Sea surface temperatures were warmer throughout 1998 at Sesoko Island, Japan, than in the 10 preceding years. Temperatures peaked 2.8 °C above average, resulting extensive coral bleaching and subsequent mortality. Using random quadrat surveys, we quantitatively documented community structure one year before after event. The event reduced species richness by 61% cover 85%. Colony morphology affected vulnerability Finely branched corals most susceptible, while massive encrusting colonies...
Abstract. A well-documented, publicly available, global data set of surface ocean carbon dioxide (CO2) parameters has been called for by international groups nearly two decades. The Surface Ocean CO2 Atlas (SOCAT) project was initiated the marine science community in 2007 with aim providing a comprehensive, regularly updated, CO2, which had subject to quality control (QC). Many additional data, not yet made public via Carbon Dioxide Information Analysis Center (CDIAC), were retrieved from...
Abstract. As a response to public demand for well-documented, quality controlled, publically available, global surface ocean carbon dioxide (CO2) data set, the international marine science community developed Surface Ocean CO2 Atlas (SOCAT). The first SOCAT product is collection of 6.3 million controlled from oceans and coastal seas, spanning four decades (1968–2007). gridded presented here second come project. Recognizing that some groups may have trouble working with millions measurements,...
Morphological data suggest that, unlike most other groups of marine organisms, scleractinian corals the genus Stylophora are more diverse in western Indian Ocean and Red Sea than central Indo-Pacific. However, morphology is often a poor predictor their actual biodiversity: hence, we conducted genetic survey collected Madagascar, Okinawa, Philippines New Caledonia an attempt to find out true number species these various locations.A molecular phylogenetic analysis mitochondrial ORF putative...
A comprehensive understanding of coral reproduction and development is needed because corals are threatened in many ways by human activity. Major threats include the loss their photosynthetic symbionts (Symbiodinium) caused rising temperatures (bleaching), reduced ability to calcify ocean acidification, increased storm severity associated with global climate change an increase predators runoff from agricultural In spite these threats, detailed descriptions embryonic not available for...
Endozoicomonas bacteria symbiosis with various marine organisms is hypothesized as a potential indicator of health in corals. Although many amplicon analyses using 16S rRNA gene have suggested the diversity species, genome analysis has been limited due to contamination host-derived sequences and difficulties culture metagenomic analysis. Therefore, evolutionary functional individual species symbiotic same coral remains unresolved. In this study, we applied novel single-cell genomics...
Abstract. Rising atmospheric CO2 contents have led to greater uptake by the oceans, lowering both pH due increasing hydrogen ions and CaCO3 saturation states declining carbonate ion (CO32−). Here we used previously compiled data sets new collected in 2010 2011 investigate ocean acidification of North Pacific western subarctic gyre. In winter, gyre is a source atmosphere because convective mixing deep waters rich dissolved inorganic carbon (DIC). We calculated winter mixed layer from DIC...
Historically, hermatypic corals are defined as a symbiotic system composed of an animal host, belonging to the taxa Cnidarian, and photosynthetic organism, dinoflagellate Symbiodinium spp., also known zooxanthellae. The high gross productivity stability coral reefs have been explained by efficiency coral-algal in using low nutrient concentrations found surrounding water their rapid recycling water. Although several studies reported presence bacteria closely associated with corals, mechanisms...

Most reef-building corals in tropical and subtropical areas symbiose with microalgae from the genus Symbiodinium (dinoflagellate) depend on photosynthate produced by microalgae. The majority of acquire surrounding environment through horizontal transfer, but molecular mechanisms involved acquisition remain unknown. It has been hypothesized that carbohydrate-binding proteins, or lectins, host coral recognize cell surface carbohydrates process acquiring symbionts. Thus, we examined involving...
