Download or read book On the Origin of Species Through Heteropatric Differentiation written by Kevin Winker and published by Univ of California Press. This book was released on 2010-11 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Differentiation and speciation without extended isolation appear to be common among migratory animals. Historical oversight of this is probably due to temporal distortion in distribution maps and a tendency to consider that lineages had different historical traits, such as being sedentary or much less mobile. Mobility among cyclic migrants makes population isolation difficult, and diminished levels of intraspecific differentiation occur in avian migrants (I term this "Montgomery's rule"). Nevertheless, many lineages have differentiated despite increased mobility and a high propensity for gene flow, conditions that speciation theory has not addressed adequately. Populations of seasonal migrants usually occur in allopatry and sympatry during a migratory cycle, and this distributional pattern (heteropatry) is the focus of a model empirically developed to explain differentiation in migratory lineages. Divergence arises through disruptive selection from resource competition and heterogeneously distributed cyclic resources. Heteropatric speciation is a type of ecological speciation in which reproductive isolation increases between populations as a byproduct of adaptation to different environments that enhances breeding allopatry and allochrony despite degrees of sympatry that occur during the nonbreeding period in migration cycles. Mating or pair bonding in nonbreeding areas is rare. Patterns such as leapfrog migration and limited morphological divergence suggest that differentiation is driven by these ecological factors rather than by sexual selection or nontemporal changes in the resource base itself, although the additional presence of either of the latter would have additive divergent effects. Migratory lineages provide a largely neglected series of natural experiments in speciation in which to test predictions stemming from this model and others focusing on ecological speciation --
Book Synopsis The Avian Migrant by : John H. Rappole
Download or read book The Avian Migrant written by John H. Rappole and published by Columbia University Press. This book was released on 2013-06-11 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of migration, regardless of the distance involved, is to exploit two or more environments suitable for survival or reproduction over time, usually on a seasonal basis. Yet individual organisms can practice the phenomenon differently, and birds deploy unique patterns of movement over particular segments of time. Incorporating the latest research on bird migration, this concise, critical assessment offers contemporary readers a firm grasp of what defines an avian migrant, how the organism came to be, what is known about its behavior, and how we can resolve its enduring mysteries. John H. Rappole's sophisticated survey of field data clarifies key ecological, biological, physiological, navigational, and evolutionary concerns. He begins with the very first migrants, who traded a home environment of greater stability for one of greater seasonality, and uses the structure of the annual cycle to examine the difference between migratory birds and their resident counterparts. He ultimately connects these differences to evolutionary milestones that have shaped a migrant lifestyle through natural selection. Rather than catalogue and describe various aspects of bird migration, Rappole considers how the avian migrant fits within a larger ecological frame, enabling a richer understanding of the phenomenon and its critical role in sustaining a hospitable and productive environment. Rappole concludes with a focus on population biology and conservation across time periods, considering the link between bird migration and the spread of disease among birds and humans, and the effects of global warming on migrant breeding ranges, reaction norms, and macroecology.
Book Synopsis Behavioural and Ecological Consequences of Urban Life in Birds by : Caroline Isaksson
Download or read book Behavioural and Ecological Consequences of Urban Life in Birds written by Caroline Isaksson and published by Frontiers Media SA. This book was released on 2018-06-19 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urbanization is next to global warming the largest threat to biodiversity. Indeed, it is becoming increasingly evident that many bird species get locally extinct as a result of urban development. However, many bird species benefit from urbanization, especially through the abundance of human-provided resources, and increase in abundance and densities. These birds are intriguing to study in relation to its resilience and adaption to urban environments, but also in relation to its susceptibility and the potential costs of urban life. This Research Topic consisting of 30 articles (one review, two meta-analyzes and 27 original data papers) provides insights into species and population responses to urbanization through diverse lenses, including biogeography, community ecology, behaviour, life history evolution, and physiology.
Download or read book Snowbird written by Ellen D. Ketterson and published by University of Chicago Press. This book was released on 2016-03-30 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most familiar North American birds, the snowbird, otherwise known as the Dark-eyed Junco, can be seen darting across forest floors, pecking at suburban birdfeeders, and foraging at the edges of parks, streams, and roads all across the continent. By one estimate, upwards of 630 million Juncos populate North America: twice the number of people living here in the U.S. No Bird Like the Snowbird: Integrative Approaches to Understanding Evolutionary Diversity in the Avian Genus Junco presents diverse expertise not just on the Dark-eyed Junco, but on the Junco genus more broadly. Collectively, the contributors draw on research, methods, and findings from organismal biology and evolutionary biology in order to show how juncos match their physiology and behavior to their environment via endocrine and timing mechanisms, and how Junco evolutionary history can provide insight into population divergence and the formation of new species. In so doing, they not only provide a definitive account of the Junco genus and speak to the its continuing importance as a model organism in a time of rapid global change, they also merge two major biological fields that are typically kept apart, with the goal of offering biologists an integrative framework for further studies into adaptation and population divergence.
Book Synopsis Speciation in Birds by : Trevor Price
Download or read book Speciation in Birds written by Trevor Price and published by Roberts. This book was released on 2008 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Speciation in Birds, Trevor Price, a University of Chicago professor and leading expert in the field, has written the most authoritative and modern synthesis on the subject to date. In clear and engaging prose and through beautiful illustrations, Price shows us why the field is as exciting and vibrant as ever. He evaluates the roles of natural selection and sexual selection. He asks how speciation contributes to some of the great patterns in species diversity such as the large number of species in the tropics, and the many endemic species on isolated islands. Throughout the book, Price emphasizes the integration of behavior, ecology, and genetics.
Book Synopsis Assumptions Inhibiting Progress in Comparative Biology by : Brian I. Crother
Download or read book Assumptions Inhibiting Progress in Comparative Biology written by Brian I. Crother and published by CRC Press. This book was released on 2016-11-18 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a thought-provoking assessment of assumptions inhibiting progress in comparative biology. The volume is inspired by a list generated years earlier by Donn Rosen, one of the most influential, innovative and productive comparative biologists of the latter 20th century. His list has assumed almost legendary status among comparative evolutionary biologists. Surprisingly many of the obstructing assumptions implicated by Rosen remain relevant today. Any comparative biologist hoping to avoid such assumptions in their own research will benefit from this introspective volume.
Download or read book Phylogenetics written by E. O. Wiley and published by John Wiley & Sons. This book was released on 2011-10-11 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: The long-awaited revision of the industry standard on phylogenetics Since the publication of the first edition of this landmark volume more than twenty-five years ago, phylogenetic systematics has taken its place as the dominant paradigm of systematic biology. It has profoundly influenced the way scientists study evolution, and has seen many theoretical and technical advances as the field has continued to grow. It goes almost without saying that the next twenty-five years of phylogenetic research will prove as fascinating as the first, with many exciting developments yet to come. This new edition of Phylogenetics captures the very essence of this rapidly evolving discipline. Written for the practicing systematist and phylogeneticist, it addresses both the philosophical and technical issues of the field, as well as surveys general practices in taxonomy. Major sections of the book deal with the nature of species and higher taxa, homology and characters, trees and tree graphs, and biogeography—the purpose being to develop biologically relevant species, character, tree, and biogeographic concepts that can be applied fruitfully to phylogenetics. The book then turns its focus to phylogenetic trees, including an in-depth guide to tree-building algorithms. Additional coverage includes: Parsimony and parsimony analysis Parametric phylogenetics including maximum likelihood and Bayesian approaches Phylogenetic classification Critiques of evolutionary taxonomy, phenetics, and transformed cladistics Specimen selection, field collecting, and curating Systematic publication and the rules of nomenclature Providing a thorough synthesis of the field, this important update to Phylogenetics is essential for students and researchers in the areas of evolutionary biology, molecular evolution, genetics and evolutionary genetics, paleontology, physical anthropology, and zoology.

