There are many hypotheses describing the interactions involved in biological invasions, but it is largely unknown whether they are backed up by empirical evidence. This book fills that gap by developing a tool for assessing research hypotheses and applying it to twelve invasion hypotheses, using the hierarchy-of-hypotheses (HoH) approach, and mapping the connections between theory and evidence. In Part 1, an overview chapter of invasion biology is followed by an introduction to the HoH approach and short chapters by science theorists and philosophers who comment on the approach. Part 2 outlines the invasion hypotheses and their interrelationships. These include biotic resistance and island susceptibility hypotheses, disturbance hypothesis, invasional meltdown hypothesis, enemy release hypothesis, evolution of increased competitive ability and shifting defence hypotheses, tens rule, phenotypic plasticity hypothesis, Darwin's naturalization and limiting similarity hypotheses and the propagule pressure hypothesis. Part 3 provides a synthesis and suggests future directions for invasion research.

Abby Pena’s hands are full this year. Between school and helping her grandma wrangle her three younger sisters, there is no time for an after-school job, and certainly no money in the budget to get a car. When Brazos High announces a brand new school-wide contest, everyone thinks it sounds lame. Until they learn the winner of the contest gets a brand new car. Mark Caputo is living a lie. His family owns a popular restaurant in town and their favorite pastime is being rich. Only… they’re not rich. His parents’ constant pressure to look the best and be the best has Mark on edge. This new car could give his parents some much needed financial help. Too bad he’s starting off this school contest in last place. Abby and Mark have their own reasons for wanting the car, and so does the rest of the school. As tensions rise and students scramble to win the contest, Abby finds herself battling for first place with the last person she’d ever expect: the super cute Mark Caputo, her new mortal enemy.

This new volume on Biological Invasions deals with both plants and animals, differing from previous books by extending from the level of individual species to an ecosystem and global level. Topics of highest societal relevance, such as the impact of genetically modified organisms, are interlinked with more conventional ecological aspects, including biodiversity. The combination of these approaches is new and makes compelling reading for researchers and environmentalists.

Feeding on Non-Prey Resources by Natural Enemies Moshe Coll Reports on the consumption of non-prey food sources, particularly plant materials, by predators and parasitoids are common throughout the literature (reviewed recently by Naranjo and Gibson 1996, Coll 1998a, Coll and Guershon, 2002). Predators belonging to a variety of orders and families are known to feed on pollen and nectar, and adult parasitoids acquire nutrients from honeydew and floral and extrafloral nectar. A recent publication by Wäckers et al. (2005) discusses the p- visioning of plant resources to natural enemies from the perspective of the plant, exploring the evolutionary possibility that plants enhance their defenses by recru- ing enemies to food sources. The present volume, in contrast, presents primarily the enemies’ perspective, and as such is the first comprehensive review of the nut- tional importance of non-prey foods for insect predators and parasitoids. Although the ecological significance of feeding on non-prey foods has long been underappreciated, attempts have been made to manipulate nectar and pollen ava- ability in crop fields in order to enhance levels of biological pest control by natural enemies (van Emden, 1965; Hagen, 1986; Coll, 1998a). The importance of n- prey foods for the management of pest populations is also discussed in the book.

In this edited volume, global experts in ecology and evolutionary biology explore how theories in ecology elucidate the processes of invasion, while also examining how specific invasions inform ecological theory. This reciprocal benefit is highlighted in a number of scales of organization: population, community and biogeographic. The text describes example invaders in all major groups of organisms and from a number of regions around the globe.

Despite claims to the contrary, the science of ecology has a long history of building theories. Many ecological theories are mathematical, computational, or statistical, though, and rarely have attempts been made to organize or extrapolate these models into broader theories. The Theory of Ecology brings together some of the most respected and creative theoretical ecologists of this era to advance a comprehensive, conceptual articulation of ecological theories. The contributors cover a wide range of topics, from ecological niche theory to population dynamic theory to island biogeography theory. Collectively, the chapters ably demonstrate how theory in ecology accounts for observations about the natural world and how models provide predictive understandings. It organizes these models into constitutive domains that highlight the strengths and weaknesses of ecological understanding. This book is a milestone in ecological theory and is certain to motivate future empirical and theoretical work in one of the most exciting and active domains of the life sciences.

In The Medea Hypothesis, renowned paleontologist Peter Ward proposes a revolutionary and provocative vision of life's relationship with the Earth's biosphere--one that has frightening implications for our future, yet also offers hope. Using the latest discoveries from the geological record, he argues that life might be its own worst enemy. This stands in stark contrast to James Lovelock's Gaia hypothesis--the idea that life sustains habitable conditions on Earth. In answer to Gaia, which draws on the idea of the "good mother" who nurtures life, Ward invokes Medea, the mythical mother who killed her own children. Could life by its very nature threaten its own existence? According to the Medea hypothesis, it does. Ward demonstrates that all but one of the mass extinctions that have struck Earth were caused by life itself. He looks at our planet's history in a new way, revealing an Earth that is witnessing an alarming decline of diversity and biomass--a decline brought on by life's own "biocidal" tendencies. And the Medea hypothesis applies not just to our planet--its dire prognosis extends to all potential life in the universe. Yet life on Earth doesn't have to be lethal. Ward shows why, but warns that our time is running out. Breathtaking in scope, The Medea Hypothesis is certain to arouse fierce debate and radically transform our worldview. It serves as an urgent challenge to all of us to think in new ways if we hope to save ourselves from ourselves.

An early text from Tiqqun that views cybernetics as a fable of late capitalism, and offers tools for the resistance. The cybernetician's mission is to combat the general entropy that threatens living beings, machines, societies—that is, to create the experimental conditions for a continuous revitalization, to constantly restore the integrity of the whole. —from The Cybernetic Hypothesis This early Tiqqun text has lost none of its pertinence. The Cybernetic Hypothesis presents a genealogy of our “technical” present that doesn't point out the political and ethical dilemmas embedded in it as if they were puzzles to be solved, but rather unmasks an enemy force to be engaged and defeated. Cybernetics in this context is the teknê of threat reduction, which unfortunately has required the reduction of a disturbing humanity to packets of manageable information. Not so easily done. Not smooth. A matter of civil war, in fact. According to the authors, cybernetics is the latest master fable, welcomed at a certain crisis juncture in late capitalism. And now the interesting question is: Has the guest in the house become the master of the house? The “cybernetic hypothesis” is strategic. Readers of this little book are not likely to be naive. They may be already looking, at least in their heads, for a weapon, for a counter-strategy. Tiqqun here imagines an unbearable disturbance to a System that can take only so much: only so much desertion, only so much destituent gesture, only so much guerilla attack, only so much wickedness and joy.
