Isotopes are elements that have the same number of protons but a different number of neutrons that don’t decay over time.<\/p>\n\n\n\n
N\u00e5 har disse isotopene blitt brukt til \u00e5 bestemme n\u00e6ringsgrunnlaget til vandrende dyr.<\/p>\n\n\n\n
Lamellene i \u00f8yeeplets linser sies \u00e5 v\u00e6re rike p\u00e5 proteiner. Disse proteinene er bundet av isotopiske elementer som f\u00f8rer til en isotopisk signatur som kan evalueres gjennom analyse av stabile isotoper.<\/p>\n\n\n\n
Den unge laksefisken ble studert i tre ulike isotopiske habitater med ulike n\u00e6ringsnett for \u00e5 kvantifisere det arkiverte vevet i fiske\u00f8yet.<\/p>\n\n\n\n
De stabile isotopene som ble brukt, var svovel 35, karbon 13 og nitrogen 15 (34<\/sup>S, 13<\/sup>C,15<\/sup>N).<\/p>\n\n\n\nSvovelisotopen er nyttig for \u00e5 finne ut hva fisken har spist. Fisk fra kystvandring er rik p\u00e5 karbon-13-isotoper, og brukes derfor til \u00e5 bestemme vandringen.<\/p>\n\n\n\n
Nitrogenisotopen brukes i styringen av de trofiske niv\u00e5ene hos vandrende dyr.<\/p>\n\n\n\n
The stable isotope analysis is formulated on the basis of the “you are what you eat\u201d concept.<\/p>\n\n\n\n
P\u00e5 bakgrunn av dette har forskerne sett etter isotoper av grunnstoffer som svovel, karbon og nitrogen i vevet til voksen laksefisk som har vokst i tre ulike habitater.<\/p>\n\n\n\n
Unders\u00f8kelsen f\u00f8rte til at fisken som ble dyrket i den sesongbaserte flomsletten, hadde flere linselag og vokste mye raskere enn fisken som vokste i elven og klekkeriet.<\/p>\n\n\n\n
Isotopanalysen viste ogs\u00e5 at fiskene hadde et h\u00f8yt innhold av karbon og svovel p\u00e5 grunn av rismarkene i omkj\u00f8ringsveien.<\/p>\n\n\n\n
Bindingen av proteinet i fiskekulene og isotopelementet ble brukt til \u00e5 analysere innholdet i dietten.<\/p>\n\n\n\n
I tillegg til dette ble det registrert stabile isotopelementer i \u00f8yelinsen p\u00e5 lakseyngelen, noe som gjorde det mulig \u00e5 sammenligne den med voksen fisk for \u00e5 f\u00e5 oversikt over habitat og n\u00e6ringskilde.<\/p>\n\n\n\n
Dette verkt\u00f8yet for analyse av stabile isotoper (SIA) har utvidet mulighetene for ulike bevaringsprosjekter. Det kan brukes til \u00e5 isolere leveomr\u00e5der for ulike migrerende dyr, siden de er sterkt p\u00e5virket av dagens klimaendringer og menneskelige aktiviteter.<\/p>\n\n\n\n
