German ichthyofauna in the age of the »Homogenocene«:
how invasive fishes benefit from the elimination of geographic barriers and climate change: Recent decades have seen a marked change in the composition of ecological communities in aquatic ecosystems, whereby introduced species increasingly displace indigenous fishes.
In most cases, these changes can be ascribed to human activities: global trade, especially along artificial waterways, has connected previously separated biogeographic regions, allowing certain species to expand their original distribution ranges.
Native and invasive species will likely change their current distribution ranges further as a consequence of the prognosticated climate change. Invasive species often show broad tolerances to altered environmental conditions, promoting their further spread and leading to an increased importance in aquatic ecosystems.
