Book Description
Excerpt from A Study of Fresh-Water Plankton Communities: With Nine Figures Land communities develop and reach maturity by a long series of successional stages. If comparable fresh - water communities exist, they may be expected to reach maturity through a series of developmental stages. Communities of various ranks comparable to similar aggregations on land should be definitely ascertainable in fresh water. It should be possible to show a series of developmental communities ultimately reaching a permanent stable condition equivalent to that of a terrestrial climax community, as outlined by plant ecologists (clements.

Plankton Ecology
Author: Ulrich SommerPublisher: Springer Science & Business Media
ISBN: 3642748902
Category : Science
Languages : en
Pages : 378
Book Description
All relevant ecological aspects of plankton, especially seasonal changes in the species composition, the role of competition for limiting resources in species replacements, the role of parasitism, predation and competition in seasonal succession are treated in detail considering phytoplankton, zooplankton and bacteroplankton. In addition to its use as a valid reference book for plankton ecology, this monograph may well be used as a model for other kinds of ecological communities.
The Ecology of Phytoplankton
Author: C. S. ReynoldsPublisher: Cambridge University Press
ISBN: 1139454897
Category : Science
Languages : en
Pages : 437
Book Description
This important new book by Colin Reynolds covers the adaptations, physiology and population dynamics of phytoplankton communities. It provides basic information on composition, morphology and physiology of the main phyletic groups represented in marine and freshwater systems and in addition reviews recent advances in community ecology.
Competition and Coexistence
Author: Ulrich SommerPublisher: Springer Science & Business Media
ISBN: 3642561667
Category : Science
Languages : en
Pages : 232
Book Description
The question "Why are there so many species?" has puzzled ecologist for a long time. Initially, an academic question, it has gained practical interest by the recent awareness of global biodiversity loss. Species diversity in local ecosystems has always been discussed in relation to the problem of competi tive exclusion and the apparent contradiction between the competitive exclu sion principle and the overwhelming richness of species found in nature. Competition as a mechanism structuring ecological communities has never been uncontroversial. Not only its importance but even its existence have been debated. On the one extreme, some ecologists have taken competi tion for granted and have used it as an explanation by default if the distribu tion of a species was more restricted than could be explained by physiology and dispersal history. For decades, competition has been a core mechanism behind popular concepts like ecological niche, succession, limiting similarity, and character displacement, among others. For some, competition has almost become synonymous with the Darwinian "struggle for existence", although simple plausibility should tell us that organisms have to struggle against much more than competitors, e.g. predators, parasites, pathogens, and envi ronmental harshness.

Plankton
Author: Iain SuthersPublisher: CSIRO PUBLISHING
ISBN: 1486308805
Category : Science
Languages : en
Pages : 249
Book Description
Healthy waterways and oceans are essential for our increasingly urbanised world. Yet monitoring water quality in aquatic environments is a challenge, as it varies from hour to hour due to stormwater and currents. Being at the base of the aquatic food web and present in huge numbers, plankton are strongly influenced by changes in environment and provide an indication of water quality integrated over days and weeks. Plankton are the aquatic version of a canary in a coal mine. They are also vital for our existence, providing not only food for fish, seabirds, seals and sharks, but producing oxygen, cycling nutrients, processing pollutants, and removing carbon dioxide from our atmosphere. This Second Edition of Plankton is a fully updated introduction to the biology, ecology and identification of plankton and their use in monitoring water quality. It includes expanded, illustrated descriptions of all major groups of freshwater, coastal and marine phytoplankton and zooplankton and a new chapter on teaching science using plankton. Best practice methods for plankton sampling and monitoring programs are presented using case studies, along with explanations of how to analyse and interpret sampling data. Plankton is an invaluable reference for teachers and students, environmental managers, ecologists, estuary and catchment management committees, and coastal engineers.
Changing Plankton Communities: Causes, Effects and Consequences
Author: Kristian SpillingPublisher: Frontiers Media SA
ISBN: 2889630420

Languages : en
Pages : 189
Book Description
Marine ecosystems are changing at an unprecedented rate. In addition to the direct effects of e.g. warming surface temperatures, the environmental changes also cause shifts in plankton communities. Plankton makes up the base of the marine food web and plays a pivotal role in global biogeochemical cycles. Any shifts in the plankton community composition could have drastic consequences for marine ecosystem functioning. This Research Topic focuses on causes, effects and consequences of such shifts in the plankton community structure.
Plankton Communities
Author: Leonel PereiraPublisher: BoD – Books on Demand
ISBN: 1839686081
Category : Science
Languages : en
Pages : 200
Book Description
Plankton is a group of small organisms that are passively displaced by water, that is, they are dragged by marine tides and currents. Marine plankton, which includes organisms such as protozoa, microalgae, small crustaceans, and jellyfish, play an important role in maintaining the health and balance of the ocean and its complex food chains. Over three sections and eight chapters, this book provides a comprehensive overview of zooplankton and phytoplankton as well as their environmental and economic importance.
An Introduction to Phytoplanktons: Diversity and Ecology
Author: Ruma PalPublisher: Springer
ISBN: 8132218388
Category : Science
Languages : en
Pages : 175
Book Description
The book , ‘An Introduction to Phytoplanktons - Diversity and Ecology’ is very useful as it covers wide aspects of phytoplankton study including the general idea about cyanobacteria and algal kingdom. It contains different topics related to very basic idea of phytoplanktons such as, types ,taxonomic description and the key for identification etc. Together with it, very modern aspects of phytoplankton study including different methodologies needed for research students of botany, ecology, limnology and environmental biology are also included. The first chapter is very basic and informative and describes algal and phytoplankton classification, algal pigments, algal bloom and their control, algal toxins, wetlands algae, ecological significance of phytoplanktons etc. A general key for identification of common phytoplankton genera is also included for students who will be able to identify these genera based on the light microscopic characters. In Chapters 2-4, different aspects of phytoplankton research like primary productivity, community pattern analysis and their ecological parameter analysis have been discussed with detailed procedures. Statistical analysis is also discussed in detail. Chapter 5 includes case studies related to review, phytoplankton diversity and dynamics.
