Introducing a species into a place where it is not native is never a good idea.\u00a0 More times than not, the introduced species creates serious environmental problems.\u00a0 Often times, the problems are not things that could have easily been predicted.\u00a0 Native species often suffer after introductions.\u00a0 Introduced species may use native species as prey, they might out compete native species, or they may degrade some aspect of the habitat that ultimately hurts native species.<\/p>\n

Introducir una especie en un lugar donde no es nativa nunca es una buena idea.\u00a0 La mayor\u00eda de las veces, las especies introducidas crean graves problemas ambientales.\u00a0 Muchas veces, los problemas no son cosas que podr\u00edan haberse predicho f\u00e1cilmente.\u00a0 Las especies nativas suelen sufrir despu\u00e9s de las introducciones.\u00a0 Las especies introducidas pueden utilizar especies nativas como presas, pueden competir con las especies nativas o pueden degradar alg\u00fan aspecto del h\u00e1bitat que, en \u00faltima instancia, perjudica a las especies nativas.<\/span><\/pre>\n
One introduction that threatens to pose serious problems in Chile is that of the African Clawed Frog (Xenopus laevis).\u00a0 This aquatic species is native to Africa but has been introduced to areas around the world.\u00a0\u00a0\u00a0Because these frogs do so well in aquaria, they\u00a0have been\u00a0used for human pregnancy testing, in genetics, developmental, and environmental toxicology\u00a0labs, and they have been a staple in the pet trade. \u00a0African Clawed Frog are\u00a0voracious predators, eating any small aquatic animal that it can fit into\u00a0their mouth.\u00a0 These frogs can produce potent skin toxins and can poison larger native species that try to eat them.\u00a0 Importantly, African Clawed Frogs carry but are not damaged by the disease, amphibian chytrid fungus.\u00a0 In carrying the disease on their skin, they can spread the disease to native species as they are moved around by humans.\u00a0 African Clawed Frogs are often kept as pets in aquariums.\u00a0 The problem is that when the pet owner changes the water, that water is infected with amphibian chytrid fungus.\u00a0 The water winds up in a local wetland and exposes native amphibians to the disease.\u00a0 Amphibian chytrid fungus has devastated amphibian communities around the globe.\u00a0 Moving African Clawed Frogs around, in the pet trade or otherwise, is risky and could seriously damage native amphibian populations.<\/p>\n
Una introducci\u00f3n que amenaza con plantear serios problemas en Chile es la de la rana de u\u00f1as africana (Xenopus laevis).\u00a0 Esta especie acu\u00e1tica es originaria de \u00c1frica pero se ha introducido en zonas de todo el mundo.\u00a0\u00a0\u00a0Debido a que a estas ranas les va tan bien en los acuarios, se han utilizado para pruebas de embarazo en humanos, en laboratorios de gen\u00e9tica, desarrollo y toxicolog\u00eda ambiental, y han sido un elemento b\u00e1sico en el comercio de mascotas. \u00a0Las ranas de garras africanas son depredadores voraces que comen cualquier peque\u00f1o animal acu\u00e1tico que pueda caber en su boca.\u00a0 Estas ranas pueden producir potentes toxinas para la piel y pueden envenenar a especies nativas m\u00e1s grandes que intenten com\u00e9rselas.\u00a0 Es importante destacar que las ranas africanas con garras son portadoras de la enfermedad del hongo quitridio anfibio, pero no las da\u00f1an.\u00a0 Al portar la enfermedad en la piel, pueden transmitirla a las especies nativas a medida que los humanos los mueven.\u00a0 Las ranas de garras africanas a menudo se mantienen como mascotas en acuarios.\u00a0 El problema es que cuando el due\u00f1o de la mascota cambia el agua, esa agua se infecta con el hongo quitridio anfibio.\u00a0 El agua termina en un humedal local y expone a los anfibios nativos a la enfermedad.\u00a0 El hongo quitridio de los anfibios ha devastado comunidades de anfibios en todo el mundo.\u00a0 Mover ranas de garras africanas, para el comercio de mascotas o de otro modo, es riesgoso y podr\u00eda da\u00f1ar gravemente a las poblaciones de anfibios nativos.<\/span><\/pre>\n
