Available in PDF, EPUB and Kindle. Book excerpt: Hong Kong provides a marginal marine environment for coral growth due to its high latitude in addition to massive freshwater run-off from the Pearl River Delta. Previous studies have reported that Hong Kong waters nurture 84 species of scleractinian corals in 28 families distributed in various locations, especially the protected bays in the eastern waters. However, very little is known about the benthic composition and health of coral communities. This study aimed to 1) determine the benthic composition of local coral communities and understand the environmental determinants of coral coverage and coral community composition; 2) record coral colony size frequency distribution across these 33 sites to understand the patterns of coral recruitment in recent years; 3) quantify coral bioerosion and corallivory by the long-spined sea urchin and explore the feasibility of remediating the coral damage by a coral-associated portunid crab. Surveys were conducted at 33 sites in Hong Kong, which cover sites with the highest coral coverages that are mainly located in the north-eastern, east and south-eastern waters. A belt-transect photo quadrant method was applied. 22 hard coral genera were identified, among which the genera Porites, Platygyra and Pavona were found to be the most abundant. Most of the study sites were dominated by few genera of massive corals which led to a low diversity. Coral coverage was negatively associated with nutrient levels including nitrogen, phosphorus and organic matter deposition rates based on sediment trap data. Apart from sedimentary parameters, coral coverage was also found to be strongly negatively correlated with the density of the long-spined sea urchin Diadema setosum. Study sites were categorized into four different conservation classes with sites of higher diversity assigned a higher conservation value. These data could serve as a baseline for measuring changes in benthic composition in the future, and as a reference for management planning such as designating new marine parks. Determining the size structure can help predict how a population may change in the future and whether conservation efforts are effective in promoting the increase in numbers of individuals. To determine coral size structure in local waters, a video transect method was adopted to capture videos on the benthic substrates of the 33 study sites. In the laboratory, the video clips were analyzed to extract information on the size and growth form of all coral colonies along the transects. Size-frequency distribution plots generally showed a highly positive skewness, which indicated a dominance of small-sized (i.e. 10 - 30 cm) colonies, yet low in recruitment-sized (i.e. 5 cm) colonies. An examination of the size distribution of the most common genera showed that the distribution patterns were more genus-dependent rather than site-dependent. Also, massive corals were the most dominant growth form, while branching corals were the least common which was different from healthy tropical reefs. Apart from establishing a baseline of coral communities, coral bioerosion was further studied. Previous studies found that coral coverage and urchin density were negatively correlated in local waters. Further, severe coral bioerosion had been reported to cause community-level coral damage in several locations. Therefore, impact coral bioerosion by the sea urchin Diadema setosum and whether such impact could be remediated were further investigated in a series of controlled experiments in the field. Although sea urchins were reported to prevent shifting from coral-dominant to algae-dominate phase elsewhere, they were found to cause severe tissue loss and bioerosion at high densities in my study. Thalamita prymna, a common portunid crab in local coral communities, was found to effectively reduce coral damages including bioerosion and surface mortality. Crab predation, an overlooked relationship in coral reefs, can thus be exploited to control urchin corallivory and bioerosion. Prohibiting fish trapping in reef areas could reduce the by-catch of these crabs and protect reefs against urchin attack.

Download or read book The Marine Flora and Fauna of Hong Kong and Southern China V written by Brian Morton and published by Hong Kong University Press. This book was released on 2000-12-01 with total page 697 pages. Available in PDF, EPUB and Kindle. Book excerpt: From 6-25 April 1998, the Tenth International Workshop on the Marine Flora and Fauna of Hong Kong and South China was convened at the Swire Institute of Marine Science of the University of Hong Kong. Thirteen scientists from six countries and twenty-two scientists and students from Hong Kong investigated aspects of the marine flora and fauna of the Cape d'Aguilar Marine Reserve and the southeastern waters of Hong Kong. This was to obtain more information about the newly-established reserve (the only one in Hong Kong) and the changes that had taken place on the seabed in the southern waters since they were dredged between 1992-1995, respectively, and, in the latter case, to see if there had been any subsequent benthic recovery. The Proceedings of the workshop contains thirty-six original research papers dealing with aspects of the taxonomy and anatomy, behaviour and physiology of marine life in Hong Kong and Southern China. Papers also explore aspects of Hong Kong's marine parks and reserves, including the pollution of Hong Kong's marine life with particular reference to the Cape d'Aguilar Marine Reserve, established only in 1996, and the fauna of its territorial southern waters. The Workshop was sponsored by the University of Hong Kong, the Croucher Foundation and the K.C. Wong Foundation so as to bring eminent overseas scientists to Hong Kong to work with their local colleagues and students. The success of the workshop concept is self-evident in the contents and scope of these proceedings. This was the eighth workshop convened in Hong Kong since 1977 and these proceedings have become the single-most important body of information on the long-term changes that have taken place in its marine environment over an extended time-frame. The volumes are also the largest regional repository of information on the marine life of the territorial waters of Hong Kong and the northern rim of the South China Sea. For those with any interest in Hong Kong's marine environment, therefore, this proceedings and its predecessors are essential reading.
