interferometric SAR coherence, forest structure, and ancillary variables were used as model predictors. Ancillary data were used to mask agricultural areas and urban regions, and account for regions that may exhibit permafrost Pixel Values: 1: Bog2: Rich Fen3: Poor Fen4: Peatland Permafrost Complex5: Mineral Wetlands6: Water7: Upands8: Agriculture9: Urban Recommended Colours 1: 4C00732: FFFF003: E64C004: 7272725: F4C2C26: 0070FF7: 4C73008: 6231319: 000000   Please cite as: Pontone, N., Millard, K., Thompson, D.K., Guindon, L. and Beaudoin, A.

Renato 2024-10-04 This dataset refers to: Area, volume and ELA changes of West Greenland local glaciers and ice caps over the last 35 yearsSecuro Andrea, Del Gobbo Costanza, Citterio Michele, Machguth Horst, Marcer Marco, Korsgaard Niels J., Colucci Renato R. This study analyses the cumulative area, ice mass and Equilibrium Line Altitude changes that occurred on more than 4000 glaciers and ice caps in West Greenland (outside of the Greenland Ice Sheet) from 1985 to 2020, using remotely sensed data and including glaciers smaller than 1 km2 in the calculations.

Naranjo-Orrico, Domenica; Ovaskainen, Otso; Furneaux, Brendan; Purhonen, Jenna; Arancibia, Paulina A.; Burg, Skylar; Moser, Niklas; Niku, Jenni; Tikhonov, Gleb; Zakharov, Evgeny; Monkhouse, Norman; Abrego, Nerea 2024-06-10 Data and scripts for reproducing the analyses of Naranjo-Orrico et al Wind is a primary driver of fungal dispersal across a mainland-island system.  The file allData.RData contains the data in R format. The data include three matrices: the metadata (md), the sample x OTU table (otu.table) and the taxonomic information of the identified OTUs (taxonomy). These three files need to be loaded using the function load in R for reproducing the statistical analyses performed in the study. The statistical analyses consist of joint species distribution modelling with the package Hmsc. To perform the analyses the three scripts need to be run consecutively from S1 to S3. S1 defines and fits the 12 models fitted in the study (which include both presence-absence and abundance models, with different variants with a different set of explanatory variables). S2 shows the parameter estimates from the fitted models, in particular the beta parameters and the variance partitioning across environmental covariates. S3 builds the predictions on species richness and community weighted spore traits in relation to the focal environmental predictors. https://creativecommons.org/licenses/by/4.0/legalcode

BIOSCAN-5M is a comprehensive dataset containing multi-modal information for over 5 million insect specimens, and it significantly expands existing image-based biological datasets by including taxonomic labels, raw nucleotide barcode sequences, assigned barcode index numbers, geographical information, and specimen size. Every record has both image and DNA data. Each record of the BIOSCAN-5M dataset contains six primary attributes: RGB image DNA barcode sequence Barcode Index Number (BIN) Biological taxonomic classification Geographical information Specimen size Additional BIOSCAN-5M dataset-related packages are accessible through the GoogleDrive folder including: BIOSCAN_5M_original_full: The raw images of the dataset. BIOSCAN_5M_cropped: Images after cropping with our cropping tool introduced in BIOSCAN-1M. BIOSCAN_5M_original_256: Original images resized to 256 on their shorter side. https://creativecommons.org/licenses/by/3.0/legalcode

Yeung, Jonas; DeYoung, Taylor; Spring, Shoshana; de Guzman, A. Elizabeth; Elder, Madeline W.; Wong, Shun C.; Palmert, Mark R.; P. Lerch, Jason; Nieman, Brian J. 2024-02-13 Description Biological sex influences prevalence of developmental disorders through sex hormones and sex chromosomes. However, our understanding of their impacts in neurodevelopment and response to injury remains limited. In this project, we use high resolution magnetic resonance imaging (MRI) to investigate the four core genotype mouse model (FCG) that separates the influences of sex hormones and sex chromosomes during normal brain development and after cranial radiation therapy.  Sex differences are attributed to either sex hormones or sex chromosomes. This can be distinguished by the FCG model which decouples the sex determining region (SRY) from the Y chromosome by moving SRY onto an autosome. This gives us four core sex genotypes: XX NULL, XY NULL, XX SRY, and XY SRY. This dataset represents the most comprehensive mouse brain imaging study employing the FCG model to date with 5 timepoints (P14, P23, P42, P63, P98), Ccl2 wildtype (+/+) and knockouts (-/-), irradiation (7Gy) and sham (0Gy) mice. All in all, a total of 1071 images! The results presented here is published in PNAS. In vivo MRI scans were obtained using a 7-T MRI scanner (Bruker BioSpin, Ettlingen, Germany) equipped with four cryocoils for simultaneous imaging of four mice. The scans were performed with the following settings: T1-weighted, 3D-gradient echo sequence, 75μm isotropic resolution, TR=26ms, TE=8.25ms, flip angle=26°, field of view=25×22×22mm, and matrix size=334×294×294. All structural MR images are stored in images.tar.gz. Images were segmented and registered using an automated pipeline which are stored in labels.tar.gz. The consensus average and labels are final_average.mnc and final_labels.mnc, respectively. Extracted structure volumes alongside the metadata are included in df_micevolumes.csv. Structural MRIs are in MINC format and the readme.txt provides further information on this dataset.  The authors express their sincere gratitude for the research funding recieved from the Canadian Institutes of Health Research (158622, 168037) and the Ontario Institute for Cancer Research (IA-024) with funding from the Government of Ontario and Restracomp from the SIckKids Research Training Centre.
