The use of land for agriculture and building cities everywhere favor the same species.
Animals such as rats and pigeons replace other animals, such as tigers, which can only survive in certain habitats.
The researchers badyzed 20,000 animals. and plants in 81 countries.
And they found that the most common fauna and flora species tend to increase in man-modified locations – forest plantations, farmland, pastures and urban environments.
However, species geographically "We show all over the world that when humans alter habitats, these unique species are systematically lost and replaced by species found everywhere, such as pigeons in cities and rats in agricultural areas, "he said.

One of the authors, researcher Andy Purvis, of "
" As small independent retailers close their doors, the big networks take over, "he said. the same cities, and it's harder to say where you are in. In the same way, people affect nature wherever they go and everywhere local species struggle for survival. "
The results of study are important for wildlife conservation efforts. because species that live only in small areas are already at greater risk of extinction than species that have adapted to life around the world.
Previous research has shown that geographically rare animals and plants also play an important and important role in the ecosystem. and can be vital to our food security.
