Book Description
The Great Barrier Reef Marine Park is 344 400 square kilometres in size and is home to one of the most diverse ecosystems in the world. This comprehensive guide describes the organisms and ecosystems of the Great Barrier Reef, as well as the biological, chemical and physical processes that influence them. Contemporary pressing issues such as climate change, coral bleaching, coral disease and the challenges of coral reef fisheries are also discussed. In addition,the book includes a field guide that will help people to identify the common animals and plants on the reef, then to delve into the book to learn more about the roles the biota play. Beautifully illustrated and with contributions from 33 international experts, The Great Barrier Reef is a must-read for the interested reef tourist, student, researcher and environmental manager. While it has an Australian focus, it can equally be used as a baseline text for most Indo-Pacific coral reefs. Winner of a Whitley Certificate of Commendation for 2009.

Book Description
In its third edition, this praised book demonstrates how the living systems modeling of aquatic ecosystems for ecological, biological and physiological research, and ecosystem restoration can produce answers to very complex ecological questions. Dynamic Aquaria further offers an understanding developed in 25 years of living ecosystem modeling and discusses how this knowledge has produced methods of efficiently solving many environmental problems. Public education through this methodology is the additional key to the broader ecosystem understanding necessary to allow human society to pass through the next evolutionary bottleneck of our species. Living systems modeling as a wide spectrum educational tool can provide a primary vehicle for that essential step. This third editon covers the many technological and biological developments in the eight plus years since the second edition, providing updated technological advice and describing many new example aquarium environments. - Includes 16 page color insert with 57 color plates and 25% new photographs - Offers 300 figures and 75 tables - New chapter on Biogeography - Over 50% new research in various chapters - Significant updates in chapters include: - The understanding of coral reef function especially the relationship between photosynthesis and calcification - The use of living system models to solve problems of biogeography and the geographic dispersal and interaction of species populations - The development of new techniques for global scale restoration of water and atmosphere - The development of new techniques for closed system, sustainable aquaculture

Book Description
Coral Reef Marine Plants of Hainan Island summarizes the literature on the role and use of marine plants in coral reef ecosystems, especially in China and countries in the Asia-Pacific Region. The first chapter of the book focuses on the description of coral reef ecosystems, their architecture, and status of Hainan coral reefs. The second chapter focuses on common knowledge surrounding marine plants, such as their classification, identifying characteristics of different phyla, morphology, reproduction, life forms, main algal communities on coral reefs, distribution of algae on coral reefs and their roles, and the use of seaweeds in cookery, medicine, industry, and agriculture. The third chapter on the seaweed flora of Hainan Island contains species composition of the marine benthic flora, the complete list of marine plants found by researchers from all studies, and historical changes in the flora and seasonal changes. The final chapter shows how to identify common species of marine plants on coral reefs of Hainan Island. This excellent work will help readers identify relevant plants, also teaching them how to use plant resources to assess endangered states and create conservation strategies. - Presents the first publication devoted to the description of marine plants of Hainan Island - Describes marine plants, including the role of their communities in ecosystems of coral reef - Discusses seasonal and decadal changes in biodiversity and the composition of the marine flora of the island - Combines fundamental morphology with utilization and related products

