Carbon, nitrogen and phosphorus stoichiometry of crustacean zooplankton in the Baltic Sea
Author: J. WALVEBiology of the Baltic Sea
Author: Hans KautskyPublisher: Springer Science & Business Media
ISBN: 9401709203
Category : Science
Languages : en
Pages : 259
Book Description
The present text compiles the latest research within the field of biology performed in the Baltic Sea area. The themes span from theoretical and philosophical aspects of the ecosystem concept over population and autecological studies to detailed descriptions of plant and animal physiology. Results from microcosm and mesocosm experiments as well as direct observations in field together bring insight of the special structure and function of the Baltic Sea ecosystem. How the spawning success of cod and spat are dependent of each other and environmental factors, the impact of alien species to the composition of plankton or benthic communities, the flip of phytobenthic to planktonic communities in lagoons and mechanisms triggering the change, pure descriptions of e.g. the Estonian coast and shallow off shore areas as well as strategies for the reproductive success of Fucus vesiculosus, and the influence of eutrophication of the different Baltic Sea areas and the fate of pollutants as radionucleids and PAH etc. and other themes are all discussed in the 24 original papers of this volume.
Nitrogen in the Marine Environment

Category : Science
Languages : en
Pages : 1759
Book Description
Since the first edition of Nitrogen in the Environment published in 1983, it has been recognized as the standard in the field. In the time since the book first appeared, there has been tremendous growth in the field with unprecedented discoveries over the past decade that have fundamentally changed the view of the marine nitrogen cycle. As a result, this Second Edition contains twice the amount of information as contained in the first edition. This updated edition is now available online, offering searchability and instant, multi-user access to this important information. *The classic text, fully updated to reflect the rapid pace of discovery*Provides researchers and students in oceanography, chemistry, and marine ecology an understanding of the marine nitrogen cycle*Available online with easy access and search - the information you need, when you need it
From an Antagonistic to a Synergistic Predator Prey Perspective
Author: Tore JohannessenPublisher: Academic Press
ISBN: 0124201113
Category : Science
Languages : en
Pages : 229
Book Description
From an Antagonistic to a Synergistic Predator Prey Perspective: Bifurcations in Marine Ecosystems is a groundbreaking reference that challenges the widespread perception that predators generally have a negative impact on the abundance of their prey, and it proposes a novel paradigm — Predator-prey Synergism — in which both predator and prey enhance abundance by their co-existence. Using this model, the text explains a number of issues that appear paradoxical in the case of a negative predator-prey relationship, including observed ecosystem bifurcations (regime shifts), ecosystem resilience, red tides in apparently nutrient depleted water, and the dominance of grazed phytoplankton over non-grazed species under high grazing pressure. This novel paradigm can also be used to predict the potential impact of global warming on marine ecosystems, identify how marine ecosystem may respond to gradual environmental changes, and develop possible measures to mitigate the negative impact of increasing temperature in marine ecosystems. This book approaches the long-standing question of what generates recruitment variability in marine fishes and invertebrates in an engaging and unique way that students and researchers in marine ecosystems will understand. Introduces a new paradigm, Predator-prey Synergism, as a building block on which to construct new ecological theories. It suggests that Predator-prey Synergism is important in some terrestrial ecosystems and is in agreement with the punctuated equilibria theory of evolution (i.e., stepwise evolution). Suggests a general solution to the recruitment puzzle in marine organisms Proposes a holistic hypothesis for marine spring blooming ecosystems by considering variability enhancing and variability dampening processes Asserts that fisheries will induce variability in marine ecosystems and alter the energy flow patterns in predictable ways
Biogeochemical Transformations in the Baltic Sea
Author: Bernd SchneiderPublisher: Springer
ISBN: 3319616994
Category : Science
Languages : en
Pages : 119
Book Description
This book provides a comprehensive review of the biogeochemistry in the Baltic Sea. It is based on the fact that biogeochemical processes that are relevant for the ecological state of the Baltic Sea (and other sea areas), are all in some way related to the production and mineralization of organic matter (biomass) and thus are associated with the consumption or release of CO2. The significant progress with regard to our chemical analytical capabilities concerning the marine CO2 system has facilitated new approaches to study the Baltic Sea biogeochemistry, in particular with regard to a quantitative process understanding. To demonstrate this, the authors present the fundamentals of the marine CO2 system in a theoretically sound, but still intelligible way. This is followed by a comprehensive presentation of our current knowledge about the CO2 system in the Baltic Sea and the implications for our understanding of biogeochemical processes such as production/mineralization of organic matter and the stoichiometry involved, nitrogen fixation, denitrification, and phosphate transformations at varying redox conditions. Finally, the CO2 gas exchange balance and related problems such as acidification are addressed.

Book Description
Ecology and Management of Inland Waters: A Californian Perspective with Global Applications presents the geologic history and physical characteristics of aquatic ecology. The author draws on his research from the inland waters of California and applies this to other areas, including Mediterranean climate systems, the tropics, and even South Africa. The endorheic basins covered in this text can be found in 30% of the US, including the Aral Sea, which is a fascinating case study that provides an important warning for other locations. The author also covers Zebra Mussels, which are set to soon be a permanent population in California. The book is authored by an expert in the field who covers a very wide and interdisciplinary subject area which brings a holistic view to this complex discipline. Focuses on examples from California, which is not currently covered in most limnology books, but with an outlook to other locations Examines complex patterns of human and natural development, allowing the reader to appreciate how aquatic systems in the Anthropocene experience a new "regime" that does not rely on vague and outdated versions of ecological theory Presents a geological history, including fossil records, of California which allows the reader to appreciate how inland waters formed
