Abstract： The majority of research on eating behaviors has been limited to an almost exclusive focus on pathology and is centered on the female group. Recently, one form of adaptive eating that has gained recognition is “intuitive eating”, which is defined as eating according to internal physiological cues of hunger and satiety rather than external or emotional signals. That is, individuals who eat intuitively are not preoccupied by food and dieting. They often choose food that helps their bodies function well and is pleasing to their palate. They do not ignore hunger cues or classify food into acceptable or unacceptable categories. Therefore, intuitive eating was found to be linked with greater unconditional self-regard and body satisfaction, as well as lower levels of both depression and disordered eating. Adolescence, in particular, acts as a critical period in the development of eating attitudes and behaviors. Adolescents devote a great deal of attention to physical appearance, and are inclined to engage in unhealthy eating behaviors to reduce an unsatisfactory body image; this has a negative impact on their physical and mental health. Due to these circumstances, it is essential to identify the key factors influencing adolescents’ healthy eating behaviors. Using the perspectives of attachment theory and the acceptance model of intuitive eating, this study aimed to investigate the effect of friendship quality on intuitive eating among Chinese adolescents, and the potential mediating role of self-compassion and positive body image on this association, as well as explore a possible gender difference. This research not only provides suggestions for parents and educators to increase adolescents’ intuitive eating, but it also identifies significant factors that influence intuitive eating in order to foster relevant practical prevention strategies and interventions.Participants were 2438 students (M = 13.14 years, SD = 1.08) recruited from three middle schools (Grades 7 to 9) in Wuhan, Hubei Province, China. There were 1162 girls (47.7%) and 1276 boys (52.3%). They completed a set of self-report measures on friendship quality, self-compassion, positive body image, and intuitive eating. All the measures have acceptable reliability and validity. The results indicated that after controlling for age, gender, and body mass index, friendship quality was positively associated with intuitive eating. Self-compassion and positive body image mediated this association, which contained three significant mediating pathways: the separate mediating effects of (a) self-compassion and (b) positive body image, and the serial mediating effect of (c) self-compassion and positive body image. In addition, significant differences in mediating effects per gender were only found in the relationship between friendship quality and the dimensions of intuitive eating (“unconditional permission to eat” and “eating for physical rather than emotional reasons”).Our findings highlight the relevance of friendship quality, self-compassion, and positive body image in the understanding of adolescents’ intuitive eating. This study suggests that parents should create a warm and friendly family atmosphere which will contribute to adolescents’ peer relationships and friendships. Educators should direct students to be compassionate toward their own shortcomings and failures to improve levels of body appreciation and body satisfaction. These factors will play important roles in promoting intuitive eating. Moreover, future interventions for intuitive eating should be designed to increase adolescents’ self-compassion and positive body image through effective intervention approaches and measures.

