Amphibians are the extant descendants of the first vertebrate class
to successfully colonize terrestrial environments; hence they
occupy a unique position between fish and reptiles. Amphibian skin
provides essentially no resistance to evaporative water loss, and
consequently daily water turnover rates are an order of magnitude
greater than in other terrestrial vertebrate groups. This has led
to a suite of physiological, morphological and behavioural
adaptations that have allowed a successful terrestrial existence in
spite of this apparently spendthrift water retention
strategy.
Ecological and Environmental Physiology of Amphibians provides a
synthesis of current research on the comparative physiology of
amphibians with a particular emphasis on water balance. It adopts a
strong environmental perspective and includes a wealth of
information on ecology, phylogeny and development. As with other
books in the Ecological and Environmental Physiology Series, the
emphasis in this book is on the unique physiological
characteristics of the amphibians, although the latest experimental
techniques and future research directions are also considered. This
accessible text is suitable for both graduate students and
researchers in the fields of amphibian comparative physiology and
physiological ecology, including specialist courses in amphibian
ecology. It will also be of value and use to the many professional
herpetologists requiring a concise overview of the topic.
This book describes one of our closest relatives, the orangutan,
and the only extant great ape in Asia. It is increasingly clear
that orangutan populations show extensive variation in behavioral
ecology, morphology, life history, and genes. Indeed, on the
strength of the latest genetic and morphological evidence, it has
been proposed that orangutans actually constitute two species which
diverged more than a million years ago - one on the island of
Sumatra the other on Borneo, with the latter comprising three
subspecies.
This book has two main aims. The first is to carefully compare data
from every orangutan research site, examining the differences and
similarities between orangutan species, subspecies and populations.
The second is to develop a theoretical framework in which these
differences and similarities can be explained. To achieve these
goals the editors have assembled the world's leading orangutan
experts to rigorously synthesize and compare the data, quantify the
similarities or differences, and seek to explain them.
Orangutans is the first synthesis of orangutan biology to adopt
this novel, comparative approach. It analyses and compares the
latest data, developing a theoretical framework to explain
morphological, life history, and behavioral variation.
Intriguingly, not all behavioral differences can be attributed to
ecological variation between and within the two islands; relative
rates of social learning also appear to have been influential. The
book also emphasizes the crucial impact of human settlement on
orangutans and looks ahead to the future prospects for the survival
of critically endangered natural populations.
How does a mudskipper fish manage to “walk” on land? Why is the
Hoatzin also known as ‘The Stinkbird’? And once the female Pipa
toad has laid her eggs, where does she put them? The answers? The
mudskipper can “walk” using its pectoral fins, the Hoatzin has
a unique digestive system which gives the bird a manure-like odour,
and the female Pipa Toad embeds its eggs on its back where they
develop to adult stage. Illustrated throughout with outstanding
colour photographs, Strange Animals presents the most unusual
aspects of 100 of the most unusual species. The selection spans a
broad spectrum of wildlife, from the tallest land living mammal,
the giraffe, to the light, laughing chorus of Australian kookaburra
birds, from the intelligence of the Bottlenose dolphin to octopuses
that change colour when they dream to the slow pace of the
three-toed sloth. Arranged geographically, the photographs are
accompanied by fascinating captions, which explain the quirky
characteristics of each entry. Including egg-laying mammals, birds,
reptiles, amphibians, cannibalistic insects and other
invertebrates, Strange Animals is a compelling introduction to some
of nature’s most curious beasts.
Until about 13,000 years ago, Europe and North America were home to
a menagerie of massive mammals. Mammoths, camels, and lions walked
the ground that has become our cities and streets. Then, just as
the first humans reached the Americas, these Ice Age giants
vanished forever. In Once and Future Giants, science writer Sharon
Levy digs through the evidence surrounding Pleistocene large animal
("megafauna") extinction events worldwide, showing that
understanding this history-and our part in it-is crucial for
protecting the elephants, polar bears, and other great creatures at
risk today. These surviving relatives of the Ice Age beasts now
face an intensified replay of that great die-off, as our species
usurps the planet's last wild places while driving a warming trend
more extreme than any in mammalian history. Inspired by a passion
for the lost Pleistocene giants, some scientists advocate bringing
wolves back to Scotland, and elephants to America's Great Plains as
stand-ins for their extinct native brethren. By reintroducing big
browsers and carnivores to colder climes, they argue, we could
rescue some of the planet's most endangered animals while restoring
healthy prairie ecosystems. Critics, including biologists enmeshed
in the struggle to restore native species see the proposal as a
dangerous distraction from more realistic and legitimate
conservation efforts. Deftly navigating competing theories and
emerging evidence, Once and Future Giants examines the extent of
human influence on megafauna extinctions past and present, and
explores innovative conservation efforts around the globe. The key
to modern-day conservation, Levy suggests, may lie fossilized right
under our feet.
