The Garden of Eden as the ideal and untouched site of life's
creation persists in popular thought, even as we have uncovered a
lengthy fossil record and developed a scientific understanding of
evolution. The continent of Africa is a good candidate for Eden:
its generally warm climate, rich vegetation, and variety of animal
species lend themselves easily to such a comparison. Yet in the
time since the first primates appeared millions of years ago,
Africa has undergone profound alterations in physical geography,
climate, and biota.
Linking the evidence of the past with that of the present, this
exquisitely illustrated guide examines the evolution of the
mammalian fauna of Africa within the context of dramatic changes
over the course of more than 30 million years of primate presence.
The book covers such topics as dating, continental drift, and
global climate change and the likely motors of evolution as well as
the physical evolution of the African continent, including present
and past climates, and the major determinants of plant and mammal
distributions. The authors discuss human evolution as a part of the
larger pattern of mammalian evolution while responding to the
unique interest that we have in our own past.
The meticulous reconstructions of fossil mammals in this book
are the result of detailed anatomical research. Restorations of
mammalian musculature and appearance take into account the
affinities between fossil forms and extant species in order to make
well-founded inferences about unpreserved animal attributes.
Environmental reconstructions benefit from the authors' visits to
more than a dozen wildlife preserves in five African countries as
well as the use of an extensive database of published studies on
the evolution of landscapes on the continent. A fascinating read
and a visual feast, "Evolving Eden" lays the foundation for a
deeper appreciation of contemporary African wildlife.
Bats are fascinating mammals about which we still have much to
learn. As well as using ultrasonic echolocation calls for
orientation and while foraging, they also have a complex array of
vocalisations for communication. These are known as social calls
and are an essential component of their colonial lifestyle. This
book brings together the current state of knowledge of social calls
relating to the bat species occurring within Britain and Ireland,
with some additional examples from species represented elsewhere in
Europe. It includes access to a downloadable library of calls to be
used in conjunction with the book. Downloadable call library Social
calls are complex and intriguing to listen to; they are after all
produced with listeners in mind (other bats). To enjoy and fully
appreciate social calls the reader must also have the opportunity
to become a listener: each of the presented sonograms in the book
is cross-referenced to downloadable 'time expanded' .wav sound
files which are contained within a much wider library of calls for
you to explore. Included in Social Calls of the Bats of Britain and
Ireland The authors start with an overview of the species of bats
in Britain and Ireland (Chapter 1), and then introduce us to
communication within the social world of bats (Chapter 2).
Referencing the latest research, the authors explore how these
calls can be classified according to their structure, and in many
cases the context in which the calls are thought to be emitted
(Chapter 3). Chapter 4 addresses aspects of survey methodology to
be considered by those studying social calls. This leads on to the
analysis of calls (Chapter 5), detailing the specific methods used
and parameters commonly measured by researchers. The final, and
main chapter (Chapter 6) introduces the 23 species covered in the
book giving each a detailed profile including: habitat preferences,
typical roosting locations, roost emergence times, mating
strategies and maternity behaviour. Each species profile includes
what is known about the social calls for that species and this text
is supported by colour sonograms (created using Pettersson BatSound
V4.1) of most of the calls discussed. Each sonogram is linked to a
.wav sound file (Time Expansion x10) within the downloadable
library. The sound files allow the reader to hear, as well as see,
the calls produced using any bat sound analysis software that
supports the .wav format. The authors conclude with a bibliography
and an extensive list of references directly cross-referenced
throughout the book.
