  • First report of Hispanodorcas from the Late Miocene of China

    分类: 生物学 >> 动物学 提交时间: 2024-01-28 合作期刊: 《古脊椎动物学报》

    摘要: 西班牙羚(Hispanodorcas)是一类中小型牛科动物,此前只在泛地中海地区和南亚有 所发现。西班牙羚的分类一直有所争议,曾被认为与羚羊族(Antilopini), 苇羚族(Reduncini) 或角羊族(Oiocerini)有关。报道了在中国庆阳正宁地区的代店化石点首次发现的陇东西班 牙羚新种(H. longdongica sp. nov.), 时代大约为早保德期(约87百万年前)。新材料包括5个头 骨,保存状态各异,提供了迄今为止关于西班牙羚最完整的骨骼信息。其角心长而细、向 后弯曲,且微弱地同向扭曲(homonymous twist); 角心同时还具有和外背侧沟和内腹沟, 这些都是西班牙羚的典型特征。代店地点发现的西班牙羚在已知各种中体型最小,面部和 脑颅之间的弯曲较弱,前后基结节均发育较弱。这些原始的特征表明陇东西班牙羚可能代表了这个属的早期演化阶段。此外,该种头骨与瞪羚(Gazella)的相似之处表明西班牙羚可 能是直接从瞪羚的祖先演化而来,其同向扭转的角心与角羊族一致,可能是两者平行演化 所致。

    摘要: 目的:通过分析小鼠自主食用不同甜味物质后尿液蛋白质组的变化,探索其对机体的可能影响。方法:收集C57BL/6l小鼠主动食用甜味物质前后的尿液样品。甜味物质包括目前世界范围内应用较为广泛且能引起小鼠喜好反应的蔗糖、甜菊糖苷、安赛蜜、三氯蔗糖,其中非营养性甜味剂的浓度选择了已有研究显示的小鼠喜好反应最强烈的浓度。通过高效液相色谱串联质谱联用(LC-MS/MS)的非标记定量蛋白质组学技术进行分析,成组筛选尿液蛋白质组的差异蛋白,进行蛋白质功能和生物学过程分析;进行单只小鼠食用甜味物质前后尿液蛋白质组比较;并将不同甜味物质进行横向对比。结果及结论:尿液蛋白质组可以反映小鼠自主食用甜味物质后的机体变化,且小鼠自主食用的不同甜味物质对尿液蛋白质组的影响并不相同。4种甜味物质中,三氯蔗糖与蔗糖引起机体的变化最为相似,甜菊糖苷与蔗糖引起机体的变化相差最远;蔗糖、安赛蜜和三氯蔗糖引起的机体变化相似,而甜菊糖苷引起机体的变化与其他甜味物质不同。小鼠自主食用4种甜味物质后尿液蛋白质组差异蛋白中均有已经被报道的与脑奖励回路相关的蛋白,而只有自主食用蔗糖、安赛蜜和三氯蔗糖后尿液蛋白质组差异蛋白大量与代谢过程相关,自主食用甜菊糖苷后尿液蛋白质组差异蛋白主要与核小体组装、基因表达等过程相关。

