Book Description :

Sedimentary habitats cover the vast majority of the ocean floor and constitute the largest ecosystem on Earth. These systems supply fundamental services to human beings, such as food production and nutrient recycling. It is well known that meiofauna are an abundant and ubiquitous component of sediments, even though their biodiversity and importance in marine ecosystem functioning remain to be fully investigated. In this book, the meiofaunal biodiversity trends in marine habitats worldwide are documented, along with the collection of empirical evidence on their role in ecosystem services, such as the production, consumption, and decomposition of organic matter, and energy transfer to higher and lower trophic levels. Meiofaunal activities, like feeding and bioturbation, induce changes in several physico-chemical and biological properties of sediments, and might increase the resilience of the benthic ecosystem processes that are essential for the supply of ecosystem goods and services required by humans. As a key component of marine habitats, the taxonomical and functional aspects of the meiofaunal community are also used for the ecological assessment of the sediments’ quality status, providing important information on the anthropogenic impact of benthos.

Book Description :

The biological composition and richness of most of the Earth's major ecosystems are being dramatically and irreversibly transformed by anthropogenic activity. Yet, despite the vast areal extent of our oceans, the mainstay of research to-date in the biodiversity-ecosystem functioning arena has been weighted towards ecological observations and experimentation in terrestrial plant and soil systems. This book provides a framework for extending these concepts to a variety of marine systems. Marine Biodiversity and Ecosystem Functioning is the first book to address the latest advances in biodiversity-function science using marine examples. It brings together contributions from the leading scientists in the field to provide an in-depth evaluation of the science, before offering a perspective on future research directions for some of the most pressing environmental issues facing society today and in the future.

Book Description :

For years scientists viewed the deep sea as calm, quiet, and undisturbed, with marine species existing in an ecologically stable and uniform environment. Recent discoveries have completely transformed that understanding and the deep sea is recognized as a complicated and dynamic environment with a rich diversity of marine species. Carefully designed to provide practical information in an easily accessible format, Methods for the Study of Deep-Sea Sediments, Their Functioning, and Biodiversity covers how to investigate the biological components through analysis of their biodiversity. It also provides the protocols and methodological details needed to investigate some aspects of the functional biodiversity of variables commonly utilized to describe and understand the drivers of deep-sea ecosystem functioning. This volume contains detailed protocols for analyzing all benthic components from benthic viruses, prokaryotes, protozoa, foraminifera, to meio-, macro-, and megafauna. It includes step-by-step procedures, with additional notes on the crucial steps or possible difficulties arising from the analysis. Each chapter provides a brief introduction, a description of the sampling procedures and/or the sample treatment, and then the laboratory protocols, providing information on instrument setting and/or the solutions utilized. Each chapter also contains a visual scheme of the protocol for use during laboratory activities and for tracking each laboratory step. Linking information on biodiversity with the functioning of the marine ecosystems, the book covers all living components of the benthos. It provides practical information for anyone studying deep-sea habitats, their characteristics, functioning, and biodiversity.

Abstract: Trawling is a widely employed fishing method worldwide, but it can destructively damage the benthic ecosystem, non-selectively collect animals of all sizes, and lead to overfishing. To promote sustainable fishery, the Government of the Hong Kong Special Administrative Region implemented a trawling ban within Hong Kong's territorial waters on 31th December 2012. As this policy intervention can lower the impact to marine benthic habitats that were formerly brought by trawling activities, gradual recoveries of these habitats and their associated fisheries resources are to be expected. This study, aimed to test the hypothesis that the trawl-ban would lead to a recovery of the benthic molluscan community in Hong Kong waters in terms of their species richness, species composition and food web structure. Systematic trawl surveys were conducted between 2012 (pre trawl-ban) and 2014 (post trawl-ban) while temporal comparison was also made by contrasting these survey results with those reported in the available literature dated back to the 1970s. The composition of mollusc communities within Hong Kong waters shown significant changes over the decades. The mollusc community in the 1980s was once dominated by scavenger and pollution-tolerant species, but their populations notably declined in 2014. Their declines can be regarded as a sign of ecosystem recovery, despite the abundance of commercially important molluscan species remained low. This temporal trend implies that the Government's environmental policies such as measures for water quality improvement and the trawl-ban may have led to some slight improvements in the benthic ecosystem. For the surveys between2012and2014, there were obviously spatial, seasonal and temporal variations in diversity and biomass of molluscs. Generally, the diversity indices were low in 2012, increased throughthe2013 wet season tothe2014 wet season but declined again inthe2014 dry season. The results also suggested that marine pollution (e.g. eutrophication, red tides and hypoxia) possibly played a role in shaping the mollusc community in addition to the influence of the trawl-ban. Furthermore, massive blooms of species, such as the sea urchin Temnopleurus reevesi and starfish Archaster typicus, were encountered during the survey. These blooming of these species could outcompete the molluscs and other benthic species, leading to a change in community structure. Stable isotope analysis was applied to study the trophic dynamics among the six mollusc communities in Hong Kong, between wet and dry seasons, between 2012(pre-trawl-ban)and 2014(post-trawl-ban). Although the results were highly seasonally dependent, there were some positive post trawl-ban changes in terms of food web structure of the mollusc community at Southern Lantau and Po Toi areas, indicating some signs of ecosystem recovery. However, the other sites within and nearby Tolo area did not show any improvement. Therefore, the recovery is likely remained to be a slow process. A lack of clear improvement might due to continued impacts from other anthropogenic activities, including illegal trawling, eutrophication (i.e., harmful algal blooms) and suboptimal water quality. Without addressing these anthropogenic impacts, a full recovery of the benthic ecosystems and their associated fishery resources remains uncertain. Subje