Download or read book Population Biology and Evolution written by K. Wöhrmann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the papers presented at a symposium on popula tion biology sponsored by the Deutsche Forschungsgemeinschaft. It was . held at the guest house of the University of Ttibingen at Oberjoch on May 15-19, 1983. Prior to this conference a small group of European biologists had met in Berlin (June 1981) and Pavia (September 1982) to discuss re search problems on the borderline between population genetics and evolutionary ecology. From the contributions and discussions at these meetings it became evident that the unification of approaches to evolutionary problems in population genetics and evolutionary ecology has not yet been suc cessful and requires further efforts. It was the consensus that a larger symposium with international participation would be helpful to con front and discuss the different approaches to population biology in order to assess "where we are now" and "where we should be going. " As a result an organizational committee was formed (F. Christiansen, S. Jayakar, V. Loeschcke, W. Scharloo, and K. W6hrmann) to iden tify topics that seemed, at least to them, to be fruitful in tackling problems in population biology. Consequently, a number of colleagues were asked to participate in the meeting. We have divided this book into chapters corresponding to the eight topics chosen. The volume begins with the relation between genotype and phenotype and is followed by a chapter on quantitative genetics and selection in natural populations.

Download or read book The Pangenome written by Hervé Tettelin and published by Springer Nature. This book was released on 2020-04-30 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book offers the first comprehensive account of the pan-genome concept and its manifold implications. The realization that the genetic repertoire of a biological species always encompasses more than the genome of each individual is one of the earliest examples of big data in biology that opened biology to the unbounded. The study of genetic variation observed within a species challenges existing views and has profound consequences for our understanding of the fundamental mechanisms underpinning bacterial biology and evolution. The underlying rationale extends well beyond the initial prokaryotic focus to all kingdoms of life and evolves into similar concepts for metagenomes, phenomes and epigenomes. The book’s respective chapters address a range of topics, from the serendipitous emergence of the pan-genome concept and its impacts on the fields of microbiology, vaccinology and antimicrobial resistance, to the study of microbial communities, bioinformatic applications and mathematical models that tie in with complex systems and economic theory. Given its scope, the book will appeal to a broad readership interested in population dynamics, evolutionary biology and genomics.

Book Synopsis The Green-winged Teal by : Gaston Moisan
Download or read book The Green-winged Teal written by Gaston Moisan and published by . This book was released on 1967 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The green-winged teal is the smallest of our ducks. It is widely distributed, nesting from Alaska to Newfoundland and from the norther tree limit to central California and Maine, and wintering from British Columbia and Newfoundland south to Venezuela. As interest in waterfowl increases and the supply becomes less certain, the idea of regulating harvest by species has increased. It becomes increasingly important therefore, to learn and describe the population characteristics of each of the game species. Because of the currently low population levels of important waterfowl species such as the mallard, black duck, canvasback and redhead, regulations governing the hunting of these choice species have been restrictive. Thus species like the green-winged teal become more important as sources of additional hunting opportunity, but despite its wide distribution and rank among the 20-odd species in the harvest, information is lacking about its status. The present work reports a study of the distribution, migration, hunting kill, survival, and status of the green-winged teal in the New World.
