Life History and Stable Regeneration of the Endangered Saltmarsh
Plankton Benthos Res 9(2): 114–121, 2014 Plankton & Benthos Research © The Japanese Association of Benthology Life history and stable regeneration of the endangered saltmarsh sesarmid crab Clistocoeloma sinense in small populations of the isolated metapopulation of Tokyo Bay, Japan 1, 2 TAKESHI YUHARA * & TOSHIO FUROTA 1 Department of Environmental Science, Graduate School of Science, Toho University, Funabashi, Chiba 274–8510, Japan 2 Faculty of Sciences, Tokyo Bay Ecosystem Research Center, Toho University, Funabashi, Chiba 274–8510, Japan Received 2 October 2013; Accepted 17 March 2014 Abstract: The saltmarsh sesarmid crab, Clistocoeloma sinense, inhabits the muddy substrata in upper intertidal saltmarshes, and is designated as endangered in Japan. Seasonal changes were investigated in population characters, including abundance, time to sexual maturity, reproductive season, and recruitment of juveniles in a regional meta- population in Tokyo Bay. Crab samples were collected monthly at five small isolated habitats along the coast of the bay from July, 2011, to March, 2013. Ovigerous females were found during summer in a single peak, and a peak of ju- venile recruitment occurred in autumn. Size distribution analysis indicates that growth is slower than for other salt- marsh crab species and life span is at least 4 years. Females reach maturity when they enter the second breeding sea- son following recruitment. The slow growth and reclusive behavior of C. sinense may be closely related to the charac- teristics of its habitat which is under buried stones or wood in the uppermost part of intertidal muddy substrata. Re- cruitment of juveniles and the presence of breeding females were observed at all five study sites located along the Tokyo Bay coastline, suggesting that each population stably regenerates by larval settlement following larval disper- sal and growth in the water column in Tokyo Bay. -

Kameo et al. Progress in Earth and Planetary Science (2020) 7:36 Progress in Earth and https://doi.org/10.1186/s40645-020-00355-x Planetary Science RESEARCH ARTICLE Open Access Calcareous nannofossil biostratigraphy of the Lower–Middle Pleistocene boundary of the GSSP, Chiba composite section in the Kokumoto Formation, Kazusa Group, central Japan, and implications for sea- surface environmental changes Koji Kameo1*, Yoshimi Kubota2, Yuki Haneda3, Yusuke Suganuma4,5 and Makoto Okada6 Abstract The Chiba composite section (CbCS), in the middle of the Boso Peninsula in central Japan, was ratified as the Global Boundary Stratotype Section and Point (GSSP) for the Lower–Middle Pleistocene boundary, accompanied by the Matuyama–Brunhes (M–B) paleomagnetic polarity boundary in January 2020. This study examined the calcareous nannofossil biostratigraphy of the CbCS to describe potential nannofossil events and discuss sea-surface environments around the M–B paleomagnetic polarity boundary. There are no clear biohorizons at the M–B paleomagnetic polarity boundary, although a temporary disappearance of Gephyrocapsa specimens (≥ 5 μmin diameter), an important calcareous nannofossil genus in the Pleistocene, occurs just above the Lower–Middle Pleistocene boundary. Although this is a characteristic event around the M–B paleomagnetic polarity boundary, it is unclear whether the event is globally traceable. Changes in the environmental proxy taxa of calcareous nannofossils in the CbCS revealed that sea-surface environments were driven by glacial-interglacial and millennial-scale climate forces. The time-transgressive change of the Tn value, a calcareous nannofossil temperature index, is mostly concordant with the planktonic foraminiferal oxygen isotope fluctuation. Abundant occurrences of a warm-water species, Umbilicosphaera spp., indicate that the Kuroshio Current was strong after ~ 783 ka. -

