Part II focuses on the multitude of biotic interactions in seaweed communities, and in Part III the reader is introduced to the structure and function of the main seaweed systems of the world. The chapters of Part IV highlight and discuss the effects of global and local environmental changes on seaweeds and their communities. In the final Part V a comprehensive overview of developments in seaweed aquaculture, industrial applications and the overall economic importance of seaweeds is provided. Summarizing the advances in seaweed biology achieved within the last few decades, this book also identifies gaps in the present knowledge and needs for future research.
Download or read book The Bah a Blanca Estuary written by Sandra M. Fiori and published by Springer Nature. This book was released on 2021-08-03 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bahía Blanca Estuary is one of the largest coastal systems in Atlantic South America. This mesotidal estuary, situated in a sharp transition between humid subtropical and semiarid climates, has a unique combination of large interannual climatic variations. The estuarine area encompasses roughly 2300 square kilometers and is composed of wide expanses of intertidal flats, salt marshes, and emerged islands, which create intricate landscape patterns. Natural environments in the estuary sustain a high concentration of marine and terrestrial species, including endemic, threatened, and endangered fish and shorebirds. Puerto Cuatreros, in the inner zone of the estuary, hosts a permanent marine research station, whose records span more than 30 years of biophysical variables, and represent one of the largest time series of ecological data in South America. Beyond its ecological relevance, the Bahía Blanca Estuary is under increasing anthropogenic pressure from large urban settlements, industrial developments and harbors, raising the question of how to balance conservation and development. The Bahía Blanca Estuary: Ecology and Biodiversity offers a comprehensive review of life in the ecosystems of the estuary. The book is divided into five major sections, the first of which provides a description of the regional setting and covers key aspects of estuarine dynamics. The three following sections are dedicated to different habitat types and, within each section, the chapters are organized around major functional groups from pelagic and benthic environments. The fifth and final section covers issues related to management and conservation. Overall, the book provides essential and up-to-date reference material on the biodiversity and ecosystem processes of the Bahía Blanca Estuary, and will appeal to a broad international audience.

Download or read book POLAR NIGHT Marine Ecology written by Jørgen Berge and published by Springer Nature. This book was released on 2020-04-08 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently, the prevailing view of marine life at high latitudes has been that organisms enter a general resting state during the dark Polar Night and that the system only awakens with the return of the sun. Recent research, however, with coordinated, multidisciplinary field campaigns based on the high Arctic Archipelago of Svalbard, have provided a radical new perspective. Instead of a system in dormancy, a new perspective of a system in full operation and with high levels of activity across all major phyla is emerging. Examples of such activities and processes include: Active marine organisms at sea surface, water column and the sea-floor. At surface we find active foraging in seabirds and fish, in the water column we find a high biodiversity and activity of zooplankton and larvae such as active light induced synchronized diurnal vertical migration, and at seafloor there is a high biodiversity in benthic animals and macroalgae. The Polar Night is a period for reproduction in many benthic and pelagic taxa, mass occurrence of ghost shrimps (Caprellides), high abundance of Ctenophores, physiological evidence of micro- and macroalgal cells that are ready to utilize the first rays of light when they appear, deep water fishes found at water surface in the Polar night, and continuous growth of bivalves throughout the winter. These findings not only begin to shape a new paradigm for marine winter ecology in the high Arctic, but also provide conclusive evidence for a top-down controlled system in which primary production levels are close to zero. In an era of environmental change that is accelerated at high latitudes, we believe that this new insight is likely to strongly impact how the scientific community views the high latitude marine ecosystem. Despite the overwhelming darkness, the main environmental variable affecting marine organisms in the Polar Night is in fact light. The light regime during the Polar Night is unique with respect to light intensity, spectral composition of light and photoperiod.

Download or read book Marine Biology a Very Short Introduction written by Philip Mladenov and published by Oxford University Press, USA. This book was released on 2020-02-27 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The oceans are our planet's most distinctive and imposing natural habitat. They cover 71 percent of its surface; support a remarkably diverse and exquisitely adapted array of life forms, from microscopic viruses, bacteria, and plankton to the largest existing animals; and possess many of Earth's most significant, intriguing, and inaccessible ecosystems. In an era in which humans are significantly altering the global environment, the oceans are undergoing rapid and profound changes. The study of marine biology is thus taking on added importance and urgency as people struggle to understand and manage these changes to protect our marine ecosystems. Healthy oceans produce half of the oxygen we breathe; stabilize our climate; create ecosystems that protect our coasts from storms; provide us with abundant food; and host diverse organisms that provide us with natural products for medicine and biotechnology. In this Very Short Introduction, marine biologist Philip Mladenov provides an accessible and up-to-date overview of marine biology, offering a tour of marine life and marine processes that ranges from the unimaginably abundant microscopic organisms that drive the oceans' food web to the apex predators that we exploit for food; from polar ocean ecosystems to tropical coral reefs; and from the luxurious kelp beds of the coastal ocean to deep-ocean hydrothermal vents where life exists without the energy of the sun. Throughout the book he considers the human impacts on marine life including overfishing, plastic and nutrient pollution, the spread of exotic species, and ocean warming and acidification. He discusses the threats these pose to our welfare, and the actions required to put us on a path to a more sustainable relationship with our oceans so that they can be restored and protected for future generations. Mladenov concludes with a new chapter offering an inspiring vision for the future of our oceans in 2050 that can be realised if we are wise enough to accelerate actions already underway and be bold with implementing new approaches. The next decade will decide the state of the oceans that we leave behind for future generations. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly.

Download or read book Antarctic Seaweeds written by Iván Gómez and published by Springer Nature. This book was released on 2020-04-29 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seaweeds (macroalgae) represent the most striking living components in the Antarctic’s near-shore ecosystems, especially across the West Antarctic Peninsula and adjacent islands. Due to their abundance, their central roles as primary producers and foundation organisms, and as sources of diverse metabolically active products, seaweed assemblages are fundamental to biogeochemical cycles in Antarctic coastal systems. In recent years, the imminence of climate change and the direct impacts of human beings, which are affecting vast regions of the Antarctic, have highlighted the importance of seaweed processes in connection with biodiversity, adaptation and interactions in the benthic network. Various research groups have been actively involved in the investigation of these topics. Many of these research efforts have a long tradition, while some “newcomers” have also recently contributed important new approaches to the study of these organisms, benefiting polar science as a whole. This book provides an overview of recent advances and insights gleaned over the past several years. Focusing on a timely topic and extremely valuable resource, it assesses the challenges and outlines future directions in the study of Antarctic seaweeds.