Abstract：干旱是全球范围内影响最为广泛的自然灾害之一，其所导致的土壤沙漠化、荒漠化和盐碱化给生态环境造成不可逆的危害。通过对MODIS数据进行投影转换、去云等预处理的基础上，利用地形校正对[WTBX]TVDI模型进行改进，构建了改进型的温度植被干旱指数（mTVDI）用于新疆干旱区旱情监测。利用土壤实测数据对mTVDI及传统的TVDI模型进行对比验证。研究结果表明：（1） 利用EVI与校正后的LST构建的mTVDIE对干旱区旱情的敏感度最高，与实测土壤水分数据的相关性R2为0.74。（2） 从空间上看，新疆2015年旱情分布以塔里木盆地和准噶尔盆地为两个干旱中心，旱情状况由严重逐步向周围山区递减至湿润状态。从时间上看，新疆6月、7月和8月旱情最为严重。（3） 研究利用TRMM降水数据对基于mTVDIE反演的新疆旱情时空分布特征进行对比分析，结果表明二者所表现出的旱情时空分布较为一致，不同时间段内的降水量与mTVDIE之间具有一定的相关性，且均通过了P<0.01显著性检验。综上，基于TVDI所提出的mTVDIE 能够有效开展新疆干旱区旱情监测，且精度较高，从而为今后定量化开展大区域尺度旱情监测研究提供参考。

Abstract： Aims Accurate estimation of carbon density and storage is among the key challenges in evaluating ecosystem carbon sink potentials for reducing atmospheric CO2 concentration. It is also important for developing future conservation strategies and sustainable practices. Our objectives were to estimate the ecosystem carbon density and storage of Picea schrenkiana forests in Tianshan region of Xinjiang, and to analyze the spatial distribution and influencing factors. Methods Based on field measurements, the forest resource inventories, and laboratory analyses, we studied the carbon storage, its spatial distribution, and the potential influencing factors in Picea schrenkiana forest of Tianshan. Field surveys of 70 sites, with 800 m2 (28.3 m × 28.3 m) for plot size, was conducted in 2011 for quantifying arbor biomass (leaf, branch, trunk and root), grass and litterfall biomass, soil bulk density, and other laboratory analyses of vegetation carbon content, soil organic carbon content, etc. Important findings The carbon content of the leaf, branch, trunk and root of Picea schrenkianais varied from 46.56% to –52.22%. The vegetation carbon content of arbor and the herbatious/litterfall layer was 49% and 42%, respectively. The forest biomass of Picea schrenkiana was 187.98 Mg?hm–2, with 98.93% found in the arbor layer. The biomass in all layers was in the order of trunk (109.81 Mg?hm–2) > root (39.79 Mg?hm–2) > branch (23.62 Mg?hm–2) > leaf (12.76 Mg?hm–2). From the age-group point of view, the highest and the lowest biomass was found at the mature forest (48.70 Mg?hm–2) and young forest (30.72 Mg?hm–2), respectively. The carbon density and storage were 544.57 Mg?hm–2 and 290.84 Tg C, with vegetation portion of 92.57 Mg?hm–2 and 53.14 Tg C, and soil portion of 452.00 Mg?hm–2 and 237.70 Tg C, respectively. The spatial distribution of carbon density and storage appeared higher in the western areas than those in the eastern regions. In the western Tianshan Mountains (e.g., Yili), carbon density was the highest, whereas the central Tianshan Mountains (e.g., Manasi, Fukang, Qitai) also had high carbon density. In the eastern Tianshan Mountains (e.g., Hami), it was low. This distribution seemed consistent with the changes in environmental conditions. The primary causes of carbon density difference might be a combined effects of multiple environmental factors such as terrain, precipitation, temperature, and soil.

Abstract： Picky eating is a common dietary issue among children characterized by lack of variety of foods consumed due to rejection of familiar (or unfamiliar) foods. The influencing factor model of picky eating behavior in children indicates that environmental and cognitive factors are key elements influencing this. Studies have found that instrumental feeding exacerbates picky eating behavior in children. However, due to the relatively young age of children in previous studies, research on the relationship between instrumental feeding and picky eating behaviors in school-aged children is insufficient. Furthermore, the brain plays a central role in guiding eating behavior; however, to date, limited neuroscientific research on the neural basis of picky eating behaviors in school-aged children exists. This study aimed to utilize resting-state functional magnetic resonance imaging (rs-fMRI) data combined with a machine learning method to explore the neural basis of picky eating behaviors in children. Additionally, it attempted to show the neural mechanisms through which instrumental feeding influences picky eating behavior.
A total of 139 children were recruited for this study. Instrumental feeding and picky eating behaviors were assessed through parent-reported measurements and rs-fMRI was conducted. A total of 87 children were included in the formal analyses as those who did not participate in the two behavioral measurements and with unqualified rs-fMRI scans were excluded. This study utilized regional homogeneity and functional connectivity to evaluate the resting-state neural substrates of picky eating behaviors. Subsequently, a machine learning method is employed to validate the stability of our results. Additionally, a mediation model was constructed to investigate the mediating role of resting-state neural substrates in the relationship between instrumental feeding and picky eating behavior.
