Short-term (28 d) lab experiments indicated that the intrinsic rate of increase (<em>r</em>) and carrying capacity (<em>K</em>) of the marine diatom <em>Seminavis robusta</em> decreased with increasing atrazine exposure. This decrease did not show the concave shape expected from the lifetime productivity for nonexposed diatoms and from single-species toxicity data in the literature but instead was described best by a linear model. These experimentally observed atrazine-induced decreases of <em>r</em> and <em>K</em> were used to parameterize a Rosenzweig-MacArthur model representing a simple food chain including the tested diatom and its grazer, the harpacticoid copepod <em>Delavalia palustris</em> var. <em>palustris</em>. Stable oscillation zoo-phytobenthos systems were produced at diatom exposures of 0, 100, and 150?µg/L atrazine. An atrazine concentration of 150?µg/L contributed to a 15% increase of the oscillation periods of both diatoms and copepods as well as a 52% reduction of oscillation amplitudes compared with the control situation. Although the amplitudes of copepods increased only 7% at 150?µg/L atrazine, the maximum and minimum copepod densities at that concentration were reduced 61 and 63%, respectively. The effects of atrazine on periodicity and amplitudes were robust to 20% changes in the food-chain model parameters that represented allometric relationships. The simulations in the present study suggest food chain–mediated indirect effects on zoobenthos populations, indicating a reduced diatom and copepod availability throughout the year.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Modeling toxic stress by atrazine in a marine consumer-resource system","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-19 01:31:34.060891","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Intrinsic rate of increase; Rosenzweig-MacArthur model; Consumer resource","OtherDescriptors":null,"Notes":null,"AnaPub":2013,"MonPub":null,"DateUpdate":"2016-07-04","DateCreate":"2013-05-13","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000317852700016","VABBcode":null,"OpenAcc":0,"DOI":"10.1002/etc.2160"},"refs":null,"anarec":{"AnaID":225374,"PubliDate":2013,"Pagination":"1088-1095","XtraPublOfAnaID":null,"ISBN":null,"Volume":"32","Issue":"5","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42839,"SerRR":"Environmental Toxicology and Chemistry.
