Integrave Taxonomy: a New Tool for Fisheries Conservaon Adela Roa-Varon and Eric Hilton Virginia InsFtute of Marine Science, William & Mary College [email protected], [email protected] What is Integrave Taxonomy? The Process of Integrave Results to Date Glossary Taxonomy Baits libraries were designed based on Species play a central role in nearly all candidate single-copy markers for disciplines of biology. Therefore delimitaon Gadus morhua genome, using the Species are the fundamental of species has broad implicaons for efforts taxonomic unit for a wide array of MYBaits target enrichment system. A biological studies and applied fields ranging from biological conservaon to preliminary analysis was run to test the such as conservaon planning. comparave evoluFonary analyses. The rise of baits using Merluccius bilinearis and new genomic and bioinformacs tools led for Gadus morhua as a posiFve control.
