This pioneering encyclopedia illuminates a topic at the forefront of global ecology—biological invasions, or organisms that come to live in the wrong place. Written by leading scientists from around the world, Encyclopedia of Biological Invasions addresses all aspects of this subject at a global level—including invasions by animals, plants, fungi, and bacteria—in succinct, alphabetically arranged articles. Scientifically uncompromising, yet clearly written and free of jargon, the volume encompasses fields of study including biology, demography, geography, ecology, evolution, sociology, and natural history. Featuring many cross-references, suggestions for further reading, illustrations, an appendix of the world’s worst 100 invasive species, a glossary, and more, this is an essential reference for anyone who needs up-to-date information on this important topic.

Encyclopedia of Biological Invasions features articles on:

• Well-known invasive species such the zebra mussel, chestnut blight, cheatgrass, gypsy moth, Nile perch, giant African snail, and Norway rat

• Regions with especially large numbers of introduced species including the Great Lakes, Mediterranean Sea, Hawaiian Islands, Australia, and New Zealand.

• Conservation, ecological, economic, and human and animal health impacts of invasions around the world

• The processes and pathways involved in invasion

• Management of introduced species



















flea bites, usually from the Oriental rat flea Xenopsylla cheops. Three pandemics of bubonic plague—in the sixth to eighth centuries AD, during medieval times, and from the late nineteenth into the early twentieth century—are estimated to have killed more than 200 million persons. The worldwide pattern of outbreaks in ports during the last pandemic suggests that the disease was probably introduced from infected Norway rats that disembarked from sailing ships or freight vessels accompanied by X.

true seed, as an endocarp containing multiple seeds, and as a dry fruit such as an achene or a caryopsis. All of these are generally lumped as “seed dispersal” because functionally it is the dispersal of the seed that is the focus, even if it is being dispersed within a dry fruit. Some plants also can be dispersed as vegetative propagules, such as torn off stolons of Carex or bulbils of Allium, but the primary focus of this article will be on “seed” dispersal defined broadly. Dispersal syndromes

have been able to recolonize some lower-elevation forests. Much of the ability to adapt will depend on extant genetic variation, population size, gene flow, and mutation rates. Conservation strategies that preserve genetic variation in native populations by conserving large populations and promoting gene flow in increasingly fragmented landscapes may provide genetic variation on which selection can act to ameliorate negative impacts of invaders.

may not have occurred before, done to balance the loss of a similar community or population elsewhere (such as from development). REMEDIATION Similar to mitigation, but with fewer legalistic overtones of one-for-one replacement. This can include the use of biodiversity, such as vegetation buffers, to increase ecosystem function or environmental quality (as in bioremediation). GOALS The list above comprises some of the diversity in the nature and goals of ecological restoration. Still, the most
