A new report published in the journal Global Change Biology shows that 45 species of the Galapagos Islands have become extinct or are facing extinction largely due to human activities.

The main causes are the 1982 El Nino and overfishing. The results show the great vulnerability of this diverse area to significant climate change and human activities.

New Zealand Custom officials at the Christchurch International Airport got quite the surprise Sunday evening.  A 58-year-old man from Germany was attempting to board a flight when he was searched by Customs officials. 

A new species of monitor lizard closely related to the Komodo dragon has been discovered by German scientists in Indonesia.

The discovery was made after close examination of the new specimen using morphological characteristics and DNA analysis. Taxonomically classified as Varanus lirungensis, the new species “illustrates the high diversity of monitor lizards in Indonesia,” according to André Koch, who found the lizard.

The Galapagos form of the black salt marsh mosquito has changed its diet to prefer reptile blood instead of feeding on mammals and birds. This discovery has some scientists fearing the introduction of a new mosquito-borne disease which could devastate the Galapagos native wildlife.

In the Western Ghats mountain range of India researchers discovered a dozen frog species.

Sathyabhama Das Biju, from the University of Delhi and Franky Bossuyt from the Free University of Brussels discovered the tree frogs at night while hiking in mountain forests during the monsoon season. (The same researchers were responsible for the discovery of the ‘purple frog’ in 2003 in the same area.) All of the frogs are in the Philautus genus, which has no tadpole stage during maturation.

Henry the Tuatara, has suddenly regained his sexual vigor, and scientists in a New Zealand zoo are excited that he is becoming a dad, after nearly 40 boring years living a life of an eunuch. Science world is also excited with Henry’s newly acquired fame, largely because his family is ‘ancient’, even pre-dating evolution of the dinosaurs.

A large part of the excitement, however, is not that Henry seems to be racing against time but he is enjoying the company of three mates in his sunset years. He has lived long, though, with his species having a lifespan of about 70 years in the wild.
