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

Biological invaders represent one of the primary threats to the
maintenance of global biodiversity, human health, and the success
of human economic enterprises. The continuing globalization of our
society ensures that the need to understand the process of
biological invasion will only increase in the future. There is also
a growing recognition that the study of biological invaders
provides a unique insight into basic questions in ecology and
evolution.
The study of exotic birds has had a particularly long history and
has come to represent a fascinating intersection between the study
of biological invasions, avian conservation biology, and basic
principles of ecology and evolution. Avian Invasions summarizes and
synthesizes this unique historical record and unravels the insights
that the study of exotic birds brings to all three of these
research strands. It includes chapters on the well-known
contributions of exotic bird study to ecological science, and on
the post-establishment evolution of introduced bird populations.
The result is the most comprehensive picture yet of the invasion
process.
Avian Invasions is aimed at professional avian biologists and
ornithologists as well as graduate students of avian ecology,
evolution and conservation. It also appeals to a more general
audience of invasion ecologists.
Macroecology: Concepts and Consequences brings together for the
first time major researchers in the field to present overviews of
current thinking about the form and determinants of macroecological
patterns. Each section presents different viewpoints on the answer
to a key question in macroecology, such as why are most species
rare, why are most species small-bodied, and why are most species
restricted in their distribution?
