for plants and animals much of
Australia is a difficult place for most of the
year little rain falls and the moisture the
does reach the ground evaporates quite quickly -living things tend to dry out temperature variations
to r extreme on a hot summer afternoon the ground surface may be over 70
degrees Celsius at a winter dawn the temperature maybe below freezing. The soil in many places is dry and Sandy it plans managed to
survive here and other animals to once I love animal
life is occasional holes in Santa ground each
about four centimeters in diameter such holes are often found amongst the
porcupine grass plants have Central and Western Australia plan sometimes called spinifex usually business I know what is responsible for
the holes unless you go looking after doc this little animal with its large eyes
long years from tale with a tough to appear on the
end and long hind legs is a desert hopping
mouse biologists know it has not only is Alexis the spinifex hopping
mouse hoping my so usually about and active at night porcupine grass like many other plans so
the dry in land produces an abundance of seed this is an
important item in the hopping mouse tired hoping my school so eat other vegetable
matter and any small insects they find as they move about they continually made
other mice usually the smell is a familiar one for helping my sis live together with
others in the group ok perhaps 10 to 15 or so all have a familiar odor sometimes though a hopping mouse with an
unfamiliar smelled comes into a feeding area usually the strange a retreat from the
area from time to time the mice go back down
their holes and into their underground burrows a hopping last photo can be in large and
complex affair with underground tunnels larger chambers and vertical shafts leading to popo’s at the ground surface
to make their Baron hoping mice dig their first up on
Downers untangle until they are well below the surface
then the horizontal tunnels the Chamber’s and the popos the original opening is filled in inside the Baram hoping mice continually
made other mice from there own colony part of the time spend grooming
themselves but for much of each day the my sleep
huddled together in one of the chambers deep inside the
Barrow occasionally this significant rain in the area
followed by a flash revenue growth this can lead to a new patent activity in the hopping mouse colony several
weeks after the rain young animals make their appearance two
or three small naked young are born to each female each is blinded first like the young other mammals young
hopping mice are cared for by the adults the mother provides a supply of milk the young develop fairly quickly at
seventeen days or so there eyes still closed but they can feed and
groom themselves by 21 days there Iza open by other 28 days they can look after themselves and by about fifty days they to a
capable of breeding provided that the food supply is
sufficient if the food supply remains good over a
long period as a topping mice may keep reading and
become very numerous many new colonies begun the fact that hopping mice can
live at all in inland Australia and become very
abundant at times suggest that this somehow will suited to
the dry conditions and temperature extremes found them nights in winter can be cold and the day’s cold too but by living
much of the time underground helping my stay warmer than that the
surface it may be 0 above-ground and fifteen degrees in the nest chamber
by huddling together to individual hopping mice lose less
heat and stay warmer the hottest weather is met on summer days with the stand at
the surface at sixty or seventy degrees and too hot to walk on the temperature a meter under the soil
is really about 32 degrees Celsius there the mice remain until surface conditions a cooler in hot
with the two the my soul is an active as a result they produce less heat they also stop
huddling and spread themselves out in this way they lose more heat and even if their
body temperature rises they can tolerate a greater temperature
rise than most other mammals the way they behave then helps them to survive temperature
extremes they also have ways of coping with the
water shortage we’re hoping my slew there’s little water to drink they gain
much of their water from the food they eat and seem to be very good retaining this
water in their bodies living in a bottom and coming out only at night for
instance hopes to save water with conditions more humid then they lose less water by the operation
also adult animals take in the urine produced
by the yen as a result the water that makes up much
of the year and has saved and the adults themselves produce very
little urine so the behavior updates at helping my eyes and the ways
in which their bodies function seem to help these little animals to
survive the water shortage and extreme temperatures have been land
Australia their body structure to seems to help their survival not many animals for example have long
back legs like there’s a popping mice those legs are a structural feature that
seems to help them survive in particular circumstances like other organisms hopping mice have predators which feed
on them one is the bomb now mice on the ground I continually on the alert watch what
happens when dangerous detected rapid movements with many changes of
direction the my so hard to catch now watch them
in slow motion look particularly at the way they use their back legs the long back legs up hopping mice them
are a structural feature that affects the way they move and seems to help them avoid attacks by
predators like towels study of the lives of desert helping my
eyes suggests that the way their bodies a build the
ways in which they function and the ways in which the animals behave all suit them very well to the life they
lead in the sandy desert country inland Australia helping my sis well adapted to their environment and
way of life p up
