This book was released on 2024-09-25 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book illustrates the role of cellular oxidative stress as one of the most important physiological cornerstones in the evolution of biodiversity. The first part of the book provides the fundamentals to navigate the field and analyse the cross-talk between oxidative status homeostasis and other fundamental organismal functions, such as immunity and stress physiology. The second part of the book argues that oxidative stress underpins the astonishing diversity of adaptations to the environments and the evolution of life-history strategies, from growth to reproduction. Unravelling the (un)expected ways through which the need of regulating the organismal oxidative status has influenced the evolution of life, this book presents a novel integrative way of thinking about how a cellular mechanism has shaped the evolution of life and death.
Book Synopsis Effects of Reactive Oxygen Species on Life History Traits of Caenorhabditis Elegans by : Samson William Smith
Download or read book Effects of Reactive Oxygen Species on Life History Traits of Caenorhabditis Elegans written by Samson William Smith and published by . This book was released on 2012 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolutionary life history theory predicts that tradeoffs among fitness-related phenotypes will occur as a result of resource limitations and/or physiological constraints. Such tradeoffs are defined as the cost(s) incurred on one component of fitness (e.g., reproduction) by the increased expression of another fitness-related trait (e.g., longevity). Only recently have researchers begun to investigate the mechanistic bases of life history tradeoffs. A recent proposal is that reactive oxygen species (ROS) have a central role in shaping life history traits and tradeoffs. Research on disparate animal taxa has highlighted strong correlations between oxidative stress resistance and fitness-related life history traits, for example. Here, I use the model organism Caenorhabditis elegans to test several hypotheses concerning the effects of ROS on life history traits and the manifestation of life history tradeoffs. Additionally, I use heat stress and an alternate food source to explore the responses of life history traits to other forms of physiological stress. Relative fitness and other traits related to reproduction were found to be affected in mostly negative ways by increasing oxidative insult. Lifespan was surprisingly unaffected by oxidative stress, but was modified by temperature. In vivo ROS levels as measured by fluorescent microscopy reveal a tradeoff between antioxidant production and reproduction in this species.

Book Synopsis Oxidative Status and Life History Trade-offs in the Cooperatively Breeding Florida Scrub-Jay by : Rebecca Suzanne Heiss
Download or read book Oxidative Status and Life History Trade-offs in the Cooperatively Breeding Florida Scrub-Jay written by Rebecca Suzanne Heiss and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxidative damage has been linked to several degenerative diseases and, as such, the oxidative status of an organism has been widely used as a proxy for health state. Organisms able to resist attack by reactive oxygen species, or those with high levels of antioxidants, are typically assumed to be in better condition (i.e., better able to withstand oxidative damage to biomolecules). Little work, however, has focused on whether the oxidative status of an organism (particularly oxidative damage in free-living species) influences life history decisions. My research examined the interplay between oxidative status and life history characteristics in a free-living bird, the Florida Scrub-jay (Aphelocoma coerulescens). I addressed the following questions: 1) Does reproductive effort covary with oxidative status? 2) Does supplementation of carotenoids (potentially important antioxidants) alleviate oxidative stress during reproduction? 3) Does supplementation of carotenoids alleviate oxidative stress during development? 4) Is oxidative status predictive of survival during early developmental stages? I found: 1) The oxidative cost of reproduction was sex specific with pre-breeding oxidative damage levels negatively correlated with reproductive effort, however, only in males. Similarly, in males, post-breeding levels of oxidative damage were significantly greater than pre-breeding levels. 2) Supplementation with antioxidants did not significantly change reproductive effort, or affect post-breeding oxidative damage levels. However, there was a relationship between change in oxidative damage levels with reproductive effort and treatment group (i. e., supplemented with antioxidants or not). Interestingly, I found no correlation between two measures of oxidative damage and a third measure of oxidative state (total antioxidant capacity). We emphasize the importance of the assessment of multiple measures of oxidative status in future studies. 3) Supplementation of nestling did not significantly affect growth or oxidative damage measures. 4) Oxidative damage to proteins was significantly lower in older individuals, whereas TAC was significantly higher in older individuals; however, damage to DNA did not significantly differ across ages. Oxidized proteins increased significantly from the nestling to nutritional independence stages (2̃ months of age) and then subsequently declines as birds reached 9̃ months of age. There were no relationships between oxidized proteins and survival at these early life stages. .
Book Synopsis Animal Signaling and Function by : Duncan J. Irschick
Download or read book Animal Signaling and Function written by Duncan J. Irschick and published by John Wiley & Sons. This book was released on 2015-01-20 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The diversity of animal signals has been widely documented, and the generality of animal signals also tantalizingly suggests that there are common mechanisms that have selected for their origin. However, while much progress has been made on some fronts, we still lack a general theory about why the diversity of signaling structures exist. Our compilation will directly address this gap by focusing on an exciting new arena of sexual selection, namely using functional approaches to understand signaling. This approach is rooted in the idea that many signals are designed to transmit important functional imformation that is both important for issues of male quality (and hence male competition), and female choice. The increasing use of technology in sexual selection studies has enabled researchers to test whether signaling is either constrained by, or accurately transmits information about functional capacities. Further, in animals that fight vigorously, functional capacities such as endurance or strength may make the difference between winning and losing. This volume brings together a diverse collection of researchers who are actively investigating how function and signaling are related. These researchers use both a variety of methods and taxa to study animal signaling, and we believe that this integrative view is important to open up fresh vistas for why animal signals have evolved.

