Why we do what we do\u2026the temperate rainforests of Chile are some of the rarest forests on Earth \u2013 not much remains of these habitats anywhere in the world. Temperate rainforests receive more than 100 inches (254 centimeters) of rainfall each year, qualifying as rainforests \u2013 but they do not exist at tropical latitudes. A swath of the coastal mountain range in Chile and the Andean foothills in Chile and adjacent Argentina were once covered with these forests. Today, only forest fragments exist. These forests have been isolated for a very long time. The Atacama Desert to the north, the Pacific Ocean to the west, and the Andes Mountains to the east have served as barriers such that most of the fauna and flora in this region is endemic (found no place else on Earth). So it\u2019s time to meet the inhabitants of this special place. I\u2019ll start with this species \u2013 the Darwin\u2019s Frogs (Rhinoderma darwinii). These unique amphibians were “discovered” by Charles Darwin on his famous Beagle voyage – folks had known of them prior but this was the first biologist that brought them into focus with regard to western science. Both species of Darwin\u2019s Frogs employ a unique reproductive behavior. Males brood their developing tadpoles inside of their vocal sacs. Female Darwins Frogs deposit eggs on the damp forest floor of the temperate rainforests of Chile and Argentina after approaching a calling male. The males fertilizes the eggs and remain nearby. Just after the eggs hatch, the male takes the tadpoles into his mouth and manipulates them through a hole below his tongue and into his vocal sac. They will remain there and pass all the way through their development into small frogs (in Rhinoderma darwinii). When the babies are ready to live on their own, the male literally \u201ccoughs\u201d up fully developed miniatures of the adults. With Chile\u2019s Darwins Frog (Rhinoderma rufum) males \u201ccough up\u201d late stage tadpoles into pools of water. These frogs are endangered. Chile\u2019s Darwins Frog has not been observed in over 30 years. The Darwins Frog (Rhinoderma darwinii) has suffered a range decline owing to emergent infectious disease and habitat loss. These individuals were photographed in Southern Chile (except for the captive bred baby). This is one of the focal species for the collaboration between San Antonio Zoo, the Roger Williams Park Zoo, and the Austral University in Valdivia, Chile.<\/span><\/p>\n\n\n

Por qu\u00e9 hacemos lo que hacemos … las selvas templadas de Chile son algunos de los bosques m\u00e1s raros de la Tierra, no quedan muchos restos de estos h\u00e1bitats en ning\u00fan lugar del mundo. Las selvas tropicales templadas reciben m\u00e1s de 100 pulgadas (254 cent\u00edmetros) de lluvia cada a\u00f1o, calific\u00e1ndose como selvas tropicales, pero no existen en las latitudes tropicales. Una franja de la cordillera costera en Chile y las estribaciones andinas en Chile y Argentina adyacente alguna vez se cubrieron con estos bosques. Hoy en d\u00eda, solo existen fragmentos de bosque. Estos bosques han estado aislados durante mucho tiempo. El Desierto de Atacama al norte, el Oc\u00e9ano Pac\u00edfico al oeste y la Cordillera de los Andes al este han servido como barreras para que la mayor parte de la fauna y la flora en esta regi\u00f3n sean end\u00e9micas (no se encuentra en ning\u00fan otro lugar en la Tierra). As\u00ed que es hora de conocer a los habitantes de este lugar especial. Comenzar\u00e9 con esta especie: las ranas de Darwin (Rhinoderma darwinii). Charles Darwin “descubri\u00f3” estos anfibios \u00fanicos en su famoso viaje al Beagle: la gente los hab\u00eda conocido antes, pero este fue el primer bi\u00f3logo que los enfoc\u00f3 con respecto a la ciencia occidental. Ambas especies de ranas de Darwin emplean un comportamiento reproductivo \u00fanico. Los machos empollan sus renacuajos en desarrollo dentro de sus sacos vocales. Las ranas darwins hembra depositan sus huevos en el suelo h\u00famedo de las selvas templadas de Chile y Argentina despu\u00e9s de acercarse a un macho llamado. Los machos fertilizan los huevos y permanecen cerca. Justo despu\u00e9s de que los huevos eclosionan, el macho se lleva los renacuajos a la boca y los manipula a trav\u00e9s de un agujero debajo de su lengua y en su saco vocal. Permanecer\u00e1n all\u00ed y pasar\u00e1n todo el camino de su desarrollo en peque\u00f1as ranas (en Rhinoderma darwinii). Cuando los beb\u00e9s est\u00e1n listos para vivir solos, el macho literalmente “tose” miniaturas completamente desarrolladas de los adultos. Con los machos de la rana Darwins (Rhinoderma rufum) de Chile se “tosen” los renacuajos de la etapa final en charcos de agua. Estas ranas est\u00e1n en peligro de extinci\u00f3n. La rana Darwins de Chile no se ha observado en m\u00e1s de 30 a\u00f1os. La rana de Darwins (Rhinoderma darwinii) ha sufrido una disminuci\u00f3n en el rango debido a enfermedades infecciosas emergentes y p\u00e9rdida de h\u00e1bitat. Estas personas fueron fotografiadas en el sur de Chile (a excepci\u00f3n del beb\u00e9 criado en cautividad). Esta es una de las especies principales para la colaboraci\u00f3n entre el Zool\u00f3gico de San Antonio, el Zool\u00f3gico Roger Williams y la Universidad Austral en Valdivia, Chile.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
