Farm acreage in Latin America is being overrun by jungles, officials say, sparking debate among scientists about how urgent it is to save primeval rain forests. New secondary forests -- from small acreage to much larger swaths of farmland -- are emerging in Latin America, Asia and other tropical regions worldwide, The New York Times reported Friday. One estimate indicates for every acre of rain forest destroyed each year, more than 50 acres of new forest are growing in the tropics on land...

Annemarie Surlykke from the University of Southern Denmark is fascinated by echolocation. She really wants to know how it works. Surlykke equates the ultrasound cries that bats use for echolocation with the beam of light from a torch: you won't see much with the light from a small bulb but you could see several hundred meters with a powerful beam. Surlykke explains that it's the same with echolocating bats. Some have big powerful calls for perception over a long range, while others are said...

Trees in a hyper-diverse tropical rainforest interact with each other and their environment to create and maintain diversity, researchers report in the Oct. 24 issue of the journal Science. This study was conducted in the Yasuni forest dynamics plot of the Pontificia Universidad Cat³lica del Ecuador, the most diverse tropical forest site associated with the Center for Tropical Forest Science/Smithsonian Institution Global Earth Observatory network (CTFS/SIGEO). It is difficult to...

By Gary Bogue PANAMA CITY, Panama PANAMA CITY is an amazing city. Its skyline is certainly as spectacular as San Francisco's -- some might even say more so -- with its tall skyscrapers. And more modern buildings are under construction, even as we speak. (Donald Trump is building the Trump Ocean Club International Hotel and Tower in the shape of a 68-story sail!) What makes this cosmopolitan city amazing is that it springs up out of a primitive rain forest. A green jungle is just a...

Common tree species in the Amazon will survive even grim scenarios of deforestation and road-building, but rare trees could suffer extinction rates of up to 50 percent, predict Smithsonian scientists and colleagues in the Aug. 12 issue of the journal Proceedings of the National Academy of Science. How resilient will natural systems prove to be as they weather the next several decades of severe, human-induced global change? The debate is on between proponents of models that maximize and...
