Of the twenty or so science fiction films produced in America during the 1950s, there is a fascinating subset of nine films that do more than portray an invasion. These films use the invasions as metaphors for assaults against the integrity of various things, such as the self, marriage, and notions involving the supremacy of the human race.

Legal and illegal aliens. Ways in which Mexicans try to take possession of the United States under the leadership of left-wing organizations. My book is divided in three parts. The first part consists of a synthesized history of the countries of the immigrants that are concerning to the United States, their governments, their laws and their ways of life. The second part consists of what we can expect from the immigrants according to their habits of life in their home countries, the intentions and actions of the Mexican immigrants and government. The third part or the epilogue consists of the reactions of certain political figures and the U.S. government, and my premonitions.

There are few more active frontiers in plant science than helping understand and predict the ecological consequences of on-going, global changes in climate, land use and cover, nutrient cycling, and acidity. This collection of research papers and reviews focuses on how these changes are likely to interact with two important factors, clonal growth in plants and the introduction of species into new regions by humans, to reshape the ecology of our world. Clonal growth is vegetative reproduction in which offspring remain attached to the parent at least until establishment. Clonal growth is associated with the invasiveness of introduced species, their tendency to spread after introduction and negatively affect other species. Will changes in climate, land cover, or nutrients further increase biological invasions by introduced, clonal plants? The articles in this book seek to address this question with new research and theory on clonal growth and its interactions with invasiveness and other components of global change.

The papers in this book are based on efforts by an international group of soil ecologists to assess the biological and ecological mechanisms of earthworm invasions. They examine their geographic extent and impacts on terrestrial ecosystems, and possible means by which earthworm invasions might be mitigated. The book broadens the discussion on invasion biology and ecology to belowground systems.

Biological invasion of native plant communities is a high-priority problem in the field of environmental management. Resource managers, biologists, and all those involved in plant communities must consider ecological interactions when assessing both the effects of plant invasion and the long-term effects of management. Sections of the book cover human perceptions of invading plants, assessment of ecological interactions, direct management, and regulation and advocacy. It also includes an appendix with descriptive data for many of the worst weeds.

Despite major international investment in biofuels, the invasive risks associated with these crops are still unknown. A cohesive state-of-the-art review of the invasive potential of bioenergy crops, this book covers the identified risks of invasion, distributions of key crops and policy and management issues. Including a section on developing predictive models, this book also assesses the potential societal impact of bioenergy crops and how to mitigate invasive risks.

The diversity of the earth's climates superimposed upon a complex configuration of physical features has provided the conditions for the evolution of a remarkable array of living things which are linked together into complex ecosystems. The kinds of organisms comprising the ecosystems of the world, and the nature of their interactions, have constantly changed through time due to coevolutionary interactions along with the effects of a continually changing physical environ ment. In recent evolutionary time there has been a dramatic and ever-accelerating rate of change in the configuration of these ecosystems because of the increasing influence of human beings. These changes range from subtle modifications caused by anthropogenically induced alterations in atmospheric properties to the total destruction of ecosystems. Many of these modifications have provided the fuel, food, and fiber which have allowed the expansion of human populations. Unfortunately, there have been many unanticipated changes which accompanied these modifications which have had effects detrimental to human welfare in cluding substantial changes in water and air quality. For example, the use of high-sulfur coal to produce energy in parts of North America is altering the properties of freshwater lakes and forests because of acidification.

This book proposes a new, innovative approach that will give you, or your spouse, the ability to prevent, deflect or defeat even the most determined attack against your home. It will suggest a number of measures you can take. It will discuss concepts you won't read anywhere else to provide dramatically better physical security. Most importantly, everything it proposes is cumulative, each step adding to the one previous, so whatever you do will be an improvement over whatever you've done, or not done, in the past.

This book is the first comprehensive global review of all aspects of alien plant invasions in protected areas. It provides insights into advances in invasion ecology emanating from work in protected areas, and the link to locally relevant management support for protected areas. The book provides in-depth case studies, illuminating interesting and insightful knowledge that can be shared across the global protected area network. The book includes the collective understanding of 80 ecologists and managers to extract as much information as possible that will support the long-term management of protected areas, and the biodiversity and associated ecosystem services they maintain. “This outstanding volume draws together pretty much all that can be said on this topic, ranging from the science, through policy, to practical action”. Dr. Simon N. Stuart, IUCN Species Survival Commission, UK. "This important and timely volume addresses two of the most serious problems affecting biodiversity conservation today: assessing the extent to which protected areas are impacted by biological invasions and the complex problems of managing these impacts. Written by leading specialists, it provides a comprehensive overview of the issues and gives detailed examples drawn from protected areas across the world". Professor Vernon H. Heywood, School of Biological Sciences, University of Reading, UK
