En condiciones normales, la mayor\u00eda de los sapos usan pistas visuales para encontrar, cazar o atrapar su presa.<\/span><\/p>\n

……<\/span><\/p>\n

…..<\/span><\/p>\n

Sin embargo, los sapos ciegos en la isla de Fernando de Noronha han adoptado una estrategia distinta y relajada para alimentarse, seg\u00fan se\u00f1ala un estudio publicado en la revista Journal of Zoology<\/em>.<\/span><\/p>\n

,,,,,,,,<\/span><\/p>\n

,,,,,,<\/span><\/p>\n

\u00abA diferencia de los sapos normales, los que son ciegos literalmente esperan que los insectos caminen sobre ellos antes de com\u00e9rselos<\/strong>\u00ab, dice Luis Felipe Toledo, un bi\u00f3logo especializado en anfibios de la Universidad Estatal de Campinas en S\u00e3o Paulo.<\/span><\/p>\n

,,,,,,<\/span><\/p>\n

,,,,,,<\/span><\/p>\n

Debido a que los sapos ciegos simplemente comen lo que les pasa al lado, ya no est\u00e1n seleccionando sus presas, agrega. \u00abEso causa distintas condiciones en el organismo\u00bb.<\/span><\/p>\n

,,,,,,,,<\/span><\/p>\n

,,,,,,<\/span><\/p>\n

Toledo encontr\u00f3, por ejemplo, que los sapos ciegos ten\u00edan un peso menor que los sapos normales y produc\u00edan menos huevos<\/span><\/p>\n

……<\/span><\/p>\n

..<\/span><\/p>\n

\u00a0<\/span><\/p>\n

As\u00ed que perder la visi\u00f3n ha provocado una serie de efectos en la salud de los sapos, desde cambios en sus t\u00e1cticas depredadoras hasta afectar su estado f\u00edsico.<\/span><\/p>\n

…..<\/span><\/p>\n

…….<\/span><\/p>\n

A pesar de estas deformidades, los curur\u00fa contin\u00faan proliferando en la isla<\/strong>. Una raz\u00f3n es que se trata de una especie introducida y no tiene depredadores naturales o competidores locales.<\/span><\/p>\n

……<\/span><\/p>\n

.<\/span><\/p>\n

Por otra parte, aunque las hembras deformes producen menos huevos, el n\u00famero que expulsa cada una sigue siendo de miles. \u00abEso es suficiente para mantener el impulso poblacional\u00bb, se\u00f1ala Toledo.<\/span><\/p>\n

…<\/span><\/p>\n

….<\/span><\/p>\n

Los renacuajos tambi\u00e9n sufren de varias deformidades<\/strong>. En un estudio de 2014, el equipo de Toledo encontr\u00f3 que casi el 53% de los que inspeccionaron presentaba por lo menos una anomal\u00eda.<\/span><\/p>\n

…<\/span><\/p>\n

…….<\/span><\/p>\n

Esos renacuajos malformados podr\u00edan despu\u00e9s convertirse en sapos deformes o normales.<\/span><\/p>\n

……..<\/span><\/p>\n

Misteriosa llegada<\/strong><\/span><\/p>\n

….<\/strong><\/span><\/p>\n

…<\/strong><\/span><\/p>\n

Nadie sabe <\/strong>con certeza cu\u00e1ndo llegaron los sapos all\u00ed<\/strong>.<\/span><\/p>\n

.<\/span><\/p>\n

..<\/span><\/p>\n

\u00abSeg\u00fan una historia, hace cerca de 100 a\u00f1os un sacerdote se llev\u00f3 algunos sapos de la parte continental de Brasil a la isla para mantener bajo control a los insectos<\/strong> en sus cultivos\u00bb, dice Toledo.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

….<\/span><\/p>\n

Under normal conditions, the majority of toads used Visual cues to find, hunt or trap their prey.<\/span><\/p>\n

…….<\/span><\/p>\n

…..<\/span><\/p>\n

However, on the island of Fernando de Noronha blind toads have adopted a strategy different and relaxed to feed themselves, according to a study published in the journal of Zoology.<\/span><\/p>\n

………<\/span><\/p>\n

…<\/span><\/p>\n

\u00abUnlike normal toads, which are literally blind wait for insects to walk on them before eating them,\u00bb says Luis Felipe Toledo, a biologist specializing in amphibians of the State University of Campinas in Sao Paulo.<\/span><\/p>\n

…….<\/span><\/p>\n

…..<\/span><\/p>\n

Since the blind toads simply eat what happens next, they are no longer selecting prey, adds. \u00abThat causes different conditions on the body\u00bb.<\/span><\/p>\n

———<\/span><\/p>\n

Toledo found, for example, that blind toads had one weight lower than normal toads and produced fewer eggs<\/span><\/p>\n

…..<\/span><\/p>\n

So losing vision has led to a number of effects on the health of frogs, from changes in their predatory tactics to affect their fitness.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

Despite these deformities, the cururu continue to proliferate on the island. One reason is that it is an introduced species and has no natural predators or competitors premises.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

On the other hand, although deformed females produce fewer eggs, the number that each remains of thousands. \u00abThat is enough to maintain the population momentum,\u00bb said Toledo.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

Tadpoles also suffer from various deformities. In a study by 2014, the Toledo team found that nearly 53% of those inspected had at least one abnormality.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

These malformed tadpoles could then become normal or deformed frogs.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

Mysterious arrival<\/span><\/p>\n

\u00a0<\/span><\/p>\n

No one knows for sure when they got there toads.<\/span><\/p>\n

\u00a0<\/span><\/p>\n

\u00abAccording to one story, about 100 years ago a priest took some toads of the continental part of Brazil to the island to keep under control insects in crops\u00bb, said Toledo.<\/span><\/p>\n