Download or read book Aging of the Genome written by Jan Vijg and published by OUP Oxford. This book was released on 2007-01-25 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aging has long since been ascribed to the gradual accumulation of DNA mutations in the genome of somatic cells. However, it is only recently that the necessary sophisticated technology has been developed to begin testing this theory and its consequences. Vijg critically reviews the concept of genomic instability as a possible universal cause of aging in the context of a new, holistic understanding of genome functioning in complex organisms resulting from recent advances in functional genomics and systems biology. It provides an up-to-date synthesis of current research, as well as a look ahead to the design of strategies to retard or reverse the deleterious effects of aging. This is particularly important in a time when we are urgently trying to unravel the genetic component of aging-related diseases. Moreover, there is a growing public recognition of the imperative of understanding more about the underlying biology of aging, driven by continuing demographic change.
Book Synopsis The Evolution of Multicellularity by : Matthew D. Herron
Download or read book The Evolution of Multicellularity written by Matthew D. Herron and published by CRC Press. This book was released on 2022-06-07 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the most important innovations in the history of life is the transition from single-celled organisms to more complex, multicellular organisms. Multicellularity has evolved repeatedly across the tree of life, resulting in the evolution of new kinds of organisms that collectively constitute a significant portion of Earth’s biodiversity and have transformed the biosphere. This volume examines the origins and subsequent evolution of multicellularity, reviewing the types of multicellular groups that exist, their evolutionary relationships, the processes that led to their evolution, and the conceptual frameworks in which their evolution is understood. This important volume is intended to serve as a jumping-off point, stimulating further research by summarizing the topics that students and researchers of the evolution of multicellularity should be familiar with, and highlighting future research directions for the field.
Book Synopsis Urban Evolutionary Biology by : Marta Szulkin
Download or read book Urban Evolutionary Biology written by Marta Szulkin and published by Oxford University Press, USA. This book was released on 2020-03-05 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban Evolutionary Biology fills an important knowledge gap on wild organismal evolution in the urban environment, whilst offering a novel exploration of the fast-growing new field of evolutionary research. The growing rate of urbanization and the maturation of urban study systems worldwide means interest in the urban environment as an agent of evolutionary change is rapidly increasing. We are presently witnessing the emergence of a new field of research in evolutionary biology. Despite its rapid global expansion, the urban environment has until now been a largely neglected study site among evolutionary biologists. With its conspicuously altered ecological dynamics, it stands in stark contrast to the natural environments traditionally used as cornerstones for evolutionary ecology research. Urbanization can offer a great range of new opportunities to test for rapid evolutionary processes as a consequence of human activity, both because of replicate contexts for hypothesis testing, but also because cities are characterized by an array of easily quantifiable environmental axes of variation and thus testable agents of selection. Thanks to a wide possible breadth of inference (in terms of taxa) that may be studied, and a great variety of analytical methods, urban evolution has the potential to stand at a fascinating multi-disciplinary crossroad, enriching the field of evolutionary biology with emergent yet incredibly potent new research themes where the urban habitat is key. Urban Evolutionary Biology is an advanced textbook suitable for graduate level students as well as professional researchers studying the genetics, evolutionary biology, and ecology of urban environments. It is also highly relevant to urban ecologists and urban wildlife practitioners.

Download or read book Ecology and Evolution of Cancer written by Beata Ujvari and published by Academic Press. This book was released on 2017-02-08 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology and Evolution of Cancer is a timely work outlining ideas that not only represent a substantial and original contribution to the fields of evolution, ecology, and cancer, but also goes beyond by connecting the interfaces of these disciplines. This work engages the expertise of a multidisciplinary research team to collate and review the latest knowledge and developments in this exciting research field. The evolutionary perspective of cancer has gained significant international recognition and interest, which is fully understandable given that somatic cellular selection and evolution are elegant explanations for carcinogenesis. Cancer is now generally accepted to be an evolutionary and ecological process with complex interactions between tumor cells and their environment sharing many similarities with organismal evolution. As a critical contribution to this field of research the book is important and relevant for the applications of evolutionary biology to understand the origin of cancers, to control neoplastic progression, and to prevent therapeutic failures. - Covers all aspects of the evolution of cancer, appealing to researchers seeking to understand its origins and effects of treatments on its progression, as well as to lecturers in evolutionary medicine - Functions as both an introduction to cancer and evolution and a review of the current research on this burgeoning, exciting field, presented by an international group of leading editors and contributors - Improves understanding of the origin and the evolution of cancer, aiding efforts to determine how this disease interferes with biotic interactions that govern ecosystems - Highlights research that intends to apply evolutionary principles to help predict emergence and metastatic progression with the aim of improving therapies
Book Synopsis Mechanisms of Life History Evolution by : Thomas Flatt
Download or read book Mechanisms of Life History Evolution written by Thomas Flatt and published by OUP Oxford. This book was released on 2011-05-12 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life history theory seeks to explain the evolution of the major features of life cycles by analyzing the ecological factors that shape age-specific schedules of growth, reproduction, and survival and by investigating the trade-offs that constrain the evolution of these traits. Although life history theory has made enormous progress in explaining the diversity of life history strategies among species, it traditionally ignores the underlying proximate mechanisms. This novel book argues that many fundamental problems in life history evolution, including the nature of trade-offs, can only be fully resolved if we begin to integrate information on developmental, physiological, and genetic mechanisms into the classical life history framework. Each chapter is written by an established or up-and-coming leader in their respective field; they not only represent the state of the art but also offer fresh perspectives for future research. The text is divided into 7 sections that cover basic concepts (Part 1), the mechanisms that affect different parts of the life cycle (growth, development, and maturation; reproduction; and aging and somatic maintenance) (Parts 2-4), life history plasticity (Part 5), life history integration and trade-offs (Part 6), and concludes with a synthesis chapter written by a prominent leader in the field and an editorial postscript (Part 7).

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.
