Extinct may not be forever for some species of Galapagos tortoises
Yale scientists report that genetic traces of extinct species of Galapagos tortoises exist in descendants now living in the wild, a finding that could spur breeding programs to restore the species, The report appears in Proceedings of the National Academy of Sciences. view more (2008-09-23)
The tourist trap
Mosquitoes with the potential to carry diseases lethal to many unique species of Galapagos wildlife are being regularly introduced to the islands via aircraft, according to new research published today. view more (2009-08-12)
Community participation online
A slow-moving tortoise could never be beaten in a race, greek philosopher Zeno of Elea claimed. The pursuer would first have to reach the point at which the tortoise had set off. Since that point is constantly moving, the creature stays in the lead, admittedly at a decreasing distance but which never reaches zero. This paradox problem was once the... view more... (2002-12-20)

ESA's Medspiration project branches out to support biodiversity
Maps of the sea surface temperature around Galapagos Islands and Cocos Island in the Pacific Ocean are being produced daily and are available online in full resolution in near-real time as part of the Medspiration project, an ESA-funded effort to represent the most reliable temperature of the seas on a global basis. view more (2007-03-20)
Hotspots or Not? Isotopes Score One for Traditional Theory
One great beauty of plate tectonics theory is that it explains so many geological phenomena at one time. But plate tectonics could not explain the location of many volcanic islands - Hawaii, the Azores or the Galapagos Islands, often called "hotspots" - far from the edge of tectonic plates. view more (2006-12-07)
Study investigates 'divorce' among Galapagos seabirds
Being a devoted husband and father is not enough to keep an avian marriage together for the Nazca booby, a long-lived seabird found in the Galapagos Islands off the coast of Ecuador. view more (2007-06-13)
Ecological significance of tool-use in the woodpecker finch Cactospiza pallida
The Woodpecker finch, one of 14 Darwin`s finches of the Galapagos Islands, uses twigs or cactus spines to pry insects and spiders out of tree-holes. The advantage of using tools may seem evident, but empirical evidence is scarce. In a paper soon to appear in Ecology Letters, Tebbich and colleagues present the first study on the ecological... view more... (2002-09-09)
Animal sacrifice in Brazilian folk religion
Candomblé, a religion practiced primarily in South America and inspired by older African beliefs, makes much use of animal sacrifice. Researchers writing in BioMed Central's open access Journal of Ethnobiology and Ethnomedicine carried out interviews with priests, priestesses and adherents of the religion, documenting the role sacrifice... view more...

El Ni'ħo is yawning
Four years ago, torrential rains battered the Southern US, mudslides struck in Peru - and the inhabitants of Canada`s west coast saved up to 30% on their winter heating bills. The cause? El Ni'ħo, a huge temperature shift in the Pacific Ocean which spawns climate changes globally. Today, using satellite Earth observation data, scientists are... view more... (2002-02-27)
Darwin in a test tube
As described in an article published this week in an advance, online edition of the journal Proceedings of the National Academy of Sciences (PNAS), the work demonstrates some of the classic principles of evolution. view more (2009-04-30)
Stray penguins probably reached northern waters by fishing boat
Guy Demmert got quite a surprise when he hauled a fishing net into his boat off the coast of southeast Alaska in July 2002. There among the salmon, in living black and white, was a Humboldt penguin, thousands of miles from where any of its kind should have been. view more (2007-06-06)
Cornell conservationists propose allowing wild animals to roam parts of North America
If Cornell University researchers and their colleagues have their way, cheetahs, lions, elephants, camels and other large wild animals may soon roam parts of North America. view more (2005-08-18)
ESA launches new project to protect biodiversity
The world's biodiversity is vanishing at an unprecedented rate - around 100 species every day - due to factors such as land use change and pollution. view more (2007-01-10)
Earth's most prominent rainfall feature creeping northward
The rain band near the equator that determines the supply of freshwater to nearly a billion people throughout the tropics and subtropics has been creeping north for more than 300 years. view more (2009-07-02)
Unexpected finding: Some dinosaurs grew slower in hard times
Palaeontologists from the University of Bonn report on an intriguing diagnosis in the 16 December issue of the journal Science. A dinosaur which they have examined was apparently able to vary the speed of its growth according the conditions obtaining in its environment. view more (2005-12-16)
Female iguanas pay high costs to choose a mate
Picking a mate isn't easy-if you are a female iguana. In a study published in the June 27th issue of the online, open-access journal PLoS ONE, Maren Vitousek of Princeton University and colleagues found that female Galapagos marine iguanas spend a lot of energy picking a mate from a wide range of suitors - energy they could otherwise spend... view more...

Penguins setting off sirens over health of world's oceans
Like the proverbial canary in the coal mine, penguins are sounding the alarm for potentially catastrophic changes in the world's oceans, and the culprit isn't only climate change, says a University of Washington conservation biologist. view more (2008-07-01)
Darwin continues to make history
177 years after he made his now famous voyage to the Galapagos Islands and 120 after his death, Charles Darwin is still making history. The University of Cambridge has won a Queen`s Anniversary Prize for Higher and Further Education for the Darwin Correspondence Project, which is transcribing, editing and publishing more than 14,500 letters... view more...

Mice roar message: genetic change happens fast
While looks can be deceiving, heredity is revealing, and two scientists who've studied the genetic makeup of a common field mouse report that what's most revealing to them is how fast both genes and morphology can change. view more (2007-10-22)
