Starting with the PEMA-derived species list from barcodes, records are filtered to include only recognised invasive taxa. Each occurrence is enriched with the sampling coordinates associated with ARMS deployments, and all points are pooled across temporal and spatial datasets. The Geographic information service , Plot Trend Analysis offered by MyLifeWatch are then used to compute spatial metrics for each invasive taxon. Comparing successive timeframes reveals the direction and magnitude of range expansion. The outputs include maps that demonstrate newly occupied regions Jose Zaiño LifeWatch ERIC josea.zaino@lifewatch.eu 1.0.0 https://metadatacatalogue.lifewatch.eu/srv/api/records/2c6e37fc-0723-4edf-a48e-fad3bb4e7026/attachments/DNA-based%20trend%20in%20the%20distributional%20range%20of%20invasive%20taxa.png DNA-based trend in the distributional range of invasive taxa.png trend invasive species taxonomy PEMA DNA-based ARMS spatial analysis metabarcoding GPLv3 - <a href="https://www.gnu.org/licenses/gpl-3.0.html" target="_blank">https://www.gnu.org/licenses/gpl-3.0.html</a> https://my.lifewatch.eu/workflow/create-workflow-from-template/aneris-distributional WWW:LINK-1.0-http--link Link to the workflow PEMA Runner This service aims at running PEMA on all the sequences passed as input.
