Maritime canals dissolve natural barriers to the dispersal of marine organisms, thus providing them with many opportunities for natural dispersal, as well as for shipping-mediated transport. The introduction of alien species proved to be one of the most profound and damaging anthropogenic deeds – involving both ecological and economic costs. However, until recently marine bioinvasions were perceived as isolated mishaps. This book is the first to compare the impacts of the three principal maritime canals – Kiel, Panama, Suez – as invasion corridor for alien biota. The three differ in their geographic locations, hydrological regimes, and in their permeability to alien biota. The technological innovations of the 18th century led to an expansion of the network of navigable inland waterways, followed in the 19th century and the early part of the 20th century by the excavation of two interoceanic canals: the Suez Canal opened a direct route from the Mediterranean Sea to the Indo-Pacific Ocean, and the Panama Canal afforded passage between the Atlantic and the Eastern Pacific.