The karst landforms of China are renowned around the world for the
beauty of their landscapes, but it is less well appreciated that
they also contain extensive cave systems with very significant
underwater habitats. China also has an extremely high level of
biodiversity, including over 1,500 freshwater fish species.
Unsurprisingly, some of these species inhabit the karst cave
systems and have flourished and diversified under unique
environmental conditions. As a result, cave fishes in China are
particularly abundant and diverse when compared to those of other
countries of the world. These remarkable fishes have received
considerable research attention from Chinese ichthyologists and,
for the first time, this book makes their resulting findings
directly accessible to the English-speaking world through a
remarkable endeavour of Sino-British collaboration.
A book of evocative and atmospheric photographs taken by Dick
Hawkes to create a representative record of this precious and
ecologically unique habitat - before much of it is lost to the many
threats it faces. Chalk streams have been described as England's
"rainforest". Around 85% of the world's chalk streams are in
England. They are beautiful, biologically distinct and amazingly
rich in wildlife, but are under threat from man-made issues of
abstraction, pollution from chemicals and effluent, development for
housing, and climate change. Included in the book are images of
typical habitats and species of wildlife found in chalk streams and
water meadows, highlighting those that are rare or most under
threat.
Sentient assembles a menagerie of zoological creatures – from land,
air, sea and all four corners of the globe – to understand what it
means to be human. Through their eyes, ears, skins, tongues and noses,
the furred, finned and feathered reveal how we sense and make sense of
the world, as well as the untold scientific revolution stirring in the
field of human perception.
The harlequin mantis shrimp can throw a punch that can fracture
aquarium walls but, more importantly, it has the ability to see a vast
range of colours. The ears of the great grey owl have such unparalleled
range and sensitivity that they can hear twenty decibels lower than the
human ear. The star-nosed mole barely fills a human hand, seldom
ventures above ground and poses little threat unless you are an
earthworm, but its miraculous nose allows it to catch those worms at
astonishing speed – as little as one hundred and twenty milliseconds.
Here, too, we meet the four-eyed spookfish and its dark vision; the
vampire bat and its remarkable powers of touch; the bloodhound and its
hundreds of millions of scent receptors, as well as the bar-tailed
godwit, the common octopus, giant peacocks, cheetahs and golden
orb-weaving spiders. Each of these extraordinary creatures illustrates
the sensory powers that lie dormant within us.
In this captivating book, Jackie Higgins explores this evolutionary
heritage and, in doing so, enables us to subconsciously engage with the
world in ways we never knew possible.
Discover the astonishing truth about our aquatic cousins: how they
think and what they know, their experiences and unique behaviours,
and the many things we have in common. There are 33,000 species of
fish on our planet, and that number is constantly increasing. In
context, that is more than all the species of mammals, birds,
amphibians and reptiles added together, making fish the most
numerous vertebrates on our planet. Waters worldwide are teeming
with these elusive creatures, but how much do we really know about
them? Grouped into thematic chapters - including the Dangerous and
Deadly,Unusual Giants and Mini Marvels - in this comprehensive book
biologist Doug Mackay-Hope profiles the secret lives of 50 of our
most interesting underwater cousins in an insightful and
myth-busting study, complete with charming watercolour diagrams and
expert insights. Learn about the White-Spotted Pufferfish, whose
spines hide a deadly toxin, or the Ocellate River Stingray, who
lurks in the rivers of South America and who can kill with just one
touch of it's barbed stinger. Meet Bargibant's Pygmy Seahorse, who
measures just 2cm in length, as well as the enourmous Whale Shark,
which grows to around 13m in length. Be fascinated by the wierd
creatures of the deep ocean, such as the Peter's Elephantnosed Fish
or the kaleidescopic Picasso's Triggerfish. With a foreword by
Jeremy Wade, presenter of River Monsters and Mighty Rivers, and
official fish aficionado, this book is a complete compendium of
fascinating fish facts, with maps showing where in the globe they
can be found, plus facts on how they live, hunt and escape
predators. Beautiful illustrations and photographs accompany each
entry, as well as interesting facts on how they evolved to adapt
tochanging environments, making this book the perfect guide to all
things aquatic.
