Download or read book Marine Protists written by Susumu Ohtsuka and published by Springer. This book was released on 2015-09-28 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive book provides a unique overview of advances in the biology and ecology of marine protists. Nowadays marine protistology is a hot spot in science to disclose life phenomena using the latest techniques. Although many protistological textbooks deal with the cytology, genetics, ecology, and pathology of specific organisms, none keeps up with the quick pace of new discoveries on the diversity and dynamics of marine protists in general. The bookMarine Protists: Diversity and Dynamics gives an overview of current research on the phylogeny, cytology, genomics, biology, ecology, fisheries, applied sciences, geology and pathology of marine free-living and symbiotic protists. Poorly known but ecologically important protists such as labyrinthulids and apostome ciliates are also presented in detail. Special attention is paid to complex interactions between marine protists and other organisms including human beings. An understanding of the ecological roles of marine protists is essential for conservation of nature and human welfare. This book will be of great interest not only to scientists and students but also to a larger audience, to give a better understanding of protists’ diverse roles in marine ecosystems.

Book Synopsis The Biology and Ecology of Tintinnid Ciliates by : John R. Dolan
Download or read book The Biology and Ecology of Tintinnid Ciliates written by John R. Dolan and published by John Wiley & Sons. This book was released on 2012-09-13 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planktonic protists both produce and consume most of the primary production in the world ocean. They not only play key roles in the oceans but also represent an astounding amount of diversity: ecological morphological and genetic. However, for most taxa their ecology, morphology, phylogeny and biogeography are either poorly known or appear to be largely unrelated to one another; this hinders our understanding of their biology as well as interpretation of emerging genetic data. Tintinnid ciliates represent a singular exception. Compared to nearly all other groups of planktonic protists, there is a very substantial and relatively detailed literature (both modern and historical) on tintinnids. This volume synthesizes knowledge concerning a wide variety of topics ranging from anatomy and systematics, physiology, behavior, ecology (including ecological roles, predators, parasites, biogeography, and cysts) to fossil history. It will appeal to an audience ranging from advanced undergraduates to researchers in the fields of Oceanography, Marine Biology and Microbial Ecology.

