Alien species have been transported and traded by humans for many centuries. However,
with the era of globalization, biological invasions have reached notable magnitudes …

The exponential increase in species introductions during the Anthropocene has brought
about a major loss of biodiversity. Amphibians have suffered large declines, with more than …

Nonnative crayfish have been widely introduced and are a major threat to freshwater
biodiversity and ecosystem functioning. Despite documentation of the ecological effects of …

In a rather provocative article, Parker et al.(1999) claimed that, up to then, little scientific
attention had been placed on developing either theoretical or operational generalizations …

We present the most updated list of non-native freshwater fauna established in Portugal,
including the Azores and Madeira archipelagos. This list includes 67 species at national …

The introduction of exotic species in aquatic habitats is one of the causes for the amphibian
declines observed worldwide. In the 1970s, the red swamp crayfish Procambarus clarkii was …

The introduction of some crustacean species has produced alterations of freshwater
environments and declines of native species worldwide. The red swamp crayfish …

Since the first documented declines of amphibian species, researchers have learned how
nonnative species can depress amphibian populations and lead to local extinctions. Here …

Invasive alien predators can impose strong selection on native prey populations and induce
rapid evolutionary change in the invaded communities. However, studies on evolutionary …

Aim Early assessment of the impact of invasive alien species is crucial to set up timely
management, but often the impact is evident when it is too late for action. We evaluated …
