Download or read book Annelida written by Günter Purschke and published by Walter de Gruyter GmbH & Co KG. This book was released on 2020-02-24 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the second volume in a series of 4 volumes in the Handbook of Zoology series treating morphology, anatomy, reproduction, development, ecology, phylogeny, systematics and taxonomy of polychaetous Annelida. In this volume a comprehensive review of a few more derived higher taxa within Sedentaria are given, namely Sabellida, Opheliida/Capitellida as well as Hrabeiellidae. The former comprise annelids possessing a body divided into two more or less distinct regions or tagmata called thorax and abdomen. Here two groups of families are united, the spioniform and sabelliform polychaetes. Especially Spionidae and Sabellidae are speciose families within this group and represent two of the largest annelid families. These animals live in various types of burrows or tubes and all possess so-called feeding palps. In one group these appendages are differentiated as grooved feeding palps, whereas in the other they may form highly elaborated circular tentacular crowns comprising a number of radioles mostly giving off numerous filamentous pinnulae. Often additionally colourful, the latter are also received the common names "feather-duster worms", "flowers of the sea", "Christmas-tree worms". Opheliida/Capitellida including five families of truly worm-like annelids without appendages represents the contrary. Their members burrow in soft bottom substrates and may be classified as non-selective deposit feeders. Molecular phylogenetic analyses have shown that Echiura or spoon worms, formerly regarded to represent a separate phylum, are members of this group. Last not least Hrabeiellidae is one out of only two families of oligochaete-like terrestrial polychaetes and for this reason received strong scientific interest.

Download or read book Terrestrial Slugs written by A. South and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years slugs have become increasingly important, partly because several species are agricultural and horticultural pests and partly because theyhave proved to be useful experimental animals, particularly in the field of neurophysiology. Most of the early works which included slugs were essentially taxonomic but the book byTaylor (1902-1907) contained a great deal of biological information about slugs, some of which is still relevant today. The publication of the book by Runham and Hunter (1970) represented a milestone in slug research, providing a comprehensive survey of current knowledge about slugs. The book by Godan (1983) on snailsand slugswas mainly concerned with theeconomic importanceof theseanimals. The purpose of the present book is to present a review of current knowledgeofthebiologyandecologyofslugs, togetherwith theirstatusand control as pests. Although relatively little is known about the biology and ecology of tropical slugs and most information is taken from work on European slugs, the European pest species have become widely distributed throughout temperate regions and this book should be of interest world wide. It is written as a source of information for people seeking to control slug pests and, also, for those wishing to use slugs for research or teaching purposes. The book is intended particularly to provide a starting point for those beginning research on slugs and an extensive bibliography has been provided.
Download or read book Drosophilidae Diptera written by Irina Brake and published by BRILL. This book was released on 2013-01-21 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns about global biodiversity are rising dramatically, yet we are lagging behind in the most basic prerequisite for its understanding and conservation: the inventory. Insect species may make up five or ten times the number of all other plant and animal species combined, and as such they represent one of the major challenges in biosystematic science. World Catalogue of Insects is an initiative aiming at compiling worldscale, authoritative catalogues of monophyletic insect taxa. Volumes in this series contain standard nomenclatoral information on all names pertaining to the taxon treated, including type locality and distribution to the extent this is relevant. Additional information is optional, e.g., location, status and condition of types; biology; bibliographical information; pest status; vector status; etc. This volume nine focuses on Drosophilidae (Diptera).

Download or read book Invasive Stink Bugs and Related Species Pentatomoidea written by J.E. McPherson and published by CRC Press. This book was released on 2018-01-17 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: Key features: Presents a brief history of past classifications, a summary of present classification, and speculation on how the classification may evolve in the future Includes keys for the identification of families and subfamilies of the Pentatomoidea and for the tribes in the Pentatomidae Explains transmission of plant pathogens and concepts of pathology and heteropteran feeding for the non-specialist Provides an extensive literature review of transmission by stink bugs of viral, bacterial, fungal, and protozoan organisms that cause diseases of plants Discusses the diversity of microbial symbionts in the Pentatomidae and related species, showing how microorganisms underpin the evolution of this insect group Reviews semiochemicals (pheromones, kairomones, allomones) of the Pentatomoidea and their vital role in the life histories of pest and beneficial species and their exploitation by natural enemies of true bugs Covers past, current, and future control options for insects, with a focus on stink bugs and related heteropterans The Superfamily Pentatomoidea (stink bugs and their relatives) is comprised of 18 families with over 8,000 species, the largest of which is the family Pentatomidae (about 5,000 species). These species primarily are phytophagous, and many cause tremendous economic damage to crops worldwide. Within this superfamily are six invasive species, two that occur worldwide and four that are recent invaders in North America. Once established in new geographic regions, these species have increased their numbers and geographic distributions dramatically, causing economic damage totaling billions of dollars. Invasive Stink Bugs and Related Species (Pentatomoidea): Biology, Higher Systematics, Semiochemistry, and Management is the first book that presents comprehensive coverage of the biology of invasive pentatomoids and related true bug species and addresses issues of rapidly growing economic and environmental concerns. Containing the contributions of more than 60 stink bug specialists from 15 countries, this book provides a better understanding of the biology and economic importance of these invasive species, why they became invasive, and how their continued geographical expansion is likely to affect numerous agricultural systems and natural environments. Including over 3,500 references, this authoritative work serves as an access point to the primary literature on their life histories, higher systematics, diapause and seasonal cycles, pathogens, symbionts, semiochemistry, and pest management control strategies for pentatomoid bugs.
Download or read book Embryology of Flowering Plants Terminology and Concepts Vol 3 written by T B Batygina and published by CRC Press. This book was released on 2019-04-23 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant embryology, dealing with the regularities of initiation and the first stages of development of an organism, is now flourishing because of the overall progress being made in natural sciences. Such discoveries of the 20th century as production of plants from a single somatic cell, experimental haploidy, and parasexual hybridization were of general biological significance. The combined efforts of embryologists, geneticists and molecular biologists yielded the discovery of specific genes that control meiosis, egg cell development and early stages of embryogenesis. The tendency to synthesize data of embryology and genetics has become increasingly noticeable. It is connected with the fact that the majority of problems connected with morphogenesis, such as differentiation, specialization, the evaluation of features and the definition of the notionsgene and feature andgenotype and phenotype concern embryology and genetics (embryogenetics) in one way or another. Evolutionary embryology has given rise to a new approach to the study of problems of adaptation in plants. In connection with the problem of preserving biological diversity under conditions of ecological stress, special attention is paid to ecological embryology, revealing the critical periods in early ontogenesis and plasticity and tolerance of reproductive systems at the level of species and population. The study of variability of morphogenesis and phenotype in population (life cycle variations and the diversity of reproductive systems) is the most important point in the population embryology of plants.
