Much has been written about dolphins and whales, and excellent
books exist especially on the charismatic bottlenose dolphins; and
killer, humpback, and sperm whales. But detailed studies have been
carried out on a handful of other species, and this book summarizes
our state of knowledge of a little dolphin the southern hemisphere
dusky, and compares its behavioral strategies in different
environs. The editors, Bernd and Mel Wursig, began studying duskies
in Patagonia Argentina in 1972. Although they have been to many
parts of the Earth since then -- including work on Amazon and
Yangtze river dolphins, Hawai i for the delicate lovely spinner
dolphin, the Arctic for bowhead and gray whale work, and bottlenose
dolphins in several milieus -- they have always returned to their
first love of unraveling the social patterns and life strategies of
duskies that exist in small groups in semi-enclosed bays and as
herds of well over one thousand in the open ocean. This book
documents the latest research, from their feeding patterns to their
acrobatic skills. It is full of scientific facts, with a sense of
poetry and wonder of the unknown.
Baring-Gould's eye-opening history of lycanthropy - the werewolf curse - delves deep into the lore, unearthing various historical cases, several of which date back to Ancient or Medieval times. The concept of a human transforming into a wolf has ancient origins, with several Greek and Roman authors such as Virgil, Ovid, Herodotus and Pliny raising the concept in their poetry and other writings. Rumors of sorcery that could induce a human to change was attributed to magicians in far off places such as Scythia, and such beliefs were widely held. Later, the Norse civilization's mythology introduced lycanthropy and other kinds of transformation. Humans as wolves, bears, birds and other beasts were said to appear in the northern wilds; the Norse God Odin took the form of a bird on regular occasions. Berserker warriors would clad themselves in wolf skins; Bj rn, son of Ulfheoin, was famed for his ability to shift between human and wolf forms.
Shortlisted for the James Cropper Wainwright Prize 2022 for Nature Writing - Highly Commended Winner for the Richard Jefferies Award 2021 for Best Nature Writing 'A rural, working-class writer in an all too rarefied field, Chester's work is unusual for depicting the countryside as it is lived on the economic margins.' The Guardian 'An important portrait of connection to the land beyond ownership or possession.' Raynor Winn 'It's ever so good. Political, passionate and personal.' Robert Macfarlane 'Evocative and inspiring...environmental protest, family, motherhood and...nature.' Claire Fuller, author of Unsettled Ground, Costa Novel Award Winner 2021 Nature is everything. It is the place I come from and the place I got to. It is family. Wherever I am, it is home and away, an escape, a bolt hole, a reason, a place to fight for, a consolation, and a way home. As a child growing up in rural England, Guardian Country Diarist Nicola Chester was inexorably drawn to the natural landscape surrounding her. Walking, listening and breathing in the nature around her, she followed the call of the cuckoo, the song of the nightingale and watched as red kites, fieldfares and skylarks soared through the endless skies over the chalk hills of the North Wessex Downs: the ancient land of Greenham Common which she called home. Nicola bears witness to, and fights against, the stark political and environmental changes imposed on the land she loves, whilst raising her family to appreciate nature and to feel like they belong - core parts of who Nicola is. From protesting the loss of ancient trees to the rewilding of Greenham Common, to the gibbet on Gallows Down and living in the shadow of Highclere Castle (made famous in Downton Abbey), On Gallows Down shows how one woman made sense of her world - and found her place in it.
The study of fish neuroendocrinology has had a significant impact
on our general understanding of the functional roles and evolution
of a variety of neurochemical messengers and systems. Not only do
fish possess unique neuroendocrine features, they have also been
and remain an important vertebrate models for the discovery of new
neuropeptides. In the last fifty years, neuroendocrinologists have
documented a complex and seemingly infinite number of interactions
between hormones and nerve structures. Gradually emerging from this
knowledge is an understanding of the specific neurohormonal
pathways and the messengers responsible for maintaining homeostasis
in an aquatic environment and for regulating the functional systems
that allow for the highly diverse life histories and reproductive
tactics of fish
* Comprehensive and an easily accessible reference volume for developing, running, and analyzing biomedical research using the rat as model system Grown exponentially by the genomic revolution, the use of the rat as a model of choice for physiological studies continues in popularity and at a much greater depth of understanding.

As a volume in the highly successful Methods in Molecular BiologyT series, this work provides the kind of detailed description and implementation advice that is crucial for getting optimal results. Comprehensive and up-to-date, Rat Genomics: Methods and Protocols thoroughly covers the current techniques used in labs around the world and overviews the applications of the data obtained, making it certain to be useful to the scientific community as a key source of references and methods.
