{"cited_by_count":1163134,"description":"This cluster of papers explores the ecological impact of crayfish invasions on freshwater ecosystems, focusing on biodiversity loss, physiological adaptation, DNA barcoding for identification, and conservation challenges. It also delves into the global distribution and predation effects of invasive crayfish species.","display_name":"Crustacean biology and ecology","domain_id":"3","external_ids":{"openalex":"https://openalex.org/T11004","wikipedia":"https://en.wikipedia.org/wiki/Impacts_of_invasive_crayfish_on_freshwater_ecosystems"},"field_id":"23","id":"T11004","keywords":[{"display_name":"Decapoda","id":"decapoda","score":0.7291,"url":"https://openalex.org/keywords/decapoda"},{"display_name":"Crustacea","id":"crustaceans","score":0.4492,"url":"https://openalex.org/keywords/crustaceans"},{"display_name":"Brachyura","id":"brachyura","score":0.6669,"url":"https://openalex.org/keywords/brachyura"},{"display_name":"Isopoda","id":"isopods","score":0.5433,"url":"https://openalex.org/keywords/isopods"},{"display_name":"terrestrial isopods","id":"terrestrial-isopods","score":0.6399,"url":"https://openalex.org/keywords/terrestrial-isopods"},{"display_name":"Amphipoda","id":"amphipods","score":0.3644,"url":"https://openalex.org/keywords/amphipods"},{"display_name":"hermit crabs","id":"hermit-crabs","score":0.836,"url":"https://openalex.org/keywords/hermit-crabs"},{"display_name":"Ostracoda","id":"ostracoda","score":0.2748,"url":"https://openalex.org/keywords/ostracoda"},{"display_name":"snapping shrimp","id":"snapping-shrimp","score":0.844,"url":"https://openalex.org/keywords/snapping-shrimp"},{"display_name":"Palaemonidae","id":"palaemonidae","score":0.8619,"url":"https://openalex.org/keywords/palaemonidae"},{"display_name":"shrimp","id":"shrimp","score":0.3774,"url":"https://openalex.org/keywords/shrimp"},{"display_name":"Paguridae","id":"paguridae","score":0.9736,"url":"https://openalex.org/keywords/paguridae"},{"display_name":"crabs","id":"crabs","score":0.4393,"url":"https://openalex.org/keywords/crabs"},{"display_name":"freshwater crustaceans","id":"freshwater-crustaceans","score":0.7311,"url":"https://openalex.org/keywords/freshwater-crustaceans"},{"display_name":"crab taxonomy","id":"crab-taxonomy","score":0.6874,"url":"https://openalex.org/keywords/crab-taxonomy"},{"display_name":"marine crustaceans","id":"marine-crustaceans","score":0.4568,"url":"https://openalex.org/keywords/marine-crustaceans"},{"display_name":"Cladocera","id":"cladocera","score":0.3151,"url":"https://openalex.org/keywords/cladocera"},{"display_name":"freshwater crabs","id":"freshwater-crabs","score":0.7123,"url":"https://openalex.org/keywords/freshwater-crabs"},{"display_name":"Anomura","id":"anomura","score":0.8642,"url":"https://openalex.org/keywords/anomura"},{"display_name":"pereopods","id":"pereopods","score":0.5452,"url":"https://openalex.org/keywords/pereopods"},{"display_name":"maxilliped","id":"maxilliped","score":0.5471,"url":"https://openalex.org/keywords/maxilliped"},{"display_name":"Gammaridae","id":"gammaridae","score":0.7845,"url":"https://openalex.org/keywords/gammaridae"},{"display_name":"swimming crab","id":"portunus-trituberculatus","score":0.652,"url":"https://openalex.org/keywords/portunus-trituberculatus"},{"display_name":"carapace","id":"carapace","score":0.4161,"url":"https://openalex.org/keywords/carapace"},{"display_name":"freshwater prawn","id":"freshwater-prawn","score":0.7173,"url":"https://openalex.org/keywords/freshwater-prawn"}],"legacy_keywords":["Crayfish","Invasion","Freshwater","Biodiversity","Ecological Impact","DNA Barcoding","Conservation","Physiological Adaptation","Predation","Global Distribution"],"openalex_id":"https://openalex.org/T11004","source_created_date":"2024-01-23T15:27:09","source_updated_date":"2026-10-17T03:02:00","subfield_id":"2303","url":"/topics/T11004","works_api_url":"https://api.openalex.org/works?filter=topics.id:T11004","works_count":327113,"label":"Crustacean biology and ecology","provider":"openalex","revision":"5b6767d8a8603960","taxonomy_revision":"f050b5d4780b1289","title":"Crustacean biology and ecology","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"36240456443416183","address_version":"morton4x16-v1","coordinates":[3,23,2303,11004],"answer_status":"Directory metadata; local answer requires separate source review","truth_status":"Subject descriptor, not a factual answer or a demonstrated knowledge gap","reviewed_answer":null}
