A higher diversity of primary producers often results in higher resource use efficiency in aquatic and terrestrial ecosystems. This may result in more food for consumers on one hand, while, on the other hand, it can also result in a decreased food quality for consumers; higher biomass combined with the same availability of the limiting compound directly reduces the dietary proportion of the limiting compound. Here we tested whether and how interspecific competition in phytoplankton communities leads to changes in resource use efficiency and cellular concentrations of nutrients and fatty acids. The measured particulate carbon\u200a:\u200aphosphorus ratios (C:P) and fatty acid concentrations in the communities were compared to the theoretically expected ratios and concentrations of measurements on simultaneously running monocultures. With interspecific competition, phytoplankton communities had higher concentrations of the monounsaturated fatty acid oleic acid and also much higher concentrations of the ecologically and physiologically relevant long\u2010chain polyunsaturated fatty acid eicosapentaenoic acid than expected concentrations based on monocultures. Such higher availability of essential fatty acids may contribute to the positive relationship between phytoplankton diversity and zooplankton growth, and may compensate limitations by mineral nutrients in higher trophic levels.<\/jats:p>","DOI":"10.1890\/14-1915.1","type":"journal-article","created":{"date-parts":[[2015,9,11]],"date-time":"2015-09-11T17:26:36Z","timestamp":1441992396000},"page":"2467-2477","source":"Crossref","is-referenced-by-count":16,"title":["Interspecific competition in phytoplankton drives the availability of essential mineral and biochemical nutrients"],"prefix":"10.1002","volume":"96","author":[{"given":"Alexander","family":"Wacker","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vanessa","family":"Marzetz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elly","family":"Spijkerman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2015,9]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/bit.25014"},{"key":"e_1_2_6_3_1","first-page":"1659","article-title":"Phosphorus limitation effects on the fatty acid content and nutritional quality of a green alga and a diatom","volume":"26","author":"Ahlgren","year":"1998","journal-title":"Verhandlungen der Internationalen Vereinigung f\u00fcr Theoretische und Angewandte Limnologie"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-0-387-89366-2_10"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1461-0248.2006.00963.x"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00387494"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2427.2010.02429.x"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.2041-210X.2011.00111.x"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature05202"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.biortech.2013.08.051"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0065-2881(03)46005-7"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.3354\/meps324113"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/fwb.12143"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.4319\/lo.2012.57.2.0554"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1890\/03-0095"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1461-0248.2006.00919.x"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0021972"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jembe.2008.11.009"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-0-387-89366-2_1"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1758-2229.2012.00366.x"},{"key":"e_1_2_6_21_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1461-0248.2011.01651.x"},{"key":"e_1_2_6_22_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0706.2011.20461.x"},{"key":"e_1_2_6_23_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.286.5442.1123"},{"key":"e_1_2_6_24_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1529-8817.1999.3520403.x"},{"key":"e_1_2_6_25_1","doi-asserted-by":"publisher","DOI":"10.1016\/0005-2728(87)90084-3"},{"key":"e_1_2_6_26_1","doi-asserted-by":"publisher","DOI":"10.1086\/285814"},{"key":"e_1_2_6_27_1","doi-asserted-by":"publisher","DOI":"10.1086\/282171"},{"key":"e_1_2_6_28_1","doi-asserted-by":"publisher","DOI":"10.1093\/plankt\/fbp015"},{"key":"e_1_2_6_29_1","doi-asserted-by":"publisher","DOI":"10.1515\/BOT.2004.050"},{"key":"e_1_2_6_30_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1399-3054.1999.100212.x"},{"key":"e_1_2_6_31_1","doi-asserted-by":"publisher","DOI":"10.3354\/meps08485"},{"key":"e_1_2_6_32_1","doi-asserted-by":"publisher","DOI":"10.4319\/lo.2004.49.4_part_2.1457"},{"key":"e_1_2_6_33_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2435.2011.01876.x"},{"key":"e_1_2_6_34_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1529-8817.2000.98251.x"},{"key":"e_1_2_6_35_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0031-9422(02)00215-7"},{"key":"e_1_2_6_36_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature02210"},{"key":"e_1_2_6_37_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-2670(00)88444-5"},{"key":"e_1_2_6_38_1","first-page":"7","article-title":"Growth media\u2014freshwater","author":"Nichols H.
