This book was released on 2020 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dendrobatid frogs have evolved a variety of unique behaviors related to parental care of tadpoles. However, few studies have investigated physiological adaptations and responses of tadpoles associated with different behaviors. The genus Ranitomeya provides a unique opportunity for comparative study as it includes two species that exhibit vastly different modes of tadpole feeding strategies: R. imitator tadpoles rely on infertile eggs provided by their parents, while R. variabilis tadpoles feed mainly on detritus. Despite these differences, tadpoles of both species can survive on alternative diets. We developed an experimental field study to compare responses to alternative feeding strategies and natural diets. To this end, we analyzed gut transcriptomes with accompanying microbiomes to investigate changes in bacterial composition and within the gut itself. Preliminary microbiome analyses revealed gut bacteria previously unknown from Ranitomeya poison frog tadpoles. Transcriptomic analyses uncovered 17 differentially expressed transcripts in R. imitator treatments, and 2,451 in R. variabilis. Critically, genes from a known group of symbiotic protists were highly expressed in egg-fed R. imitator tadpoles compared to those fed detritus. These results provide initial evidence for gut symbionts in these tadpoles, indicating the possibility that this symbiosis coevolved with egg-feeding in this species and facilitated the expansion of R. imitator into previously uninhabitable breeding pools.

Download or read book Tadpoles written by Roy W. McDiarmid and published by University of Chicago Press. This book was released on 1999-11 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: In our own juvenile stage, many of us received our wide-eyed introduction to the wonders of nature by watching the metamorphosis of swimming tadpoles into leaping frogs and toads. The recent alarming declines in amphibian populations worldwide and the suitability of amphibians for use in answering research questions in disciplines as diverse as molecular systematics, animal behavior, and evolutionary biology have focused enormous attention on tadpoles. Despite this popular and scientific interest, relatively little is known about these fascinating creatures. In this indispensable reference, leading experts on tadpole biology relate what we currently know about tadpoles and what we might learn from them in the future. Tadpoles provides detailed summaries of tadpole morphology, development, behavior, ecology, and environmental physiology; explores the evolutionary consequences of the tadpole stage; synthesizes available information on their biodiversity; and presents a standardized terminology and an exhaustive literature review of tadpole biology.

Download or read book Aquaculture Nutrition written by Daniel L. Merrifield and published by John Wiley & Sons. This book was released on 2014-10-20 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manipulation of the microbial gut content of farmed fishes and crustaceans can have a marked effect on their general health, growth, and quality. Expertly covering the science behind the use of prebiotics and probiotics this landmark book explains how the correct manipulation of the gut flora of farmed fishes and crustaceans can have a positive effect on their health, growth rates, feed utilization, and general wellbeing. Aquaculture Nutrition: Gut Health, Probiotics and Prebiotics provides a comprehensive overview of the current knowledge of the gut microbiomes of fish and their importance with respect to host-fish health and performance, providing in-depth, cutting-edge fundamental and applied information. Written by many of the world’s leading authorities and edited by Dr Daniel Merrifield and Professor Einar Ringø, this important book discusses in detail the common mechanisms for modulating microbiomes, particularly at the gut level (e.g. probiotics, prebiotics and synbiotics). The book is a key resource for an understanding of the historical development of these products, their known mechanisms of action and their degree of efficacy as presently demonstrated in the literature. The fundamental material provided on the gut microbiota itself, and more broad aspects of microbe-live feed interactions, provide essential reading for researchers, academics and students in the areas of aquaculture nutrition, fish veterinary science, microbiology, aquaculture, fish biology and fisheries. Those involved in the development and formulation of aquaculture feeds and those with broader roles within the aquaculture industry will find a huge wealth of commercially-important information within the book’s covers. All libraries in universities and research establishments where biological sciences, nutrition and aquaculture are studied and taught, should have copies of this excellent book on their shelves.

Available in PDF, EPUB and Kindle. Book excerpt: Frogs from the genus Xenopus have long been used as model organisms in basic and biomedical research. These frogs have helped unlock key fundamental developmental and cellular processes that have led to important scientific breakthroughs and have had practical application in embryology, cancer research and regenerative medicine. Xenopus Development is a vital resource on the biology and development of these key model organisms, and will be a great tool to researchers using these frogs in various disciplines of biological science. Xenopus Development is divided into four sections, the first three highlight key processes in Xenopus development from embryo to metamophosis. These sections focus on the cellular processes, organogenesis and embryo development. The final section highlights novel techniques and approaches being used in Xenopus research. Providing thorough and detailed coverage, Xenopus Development, will be a timely and welcome volume for those working in cell and molecular biology, genetics, developmental biology and biomedical research. Provides broad overview of the developmental biology of both Xenopus laevis and Xenopus tropicalis Explores cellular to systems development in key biomedical model organisms Timely synthesis of the field of Xenopus biology Highlights key biomedical and basic biological findings unlocked by Xenopus

Download or read book Ranaviruses written by Matthew J. Gray and published by Springer. This book was released on 2015-05-01 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book on ranaviruses. Ranaviruses are double-stranded DNA viruses that cause hemorrhagic disease in amphibians, reptiles, and fish. They have caused mass die-offs of ectothermic vertebrates in wild and captive populations around the globe. There is evidence that this pathogen is emerging and responsible for population declines in certain locations. Considering that amphibians and freshwater turtles are suitable hosts and the most imperiled vertebrate taxa in the world, ranaviruses can have significant impacts on biodiversity and ecosystem function. Additionally, many fish that are raised in aquaculture facilities and traded internationally are suitable hosts; thus, the potential economic impact of ranaviruses is significant. Ranaviruses also serve as a model for replication and gene function of large double-stranded DNA viruses. There is an urgent need to assemble the contemporary information on ranaviruses and provide guidance on how to assess their threats in populations. Through the Global Ranavirus Consortium, 24 experts from six countries were organize to write this volume, the first book on ranaviruses. The book begins with a discussion on the global extent of ranaviruses, case histories of infection and disease in ectothermic vertebrates, and current phylogeny. Basic principles of ranavirus ecology and evolution are covered next, with a focus on host-pathogen interactions and how the virus emerges in its environment. There are two chapters that will discuss the molecular biology of ranaviruses, host response to infection, and the genes responsible for immune system evasion. One chapter establishes standards for testing for infection and diagnosing ranaviral disease. The book ends by providing guidance on how to design ranavirus surveillance studies and analyze data to determine risk, and discussing the role of the Global Ranavirus Consortium in organizing research and outreach activities.
