A Student's Guide to the Seashore


Book Description

This unique, concise and beautifully-illustrated guide allows students to identify over 650 of the common, widespread animals and seaweeds of the shore. User-friendly dichotomous keys are supported by details of diagnostic features and biology of each species. Now enhanced with 32 pages of colour, this much acclaimed guide is invaluable to students of marine biology at any level. Questions such as how does the species reproduce? What is its life-cycle? How does it feed? are answered in the notes accompanying each species to give a fascinating insight into the diversity and complexity of life on the shore. The text is supported by an extensive glossary of scientific terms and a comprehensive bibliography is included to aid further study. The third edition builds on the excellent reviews of earlier editions and will continue to appeal to a wide readership, including students, teachers and naturalists.




Jellyfish Blooms: Ecological and Societal Importance


Book Description

Jellyfish', a group that includes scyphomedusae, hydromedusae, siphonophores and ctenophores, are important zooplankton predatorsthroughout the world's estuaries and oceans. These beautiful creatureshave come to public attention as featured exhibits in aquaria and innews headlines as invaders and as providers of genes used inbiomedical research. Nevertheless, jellyfish are generally consideredto be nuisances because they interfere with human activities bystinging swimmers, clogging power plant intakes and nets of fishermenand fish farms, and competing with fish and eating fish eggs andlarvae. There is concern that environmental changes such as globalwarming, eutrophication, and over-fishing may result in increasedjellyfish populations.The literature reviews and research papers in this volume explore theinteractions between jellyfish and humans. Papers cover the medicalaspects of jellyfish stings, jellyfish as human food and jellyfishfisheries, interactions of jellyfish and fish, effects ofenvironmental changes on jellyfish, effects of introduced ctenophoreson the Black Sea ecosystem, factors causing increases orconcentrations of jellyfish, and others aspects of jellyfish ecology.This is an important reference for students and professional marinebiologists, oceanographers, fishery scientists, and aquarists.

Coelenterate Biology


Book Description

Coelenterate Biology: Reviews and New Perspectives highlights research areas in which coelenterates are exceptionally useful and interesting experimental animals. It outlines the state of knowledge in coelenterate research and draws attention to some of the challenging problems that are amenable for study. Coelenterates offer valuable material for many levels of inquiry—from the population and organismic to the cellular, subcellular, and molecular levels. They are especially attractive animals for studies in developmental biology and behavior. The book begins by discussing cnidarians histology, focusing on the light and electron microscopy of cnidarian tissues. There are separate chapters on the skeletal system of cnidarians; the morphology, functions, and chemistry of nematocytes; and a few aspects of the enormous subject of cnidarian development. The subsequent chapters deal with cnidarian neurobiology, behavior, locomotion, flotation, and dispersal; experimental studies on algae-cnidarian symbioses; and coelenterate bioluminescence. The book concludes with a discussion of the systems of coordination and nervous system of ctenophores.




Phylum Ctenophora


Book Description

Dr. Sparky Pappalardo, or "Pap," is a research scientist who only wants to use molecular biology to cure cancer. Instead, her work on therapeutic viruses is sabotaged, probably by another scientist. As she investigates, she uncovers corruption, extortion and malfeasance. Her Medical University seems staffed with incompetent, apathetic and addictive creatures. Strangely, her supervisor reminds her of a tunicate salp. Follow the hilarious Pap, her beautiful pet ctenophores and her "Fabio-with-brains" boyfriend as they fight a mysterious poisoning, destruction of her laboratory and violent assaults. Learn some painless biology while Pap and her quirky friends unravel these mysteries. This is the second in the fictional "Phylum" series.




Animal Evolution


Book Description

Using modern phylogenetic reasoning based on an extensive review of morphology, including ultrastructure, and embryology, each phylum is analysed to ascertain its monophyly and hence its ancestral characters.




Plankton


Book Description

A sequence of elaborate close-up photographs of a diverse range of plankton organisms displays their phosphorescent beauty and translucent colors against contrasting black backgrounds while offering historical and scientific discussions for each depicted species. --Publisher's description.




The Evolutionary Biology of Extinct and Extant Organisms


Book Description

The Evolutionary Biology of Extinct and Extant Organisms offers a thorough and detailed narration of the journey of biological evolution and its major transitional links to the biological world, which began with paleontological exploration of extinct organisms and now carries on with reviews of phylogenomic footprint reviews of extant, living fossils. This book moves through the defining evolutionary stepping stones starting with the evolutionary changes in prokaryotic, aquatic organisms over 4 billion years ago to the emergence of the modern human species in Earth's Anthropocene. The book begins with an overview of the processes of evolutionary fitness, the epicenter of the principles of evolutionary biology. Whether through natural or experimental occurrence, evolutionary fitness has been found to be the cardinal instance of evolutionary links in an organism between its ancestral and contemporary states. The book then goes on to detail evolutionary trails and lineages of groups of organisms including mammalians, reptilians, and various fish. The final section of the book provides a look back at the evolutionary journey of "nonliving" or extinct organisms, versus the modern-day transition to "living" or extant organisms. The Evolutionary Biology of Extinct and Extant Organisms is the ideal resource for any researcher or advanced student in evolutionary studies, ranging from evolutionary biology to general life sciences. - Provides an updated compendium of evolution research history - Details the evolution trails of organisms, including mammals, reptiles, arthropods, annelids, mollusks, protozoa, and more - Offers an accessible and easy-to-read presentation of complex, in-depth evolutionary biology facts and theories
