The sudden boost trillions of cicadas dying en masse give to North American forests is apparent from a new study published in Science magazine.

The insects emerge from below ground and swarm over the landscape every 13 or 17 years to briefly sing and mate.

Their decomposing carcasses will increase bacteria, fungi and nitrogen in forest soils, Louie Yang shows.

This may explain why trees grow faster following cicada emergences, the University of California scientist says

BRASILIA - About half of Brazil's original Amazon rainforest has been occupied by man, deforested or used for industry like logging and its destruction is worse than government data shows, a leading environmental group said on Tuesday.

The study using satellite photos shows that land occupation and deforestation covers some 47 percent of the world's largest jungle, an area bigger than the continental United States, the Brazilian non-government organization Imazon said.
