They are transferred to higher trophic levels and accumulated in food chains. However, LC-PUFA accumulation in consumers and their trophic transfer vary with the diet quality and the physiological demand for LC-PUFA of consumers. The goal of this study was to investigate spatial and taxonomic differences in LC-PUFA retention of coastal fish predators that potentially differ in their habitat use (benthic versus pelagic) and prey quality. We analyzed the fatty acid (FA) composition of common fish species, namely roach and European perch, as well as their potential prey from benthic and pelagic habitats in three bays of the northern Baltic Sea. We then assessed whether the fish LC-PUFA retention differed between species and among the study bays with different diet quality, that is, LC-PUFA availability. Our data indicated taxon-specific differences in the retention of LC-PUFA and their precursor FA in fish (i.e., short-chain PUFA with <20 carbon atoms). Perch did not show any spatial variation in the retention of all these FA, while roach showed spatial differences in the retention of docosahexaenoic acid (DHA) and their precursor FA, but not eicosapentaenoic acid (EPA). Data suggest that diet quality and trophic reliance on benthic prey underlay the DHA retention differences in roach. Although the PUFA supply might differ among sites, the low spatial variation in LC-PUFA content of perch and roach indicates that both fishes were able to selectively retain dietary LC-PUFA. Climate change together with other existing human-caused environmental stressors are expected to alter the algal assemblages and lower their LC-PUFA supply for aquatic food webs. Our findings imply that these stressors will pose heterogeneous impacts on different fish predators. We advocate further investigations on how environmental changes would affect the nutritional quality of the basal trophic level, and their subsequent impacts on LC-PUFA retention, trophic ecology, and performance of individual fish species.", "doi": "10.1002/ece3.10158", "pmid": "37274152", "labels": {"Swedish Metabolomics Centre": "Service"}, "xrefs": [{"db": "pmc", "key": "PMC10234757"}, {"db": "pii", "key": "ECE310158"}], "notes": [], "created": "2023-08-30T07:04:25.673Z", "modified": "2025-10-17T13:03:13.901Z"}, {"entity": "publication", "iuid": "90a0402f78a544d5b9b27e33ae213691", "links": {"self": {"href": "https://publications.scilifelab.se/publication/90a0402f78a544d5b9b27e33ae213691.json"}, "display": {"href": "https://publications.scilifelab.se/publication/90a0402f78a544d5b9b27e33ae213691"}}, "title": "Lowered nutritional quality of plankton caused by global environmental changes.", "authors": [{"family": "Lau", "given": "Danny C P", "initials": "DCP", "orcid": "0000-0002-3246-7508", "researcher": {"href": "https://publications.scilifelab.se/researcher/28aa8ed05fc64662b9a72cf4bde0e59b.json"}}, {"family": "Jonsson", "given": "Anders", "initials": "A", "orcid": "0000-0002-0807-0201", "researcher": {"href": "https://publications.scilifelab.se/researcher/d9585469c3f4439680f0ce4a70019106.json"}}, {"family": "Isles", "given": "Peter D F", "initials": "PDF", "orcid": "0000-0003-4446-6788", "researcher": {"href": "https://publications.scilifelab.se/researcher/e93e08c76b234c3e923cd4af6fa190a6.json"}}, {"family": "Creed", "given": "Irena F", "initials": "IF", "orcid": "0000-0001-8199-1472", "researcher": {"href": "https://publications.scilifelab.se/researcher/52a6eb00971f476c8d029750f62fba2e.json"}}, {"family": "Bergstr\u00f6m", "given": "Ann-Kristin", "initials": "AK", "orcid": "0000-0001-5102-4289", "researcher": {"href": "https://publications.scilifelab.se/researcher/ce35e85a593145c3b278e275792d8590.json"}}], "type": "journal article", "published": "2021-12-00", "journal": {"title": "Glob Chang Biol", "issn": "1365-2486", "volume": "27", "issue": "23", "pages": "6294-6306", "issn-l": "1354-1013"}, "abstract": "Global environmental changes are causing widespread nutrient depletion, declines in the ratio of dissolved inorganic nitrogen (N) to total phosphorus (DIN:TP), and increases in both water temperature and terrestrial colored dissolved organic carbon (DOC) concentration (browning) in high-latitude northern lakes. Declining lake DIN:TP, warming, and browning alter the nutrient limitation regime and biomass of phytoplankton, but how these stressors together affect the nutritional quality in terms of polyunsaturated fatty acid (PUFA) contents of the pelagic food web components remains unknown. We assessed the fatty acid compositions of seston and zooplankton in 33 lakes across south-to-north and boreal-to-subarctic gradients in Sweden. Data showed higher lake DIN:TP in the south than in the north, and that boreal lakes were warmer and browner than subarctic lakes. Lake DIN:TP strongly affected the PUFA contents-especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)-in seston, calanoids, and copepods (as a group), but not in cladocerans. The EPA+DHA contents increased by 123% in seston, 197% in calanoids, and 230% in copepods across a lake molar DIN:TP gradient from 0.17 to 14.53, indicating lower seston and copepod nutritional quality in the more N-limited lakes (those with lower DIN:TP). Water temperature affected EPA+DHA contents of zooplankton, especially cladocerans, but not seston. Cladoceran EPA+DHA contents were reduced by ca. 6% for every 1\u00b0C increase in surface water. Also, the EPA, DHA, or EPA+DHA contents of Bosmina, cyclopoids, and copepods increased in lakes with higher DOC concentrations or aromaticity. Our findings indicate that zooplankton food quality for higher consumers will decrease with warming alone (for cladocerans) or in combination with declining lake DIN:TP (for copepods), but impacts of these stressors are moderated by lake browning.
