Os is\u00f3topos s\u00e3o elementos que t\u00eam o mesmo n\u00famero de pr\u00f3tons, mas um n\u00famero diferente de n\u00eautrons que n\u00e3o se decomp\u00f5em com o tempo.<\/p>\n\n\n\n
Agora, estes is\u00f3topos foram associados \u00e0 determina\u00e7\u00e3o da fonte alimentar dos animais migrat\u00f3rios.<\/p>\n\n\n\n
Diz-se que as laminas das lentes de globo ocular s\u00e3o ricas em prote\u00ednas. Estas prote\u00ednas s\u00e3o ligadas por elementos isot\u00f3picos que levam a uma assinatura isot\u00f3pica que pode ser avaliada atrav\u00e9s de an\u00e1lise isot\u00f3pica est\u00e1vel.<\/p>\n\n\n\n
Os peixes juvenis de salm\u00e3o foram estudados sob tr\u00eas diferentes habitats isot\u00f3picos com uma teia alimentar diferente para quantificar o tecido de arquivo do globo ocular do peixe.<\/p>\n\n\n\n
Os elementos isot\u00f3picos est\u00e1veis utilizados foram o enxofre 35, o carbono 13 e o nitrog\u00eanio 15 (34<\/sup>S, 13<\/sup>C,15<\/sup>N).<\/p>\n\n\n\nO is\u00f3topo de enxofre \u00e9 \u00fatil na aprendizagem de fontes diet\u00e9ticas. O peixe da migra\u00e7\u00e3o costeira \u00e9 rico em is\u00f3topo de carbono 13 e por isso \u00e9 usado para determinar o movimento migrat\u00f3rio.<\/p>\n\n\n\n
O is\u00f3topo de nitrog\u00eanio \u00e9 utilizado no governo dos n\u00edveis tr\u00f3ficos em animais migrat\u00f3rios.<\/p>\n\n\n\n
A an\u00e1lise isot\u00f3pica est\u00e1vel \u00e9 formulada com base no conceito \"voc\u00ea \u00e9 o que voc\u00ea come\".<\/p>\n\n\n\n
Nesta base, os cientistas buscaram elementos isot\u00f3picos como enxofre, carbono e nitrog\u00eanio nos tecidos dos peixes adultos de salm\u00e3o cultivados em tr\u00eas variantes de habitats.<\/p>\n\n\n\n
Seu estudo levou \u00e0 descoberta de que os peixes cultivados na plan\u00edcie de inunda\u00e7\u00e3o sazonal tinham mais camadas da lente, al\u00e9m de crescerem muito mais rapidamente do que os cultivados no habitat do rio e da incubadora.<\/p>\n\n\n\n
Al\u00e9m disso, a an\u00e1lise de is\u00f3topos revelou que os peixes tinham um alto teor de carbono e enxofre devido aos campos de arroz do Bypass.<\/p>\n\n\n\n
A liga\u00e7\u00e3o das prote\u00ednas da bola de peixe olho e o elemento isot\u00f3pico foi usado para analisar o conte\u00fado da dieta.<\/p>\n\n\n\n
Al\u00e9m disso, os peixes juvenis de salm\u00e3o tinham um elemento isot\u00f3pico est\u00e1vel registrado em suas lentes oculares, o que levou \u00e0 compara\u00e7\u00e3o com os peixes adultos para a vis\u00e3o geral de seu habitat e fonte alimentar.<\/p>\n\n\n\n
Esta ferramenta de an\u00e1lise isot\u00f3pica est\u00e1vel (SIA) ampliou o escopo de v\u00e1rios projetos de conserva\u00e7\u00e3o. Ela poderia ser usada para isolar habitats de v\u00e1rios animais migrat\u00f3rios, j\u00e1 que eles s\u00e3o altamente afetados devido \u00e0s mudan\u00e7as clim\u00e1ticas atuais e tamb\u00e9m devido \u00e0s atividades humanas.<\/p>\n\n\n\n
