Loss of big fruit-eating birds impacting trees in endangered rainforests
The extinction of large, fruit-eating birds in fragments of Brazil’s Atlantic rainforest has caused palm trees to produce smaller seeds over the past century, impacting forest ecology, finds a study published in the journal Science. The researchers — led by Mauro Galetti from Brazil’s Universidade Estadual Paulista — looked at Euterpe edulis palm seeds in […]
An insidious threat to tropical forests: over-hunting endangers tree species in Asia and Africa
A fruit falls to the floor in a rainforest. It waits. And waits. Inside the fruit is a seed, and like most seeds in tropical forests, this one needs an animal—a good-sized animal—to move it to a new place where it can germinate and grow. But it may be waiting in vain. Hunting and poaching […]

Sprinkled with pollen, buzzing bees fly from one blossom to another, collecting sweet nectar from brilliantly colored flowers. Bees tend to symbolize the pollination process, but there are many wild insects that carry out the same function. Unfortunately, wild insect populations are in decline, and, according to a recent study, adding more honey bees may […]
