Ecotones are dynamic over-lapping boundary areas where major
terrestrial biomes meet. As past studies have shown, and as the
chapters in this book will illustrate, their structure, size, and
scope have changed considerably over the millennia, expanding and
shrinking as climate and/or other driving conditions, also changed.
Today, however, many of them are changing at a rate not seen for a
long time, perhaps largely due to climate change and other
human-induced factors. Indeed ecotones are more sensitive to
climate change than the biomes on either side, and thus may serve
as critical early indicators of future climate change. As ecotones
change, they also redefine the limits of the biomes on either side
by altering their distributions of species because, in addition to
their own endemic species, any ecotone will also have species from
both adjoining biomes. Consequently, they may also be places of
high levels of species interaction, serving as active evolutionary
laboratories, which generate new species that then migrate back
into adjacent biomes. Ecotones Between Forest and Grassland
explores how these ecotones have changed in the past, how they are
changing today, and how they are likely to change in the future.
The book includes chapters from around the world with a special
focus on South American and Neotropical ecotones.
The 2021 IPCC report made one thing crystal clear - global climate
change is here to stay. Time is up. We need to act or climate
change will lead to inconceivable suffering by billions of people.
Buying Time for Climate Action is the combined narrative of world
class experts, all committed to help humanity survive its largely
self-induced destructive course. Changing that course requires
urgent action. Determining which actions will lead to helpful
change requires insights into the stumbling blocks that always
emerge when actions aimed at change are planned, resulting in lost
time. The experts who contributed to this volume, through their
expertise, networks, wisdom and creativity, have largely concluded
that the way to cope with the stumbling blocks is to avoid them by
focusing on grassroots initiatives. Their narratives and
discussions, presented in this book, highlight such thinking.The
book is essential reading for anyone committed to help avoid an
existential disaster for humanity, and ready to move plans into
effective action.

Africa is home to an amazing array of animals, including the world's most diverse assortment of large mammals. These include the world's largest terrestrial mammal, the African elephant, which still roams great swathes of the continent alongside a host of hooved mammals such as hippopotamuses, giraffes, rhinoceroses, and zebras.
African Ark: Mammals, Landscape and the Ecology of a Continent tells the story of where these mammals have come from and how they have interacted to create the richly varied landscape that makes up Africa as we know it today. It also highlights small mammals, such as rodents and bats, which are often overlooked by both naturalists and zoologists in favour of their larger cousins.
African Ark explains the processes through which species and population groups are formed and how these fluctuate over time. It explores the impact of megafauna on the environment and the important roles they play in shaping the landscape. In this way, mammals such as elephants and rhinoceros support countless plant communities and the habitats of many smaller animals. The book brings in a human perspective as well as a conservation angle in its assessment of the interaction of African mammals with the people who live alongside them.
African Ark is at once scientifically rigorous - drawing on the contributions of numerous zoologists, ecologists and conservationists - and an engaging read for anyone dedicated to the understanding of Africa and its wildlife.

This is a thoroughly revised and updated edition of an
authoritative introduction to ecological modelling. Sven Erik
Jorgensen, Editor-in-Chief of the journal Ecological Modelling, and
Giuseppe Bendoricchio, Professor of Environmental Modelling at the
University of Padova, Italy, offer compelling insights into the
subject. This volume explains the concepts and processes involved
in ecological modelling, presents the latest developments in the
field and provides readers with the tools to construct their own
models.
The Third Edition features:
A detailed discussion and step-by-step outline of the modelling
procedure.
An account of different model types including overview tables,
examples and illustrations.
A comprehensive presentation of the submodels and unit processes
used in modelling.
In-depth descriptions of the latest modelling techniques.
Structured exercises at the end of each chapter.
Three mathematical appendices and a subject index.
This practical and proven book very effectively combines the
theory, methodology and applications of ecological modelling. The
new edition is an essential, up-to-date guide to a rapidly growing
field.
Presents the most commonly used model types with a step-by-step
outline of the modeling procedure used for eachShows readers
through an illustrated example of how to use each model in research
and management settingsNew edition is revised to include only
essential theory with a focus on applicationsIncludes case studies,
illustrations, and exercises (case study of an ecological problem
with full illustration on how to solve the problem)"
Most of the islands of the Caribbean have long histories of
herpetological exploration and discovery, and even longer histories
of human-mediated environmental degradation. Collectively, they
constitute a major biodiversity hotspot - a region rich in endemic
species that are threatened with extinction. This two-volume series
documents the existing status of herpetofaunas (including sea
turtles) of the Caribbean, and highlights conservation needs and
efforts. Previous contributions to West Indian herpetology have
focused on taxonomy, ecology and evolution, particularly of
lizards. This series provides a unique and timely review of the
status and conservation of all groups of amphibians and reptiles in
the region. This volume introduces the issues particularly
affecting Caribbean herpetofaunas, and gives an overview of
evolutionary and taxonomic patterns influencing their conservation.
Chapters focus on groups that have been relatively neglected in the
Caribbean: amphibians and snakes. A major chapter describes the
problem of invasive species of amphibians and reptiles in the West
Indies. Three chapters then deal with islands of the Wider
Caribbean that share many of the same problems but fall outside the
West Indies biogeographic region: the Atlantic islands of the
Bermuda group; the Dutch continental shelf islands of Aruba,
Curacao and Bonaire, and the Neotropical islands of Trinidad and
Tobago. The book will be useful to biologists and conservationists
working in or visiting the Caribbean, and internationally as a
summary of the current situation in this diverse and important
region.
Biological invasions - the introduction of living organisms beyond
their original range - are one of the main drivers of biodiversity
loss. They are a major threat to human health and a source of pests
and pathogens in the world's farms, forests and fisheries. The
growth of international trade and travel means that more species
are being introduced to more places than ever before. This book
represents the first concerted effort to understand the economic
causes and consequences of biological invasions. The volume
discusses the theoretical and methodological issues raised by
invasion, including control strategies, modelling options, and a
study of the economic, institutional and policy conditions that
predispose countries to biological invasions. Also included are
case studies of fisheries, agricultural systems, tropical forests
and protected areas affected by invasive species in locations such
as the Black Sea, Australia and Africa, and an evaluation of
control programmes. The Economics of Biological Invasions provides
an important first step towards codification of the advice needed
to develop decision rules, tools and protocols for the effective
management of invasive biological species. This volume will be a
fascinating read for researchers, academics and students in
ecology, economics and environmental science with an interest in
the biodiversity problem. The book will also prove to be essential
reading for policymakers responsible for health, agriculture,
forestry, fisheries and the environment in both developed and
developing countries.
