One important connection is the export of biomass by emergent aquatic insects containing omega-3 polyunsaturated fatty acids (PUFAs), especially eicosapentaenoic acid (EPA), that is scarce in terrestrial systems. Because of taxon-specific differences in PUFA content and functional traits, the contribution of different insect groups should be considered, in addition to total biomass export. In this context, one important trait is the emergence mode. Stoneflies, in contrast to other aquatic insects, crawl to land to emerge instead of flying directly from the water surface, making them accessible to ground-dwelling predators. Because stoneflies are especially susceptible to environmental change, stream degradation might cause a mismatch of available and required nutrients, particularly for ground-dwelling predators. In this study, we estimated emergent biomass and EPA export along two streams with different levels of habitat degradation. The EPA content in aquatic insects did not differ with different degrees of habitat degradation and total biomass export in spring was with 7.9 ± 9.6 mg m-2 day-1 in the degraded and 7.3 ± 8.5 mg m-2 day-1 in the natural system, also unaffected. However, habitat degradation substantially altered the contribution of crawling emergence to the total export in spring, with no biomass export by stoneflies at the most degraded sites. The EPA content in ground-dwelling spiders was correlated with emergent stonefly biomass, making up only 16.0 ± 6.2 \% of total fatty acids at sites with no stonefly emergence, but 27.3 ± 3.0 \% at sites with highest stonefly emergence. Because immune function in ground-dwelling spiders has been connected to EPA levels, reduced crawling emergence might impact spider fitness. Functional traits, like emergence mode as well as nutritional quality, should be considered when assessing the effects of stream degradation on adjacent terrestrial ecosystems.}, language = {en} } @misc{FehlingerMathieuResugePileckyetal., author = {Fehlinger, Lena and Mathieu-Resuge, Margaux and Pilecky, Matthias and Parmar, Tarn Preet and Twining, Cornelia W. and Martin-Creuzburg, Dominik}, title = {Export of dietary lipids via emergent insects from eutrophic fishponds}, series = {Hydrobiologia}, volume = {Vol. 850}, journal = {Hydrobiologia}, number = {15}, issn = {1573-5117}, doi = {10.1007/s10750-022-05040-2}, pages = {3241 -- 3256}, language = {en} } @misc{ParmarKindingerMathieuResugeetal., author = {Parmar, Tarn Preet and Kindinger, Alina L. and Mathieu-Resuge, Margaux and Martin-Creuzburg, Dominik}, title = {Fatty acid composition differs between emergent aquatic and terrestrial insects - A detailed single system approach}, series = {Frontiers in Ecology and Evolution}, journal = {Frontiers in Ecology and Evolution}, issn = {2296-701X}, doi = {10.3389/fevo.2022.952292}, pages = {1 -- 13}, language = {en} } @misc{PileckyKaemmerMathieuResugeetal., author = {Pilecky, Matthias and K{\"a}mmer, Samuel K. and Mathieu-Resuge, Margaux and Wassenaar, Leonard I. and Taipale, Sami J. and Martin-Creuzburg, Dominik}, title = {Hydrogen isotopes (δ2H) of polyunsaturated fatty acids track bioconversion by zooplankton}, series = {Functional Ecology}, volume = {36}, journal = {Functional Ecology}, number = {3}, issn = {1365-2435}, doi = {10.1111/1365-2435.13981}, pages = {538 -- 549}, language = {en} } @misc{IsantaNavarroKlauschiesWackeretal., author = {Isanta-Navarro, Jana and Klauschies, Toni and Wacker, Alexander and Martin-Creuzburg, Dominik}, title = {A sterol-mediated gleaner-opportunist trade-off underlies the evolution of grazer resistance to cyanobacteria}, series = {Proceedings of the Royal Society : Series B, Biological sciences}, volume = {289}, journal = {Proceedings of the Royal Society : Series B, Biological sciences}, number = {1974}, issn = {1471-2954}, doi = {10.1098/rspb.2022.0178}, language = {en} } @misc{LaineMartinCreuzburgLitmanenetal., author = {Laine, Miikka Benjami and Martin-Creuzburg, Dominik and Litmanen, Jaakko J. and Taipale, Sami J.}, title = {Sterol limitation of Daphnia on eukaryotic phytoplankton: A combined supplementation and compound-specific stable isotope labeling approach}, series = {Oikos}, journal = {Oikos}, issn = {1600-0706}, doi = {10.1111/oik.10359}, pages = {1 -- 14}, language = {en} } @misc{RiehleBeachMultrusetal., author = {Riehle, Eva and Beach, Daniel G. and Multrus, Selina and Parmar, Tarn Preet and Martin-Creuzburg, Dominik and Dietrich, Daniel R.}, title = {Fate of Planktothrix-derived toxins in aquatic food webs: A case study in Lake Mindelsee (Germany)}, series = {Ecotoxicology and Environmental Safety}, volume = {273}, journal = {Ecotoxicology and Environmental Safety}, issn = {1090-2414}, doi = {10.1016/j.ecoenv.2024.116154}, pages = {1 -- 13}, language = {en} } @misc{KieneWackerMartinCreuzburg, author = {Kiene, Marvin and Wacker, Alexander and Martin-Creuzburg, Dominik}, title = {Omega-3 versus Omega-6: Are We Underestimating the Ecological Significance of Arachidonic Acid in Aquatic Systems?}, series = {Biomolecules}, volume = {13}, journal = {Biomolecules}, number = {5}, issn = {2218-273X}, doi = {10.3390/biom13050791}, abstract = {The long-chain polyunsaturated fatty acids (PUFA) eicosapentaenoic acid (EPA, ω-3, or n-3) and arachidonic acid (ARA, ω-6 or n-6) are known to have distinct physiological functions, yet can both support growth and reproduction of consumers, raising the question of whether EPA and ARA are ecologically substitutable dietary resources. We explored the relative importance of EPA and ARA for the growth and reproduction of the freshwater keystone herbivore Daphnia in a life-history experiment. Both PUFA were supplemented in a concentration-dependent manner to a PUFA-free diet, separately and in combination (50\% EPA: 50\% ARA mixture). The growth-response curves obtained with EPA, ARA, and the mixture were virtually congruent and the thresholds for PUFA limitation did not differ, indicating that EPA (n-3) and ARA (n-6) were substitutable dietary resources under the applied experimental conditions. The actual requirements for EPA and ARA might change with growth conditions, e.g., under the influence of parasites or pathogens. The higher retention of ARA in Daphnia suggests that EPA and ARA are subject to different turnover rates, which also implies different physiological functions. Studies on the ARA requirements of Daphnia could provide valuable information on the presumably underestimated ecological importance of ARA in freshwater food webs.}, language = {en} }
