Book Description
This book provides fundamental information on pet birds, menaces, and advances made in the diagnosis and treatment of menaces. It is the only book covering all species of pet birds, menaces and their individual management. The handful of related books available worldwide are largely outdated and focus on a single species or breed of pet bird. The book encompasses the history of bird keeping, common breeds of birds, their nutritional requirements, list of zoonotic diseases transmitted by birds and guideline for their prevention. It covers infectious, non-infectious clinical and metabolic diseases, and toxicity in detail with a special focus on the history of diseases, etiology, affected hosts, pathogenesis, clinical signs, diagnosis and treatment. Separate chapters detail relevant diagnostic techniques, management and care practices, including updated information. The book offers an invaluable guide for students and teachers in the field of (avian) veterinary medicine, scientists/research scholars working in related fields, and avian medicine practitioners, as well as all those progressive bird owners who want to know the basics of their care and management.

Book Description
Being both broad - perception and motor organization - and narrow - just onegroup of animals - at the same time, this book presents a new unified framework for understanding perceptuomotor organization, stressing the importance of an ecological perspective. Section I reviews recent research on a variety of sensory and perceptual processes in birds, which all involve subtle analyses of the relationships between species' perceptual mechanisms and their ecology and behaviour. Section II describes the variousresearch approaches - behavioural, neurophysiological, anatomical and comparative - all dealing with the common problem of understanding how the activities of large numbers of muscles are coordinated to generate adaptive behaviour. Section III is concerned with a range of approaches to analyzing the links between perceptual and motor processes, through cybernetic modelling, neurophysiological analysis, and behavioural methods.

Book Description
Ecotoxicology is a relatively new scientific discipline. Indeed, it might be argued that it is only during the last 5-10 years that it has come to merit being regarded as a true science, rather than a collection of procedures for protecting the environment through management and monitoring of pollutant discharges into the environment. The term 'ecotoxicology' was first coined in the late sixties by Prof. Truhaut, a toxicologist who had the vision to recognize the importance of investigating the fate and effects of chemicals in ecosystems. At that time, ecotoxicology was considered a sub-discipline of medical toxicology. Subsequently, several attempts have been made to portray ecotoxicology in a more realistic light. Notably, both F. Moriarty (1988) and F. Ramade (1987) emphasized in their books the broad basis of ecotoxicology, encompassing chemical and radiation effects on all components of ecosystems. In doing so, they and others have shifted concern from direct chemical toxicity to man, to the far more subtle effects that pollutant chemicals exert on natural biota. Such effects potentially threaten the existence of all life on Earth. Although I have identified the sixties as the era when ecotoxicology was first conceived as a coherent subject area, it is important to acknowledge that studies that would now be regarded as ecotoxicological are much older. Wherever people's ingenuity has led them to change the face of nature significantly, it has not escaped them that a number of biological con sequences, often unfavourable, ensue.

Book Description
This volume focuses on those instances when benign and even beneficial relationships between microbes and their hosts opportunistically change and become detrimental toward the host. It examines the triggering events which can factor into these changes, such as reduction in the host’s capacity for mounting an effective defensive response due to nutritional deprivation, coinfections and seemingly subtle environmental influences like the amounts of sunlight, temperature, and either water or air quality. The effects of environmental changes can be compounded when they necessitate a physical relocation of species, in turn changing the probability of encounter between microbe and host. The change also can result when pathogens, including virus species, either have modified the opportunist or attacked the host’s protective natural microflora. The authors discuss these opportunistic interactions and assess their outcomes in both aquatic as well as terrestrial ecosystems, highlighting the impact on plant, invertebrate and vertebrate hosts.

Book Description
Detailed information dealing with the ecology of mycobacteria is derived from a variety of different scientific fields such as botany, biochemistry, genetics, immunology, microbiology and epidemiology. This is the first attempt to evaluate this information from an ecological point of view and to develop a strategy for the prevention of tuberculosis and other mycobacterioses based on the ecological behavior of mycobacteria, especially the potentially pathogenic species capable of either growth in the environment or provoking disease. Regarding the interests of the developing countries, special attention is paid to the ecology of Mycobacterium leprae and to the supporting effect of accompanying mycobacteria in its pathogenicity. On a more positive side, environmental mycobacteria play an important role in the ecology of moorland dragonflies. Such a book is needed for specialists working in the field of mycobacterial research, clinical laboratories, the public health service, food hygiene, the water industry and in general ecology.

Book Description
This book covers advances made since the 2004 Springer volume “Polarized Light in Animal Vision” edited by Horvath and Varju, but also provides reviews and synopses of some areas. Part I examines polarization sensitivity across many animal taxa including vertebrates and invertebrates and details both terrestrial and aquatic life. Part II is devoted to the description of polarized light in nature and explores how the physics of light must be taken into account when understanding how polarized light is detected by the visual system. This includes underwater polarization due to scattering; polarization patterns reflected from freshwater bodies; polarization characteristics of forest canopies; normal and anomalous polarization patterns of the skies; skylight polarization transmitted through Snell’s window and both linearly and circularly polarized signals produced by terrestrial and aquatic animals. This Part also examines polarized “light pollution” induced by anthropogenic factors such as reflection off asphalt surfaces, glass panes, car bodies, and other man-made structures that are now known to form ecological traps for polarotactic insects. Part III surveys some of the practical applications of polarization vision including polarization-based traps for biting insects, ground-based polarimetric cloud detectors and an historical examination of the navigational abilities of Viking seafarers using the sky polarization compass. The deterrent qualities of ungulate pelage to polarization-sensitive biting insects is also examined in this section.
