Invasive species: Danger for domestic biodiversity!

Invasive species: Danger for domestic biodiversity!

A current study shows alarming knowledge about invasive animal species: In their original homeland, many of them are seriously threatened with extinction. According to the investigation by the University of Vienna and the University of La Sapienza in Rome, 36 species in their home area are at risk of the 230 non -home mammal species introduced worldwide. These include animals introduced by humans such as the hiking rat, the Mufflon and the Mink, which have become native to new regions, but also disappear in their origin, as krone.at reported.

The nature conservation paradox

This phenomenon, which is known as the "nature conservation paradox", is a significant challenge for nature conservation. Researchers around Franz Essl explain that non -Heilische populations may even be able to contribute to the survival of endangered species in their homeland. However, many of these species in their original habitat, including as a result of rainforest destruction and over hunting, are at risk. This is a result of human activities that lead to these animals being transferred to other areas. In addition, globalization makes it more difficult to protect biodiversity, since not only domestic but also introduced populations should play a role in evaluating the extinction of the extinction href = "https://medienportal.univie.ac.at/aktuelle-pressemayungen/detailsicht/artikel/naturschutz-paradoxon-invasive-art-in-ihrer-Heimat-oft-daht/"> Medien portal of Vienna illustrated.

Research also shows that non -local populations can have negative effects on domestic biodiversity. The example of the Schopfmakaken illustrates this: While its stocks drop drastically on new guinea, this primacy spreads on other islands. The study aims to develop a better understanding of the problem of invasive species and work on how both the endangered species in their home area and the populations introduced can be effectively protected. The challenge for future nature conservation measures will be to correctly evaluate these complex relationships and to find solutions that take into account both domestic and non -local species.
