title: JGR-BNF of Pueraria lobata communities

description: Biological N2 fixation plays crucial roles in determining the pattern and pace of ecological succession and carbon sequestration. Nevertheless, the rates and controls of symbiotic (SNF) and free-living (FNF) N2 fixation have rarely been investigated simultaneously. Here we measured SNF and soil FNF rates for eight early succession ecosystems dominated by kudzu (Pueraria lobata (Willd.) Ohwi) in a subtropical region of China in growing and non-growing seasons. N2 fixation rates were measured using acetylene reduction assay against a 15N2 uptake method. Both SNF and soil FNF rates were significantly (P &lt; 0.05) higher in the growing season than in the non- growing season. The two forms of N2 fixation contributed equally to total N2 fixation rate across the eight sites with soil FNF being higher than SNF in half of the sites. Total N2 fixation rates ranged from 7.12 to 61.93 kg N ha-1 yr-1 with an average of 22.93 ± 6.52 kg N ha-1 yr-1. N2 fixation contributed significantly to soil nitrogen and carbon accumulation. Both SNF and FNF were significantly related to soil moisture. Additionally, SNF and soil FNF were strongly correlated with phosphorus availability and vanadium/iron availability, respectively, mostly likely implying that SNF was limited by phosphorus, and soil FNF was limited by vanadium or iron. Our findings suggest that SNF and soil FNF may be limited by different sets of nutrients within an ecosystem.

title: Growth adaptability and foreign gene stability analysis datasets of 9-year-old TaLEA transgenic Populus simonii × nigra
title: Growth adaptability and foreign gene stability analysis datasets of 9-year-old TaLEA transgenic Populus simonii × nigra

description: In order to improve the survival rate of afforested species in saline–alkali and semi-arid areas, field trial in three sites in Heilongjiang Province of 9-year-old TaLEA transgenic P.simonii × nigra were investigated. The collected tree height and DBH data were investigated by using analysis of variance and multi-site joint analysis. Fresh young leaves of the transgenic lines were extracted and sent to genome resequence. Then we investigated stability of exogenous genes and position of T-DNA insertion. The results suggested that transgenic hybrid poplars of 9-year-old TaLEA lines showed adaptation to drought and saline–alkali conditions. The exogenous gene was expressed normally, and the T-DNA insertion sites were identified on different chromosomes. This datasets contain data of height and DBH of 9-year-old TaLEA transgenic P.simonii × nigra and the results of molecular detection and T-DNA insertion site identification, which can provide reference of testing transgenic trees for future forest production.Five TIF images in the first version of this dataset (V1) can't be previewed online. To facilitate preview and download, the second version of the dataset (V2) changes the image format to JPG, and splits one of the large images.

title: Turn-taking in ASD
title: Turn-taking in ASD

description: Every day social interactions, such as conversations, are characterized by turn-taking, i.e. by the frequent switch between the speaker and listener. Individuals have to coordinate their actions with great precision to achieve such smooth and fast turn-transitions. For this, participants need to predict turn completions and initiate response planning well before the end of an ongoing turn. This study evaluates whether conversational turn-taking is impaired in individuals with autism spectrum disorder (ASD). Participants with ASD and a matched control sample listened to turns, extracted from natural conversations, that could be either predictable or unpredictable. Results indicate that in ASD the linguistic prediction component seems preserved, whereas either initiation of a response or precise timing, or both, are malfunctioning.

title: Arctic sea ice cover product based on spaceborne synthetic aperture radar

description: The Sentinel-1 SAR based sea ice cover data in the Arctic. Based on the U-Net, one kind of architecture of deep learning, we developed a novel method of deriving sea ice cover information from spaceborne SAR data in high spatial resolution. Then we produced the relevant data product based on the ESA Sentinel-1 SAR data acquired in the Arctic using the proposed method. The Sentinel-1A and 1B SAR satellites have been extensively acquired the so-called extra-wide (EW) swath mode data in the polar regions since their launch in 2014 and 2016. The EW data have a wide coverage of approximately 400 by 400 km and a pixel size of 40 by 40 m. The twins can acquired SAR data by approximately 2500 scenes each month in the Arctic. Based on the above-mentioned method, we processed each S1 SAR image acquired in the Arctic and generated the sea ice cover data, which are in the standard CF 1.7 convention of NetCDF. Each S1 image corresponds to a NC file. The spatial resolution of the SAR-derived sea ice cover is 400 m. We have finished processing the S1 data acquired through the year 2019 to 2021 in the Arctic and upload the corresponding sea ice cover data. We are continuing to process the historical data and ongoing acquired data. Therefore, the published data will be updated often.

title: A 3D CT dataset of the skull of Manchurochelys manchoukuoensis (Reptilia: Testudines) from the Early Cretaceous of western Liaoning of China
title: 中国辽西义县早白垩世满洲满洲龟（爬行纲：龟鳖目） 头骨CT扫描数据集

description: Manchurochelys manchoukuoensis is a basal eucryptodires, which is discovered from Early Cretaceous of western Liaoning, and is important for understanding the early evolution of Cryptodira. Four specimens of Manchurochelys manchoukuoensis have been reported, but the holotype is lost. Although this four reported specimens have provided us with important information about Manchurochelys manchoukuoensis, problems are still remained in its anatomical details. The inadequate anatomical knowledge of this species in part impedes a good grasp of character evolution of eucrytodires, and then the phylogenetic interrelationships among these taxa is unresolved. The high resolution micro-CT scans is useful for the anatomical and phylogenetic study of this species. This paper provides a dataset of the micro-CT of the fifth specimen of Manchurochelys manchoukuoensis (PKUP V1071), including original CT slice images, reconstructed three-dimensional CT models of the skull, animated videos. Data for the skull of Manchurochelys manchoukuoensis based on CT scan will contribute to further studies of eucryptodires regarding their morphology and phylogeny. Three-dimensional virtual models of the skull of Manchurochelys manchoukuoensis can be 3D printed, with broad applications in research, teaching, and public education.

title: A dataset of physiological parameters and 13 plant endogenous hormone concentrations with root restriction in 2019-2020
title: A dataset of physiological parameters and 13 plant endogenous hormone concentrations with root restriction in 2019-2020

description: Root restriction, as an efficient cultivation method, has been widely used to promote grapes fruit quality. In China, root restriction cultivation is usually implemented in the production of table grape berries to get higher yield planting in hot and humid environment. It is well known that endogenous plant hormones play an important role in plant growth and development, flowering and ripening, but the effect of root restriction on endogenous plant hormone contents in grape is still unclear. Therefore, it is very important to build a database of grape endogenous hormone contents with root restriction treatment. These data not only provide a reference for the analysis of fruit quality under root restriction, but also lay a theoretical foundation for the variation tendency of grape endogenous hormone contents. In this study, a total of 84 samples (3 biological replicates) were collected from different tissues and organs in different developmental stages of ‘Muscat Hamburg’ grape and analyzed by high performance liquid chromatography (HPLC). Thirteen endogenous plant hormones were identified and a comprehensive dataset of endogenous plant hormones in different organs and developmental stages of ‘Muscat Hamburg’ grape was established. The results provided data support for rapid detection and quantitative analysis of endogenous plant hormones in grape under root restriction cultivation.