Periods of environmental hypoxia (Low Oxygen Availability) are
extremely common in aquatic systems due to both natural causes such
as diurnal oscillations in algal respiration, seasonal flooding,
stratification, under ice cover in lakes, and isolation of densely
vegetated water bodies, as well as more recent anthropogenic causes
(e.g. eutrophication). In view of this, it is perhaps not
surprising that among all vertebrates, fish boast the largest
number of hypoxia tolerant species; hypoxia has clearly played an
important role in shaping the evolution of many unique adaptive
strategies. These unique adaptive strategies either allow fish to
maintain function at low oxygen levels, thus extending hypoxia
tolerance limits, or permit them to defend against the metabolic
consequences of oxygen levels that fall below a threshold where
metabolic functions cannot be maintained.
Cilia--the tiny hairlike structures on the surface of cells--have recently been identified as playing a role in a variety of disease and developmental disorders. Absent or defective cilia in certain cells can cause infertility, blindness, kidney disease, and lung disease. This volume presents recent findings in cilia research and current thought on the role of cilia in disease and developmental abnormalities.
Written with the non-specialist in mind, this guide is a must-have for flower lovers, hikers, tour guides and tourists – anyone interested in identifying the wild flowers that grace the Cape Peninsula. Wild Flowers of the Cape Peninsula covers the most remarkable and commonly seen wild flowers of Table Mountain, Silvermine and Cape Point. The book was originally published as Common Wild Flowers of Table Mountain in 2007, then revised in 2013 to include the flowers of Silvermine. This new edition offers:
This second volume in the series covers such topics as DNA fingerprinting of fishes, the cytochromes P450 in fish, the molecular biology of bacterial fish diseases, and new insights into the origins of the diversity and distribution of fish antifreeze proteins. The book will be of great value to fisheries scientists, animal biochemists, physiologists and endocrinologists, and aquaculturists. It will provide researchers and students alike with a pertinent information source from theoretical and experimental angles.
This is the companion volume to Daniel Klionsky s "Autophagy: Lower
Eukaryotes, " which features the basic methods in autophagy
covering yeasts and alternative fungi (aspergillus, podospora,
magnaporthe). Klionsky is one of the leading authorities in the
field. He is the editor-in-chief of "Autophagy." The November 2007
issue of "Nature Reviews" highlighted his article, Autophagy: From
phenomenology to molecular understanding in less than a decade. He
is currently editing guidelines for the field, with 230
contributing authors, that will publish in "Autophagy."
Elwyn Simons has held professional appointments at Yale University (1960-1977), Duke University (1977-present), and was the Director of the Duke Primate Center (1977-1991) and Scientific Director (1991-2001). He has authored nearly 300 scientific publications and is the holder of many high honors. He is a member of the United States National Academy of Sciences, the American Philosophical Society, as well as many other professional associations. He was elected a Knight of the National Order by the government of Madagascar and has been the recipient of many awards including the prestigious Charles R. Darwin Award for Lifetime Achievement from the American Association of Physical Anthropologists. For nearly a half century, Dr. Simons has dominated the study of primate evolution. The volume summarizes the current state of knowledge in many aspects of primate and human evolution that have been studied by Simons and his colleagues and place it in a broader paleontological and historical perspective. Elwyn Simons: A Search for Origins contains the results of new research and reviews of many of the critical issues in primate and human evolution during the last half of the twentieth century as well as aspects of African paleontology and primate conservation in Madagascar. The authors are an extremely distinguished group of international authorities on all aspects of primate and human evolution and primate behavior. Although linked primarily by their connection to Simons? own career, the chapters include a wide range of important new works that are valuable contributions to the field of physical anthropology and paleontology and are certain to be widely cited and used in teaching.Several of the papers (Simons et al., Wing et al., Seiffert et al., Gingerich, O?Conner) are broad reviews of the history of research and discoveries in the fossil deposits of the Fayum, Egypt that have formed the background of our understanding of anthropoid evolution for over a century and will be important researchers for students and researchers in primate evolution and African paleontology. Similarly, broad reviews of the history of primate paleontology and human evolution (Rasmussen, Pilbeam, Wood; Sussman and Hart) will be essential reading in courses in primate and human evolution as well as the history of physical anthropology. Other authors describe new research results on early anthropoid fossils from Egypt (Kay and Simons) Tanzania (Stevens) and Myanmar (Gunnell and Ciochon). The chapter by John Oakley, Professor of Law at the University of California addresses the challenges to the teaching of evolution in schools- both public and universities world wide. Another major focus of several chapters are the primates of Madagascar. Two chapters are reviews of the extraordinary radiation of fossil lemurs (Godfrey et al, Jungers et al.). Two review the behavior and conservation of living lemurs (Taylor and Wright) and the chapter by Tattersall bridges the two major sections of the book by discussing about the biogeographic history of Malagasy mammals.
