Available in PDF, EPUB and Kindle. Book excerpt: The assessment of biological diversity and understanding the evolutionary history of organisms is integral to understanding life on earth. The Rhodymeniales is a well-defined red algal order for which interfamilial relationships are incompletely understood and species identification is complicated by the inability of traditional morphology-based approaches to reconcile convergent features and phenotypic plasticity. In this thesis, I used an integrative taxonomic approach combining molecular and morphological techniques to address rhodymenialean phylogenetic relationships and species diversity. I implemented multi-gene phylogenetics and site-stripping analyses to uncover reasonable support for interfamilial relationships within the Rhodymeniales for the first time. As part of that study, I established the phylogenetic assignment of some taxa (Binghamiopsis, Chamaebotrys, Minium) previously missing from molecular analyses, restored monophyly to notoriously polyphyletic genera by establishing Perbella gen. nov. and Fushitsunagia gen. nov., and described three novel Australian species of Drouetia (D. aggregata sp. nov., D. scutellata sp. nov., D. viridescens sp. nov.) after clarifying tetrasporangial development for that genus. Identification of recently collected material from Australia as the generitype of Leptofauchea facilitated a re-examination of that genus and its constituent species. Multigene phylogenetics provided support for Leptofauchea as a monophyletic genus for the first time. Additionally, inconsistencies with published accounts of some Leptofauchea species were clarified and two novel species (L.cocosana sp. nov., L. munseumica sp. nov.) assigned to that genus were recognized. A molecular-assisted alpha taxonomic approach employing the 5’ end of the mitochondrial cytochrome c oxidase subunit I (COI-5P) DNA barcode was implemented to reassess species diversity and redefine inaccurate or inadequate species concepts for rhodymenialean taxa in British Columbia. I resolved 16 species in 10 genera where 13 species in 11 genera were previously reported, uncovering underestimated diversity for the genera Botryocladia, Faucheocolax, Fryeella, Gloiocladia and Rhodymenia. The previous necessitated a taxonomic transfer (Fryeella callophyllidoides comb. nov. for Rhodymenia callophyllidoides), the resurrection of a previously synonymized species epithet (R. rhizoides) and the establishment of novel taxa (B. hawkesii sp. nov., R. bamfieldensis sp. nov.). That study also included reassessment of anatomical development for the monospecific genus Minium. Lastly, a comprehensive floristic survey of the genus Rhodymenia from Australia was performed using molecular-assisted alpha taxonomy with COI-5P and ITS sequence data as the genetic markers. Whereas five species were previously reported, I resolved 12 genetic groups. Four of those groups were attributed to previously recognized species, whereas some collections were attributed to a New Zealand species, R. novazelandica, expanding its biogeographical range. The remaining seven genetic groups were inconsistent with existing species of Rhodymenia and established as novel taxa (R. compressa sp. nov., R. contortuplicata sp. nov., R. gladiata sp. nov., R. insularis sp. nov., R. lociperonica sp. nov., R. norfolkensis sp. nov., R. womersleyi sp. nov.).

Book excerpt: This book is the fifth volume of the “Marine Algal Flora of China-Rhodophyta.” The series has seven volumes covering about 20 orders, 45 families, 173 genera, and 560 species including over 150 species firstly described from China, indicating significant importance to the knowledge of North-Western Pacific marine algal flora. The fifth volume Ahnfeltiales, Gigartinales, Sebdeniales, Nemastomatales, Plocamiales, Gracilariales, and Rhodymeniales. It provides first-hand literatures necessary to phycologists who aimed to study algal taxonomy and diversity, especially in the North Western Pacific region. Almost all species involved are illustrated in detail on morphology, inner structure, habitats, and geographical distribution, based upon herbarium specimens collected along the China coast, and a lot of elaborate pictures are attached inside. This flora will gain our understanding of current Chinese marine red algae, but much research is still necessary to reflect the whole picture of the red algal diversity along the China coast.

Book excerpt: Phylonyms is an implementation of PhyloCode, which is a set of principles, rules, and recommendations governing phylogenetic nomenclature. Nearly 300 clades - lineages of organisms - are defined by reference to hypotheses of phylogenetic history rather than by taxonomic ranks and types. This volume will document the Real World uses of PhyloCode and will govern and apply to the names of clades, while species names will still be governed by traditional codes. Key Features Provides clear regulations for implementing new guidelines for naming lineages of organisms incorporates expressly evolutionary and phylogenetic principles Works with existing codes of nomenclature Eliminates the reliance on rank-based classification in favor of phylogenetic relationships Related Titles: Rieppel, O.

Combines foundational information and nutritional context, offering a holistic approach to the relationship between sea vegetables, diet, nutrition, and health Provides comprehensive coverage of health benefits, including sea vegetables as sources of nutraceuticals and their specific applications in disease prevention, such as angiogenesis, diabetes, fungal infections, and others Includes Dictionary of Terms, Key Facts, and Summary points in each chapter to enhance comprehension Includes information on toxic varieties and safe consumption guidelines to supplement basic coverage of health benefits
Download or read book Evolutionary Biogeography of the Marine Algae of the North Atlantic written by David J. Garbary and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algal systematists, geologists and evolutionary biologists provide a synthesis of the evolutionary biogeography of red, brown, and green algae of the North Atlantic Ocean also considering their relationships with species and genera in the Arctic and Pacific Oceans as well as other subtropical and tropical seas. The history of the Atlantic Basin and its connections to other ocean basins is treated from the geological, paleontological and paleoclimatic perspective. This is contrasted with biogeographic analyses of marine animal systems and the role of plant/animal interactions in evolution. Some of the approaches include traditional systematic studies, cladistic analysis, the experimental evaluation of environment in establishing distribution limits and the application of molecular biology.

Available in PDF, EPUB and Kindle. Book excerpt: r ed Algae in Genome Age book most people reading this book have childhood memories about being enthralled at the beach with those rare and mysterious living forms we knew as seaweeds. We were fascinated at that time by their range of red hues and textures, and most of all, their exotic beauty. t o a scientist, red algae represent much more than apparent features. t heir complex forms have attracted morphologists for centuries; their intricate life cycles have brought more than one surprise to plant biologists familiar only with ferns and fowering plants; their unusual tastes have been appreciated for mill- nia, and their valuable chemical constituents have been exploited for nearly as long, most recently by biotech companies; their diversity in marine, freshwater, and t- restrial environments has offered centuries of engaging entertainment for botanists eager to arrange them in orderly classifcation systems; still, the red algae continue to teach us how many more challenges need to be overcome in order to understand their biodiversity, biological functions, and evolutionary histories.
Download or read book Origins of Algae and their Plastids written by Debashish Bhattacharya and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algae are of central importance in marine and freshwater ecosystems. Recent molecular sequence analyses show that the algae are of polyphyletic origins and that their evolution is best explained by tracing the endosymbiotic events that have resulted in the origins of their plastids. This volume provides a highly readable, thorough and up-to-date account of the major findings in algal, cyanobacterial and plastid phylogeny. All major algal groups (e.g., green, red, heterokont, dinoflagellate algae) are treated in separate chapters by leading experts on these groups.
