Proceedings of a seminar of the National Committee for Biology held on 1st and 2nd April, 2003.
Ecosystems as diverse in location and scale as the Mediterranean, hedgerows, Galapagos, bridges, the Antarctic, roadside verges and Bermuda are considered by the contributors to this volume to illustrate the profound impact that the transport of peoples has had on the environment.
The fragmentation of habitats, pollution, the introduction of alien species and the spread of disease, are among the topics discussed by expert contributors from Ireland, the United Kingdom, Israel and Bermuda.