Book Description :

The continuing global decline of the health of the sea, and the increasing depletion of marine resources and biodiversity, caused by human activity and climate change, have led to ever-increasing international concern. These changes in the marine environment highlight the importance of effective monitoring of the ecology of the benthos which has been shown to be a sensitive index of such alterations. Completely revised and updated to include many new methods and technologies, this Fourth Edition of Methods for the Study of Marine Benthos provides comprehensive coverage on the tools and techniques available to those working in the area. Commencing with an overview of the design and analysis of benthic surveys, the book continues with chapters covering the sedimentary environment, imaging and diving techniques, macro- and meiofauna techniques, deep sea sampling, energy flow and production. An additional new chapter provided in this edition covers phytobenthos techniques. Written by many of the world’s leading authorities in marine sampling techniques and use, and edited by Professor Anastasios Eleftheriou, this comprehensive Fourth Edition is an essential tool for all marine and environmental scientists, ecologists, fisheries workers and oceanographers. Libraries in all research establishments and universities where these subjects are studied and taught will find this book to be a hugely valuable addition to their collections.

Book Description :

Ten years ago Polar Biology published the book, Weddell Sea Ecology, containing the European "Polarstern" study EPOS in the Weddell Sea and Peninsula waters 1988/89. In certain respects, the present collection of papers, first published in Polar Biology in 2001, is a follow-up as it combines papers partly based on three "Polarstern" expeditions to the same region. Further articles relate to both land-based and shipborne studies, again primarily in the Atlantic sector and around the Antarctic Peninsula. The SCAR programme, "Ecology of the Antarctic Sea Ice Zone" (EASIZ), served as an umbrella for a truly international cooperation. Although funding came exclusively from national sources, 40% of the scientists on board "Polarstern" were foreigners. Out of the 35 papers of the present volume not less than 14 papers have multinational authorship. The scope of EASIZ is wider ilian the Southern Ocean Studies in JGOFS and GLOBEC. The Contents reflect emphasis on the study of benthos, which hitherto had not received the necessary attention in the attempt to understand key questions of evolution and zoogeography of fauna from the Southern Hemisphere. The information collected under EASIZ enhanced greatly our recognition of the rather high biodiversity of ilie Antarctic shelf benthos. In order to extend these studies to ilie deeper continental slopes and the deep sea, "Polarstern" is presently on her way for ilie first international survey of deep-sea benthos in the Atlantic sector of ilie Southern Ocean.

Book Description :

This book presents the main drivers of benthic structure and processes in estuaries from the 8,000 km-Brazilian coast, assesses the influence of natural and human disturbance, and discusses their ecological importance and management needs. Estuaries are unique coastal ecosystems often with low biodiversity that sustain and provide essential ecological services to mankind. These ecosystems include a variety of habitats with their own sediment and fauna dynamics, all of them globally altered or threatened by human activities. Mangroves, saltmarshes, tidal flats and other confined estuarine systems are under increasing stress by overfishing and other human activities leading to habitat and species loss. Combined changes in estuarine hydromorphology and in climate pose severe threats to estuarine ecosystems at a global scale.
