Biogeographic divides in East Asia delineated by the three-step landforms of China and the East China Sea: insights from phylogeographical breaks of Kerria japonica
<p><span><b>Aim: </b>East Asia exhibits complex geomorphological and climatic characteristics. The aim </span>of this study is to test whether the biogeographic divides present along the so-called three-step landforms of China and the East China Sea (ECS), and provide insight into the evolution the East Asian Flora (EAF) with respect to Hengduan Mountains, Central China and East China.</p> <p><span><span><b>Location:</b> East Asia</span></span></p> <p><span><span><b>Taxon: </b><i>Kerria japonica</i>, a deciduous shrub distributed in subtropical mixed evergreen and deciduous broadleaved forests of East Asia.</span></span></p> <p><span><b>Methods: </b>Three chloroplast DNA (cpDNA) regions and 15 nuclear microsatellite (nSSR) loci were sequenced/genotyped in 576/450 individuals. We performed phylogeographical analyses to assess genetic structure, historical gene flow and demographic history. Climate factors were examined to identify their effects on the phylogeographical breaks. Time</span>-calibrated phylogenetic trees and ancestral range reconstruction<span> were used to infer biogeographic history. Potential habitats at present and in the past (LIG, LGM) were identified using ecological niche modelling (ENM).</span></p> <p><span><b>Results: </b>Distinct phylogeographical breaks were found along the ECS and the edges of the three-step landforms of China. Low historical gene flow and significant climatic differences were detected in each pair of adjacent regions. Compared with the quite stable distribution range on the Chinese mainland, Japanese populations had experienced obvious northward expansion after the LGM in response to Quaternary climate change.</span></p> <p><span><b>Main conclusions: </b><i>K. japonica</i> has a complex biogeographic history, with a Mid-Miocene origin in North America and subsequent migration into East Asia via the Bering land bridge. The onset of intra-specific diversification was probably associated with the Asian monsoon intensifications, while the CJK land bridge facilitated the formation of the Japan lineage (6.78 Ma). The spatiotemporal population differentiation in Chinese mainland demonstrates the significant role of biogeographic divides delineated by three-step landforms of China; and provides clues to help understand the floristic regionalization and evolutionary history of plant diversity in East Asia, especially with respect to the Hengduan Mountains, Central China and East China.</span></p>
Molecular Formulas of Organic Aerosols at Two Sites of East China
<p>In this dataset we present molecular composition of organic aerosols collected at Xiangshan gulf (29°29′ N, 121°46′ E) and an inland urban site (32°20′ N, 118°71′ E) of east China. Compound formula, mass-to-charge ratio, mass error between measured and theoritical values, intensity and adduct form are measured using a FT-ICR-MS with a high size resolution.</p>

Data from: Ecological stasis in Spinicaudata (Crustacea, Branchiopoda)? Early Cretaceous clam shrimp of the Yixian Formation of north‐east China occupied a broader realized ecological niche than extant members of the group
The palaeoecology of Spinicaudata, the dominant group of benthic invertebrates in many pre-Cenozoic freshwater environments, remains poorly understood. In analogy with extant taxa, it has been oversimplified and often reduced to shallow, temporary environments characterised by few trophic levels, implying ecological stasis from the Devonian to the Recent. We excavated 43 horizons of the Lower Cretaceous Yixian Formation (Anjiagou and Hengdaozi beds) to evaluate whether spinicaudatan ecology can be simplified to such an extent. Sedimentological evidence suggests general perennial conditions during the excavated lake interval. Based on 33,226 specimen counts, we identified three arthropod-dominated macrobenthic associations and two assemblages. Response curves indicate that the spinicaudatan Eosestheria middendorfii was exceptionally tolerant to environmental gradients, followed, in decreasing order, by mayfly larvae, water boatmen and oligochaetes. Also, many spinicaudatan-yielding layers represent death after reproductive senescence rather than mass-mortality events. Spinicaudatan size varies significantly according to faunal association. A forward stepwise regression model suggests that growth responded to population density and diversity: lower densities and higher diversities triggered fast growth, and vice versa. The proposed strong density effect on carapace size has been corroborated by rearing experiments: As for E. middendorfii, natural log regression provided the best fit for the two extant species Eulimnadia texana and Eocyzicus argillaquus. Hence, Eosestheria middendorfii was a tolerant and morphologically variable species adapted to perennial waters and the frequent presence of higher trophic levels. Although there are rare records of extant taxa co-occurring with fish, the described Early Cretaceous environment is commonly not realized by extant Spinicaudata.
