Available in PDF, EPUB and Kindle. Book excerpt: Deposit feeders, animals that derive nutrition from organic matter in sedimentary deposits, are dominant among the inhabitants of muds and, therefore, of the benthos of much of the ocean. In this volume the critical research problems pertaining to deposit feeders are identified and promising approaches for dealing with those problems are proposed. Interdisciplinary approaches are of utmost importance in the study of deposit feeders and their sedimentary environment, merging fields as disparate as nutritional physiology and sediment geochemistry. Among the topics presented are advances in theories of foraging and digestion, and new experimental approaches to study the potential foods, feeding behavior and physiology of animals that ingest sediment.

Available in PDF, EPUB and Kindle. Book excerpt: Oceanographic discontinuities (e. g. frontal systems, upwelling areas, ice edges) are often areas of enhanced biological productivity. Considerable research on the physics and biology of the physical boundaries defining these discontinues has been accomplished (see [I D. The interface between water and sediment is the largest physical boundary in the ocean, but has not received a proportionate degree of attention. The purpose of the Nato Advanced Research Workshop (ARW) was to focus on soft-sediment systems by identifying deficiencies in our knowledge of these systems and defining key issues in the management of coastal sedimentary habitats. Marine sediments play important roles in the marine ecosystem and the biosphere. They provide food and habitat for many marine organisms, some of which are commercially important. More importantly from a global perspective, marine sediments also provide "ecosystem goods and services" [2J. Organic matter from primary production in the water column and contaminants scavenged by particles accumulate in sediments where their fate is determined by sediment processes such as bioturbation and biogeochemical cycling. Nutrients are regenerated and contaminants degraded in sediments. Under some conditions, carbon accumulates in coastal and shelf sediments and may by removed from the carbon cycle for millions of years, having a potentially significant impact on global climate change. Sediments also protect coasts. The economic value of services provided by coastal areas has recently been estimated to be on the order of $12,568 9 10 y" [3J, far in excess of the global GNP.

This book was released on 2009-12-21 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive introduction to ocean ecology and a new way of thinking about ocean life Marine ecology is more interdisciplinary, broader in scope, and more intimately linked to human activities than ever before. Ocean Ecology provides advanced undergraduates, graduate students, and practitioners with an integrated approach to marine ecology that reflects these new scientific realities, and prepares students for the challenges of studying and managing the ocean as a complex adaptive system. This authoritative and accessible textbook advances a framework based on interactions among four major features of marine ecosystems—geomorphology, the abiotic environment, biodiversity, and biogeochemistry—and shows how life is a driver of environmental conditions and dynamics. Ocean Ecology explains the ecological processes that link organismal to ecosystem scales and that shape the major types of ocean ecosystems, historically and in today's Anthropocene world. Provides an integrated new approach to understanding and managing the ocean Shows how biological diversity is the heart of functioning ecosystems Spans genes to earth systems, surface to seafloor, and estuary to ocean gyre Links species composition, trait distribution, and other ecological structures to the functioning of ecosystems Explains how fishing, fossil fuel combustion, industrial fertilizer use, and other human impacts are transforming the Anthropocene ocean An essential textbook for students and an invaluable resource for practitioners

Download Free Chemical Ecology of Marine Microbial Communities PDF by Alyssa Marie Demko Full Book and published by . This book was released on 2021 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine sediments cover ~70% of the earth and host rich and diverse microbial communities. These microbial communities play an integral role in global nutrient cycling and the food web. They can be both a source of disease and/or an agent of mitigation through the natural products they produce, which can have cascading impacts on community structure and ecosystem function. Despite their importance, marine sediment microbes remain woefully understudied. The goal of this dissertation was to use next generation sequencing technology and newly developed bioinformatic pipelines to gain insight into these complex communities. First, I sought to reevaluate the 1% culturability paradigm by comparing sediment microbial communities using culture-dependent and culture-independent techniques. This comparative approach not only highlighted that >1% of sediment bacteria could be cultured, but also revealed the biases associated with culture-independent methods. Thirty-nine genera were identified in culture that were not detected with culture-independent methods, including some taxa that were fairly divergent from known cultured representatives. Next, I wanted to assess connections between sediment microbial communities, the sediment metabolome and sediment characteristics across varying spatial scales. To do this, microbial communities were sampled at three spatial scales, 1 m2 quadrats, 10 m transects, and sites across a 12 km2 area. Additionally, a small molecule in situ resin capture (SMIRC) method was employed to capture the metabolome present in sediments. The results from this study indicate that microbial diversity significantly increases with spatial scale and that sediment characteristics, such as grain size and nitrate concentrations, are significantly correlated with microbial communities. The SMIRC method was able to capture natural products and revealed the vast chemical landscape of marine sediments, much of which remains unexplored. Finally, I sought to evaluate how microbial communities in marine sediments vary in relation to the surrounding benthic environment by comparing fringing and back reefs of Mo'orea, French Polynesia. Even within a small area, ~1 km2, fringing and back reef sediment communities were distinct from each other. Back reefs exhibited greater richness and diversity in the microbial communities while fringing reefs had greater metabolomic richness. Supervised correlative analyses identified connections between microbes, metabolites and environmental characteristics such as nutrient concentration. Many of the taxa identified in the network analyses belong to relatively unknown lineages, providing important insight into the role these lineages may be playing in their communities. In conclusion, the results of this dissertation provide fundamental baseline information about the microbial communities and metabolites associated with marine sediments.
