Most British birds of prey have largely recovered from historical persecution, but the beleaguered Hen Harrier is still struggling and remains far less common than it should be. This is a particular shame, because it is one of our most inspiring raptors. Spectacular sky-dancing displays and balletic food passes from male to female brighten up the moors in summer. And in winter, communal roosts in the lowlands attract birders from far and wide to catch sight of this now-elusive species. This book follows the Hen Harrier over a year: from rearing young hidden away in dense heather, to the fight for survival in the harshest months of winter. Interspersed among the monthly accounts are chapters on the history and status of this iconic bird, as well as an overview of one of the most intractable conflicts in modern conservation: the Hen Harrier’s liking for grouse moors (and the Red Grouse that live there) wins it few friends among shooters, and ongoing persecution continues to hamper its recovery. There are tentative signs of progress, but its fate as a breeding bird in England hangs in the balance.  Evocative illustrations, in part based on privileged access to the handful of breeding birds that remain on England’s moors, showcase the Hen Harrier’s exploits through the seasons. These will delight admirers of this species and hopefully foster a greater interest in its wellbeing. The Hen Harrier needs all the help it can get.
Various brain areas of mammals can phyletically be traced back to homologous structures in amphibians. The amphibian brain may thus be regarded as a kind of "microcosm" of the highly complex primate brain, as far as certain homologous structures, sensory functions, and assigned ballistic (pre-planned and pre-pro grammed) motor and behavioral processes are concerned. A variety of fundamental operations that underlie perception, cognition, sensorimotor transformation and its modulation appear to proceed in primate's brain in a way understandable in terms of basic principles which can be investigated more easily by experiments in amphibians. We have learned that progress in the quantitative description and evaluation of these principles can be obtained with guidance from theory. Modeling - supported by simulation - is a process of transforming abstract theory derived from data into testable structures. Where empirical data are lacking or are difficult to obtain because of structural constraints, the modeler makes assumptions and approximations that, by themselves, are a source of hypotheses. If a neural model is then tied to empirical data, it can be used to predict results and hence again to become subject to experimental tests whose resulting data in tum will lead to further improvements of the model. By means of our present models of visuomotor coordination and its modulation by state-dependent inputs, we are just beginning to simulate and analyze how external information is represented within different brain structures and how these structures use these operations to control adaptive behavior."
Southern African Mammals Made Simple enables users to distinguish between commonly confused mammals by applying the breakthrough methodology that made Southern African LBJs Made Simple so hugely popular. The simple three-step system allows for quick and certain identification of mammals in the field. For each species featured, the book gives: - range maps - full-colour illustrations and photographs - key identification pointers, and - concise text describing height, weight, habits and habitat. All of southern Africa’s most common and distinctive mammals are included, but the particular value of this book lies in separating the more challenging species, such as antelope, mongooses, genets, primates and many more. It will appeal to both local and foreign visitors to our game parks.

This book is a collection of comprehensive and latest information on all aspects of vaccination in fish and shellfish. It provides the basic understanding about the immune system of both fish and crustaceans, besides giving the latest information on adjuvants, vaccine delivery methods, adverse effects of vaccines and methods to assess the efficacy of vaccines. Separate chapters on the role of pattern recognition receptors and interferons in fish vaccination, biofilm vaccines and biosafety and regulatory requirements for fish vaccines are also included. Aquaculture, being the fastest growing food producing industry in the world, is looked upon for alleviating the malnutrition especially among the under privileged population. However, intensive aquaculture practices have led to increased incidences of diseases and significant production losses. Among various health management measures employed in aquaculture, vaccination has been proven to be the best approach to protect fish against pathogens. It is considered to be safe and is a key factor for sustainable aquaculture. In this background, apart from the basic understanding of fish and shellfish immune system, updated knowledge on various types of vaccines and the vaccination strategies currently employed in aquaculture are also covered. The book is designed to provide the latest and comprehensive knowledge on all these aspects as a compiled resource material which is useful to students, researchers and other professionals in the field of aquaculture.

