“…The compositions differed by reef; for instance, A. gemmifera and A. monticulosa were more abundant than A. nasuta and A. digitifera in Urasaki and Shiraho Reefs, on the east coast of Ishigaki Island (our Fig. 1a; Sugihara et al 2003). Considering that the mtCR haplotype of A. gemmifera and A. monticulosa is more similar to A. humilis than A. nasuta and A. digitifera (Wolstenholme 2004), and that the haplotype was rare in the recruits on Tomino Reef, larvae from the distant reef were unlikely to reach this study site.…”

One of the most abundant genera of scleractinian corals, Acropora, shows considerable zonation along reef slopes. The zones are thought to be established by both selective larval settlement and post-settlement selection. The latter has been credited as more important, possibly due to the obvious relationship between colony shapes and habitat-specific environmental stress. However, there is no evidence that the former has less influence on the creation of the zones. To test the hypothesis that larvae settle selectively on species-specific suitable habitat, we identified recruits using mitochondrial and nuclear molecular markers. A 2-step molecular sorting process successfully identified the 7 most dominant species in the area. Comparing the species composition of 3 different depths, the distribution of the settlement of the 3 dominant species A. digitifera, A. hyacinthus and A. tenuis was significantly related to adult zonation, suggesting that Acropora larvae selectively settle on the suitable habitat. This is the first in situ evidence showing selective settlement of coral larvae, and from it we can conclude that the initial stage of the life cycle plays an important role in establishing habitat segregation at the species level in Acropora.

“…Age control on Holocene marine terraces has been derived primarily from radiocarbon dating of associated faunal or plant material; a few studies have used optically stimulated luminescence dating (OSL; e.g., Bookhagen et al, 2006;Pfl anz et al, 2013). The largest body of work on Holocene marine terraces has been carried out in the western Pacifi c (review by Ota and Yamaguchi, 2004), in particular in Japan (e.g., Sugihara et al, 2003;Ota and Yamaguchi, 2004;Tamura et al, 2010), Taiwan (e.g., Yamaguchi and Ota, 2002;Hsieh et al, 2004), New Zealand (Wilson et al, 2006;Berryman et al, 2011), and Papua New Guinea (e.g., Chappell et al, 1998). Other sites of study include Chile (Nelson and Manley, 1992;Bookhagen et al, 2006), the Mendocino triple junction (Merritts, 1996), and Indonesia (VitaFinzi and Situmorang, 1989;Merritts et al, 1998;Briggs et al, 2008).…”

“…In other regions of the world, specifi c coral and other organisms are used as markers relative to a sea-level datum (e.g., Sugihara et al, 2003). Along the Kamchatsky Peninsula, rather than erosion or coral growth, the Holocene shoreline has a history of net sand and soil accumulation, or aggradation.…”

International audienceKamchatsky Peninsula lies within a complex meeting place of tectonic plates, in particular, the orthogonal interaction of the west-moving Komandorsky Island block with mainland Kamchatka. Examining the Holocene history of vertical deformation of marine wave-built terraces along the peninsular coast, we differentiated tectonic blocks undergoing uplift and tilting separated by zones of stable or subsided shorelines. We analyzed ∼200 excavations along >30 coastal profiles and quantified vertical deformation on single profiles as well as along the coast using paleoshorelines dated with marker tephras. For the past ∼2000 yr, the average rates of vertical deformation range from about -1 to +7 mm/yr. Uplift patterns are similar to those detected from historical leveling and from mapping of the stage 5e Quaternary marine terrace (ca. 120 ka). Average vertical deformation in the Holocene is highest for the shortest studied time period, from ca. A.D. 250 to 600, and it is several times faster than rates for marine oxygen isotope stage (MIS) 5e terraces. Vertical displacements observed along the coast are most likely coseismic and probably have included subsidence as well as uplift events. Because subsidence is generally associated with erosion, almost surely more prehistoric large earthquakes occurred than are recorded as topographic steps in these terraces. We suggest that the distribution of coastal uplift and subsidence observed along the Kamchatsky Peninsula coastline is qualitatively explained by the squeezing of the Kamchatsky Peninsula block between the Bering and Okhotsk plates, and the Komandorsky Island block

“…Discussions also addressed the regional geologic framework, the availability of biota (corals and foraminifers), diagenetic features as paleoenvironmental proxies, and critical issues related to age determination of the carbonate sequences. Coral-reef ecosystem: In the South and Central Ryukyus, corals build extensive fringing reefs dominated by a highly diverse assemblage of acroporid and poritid corals (Sugihara et al, 2003). Conversely, reefs at Tane-ga-shima, near the northern limit of coral-reef distribution, are thin, narrow, sparsely distributed, and dominated by only a few high-latitude coral species (Ikeda et al, 2006).…”
