More Details..

Unlike any other book, Avian Cognition thoroughly examines avian intelligence, behavior, and individuality. Preferences, choices, motivation, and habits of species, flocks, and individual birds are discussed and compared. This book investigates who birds are and why they do what they do. Daily, seasonal, and play activities, creativity, reasoning abilities, problem-solving skills, social interaction, life stages, and communication patterns are described, and a distinction is made between vocalizations that are learned and those that are inherited. The behavior and intelligence of both wild and pet birds is compared, and unlike other books, entire chapters are devoted to a single species.

More Details..

Naturally occurring salt tolerant and halophytic plants (trees, shrubs, grasses, and forbs) have always been utilized by livestock as a supplement or drought reserve. Salt tolerant forage and fodder crops are now being planted over wide areas. Increasingly, large-scale production of fodder on formerly abandoned irrigated cropland has allowed salt tolerant and halophytic feedstuffs to be mainstreamed into the supply chain for feedlots. Feeding salty feeds to livestock has been evaluated in many countries with good outcomes especially as a way to improve livestock nutrition and productivity. Better ways have been devised to use these potentially valuable feed resources. These feedstuffs are best fed in mixed rations. Substituting conventional fodder with up to 30 percent of the diets comprising halophytic feedstuffs have proved most successful for ruminant livestock but special formulations have been devised for poultry and rabbits. There are big savings on the import of costly feedstuffs and benefits to livelihoods of those dependent on scattered, sparse and unreliable forage/fodder in the world’s drylands that cover about 40 percent of the world’s land surface.

This book is written by leading authorities from many different countries. It reviews past and current work on the animal-oriented aspects of the utilization of feedstuffs derived from salt tolerant and halophytic plants. It brings to the reader (scientist, researcher, academics and their students, policy makers, and livestock operators) an up-to-date analysis of the important issues related to salt-rich feedstuffs (nutrition, productivity, and reproduction).

More Details..

Suppose you were designing a marine mammal. What would you need to think about to allow it to live in the ocean? How would you keep it warm? What would you design to allow it to dive for very long periods to extreme depths? Where would it find water to drink? How would you minimize the cost of swimming, and how would it find its prey in the deep and dark? These questions and more are examined in detail throughout this book.

Marine Mammal Physiology: Requisites for Ocean Living is the first textbook focused on how marine mammals live in the sea from a physiological point of view. It explores the essential aspects of what makes a marine mammal different from terrestrial mammals, beyond just their environment. Unlike many publications and books that cover these species from almost all perspectives, this textbook takes a step back to focus on the physiological and biochemical characteristics that have allowed these mammals as a group to exploit effectively the marine environment that is so hostile to humans.

The chapter topics are grouped into major themes: diving and locomotion, nutrition and energetics, reproduction, sensory systems, and environmental interactions. Each chapter is arranged around a common perspective and theme: the big picture challenge and summary and what is known specifically by order. To aid you even further, the authors include a "Toolbox" section in each chapter where they discuss the newest methods for understanding and working on the physiology of marine mammals.

More Details..

A persistent argument among evolutionary biologists and philosophers revolves around the nature of natural selection. Evolution by Natural Selection: Confidence, Evidence and the Gap explores this argument by using a theory of persistence as an intentional foil to examine ways in which similar theories can be misunderstood. It discusses Charles Darwin’s theory of natural selection, including what the theory says, what it aims to explain, and how it manages to explain natural selection.

Darwin’s theory is so familiar today that it feels universally understood. However, the fact that there are so divergent views about the theory means that not everyone who thinks he or she understands it can be right. This book describes the history of evolutionary theory as a sequence of theoretical developments, not all of which can be considered improvements. In particular, it suggests that some attempts to use the theory of natural selection end up reshaping the concepts involved so that they can be applied more easily to the world. As a result, the theory is stripped of some of its explanatory power and becomes detached from the empiricism that good scientific examination requires.

With these issues in mind, Evolution by Natural Selection shows there are aspects of the theory of natural selection that are not totally understood. These misunderstandings create problems in uses of the theory. At a time when selectionist explanations are being brought forward to explain an ever-widening range of phenomena, this book analyzes the explanatory structure of Darwin’s theory. It takes a much-needed thoughtful look into the working parts of the theory of natural selection to provide better understanding of the theory and its role in contemporary science and life.

Dating back to the early Cambrian period, crustaceans had ample time to undertake endless experimentation with form and function. Today, no other group of plants or animals on the planet exhibit the range of morphological diversity seen among extant Crustacea. With more than 52,000 species, they are placed fourth in terms of overall species diversity. This book comprehensively elucidates the reproduction and development of all the taxonomic groups of Crustacea and bridges the gap between conventional zoologists and molecular biologists. Reproductive modes from the point of embryonic stem cells and primordial germ cells is discussed with a special section on cysts.