From the author of the National Book Award Finalist The Soul of an Octopus. Meet the ladies: a flock of smart, affectionate, highly individualistic chickens who visit their favorite neighbors, devise different ways to hide from foxes, and mob the author like she's a rock star. In these pages you'll also meet Maya and Zuni, two orphaned baby hummingbirds who hatched from eggs the size of navy beans, and who are little more than air bubbles fringed with feathers. Their lives hang precariously in the balance--but with human help, they may one day conquer the sky. Snowball is a cockatoo whose dance video went viral on YouTube and who's now teaching schoolchildren how to dance. You'll meet Harris's hawks named Fire and Smoke. And you'll come to know and love a host of other avian characters who will change your mind forever about who birds really are. Each of these birds shows a different and utterly surprising aspect of what makes a bird a bird--and these are the lessons of Birdology: that birds are far stranger, more wondrous, and at the same time more like us than we might have dared to imagine. In Birdology, beloved author of The Good Good Pig Sy Montgomery explores the essence of the otherworldly creatures we see every day. By way of her adventures with seven birds--wild, tame, exotic, and common--she weaves new scientific insights and narrative to reveal seven kernels of bird wisdom. The first lesson of Birdology is that, no matter how common they are, Birds Are Individuals, as each of Montgomery's distinctive Ladies clearly shows. In the leech-infested rain forest of Queensland, you'll come face to face with a cassowary--a 150-pound, man-tall, flightless bird with a helmet of bone on its head and a slashing razor-like toenail with which it (occasionally) eviscerates people--proof that Birds Are Dinosaurs. You'll learn from hawks that Birds Are Fierce; from pigeons, how Birds Find Their Way Home; from parrots, what it means that Birds Can Talk; and from 50,000 crows who moved into a small city's downtown, that Birds Are Everywhere. They are the winged aliens who surround us. Birdology explains just how very other birds are: Their hearts look like those of crocodiles. They are covered with modified scales, which are called feathers. Their bones are hollow. Their bodies are permeated with extensive air sacs. They have no hands. They give birth to eggs. Yet despite birds' and humans' disparate evolutionary paths, we share emotional and intellectual abilities that allow us to communicate and even form deep bonds. When we begin to comprehend who birds really are, we deepen our capacity to approach, understand, and love these otherworldly creatures. And this, ultimately, is the priceless lesson of Birdology: it communicates a heartfelt fascination and awe for birds and restores our connection to these complex, mysterious fellow creatures.
Those who have been privileged to watch baboons long enough to know them as individuals and who have learned to interpret some of their more subtle interactions will attest that the rapid flow of baboon behavior can at times be overwhelming. In fact, some of the most sophisticated and influential observation methods for sampling vertebrate social behavior grew out of baboon studies, invented by scientists who were trying to cope with the intricacies of baboon behavior. Barbara Smuts' eloquent study of baboons reveals a new depth to their behavior and extends the theories needed to account for it. While adhering to the most scrupulous methodological strictures, the author maintains an open research strategy--respecting her subjects by approaching them with the open mind of an ethnographer and immersing herself in the complexities of baboon social life before formulating her research design, allowing her to detect and document a new level of subtlety in their behavior. At the Gilgil site, described in this book, she could stroll and sit within a few feet of her subjects. By maintaining such proximity she was able to watch and listen to intimate exchanges within the troop; she was able, in other words, to shift the baboons well along the continuum from "subject" to "informant." By doing so she has illuminated new networks of special relationships in baboons. This empirical contribution accompanies theoretical insights that not only help to explain many of the inconsistencies of previous studies but also provide the foundation for a whole new dimension in the study of primate behavior: analysis oft he dynamics of long-term, intimate relationships and their evolutionary significance. At every stage of research human observers have underestimated the baboon. These intelligent, curious, emotional, and long-lived creatures are capable of employing stratagems and forming relationships that are not easily detected by traditional research methods. In the process of unraveling their complex social relationships, Smuts has revealed that these masters of strategy and aggressive competition are equally capable of patience, tenderness, and concern. "Barbara B. Smuts" is professor of psychology and anthropology, University of Michigan, Ann Arbor. She is also the author of Primate Societies.

This guide provides descriptions of when the bat species resident in Britain and Ireland use natural and human-made rock habitats, how they use them, and the environments each species occupies therein. For the first time it brings together findings from historical scientific investigations, useful photographic accounts and open-access biological records, along with a rich seam of new data – all in a practical and user-friendly structure. The book encompasses: ~ Descriptions of the features that a climber, caver or professional ecologist might encounter on and in rock habitats where bats roost. ~ Recording criteria for both the physical and environmental attributes of different features and situations. ~ Identification of suitability thresholds against which the recorded information can be compared to assess the likelihood that a specific feature might be exploited by a particular bat species. ~ Suggestions for how to avoid mistakes and difficulties when performing a survey. The intention is that using this book will help generate standardised biological records which can feed into the fully accessible online database at www.batrockhabitatkey.co.uk. These data will be analysed to search for patterns that can increase the confidence in the suitability thresholds and help build roost features that deliver the environment each species really needs. As well as offering many new insights, this book allows the reader to participate in cutting-edge research.

