This summary provides resorts, tourism operators, and policy makers with an introduction to marine conservation agreements (MCA) and outlines a process for planning and implementing an MCA in Fiji.
Sea surface temperature, determined remotely by satellite (SSST), measures only the thin “skin” of the ocean but is widely used to quantify the thermal regimes on coral reefs across the globe. In situ measurements of temperature complements global satellite sea surface temperature with more accurate measurements at specific locations/depths on reefs and more detailed data. In 1999, an in situ temperature-monitoring network was started in the Republic of Palau after the 1998 coral bleaching event.
The degradation of coastal habitats, particularly coral reefs, raises risks by increasing the exposure of coastal communities to flooding hazards. The protective services of these natural defenses are not assessed in the same rigorous economic terms as artificial defenses, such as seawalls, and therefore often are not considered in decision making. Here we combine engineering, ecologic, geospatial, social, and economic tools to provide a rigorous valuation of the coastal protection benefits of all U.S.
Valuation of coral reefs in Japan: Willingness to pay for conservation and the effect of information
In recent decades, despite their value, coral reefs have been endangered and are swiftly declining because of land overuse, rising sea temperatures, and increasing ocean acidification. This study assesses the willingness to pay (WTP) for coral reef conservation in Japan. We conducted an online discrete choice experiment with 10,573 respondents. A latent class logit model framework was used, and three respondent classes were recognized.
To Feed or Not to Feed? Coral Reef Fish Responses to Artificial Feeding and Stakeholder Perceptions in the Aitutaki Lagoon, Cook Islands
Feeding wild animals is a regular habit in ecotourism worldwide with poorly known consequences for ecosystem functioning. This study investigates how effective bread feeding is at attracting coral reef fish in the South Pacific, which feeding groups of fish are most attracted, and how natural foraging rates of an omnivorous and a grazingdetritivorous fish are affected. Data were collected at sites where fish are regularly fed bread by snorkellers and at comparison sites where bread was only provided for this study, within the Aitutaki lagoon (Cook Islands).
On the Global Reef Expedition—one of the largest coral reef studies in history—the Khaled bin Sultan Living Oceans Foundation conducted research in the Solomon Islands to map and characterize shallow marine habitats and assess the status of coral reef benthic and fish communities. Working in partnership with local officials and scientists from around the world, the Foundation surveyed reefs in the Western, Isabel, and Temotu Provinces from October 26 through November 24, 2014.
The world has recognized the reefs of New Caledonia as hosting some of the most beautiful and well-preserved tropical marine habitats, globally. New Caledonia is isolated in the southwest Pacific Ocean, about 1,300 km east of Australia. The country is situated in the Coral Sea, which hosts some of the most biodiverse coral reefs in the world. In July 2008, UNESCO declared the Entrecasteaux Atolls, as well as the lagoon surrounding Grande Terre, and four other marine sites, as official World Heritage Sites with the goal of preserving and protecting New Caledonia’s coral reef habitats.
Coral reefs worldwide are suffering mass mortalities from marine heat waves. With the aim of enhancing coral bleaching tolerance, we evolved 10 clonal strains of a common coral microalgal endosymbiont at elevated temperatures (31°C) for 4 years in the laboratory. All 10 heat-evolved strains had expanded their thermal tolerance in vitro following laboratory evolution. After reintroduction into coral host larvae, 3 of the 10 heat-evolved endosymbionts also increased the holobionts’ bleaching tolerance.
Scientific Consensus Statement 2013 - Chapter 2: Resilience of Great Barrier Reef marine Ecosystems and Drivers of Change
This chapter focuses on the temporal dynamics, spatial extent and cumulative impacts of current and future drivers of change on Great Barrier Reef water quality, and subsequent impacts on marine ecosystems in the Great Barrier Reef Marine Park. These include the acute influences of large flood events driven by extreme weather, salinity stress, tropical cyclones, thermal stress, crown-of-thorns starfish outbreaks and other anthropogenic drivers such as coastal development activities.
In April 2011, the Khaled bin Sultan Living Oceans Foundation (KSLOF) embarked on the Global Reef Expedition (GRE)- the largest coral reef survey and mapping expedition in history. The GRE was a rigorous five-year scientific mission to study coral reefs around the world. The expedition was designed to assess the impact of anthropogenic and natural disturbances on reef ecosystems, including runoff, climate change, storm damage, and Crown-of-Thorns Starfish (COTS) outbreaks.
