Stable isotope ratios of N15/N14 showed that the food web in each estuary contained three trophic levels, while the C13/C12 ratio enabled differentiation of the food chains based on detrital material and plankton. Fatty acid data revealed trophic markers for dinoflagellates in A.\u00a0butcheri and L. wallacei and for diatoms in P. olorum. \nThese findings suggest that:\n1) the food resources are partitioned within and among species, \n2) the dietary compositions differ between estuaries and \n3) different sources of organic material support pelagic and benthic food chains", "num_resources": 2, "num_tags": 6, "organization": {"id": "0143757a-86ab-43e4-bba6-4a3a2a02b6c4", "name": "australian-ocean-data-network", "title": "Australian Ocean Data Network", "type": "organization", "description": "Harvester for Australian Ocean Data Network", "image_url": "", "created": "2025-06-23T12:29:10.320926", "is_organization": true, "approval_status": "approved", "state": "active"}, "original_harvest_source": {"site_url": "https://catalogue.aodn.org.au", "href": "https://catalogue.aodn.org.au/geonetwork/srv/eng/csw/dataset/wamsi-node-4-3-1b-trophic-interactions-in-selected-south-western-australian-estuaries-phd", "title": "Australian Oceans Data Network"}, "owner_org": "0143757a-86ab-43e4-bba6-4a3a2a02b6c4", "private": false, "promotion_level": "0", "spatial": "{\"type\": \"Polygon\", \"coordinates\": [[[115.75, -32.1], [116.0, -32.1], [116.0, -31.85], [115.75, -31.85], [115.75, -32.1]]]}", "spatial_coverage": "{\"type\": \"Polygon\", \"coordinates\": [[[115.75, -32.1], [116.0, -32.1], [116.0, -31.85], [115.75, -31.85], [115.75, -32.1]]]}", "state": "active", "temporal_coverage_from": "2017-11-21 18:11:45", "title": "WAMSI Node 4.3.1b - Trophic interactions in selected south-western Australian estuaries - PhD", "type": "dataset", "unpublished": false, "url": null, "version": null, "extras": [{"key": "harvest_object_id", "value": "d8a718a0-e490-48ad-92a1-a749871de92f"}, {"key": "harvest_source_id", "value": "a2216e59-91ec-48b1-83cc-d35d9f09fcec"}, {"key": "harvest_source_title", "value": "Australian Oceans Data Network"}], "resources": [{"cache_last_updated": null, "cache_url": null, "created": "2025-06-23T10:38:44.196762", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "License Graphic", "format": "PNG", "hash": "", "id": "c6937a82-f907-4be9-8228-5a1f831a1487", "last_modified": null, "metadata_modified": "2025-06-23T10:38:44.177248", "mimetype": null, "mimetype_inner": null, "name": "Unnamed resource", "package_id": "35929e1e-85b7-4014-a76f-ed12ec3d1e80", "position": 0, "resource_locator_function": "", "resource_locator_protocol": "WWW:LINK-1.0-http--related", "resource_type": null, "size": null, "state": "active", "url": "http://i.creativecommons.org/l/by-nc-sa/2.5/au/88x31.png", "url_type": null, "zip_extract": false}, {"cache_last_updated": null, "cache_url": null, "created": "2025-06-23T10:38:44.196768", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "", "format": "HTML", "hash": "", "id": "7eae2843-b7d9-4831-befe-dc2a36c1d5c2", "last_modified": null, "metadata_modified": "2025-06-23T10:38:44.177399", "mimetype": null, "mimetype_inner": null, "name": "Unnamed resource", "package_id": "35929e1e-85b7-4014-a76f-ed12ec3d1e80", "position": 1, "resource_locator_function": "", "resource_locator_protocol": "WWW:LINK-1.0-http--related", "resource_type": null, "size": null, "state": "active", "url": "http://creativecommons.org/international/au/", "url_type": null, "zip_extract": false}], "tags": [{"display_name": "Biosphere | Aquatic Habitat | Estuarine Habitat", "id": "19d7f191-074e-436c-8eed-c361d2d7c407", "name": "Biosphere | Aquatic Habitat | Estuarine Habitat", "state": "active", "vocabulary_id": null}, {"display_name": "Biosphere | Ecological Dynamics | Food-web Dynamics", "id": "f20a6010-0a7d-4cf7-94d5-a8b7404f8e8d", "name": "Biosphere | Ecological Dynamics | Food-web Dynamics", "state": "active", "vocabulary_id": null}, {"display_name": "Biosphere | Ecological Dynamics | Trophic Dynamics", "id": "9799825e-6f9b-4b22-b1d9-df3313e38de9", "name": "Biosphere | Ecological Dynamics | Trophic Dynamics", "state": "active", "vocabulary_id": null}, {"display_name": "Diet", "id": "47cda0f3-89db-4ce7-9722-8bd0e1447efa", "name": "Diet", "state": "active", "vocabulary_id": null}, {"display_name": "Fatty Acids", "id": "df2a6723-1b66-46e0-8f3c-723544d3f386", "name": "Fatty Acids", "state": "active", "vocabulary_id": null}, {"display_name": "Stable Isotopes", "id": "ddacd8ec-2109-4189-9b83-c3aac7566d39", "name": "Stable Isotopes", "state": "active", "vocabulary_id": null}], "groups": [], "relationships_as_subject": [], "relationships_as_object": []}}