The use of DNA and other biological macromolecules has
revolutionized systematic studies of evolutionary history. Methods
that use sequences of nucleotides and amino acids are now routinely
used as data for addressing evolutionary questions that, although
not new questions, have defied description and analysis. The
world-renowned contributors use these new methods to unravel
particular aspects of the evolutionary history of birds. Avian
Molecular Evolution and Systematics presents an overview of the
theory and application of molecular systematics, focusing on the
phylogeny and evolutionary biology of birds. New, developing areas
in the phylogeny of birds at multiple taxonomic areas are covered,
as well as methods of analysis for molecular data, evolutionary
genetics within and between bird populations, and the application
of molecular-based phylogenies to broader questions of evolution.
Amagama Izinyoni: Zulu Names of Birds lists all the bird species found in KwaZulu-Natal and surrounds, gives the proposed standardised Zulu name for each species, and explains the underlying meaning and how the name came into being. All earlier names for these birds, even if no longer in current use, have been recorded here, making this a historical repository of Zulu bird names as well. This book is the result of the six-year Zulu Bird Name Project. Between 2013 and 2018, annual workshops, organised and facilitated by the three authors, brought together a total of eighteen mother-tongue Zulu-speaking bird experts to research the names of bird species present in the Zulu-speaking area of South Africa. At the start of the project, only approximately 40 per cent of the bird species of this area had species-specific Zulu names; by the end of the project all 550 species had unique names. The comprehensive introduction explains the methodology used in the Zulu bird name workshops, providing a template for linguists and ornithologists who might wish to do similar bird-naming exercises in the other African languages of southern Africa. The introduction also provides some linguistic and onomastic insights into bird naming generally and Zulu bird names in particular.
"Night-attack of wolves in Mongolia." "Nearly fatal combat with a kangaroo." "Comic scenes with the Elephant." "Captain Herriman examines a supposed Sea-serpent." This charming book, published by British naturalist PHILIP HENRY GOSSE (1810-1888) in 1860, was a best seller in its day, and no wonder: this is a passionate around-the-world journey through nature both wild and serene... and mysterious. "In the annals of cryptozoology," says cryptozoologist Loren Coleman in his new introduction, "Gosse is credited as one of the grandfathers of the discipline... In this book, one finds his records of the sea serpent, giant snakes, African unicorn, South America ape, and Ceylonese devil-bird, reflecting this early interest in romantic zoology, the precursor of cryptozoology." This new edition, complete with the original elegant illustrations, is part of Cosimo's Loren Coleman Presents series. LOREN COLEMAN is author of numerous books of cryptozoology, including BIGFOOT : The True Story of Apes in America, and Mothman and Other Curious Encounters.
This book has the modest aim of bringing together methodological, theo- retical, and empirical studies that bear on the phylogenetic placement of primates and their relatives, and continues a tradition started by Phylogeny of the Primates: A Multidisciplinary Approach (edited by W. P. Luckett and F. S. Szalay; Plenum Press, 1975) and The Comparative Biology and Evolutionary Rela- tionships of Tree Shrews (edited by W. P. Luckett, Plenum Press, 1980). Although there are several recent compendia of studies of primate relationships, most of these are exclusively concerned with the internal arrangement of clades within the order, not with the place of primates and their relatives on the eutherian cladogram. Evolutionary theory predicts that primates must be more closely related to some non primate mammals than to others, but a continuing problem has been to find reliable procedures for recovering historical relationships among taxa. Before the 1970s, higher-level relationships among primates and euthe- rian mammals that might be closely related to them were rarely treated in detail. Outstanding exceptions, like Le Gros Clark's Antecedents of Man, were just that-exceptions. (Clark himself essentially stopped with making a case for tree shrews; he did not, for example, explore whether bats and colugos were also related to primates. ) In the 1970s and 1980s, the rise of cladistic techniques and advances in molecular methods began to transform primate systematics.
The book aims at synthesizing our current knowledge of Acipenser sturio and its management. This species, one of the most widespread sturgeon species all over Western Europe ranging from the Black Sea to the Baltic, is now on the verge of extinction. Major aspects of its biology and management, including mismanagement, are provided in a historic perspective. Similarly, the changes in the restoration programs (in situ and ex situ) initiated in France and Germany are presented. As the species occurred in sympatry with Acipenser oxyrinchus in Germany and Poland and very recently in France as well, a brief outlook on restoration-management programs of A. oxyrinchus are also provided for both North America and Northern European countries, namely Germany and Poland. As conservation-restoration actions go beyond scientific issues, non-governmental stakeholders and marine professional fishermen's organizations have also been asked to contribute, and the key role of a French-German cooperation plan is underlined. A part of the book is devoted to perspectives. Illustrations of the European sturgeon, mainly in photographs, but also in stamps and paintings, are presented.
These fun, fact-filled books are perfect for young researchers. The history, geography, and people of each state are covered in these books. The text is enhanced with maps, photos, and graphs. Timelines and fast-facts sections reinforce the text. The detailed and well-written books are ideal for both research and entertainment. |
