The trembling aspen tree takes its name from the fact that the slightest breeze causes the long flat stems attached to the leaves to tinkle.
Rumble in the jungle
Rumble in the jungle Logging activities being carried on in the north
of Sumatra, Indonesia, are threatening a unique population of
tool-using orang-utans. Researchers say that the logging could kill
the population by destroying their habitat and could, in any event,
endanger their unique social behaviour and tool use. Orang-utans
are found only in Borneo and Sumatra, Indonesia, and they are among
the closest relatives to human beings. The Sumatras orang-utans
have developed tools for eating honey, insects and seeds. They dip
twigs, which they have made into probes, into trees to catch
insects and obtain hard-to-reach honey. They also use the twigs to
dig seeds out of fruit that is covered with stinging
hairs. 3 JULY 1999, P. 24
