Download or read book Studies in Natural Products Chemistry written by Atta-ur-Rahman and published by Elsevier. This book was released on 1995-07-24 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid advances in chromatographic procedures, spectroscopic techniques and pharmacological assay methods have resulted in the discovery of an increasing number of new and interesting natural products from terrestrial and marine sources. The present volume contains comprehensive reviews on some of the major advances in this field which have taken place in recent years. The reviews include those on: novel metabolites from marine gastropods; the chemistry of marine natural products of the Halenaquinol family; secondary metabolites from Echinoderms and Bryozoans; triterpenoids and aromatic compounds from medicinal plants; chemistry and activity of sesquiterpenes from the genus Lactarius; the chemistry of bile alcohols; antifungal sesquiterpene dialdehydes; annonaceous acetogenins; nargenicin macrolides; and lignans and diarylheptanoids. Tropane alkaloids and phenolides formed by root cultures are also reviewed. Articles on natural Diels-Alder type adducts, the use of computer aided overlay for modelling the substrate binding domain of HLADH, applications of 170 NMR spectroscopy to natural product chemistry and the role of biological raw materials in synthesis are included. Volume 17 provides material of interest to natural products chemists.
Download or read book Australian Bryozoa Volume 2 written by Haylee Weaver and published by CSIRO PUBLISHING. This book was released on 2018-07-01 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bryozoans are aquatic animals that form colonies of connected individuals. They take a variety of forms: some are bushy and moss-like, some are flat and encrusting and others resemble lace. Bryozoans are mostly marine, with species found in all oceans from sublittoral to abyssal depths, but freshwater species also exist. Some bryozoans are of concern as marine-fouling organisms and invasive species, while others show promise as sources of anticancer, antiviral and antifouling substances. Written by experts in the field, Australian Bryozoa Volume 2: Taxonomy of Australian Families is the second of two volumes describing Australia’s 1200 known species of bryozoans, the richest diversity of bryozoans of any country in the world. It contains detailed taxonomic data and illustrated family-level treatments, which can be used to identify specimens. It provides an authoritative reference for biology students, academics and others interested in marine biology.
Download or read book Evolution of Sexual Reproduction in Marine Invertebrates written by Andrew (Andrey N.) Ostrovsky and published by Springer Science & Business Media. This book was released on 2013-12-16 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three major aspects that distinguish this book are that (1) it contains the most detailed analysis of the sexual reproduction (oogenesis, fertilization and embryonic incubation) in a particular phylum of the aquatic invertebrates (Bryozoa) ever made; this analysis is based on an exhaustive review of the literature on that topic published over the last 260 years, as well as extensive original histological, anatomical and morphological data obtained during studies of both extant and extinct species; (2) this broad analysis has made it possible to reconstruct the major patterns, stages and trends in the evolution of sexual reproduction in various bryozoan clades, showing numerous examples of parallelisms during transitions from broadcasting to embryonic incubation, from planktotrophic to non-feeding larvae and from lecithotrophy to placentation; corresponding shifts in oogenesis, fertilization and embryonic development are discussed in detail; and (3) the key evolutionary novelties acquired by Bryozoa are compared with similar innovations that have evolved in other groups of marine invertebrates, showing the general trends in the evolution of their sexual reproduction. Ecological background of these innovations is considered too. Altogether these aspects make the monograph an “Encyclopedia of bryozoan sexual reproduction,” offering an integral picture of the evolution of this complex phenomenon.

Download or read book Ross Sea Ecology written by F.M. Faranda and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Antarctic represents the last of the world's still unexplored continents. Since 1985, Italy has sent 10 expeditions to this region, three of those have been exclusively devoted to research on the marine ecology of the Ross Sea region. This volume presents a global picture of this research. It includes contributions on water mass characteristics, particulate organic matter and nutrient utilization, and physiological aspects of primary production. Further topics are zooplankton, krill and top predator interactions in relation to physical and biological parameters, ecological features of coastal fish communities and the spatio-temporal variability of benthic biocenoses.
Download or read book Bryozoan Studies 2010 written by Andrej Ernst and published by Springer Science & Business Media. This book was released on 2012-06-05 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bryozoa are a colonial animal phylum with a long evolutionary history, having existed from the early Ordovician (480 My) onward and still flourishing today. Several mass extinctions in earth history shaped and triggered bryozoan evolution through drastic turnover of faunas and new evolutionary lineages. Bryozoa are widespread across all latitudes from Equator to Polar Regions and occur in marine and freshwater environments. They are shaping benthic ecosystems and recording ambient environmental conditions in their skeletons. The book provides a synthesis of the current main topics of research in the field of Bryozoology including combined research on both extant, and extinct taxa. Fields or current research span molecular genetics and phylogeny, life history, reproduction and anatomy, biodiversity and evolutionary patterns in time and space, taxonomy, zoogeography, ecology, sediment interactions, and climate response.
