This data contains the current caribou subpopulation (herd) boundaries. Herd boundaries are derived from the best available science and expert knowledge. A caribou subpopulation (herd) boundary is the area required to be managed to achieve a self-sustaining population. Subpopulation boundaries do not overlap even though some caribou subpopulations share portions of their annual range. *This dataset is the focal point of the Caribou in British Columbia - Web Application.

Effective conservation planning relies on understanding population connectivity which can be informed by genomic data. This is particularly important for sessile species like the horse mussel (Modiolus modiolus), a key habitat-forming species and conservation priority in Atlantic Canada), yet little genomic information is available to describe horse mussel connectivity patterns. We used more than 8000 restriction-site associated DNA sequencing-derived single nucleotide polymorphisms and a panel of 8 microsatellites to examine genomic connectivity among horse mussel populations in the Bay of Fundy, along the Scotian Shelf, and in the broader northwestern Atlantic extending to Newfoundland. Despite phenotypic differences between sampling locations, we found an overall lack of genetic diversity and population structure in horse mussels in the Northwest Atlantic Ocean. All sampled locations had low heterozygosity, very low FST, elevated inbreeding coefficients, and deviated from Hardy-Weinberg Equilibrium, highlighting generally low genetic diversity across all metrics. Principal components analysis, Admixture analysis, pairwise FST calculations, and analysis of outlier loci (potentially under selection) all showed no independent genomic clusters within the data, and an analysis of molecular variance showed that less than 1% of the variation within the SNP dataset was found between sampling locations. Our results suggest that connectivity is high among horse mussel populations in the Northwest Atlantic, and coupled with large effective population sizes, this has resulted in minimal genomic divergence across the region. These results can inform conservation design considerations in the Bay of Fundy and support further integration into the broader regional conservation network.Cite this data as: Van Wyngaarden, Mallory et al.

A spatial representation of the general distribution of wild mountain sheep (bighorn and thinhorn sheep) in British Columbia. Populations that extend into neighbouring provinces and states are also included. The distribution polygons are divided by species into bighorn and thinhorn sheep.

