| 2 | Soil respiration in tropical seasonal rain forest in Xishuangbanna, SW China显示文摘With the static opaque chamber and gas chromatography technique, from January 2003 to January 2004 soil respiration was investigated in a tropical seasonal rain forest in Xishuangbanna, SW China. In this study three treatments were applied, each with three replicates: A (bare soil), B (soil+litter), and C (soil+litter+seedling). The results showed that soil respiration varied seasonally, low from December 2003 to February 2004, and high from June to July 2004. The annual average values of CO2 efflux from soil respiration differed among the treatments at 1% level, with the rank of C (14642 mgCO2· m-2. h-1)>B (12807 mgCO2· m-2. h-1)>A (9532 mgCO2· m-2. h-1). Diurnal variation in soil respiration was not apparent due to little diurnal temperate change in Xishuangbanna. There was a parabola relationship between soil respiration and soil moisture at 1% level. Soil respiration rates were higher when soil moisture ranged from 35% to 45%. There was an exponential relationship between soil respiration and soil temperature (at a depth of 5cm in mineral soil) at 1% level. The calculated Q1o values in this study,ranging from 2.03 to 2.36, were very near to those of tropical soil reported. The CO2 efflux in 2003was 5.34 kgCO2· m-2. a-1 from soil plus litter plus seedling, of them 3.48 kgCO2· m-2. a-1 from soil (accounting for 62.5%), 1.19 kgCO2· m-2. a-1 from litter (22.3%) and 0.67 kgCO2·m-2. a-1 from seedling (12.5%). | SHA Liqing, ZHENG Zheng, TANG Jianwei, WANG Yinghong, ZHANG Yiping, CAO Min, WANG Rui, LIU Guangren, WANG Yuesi & SUN Yang Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, Kunming 650223, China Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100029, China Graduate School of Chinese Academy of Sciences, Beijing 100039, China | 2005 | Science China Earth Sciences2005，48，z1： | 12 |
| 3 | Contrasting effects of space and environment on functional and phylogenetic dissimilarity in a tropical forest显示文摘Aims The evolutionary history and functional traits of species can illumi-nate ecological processes supporting coexistence in diverse forest communities.However,little has been done in decoupling the rela-tive importance of these mechanisms on the turnover of phylogenetic and functional characteristics across life stages and spatial scales.Therefore,this study aims to estimate the contribution of environment and dispersal on the turnover of phylogenetic and functional diversity across life stages and spatial scales,in order to build a coherent pic-ture of the processes responsible for species coexistence.Methods We conducted the study in Xishuangbanna Forest Dynamics Plot in Yunnan Province,southwest China.We used four different spatial point process models to estimate the relative importance of disper-sal limitation and environmental filtering.The functional traits and phylogenetic relationships of all individual trees were incorporated in the analyses to generate measures of dissimilarity in terms of pair-wise and nearest-neighbor phylogenetic and functional characteris-tics across life stages and spatial scales.Important Findings We found non-random patterns of phylogenetic and functional turnover across life stages and spatial scales.Environmental filtering structured pairwise phylogenetic and functional beta diversity across spatial scales,while dispersal limitation alone,and in combination with environment filtering,shaped nearest neighbor phylogenetic and functional beta diversity.The relative importance of dispersal limitation and environmental filtering appeared to change with life stage but not with spatial scale.Our findings suggest that phylogenetic and functional beta diversity help to reveal the ecological processes responsible for evolu-tionary and functional assembly and highlight the importance of using a range of different metrics to gain full insights into these processes. | Mengesha Asefa Calum Brown Min Cao Guocheng Zhang Xiuqin Ci Liqing Sha Jie Li Luxiang Lin Jie Yang | 2019 | Journal of Plant Ecology2019，12，2： | 3 |

