Botanists Gerhard Zotz of the Smithsonian Tropical Research Institute and Stefan Wester of the University of Oldenburg in Germany decided to take a closer look at these high-wire bromeliads. They were interested to find out how the growth and survival rates of these plants on electrical cables compared to the growth and survival of plants of the same species growing in trees--their natural environment.

The Encyclopedia of Life is an unprecedented global effort to document all 1.8 million named species of animals, plants and other forms of life on Earth. For the first time in the history of the planet, scientists, students, and citizens will have multi-media access to all known living species, even those that have just been discovered. The Field Museum of Natural History, Harvard University, Marine Biological Laboratory, Smithsonian Institution, and Biodiversity Heritage Library joined together to initiate the project, bringing together species and software experts from across the world.

Healthy reefs with more corals and fish generate predictably greater levels of noise, according to researchers working in Panama. By analysing recordings of coral reefs from the Las Perlas Archipelago in Pacific Panama ( Central America ), marine biologists working from the Smithsonian Tropical Research Institute have found that some reefs are noisier than others, and these differences in noise provide useful information about the health of the reef.
