Write numbers of the texts into the circles in the picture according to the effect which the text
describes.
1 1. A stalagmite is a kind of a
dripstone. It is a karst effect which
grows from the bottom of a cave
where drop water solutions
enriched with dissolved mineral
components.
3 A stalactite is a karst effect which
grows from the ceiling of a cave or
from a skew surface where flow
water solutions enriched with
dissolved mineral compomnents.
2 A stalagnite is a karst pillar.
Stalagnites arises by growing a
stalactite and a stalagmite
together. A stalagnite can also
arise when a stalactite grows to
the bottom or on the contrary a
stalagmite grows to the ceiling
of a cave.

How is a cave created?
Caves are underground cavities created either at the same time with rocks or later by outer
processes. They are created by rocks` dissolving (mailny limestone). Primarily rain water and
carbon dioxide help to the process. Such caves we call karst caves.
If caves are created by weathering (air flowing), we call them pseudo-karst caves. There can flow
small rivers, brooks in caves and sometimes we can find there even lakes.

A unique data bank
In some caves there were preserved bones of hundreds specimen of a cave bear, a cave hyena, a
hairy rhino, a sabretooth tiger and lots of other extinct animals. Other caves contain remains of
human skeletons, products and pieces of work. The most famous are paintings on the walls,
which helped to solve a lot of mysteries in a human history.
We can find there remains of small mammals and shells of molluscs. All these things piled up in
the caves for thousands years and they provide evidence about fauna development in various
periods.

Fauna in caves
1. A life in darkness
Different beetles, grigs, centipedes, multipedes and spiders have often bizzare
shapes and colours of body and limbs. They adapt to the cave`s surrounding, where
is darkness, dampness and the same temperature during the whole year. There live
small mites and colembolans. We can find there also water and land gasteropods.

Animals in a cave are mixed. Match a number of a name to a correct picture.
7. Polydesmida
1. a horseshoe bat
2. An Oxychilus cellarius
6. a colembolan
5. a moth
4. an epeira diadema
3. a long-eared bat
Flora in caves
Botanists won`t be enthused by a visit of a cave. In the permanent darkness there grow only some
mildews, green plants don`t grow there at all.Only on places where is a hole which enables light
penetration we can find small oases of green plants, mainly mosses and ferns.

2. Chiropterans of twilight and their mysteries
Chiropterans orientate themselves and hunt with help of catching anacamptic sound
waves - called echolocation. You will learn more about the effect in an information
box. According to the learnt information fill in the picture which sound is produced
by a bat and which one is a anacamptic sound.
Echolocation
Bats orientate themselves during their night flights with the help an of ultrasound`s reflection
from different obstacles. This way of oreintation we call echolocation (echo= an echo, location =
position finding).
Bats find their prey by producing for us inaudible shouts and they accept reflected signals by
their sensitive hearing. They are able to evaluate the time which passes from the moment of
signal sending and accepting it and fix the distance and obstacles` shape. They are even able to
define the speed and direction of a prey`s movement: a signal reflected from a coming insect. The
range of bats` echolocator is up to one hundred metres.

3. A wing structure
Have a look at the pictures and you will find out that small bones covered with a
membrane are actually prolonged fingers. Write names of particular fingers in the
picture (e.g. a thumb).

and the real bats. They are the only flying mammals.
Have a look at the pictures of horseshoe bats and bats. To each statement write if it
defines a horseshoe bat or a bat.. The statement about a horseshoe bat mark H and
about a bat mark B.

DISCOVERING CHYNOVSKA MYSTERIES
Visit a Chynovska cave and try to find out why is this area important. Then write down which
measures and types of protection are used in the area of a natural sanctuary. A quarry on a Pacova
mountain is a part of a complex where you can find besides other things a precious hepatica.
