Morphological Variation

Morphological Variation PDF Author: Antje Dammel
Publisher: John Benjamins Publishing Company
ISBN: 902726256X
Category : Language Arts & Disciplines
Languages : en
Pages : 353

Book Description
Morphological variation is a rather young, yet fascinating topic to study in its own right because it offers challenging evidence both for the autonomy of morphology (morphomic processes) as well as for its tight interconnection with other grammatical domains, notably phonology and syntax. Covering a wide range of phenomena (e.g. negation structures, form function-mismatches in the verbal and nominal domain, loss of morphosyntactic feature values, etc.), the contributions to this volume combine in-depth empirical studies with the explanatory potential of modern theories of grammar as well as approaches for capturing and modelling microtypological diversity.

Development and Distribution of Discontinuous Morphological Variation of the Human Infracranial Skeleton

Development and Distribution of Discontinuous Morphological Variation of the Human Infracranial Skeleton PDF Author: Shelley Rae Saunders
Publisher: University of Ottawa Press
ISBN: 1772820768
Category : Social Science
Languages : en
Pages : 573

Book Description
Over 1,400 individual skeletons from three major skeletal populations were examined for a series of approximately fifty infracranial non-metric traits. Trait frequencies are studied for size, sex and age differences, trait intercorrelations, and association with bone robusticity. Skeletal population studies are performed using various combinations of the traits and two distance statistics.

Book Description
"The study reported here explores the possibilities of investigating the important question of genetic and environmental interaction by genetic methods utilizing the techniques of morphological description and measurement. The complex nature of man's genetic variation and some of the problems which are unique to human studies are reviewed. The twin method is then evaluated, within the context of our understanding of the phenomenon of human twinning, for its usefulness in detecting genetic variability and analyzing genetic and environmental interaction. With this background, the twin method is then applied to the study of different descriptions and measurements of morphological variation. Because this is a preliminary study, emphasis has been placed upon the methods of investigation and upon providing an empirical basis for the application of genetic and morphological studies to different human problems. It is hoped that the methods presented here and the results of this analysis will suggest further twin research and morphological studies in genetics, anthropology, and the medical sciences. While the present study was designed for the analysis of genetic and environmental effects on what may be termed "normal" morphological variation, selection of the subjects on the basis of medical histories and examinations has made it possible to extend considerably the scope of the investigation. Most of the data relating to medical information have been reported elsewhere. Those aspects which have a bearing on the evaluation of the twin method or the analysis of morphological variables are reported here. Extensive data available from the records of the Columbia-Presbyterian Medical Center also have been incorporated. The Twin Study Project was carried out under the auspices of the Institute for the Study of Human Variation in Columbia University, and was conducted within the facilities of the Columbia-Presbyterian Medical Center. The collection of the data was started in September 1952 with a poll of all new admissions to Vanderbilt Clinic, for twins; it was completed in March 1956"--Preface.

Variation and Change in Morphology

Variation and Change in Morphology PDF Author: Franz Rainer
Publisher: John Benjamins Publishing
ISBN: 9027288526
Category : Language Arts & Disciplines
Languages : en
Pages : 259

Book Description
The papers in this volume derive from the 13th International Morphology Meeting (Vienna 2008). They all address the main topic of the meeting, viz. variation and change in morphology. Inflectional and derivational morphology are represented on equal terms. The focus is on cases of language-internal variation, such as pattern competition, base variation, form–function mismatches, or morphological pleonasm. Other recurring themes are language contact as a cause of variation, the output-orientedness of morphological patterns, and linguistic economy.The contributions cover a wide variety of languages, both Indo-European (Romance, Germanic and Slavic; Latin, Lithuanian and Romani) and non-Indo-European (Hungarian, Maay, Chinese).

Bird Species

Bird Species PDF Author: Dieter Thomas Tietze
Publisher: Springer
ISBN: 3319916890
Category : Science
Languages : en
Pages : 266

Book Description
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.

Variation

Variation PDF Author: Benedikt Hallgrímsson
Publisher: Elsevier
ISBN: 9780080454467
Category : Science
Languages : en
Pages : 592

Book Description
Darwin's theory of evolution by natural selection was based on the observation that there is variation between individuals within the same species. This fundamental observation is a central concept in evolutionary biology. However, variation is only rarely treated directly. It has remained peripheral to the study of mechanisms of evolutionary change. The explosion of knowledge in genetics, developmental biology, and the ongoing synthesis of evolutionary and developmental biology has made it possible for us to study the factors that limit, enhance, or structure variation at the level of an animals' physical appearance and behavior. Knowledge of the significance of variability is crucial to this emerging synthesis. Variation situates the role of variability within this broad framework, bringing variation back to the center of the evolutionary stage. Provides an overview of current thinking on variation in evolutionary biology, functional morphology, and evolutionary developmental biology Written by a team of leading scholars specializing on the study of variation Reviews of statistical analysis of variation by leading authorities Key chapters focus on the role of the study of phenotypic variation for evolutionary, developmental, and post-genomic biology
