This theme presents observations of invasive exotic species (IAS)transmitted and validated using the Sentinelle tool, an EEE detection system.An invasive exotic species is a plant, animal or microorganism (virus,bacteria or fungi) that are introduced outside of their natural range. Sonestablishment or its spread may pose a threat to the environment,the economy or society. The species listed are species of fauna and floraconcerning (or potentially worrying) for Quebec's biodiversity. Ellesinclude EEE present in Quebec and EEE not listed in Quebec atmonitor.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The Shorezone Biobanding Polygons are an area representation of the various types of biota (flora and fauna) and their distribution, or lack thereof, found in the shoreunit.

The Shorezone Biobanding Lines are a linear representation of the various types of biota (flora and fauna) and their distribution, or lack thereof, found in the shoreunit.

The “Terrestrial Ecodistricts of Canada” dataset provides representations of ecodistricts. An ecodistrict is a subdivision of an ecoregion and is characterized by distinctive assemblages of relief, landforms, geology, soil, vegetation, water bodies and fauna. For example, the Jeddore Lake ecodistrict (no. 473) is one of five ecodistricts within the Maritime Barrens ecoregion.

The “Terrestrial Ecoregions of Canada” dataset provides representations of ecoregions. An ecoregion is a subdivision of an ecoprovince and is characterized by distinctive regional ecological factors, including climate, physiography, vegetation, soil, water, and fauna. For example, the Maritime Barrens ecoregion (no. 114) is one of nine ecoregions within the Newfoundland ecoprovince.

## #DescriptionThis database contains the coordinates of observations of fish and invertebrates, which are exotic and invasive, known by the Ministry of the Environment, the Fight against Climate Change, Wildlife and Parks (MELCCFP) in Quebec as of June 2025.An aquatic invasive species is a plant, animal, or microorganism (virus, bacteria, or fungus) that is introduced outside of its natural range, colonizes new sites or regions at a rapid rate, and can form dominant populations. Its establishment or spread can pose a threat to the environment, economy, or society.## #Les observations come from a variety of sources such as:* scientific sampling carried out by the MELCCFP and by other governmental or non-profit organizations;* mentions of citizens who contacted MELCCFP customer service directly or using tools such as Sentinelle and iNaturalist;* accidental catches by commercial fishermen who are members of the Saint Lawrence Network for the Early Detection of Exotic Aquatic Invasive Species.For more information on the control of aquatic invasive species, introduction factors, or prevention methods, consult the following web page: [Management of exotic invasive animal species] (https://www.quebec.ca/agriculture-environnement-et-ressources-naturelles/faune/gestion-faune-habitats-fauniques/gestion-especes-exotiques-envahissantes-animales).To help you identify the various species of freshwater fish in Quebec (native and invasive), use the iPêche mobile application (available [here] (https://www.quebec.ca/tourisme-et-loisirs/activites-sportives-et-de-plein-air/peche-sportive/identifier-poisson-ipeche)), which is free and developed by the Government of Quebec. This application allows voluntary reporting of catches for wildlife research purposes.## #Mises on guard* __Please consult the PDF document for the list of acronyms and references used in the “Invasive exotic aquatic fauna in Quebec” database . __* Data is not exhaustive. Thus, the absence of information in a given territory does not mean that there are no invasive aquatic fauna.* The observations transmitted by means of photographs are validated by experts, but have not all been subject to field validation by the MELCCFP.* The observations may have been changed since they were integrated into the database (e.g. control action).**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This dataset documents the infauna occurrences collected from 2021 to 2023 during the Canadian Beaufort Sea Marine Ecosystem Assessment (CBS-MEA) conducted by the Department of Fisheries and Oceans (DFO). This scientific program focuses on the integration of oceanography, food web linkages, physical-biological couplings, and spatial and interannual variabilities.The program also aims to expand the baseline coverage of species diversity, abundances, and habitat associations in previously unstudied areas of the Beaufort Sea and Western Canadian Archipelago. The study took place mainly in the Canadian Beaufort Sea and the Amundsen Gulf. Sampling is done along transects at fixed stations in the study area. Catches are collected using a 50 x 50 cm box-corer. 2 or 3 box core is collected per station to obtain replicates. A total of 29 stations were sampled for infauna in 2021, 15 in 2022 and 25 in 2023 between 10-653 m depth. Half of the box corer (0.125 m2) is sampled for infauna taxonomy. The first 20 cm of sediment are collected and sieved through a 0.5 mm mesh sieve. The samples are preserved in seawater-formaldehyde solution (10 % v/v). In the lab, infauna is identified to the lowest taxon level possible.The data are presented in two files:The "Activité_endofaune_CBSMEA_infauna_event_en" file which contains information about missions, stations and deployments, which are presented under a hierarchical activity structure.The "Occurrence_endofaune_CBSMEA_infauna_en" file that contains the taxonomic occurrences.

The purpose of the survey is to document and record habitat types and associated algae and marine invertebrate species in a variety of habitat types. Transect locations are randomly selected throughout the study area, which rotates between the north and south coasts of British Columbia on a biannual basis. Transects are laid perpendicular to the shoreline. A team of two divers swim the transect with data sheets to collect habitat, algae and marine invertebrate data as detailed below in the methods section. Data is keypunched in an MS Access database that can be queried for species observations and environmental information.This dataset includes three tables pulled from the original database containing observations by species, observations by quadrat, and additional header information for each observation. All three tables can be linked by the field HKey. Three lookup tables are included as well, one for algae, one for invertebrates, and one for substrates.
