Thanks for sharing! 😍🐟

Preventing new introductions of highly invasive species with growing presence in the international pet trade is essential to halt their further spread.

Range expansions of both Asian loaches in Europe could lead to an increased distribution overlap with populations of the native M. fossilis, with projections showing P. dabryanus increasing from a current overlap of 0.1% to 4.1% and M. anguillicaudatus from 0.2% to 32.8%.

Our results indicate that both species could spread globally and become invasive in temperate regions of Europe, North and South America, the south-eastern coast of Australia and Asia.

For this purpose, we used species distribution models to estimate the potential global environmental suitability for both Asian loaches and to identify key variables determining current distributions.

In this study, we evaluated the potential of the large-scale loach (Paramisgurnus dabryanus) and the dojo weatherloach (Misgurnus anguillicaudatus) to establish outside their native range, and address potential impacts on the threatened European weatherfish (Misgurnus fossilis).

The introduction of non-native species is a major driver of biodiversity loss, posing a growing threat to freshwater ecosystems globally. This includes two Asian fish species that have recently been detected outside their native range in Europe, North America and Australia.

Gracias!! Claro, cuando te apetezca!! ;)
