Martin Stevens explores the extraordinary variety of senses in the
animal kingdom, and discusses the cutting-edge science that is
shedding light on these secret worlds. Our senses of vision, smell,
taste, hearing, and touch are essential for us to respond to
threats, communicate and interact with the world around us. This is
true for all animals - their sensory systems are key to survival,
and without them animals would be completely helpless. However, the
sensory systems of other animals work very differently from ours.
For example, many animals from spiders to birds can detect and
respond to ultraviolet light, to which we are blind. Other animals,
including many insects, rodents, and bats can hear high-frequency
ultrasonic sounds well beyond our own hearing range. Many other
species have sensory systems that we lack completely, such as the
magnetic sense of birds, turtles, and other animals, or the
electric sense of many fish. These differences in sensory ability
have a major bearing on the ways that animals behave and live in
different environments, and also affect their evolution and
ecology. In this book, Martin Stevens explores the remarkable
sensory systems that exist in nature, and what they are used for.
Discussing how different animal senses work, he also considers how
they evolve, how they are shaped by the environment in which an
animal lives, and the pioneering science that has uncovered how
animals use their senses. Throughout, he celebrates the remarkable
diversity of life, and shows how the study of sensory systems has
shed light on some of the most important issues in animal
behaviour, physiology, and evolution. He also describes evidence of
the disruptive effects of human activities on the way other animals
navigate the world.

Martin Stevens examines the four extant complete cycles of
Middle English mystery plays in light of the most recent research
on the manuscripts, sources, and records relating to the medieval
drama. The first comprehensive treatment of all four of the cycles,
the book emphasizes the study of the surviving manuscripts as texts
distinct from their performance history.

The Princeton Legacy Library uses the latest print-on-demand
technology to again make available previously out-of-print books
from the distinguished backlist of Princeton University Press.
These paperback editions preserve the original texts of these
important books while presenting them in durable paperback
editions. The goal of the Princeton Legacy Library is to vastly
increase access to the rich scholarly heritage found in the

2012 is the new Y2K. Instead of sitting back laughing and pointing
at everyone that is in a panic over the end of the world, scheduled
for December 21, 2012, why not profit from it instead? This book
will give you many legitimate ideas for making money over the 2012
scare, as well as a few humorous ones. Bottom line, if the world
ends in 2012, well, you may actually save some lives. If it doesn't
end, maybe you'll be wealthy because you took action
Beauty is more than skin deep. 'The natural world is awash with
colour, but we are only seeing half the story. If we could see
things as animals do, our world would become unimaginably brighter.
Now, thanks to new science and technology, we can at last open our
eyes.' - Sir David Attenborough In nature, colour is more than a
source of beauty; it's a form of vital communication. Depending on
the situation, colour says different things - it can be an
expression of power or seduction, warning or deceit - and it can
even, occasionally, save your life. Accompanying a major new BBC
series with David Attenborough, Life in Colour explores the
fascinating story of how colour works in the natural world. From
the 'trichromatic' vision of Silver Leaf Langurs, which allows them
to see orange and red against forest foliage - the colours not only
of ripe fruit, but of their young - to African Mandrills who use
their colouration to do battle, Professor Martin Stevens reveals a
complex system of messaging visible only to those who know the
code. Based on the latest scientific research in the field, and
illustrated with stunning photography throughout, Life in Colour
reveals a world previously unknown to us.
Dieser Ratgeber ist ein hilfreicher Begleiter fur alle, die eine

In nature, trickery and deception are widespread. Animals and
plants mimic other objects or species in the environment for
protection, trick other species into rearing their young, lure prey
to their death, and deceive potential mates for reproduction.
Cuckoos lay eggs carefully matched to their host's own clutch.
Harmless butterflies mimic the wing patterning of a poisonous
butterfly to avoid being eaten. The deep-sea angler fish hangs a
glowing, fleshy lure in front of its mouth to draw the attention of
potential prey, while some male fish alter their appearance to look
like females in order to sneak past rivals in mating. Some orchids
develop the smell of female insects in order to attract
pollinators, while carnivorous plants lure insects to their death
with colourful displays. In this book, Martin Stevens describes the
remarkable range of such adaptations in nature, and considers how
they have evolved, and become increasingly perfected as part of an
arms race between predator and prey or host and parasite. He
explores the work of naturalists and biologists from Alfred Russel
Wallace to current research, showing how scientists find ways of
testing the impact of particular behaviours and colourings on the
animals it is meant to fool, as opposed to our human perceptions.
Drawing on a wide range of examples, Stevens considers what
deception tells us about the process of evolution and adaptation.
In the last decade, research on the previously dormant field of
camouflage has advanced rapidly, with numerous studies challenging
traditional concepts, investigating previously untested theories
and incorporating a greater appreciation of the visual and
cognitive systems of the observer. Using studies of both real
animals and artificial systems, this book synthesises the current
state of play in camouflage research and understanding. It
introduces the different types of camouflage and how they work,
including background matching, disruptive coloration and
obliterative shading. It also demonstrates the methodologies used
to study them and discusses how camouflage relates to other
subjects, particularly with regard to what it can tell us about
visual perception. The mixture of primary research and reviews
shows students and researchers where the field currently stands and
where exciting and important problems remain to be solved,
illustrating how the study of camouflage is likely to progress in
the future.
