The objective was to characterize succession of the community following a natural experiment in 2000-2001, when release of water from the lake, followed by a severe drought, reduced water levels by 2 m, alleviating stress of multiple years of high water. A systematic survey of shoreline transects was used to compare attributes of submerged plants under pre-drought versus post-drought conditions. Initially, the plants did not respond to lower water because shoreline areas had high turbidity from resuspended sediments and, later algal blooms. In June 2000, approximately 2 months after the water level was lowered, <i>Chara</i> (a macro-alga) rapidly expanded across the near-shore landscape. For over 1 year, this plant strongly dominated the submerged plant community, with just scattered individuals or isolated beds of vascular plants, including <i>Potamogeton, Vallisneria</i>, and <i>Hydrilla</i>. This included a period when the lake reached a record low elevation, where much of the habitat became dry, and then subsequently re-flooded in late summer 2001. However, in November 2001, <i>Chara</i> rapidly declined and vascular taxa (<i>Hydrilla</i> and <i>Potamogeton</i>) became dominant. They subsequently increased their biomass and spatial extent, and the previous <i></i> dominance did not return. Just prior to the loss of <i>Chara</i>, a frontal system passed over the lake, with wind velocities in excess of 30 km h<sup>-1</sup> for 3 days. Concentrations of solids in the water more than doubled and uprooted <i>Chara</i> was observed floating in the water. In this large, wind-driven lake, <i>Chara</i> may only be an ephemeral pioneer because, lacking roots, it is probably more sensitive to excessive wind-related stress (e.g. wave energy and scouring) than vascular plants.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Recovery of submerged plants from high water stress in a large subtropical lake in Florida, USA","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":"submerged plants; high water levels; wind; recovery; subtropical lakes;charophytes; angiosperms","OtherDescriptors":null,"Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2004-01-26","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000188210000006","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":56727,"PubliDate":2004,"Pagination":"67-82","XtraPublOfAnaID":null,"ISBN":null,"Volume":"78","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
