The effects of this invasion on ecosystem processes are less well known. We examined decomposition of <i>L. salicaria</i> stems versus that of native <i>Typha latifolia</i> (broad-leaved cattail) in a previously cultivated, freshwater marsh in central New York State. We expected different decomposition rates and differences in litter quality of <i>L. salicaria</i> stems and <i>T. latifolia</i> shoots. We also quantified ergosterol concentration, an index of fungal biomass. However, standing-dead <i>T. latifolia</i> shoots and <i>L. salicaria</i> stems had lost similar quantities of mass (20-25%) after 1 year. Subsequent heavy snowfall and winter winds caused tissue fragmentation and much greater mass loss, but still similar for both plant species. Ergosterol concentrations were greater in <i>T. latifolia</i> shoots than in <i>L. salicaria</i> stems; yet, changes in tissue concentrations of nitrogen (N) and Klason lignin were very similar for both plant species. Therefore, although native <i>T. latifolia</i> may be more favorable in wetlands, the results of this study suggest that <i>L. salicaria</i> stems and <i>T. latifolia</i> shoots decompose in a similar fashion and have similar influence on the ecosystem-level processes measured in this study.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Early stages of decay of <i>Lythrum salicaria</i> L. and <i>Typha latifolia</i> L. in a standing-dead position","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":"decomposition; ergosterol; New York State; nitrogen; freshwater marsh","OtherDescriptors":null,"Notes":null,"AnaPub":2003,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2003-01-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000180605800005","VABBcode":null,"OpenAcc":1,"DOI":"10.1016/s0304-3770(02)00164-x"},"refs":null,"anarec":{"AnaID":31139,"PubliDate":2003,"Pagination":"45-57","XtraPublOfAnaID":null,"ISBN":null,"Volume":"75","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
