Since a diatom is known to contain more abundant long\u2010chain poly unsaturated fatty acids (<jats:styled-content style=\"fixed-case\">PUFA<\/jats:styled-content>s), we hypothesized that the diatom\u2010consuming <jats:italic>D.\u00a0magna<\/jats:italic> would exhibit more successful reproduction rates. Upon the hypothesis, we designed three experiments using two algal species, a green alga (<jats:italic>Chlorella vulgaris<\/jats:italic>) and a diatom (<jats:italic>Stephanodiscus hantzschii<\/jats:italic>). From the results, we found that the mating frequency and copulation duration increased in the treatment with <jats:italic>S.\u00a0hantzschii<\/jats:italic>, resulting in a significant increase of hatching rates of resting eggs. In the other two repetitive mating strategies (e.g., one female vs. multiple males, and one male vs. multiple females), we found that the hatching rates of resting eggs were greater in the <jats:italic>S.\u00a0hantzschii<\/jats:italic> treatment. In addition to the mating strategy, male body size significantly increased in the diatom treatment, hence average diameter of penis was also statistically different among the treatments (greater diameter in the <jats:italic>S.\u00a0hantzschii<\/jats:italic> treatment). To examine the effect of algal food quality, we estimated quantity of fatty acids in the two algal species. Our result showed that <jats:italic>S.\u00a0hantzschii<\/jats:italic> had a higher proportion of long\u2010chain <jats:styled-content style=\"fixed-case\">PUFA<\/jats:styled-content>s than <jats:italic>C.\u00a0vulgaris<\/jats:italic>. Furthermore, a stable isotope analysis revealed that carbon and nitrogen originated from <jats:italic>S.\u00a0hantzschii<\/jats:italic> were more assimilated to <jats:italic>D.\u00a0magna<\/jats:italic>. In summary, our study manifested that diatom consumption of <jats:italic>D.\u00a0magna<\/jats:italic> leads to more successful sexual reproduction. We then discussed how the diatom consumption of zooplankton influences food web dynamics in a freshwater ecosystem.<\/jats:p>","DOI":"10.1002\/ece3.2058","type":"journal-article","created":{"date-parts":[[2016,3,22]],"date-time":"2016-03-22T08:51:25Z","timestamp":1458636685000},"page":"2817-2832","source":"Crossref","is-referenced-by-count":16,"title":["Effects of algal food quality on sexual reproduction of <i><scp>D<\/scp>aphnia magna<\/i>"],"prefix":"10.1002","volume":"6","author":[{"given":"Jong\u2010Yun","family":"Choi","sequence":"first","affiliation":[{"name":"National Institute of Ecology Seo\u2010Cheon Gun Chungcheongnam Province 325\u2010813 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seong\u2010Ki","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences Pusan National University Busan 609\u2010735 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Geung\u2010Hwan","family":"La","sequence":"additional","affiliation":[{"name":"Department of Environmental Education Sunchon National University Sunchon 540\u2010742 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kwang\u2010Hyeon","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Environmental Engineering Kyung\u2010Hee University Yongin 446\u2010701 Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong\u2010Kyun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Physical &amp;
