Download or read book Bird Species written by Dieter Thomas Tietze and published by Springer. This book was released on 2018-11-19 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The average person can name more bird species than they think, but do we really know what a bird “species” is? This open access book takes up several fascinating aspects of bird life to elucidate this basic concept in biology. From genetic and physiological basics to the phenomena of bird song and bird migration, it analyzes various interactions of birds – with their environment and other birds. Lastly, it shows imminent threats to birds in the Anthropocene, the era of global human impact. Although it seemed to be easy to define bird species, the advent of modern methods has challenged species definition and led to a multidisciplinary approach to classifying birds. One outstanding new toolbox comes with the more and more reasonably priced acquisition of whole-genome sequences that allow causative analyses of how bird species diversify. Speciation has reached a final stage when daughter species are reproductively isolated, but this stage is not easily detectable from the phenotype we observe. Culturally transmitted traits such as bird song seem to speed up speciation processes, while another behavioral trait, migration, helps birds to find food resources, and also coincides with higher chances of reaching new, inhabitable areas. In general, distribution is a major key to understanding speciation in birds. Examples of ecological speciation can be found in birds, and the constant interaction of birds with their biotic environment also contributes to evolutionary changes. In the Anthropocene, birds are confronted with rapid changes that are highly threatening for some species. Climate change forces birds to move their ranges, but may also disrupt well-established interactions between climate, vegetation, and food sources. This book brings together various disciplines involved in observing bird species come into existence, modify, and vanish. It is a rich resource for bird enthusiasts who want to understand various processes at the cutting edge of current research in more detail. At the same time it offers students the opportunity to see primarily unconnected, but booming big-data approaches such as genomics and biogeography meet in a topic of broad interest. Lastly, the book enables conservationists to better understand the uncertainties surrounding “species” as entities of protection.

Download or read book Effect of Heavy Metal Pollution on Plants written by N. W. Lepp and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace metals occur as natural constituents of the earth's crust, and are ever present constituents of soils, natural waters and living matter. The biological significance of this disparate assemblage of elements has gradually been uncovered during the twentieth century; the resultant picture is one of ever-increasing complexity. Several of these elements have been demonstrated to be essential to the functions of living organisms, others appear to only interact with living matter in a toxic manner, whilst an ever-decreasing number do not fall conveniently into either category. When the interactions between trace metals and plants are considered, one must take full account of the known chemical properties of each element. Consideration must be given to differences in chemical reactivity, solubility and to interactions with other inorganic and organic molecules. A clear understanding of the basic chemical properties of an element of interest is an essential pre-requisite to any subsequent consideration of its biological significance. Due consideration to basic chemical considerations is a theme which runs through the collection of chapters in both volumes.
Download or read book Protective Groups in Organic Chemistry written by J. McOmie and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past decade there has been a great increase in the use of protective groups, especially in the synthesis of large and complex organic molecules. Perhaps the greatest activity has been in the peptide field where such triumphs as the total synthesis of insulin and of bovine ribonuclease (molecular weight 13,700) have been achieved. Correspondingly, more protective groups have been devised for the protection of amino and imino groups than for any other functional group. There are many reviews and books on the synthesis of pep tides but there has been no general survey of protective groups since my 1 own review in 1963. At that time the five main methods for the removal of protective groups involved acid or base hydroly sis, reduction, oxidation, or thermal elimination reactions. Recent advances include the use of photo-sensitive and metal ion sensitive protective groups, and the attachment of functional groups to reactive polymers as a method of protec tion during the solid-phase synthesis of peptides and poly nucleotides. Another interesting development is the design and use of protective groups with a built-in 'safety-catch', which can be 'released' by a specific chemical reaction, so that an otherwise stable bond is made labile at the appropriate moment thereby allowing the protective group to be removed under very 2 mild conditions. My own interest in protective groups dates from 1944 when, as a student, I gave two lectures on the subject and produced an 11 page review including 70 references.
Download or read book Dermatoglyphics in Medical Disorders written by B. Schaumann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The skin on the fingertips and palmar and plantar surfaces of man is not smooth. It is grooved by curious ridges, which form a variety of configurations. These ridge configurations have attracted the at tention of laymen for millenia. They have also evoked the serious interest of scientists for more than three centuries. The anatomist Bidloo provided a description of ridge detail in the seventeenth cen tury. Since then, additional information has been added by anthro pologists, biologists, and geneticists. For the last century, the fact that each individual's ridge configurations are unique has been uti lized as a means of personal identification especially by law enforce ment officials. Widespread medical interest in epidermal ridges de veloped only in the last several decades when it became apparent that many patients with chromosomal aberrations had unusual ridge formations. Inspection of skin ridges, therefore, promised to provide a simple, inexpensive means for determining whether a given patient had a particular chromosomal defect. However, the promise was only partially fulfilled because of the inherent variability of skin ridge configurations. It was possible to draw conclusions about ridge ab normalities in groups of patients but not always in a given individual. Patients and clinicians became somewhat disenchanted with the clinical value of studying ridges.
