This book focuses on rarity, its spatial and temporal dynamics,
causes, and interaction with conservation. Although they can be
viewed from many different perspectives, rare species are of
particular concern to conservationists because they tend to have a
greater probability of extinction. This book therefore identifies a
number of important issues both heuristic and practical.
This is the urban century in which, for the first time, the
majority of people live in towns and cities. Understanding how
people influence, and are influenced by, the 'green' component of
these environments is therefore of enormous significance. Providing
an overview of the essentials of urban ecology, the book begins by
covering the vital background concepts of the urbanisation process
and the effect that it can have on ecosystem functions and
services. Later sections are devoted to examining how species
respond to urbanisation, the many facets of human-ecology
interactions, and the issues surrounding urban planning and the
provision of urban green spaces. Drawing on examples from urban
settlements around the world, it highlights the progress to date in
this burgeoning field, as well as the challenges that lie ahead.

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?
No species occurs everywhere. Indeed, the majority are absent from
most places, and where they do occur they are usually quite rare.
Gaston discusses the structure of these distributions - the
structure of the geographic ranges of species.
Gaston is particularly concerned with the factors that determine
the limits to a species' geographic range, how the sizes of those
ranges vary, and patterns in that variation. Also considered are
the distribution of individuals amongst those sites where a species
does occur and what determines that distribution, and some of the
practical implications of all these.
Both in a pure and applied context, ecologists need a broader
perspective on their subject matter than has historically
prevailed. This book provides one such perspective.
A must have book for any researchers and graduate students studying
macroecology, biogeography and conservation biology.
