Re-examination of coastal submergence events during the last 4000 years in the Ukishima-ga-hara lowland, central Japan: an aid for the long-term evaluation of the Fujikawa-kako fault zone Open
As many as twenty submergence events over the past 4000 years have been identified in Ukishima-ga-hara, a lowland facing the Suruga Trough in central Japan. We obtained 17 cores 5–25 m long from the reclaimed area, along with a 15 m core a…

Are disjunct populations of <i>Betula costata</i> in the Japanese Archipelago glacial relict? An attempt at verification by species distribution modeling Open
A glacial relict, a remnant of a cold‐adapted species or population from a postglacial retreat, is essential for understanding the formation processes of present‐day vegetation. Although past distributions have been reconstructed for sever…

Higher palaeoelevation in the Baoshan Basin: Implications for landscape evolution at the southeastern margin of the Tibetan Plateau Open
Surface uplift at the southeastern margin of the Tibetan Plateau has been widely studied, but more palaeoaltimetry data are required to better understand the elevation history of this geologically complex region. In this study, fossil leav…

Wildfire associated with a deciduous broadleaved forest from the Neogene Baoshan Basin at the southeastern margin of the Tibetan Plateau Open
Wildfire bears a close relationship with vegetation as its fuel source. The southeastern margin of the Tibetan Plateau witnesses frequent wildfires among various types of vegetation, whereas such wide interactions between wildfire and vege…

Climate change impacts on migration of Pinus koraiensis during the Quaternary using species distribution models Open
Clarifying the influences of paleoclimate changes on the disjunct distribution formation of plants allows a historical and mechanical understanding of current vegetation and biodiversity. This study investigated the influences of paleoclim…

Forest characteristics and population structure of Glyptostrobus pensilis, a globally endangered relict species of southeastern China Open
The Chinese water pine Glyptostrobus pensilis is the sole surviving species of the genus Glyptostrobus. It is endemic to southern China, central Vietnam, and eastern Laos, and today it is nearly extinct in the wild. Forest community charac…

Author Correction: Identifying long-term stable refugia for relict plant species in East Asia Open
In the original version of this Article, an incorrect sample size was provided for the number of relict species (443 instead of 442) and the number of relict forests (423 instead of 422). These errors have been corrected in both the PDF an…

Identifying long-term stable refugia for relict plant species in East Asia Open
Today East Asia harbors many “relict” plant species whose ranges were much larger during the Paleogene-Neogene and earlier. The ecological and climatic conditions suitable for these relict species have not been identified. Here, we map the…

Past and future global transformation of terrestrial ecosystems under climate change Open
Future predictions from paleoecology Terrestrial ecosystems will be transformed by current anthropogenic change, but the extent of this change remains a challenge to predict. Nolan et al. looked at documented vegetational and climatic chan…

Fruit fossils of Rosoideae (Rosaceae) from the late Pliocene of northwestern Yunnan, Southwest China Open
The subfamily Rosoideae Focke (Rosaceae) has a good fossil record in the Northern Hemisphere, but these fossil records are confined mainly to a few genera, whereas the majority, in particular those with herbaceous members, are still under‐…

中部日本とその周辺の鮮新・更新世の地形発達が植物相と植生の変遷に与えた影響について総説した．下部更新統菖蒲谷層ではメタセコイアが氷期の化石群にも含まれていることから，メタセコイアの日本からの絶滅要因として気候よりむしろ生育場所の地形の変化が考えられた．近畿地方中部では植物の絶滅と冷温帯の植物群の出現の時期が，堆積盆地周辺の古地形の変化と良く対応していた．これらのことを検証するために，堆積盆地周辺の古地形に対応した植物の分布を，植物化石群の形成過程を考慮して復元した．日本から…

日本列島における「弥生の小海退」は,その存在が認められる地域と認められない地域が明確になっておらず,その存在が報告された地域においても,海水準インデックス・ポイントが連続的に得られていないことに問題がある.筆者らは,利根川低地最奥部において,水深が約1~2mと推定され,3~2cal kyr BPの海水準上昇に伴って形成されたと考えられる湖沼堆積物を発見した.その堆積年代と分布深度は,水深を推定値の最大の2mと仮定しても,海水準が3.0cal kyr BPには標高-2.2mま…
