New topics – influence of a man to nature

A man lived as a part of nature in the

past Since he became a breeder instead of a hunter a cultivator instead of a gatherer

he influences nature the most of all live

organisms

Influence of a man to nature

Many species of animals and plants live in closeness to a man – they use the environment changed by a man for their lives.

We call them synanthrop species.

Synathrop species – invasive species

With development of overseas discoveries (America 1492) such species that has never appeared in those places get to the natural biotops.

They do not have natural enemies and become invasive species.

Invasive species

Danger

They push our local species

Suuport soil erosionCan be dangerous to our

health

Invasive species

Reynoutria japonica

Reynoutria japonica

Comes from Japan, China or Korea First in Europe in 1825. In 1848 brought to French court as a

decorative plant. Since then it has spread across Europe

and pushed out former species by the streams and rivers

Invasive species - animals Crayfish - Orconectes limosus

Crayfish - Orconectes limosus

Got to Europe at the end of the 19th century

Dangerous non-native type of crayfish

Resistable more than European crayfish

Able to survive in waters poorer in oxygen and in more acid waters

Crayfish - Astacus astacus

Crayfish - Austropotamobius terrentium

Summary

Homework:

Find out and write main characteristics of at least two plants and two animals that belong among invasive species