| 6 | The potential for biochar application in rubber plantations in Xishuangbanna,Southwest China:a pot trial显示文摘Biochar can enhance crop production and sequester carbon,but there have been few studies with tree crops.Rubber plantations cover more than 8 million hectares in Southeast Asia,so we assessed the feasibility of biochar application in these plantations with a pot trial.Rubber seedlings were planted in soil with four concentrations(0,1.25%,2.5% and 5%,w/w)of biochar combined with two concentrations of compound fertilizer(0 kg/ha and 300 kg/ha).Soil properties and seedling growth were measured,and a leaching experiment was conducted in the rainy season.Our results show that biochar increased pH,water content(27.4-65.1%),total carbon(25.4-53.6%),nitrate nitrogen,and available phosphorus in the soil,and decreased bulk density(3.2-23.9%).Biochar treatment reduced leaching of ammonium nitrogen and ortho-P.Biochar increased seedling nutrient uptake(C,N,P and K),with 2.5% and 5% biochar showing the largest effects,but seedling biomass was the highest with 1.25%,and declined in 2.5% and 5%.Our results suggest that biochar addition is an effective way to improve rubber plantation soils,sequester more carbon and decrease nutrient leaching,but the optimum application rate under field conditions needs further research. | Libing Pan Fanzhen Xu Huizhu Mo Richard T.Corlett Liqing Sha | 2021 | Biochar2021，3，1： | 0 |
| 7 | Construction of a transposase accessible chromatin landscape reveals chromatin state of repeat elements and potential causal variant for complex traits in pigs显示文摘Background:A comprehensive landscape of chromatin states for multiple mammalian tissues is essential for elucidating the molecular mechanism underlying regulatory variants on complex traits.However,the genome-wide chromatin accessibility has been only reported in limited tissue types in pigs.Results:Here we report a genome-wide landscape of chromatin accessibility of 20 tissues in two female pigs at ages of 6 months using ATAC-seq,and identified 557,273 merged peaks,which greatly expanded the pig regulatory ele-ment repository.We revealed tissue-specific regulatory elements which were associated with tissue-relevant biologi-cal functions.We identified both positive and negative significant correlations between the regulatory elements and gene transcripts,which showed distinct distributions in terms of their strength and distances from corresponding genes.We investigated the presence of transposable elements(TEs)in open chromatin regions across all tissues,these included identifications of porcine endogenous retroviruses(PERVs)exhibiting high accessibility in liver and homology of porcine specific virus sequences to universally accessible transposable elements.Furthermore,we prior-itized a potential causal variant for polyunsaturated fatty acid in the muscle.Conclusions:Our data provides a novel multi-tissues accessible chromatin landscape that serve as an important resource for interpreting regulatory sequences in tissue-specific and conserved biological functions,as well as regula-tory variants of loci associated with complex traits in pigs. | Tao Jiang Ziqi Ling Zhimin Zhou Xiaoyun Chen Liqing Chen Sha Liu Yingchun Sun Jiawen Yang Bin Yang Jianzhen Huang Lusheng Huang | 2023 | Journal of Animal Science and Biotechnology2023，14，2： | 0 |
| 8 | Effects of Seasonal and Perennial Grazing on Soil Fauna Community and Microbial Biomass Carbon in the Subalpine Meadows of Yunnan, Southwest China显示文摘Grazing and over-grazing may drive changes in the diversity and functioning of below-ground meadow ecosystems. A field soil survey was conducted to compare microbial biomass carbon(Cmin) and soil fauna communities in the two main grassland management systems in subalpine regions of Yunnan Province, China: perennial grazing currently practiced due to increasing herd sizes and traditional seasonal grazing. A three-year exclosure experiment was then conducted to further compare the effects of different grazing practices,including treatments of no mowing, perennial grazing(NM + G), mowing followed by seasonal grazing(M + G), mowing and no grazing(M + NG), and no mowing or grazing(NM + NG). The comparative survey result revealed that Cminand total density of soil fauna were significantly lower at a perennially grazed site than at a seasonally grazed site. The experiment results showed that in comparison to non-grazing treatments(M + NG and NM + NG), grazing(NM + G and M + G) reduced total fauna density(by 150 individuals m^(-2)) and the number of taxonomic groups present(by 0.32 taxa m^(-2)). Mowing decreased Cmin(by 0.31 mg g^(-1)). Furthermore, the NM + G treatment(perennial grazing) had the lowest density of Collembola(16.24 individuals m^(-2)), one of the two most common taxonomic groups, although other taxonomic groups responded differently to the treatments. Treatment effects on soil fauna were consistent with those on above-ground grasses, in which C:N ratios were greatly reduced by grazing, with this effect being the greatest for the NM + G treatment. In contrast, different grazing treatments had little effect on C:N ratio of soil. Furthermore, the traditional grazing method(mowing followed by seasonal grazing) may have less severe effects on some taxonomic groups than perennial grazing. Therefore, an appropriate management should aim to protect soil fauna and microbes in this area from over-grazing and against further degradation. | LIU Shengjie YANG Xiaodong Anthony R.
