 | El cambio climático podría estar acelerando el proceso de desaparición del coquí, una diminuta rana autóctona de Puerto Rico que es símbolo de la isla y se caracteriza por un particular sonido, según un estudio de la Universidad de Cornell. «En Puerto Rico ya hemos perdido tres de las diecisiete especies de ranas únicas de la isla de desarrollo directo (que no pasan por la fase de renacuajo) desde los años setenta», explicó a Efe la investigadora puertorriqueña Ana Longo, que integra el equipo multidisciplinar responsable de este estudio. |
One hundred million years ago in what is now Myanmar, a lizard snapped off a dragonfly’s head and tried to dash away. Unfortunately, the reptile didn’t escape with its snack: Both creatures were trapped in sticky tree resin, leaving behind a grisly fossilized scene. The find, reported in the 2010 issue of the journal Palaeodiversity, is the oldest example of a dragonfly preserved in amber, or fossilized tree resin. But what makes the find really interesting is the snapshot of ancient life that looks familiar today, said George Poinar, an entomologist and emeritus professor at Oregon State University. |  |

The most comprehensive assessment of the world’s vertebrates confirms an extinction crisis with one-fifth of species threatened. However, the situation would be worse were it not for current global conservation efforts, according to a study launched Oct. 26, 2010 at the 10th Conference of the Parties to the Convention on Biological Diversity, CBD, in Nagoya, Japan. |  |