A Companion Website provides additional online resources for instructors and students, including a summary of key concepts and terminology for each chapter, links to further resources, and flashcards to aid self-assessment.
Book Synopsis Spatial, Temporal and Behavioral Patterns of Marine Protists by : Caterina Rodríguez Giner
Download or read book Spatial, Temporal and Behavioral Patterns of Marine Protists written by Caterina Rodríguez Giner and published by . This book was released on 2019 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: The oceans are microbial-dominated ecosystems, where protists (single-celled eukaryotes) play fundamental roles performing multiple functions as primary producers, consumers, decomposers as well as trophic linkers in aquatic food webs. Due to their ecological relevance, it is important to characterize protist communities along temporal and spatial gradients to understand their biogeography and dynamics. This will allow us to infer the processes that drive the assembly of protist communities. In this dissertation, we focused in the study of natural protists communities aiming to understand their distributions and responses within different dimensions. We first focused in the temporal dimension, analyzing the dynamics of pico- and nanoeukaryotic communities, aiming to characterize the diverse strategies of their members and to determine seasonality. We identified an annual seasonal pattern in the protist community as well as in several composing taxa. Then, we addressed the spatial dimension, analyzing the changes in community composition along the water column in 13 stations distributed in the global ocean, exploring also the vertical variation in the relative metabolic activity of different taxa. Our results showed a clear vertical stratification of the community and indicated that the mesopelagic layer is the region with the highest metabolic activity. Another aim of this thesis was to explore the response of natural protists to chemical gradients. The ocean is a complex ecosystem with nutrients heterogeneously distributed along several patches, so there may be a lot of chemical gradients promoting diverse responses on marine microbes. For that purpose, we performed chemotactic experiments to identify individual responses towards different attractants within a natural protist community. The experimental results showed a preferential response towards some of the tested chemical cues, mainly bacterial exudates. Finally, since studies on microbial diversity generally use the relative abundances of phylotypes in a given sample, we explored the relationship between the latter relative abundances to cell abundances in several chosen taxa. In sum, this dissertation determines temporal and spatial patterns in protists communities as well as chemotactic preferences in different taxa, contributing to broaden our understanding of the structuring processes operating across temporal, spatial and behavioral dimensions in the protist world.
Download or read book Straminipilous Fungi written by M.W. Dick and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: Straminipilous Fungi presents a critical comparative review of the morphology and ultrastructure, morphogenesis, cytology, molecular biology and evolution of the biflagellate fungi. These organisms encompass the fungi formerly called oomycetes; taxonomically related heterotrophs studied by mycologists; plasmodiophorids and other heterotrophs. Appropriate comparisons are made with chromophyte algae, marine heterotrophs and chytridiaceous fungi. Little-known taxa which have been referred to the various orders of flagellate fungi are also listed together with citations. A new hierarchical classification is presented which is supported by systematic accounts and synoptic keys. Dichotomous keys based on habitat and habit are given to all known species of lagenidiaceous fungi, labyrinthulids and plasmodiophorids. A unique `one stop' reference resource for plant pathologists is provided by the binominal lists, including host-related lists for the downy mildews. The book, including ca 4000 references, is a major text for post-graduate and research workers, particularly freshwater and marine biologists, soil ecologists and plant pathologists.
Download or read book Soil Protists written by Stefan Geisen and published by Sudwestdeutscher Verlag Fur Hochschulschriften AG. This book was released on 2015-10-13 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protists are by far the most diverse and abundant eukaryotes in soils. Nevertheless, very little is known about individual representatives, the diversity and community composition and ecological functioning of these important organisms. For instance, soil protists are commonly lumped into a single functional unit, i.e. bacterivores. This work tackles missing knowledge gaps on soil protists and common misconceptions using multi-methodological approaches including cultivation, microcosm experiments and environmental sequencing. In a first part, several new species and genera of amoeboid protists are described showing their immense unknown diversity. In the second part, the enormous complexity of soil protists communities is highlighted using cultivation- and sequence-based approaches. In the third part, the present of diverse mycophagous and nematophagous protists are shown in functional studies on cultivated taxa and their environmental importance supported by sequence-based approaches. This work is just a start for a promising future of soil Protistology that is likely to find other important roles of these diverse organisms.
Book Synopsis Marine Protists by : Alexis Leah Pasulka
Download or read book Marine Protists written by Alexis Leah Pasulka and published by . This book was released on 2013 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heterotrophic protists are abundant and ecologically important members of marine ecosystems. They influence energy flow and biogeochemical cycling by consuming prokaryotes and remineralizing nutrients. They also serve as trophic links between microbial and metazoan food webs. To advance our understanding of microbial community structure and trophic relationships, I aim to characterize the distributions, diversity and trophic dynamics of heterotrophic protists in three different marine ecosystems using a combination of microscopy, molecular and analytical approaches. Using epifluroescence microscopy, I completed the first characterization of seasonal variability in abundance, biomass and size structure of pico- and nano-sized autotrophic and heterotrophic protists at Stn. ALOHA. This study indicates that trophic interactions of protistan grazers impact the structure of lower trophic levels over seasonal and interannual time-scales. The novel application of a method developed for simultaneous determination of rates of viral lysis and grazing mortality in the California Current Ecosystem enabled me to examine the relationships between picoplankton growth and mortality over a range of environmental conditions. The variability in mortality patterns for individual populations and inverse relationship between virus and grazer impacts highlight the complexity of predator-prey interactions in the marine environment. The use of molecular methods in a deep-sea methane seep enabled me to characterize the spatial distribution and diversity of marine protists in response to habitat heterogeneity within seep sediments and provide insights into the environmental factors that structure protistan communities on a range of spatial scales. In addition, the discovery of folliculinid ciliates living in five methane seeps along the Pacific margin is notable because this group of protists is a previously unrecognized, but potentially ecologically important component of seep ecosystems. Using a combination of molecular and analytical tools, I was able to provide the first direct evidence for the incorporation of methane-derived carbon by protists in deep-sea methane seep ecosystems. Characterizing protistan communities and their trophic interactions in response to varying environmental conditions is a key step towards understanding how this group of organisms influences microbial community structure and ecosystem function. The results from these studies highlight the importance of mortality processes, not just variations in growth, for structuring microbial communities. They also demonstrate how continued use and integration of multiple complementary approaches will enhance progress in exploring the underlying mechanisms regulating microbial community structure and trophic dynamics. Such information is critical for accurately predicting the response of microbial communities to a changing environment.

Book Synopsis The Marine Microbiome by : Lucas J. Stal
Download or read book The Marine Microbiome written by Lucas J. Stal and published by Springer. This book was released on 2016-06-03 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the state-of-the-art concerning the ‘marine microbiome’ and its uses in biotechnology. The first part discusses the diversity and ecology of marine microorganisms and viruses, including all three domains of life: Bacteria, Archaea, and Eukarya. It discusses whether marine microorganisms exist and, if so, why they might be unique. The second part presents selected marine habitats, their inhabitants and how they influence biogeochemical cycles, while the third discusses the utilization of marine microbial resources, including legal aspects, dissemination, and public awareness. The marine microbiome is the total of microorganisms and viruses in the ocean and seas and in any connected environment, including the seafloor and marine animals and plants. The diversity of microbial life remains unquantified and largely unknown, and could represent a hidden treasure for human society. Accordingly, this book is also intended to connect academics and industry, providing essential information for microbiologists from both fields.
