 | El sapillo pintojo occidental (Discoglossus galganoi) en un anfibio presente en la mitad occidental de la Península Ibérica, estando muy emparentado genéticamente con otras especies presentes en Iberia como D. pictus y D. jeanneae, de los cuales es prácticamente indistinguible si no analizamos el ADN en laboratorio, de hecho, hasta hace poco todo el complejo del género Discoglossus en Europa se agrupaba bajo una sólo especie.

 | Fernando Martínez-Freiría, Guillermo Velo-Antón and José C. Brito. Diversity and Distributions. This study exemplifies how the combination of phylogeographic and ecological niche-based models is a powerful tool for inferring evolutionary scenarios and responses of species to Pleistocene climatic oscillations. Vipera seoanei responded accordingly to a cold temperate model and fits a simplified example of ‘R’ type species where interglacial warming periods during the Pleistocene probably caused major range reductions with persistence in a single refuge in north-western Iberia. The single mtDNA lineage observed in this study does not support the differentiation at subspecific level in V. seoanei. Leer más. |
A new species of poison dart frog so teeny it can fit on a fingernail has been discovered in a rain forest in Panama, a new study says. Leer más.
A group of Peruvian and Mexican scientists say they have uncovered at least six new species near South America’s most famous archaeological site: Machu Picchu. The discoveries include a new mammal, a new lizard, and four new frogs. While the scientists are working on formally describing the species, they have released photos and a few tantalizing details about the new discoveries. Leer más.