Formation in Chiba Prefecture, Japan
ll Lateral change of foraminiferal fauna at the horizon ● just below the tuffaceous key bed, O7, of the Otadai Formation in Chiba Prefecture, Japan Akio Hatta (Received October 8, 1985) Department of Science Education, Faculty of Education, Kagoshima University. K喝oshima 890, Japan Abstract Lateral change of foraminiferal fauna in a siltstone just below a tu打key bed O7 0f the Otadai Format- ion of Chiba Prefecture was investigated traversing the whole breadth of the Boso Peninsula. ● Faunal composition of planktonic Foraminifera of this horizon shows insignificant lateral change (Text-figure 4). This hirizon may belong to N.22 of the Blow (1969)'s zonation scheme, judging from the ranges of Globorotalia tosaensis Takayanagi & Saito, G. hirtuta d'Orbigny and Globigerina parabulloides Blow. The planktonic ratios of this horizon indicate the values between 70.3 and 84.1 %, and this suggests a typical off-shore environment. Faunal composition of benthonic Foraminifera shows significant lateral change (Text-figure 5). The siltstone beneath the O7 bed contains many specimens of deep sea species, such as Bulimina aculeata d'Orbigny, B. nipponica Asano, Bolivina robusta Brady and Uvigerina akitaensis Asano at every locality. Elphidium group and Quinqueloculina group, which are characteristic of shallow water, are very rare m the central part, but increase westward. ● Faunal change of benthonic Foraminifera is scrutinized by using the factor aualysis. The results are interpreted by referring to the distribution of Foraminifera in the adjacent seas of Japan. From the result, it can be thought that the second factor in the g-mode factor analysis is a parameter of abundance of shallow water elements (Table 2 and Text一五gure 6). -

32 Suppl. 1-27.Pdf
Sci. Rep., Niigata Univ. (Geology), No. 32 (Supplement), 1–27, 2017 1 Cenozoic biostratigraphy, chronostratigraphy and paleoceanography in the Boso Peninsula and Bandai Volcano in the Aizu region, East Japan Isao MOTOYAMA*, Takuya ITAKI**, Shin’ichi KAMIKURI***, Yojiro TAKETANI**** and Makoto OKADA***** Abstract The Boso Peninsula is a geologically active region where Cenozoic marine sediments formed in a wide variety of depositional and tectonic environments, including ocean basins, trench, trench-slope basins, forearc basins, and shelf to coastal zones. Radiolarians are key to dating most of these sedimentary rocks. In the northern part of the peninsula, Quaternary sedimentary sequences consisting mainly of siltstone and sandstone crop out along canyons of the Yoro and other rivers. There is no better place in the world than the Yoro canyon to correlate the Pleistocene geomagnetic polarity records to marine micro-biostratigraphy, oxygen isotope records, and radiometric ages from volcanic ash layers. This feature is of great benefit to establishing the boundary stratotype of the lower and middle parts of the Pleistocene Stage. In the more mountainous area to the south, visitors can trace the geological history back to middle Miocene through continuous sedimentary sequences. The earliest fossils imprinted in the rock of the peninsula are of early Cretaceous radiolarians from the Mineoka ophiolite complex. Since the Early Miocene the southern part of the peninsula was covered by seas and close to the trench where the Philippine Sea Plate subducts under the North American Plate. Continual subduction of the oceanic plate resulted in a pile of accreted Miocene sedimentary rocks in the southern part of the peninsula. -
Groundwater, Possibly Originated from Subducted Sediments, in Joban
Togo et al. Earth, Planets and Space 2014, 66:131 http://www.earth-planets-space.com/content/66/1/131 FULL PAPER Open Access Groundwater, possibly originated from subducted sediments, in Joban and Hamadori areas, southern Tohoku, Japan Yoko S Togo1*, Kohei Kazahaya1, Yuki Tosaki1, Noritoshi Morikawa1, Hiroyuki Matsuzaki2, Masaaki Takahashi1 and Tsutomu Sato1 Abstract We studied the origin of deep groundwater in the Joban and Hamadori areas in southern Tohoku, Japan, based on δD, δ18O, 129I/I, 36Cl/Cl, and 3H concentrations. Deep groundwater was collected from the basement rocks (Cretaceous granite) and from the margin of the Joban sedimentary basin (latest Cretaceous to Quaternary sedimentary rocks deposited on the basement rocks). We sampled groundwater pumped from depths ranging from 350 to 1,600 m in these areas. A hypothetical end-member of deep groundwater was estimated from the relationship between δ18O and Cl concentrations, and our data reveal a much higher iodine concentration and lower Br and Cl concentrations than found in seawater. The iodine ages inferred from 129I/I are quite uniform and are about 40 Ma and 36Cl/Cl almost reached the secular equilibrium. The relationship between iodine and Cl can be explained by mixing a hypothetical end-member with meteoric water or seawater. Moreover, the I/Cl ratio increases linearly with increasing water temperature. The water temperature was high in Joban, with a maximum of 78°C at a depth of 1,100 m. The geothermal gradient in the Joban basin is 18°C km−1, and the temperature even at a depth of 3 km in the basin was not high enough to supply thermal water to the sampling sites.
