Cook) Sojak, <i>Phragmites australis</i> (Cav.) Trin. ex Steud. and <i>Schoenoplectus validus</i> (Vahl) A. Love & D. Love. Five plant traits (total plant length, number of shoots, above-ground biomass, root and rhizome biomass, tuber biomass) were recorded in response to different treatments. Treatments included clipping frequency (i.e. clipped once or clipped every 7 days), clipping intensity (i.e. no clipping, 50% clipped and 100% clipped), and submersion treatments (water-depth of 0 and 10 cm). The general response of the three species to increased clipping frequency and intensity was a greater reduction in above-ground biomass, total plant length and the number of shoots produced. Almost no growth occurred in all three species when clipped 100% every 7 days. Clipping and water-depth treatments had no significant effect on root growth in all three species. Compared to the clipping treatments, the change in water-depth had less effect on the three species growth response. Only the number of shoots produced by <i>P. australis</i> was significantly reduced with increased water-depth. The removal of 50% of <i>S. validus</i> plant tissue grown in damp conditions (water-depth of 0 cm), however, did not reduce above-ground biomass.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Influences of simulated grazing and water-depth on the growth of juvenile <i>Bolboschoenus caldwellii</i>, <i>Phragmites australis</i> and <i>Schoenoplectus validus</i> plants","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"biomass; emergent macrophytes; growth response; clipping","OtherDescriptors":null,"Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2004-03-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000220269500003","VABBcode":null,"OpenAcc":1,"DOI":"10.1016/j.aquabot.2003.10.004"},"refs":null,"anarec":{"AnaID":58482,"PubliDate":2004,"Pagination":"233-242","XtraPublOfAnaID":null,"ISBN":null,"Volume":"78","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