This revised edition will continue to serve as the most complete
and up-to-date guide to the use of the avian embryo in studies of
vertebrate development. It will include new approaches to analysis
of the chick genome, gene knock-out studies using RNA interference,
morpholinos, and other cutting edge techniques. As with the
original edition, emphasis has been placed on providing practical
guidance, highlighting potentials and pitfalls of all key cell
biological and embryological techniques.
Many hundreds of thousands suffer spinal cord injuries leading to
loss of sensation and motor function in the body below the point of
injury. Spinal cord research has made some significant strides
towards new treatment methods, and is a focus of many laboratories
worldwide. In addition, research on the involvement of the spinal
cord in pain and the abilities of nervous tissue in the spine to
regenerate has increasingly been on the forefront of biomedical
research in the past years. The Spinal Cord, a collaboration with
the Christopher and Dana Reeve Foundation, is the first
comprehensive book on the anatomy of the mammalian spinal cord.
Tens of thousands of articles and dozens of books are published on
this subject each year, and a great deal of experimental work has
been carried out on the rat spinal cord. Despite this, there is no
comprehensive and authoritative atlas of the mammalian spinal cord.
Almost all of the fine details of spinal cord anatomy must be
searched for in journal articles on particular subjects. This book
addresses this need by providing both a comprehensive reference on
the mammalian spinal cord and a comparative atlas of both rat and
mouse spinal cords in one convenient source. The book provides a
descriptive survey of the details of mammalian spinal cord anatomy,
focusing on the rat with many illustrations from the leading
experts in the field and atlases of the rat and the mouse spinal
cord. The rat and mouse spinal cord atlas chapters include
photographs of Nissl stained transverse sections from each of the
spinal cord segments (obtained from a single unfixed spinal cord),
detailed diagrams of each of the spinal cord segments pictured,
delineating the laminaeof Rexed and all other significant neuronal
groupings at each level and photographs of additional sections
displaying markers such as acetylcholinesterase (AChE), calbindin,
calretinin, choline acetlytransferase, neurofilament protein (SMI
32), enkephalin, calcitonin gene-related peptide (CGRP), and
neuronal nuclear protein (NeuN).
Recently, there has been an increased interest in research on personality, temperament, and behavioral syndromes (henceforth to be referred to as personality) in nonhuman primates and other animals. This follows, in part, from a general interest in the subject matter and the realization that individual differences, once consigned to error terms in statistical analyses, are potentially important predictors, moderators, and mediators of a wide variety of outcomes ranging from the results of experiments to health to enrichment programs. Unfortunately, while there is a burgeoning interest in the subject matter, findings have been reported in a diverse number of journals and most of the methodological and statistical approaches were developed in research on human personality. The proposed volume seeks to gather submissions from a variety of specialists in research on individual differences in primate temperament, personality, or behavioral syndromes. We anticipate that chapters will cover several areas. The first part of this edited volume will focus on methodological considerations including the advantages and disadvantages of different means of assessing these constructs in primates and introduce some statistical approaches that have typically been the domain of human personality research. Another part of this edited volume will focus on present findings including the physiological and genetic bases of personality dimensions in primates; the relationship between personality and age; how personality may moderate or impact various outcomes including behavior, health, and well-being in captive and non-captive environments. For the third part of the volume we hope to obtain summaries of the existing work of the authors on the evolutionary important of personality dimensions and guideposts for future directions in this new and exciting area of research."
Recent polls identify Jane Goodall to be the most recognizable
living scientist in the Western world. Her work with chimpanzees at
the Gombe Stream Reserve in Tanzania has been renowned as one of
the great achievements of scientific research. Her approach to
field study, once ridiculed and challenged by the scientific world,
has now become the model for other ethologists to use.
Geography, topography, weather patterns, and unique natural features make Cape May, New Jersey, one of the most important birding sites in North America. Throughout the year thousands of birders travel to Cape May from around the country--and across the ocean--to witness the arrival of tens of thousands of raptors, songbirds, shorebirds, and seabirds. In this guide, Cape May birders can find out exactly when and where in the region to go, what birds they're likely to see, why the birds are there, and what factors could affect the birds' behavior. Filled with the authors' photos, this book offers insider information that will help any birder make the most of a visit. It features a complete Cape May bird list and a description of the region's history complemented by images that show how Cape May has changed over the years, and how it has stayed the same.
