Izotopi so elementi, ki imajo enako \u0161tevilo protonov, vendar razli\u010dno \u0161tevilo nevtronov, ki s\u010dasoma ne razpadejo.<\/p>\n\n\n\n
Ti izotopi elementov so bili povezani z dolo\u010danjem prehranskega vira migrantskih \u017eivali.<\/p>\n\n\n\n
Lamele o\u010desnih le\u010d naj bi bile bogate z beljakovinami. Na te beljakovine se ve\u017eejo izotopski elementi, ki povzro\u010dijo izotopski podpis, ki ga je mogo\u010de oceniti z analizo stabilnih izotopov.<\/p>\n\n\n\n
Mladice lososa so preu\u010devali v treh razli\u010dnih izotopskih habitatih z razli\u010dnim prehranskim spletom, da bi dolo\u010dili koli\u010dino arhivskega tkiva o\u010desnega zrkla.<\/p>\n\n\n\n
Uporabljeni stabilni izotopi so bili \u017eveplo 35, ogljik 13 in du\u0161ik 15 (34<\/sup>S, 13<\/sup>C,15<\/sup>N).<\/p>\n\n\n\nIzotop \u017evepla je uporaben pri ugotavljanju prehranskih virov. Ribe iz obalne migracije imajo veliko izotopa ogljika 13, zato se uporablja za ugotavljanje selitvenega gibanja.<\/p>\n\n\n\n
Izotop du\u0161ika se uporablja pri dolo\u010danju trofi\u010dnih ravni pri migratornih \u017eivalih.<\/p>\n\n\n\n
Analiza stabilnih izotopov temelji na konceptu \"ste to, kar jeste\".<\/p>\n\n\n\n
Na podlagi tega so znanstveniki v tkivih odraslih lososov, ki so rasli v treh razli\u010dnih habitatih, iskali izotope elementov, kot so \u017eveplo, ogljik in du\u0161ik.<\/p>\n\n\n\n
Njihova \u0161tudija je pokazala, da so imele ribe, ki so rasle na sezonskem poplavnem obmo\u010dju, ve\u010d plasti le\u010de in so rasle hitreje kot ribe, ki so rasle v re\u010dnem okolju in v valilnici.<\/p>\n\n\n\n
Izotopska analiza je tudi pokazala, da imajo ribe zaradi ri\u017eevih polj ob obvoznici visoko vsebnost ogljika in \u017evepla.<\/p>\n\n\n\n
Za analizo vsebnosti prehrane je bila uporabljena vezava beljakovin ribje krogle in izotopskega elementa.<\/p>\n\n\n\n
Poleg tega je bil v o\u010desni le\u010di mladi\u010dev lososa zabele\u017een element stabilnega izotopa, kar je omogo\u010dilo primerjavo z odraslimi ribami za pregled njihovega habitata in prehranskega vira.<\/p>\n\n\n\n
To orodje za analizo stabilnih izotopov (SIA) je raz\u0161irilo podro\u010dje uporabe pri razli\u010dnih projektih ohranjanja. Uporablja se lahko za izlo\u010danje habitatov razli\u010dnih selitvenih \u017eivali, saj so te zelo prizadete zaradi sedanjih podnebnih sprememb in tudi zaradi \u010dlovekovih dejavnosti.<\/p>\n\n\n\n
