Book Description
Marine ecosystems are diverse habitats, endowed with physical, chemical, and geographical variations in the ecosystems, where the gradation from highly productive organisms to highly specialized organisms exists. India has almost 7,517 km long coast, of which 5,423 km belongs to the peninsular India, and around 2,094 km to the Andaman, Nicobar and Lakshadweep Islands. The mainland coast of India consists of 43% sandy beaches; 11% rocky coast including cliffs; and 46% mudflats or marshy coast. This massive coastline of India supports the human population tremendously through marine resources. Nearly 250 million people live within the fringe of 50 km from the coastline of India. Hence, a vital role in India’s economic growth is played by the ecological services that the marine and coastal ecosystems provide. The MPAN (Marine Protected Area Network) in India regulates the natural marine resources to conserve the depleting biodiversity for the betterment of people that are dependent on these coastal resources. Moreover, Gujarat State is bestowed with one of the longest coastline of India (1,650 km). The Gulf of Kachchh (Gujarat) is India’s first Marine National Park (MNP) contributing to the ecological importance of the state’s coastal ecosystem; exhibiting the most vulnerable biological diversity in intertidal mudflats, gulfs, bays wetlands, mangroves, salt marshes, coral reefs, beaches, dunes, and estuaries. The book Mangroves: Structure, Functions, Ecology and Biodiversity focuses on environmental and ecological studies of Gulf of Kachchh, Western Gujarat, India, in relation to eutrophication, biotic components, structure and functions of mangroves, and biomonitoring of metals. The book covers an in-depth study of surface water and bottom sediment quality, diversity, density, abundance, commonness, rarity of shells, ecological structure and functions of mangrove environment including composition, population dynamics, community structure of floral and faunal species, phytochemical constituents of selected mangrove tree species, and biomonitoring of nutrients in Avicennia marina. The book would unquestionably be the need of an hour for mangroves managers, marine conservationists, and policy makers or decision authorities to prevent the unrestrained exploitation of marine biodiversity, destruction of potential mangrove habitats, and uncontrolled interactions of man and technology with mangrove ecosystems around the world.

Book Description
Despite rapid declines in global mangrove ecosystem area, temperate mangrove ecosystems in New Zealand have increased in area in recent decades. Mangrove clearance is increasingly being used as a strategy to manage this expansion. One of the aims of mangrove clearance is to return sandflat habitats which may have been historically present. This thesis provides new insights into the impact of mangrove clearance on sediment characteristics and macrofaunal communities, best practice for mangrove clearance, and the impact of changes in mangrove ecosystem area on carbon and nitrogen stocks and fluxes. Results showed that smaller hand clearances and locations exposed to greater hydrodynamic forces showed more signs of transition to sandflat conditions (decline in mud content, change in macrofaunal communities) than larger mechanical clearances. However, sediment characteristics and macrofaunal communities remained more comparable to intact mangrove than sandflat ecosystems over 3 years following mangrove clearances. Mangrove clearance was also found to have minor impacts on sediment:water column exchange of inorganic nutrients, which was low at both intact and cleared sites. However, clearance increased the amount of CO2 released from the sediment into the atmosphere by more than 2-fold. Lower inorganic nutrient fluxes within cleared and intact mangrove compared to sandflat ecosystems was related to lower abundance of bivalves and other larger burrowing macrofauna, along with a higher fraction of silt and clay content in the surface sediment limiting nutrient exchange. This suggests that expansion of mangroves will be associated with lower sediment:water column fluxes of inorganic nutrients and a decline in the ecosystem value of this service. However, as many of the potential benefits of mangrove clearance rely on a transition to sandflat, which was not observed in this study, mangrove clearance appears unlikely to improve this ecosystem service. In addition, clearance of temperate mangrove ecosystems will likely result in a loss of ecosystem services in the form of carbon and nitrogen stocks, with temperate mangrove ecosystems found to store 117.1 ± 16.8 t C ha-1 and 15.4 ± 1.0 t N ha-1.

Book Description
This book presents a comprehensive overview and analysis of mangrove ecological processes, structure, and function at the local, biogeographic, and global scales and how these properties interact to provide key ecosystem services to society. The analysis is based on an international collaborative effort that focuses on regions and countries holding the largest mangrove resources and encompasses the major biogeographic and socio-economic settings of mangrove distribution. Given the economic and ecological importance of mangrove wetlands at the global scale, the chapters aim to integrate ecological and socio-economic perspectives on mangrove function and management using a system-level hierarchical analysis framework. The book explores the nexus between mangrove ecology and the capacity for ecosystem services, with an emphasis on thresholds, multiple stressors, and local conditions that determine this capacity. The interdisciplinary approach and illustrative study cases included in the book will provide valuable resources in data, information, and knowledge about the current status of one of the most productive coastal ecosystem in the world.

Book Description
Dynamic Sedimentary Environments of Mangrove Coasts provides knowledge on the importance of sedimentary dynamics in managing mangrove forests. In the first part of the book, the editors seamlessly offer a general introduction of mangrove sedimentary dynamics. This leads into more in-depth information on soil surface elevation change, sea level rise, and the importance of sedimentary dynamics in the loss or gain of blue carbon. The book concludes the discussion of mangrove sedimentary dynamics by addressing the issues of climate change (e.g. sea level rise and blue carbon) on mangrove restoration and sediment. This book will assist coastal managers and academics in addressing the gaps in mangrove restoration and coastal management. As such, it will be a valuable reference for advanced undergraduate students, graduate students, researchers, academics in the field of coastal restoration, and coastal management practitioners. Provides a state-of-the-art summary of research into sedimentary dynamics in mangrove forests Includes updates on issues of climate change-relevant to mangroves, such as blue carbon and sea level rise Presents scientific background and successful case studies for mangrove restoration that can solve problems relating to mangrove management

Book Description
Mangroves are basically salt tolerant forest ecosystems found mainly in tropical and sub-tropical inter-tidal regions. Till about 1960s, mangroves were largely viewed as “economically unproductive areas” and were therefore destroyed for reclaiming land for various economic and commercial activities. Gradually, with the passage of time, the economic and ecological benefits of mangroves have become visible and their importance is now well appreciated. Today, mangroves are observed in about 30 countries in tropical subtropical regions covering an area of about 99,300 Sq.Km. However, during the past 50 years, over 50% of the mangrove cover has been lost, mainly because of the increased pressure of human activities like shrimp farming and agriculture, forestry, salt extraction, urban development, tourist development and infrastructure. Also, dam on rivers, contamination of sea waters caused by heavy metals, oil spills, pesticides and other products etc. have been found to be responsible for the decline of mangroves. Although the temperature effect on growth and species diversity is not known, sea-level rise may pose a serious threat to these ecosystems The present book addresses all these important issues in separate chapters with some interesting case studies whose data may serve as pathfinder for future researches in the sphere of the influence of climate change on mangrove ecosystem. The role of mangroves in the sector of bioremediation is a unique feather in the crown of this coastal and brackishwater vegetation that may be taken up by the coastal industries in order to maintain the health of ambient environment. This book seeks to discover and to assess the vulnerability of climate change on mangrove flora and fauna, their role in carbon sequestration and some interesting case studies by some groups of dedicated researchers that may serve as the basis of future climate related policies.