  • eDNA监测测序数据分析注释中参考数据库选择、指标阈值选择、目标数据准备的影响——以长江中游鱼类为监测目标

    分类: 生物学 >> 生态学 提交时间: 2024-01-23

    摘要: 在基于宏条形码(meta-barcoding)的eDNA监测技术路径中,eDNA测序数据的分析和注释是决定监测结果判断和评估精确与否甚至准确与否的基础,而参考数据库选择、指标阈值选择、目标数据准备是eDNA测序数据分析和注释中最为关键的3个技术环节。为弄清上述3个技术环节处理方案的影响,本研究以长江中游2组eDNA监测COI基因测序数据为分析对象,针对鱼类的检出做了3组实验来分别检验1)不同参考数据库及物种注释算法对注释结果的影响,2)不同OTU聚类序列相似度和物种注释分类置信度(序列一致性和序列覆盖度)对注释结果的影响,3)目标数据中各物种不同序列丰富度对注释结果的影响。结果显示:1)Blast算法下,3个版本nt库注释出的物种基本一致(72%~78%),2个本地序列参考库注释出的物种也基本一致(91%~96%),这5个序列参考库注释出的物种52%~68%一致;nt库RDP Classifier算法注释出的物种覆盖95%以上Blast算法注释出的物种,并比Blast算法注释出的物种多151%~443%,多出的物种大都是错误注释,本地参考数据库RDP Classifier算法注释出的物种覆盖66%~85%的Blast算法注释出的物种,并存在数条只注释到科属的结果。2)OTU聚类序列相似度阈值,取值0.999比取值0.99获得的OTU多154%~209%,注释到鱼类的OTU多240%~490%;注释分类置信度阈值(Blast算法,序列一致性和序列覆盖度)从0.8到0.99注释获得的物种组成基本(94%以上)一致,物种下的OTU组成也基本(83%以上)一致,注释分类置信度阈值取0.7时注释获得的物种组成、OTU组成和取0.8及以上时注释获得的有较大差异。3)在OTU聚类序列相似度阈值0.999、注释分类置信度阈值0.9时,多序列数据注释所得鱼类物种数、OTU数最多、物种注释正确率最高(达81.49%),分别比单序列数据的多7%、215%和高5%。在具体eDNA测序数据的分析和注释中,可通过建立完善本地参考数据库、优化OTU聚类序列相似度和物种注释分类置信度(序列一致性和序列覆盖度)取值、增加目标数据的丰富度来提高注释结果的准确性,但受制于物种注释算法的局限性,物种注释错误和注释遗漏的问题可能将长期存在,物种注释正确率通常低于85%(基于COI基因的eDNA监测)。

  • 不同气味对大鼠尿液蛋白质组的影响

    分类: 生物学 >> 生物化学 提交时间: 2024-01-20

    摘要: 大鼠在闻气味时,其尿液蛋白质组是否有相应的变化呢?闻不同气味产生的变化会不同吗?本研究通过对6只大鼠闻香油、风油精3天后,第3天、第4天的尿液样本进行采集,并使用LC-MS/MS技术对样本进行成组及单只前后对比分析。同时将已鉴定到的差异蛋白与同年龄段大鼠生长发育产生的差异蛋白进行比较,以排除生长发育对本实验结果造成的影响。实验结果表明,将香油组Day0和Day4的尿蛋白质组相比较,经过筛选可以鉴定到143个差异蛋白,随机产生的差异蛋白平均为7.32个,至少有94.88%的差异蛋白不是随机产生的。经成组及单只前后比较分析,同一气味呈现出较为一致的变化,在香油组鉴定到了与嗅觉产生相关的低密度脂蛋白受体相关蛋白2、COPD的生物标志物胎球蛋白B等差异蛋白,同时在风油精组鉴定到子宫球蛋白、三叶草因子3、粘蛋白2等变化显著且与嗅觉产生相关的差异蛋白。值得一提的是,我们在风油精组再次鉴定到了气味结合蛋白2A,同时存在于4只大鼠单只前后比较产生的差异蛋白中,这与电子烟模型呈现的结果一致。本研究证明,气味会对大鼠的尿液蛋白质组产生影响,不同气味对其的影响不同。这为探究嗅觉的生物学过程提供了新方法。

  • Spatiotemporal variations in ecosystem services and their trade-offs and synergies against the background of the gully control and land consolidation project on the Loess Plateau, China

    分类: 生物学 >> 生态学 提交时间: 2024-01-12 合作期刊: 《干旱区科学》

    摘要: Studying the spatiotemporal variations in ecosystem services and their interrelationships on the Loess Plateau against the background of the gully control and land consolidation (GCLC) project has significant implications for ecological protection and quality development of the Yellow River Basin. Therefore, in this study, we took Yan'an City, Shaanxi Province of China, as the study area, selected four typical ecosystem services, including soil conservation service, water yield service, carbon storage service, and habitat quality service, and quantitatively evaluated the spatiotemporal variation characteristics and trade-offs and synergies of ecosystem services from 2010 to 2018 using the Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) model. We also analysed the relationship between the GCLC project and regional ecosystem service changes in various regions (including 1 city, 2 districts, and 10 counties) of Yan'an City and proposed a coordinated development strategy between the GCLC project and the ecological environment. The results showed that, from 2010 to 2018, soil conservation service decreased by 7.76%, while the other three ecosystem services changed relatively little, with water yield service increasing by 0.56% and carbon storage service and habitat quality service decreasing by 0.16% and 0.14%, respectively. The ecological environment of Yan'an City developed in a balanced way between 2010 and 2018, and the four ecosystem services showed synergistic relationships, among which the synergistic relationships between soil conservation service and water yield service and between carbon storage service and habitat quality service were significant. The GCLC project had a negative impact on the ecosystem services of Yan'an City, and the impact on carbon storage service was more significant. This study provides a theoretical basis for the scientific evaluation of the ecological benefits of the GCLC project and the realization of a win-win situation between food security and ecological security.

