Of Beaks and Bites

Stowaway mosquitoes, arriving in the Galapagos Islands aboard aircrafts carrying workers and tourists, have the potential of introducing fatal viruses to the native finch species of the islands, birds made famous by the evolutionary studies of Charles Darwin and others.

Scientists have captured mosquitoes surviving in the holds of arriving planes. Though none of the insects found so far has carried a lethal virus, such as West Nile, they have the potential to do so.

The finches lack natural immunological protection from many viruses, due to their island isolation far from the mainland. Conservationists are recommending that planes leaving mainland Ecuador for the Galapagos be sprayed with insecticide before departure.

'TRUE FACTS'

European environmentalists are blaming intensive farming for the recent death of a horse and the collapse of its rider on a beach in Brittany, France, according to New Scientist magazine. Fertilizer runoff from nearby farms, they say, created a mat of algae on the beach, which releases toxic hydrogen sulfide gas as it rots.

QUIRKS OF NATURE

Australian scientists report that climate change is causing some indigenous bird species to shrink.

They suggest rising temperatures may be degrading some habitats, resulting in poorer avian diets. Warmer weather may also be giving a competitive edge to smaller birds, since they are better able to cool off.

WHERE IN THE WORLD? ANSWER

The Vredefort dome in the Free State of South Africa. This is the largest and oldest of 174 characterized impact structures on Earth, places where large cosmic objects have struck the planet. It is 100 miles in diameter and estimated to be 2 billion years old.

By comparison, the Barringer crater, a tourist attraction 43 miles east of Flagstaff, Ariz., is less than a mile across and estimated to be just 49,000 years old.

The Escher Museum

The Hague, Netherlands
