The structure of these communities is shaped by environmental gradients, species features, and tolerance to competition\u2010related stressors. While laboratory studies show allelopathic potential of these primary producers, field\u2010based evidence integrating chemical interactions with environmental gradients is still poorly understood. We conducted a two\u2010season field study in eutrophic Lake Oporzy\u0144skie to assess the relative importance of allelopathy and environmental gradients in regulating community dynamics of\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>C. glomerata<\/jats:italic>\n                    <\/jats:styled-content>\n                    and\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>L. minor<\/jats:italic>\n                    <\/jats:styled-content>\n                    . We measured the phenolic content in water and species extracts, physicochemical water parameters and mat size, analyzing the associations using RDA, variance partitioning, and GAM. Variance partitioning showed that phenolics and physicochemical parameters jointly explained more variation in mat size (adjusted\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    \u2009=\u20090.446) than either fraction alone, with phenolics contributing a markedly larger unique fraction (\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    \u2009=\u20090.337) than physicochemical parameters (\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    \u2009=\u20090.060). RDA identified phenolic content in water as the strongest predictor of mat size, with an asymmetric relationship, positive for\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>C. glomerata<\/jats:italic>\n                    <\/jats:styled-content>\n                    and negative for\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>L. minor<\/jats:italic>\n                    <\/jats:styled-content>\n                    , consistent with an allelopathic advantage for the macroalga, which also had higher phenolic content in its own extract. GAM analyses confirmed this pattern and revealed contrasting, taxon\u2010specific response curves to phenolic content, pH, dissolved oxygen, and TDS. This was associated with temporal niche partitioning, with\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>C. glomerata<\/jats:italic>\n                    <\/jats:styled-content>\n                    dominating mid\u2010summer and\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>L. minor<\/jats:italic>\n                    <\/jats:styled-content>\n                    expanding in late summer and autumn. Our findings suggest that coexistence of these species reflects the combined action of allelopathic interactions and environmental gradients generating species\u2010specific temporal windows of dominance. This integrated approach highlights the need to jointly consider chemical and environmental drivers when studying plant community dynamics in aquatic ecosystems.\n                  <\/jats:p>","DOI":"10.1002\/ece3.74213","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T06:27:32Z","timestamp":1787812052000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["What Drives Seasonal Mat Dynamics in Eutrophic Lake: Allelopathy or Environmental Gradients?"],"prefix":"10.1002","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2493-7650","authenticated-orcid":false,"given":"Gosty\u0144ska","family":"Julia","sequence":"first","affiliation":[{"name":"Department of Hydrobiology, Faculty of Biology Adam Mickiewicz University  Pozna\u0144 Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G\u0105bka","family":"Maciej","sequence":"additional","affiliation":[{"name":"Department of Hydrobiology, Faculty of Biology Adam Mickiewicz University  Pozna\u0144 Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pankiewicz","family":"Rados\u0142aw","sequence":"additional","affiliation":[{"name":"Department of Environmental Physicochemistry, Faculty of Chemistry Adam Mickiewicz University  Pozna\u0144 Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Messyasz","family":"Beata","sequence":"additional","affiliation":[{"name":"Department of Hydrobiology, Faculty of Biology Adam Mickiewicz University  Pozna\u0144 Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,26]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.envc.2023.100733"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/ieam.4916"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aquabot.2012.05.007"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10750\u2010009\u20100074\u20105"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00027\u2010010\u20100162\u20107"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1890\/1051\u20100761(2002)012[1496:CIOANA]2.0.CO;2"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/0304\u20103770(86)90031\u20108"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10530\u2010019\u201002185\u20105"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/0043\u20101354(91)90110\u2010C"},{"key":"e_1_2_11_11_1","unstructured":"Dray S.
