Supplementary to the research of Hummel et al. (1985) the influence of 2, 4, 6 and 8 days of emersion in different seasons on the survival of some benthic intertidal species was investigated. Partly on the ground of the results of this research (high mortality among benthic animals) the scedule for the April 1987 use was changed. Investigation of the new scedule showed far less damage. The other two investigated scedules showed little damage. With regard to the effect of emersion the investigated species could be divided into 5 groups: 1). Very sensitive to emersion almost the year round: <i>Diadumene cincta, Tharyx marioni , Nephtys hombergii</i> and <i>Scoloplos armiger</i> . 2). Sensitive to longer periods of emersion throughout the year: <i>Pygospio elegans, Sagartia troglodytes</i>, juvenile <i>Nereis diversicolor</i>, juvenile <i>Macoma balthica</i> and <i>Heteromastus filiformis</i>. 3).Sensitive to longer periods of emersion in spring and summer: adult <i>M.balthica, Cerastoderma edule , Mytilus edulis and Arenicola marina</i>. 4). Only sensitive at extreme (high) temperatures: <i>Hydrobia ulvae</i>, adult <i>Nereis diversicolor</i> and <i>Ostrea edulis</i>. 5). Not sensitive to emersion: <i>Littorina littorea</i>. In general 2 days of emersion only caused little damage among benthic intertidal animals, especially in the 0 to 10°C temperature interval. Longer periods of emersion in the 0 to 20°C temperature interval caused a considerable mortality, whereas higher or lower temperatures were fatal to the benthic fauna.","AbstractOtherLang":"In het kader van project AFWERK werd het effect van een aantal sluitingsscenario's van de stormvloedkering in de Oosterschelde, te gebruiken ten behoeve van het plaatsen van de dorpelbalken (juli 1986) en de sluiting van het Tholensche Gat (september 1986) en de Krammer (april 1987), op de overleving van bodemdieren onderzocht. Aanvullend op het BARCON onderzoek van Hummel et al. (1985) werd in verschillende seizoenen het effect van 2,4,6 en 8 dagen droogstand op de overleving van een aantal bodemdiersoorten onderzocht. Mede op grond van de resultaten van dit onderzoek (veel sterfte onder bodemdieren) werd het bij de afsluiting van de Krammer te gebruiken scenario bijgesteld. Onderzoek van dit nieuwe scenario leverde aanzienlijk minder schade op. De schade van de twee andere onderzochte scenario's was eveneens beperkt. Op grond van het onderzoek naar het effect van droogstand konden de onderzochte soorten in 5 groepen worden onderverdeeld: 1). Vrijwel altijd erg gevoelig: <i>Diadumene cincta</i>, <i>Tharyx marioni</i>, <i>Nephtys hombergii</i> en <i>Scoloplos armiger</i>. 2). Een groot deel van het jaar gevoelig voor langere periodes van droogstand: <i>Pygospio elegans , Sagartia troglodytes</i> , kleine <i>Nereis diversicolor</i> , kleine <i>Macoma balthica</i> en <i>Heteromastus filiformis</i>. 3). Vooral in het voorjaar en de zomer gevoelig voor langere periodes van droogstand: grote <i>Macoma balthica, Cerastoderma edule, Mytilus edulis</i> en <i>Arenicola marina</i>. 4). Alleen gevoelig bij extreme (hoge) temperaturen: <i>Hydrobia ulvae</i>, grote <i>Nereis diversicolor</i> en <i>Ostrea edulis</i>. 5). Altijd ongevoelig: <i>Littorina littorea</i>. Algemeen kan gesteld worden, dat 2 dagen droogstand, vooral bij temperaturen tussen 0 en 10°C, weinig schade toebrengt aan de bodemdieren, Een langere droogstand bij temperaturen tussen 0 en 20°C zal echter een vrij aanzienlijke sterfte tot gevolg hebben, terwijl hogere en lagere temperaturen dan zeer schadelijk zijn.","BibLvlCode":"MS","StandardTitle":"Het gebruik van de stormvloedkering bij de afbouwwerkzaamheden in de Oosterschelde: effecten van een aantal sluitingsscenario's op bodemdieren","OrigTitleLangCode":"nl","OrigTitleLangCodeExtended":"dut","OrigTitleLangID":41,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":1989,"DateUpdate":"2003-11-14","DateCreate":"2003-10-13","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":null,"monrec":{"MonID":40697,"ISBN":null,"PubliDate":1989,"IssueDate":null,"Volume":"2","Issue":null,"Pagination":"79","Place":"Yerseke","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":63390,"SerRR":"DIHO Rapporten en verslagen.
