Isotopen zijn elementen met hetzelfde aantal protonen maar een verschillend aantal neutronen die niet vervallen in de tijd.<\/p>\n\n\n\n
Welnu, deze isotopenelementen zijn in verband gebracht met de bepaling van de voedingsbron van trekdieren.<\/p>\n\n\n\n
De lamellen van de ooglenzen zouden rijk zijn aan eiwitten. Deze eiwitten worden gebonden door isotopenelementen die leiden tot een isotopische signatuur die kan worden ge\u00ebvalueerd door middel van stabiele isotopenanalyse.<\/p>\n\n\n\n
De juveniele zalmvis werd bestudeerd in drie verschillende isotopische habitats met een verschillend voedselweb om het archiefweefsel van de oogbol van de vis te kwantificeren.<\/p>\n\n\n\n
De gebruikte stabiele isotoopelementen waren zwavel 35, koolstof 13 en stikstof 15 (34<\/sup>S, 13<\/sup>C,15<\/sup>N).<\/p>\n\n\n\nDe zwavelisotoop is nuttig om de voedingsbronnen te leren kennen. De vis van de kustmigratie is rijk aan koolstof-13-isotoop en wordt daarom gebruikt om de migratiebeweging te bepalen.<\/p>\n\n\n\n
De stikstofisotoop wordt gebruikt voor het besturen van de trofische niveaus bij trekdieren.<\/p>\n\n\n\n
De stabiele isotopenanalyse is geformuleerd op basis van het concept \"je bent wat je eet\".<\/p>\n\n\n\n
Op basis hiervan keken de wetenschappers naar isotopenelementen zoals zwavel, koolstof en stikstof in het weefsel van de volwassen zalmvis die in drie verschillende habitats werd gekweekt.<\/p>\n\n\n\n
Hun studie leidde tot de bevinding dat de in de seizoensgebonden uiterwaarden gekweekte vissen meer lagen van de lens hadden en ook veel sneller groeiden dan de in de rivier en in het broedhuis gekweekte vissen.<\/p>\n\n\n\n
Ook bleek uit de isotopenanalyse dat de vissen een hoog koolstof- en zwavelgehalte hadden als gevolg van de rijstvelden van de Bypass.<\/p>\n\n\n\n
De binding van de eiwitten van de oogbol en het isotoopelement werd gebruikt om het voedingsgehalte te analyseren.<\/p>\n\n\n\n
Bovendien werd bij de jonge zalmvis een stabiel isotopenelement in de oogbollens geregistreerd, wat leidde tot de vergelijking met de volwassen vis voor het overzicht van zijn habitat en voedingsbron.<\/p>\n\n\n\n
Dit instrument voor stabiele isotopenanalyse (SIA) heeft het toepassingsgebied voor diverse natuurbehoudsprojecten verruimd. Het kan worden gebruikt om habitats voor verschillende trekdieren te isoleren, aangezien deze sterk worden aangetast door de huidige klimaatveranderingen en ook door menselijke activiteiten.<\/p>\n\n\n\n
