“…On the Sea of Japan side of western Japan, the post‐glacial changes in vegetation (deciduous broadleaf forests to evergreen broadleaf forests to Cryptomeria forests) were very similar to those in the last interglacial period (MIS 5e, Kinki region in Figure 3), suggesting that orbital climate conditions may have affected the development of the Cryptomeria population in the Late Holocene, wherein there was high precipitation during all seasons and stable temperatures with relatively low seasonal differences (Hayashi et al, 2021), conditions typical of a moist oceanic climate.…”

The natural distribution of Japanese cedar (Cryptomeria japonica) has been disturbed by human activities, owing mainly to its value as timber; thus, its position in the vegetation zone of Japan is not clear. Therefore, it is important to determine the history of C. japonica forests before human influence. We reviewed the transitions in distribution and abundance of C. japonica in the Japanese Archipelago since the last interglacial period by using published pollen data. During the last interglacial, temperate deciduous broadleaf forests developed on northeastern Honshu Island, whereas on southwestern Honshu Island C. japonica populations increased, accompanied by warm-temperate evergreen broadleaf trees. During the first half of the last glacial period, C. japonica forests developed throughout the Japanese Archipelago except on Hokkaido. Thereafter, 60,000-30,000 years ago, C. japonica covered the area around Lake Biwa and the Izu Peninsula. During the Last Glacial Maximum, C. japonica was most abundant on the Izu Peninsula, and small refugial populations were located along the coast of the Sea of Japan from southwestern to northeastern Honshu, and along the Pacific coast of Shikoku Island. During the Middle Holocene, C. japonica populations increased rapidly in southwestern Honshu. Two thousand years ago, before the intensification of human activities, C. japonica was widespread in warm-to cool-temperate zones on the Sea of Japan side of Honshu, the Izu Peninsula, the Pacific coast of Shikoku Island, and Yakushima Island. This evidence indicates that C. japonica is one of the major tree species in the Japanese vegetation zone.

“…The oceanography of the Bay of Bengal is influenced by the distinct seasonality of the Indian monsoon winds and the large amount of fresh water along with lithogenic particles was discharged from the Ganga-Brahmputra-Meghna (GBM) River system. For example, Rixen et al (2019) observed seasonal variations in particulate organic carbon (Kawamura et al, 2006), PS2489-2 (Becquey & Gersonde, 2002), Ocean Drilling Program (ODP) Site 716 (Gupta et al, 2010), and International Ocean Discovery Program Site U1427 (Hayashi et al, 2021).

“…In addition, long-term terrestrial climatic changes have been reported in other remote areas at similar times during MBDI. At IODP Site U1427 (off the northern coast of southwestern Japan), Hayashi et al (2021) reported that the pollen temperature index (Tp ratio) and the relative abundance of Cryptomeria showed alternating fluctuations from MIS 9 (Figure 6). The onset of such inverse fluctuations was attributed to a shift in the periodicity of the East Asian monsoon related to a precession-induced insolation change across the mid-Brunhes event.…”

We investigated benthic foraminifera in cores GPC03 and GPC04 in the northeast tropical Indian Ocean (TIO) over the past ∼450 ka to evaluate the ballasting effect of particulate organic matter (POM) and the long‐term zonal change during the mid‐Brunhes dissolution interval (MBDI). Today, interannual climate and oceanographic variability in the TIO is governed by the Indian Ocean Dipole (IOD), which manifests as asymmetric zonal oceanographic change. Previous studies have been conducted to uncover such zonal paleoceanographic change and have referred to their climatic pattern as an “IOD‐like mode.” In the northeast TIO, after ∼390 ka, contributions of lithogenic matter and %Nuttallides umbonifer were unusually high under the better carbonate preservation conditions during glacial periods. Our findings suggest that the effect of lithogenic matter from the Ganga‐Brahmaputra‐Meghna River system increased significantly under glacial low sea‐level conditions, possibly by lateral transport along the continental slope. As a result, ballasting of POM seemed more efficient during glacial periods by abundant riverine lithogenic particles. In addition, the long‐term (∼320–200 ka) trend of high benthic foraminiferal accumulation rate (BFAR) and several short‐term fluctuations of high BFAR at ∼310, ∼280, ∼260, and ∼240 ka were discernible. We attribute these changes to increased paleoproductivity driven by upwelling, which may be related to the Indian Ocean equatorial westerlies and Indian summer monsoon dynamics via variations arising from precession. We propose that a long‐term mean‐state transition of IOD‐like mode might have occurred during the MBDI, similar to other hypotheses invoking concomitant changes in the El Niño‐Southern Oscillation system.