  • Response of ecosystem carbon storage to land use change from 1985 to 2050 in the Ningxia Section of Yellow River Basin, China

    分类: 生物学 >> 生态学 提交时间: 2024-01-12 合作期刊: 《干旱区科学》

    摘要: Regional sustainable development necessitates a holistic understanding of spatiotemporal variations in ecosystem carbon storage (ECS), particularly in ecologically sensitive areas with arid and semi-arid climate. In this study, we calculated the ECS in the Ningxia Section of Yellow River Basin, China from 1985 to 2020 using the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model based on land use data. We further predicted the spatial distribution of ECS in 2050 under four land use scenarios: natural development scenario (NDS), ecological protection scenario (EPS), cultivated land protection scenario (CPS), and urban development scenario (UDS) using the patch-generating land use simulation (PLUS) model, and quantified the influences of natural and human factors on the spatial differentiation of ECS using the geographical detector (Geodetector). Results showed that the total ECS of the study area initially increased from 1985 until reaching a peak at 402.36106 t in 2010, followed by a decreasing trend to 2050. The spatial distribution of ECS was characterized by high values in the eastern and southern parts of the study area, and low values in the western and northern parts. Between 1985 and 2020, land use changes occurred mainly through the expansion of cultivated land, woodland, and construction land at the expense of unused land. The total ECS in 2050 under different land use scenarios (ranked as EPS>CPS>NDS>UDS) would be lower than that in 2020. Nighttime light was the largest contributor to the spatial differentiation of ECS, with soil type and annual mean temperature being the major natural driving factors. Findings of this study could provide guidance on the ecological construction and high-quality development in arid and semi-arid areas.

  • Spatiotemporal changes of gross primary productivity and its response to drought in the Mongolian Plateau under climate change

    分类: 生物学 >> 生态学 提交时间: 2024-01-12 合作期刊: 《干旱区科学》

    摘要: Gross primary productivity (GPP) of vegetation is an important constituent of the terrestrial carbon sinks and is significantly influenced by drought. Understanding the impact of droughts on different types of vegetation GPP provides insight into the spatiotemporal variation of terrestrial carbon sinks, aiding efforts to mitigate the detrimental effects of climate change. In this study, we utilized the precipitation and temperature data from the Climatic Research Unit, the standardized precipitation evapotranspiration index (SPEI), the standardized precipitation index (SPI), and the simulated vegetation GPP using the eddy covariance-light use efficiency (EC-LUE) model to analyze the spatiotemporal change of GPP and its response to different drought indices in the Mongolian Plateau during 19822018. The main findings indicated that vegetation GPP decreased in 50.53% of the plateau, mainly in its northern and northeastern parts, while it increased in the remaining 49.47% area. Specifically, meadow steppe (78.92%) and deciduous forest (79.46%) witnessed a significant decrease in vegetation GPP, while alpine steppe (75.08%), cropland (76.27%), and sandy vegetation (87.88%) recovered well. Warming aridification areas accounted for 71.39% of the affected areas, while 28.53% of the areas underwent severe aridification, mainly located in the south and central regions. Notably, the warming aridification areas of desert steppe (92.68%) and sandy vegetation (90.24%) were significant. Climate warming was found to amplify the sensitivity of coniferous forest, deciduous forest, meadow steppe, and alpine steppe GPP to drought. Additionally, the drought sensitivity of vegetation GPP in the Mongolian Plateau gradually decreased as altitude increased. The cumulative effect of drought on vegetation GPP persisted for 3.008.00 months. The findings of this study will improve the understanding of how drought influences vegetation in arid and semi-arid areas.

