List
of Life
Academy
scientists are compiling a list of all the birds and mammals in
a threatened corner of China.
The
holiday season often inspires people to start making a list (and
checking it twice), but this year two Academy scientists are working
on a list of a different kind - an inventory of all of the birds
and mammals that live in China's Gaoligong Mountains. Rising from
the western edge of Yunnan Province, the steep slopes of the Gaoligong
Mountains have become a last refuge for a large number of endangered
species in China, including clouded leopards and Bengal tigers.
However, hunting and logging loom as threats to the area's rich
wildlife. To document this biodiversity before it disappears, Academy
scientists Douglas Long and Maureen Flannery recently met up with
a team of Chinese colleagues from the Kunming Institute of Zoology
and spent five weeks conducting a survey of the birds and mammals
that inhabit the Gaoligong range.
While
in the field, the mammalogists documented 25 different species of
poorly known small mammals, including three types of bats that likely
represent new records for southwest China. They also trapped an
intriguing insectivore called a gymnure, which is distantly related
to hedgehogs. Scientists have yet to determine the gymnure's place
on the evolutionary tree, so the team took tissue samples that can
be used to conduct DNA analysis. Meanwhile, the ornithologists captured
and studied over 75 species of birds. They documented altitude and
habitat information for each species - data that can be used to
inform future conservation decisions.
