Biology and Geology of Coral Reefs

Biology 1 Vol. 2

 

Academic Press, 1973.

ISBNs 9780123955265

Colección: ScienceDirect

Resumen (en inglés): Biology and Geology of Coral Reefs, Volume II: Biology 1 discusses the major advances made in the biological aspects of coral reef problems. This book is organized into 12 chapters that cover the microbial aspects of coral reefs, the nutrition in corals, and diversity in coral reefs.
The opening chapters describe the distribution and role of coral reef microorganisms, as well as the significance of bacterioplankton as a food source for the marine fauna of coral reefs. The following chapter discusses the occurrence of algae in coral reef, their competition with corals for space, and their role in reef construction. Other chapters deal with food and feeding mechanisms of corals, the role of marine antibiotics in coral reef ecology, and some chemical compounds isolated from coral reef organisms, providing evidence for marine pharmacologic activity in coral reef areas. The book also discusses some basic problems relating to the distribution and abundance of hermatypic corals on reefs. It then examines species diversity on coral reefs, variety of reef structure, and the important role of toxic materials produced by holothurians on the general ecology and physiology of coral reefs. The last chapters describe the development, feeding, and behavior of the larval stages of several coral reef asteroids. Particular emphasis is given to the larval and post-larval stages of the crown-of-thorns starfish, Acanthaster planci. The starfish population explosions, the devastating effects on the hard coral cover of coral reefs, and causes and control of population explosions are also covered.
This volume will acquaint readers with some of the exciting developments in coral reef biology and will provide information that will enable them to assess the status of research in different fields.

ISBNs 9780123955272

Colección: ScienceDirect

Resumen (en inglés): Biology and Geology of Coral Reefs, Volume III: Biology 2 covers the major advances made in the biological aspects of coral reef problems. This book discusses the ecology, animal associates, and toxicity of coral reefs.
Composed of 11 chapters, the book initially describes the diversity of animals permanently or temporarily associated with living corals despite the formidable nematocyst batteries possessed by corals. The text goes on discussing some specializations of some shrimps and prawns permanently associated with living corals, thus, augmenting the number of biological niches available for colonization. The subsequent chapters deal with the appearance and distribution of coral reefs echinoderms and their biogeography; the role of fishes in the energetic of the coral reef system; the high incidence of toxic fishes in coral reef waters; and the origin, transmission, detection, pharmacology, and chemistry of ciguatoxin. The book also discusses natural and man-induced destruction of coral reef communities and the rate, manner, and extent of recovery of such destruction. It also describes the types of vegetation that grow on the limestone substratum provided by coral islands. Another chapter provides distributional data on the birds of the Great Barrier Reef region and the behavior and evolution of island populations of sea birds. The concluding chapters present the general biology of sea turtles and the factors that influence the number and types of organisms found on coral islands.
This book will acquaint readers with some of the exciting developments in coral reef biology and will provide information that will enable them to assess the status of research in different fields.

Biology and Management of Lobsters, The

Ecology and Management Vol. 2

 

Academic Press, 1980.

ISBNs 9780080917344

Colección: ScienceDirect

Resumen (en inglés): This two-volume work presents a summary and review of the current state of lobster biology, ecology, physiology, behavior, and management. It emphasizes the biology of clawed lobsters (Nephropidae) and spiny lobsters (Palinuridae), with attention also given to slipper lobsters (Scyllaridae) and coral lobsters (Synaxidae).
The first chapter of Volume 1 provides an overview of the general aspects of lobster biology that serves as an introduction for readers of both volumes. Subsequent chapters examine the topics of growth, neurobiology, reproduction, nutrition, pathology, social behavior, and migration patterns.
The chapters in Volume II consider the ecology, population dynamics, fishery biology, and aquaculture of spiny and clawed lobsters. The topics selected in both volumes represent areas of current research whose findings have not been previously synthesized into a coherent form.
An important feature of these volumes is the emphasis on the interaction between biology and management and culture. Many of the contributors have done research in both applied and basic biology and can articulate both points of view. The interaction between basic and applied research is of fundamental importance in these volumes in which management aspects of the research have been integrated with the basic biology of lobsters.
The Biology and Management of Lobsterswill be of interest to crustacean biologists, marine biologists and ecologists, zoologists, physiologists, animal behavior researchers, aquaculturalists, fisheries biologists and managers of fisheries, neurobiologists, pathologists, and food scientists.

Academic Press, 1989.

ISBNs 9780124848108

Colección: ScienceDirect

Resumen (en inglés): The Biology and Utilization of Shrubs brings together the wide range of information about shrubs from many disciplines and world locations. The book is organized into seven parts. Part I describes the major shrublands found on each of the vegetated continents. It provides an overview of the dominant shrubland types as well as the associated features of soil and climate that influence the geographic distribution of major shrub species. Part II discusses environmental influences and plant responses. Part III considers the range of genetic diversity for important traits and how these may vary in different habitats. Part IV discusses the effects of stress on physiological processes of shrubs, and the kinds of strategies shrubs employ to meet physiological stress. Part V offers evidence to support the claim that the many virtues of shrubs provide a basis for sustaining shrub use for livestock fodder, wildlife habitat, reclamation and erosion control, fuel, and naturalized landscaping. Part VI outlines methods for collecting and processing seeds from natural stands or from superior genotypes planted in seed production orchards.

Biology Control in Agriculture IPM System

 

Academic Press, 1985.

ISBNs 9780123570307

Colección: ScienceDirect

Resumen (en inglés): Biological Control in Agricultural IPM Systems covers the proceedings of the 1984 symposium on Biological Control in Agricultural IPM Systems, held in the Citrus Research and Education Center of the University of Florida at Lake Alfred. The symposium summarizes the status and practical use of biological control in agricultural integrated pest management (IPM) systems in the United States. The book is organized into seven parts encompassing 31 chapters that cover the biological control of arthropods, weeds, plant pathogens, and nematodes.
After briefly discussing the status and issues of biological control in IPM, the book deals with the basic principles of IPM programs and their related costs, risks, and benefits in biological control. The text also describes the compatibility of plant resistance with biological control of arthropods and the chemical mediated host or prey selection behaviors of entomophagous insects attacking herbivorous insect pests. It explains the development of microbial insecticides; the genetic improvement of insect pathogens; the use of entomogenous nematodes in cryptic and soil habitats; and the techniques for integrating the influences of natural enemies into models of crop/pest systems. The fourth part of the book focuses on the biological control of weeds. The following part considers the general concepts relating to the unique characteristics of plant diseases affecting aerial plant parts. This part also examines the biological control of soil plant pathogens in IPM systems and the use of soilborne viruses, bacteriocins, and hypovirulent strains of fungi as biological control agents. The concluding parts describe the biological control of nematodes and the status and limits to biological control in selected commodity IPM systems, such as citrus, grapes, alfalfa, cotton, and soybean.
Entomologists, plant pathologists, weed scientists, nematologists, toxicologists, and economists will find this book invaluable.