## #Description of the distribution areas of local populations of woodland caribou, forest ecotype, in QuebecThe data represent the distribution areas of 13 local populations and two areas of knowledge acquisition for woodland caribou, a forest ecotype in Quebec (hereinafter forest caribou).The file contains the polygons and the name assigned to each population or knowledge acquisition sector, the period covered by the telemetry data used during the delimitation exercise, and the date these boundaries were last updated. The information contained in the file of occurrences of species in a precarious situation of the Quebec Natural Heritage Data Center (CDPNQ) is also present in the file (CDPNQ occurrence number, French, English and scientific name of the species, the type of occurrence, the rank of precariousness [rank S] and the status under the Act Respecting Threatened or Vulnerable Species, see MELCCFP 2023 for a description of these fields.).## #ContexteThe Ministry of the Environment, the Fight against Climate Change, Wildlife and Parks (hereinafter MELCCFP) is responsible for the monitoring and management of forest caribou in Quebec (Government of Quebec, 2021 a). In 2017-2018, the MELCCFP improved its monitoring activities in order to obtain an accurate and up-to-date portrait of the situation of the various populations on its territory (see [Literature review on the factors involved in the decline of caribou populations in Quebec, Government of Quebec] (https://consultation.quebec.ca/rails/active_storage/blobs/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaHBjZz09IiwiZXhwIjpudWxsLCJwdXIiOiJibG9iX2lkIn19--45f10ff67d1f9e80ca714b08f984b5965760abd3/RevueLitterature_CaribouVF.pdf), 2021 b). The local population has been identified as the appropriate monitoring and management scale for this species since each population may face different threats depending on the habitat and socio-economic context in which it is found (Environment Canada, 2008). It is within this framework that the work to identify and delimit the distribution areas of forest caribou populations carried out in 2021-2022 is part of. The local population is defined as a group of caribou occupying a defined territory that is spatially distinct from the territories occupied by other caribou groups. The dynamics of the local population are determined primarily by local factors influencing birth and mortality rates, rather than by the contributions or losses resulting from immigration or emigration between groups. Therefore, the ranges of local forest caribou populations in this file are defined as the geographic area where a group of individuals exposed to similar factors influencing their demographics live and which meets the needs of their life cycle over a given period of time (e.g. calving, rutting, wintering). Note that for the two knowledge acquisition sectors, Baie-James and Matamec, the number of caribou monitored and the temporal scale of monitoring do not allow to date clearly conclude that they are distinct local populations or to associate these caribou with an adjacent population.## #Méthodologie in a nutshellThe forest caribou populations in Charlevoix and Val-d'Or were excluded from the following manipulations, as their geographic isolation is sufficient to demonstrate that they are local populations distinct from other caribou groups. A minimal convex polygon was made using 100% of telemetry data from 2004-2012 and 2017-2021 for the population of Charlevoix and from 1986 to 2020 for that of Val-d'Or.For other forest caribou populations, telemetry data from collars placed on caribou by the MELCCFP and various partners (Université Laval, Université du Québec à Rimouski, Hydro-Québec, Government of Ontario and Government of Ontario and Government of Newfoundland and Labrador) were used to identify and delimit the distribution areas of local populations. The data ranges from 2001 to 2021, but the period covered by the data varies by sector of study (see field: Layer tempo for information). Forest caribou populations in Quebec were identified by assigning caribou monitored by telemetry to a population using the fuzzy classification method (*c-mean fuzzy clustering*; Schaefer et al., 2001; Schaefer et al., 2001; Schaefer and Wilson, 2002). This method aims to unite individuals into groups in order to maximize the distance between members of distinct groups and to minimize the distance between members of the same group. Centroids from individual home ranges were used in this analysis. The ranges were delineated by creating minimal convex polygons including 100% of caribou locations (100% MCP) assigned to a population. For the Baie-James sector, the area was delimited by removing the overlaps between the area inventoried in 2020 (Szor and Gingras, 2020) and the distribution areas of the surrounding local populations. For the Matamec sector, the area represents the non-overlap between the distribution area of the local population of the Lower North Shore and a minimum convex polygon encompassing all telemetry data for caribou in the Matamec sector and the local Lower North Shore population. The acquisition of knowledge on the distribution of caribou and the presence of distinct populations continues in the Baie-James sector (Nord-du-Québec) and the Matamec sector (Côte-Nord). The last update was made in 2021-2022.## #Mise in custody and data use limits:* The distribution areas of forest caribou populations in Quebec in this file represent the state of knowledge on the use of land by caribou between 2001 and 2021. * Information on the ranges of local populations does not make it possible to establish with certainty that caribou are absent in territories outside the ranges. * Distribution areas represent areas where caribou belonging to the same population are likely to be found. They do not make it possible to identify the sectors used more or less strongly by caribou in this population or the sectors used by caribou to move within the range or from one population to another (connectivity sectors).* The ranges are subject to change, depending on the new telemetry data that will be acquired, the refinement of our local knowledge and the changes in the patterns of land use by caribou. ## #LittératureEnvironment Canada. 2008.

