“…However, the exact climatic thresholds for coral reef growth under future warming and acidified oceans are unclear (Toth et al, ), and the global extent of such high‐latitude refugia in the 21st century is largely unknown. Our study indicates that prolific coral reef growth and expansion during the mid‐Holocene Climate Optimum occurred at a time when maximum monthly summer SSTs were as much as 2.0 °C higher than at present (Wei et al, ) and sea surface pH (7.9–8.1) was low (Liu et al, ). These results imply that mid‐Holocene coral reefs in the SCS thrived in conditions that are broadly similar to that expected by the middle 21st century under future climate change (Pandolfi et al, ).…”

“…It provides moisture source for the East Asian summer monsoon (EASM) precipitation and is sensitive to numerous physical forces such as seasonal monsoon, upwelling, and migration of the Intertropical Convergence Zone, interannual El Niño–Southern Oscillation (ENSO), and their decadal‐,centennial‐ and millennial‐scale variability (Wang et al, ; Yancheva et al, ; Yu et al, ; Figure ). It is also an important region for coral reefs whereby well‐developed Holocene fringing coral reefs surround the coastlines of China and Vietnam, and an expanse of atolls and platform reefs is located in the southern region (Liu et al, ). To date, limited systematic surveys of long‐term reef growth records have been conducted in the northern SCS.…”

“…The knowledge of sediment provenances is the basis for deciphering the climatic information preserved in the clay mineral assemblage. Detrital material deposited in the northern SCS has been shown to mainly derive from the Pearl River drainage area, Taiwan, and Luzon 30 . Due to the different geological and tectonic settings prevailing in each region, clay mineral species are distinct ( Fig.…”

The East Asian summer monsoon controls the climatic regime of an extended region through temperature and precipitation changes. As the East Asian summer monsoon is primarily driven by the northern hemisphere summer insolation, such meteorological variables are expected to significantly change on the orbital timescale, influencing the composition of terrestrial sediments in terms of both mineralogy and geochemistry. Here we present clay mineralogy and major element composition of Core MD12-3432 retrieved from the northern South China Sea, and we investigate their relationship with the East Asian summer monsoon evolution over the last 400 ka. The variability of smectite/(illite + chlorite) ratio presents a predominant precession periodicity, synchronous with the northern hemisphere summer insolation changes and therefore with that of the East Asian summer monsoon. Variations in K2O/Al2O3 are characterized by eccentricity cycles, increasing during interglacials when the East Asian summer monsoon is enhanced. Based on the knowledge of sediment provenances, we suggest that these two proxies in the South China Sea are linked to the East Asian summer monsoon evolution with different mechanisms, which are (1) contemporaneous chemical weathering intensity in Luzon for smectite/(illite + chlorite) ratio and (2) river denudation intensity for K2O/Al2O3 ratio of bulk sediment.

“…Coral reefs are widely distributed in the South China Sea (Liu et al, 2009 ; Wang et al, 2014 ). Porites lutea is the dominant, typical coral species in the Luhuitou fringing reef, which is located in the south end of the Hainan province (Zhao et al, 2008 ).…”

Actinobacteria is a ubiquitous major group in coral holobiont. The diversity and spatial and temporal distribution of actinobacteria have been rarely documented. In this study, diversity of actinobacteria associated with mucus, tissue and skeleton of Porites lutea and in the surrounding seawater were examined every 3 months for 1 year on Luhuitou fringing reef. The population structures of the P. lutea-associated actinobacteria were analyzed using phylogenetic analysis of 16S rRNA gene clone libraries, which demonstrated highly diverse actinobacteria profiles in P. lutea. A total of 25 described families and 10 unnamed families were determined in the populations, and 12 genera were firstly detected in corals. The Actinobacteria diversity was significantly different between the P. lutea and the surrounding seawater. Only 10 OTUs were shared by the seawater and coral samples. Redundancy and hierarchical cluster analyses were performed to analyze the correlation between the variations of actinobacteria population within the divergent compartments of P. lutea, seasonal changes, and environmental factors. The actinobacteria communities in the same coral compartment tended to cluster together. Even so, an extremely small fraction of OTUs was common in all three P. lutea compartments. Analysis of the relationship between actinobacteria assemblages and the environmental parameters showed that several genera were closely related to specific environmental factors. This study highlights that coral-associated actinobacteria populations are highly diverse, and spatially structured within P. lutea, and they are distinct from which in the ambient seawater.
