We mimicked these conditions by taking undisturbed sediment ('before dredging' treatment) and by using restored sediment where the uppermost nutrient rich top layer was removed ('after dredging' treatment). Both the species were allowed to grow for seven weeks in monocultures and mixed cultures at different planting densities. Overall, invasive <i>L. major</i> performed better than native <i>C. demersum</i> independent of the characteristics of the growth environment. <i>L. major</i> achieved a higher relative growth rate (RGR) in both treatments based on total length (0.17-0.21 week<sup>-1</sup>) and weight (0.10-0.19 week<sup>-1</sup>) compared to <i>C. demersum</i> (length: 0.04-0.07 week<sup>-1</sup>; weight: 0.03-0.17 week<sup>-1</sup>). The better performance of <i>L. major</i> was due to a high plasticity under stressful conditions of low free CO<sub>2</sub> and high pH. Intraspecific competition and niche partitioning were observed between the two species indicating that species coexistence is favoured instead of competitive exclusion. <i>L. major</i> performed better in the 'after dredging' treatment. Consequently, we deduce that sediment dredging will not lead to a decline of the invasive <i>L. major</i>.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Competitive abilities of invasive <i>Lagarosiphon major</i> and native <i>Ceratophyllum demersum</i> in monocultures and mixed cultures in relation to experimental sediment dredging","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Invasive species; Relative growth rate; Competition; Aquatic vegetation management; Aquatic ecosystem; Sediment dredging","OtherDescriptors":null,"Notes":null,"AnaPub":2011,"MonPub":null,"DateUpdate":"2015-11-06","DateCreate":"2011-12-22","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000293480700013","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.aquabot.2011.05.011"},"refs":null,"anarec":{"AnaID":210662,"PubliDate":2011,"Pagination":"161-166","XtraPublOfAnaID":null,"ISBN":null,"Volume":"95","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