Download or read book The Marine Biology of the South China Sea III written by Brian Morton and published by Hong Kong University Press. This book was released on 1998-07-01 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first conference on the Marine Biology of the South China Sea was convened in Hong Kong in 1990, to celebrate the opening of the Swire Institute of Marine Science. The second was convened in Guangzhou, China, in 1993. The third conference returned toHong Kong in 1996 and, in a continuing pattern of growth, was attended by 127 scientists and students from 14 countries and territories. Of the 1O4 keynote addresses, papers and posters presented at the meeting, 42 are published here, following critical peer review, under the symposium categories of Taxonomy and Biological Diversity, Biology and Ecology and Coastal Zone Management and Conservation of the Biological Resources, of the South China Sea.Each conference sets its own symposia themes but in view of the rapid, perceived, decline in the marine environment of the South China Sea and the overexploitation of its resources, the 1996 meeting focused its attention on these issues.There are many meetings related to marine science convened by the countries of the South China rim. Some are national, others are international, but most are typically convened by agencies and attendance is restricted to an invited few, usually senior scientists. Europe hosts a European Marine Biology Symposium, that is convened in a different country each year and which sets the meeting's themes. The proceedings of those meetings constitute one of the most authoritative accounts of the marine biology of European waters. The meeting itself provides a forum for scientists and students, so that international collaborative research is now a key feature of European marine science. First convened in 1996, the 32 symposia are a tribute to international co-operation in research in a marine environment that, of itself, knows no boundaries.The South China Sea countries also need such a forum, free of political dogma. This conference proceedings is the third to help promote such an event, hopefully, one day, at a greater frequency than three years. The fourth conference is to be convened in the Philippines in 1999.This volume then is an international perspective on the South China Sea by scientists who research it and are concerned for its future. It contains information that should appeal to marine biologists throughout the world and, in particular, to those in Asia.

Download or read book Coral Reefs Tourism Conservation and Management written by Bruce Prideaux and published by Routledge. This book was released on 2018-08-30 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coral reefs are an important tourism resource for many coastal and island destinations and generate a range of benefits to their local communities, including as a food source, income from tourism, employment and recreational opportunities. However, coral reefs are under increasing threat from climate change and related impacts such as coral bleaching and ocean acidification. Other anthropogenic stresses include over-fishing, anchor damage, coastal development, agricultural run-off, sedimentation and coral mining. This book adopts a multidisciplinary approach to review these issues as they relate to the sustainable management of coral reef tourism destinations. It incorporates coral reef science, management, conservation and tourism perspectives and takes a global perspective of coral reef tourism issues covering many of the world’s most significant coral reef destinations. These include the Great Barrier Reef and Ningaloo Reef in Australia, the Red Sea, Pacific Islands, South East Asia, the Maldives, the Caribbean islands, Florida Keys and Brazil. Specific issues addressed include climate change, pollution threats, fishing, island tourism, scuba diving, marine wildlife, governance, sustainability, conservation and community resilience. The book also issues a call for more thoughtful development of coral reef experiences where the ecological needs of coral reefs are placed ahead of the economic desires of the tourism industry.
Download or read book Conservation Palaeobiology of Marine Ecosystems written by R. Nawrot and published by Geological Society of London Special Publications. This book was released on 2023-07-03 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation palaeobiology tracks the history of ecosystems based on the fossil record to guide conservation decisions and contribute to the theoretical foundations of conservation biology. The accelerating pace of global change requires better understanding of the long-term resilience and adaptive capacities of ecosystems. Fossil assemblages in outcrops and cores, together with surface accumulations of skeletal remains, represent unique archives of past ecosystem dynamics and baseline community states prior to anthropogenic impacts. However, as biological data retrieved from fossil and death assemblages cannot be treated in isolation, conservation palaeobiology integrates palaeontological and geological tools to account for the nature of the stratigraphic record. This volume brings together studies that demonstrate how combining marine palaeoecological records with other types of geohistorical data (taphonomic, sedimentological, geochronological, geochemical) can inform biodiversity conservation and ecosystem management. The papers highlight novel approaches and challenges in applying geohistorical data to conservation problems, discuss the limitations imposed by time averaging, and offer both deep- and near-time perspectives on conservation palaeobiology of marine ecosystems.
