Download or read book Reproductive Strategies and Developmental Patterns in Annelids written by Adriaan W.C. Dorresteijn and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fascination of the Annelida to scientists lies in the beauty of their structures and the functionality of their body plan, the tremendous adaptive radiation which has made it possible for these animals to colonize almost all marine, limnic and terrestrial biotopes. In doing so they have evolved a great variety of life forms, and their reproduction and development are correspondingly diverse, with many modes and patterns unique in the animal kingdom. In this special volume recent progress in this broad research area is presented by 26 specialists, in general through surveys or treatments of selected examples. Some of them review important annelid taxa such as the Nereididae, Syllidae, Spionidae, Cirratulidae, Clitellata, and Pogonophora; others analyse reproductive and developmental structures and phenomena in annelids, e.g. segmental organs, sex pheromones, oogenesis, mating systems, sperm types, life cycles, larval settlement, cleavage and symmetry of embryos, or discuss controversial approaches to annelid systematics. The book will be of interest to all zoologists who work with annelids as well as to embryologists and other researchers in reproductive biology.

Download or read book The Arabian Seas Biodiversity Environmental Challenges and Conservation Measures written by Laith A. Jawad and published by Springer Nature. This book was released on 2021-03-30 with total page 1377 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arabian Seas Marine Region encompasses marine areas from Djibouti to Pakistan, including the northern part of Somalia, the Red Sea, the Arabian/Persian Gulf, and parts of the Arabian Sea. Human pressures on the coastal and marine environments are evident throughout the region, and have resulted in harmful environmental effects. Oil and domestic, urban and industrial pollutants in several areas of this part of the world have caused local habitat degradation, eutrophication and algal blooms. Further, coastal landfill, dredging, and sedimentation, as well as nutrient and sediment runoff from phosphate mining, agriculture and grazing, and reduction in freshwater seepage due to groundwater extraction are all contributing to the degradation of coastal environments. This book discusses aspects not covered in other books on the region, which largely focus on marine biodiversity, and examines several environmental challenges that are often ignored, but which have a significant impact on the environment. Evaluating the status quo, it also recommends conservation measures and examines the abiotic factors that play a major main role in the environmental changes. Lastly, the book addresses the biodiversity of the area, providing a general context for the conservation and management measures discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Flies (Dipteria) have had an important role in deepening scientists'understanding of modern biology and evolution. The study of flies has figured prominently in major advances in the fields of molecular evolution, physiology, genetics, phylogenetics, and ecology over the last century. This volume, with contributions from top scientists and scholars in the field, brings together diverse aspects of research and will be essential reading for entomologists and fly researchers.
Download or read book Insect Defenses written by David L. Evans and published by SUNY Press. This book was released on 1990-01-01 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work takes a fresh, modern approach to investigate and explain the predator and prey relationships of insects and spiders, the major terrestrial fauna on earth. Devoted to broad and in-depth analysis of arthropod defenses against predators, the book's approach is both experimentally and theoretically based with major emphasis on evolution, predator strategies and tactics, and prey defensive adaptations and behaviors. The authors explain such topics as cryptic and aposematic coloration, the conflict between sexual and survival needs, web spider prey choice and evolution of prey counter defenses, predator-prey interactions and the origins of intelligence, bird predatory tactics, and caterpillar defense strategies. Also examined is the use of timing for fitness and survival, evolutionary gamesmanship in the predatory bat-moth relationship, colony defense by aper wasps, startle as a defense by moths, aggregation as a defense, chemicals as defenses, plant chemicals as defenses, and venoms as defenses. The authors illustrate each topic with numerous specific well-documented examples presented in a clear, readable style.
Download or read book Methods of Hydrobiology written by Jürgen Schwoerbel and published by Elsevier. This book was released on 2016-02-18 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods of Hydrobiology discusses the study of life of organism in water. It also discusses the science of inland waters, called limnology. The focuses of learning are animals, plants, and bacteria that live in water. The main object of the book is to review and evaluate the methods utilised to gather data on the characteristics of water dwellers. The topics of bacteriology are also covered. The fields of bacteriology that will be covered are hydrobacteriology, hydrobotany, and hydrozoology. The means of measurement and calculation applied by production biology are discussed. The text begins with a discussion of the types of water and their description. This is followed by a qualitative analysis of the phytoplankton. A separate chapter is devoted to the means for running water investigation. Another section of the book focuses on the procedures in the biological evaluation of underground water. The book will provide useful information to marine biologist, botanist, zoologist, microbiologist, students, and researches in the field of biological sciences.