  • Regulation effects of water and nitrogen on yield, water, and nitrogen use efficiency of wolfberry

    分类: 生物学 >> 植物学 提交时间: 2024-01-12 合作期刊: 《干旱区科学》

    摘要: Wolfberry (Lycium barbarum L.) is important for health care and ecological protection. However, it faces problems of low productivity and resource utilization during planting. Exploring reasonable models for water and nitrogen management is important for solving these problems. Based on field trials in 2021 and 2022, this study analyzed the effects of controlling soil water and nitrogen application levels on wolfberry height, stem diameter, crown width, yield, and water (WUE) and nitrogen use efficiency (NUE). The upper and lower limits of soil water were controlled by the percentage of soil water content to field water capacity (f), and four water levels, i.e., adequate irrigation (W0, 75%85% f), mild water deficit (W1, 65%75% f), moderate water deficit (W2, 55%65% f), and severe water deficit (W3, 45%55% f) were used, and three nitrogen application levels, i.e., no nitrogen (N0, 0 kg/hm2), low nitrogen (N1, 150 kg/hm2), medium nitrogen (N2, 300 kg/hm2), and high nitrogen (N3, 450 kg/hm2) were implied. The results showed that irrigation and nitrogen application significantly affected plant height, stem diameter, and crown width of wolfberry at different growth stages (P<0.01), and their maximum values were observed in W1N2, W0N2, and W1N3 treatments. Dry weight per plant and yield of wolfberry first increased and then decreased with increasing nitrogen application under the same water treatment. Dry weight per hundred grains and dry weight percentage increased with increasing nitrogen application under W0 treatment. However, under other water treatments, the values first increased and then decreased with increasing nitrogen application. Yield and its component of wolfberry first increased and then decreased as water deficit increased under the same nitrogen treatment. Irrigation water use efficiency (IWUE, 8.46 kg/(hm2mm)), WUE (6.83 kg/(hm2mm)), partial factor productivity of nitrogen (PFPN, 2.56 kg/kg), and NUE (14.29 kg/kg) reached their highest values in W2N2, W1N2, W1N2, and W1N1 treatments. Results of principal component analysis (PCA) showed that yield, WUE, and NUE were better in W1N2 treatment, making it a suitable water and nitrogen management mode for the irrigation area of the Yellow River in the Gansu Province, China and similar planting areas.

    摘要: 为探究湘西石漠化区湿地松-马褂木人工混交林林分结构及土壤理化性质,该研究以湘西石漠化地区湿地松-马褂木人工针阔混交林为对象,利用植物群落学分析和野外取样检测的方法,分析林分结构和土壤理化性质,运用Winklemass 1.0计算林分空间结构参数,并用三维离散随机变量分析了优势种的空间分布格局。结果表明:(1)林分内DBH≥2 cm的林木有897 plants·hm-2,隶属于15科16属。主林层为湿地松,平均胸径32.3 cm,重要值为44.2%;次林层为阔叶树,中幼龄林木居多,其中樟树、马褂木为优势树种,重要值分别为17.1%、13.2%,此外还存在较多处于劣势生态位的天然更新种。(2)林木的水平分布格局偏向于随机分布( ̅=0.503);林分整体趋向于中庸偏劣势过渡的态势( ̅=0.505);种间隔离程度较高( ̅=0.689),林木混交状况良好。空间结构参数的三维离散随机变量表明,湿地松87.3%为优势和亚优势,马褂木41.7%为亚优势、26.9%为中庸态势,樟树23.5%为中庸态势、56.8%为劣势和绝对劣势。(3)林分土壤pH值趋于中性;与撂荒地相比,林分土壤的容重、持水量、孔隙度、有机碳、全钾、全氮、全磷等因子均明显改善,但整体而言,林分土壤仍然较为贫瘠,局部土壤紧实,保水能力差。综上表明,湿地松、马褂木做为先锋树种生长43年后,林分有向异龄林、强度混交林演替的趋势。但林分内中幼龄阔叶树株数占比较大,近熟林出现断层,老龄针叶树占据优势生态区位,需抽针补阔、间针育阔,择伐劣势木,促使林分向阳生性阔叶树为主、中生性和耐阴性阔叶树为次的林分结构演替。该研究结果为该地区的植被恢复、人工林结构优化和土壤改良提供理论依据。