Despite their diversity, amphibians and reptiles (ARs) share many physiological traits of pivotal importance to their ability to cope with the physical environment, such as their dependence on external heat sources. Species distributed along a latitudinal or altitudinal gradient can exhibit considerable variation in their physiological capabilities as a function of changes in environmental parameters. This book provides a comprehensive and integrative view of the interplay between physiology and behavior in ARs, leading to a better understanding of the subject.

More Details..

The various species of new world blackbirds, often intermingled in large foraging flocks and nighttime roosts, collectively number in the hundreds of millions and are a dominant component of the natural and agricultural avifauna in North America today. Because of their abundance, conspicuous flocking behavior, and feeding habits, these species have often been in conflict with human endeavors.

The pioneering publications on blackbirds were by F. E. L. Beal in 1900 and A. A. Allen in 1914. These seminal treatises laid the foundation for more than 1,000 descriptive and experimental studies on the life histories of blackbirds as well as their ecology and management in relation to agricultural damage and other conflicts such as caused by large winter roosting congregations. The wealth of information generated in over a century of research is found in disparate outlets that include government reports, conference proceedings, peer-reviewed journals, monographs, and books.

For the first time, Ecology and Management of Blackbirds (Icteridae) in North America summarizes and synthesizes this vast body of information on the biology and life histories of blackbirds and their conflicts with humans into a single volume for researchers, wildlife managers, agriculturists, disease biologists, ornithologists, policy makers, and the public. The book reviews the life histories of red-winged blackbirds, yellow-headed blackbirds, common grackles, and brown-headed cowbirds. It provides in-depth coverage of the functional roles of blackbirds in natural and agricultural ecosystems. In doing so, this authoritative reference promotes the development of improved science-based, integrated management strategies to address conflicts when resolutions are needed.

More Details..

This book is perhaps the first attempt to comprehensively project the uniqueness of molluscs, covering almost all aspects of reproduction and development from aplacophorans to vampyromorphic cephalopods. Molluscs are unique for the presence of protective external shell, defensive inking, geographic distribution from the depth of 9,050 m to an altitude of 4,300 m, gamete diversity, the use of nurse eggs and embryos to accelerate the first few mitotic divisions in embryos, the natural occurrence of androgenics in a couple of bivalves, viable induced tetraploids, gigantism induced by elevated ploidy, the complementary role played by mitochondrial genome in sex determination by nuclear genes and the uptake and accumulation of steroid hormone from surrounding waters. In molluscs, sexuality comprises of gonochorism (< 75 %) and hermaphroditism, which itself includes simultaneous (> 24%), protandry (< 1 %), Marian and serial. In them, the presence of shell affords iteroparity and relatively longer life span in prosobranchs and bivalves but its absence semelparity and short life span in opisthobranchs and cephalopods. Within semelparity, gonochorism facilitates faster growth and larger body size but hermaphroditism small body size. In them, sex is irrevocably determined at fertilization by a few unknown genes and is not amenable to any environmental influence. However, the sex determining mechanism is more a family trait in bivalves. Primary sex differentiation is also fixed and not amenable to environmental factor but secondary differentiation is labile, protracted and amenable to environmental factors. Both sex differentiation and reproductive cycle are accomplished and controlled solely by neurohormones. In these processes, the role of steroid hormones may be alien to molluscs.

This book reviews and describes these strategies for nearly 200 species of birds from a 30-year study of Central Amazonian birds. Each account is to be illustrated with several color photos focusing on wing and tail feather molt.

Biology and Ecology of Edible Marine Bivalve Molluscs provides a plethora of first-hand information on the diversity, biology, and ecology of edible marine bivalve mollusks.

Marine bivalve molluscs play important roles in the marine ecosystems by filtering the water and serving as habitat and prey for a variety of sea life. Furthermore, by pumping large quantities of water through their bodies, they serve as good bio-indicators to monitor the health of the surrounding environment. This diverse group of species, estimated at about 9,200, inhabits virtually the entire world ocean, from the balmy tropics to the sub-zero Arctic, and from the deep ocean to sandy and rocky shorelines.

Among the marine bivalves, a total of 180 species (including mussels, oysters, scallops, cockles, and clams) have long been a part of the diet of coastal human populations. The National Oceanic and Atmospheric Administration estimated the 2011 economic value of commercial bivalve mollusc harvesting at about $1 billion annually in the U.S., and the weight of the harvest was estimated at 153.6 million pounds. Many species of marine bivalves are also commercially important for other purposes, such as pearls and shells for jewelry and decoration.

This comprehensive book on the biology and ecology of edible marine bivalve molluscs covers the biology of edible marine bivalves; profiles about 18o species, providing information on their habitat, distribution, morphology, food and feeding, reproduction, conservation status, etc.; discusses their nutritional values; examines their pharmaceutical values; and looks at their diseases and parasites. This abundance of knowledge is presented in an easy-to-read style with informative illustrations.

The volume, part of the Biology and Ecology of Marine Life book series, will be of great use for students and researchers of disciplines of fisheries science, marine biology, aquatic biology and fisheries and zoology. It will also serve as a standard reference book for the libraries of all universities and libraries.
