Both of these species have spread around the world, which is a disaster

Biodiversity – biological invasions of certain species of amphibians and reptiles, a source of destruction Environmental conditions They colonize, are plentiful and subject to astronomical costs. According to a study conducted Scientific report, spent 17 billion in just thirty years to combat invasive amphibians and reptiles. Two species stand out very clearly from the lot.

The bullfrog, also called the bullfrog, and the brown tree snake are responsible for these costly eradication efforts. The frog Only 96.3% of the $6.3 billion committed to the fight against invasive amphibians. The brown snake represents 99.7 percent of the 10.4 billion attempts against reptiles.

Both of these species have many aspects that are highly detrimental to biodiversity and agricultural activities. The frog reproduces very quickly and sometimes eats species that are essential to the ecosystem. The the serpent, meanwhile, can destroy a farm in its path. Thanks to the European Union bullfrog eradication plan in 2016, France also experienced a drastic decline in the number of these stowaways.

From Invasion to Extinction

Europe and Australia top the list of countries that have spent more than $10 billion to see them disappear. But whatever their location, the reason these rude guests are established is none other than human: as the authors suggest, the worldwide traffic of exotic species is responsible for this.

Transportation of species It is an unprecedented intensification into new territories and is accelerating with the globalization of trade and transport networks. These phenomena often lead to invasions, which involve environmental impacts Species extinction Indigenous populations and disturbances in the functioning of local ecosystems.

Therefore, the researchers suggest that the costs associated with amphibian and reptile invasions can be reduced by investing in measures aimed at limiting the global movement of invasive species and by early detection of invasions.
