Impact of Snorkelers on Shallow Coral Reef Communities in Palau by Evelyn I. Otto Pdf

"With the increasing numbers of visitors arriving in Palau, most of whom come to dive and snorkel on the reefs, there are concerns about the impact of the increased number of visitors on the shallow coral reef communities. Because of the importance of our coral reefs to both the people of Palau and the visitors that come to enjoy them, it is important to determine if the increased usage of these resources is negatively affecting them. In this study, we examined the effects of the high number of snorkelers on five popular snorkeling sites. The crowded snorkeling sites were compared to reference sites, which were similar in exposure to wind and currents, and benthic communities, but had little or no tourist activity. At each site, benthic and fish surveys were conducted, as well as observations of snorkelers’ behavior. Our findings demonstrate that the snorkeling sites had significantly higher rubble cover and coral fragments. In contrast to corals, fish sizes were significantly larger at the snorkeling sites compared to the reference sites."--Page 2.

Predicting Future Oceans by William Cheung,Yoshitaka Ota,Andres Cisneros-Montemayor Pdf

Predicting Future Oceans: Sustainability of Ocean and Human Systems Amidst Global Environmental Change provides a synthesis of our knowledge of the future state of the oceans. The editors undertake the challenge of integrating diverse perspectives—from oceanography to anthropology—to exhibit the changes in ecological conditions and their socioeconomic implications. Each contributing author provides a novel perspective, with the book as a whole collating scholarly understandings of future oceans and coastal communities across the world. The diverse perspectives, syntheses and state-of-the-art natural and social sciences contributions are led by past and current research fellows and principal investigators of the Nereus Program network. This includes members at 17 leading research institutes, addressing themes such as oceanography, biodiversity, fisheries, mariculture production, economics, pollution, public health and marine policy. This book is a comprehensive resource for senior undergraduate and postgraduate readers studying social and natural science, as well as practitioners working in the field of natural resources management and marine conservation. Provides a synthesis of our knowledge on the future state of the oceans Includes recommendations on how to move forwards Highlights key social aspects linked to ocean ecosystems, including health, equity and sovereignty

Challenges in Tropical Coastal Zone Management by Matthias Wolff,Sebastian C.A. Ferse,Hugh Govan Pdf

This book focuses on tropical coasts, which are highly vulnerable due to a multitude of stressors. Population growth is substantial, habitats are lost and biodiversity is reduced at an alarming rate, severely affecting many ecosystem services. This situation calls for sound coastal management and the effective engagement of all relevant stakeholders. About two decades ago the M.Sc. program ISATEC (International Studies in Aquatic Tropical Ecology) was created at Bremen University (Germany) to train young scientists for a professional engagement in the complex field of tropical coastal and resource management. This book provides a platform for those Alumni to report on their work experiences and findings in their home countries and covers all regions of the tropical belt. Part I of the book provides a short review of the state of the tropical ocean and its resources and of international attempts towards sustainable ocean management starting with the Rio Declaration on Environment and Development in 1992. Part II deals with country case studies, and part III focuses on an evaluation & synopsis of those contributions. Emerging key issues for management and conservation of the tropical coastal environments are presented and critical challenges on the path towards reaching the Sustainable Development Goals (SDGs) are discussed, as are the needs for enhancing research and capacity development.

Mesophotic Coral Ecosystems by Yossi Loya,Kimberly A. Puglise,Tom C.L. Bridge Pdf

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.

The Future of Coral Reefs Subject to Rapid Climate Change: Lessons from Natural Extreme Environments by Emma F. Camp,Verena Schoepf,Peter J. Mumby,David J. Suggett Pdf

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.
