This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Storms such as hurricanes can dramatically impact a coral reef. In November 1999, Hurricane Lenny traveled an unusual west to east path across the central Caribbean approximately 480 kilometers north of the island of Curacao. Reef damage surveys at 33 sites conducted just months after the storm documented occurrences of toppling, fragmentation, tissue damage, bleaching, and smothering due to the storm. Several factors influenced the degree of damage experienced by the reef, including the trend of the shoreline, coral growth form, colony size, and water depth. Curacao's location outside of the major hurricane belt and well south of the track of Hurricane Lenny shows that rarely disturbed reefs can incur significant damage by storm-generated waves that travel across a great distance. Pleistocene reef communities on the island preserve the same species of corals and reef zonation present on many modern reefs throughout the Caribbean. Transects conducted along the fossil reefs show that different reef paleoenvironments (reef crest vs backreef) have different relative abundances of components. These different environments also preserve corals in the position of growth to differing extents. Many large coral colonies are preserved in growth position with the presence of few or no encrusting or boring organisms. These observations suggest a very rapid burial, possibly associated with a major regression while the corals were still alive. Although storm features on modern reefs, such as toppling and fragmentation, may potentially be preserved in the Pleistocene reefs of Curacao, these features are difficult to differentiate from those that were produced by other natural day-to-day processes such as bioerosion and processes involved with a rapid regression, including large-scale movement of sands from nearshore beaches or dunes.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 61. The effects of increased atmospheric carbon dioxide and related climate change on shallow coral reefs are gaining considerable attention for scientific and economic reasons worldwide. Although increased scientific research has improved our understanding of the response of coral reefs to climate change, we still lack key information that can help guide reef management. Research and monitoring of coral reef ecosystems over the past few decades have documented two major threats related to increasing concentrations of atmospheric CO2: (1) increased sea surface temperatures and (2) increased seawater acidity (lower pH). Higher atmospheric CO2 levels have resulted in rising sea surface temperatures and proven to be an acute threat to corals and other reef-dwelling organisms. Short periods (days) of elevated sea surface temperatures by as little as 1–2°C above the normal maximum temperature has led to more frequent and more widespread episodes of coral bleaching-the expulsion of symbiotic algae. A more chronic consequence of increasing atmospheric CO2 is the lowering of pH of surface waters, which affects the rate at which corals and other reef organisms secrete and build their calcium carbonate skeletons. Average pH of the surface ocean has already decreased by an estimated 0.1 unit since preindustrial times, and will continue to decline in concert with rising atmospheric CO2. These climate-related Stressors combined with other direct anthropogenic assaults, such as overfishing and pollution, weaken reef organisms and increase their susceptibility to disease.
Download or read book The Future of Coral Reefs Subject to Rapid Climate Change Lessons from Natural Extreme Environments written by Emma F. Camp and published by Frontiers Media SA. This book was released on 2019-01-22 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examination of corals and reef-associated organisms which endure in extreme coral reef environments is challenging our understanding of the conditions that organisms can survive under. By studying individuals naturally adapted to unfavorable conditions, we begin to better understand the important traits required to survive rapid environmental and climate change. This Research Topic, comprising reviews, and original research articles, demonstrates the current state of knowledge regarding the diversity of extreme coral habitats, the species that have been studied, and the knowledge to-date on the mechanisms, traits and trade-offs that have facilitated survival.

Download or read book Mesophotic Coral Ecosystems written by Yossi Loya and published by Springer. This book was released on 2019-05-22 with total page 984 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes what is known about mesophotic coral ecosystems (MCEs) geographically and by major taxa. MCEs are characterized by light-dependent corals and associated communities typically found at depths ranging from 30-40 m. and extending to over 150 m. in tropical and subtropical ecosystems. They are populated with organisms typically associated with shallow coral reefs, such as macroalgae, corals, sponges, and fishes, as well as specialist species unique to mesophotic depths. During the past decade, there has been an increasing scientific and management interest in MCEs expressed by the exponential increase in the number of publications studying this unique environment. Despite their close proximity to well-studied shallow reefs, and the growing evidence of their importance, our scientific knowledge of MCEs is still in its early stages. The topics covered in the book include: regional variation in MCEs; similarities and differences between mesophotic and shallow reef taxa, biotic and abiotic conditions, biodiversity, ecology, geomorphology, and geology; potential connectivity between MCEs and shallow reefs; MCE disturbances, conservation, and management challenges; and new technologies, key research questions/knowledge gaps, priorities, and future directions in MCE research.
