Reacción a "A quarter of freshwater wildlife is threatened with extinction"

What would you highlight from the study

"Treating water with an ecological approach that is key to preserving the life of numerous organisms and aquatic ecosystems’. While the role of freshwater in meeting human needs is well known, the availability of which will be increasingly constrained by projected population growth and global warming, its role as a living system that preserves essential ecosystem services by hosting an enormous diversity of life is much less well known. However, as the publication points out, these aquatic ecosystems and the life they support are under enormous threat, more so than terrestrial ecosystems, and a shift in catchment management towards policies that allow water ecosystems to self-sustain, regenerate and conserve the enormous diversity they support is needed".

Which of these species are most important in Spain

"Freshwater fish are undoubtedly the most important species in Spain. Spain is home to a unique ichthyofauna, considered the oldest and most endemic in Europe, with a high number of threatened species included in the International Union for Conservation of Nature (IUCN) Red List. This high degree of threat is due to the geographical isolation of the Pyrenees and the internal processes of basin reorganisation, which have favoured a remarkable diversification of these species over time".

Does the study have any notable limitations?

"Some very important groups, such as freshwater molluscs in the Iberian Peninsula, which harbour great diversity, are missing or poorly represented in the analysis’. The lack of population studies and the consideration of these studies as essential for inclusion in a threat category means that many species appear on the Red Lists as data deficient (DD) when they are probably threatened with extinction. Many regions have insufficient monitoring systems for these species that could be covered by modern and inexpensive techniques such as environmental DNA. Lack of modelling to see the real future impact of global change".
