Preecha Jiabyu used to take tourists on a rowboat to see the banks of the Mae Klong River aglow1 with thousands of fireflies.
"The firefly populations have dropped 70 percent in the past three years," said Preecha, 58, a former teacher who started providing dozens of rowboats to compete with polluting motorboats.
The fate of the fireflies drew more than 100 entomologists and biologists to Thailand's northern city of Chiang Mai for an international symposium4 on the "Diversity and Conservation of Fireflies."No single factor is blamed, but researchers in the United States and Europe mostly cite urban sprawl5 and industrial pollution that destroy insect habitat. The spread of artificial lights also could be a culprit, disrupting the intricate mating behavior that depends on a male winning over a female with its flashing backside.
Republican presidential candidate John McCain stunned6 the U.S. political establishment and bolstered7 his image as a maverick8 by choosing the little-known female governor of Alaska as his running mate in the race against Democrat9 Barack Obama.
McCain's choice of Sarah Palin also means that no matter who wins in November, U.S. history will be made: Either the first black man will become president or the first woman will be vice10 president.
Palin offers risks and rewards for McCain. The choice of a 44-year-old, first-term governor to be his vice president could undermine one of McCain's main campaign themes: that Obama, a 47-year-old first-term senator, is too inexperienced to become president.
But Palin, whose nomination11 was announced on Aug. 29, could help McCain rally social conservatives, a core Republican constituency that has had an uneasy relationship with McCain. Palin has a strong anti-abortion record and opposes gay marriage.
