    Shrews, Introduced Fish, and High-Mountain Lakes: A Fragile Ecological Balance

    A new study reveals that the introduction of fish into high-mountain lakes significantly disrupts biodiversity in these ecosystems, directly impacting shrews. Lakes containing fish show a notable decline in aquatic invertebrate populations, an essential food source for these small insectivorous mammals. Furthermore, large fish can prey on the shrews themselves, threatening their survival and altering…
