Monet metallit ovat vesieli\u00f6ille hivenaineina v\u00e4ltt\u00e4m\u00e4tt\u00f6mi\u00e4, mutta tiettyjen raja-arvojen ylittyminen aiheuttaa mm. lis\u00e4\u00e4ntymisongelmia ja kuolleisuuden kasvua.

T\u00e4ss\u00e4 tutkimuksessa seeprakaloja (Danio rerio) altistettiin m\u00e4timunista asti kaivosteollisuudessa k\u00e4ytetylle mangaanisulfaatille (MnSO4). K\u00e4sittelyj\u00e4 oli kolme (kontrolli, Mn 0,5 ja 3,5 mg/l). Tutkittuja k\u00e4ytt\u00e4ytymisvasteita olivat kalojen aktiivisuus, viive hakea ravintoa veden pinnalta sek\u00e4 pintak\u00e4yntien kokonaism\u00e4\u00e4r\u00e4.

Tutkitut kalat olivat per\u00e4isin kahdesta kokeellisesta valintalinjasta, joita on jalostettu iso- ja pienikokoisiksi. Isokokoisten kalojen odotettiin olevan aktiivisempia ja hakevan ravintoa innokkaimmin altistusolosuhteissa. Kaikissa k\u00e4sittelyiss\u00e4 isokokoisten linja osoittautui pienikokoisten linjaa aktiivisemmaksi, mutta MnSO4-pitoisuudella ei havaittu yhteytt\u00e4 aktiivisuuteen. Isokokoiset kalat k\u00e4viv\u00e4t pinnassa hakemassa ravintoa pienikokoisia nopeammin ja useammin. Pintak\u00e4yntien hajonta isokokoisten ryhm\u00e4ss\u00e4 kasvoi pitoisuuden noustessa. Tulosten perusteella kalojen k\u00e4ytt\u00e4ytyminen riippuu p\u00e4\u00e4asiassa populaatioiden v\u00e4lisist\u00e4 eroista, mutta havaittu yhteys pintasy\u00f6miskertojen ja MnSO4-pitoisuuden v\u00e4lill\u00e4 viittaa kohonneiden pitoisuuksien voivan vaikuttaa eri tavoin erilaisten populaatioiden ravinnonhankintak\u00e4ytt\u00e4ytymiseen.", "language": "fi", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2020-06-30T10:24:50Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-06-30T10:24:50Z (GMT).
