Los is\u00f3topos son elementos que tienen el mismo n\u00famero de protones pero un n\u00famero diferente de neutrones que no decaen con el tiempo.<\/p>\n\n\n\n
Ahora, estos elementos isot\u00f3picos se han asociado a la determinaci\u00f3n de la fuente diet\u00e9tica de los animales migratorios.<\/p>\n\n\n\n
Se dice que las l\u00e1minas de las lentes del globo ocular son ricas en prote\u00ednas. Estas prote\u00ednas est\u00e1n unidas por elementos isot\u00f3picos que dan lugar a una firma isot\u00f3pica que puede evaluarse mediante el an\u00e1lisis de is\u00f3topos estables.<\/p>\n\n\n\n
El pez salm\u00f3n juvenil se estudi\u00f3 en tres h\u00e1bitats isot\u00f3picos diferentes con una red alimentaria distinta para cuantificar el tejido de archivo del globo ocular del pez.<\/p>\n\n\n\n
Los elementos isot\u00f3picos estables utilizados fueron el azufre 35, el carbono 13 y el nitr\u00f3geno 15 (34<\/sup>S, 13<\/sup>C,15<\/sup>N).<\/p>\n\n\n\nEl is\u00f3topo de azufre es \u00fatil para conocer las fuentes de alimentaci\u00f3n. Los peces de la migraci\u00f3n costera son ricos en el is\u00f3topo de carbono 13, por lo que se utiliza para determinar el movimiento migratorio.<\/p>\n\n\n\n
El is\u00f3topo del nitr\u00f3geno se utiliza en el gobierno de los niveles tr\u00f3ficos en los animales migratorios.<\/p>\n\n\n\n
El an\u00e1lisis de is\u00f3topos estables se formula sobre la base del concepto \"somos lo que comemos\".<\/p>\n\n\n\n
Sobre esta base, los cient\u00edficos buscaron elementos isot\u00f3picos como el azufre, el carbono y el nitr\u00f3geno en los tejidos de los peces salm\u00f3n adultos cultivados en tres h\u00e1bitats variantes.<\/p>\n\n\n\n
Su estudio permiti\u00f3 descubrir que los peces criados en la llanura aluvial estacional ten\u00edan m\u00e1s capas del cristalino y crec\u00edan mucho m\u00e1s r\u00e1pido que los criados en el r\u00edo y en el h\u00e1bitat del criadero.<\/p>\n\n\n\n
Asimismo, el an\u00e1lisis isot\u00f3pico revel\u00f3 que los peces ten\u00edan un alto contenido de carbono y azufre debido a los arrozales de la circunvalaci\u00f3n.<\/p>\n\n\n\n
La uni\u00f3n de las prote\u00ednas del globo ocular y el elemento isot\u00f3pico se utiliz\u00f3 para analizar el contenido de la dieta.<\/p>\n\n\n\n
Aparte de esto, los peces salm\u00f3n juveniles ten\u00edan un elemento isot\u00f3pico estable registrado en el cristalino de sus globos oculares, que es lo que llev\u00f3 a la comparaci\u00f3n con los peces adultos para la visi\u00f3n general de su h\u00e1bitat y fuente diet\u00e9tica.<\/p>\n\n\n\n
Esta herramienta de an\u00e1lisis de is\u00f3topos estables (SIA) ha ampliado el alcance de diversos proyectos de conservaci\u00f3n. Podr\u00eda utilizarse para aislar los h\u00e1bitats de diversos animales migratorios, ya que est\u00e1n muy afectados por los cambios clim\u00e1ticos actuales y tambi\u00e9n por las actividades humanas.<\/p>\n\n\n\n