Results showed that picky eating behavior was positively correlated with regional homogeneity in the right caudate. Functional connectivity results showed that picky eating behavior was positively correlated with functional connectivity between the right caudate and left putamen. A prediction analysis based on a cross-validation machine learning method indicated a significant correlation between picky eating behavior scores predicted by the aforementioned neural substrates (i.e., regional homogeneity in the right caudate and functional connectivity between the right caudate and left putamen) and the actual observed picky eating behavior scores. The mediation model further suggested that functional connectivity between the right caudate and left putamen could mediate the relationship between instrumental feeding and picky eating behavior. Specifically, instrumental feeding might negatively influence the functional connectivity between the right caudate and left putamen, and further reduce picky eating behavior.
By combining resting-state regional homogeneity and functional connectivity analyses, this study detected altered functional brain activity related to picky eating behaviors in children aged 9 to 12. Specifically, hyperactive neural interactions within the brain areas involved in sensory sensitivity and reward processing may explain the manifestation of picky eating behavior in children. Additionally, instrumental feeding negatively influences picky eating behavior through brain activity in regions involved in sensory sensitivity and reward processing. This study provides new insights into the resting-state neural substrates of children's picky eating behavior, extends the influencing factor model of children's picky eating behavior, and provides theoretical support for interventions to improve poor picky eating behavior in children through parental feeding practices.

Abstract： Early life stress (ELS) has been used to describe a broad spectrum of adverse and stressful events, including childhood trauma occurring during neonatal life, early and late childhood, and adolescence. Childhood is a vulnerable time point for stressful events due to an immature brain, which increases the risk of psychopathology in later life. However, to date, studies have focused almost exclusively on adolescents and adults, and little is known about the relationship between ELS and the structural and functional brain changes in children. Here, we adopted a multimodal approach combining voxel-based morphometry (VBM) and functional connectivity (FC) to examine the neural substrates of ELS in children aged 9~12 years.A total of 139 children were recruited for this study. For each participant, the ELS level was assessed and an 8-minute rs-fMRI scan was performed using a 3T Trio scanner. Participants with unqualified data were excluded, resulting in a final sample of 78 participants (39 females; mean age = 10.18). For statistical analysis, we used the gray matter volume (GMV) and FC to explore the brain structural and functional correlates of children’s ELS and then used a machine learning method to investigate whether and how structural connectivity profiles in predefined brain networks can predict ELS levels. Additionally, exploratory analyses were performed to investigate potential sex differences and age characteristics in GMV and FC associated with children’s ELS. VBM analysis showed that greater ELS was associated with a larger GMV in the left medial orbitofrontal cortex, right insular cortex, left superior temporal gyrus, and left supplementary motor area. Subsequently, we used these clusters as seed regions to analyze the correlation between FC and stress in children. We found that greater ELS was associated with lower insular-inferior parietal lobule (IPL) connectivity. The results were not influenced by sex, age, total intracranial volume, or head motion. Furthermore, the predictive analysis of machine learning reported that the sensorimotor, frontoparietal, salience, visual, and cerebellar networks could marginally predict ELS scores. Finally, exploratory analyses showed that there were no significant sex differences in the GMV or FC associated with ELS and that significant correlations of ELS with the GMV of the inferior occipital gyrus were mainly manifested in 9-year-old children. Using VBM and FC analyses, we detected structural and functional brain alterations associated with ELS in children aged 9~12 years. Specifically, the VBM analysis mainly reflected that children with high ELS may have abnormal emotional and cognitive functions, such as hypersensitivity to emotional stimuli and over-monitoring of their own behavior. In addition, FC analysis indicated that aberrant interaction of internal and external information may contribute to high ELS in childhood. This study not only provides unique insights into the neural substrates of ELS but may also help identify children who are susceptible to ELS within the general population, which may be advantageous for early prevention strategies and interventions for children.