A global decline in seagrass populations has led to renewed calls for their conservation as important providers of biogenic and foraging habitat, shoreline stabilization, and carbon storage. Eelgrass (Zostera marina) occupies the largest geographic range among seagrass species spanning a commensurately broad spectrum of environmental conditions. In Canada, eelgrass is managed as a single phylogroup despite occurring across three oceans and a range of ocean temperatures and salinity gradients. Previous research has focused on applying relatively few markers to reveal population structure of eelgrass, whereas a whole genome approach is warranted to investigate cryptic structure among populations inhabiting different ocean basins and localized environmental conditions. We used a pooled whole-genome re-sequencing approach to characterize population structure, gene flow, and environmental associations of 23 eelgrass populations ranging from the Northeast United States, to Atlantic, subarctic, and Pacific Canada. We identified over 500,000 SNPs, which when mapped to a chromosome-level genome assembly revealed six broad clades of eelgrass across the study area, with pairwise FST ranging from 0 among neighbouring populations to 0.54 between Pacific and Atlantic coasts. Genetic diversity was highest in the Pacific and lowest in the subarctic, consistent with colonization of the Arctic and Atlantic oceans from the Pacific less than 300 kya. Using redundancy analyses and two climate change projection scenarios, we found that subarctic populations are predicted to be more vulnerable to climate change through genomic offset predictions. Conservation planning in Canada should thus ensure that representative populations from each identified clade are included within a national network so that latent genetic diversity is protected, and gene flow is maintained. Northern populations, in particular, may require additional mitigation measures given their potential susceptibility to a rapidly changing climate.Cite this data as: Jeffery, Nicholas et al. (2024).

Shows areas where the health and prevalence of caribou can be linked to the attributes of the land that supports them. Ontario's Woodland Caribou Recovery Strategy (2008) provides advice and recommendations on the approaches needed for the recovery of Woodland Caribou. The strategy recommends the identification of ranges and local populations to: * maintain existing, self-sustaining, genetically-connected local populations of caribou * ensure security for and (reproductive) connections among currently isolated mainland caribou * re-establish caribou in strategic areas to create self-sustaining local populations and ensure connectivity Instructions for downloading this dataset: * select the link below and scroll down the metadata record page until you find **Transfer Options** in the **Distribution Information** section, * select the link beside the **Data for download** label, * you must provide your name, organization and email address in order to access the dataset This product requires the use of GIS software. *[GIS]: geographic information system

The Indigenous Populations of Canada map is derived from the CanEcumene 2.0 Geodatabase using custom tabulations of census-based population data. Indigenous communities within the level of the census sub-division (CSD) were identified using a combination of sources from census field data (see Eddy et. al. 2020 for more details). This map shows the percent of Indigenous population in CanEcumene 2.0 communities using graduated symbols, overlaid upon a population density raster. The larger the symbol, the higher the percentage of Indigenous population in that area. The darker the colour in the underlying raster, the denser is the general population. This map illustrates how the majority of Indigenous populations reside in locations outside of the denser populated areas of Canada.

Municipalities with established populations of _Ixodes scapularis_ ticks (blacklegged ticks) are municipalities where tick populations reproduce and survive from one year to the next. This indicator makes it possible to identify municipalities where their presence suggests a higher risk of tick bites and the transmission of diseases, such as Lyme disease, anaplasmosis or babesiosis. In other municipalities without an established population, the presence of ticks is possible, as ticks can be carried there by birds or terrestrial mammals. The data used to build this indicator come from passive and active acarological surveillance. Active and passive surveillance data were accumulated and then aggregated by municipality and by year. This made it possible to determine whether an established tick population is identified by the indicator at least 1 year over the study period.The climate zone favorable to the establishment of ticks _Ixodes scapularis_ highlights the areas where the estimated temperature would be favorable to the establishment of tick populations in Quebec. An area where the climate is favorable for the establishment of tick populations is defined by an annual number of degree-days above 0°C (DJ0). This indicator was calculated for the historical surveys 2009-2017 (current distribution) and for the horizons of 2030, 2050 and 2080 according to the climate scenarios SSP2-4.5 and SSP3-7.0 (future distribution). The DJ0 are calculated by calculating the difference between the daily mean temperature and the 0°C reference temperature used in this situation, then interpolating on a 10km x 10km grid. The final DJ0 value used is the 50th percentile.For more information on municipalities with established populations of _Ixodes scapularis_ ticks or the climatic zones favorable to their establishment you can consult the * [Methodological Report] (https://www.inspq.qc.ca/publications/3483) * OR the * [INSPQ website, Current and future distribution maps of zoonoses in Quebec] (https://www.inspq.qc.ca/zoonoses/cartes) *.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