Book Description
Worldwide, coral reef communities are collapsing and shifting from coral to algal dominance. While human activities changing top-down (overfishing of grazers) and bottom-up (increases in nutrients and sediments) forces can initiate shifts, complex, non-linear interactions among stressors limit predictability (Hughes et al., 2007;Bellwood et al., 2004). Further, while top-down control is known to limit algal dominance (Knowlton & Jackson 2008; Jackson et al., 2001), less is known about bottom-up controls that may facilitate algae. One functional group of algae is turf algae, which are multi-species and often filamentous, ranging from 0.01-10cm in height (Fong & Paul 2011). Short, closely-cropped turf algae provide ecosystem functions such as primary productivity, trophic support, and nutrient cycling (Fong & Paul 2011). Under environmental stress, however, turf algae can shift to long sediment-laden turf, which may be an alternative stable state that inhibits coral recovery (Adjeroud et al., 2009). My first objective was to compare variation in the assembly of turf algae under a suite of top-down and bottom-up contexts at six sites on fringing reefs in Mo'orea French Polynesia. At each site, 10 settlement tiles were deployed and monitored for two-months and then after twelve months. During the first two months I also measured herbivore abundance, grazing pressure, sediment composition, nutrient availability, benthic community structure, and sediment deposition rates at each site. After two months turf did not vary among plots, despite significantly different herbivore abundances and nutrient availability. This implies that early successional forms are easily controlled, even by low numbers of herbivores, due to their high palatability. In contrast, after one year, tiles in highly grazed sites with low sedimentation rates were dominated by crustose coralline algae, and sites with low herbivores and high sedimentation rates dominated by long turf and macroalgae. As crustose coralline algae can facilitate coral recruitment, these results imply that herbivory can mediate the successional trajectory of algal communities toward recovery by coral or stability of the shifted algal state. A robust herbivorous fish community is the paradigm of a healthy coral reef, however, altered sediment regimes can negatively influence their grazing patterns (Tebbett et al., 2018;Bellwood & Fulton 2008), leading to algal proliferation. While increases in sediment can lead to algal proliferation through reduced grazing and release from nutrient limitation, too much sediment can lead to negative turf responses (Tebbett et al., 2018) due to the buildup of anoxic-inducing bacteria (Clausing et al., 2014). Turf are particularly prone to the influence, both positive and negative, of sediment fluxes due to their filamentous nature that trap deposited sediment (Rogers 1990). The second objective of my dissertation was to establish the non-linear relationship between sediment and turf at two sites that varied in environmental context. Before manipulations commenced I conducted field surveys of sediment depth and turf height at seven fringing reef sites around Mo'orea. I found that sediment depth and turf height varied widely among sites and although longer turf did hold more sediment that shorter turf communities, it was not disproportionally more than expected. I then choose two sites that varied the greatest in turf and sediment and deployed tiles where I manipulated sediment depth (0,1,3, & 5mm) for 25 days. Because all tiles were open to herbivory, I quantified herbivorous fish communities through visual surveys. Interestingly, I found that sediment additions have overall negative impacts on turf, and that turf between sites did have different thresholds for sediment. As turf becomes a more conspicuous component of reefs worldwide, susceptible to increases in terrestrial fluxes, understanding the dynamics of this relationship will become crucial for predicting reef recovery and resilience. In the Pacific, a healthy coral reef is characterized by intact herbivorous fish communities that reduce shifts to algal dominance through grazing (Hughes et al., 2007;Mumby et al., 2006). Sea urchins are an alternate grazing guild that are less studied, especially in the Pacific, but were found to maintain healthy algal communities on Caribbean reefs (Mumby et al., 2007;Lewis et al., 1987;Carpenter 1986; Carpenter 1985). My third objective was a novel exploration of the role urchins play in limiting algal proliferation in the South Pacific, and how this may be mediated by sediment, as sediment is known to deter fish grazing. Sediment (no addition, 3mm marine, or 3 mm terrestrial/marine mix) and presence of urchins (+/-) were manipulated in plots containing turf algae on a relatively overfished reef when compared to other Mo'orean fringing reefs (data from Mo'orea Long Term Ecological Research Project). I found urchins maintained closely cropped turf even under high sediment conditions. Further, urchins removed added sediment, likely promoting consumption by fishes. Thus, urchins can be functionally redundant grazers as they can compensate for the loss of herbivorous fishes. Overall, turf is a dynamic community, sensitive to small environmental shifts dictating abundance, proliferation, and taxonomy, potentially altering its function in coral reefs.

Book Description
Coral reefs are the largest landforms built by plants and animals. Their study therefore incorporates a wide range of disciplines. This encyclopedia approaches coral reefs from an earth science perspective, concentrating especially on modern reefs. Currently coral reefs are under high stress, most prominently from climate change with changes to water temperature, sea level and ocean acidification particularly damaging. Modern reefs have evolved through the massive environmental changes of the Quaternary with long periods of exposure during glacially lowered sea level periods and short periods of interglacial growth. The entries in this encyclopedia condense the large amount of work carried out since Charles Darwin first attempted to understand reef evolution. Leading authorities from many countries have contributed to the entries covering areas of geology, geography and ecology, providing comprehensive access to the most up-to-date research on the structure, form and processes operating on Quaternary coral reefs.
