 | What happens when a fig wasp lays its eggs but fails to pollinate the fig? The trees get even by dropping those figs to the ground, killing the baby wasps inside. ...> Full Article |
 | Increasing temperatures at high altitudes are fueling the post-1950 growth spurt seen in bristlecone pines, the world's oldest trees, according to new research. The pines near treeline have wider annual growth rings for the period from 1951 to 2000 than for the previous 3,700 years. Regional temperatures, particularly at high elevations, have increased during the same 50-year time period. The finding is another example of changes in high-elevation ecosystems that are linked to warming temperatures. ...> Full Article |
 | Tree-dwelling ants generally live in harmony with their arboreal hosts. But new research suggests that when they run out of space in their trees of choice, the ants can get destructive to neighboring trees. ...> Full Article |
 | For the first time researchers have run an electrical circuit entirely off power in trees. The findings suggest a new power source for wireless sensors -- and a way to monitor tree health. ...> Full Article |
Large trees have declined in Yosemite National Park during the 20th century, and warmer climate conditions may play a role. The number of large-diameter trees in the park declined 24 percent between the 1930s and 1990s. USGS and University of Washington scientists compared the earliest records of large-diameter trees densities from 1932-1936 to the most recent records from 1988-1999.

Here's one more reason to say 'shade grown, please' when you order your morning cup of coffee. Shade coffee farms, which grow coffee under a canopy of multiple tree species, not only harbor native birds, bats and other beneficial creatures, but also maintain genetic diversity of native tree species and can act as focal points for tropical forest regeneration.

 | A gigantic palm that flowers itself to death has been discovered in Madagascar. This previously unknown genus is entirely new to science and has been named Tahina spectabilis in the latest issue of the Botanical Journal of the Linnean Society, which is Malagasy for "blessed" or "to be protected", and is also one of the given names of Anne-Tahina Metz, the daughter of the discoverer of the palm. ...> Full Article |
