The
giant panda
, or
panda
(
Ailuropoda
melanoleuca
, literally meaning
cat-foot
[2]
is a
bear
[3]
native to central-
western and south western
China.
[4]
It is easily
recognized
by its large, distinctive
black patches around the eyes, over the ears, and
across its round body.
Though it
belongs to the order
Carnivora
, the panda's diet
is 99%
bamboo
.
[5]
Pandas in the wild
will
occasionally eat other grasses, wild tubers, or
even meat in the form of birds, rodents or
carrion. In captivity they may receive
honey, eggs, fish, yams,
shrub
leaves
, oranges, or bananas
along with specially prepared
feed.
[6][7]
The giant panda
lives in a few mountain ranges in central
China, mainly in
Sichuan
province, but also
in the
Shaanxi
and
Gansu
provinces.
[8]
Due to
farming,
deforestation
and
other development, the panda has been driven out
of the lowland areas where it
once
panda is a
conservation
reliant
endangered
species
.
[4]
A
2007 report shows 239
pandas living in
captivity inside China and another 27 outside the
country.
[9]
Wild population
estimates vary; one estimate shows that
there are about 1,590 individuals living in the
wild,
[9]
while a
2006 study via
DNA analysis
estimated that this figure could be as high as
2,000 to
3,000.
[10]
Some
reports also show that the number of pandas in the
wild is on the rise.
[11][12]
However, the
IUCN
does not believe there is enough certainty yet to
reclassify the species from
Endangered
to Vulnerable.
[1]
While the
dragon
has historically
served as China's
national
emblem
,
in recent decades
the panda has also served as an emblem for the
country. Its image appears on a
large
number of modern Chinese commemorative silver,
gold, and platinum coins. Though the
panda is often assumed to be docile, it
has been known to attack humans, presumably out of
irritation rather than
predation.
Diet
Despite its
taxonomic
classification as
a
carnivoran
, the
giant panda's
diet
is primarily
herbivorous
, consisting
almost exclusively of
bamboo.
[22]
However,
the giant panda still has the digestive
system of a carnivore, as well as carnivore-
specific genes,
[30]
and thus derives little energy and
little protein from consumption of bamboo. Its
ability to digest
cellulose
is ascribed to the microbes in its
gut.
[31]
The giant panda is
a
with
[25]
The
average
giant panda eats as much as 9
to 14 kg (20 to 30 pounds) of bamboo shoots a day.
Because the
giant panda consumes a diet
low in nutrition, it is important for it to keep
its digestive tract
full.
[22]
The
limited energy input imposed on it by its diet has
affected the panda's behavior. The giant
panda tends to limit its social
interactions and avoids steeply sloping terrain in
order to limit its
energy
expenditures.
[32]
Two of the
panda's most distinctive features, its large size
and its round
face, are
adaptations
to its bamboo
diet. Panda researcher
Russell
Ciochon
observed that:
“[much]
like the vegetarian
gorilla
, the low body
surface area to body volume [of the giant panda]
is
indicative of a lower metabolic
rate. This lower metabolic rate and a more
sedentary lifestyle
allow the giant
panda to subsist on nutrient poor resources such
as bamboo.”
[32]
Similarly,
the
giant panda's round face is the
result of powerful jaw muscles, which attach from
the top of the
head to the
jaw.
[32]
Large molars crush
and grind fibrous plant eat any of
twenty-five bamboo species in the wild,
such as
Fargesia
dracocephala
[33]
and
Fargesia
rufa
.
[34]
Only a few bamboo species are
widespread at the high altitudes pandas now
inhabit. Bamboo
leaves contain the
highest protein levels; stems have
less.
[35]
Given this large
diet, the giant panda
can defecate up
to 40 times a
day.
[36]
Because of the
synchronous flowering, death, and
regeneration of all bamboo within a
species, the giant panda must have at least two
different
species available in its
range to avoid starvation. While primarily
herbivorous, the giant panda still
retains decidedly ursine teeth, and
will eat meat, fish, and eggs when available. In
captivity, zoos
typically maintain the
giant panda's bamboo diet, though some will
provide specially-formulated
biscuits or other dietary
supplements
Golden snub-nosed monkey
The
golden snub-nosed
monkey
(
Rhinopithecus
roxellana
) is an
Old World
monkey
in the
Colobinae
subfamily.
[1]
It is
endemic
to a small area in
temperate, mountainous
forests
of
central
and
Southwest
China
.
[3]
The
Chinese
name
is
sichuan
golden
hair
monkey
(
川金丝猴
).
It
is
also
widely
referred
to
as
the
sichuan
snub-nosed
monkey.
[4][5][6]
Snow
occurs
frequently
within its range
and it can withstand colder average temperatures
than
any
other
non-human
primates.
[7]
Its
diet
varies
markedly
with
the
seasons,
but
it
is
primarily
an
herbivore
with
lichens
being
its
main
food
source.
It is diurnal and
largely arboreal, spending some 97% of their time
in
the canopy. There are three
subspecies. Population estimates range from
8,000 to 15,000 and it is threatened by
habitat
loss
.
[2]
The adult
and
subadult golden snub-nosed monkey
is
sexually dimorphic
. Adult
males
(estimated at over 7 years of
age) have large bodies covered with very
long,
golden
guard
hairs
on
their
backs
and
cape
area.
The
crest
is
medium
brown
while
the
back,
crown
to
nape
,
arms
and
outer
thighs
are
deep
brown.
Subadult
males
(estimated
at
5
–
7
years
of
age)
are
more
slender
than
adult
males.
The
golden
guard
hairs
are
short
and
sparse,
and
their
crests
show
females (estimated at over 5 years of
age) are about
half the size of adult
males. The golden guard hairs are also present on
the
back
and
cape
area,
but
they
are
shorter
in
length
than
in
the
males.
The brown crest shows
microbanding
. Their breasts
and nipples are
lt females are about
two-thirds the size of adult females.
The body hair is brown, gradually
turning golden but without the golden
guard hairs. The crest shows
microbanding. The breasts and nipples are
not as large as in adult les (at least
1 year of age) are
quite small, being
less than two-thirds the size of adult females.
The
body
hair
is
light
brown,
turning
reddish
gold
with
time.
The
rest
of
their
body hair is brown.
Sexual discrimination is difficult because their
external genital organs are
underdeveloped. Infants (age 3 months to a
year)
are
light
brownish
gray
or
light
brown,
appearing
white
in
sunlight.
Their
sex
cannot
be
identified
at
this
age.
