Scientists see that sea surface temperature impacts drought and flooding in the Amazon rainforest
Rainfall patterns in the Amazon change when humans alter the land during deforestation and farming, causing some areas to suffer drought while other areas succumb to floods. Now, Rong Fu, an atmospheric scientist at the Georgia Institute of Technology, has found that the ocean surface temperature has as much of an impact on rainfall as land cover changes do.

Seeds suffer in rainforest fragments
In a finding that could have important implications for rainforest preservation, a researcher from the University of California, Davis, reports that seeds that fall to the ground in small fragments of tropical rainforests are three to seven times less likely to sprout than those that fall in larger, continuous forests.

Scientists Discover Smallest Frog
A new frog discovered in Cuba by scientists funded by the National Science Foundation is the smallest in the Northern Hemisphere, and is tied for the world record with the smallest frog in the Southern Hemisphere, says a biologist from Pennsylvania State University in a paper published in the December issue of the journal Copeia (1996-12-18)

Scientists Discover Smallest Frog
A new frog discovered in Cuba is the smallest in the Northern Hemisphere and is tied for the world record with the smallest frog in the Southern Hemisphere, say a team of biologists from Cuba and Penn State. The one-centimeter-long frog also is the smallest tetrapod. (1996-11-25)
