白腹锦鸡(Chrysolophus amherstiae)的夜栖地选择

2005年4月～2006年9月,结合无线电遥测技术,采用系统搜索法和繁殖期跟踪法对四川石棉县栗子坪自然保护区白腹锦鸡的夜栖地选择进行了研究。共发现24个夜栖地。以夜栖树为中心做r=7.5m大样方,随机在其中做4个1m×1m和4个0.5m×0.5m小样方,测量乔木、灌木和草本植物的各项参数;做128个非活动区对照样方和258个日栖地样方,分别随机选取等量样方与夜栖地样方相比较。结果表明:白腹锦鸡夜栖地多在针阔混交林和针叶林中,栖树以针叶树为主,繁殖期内成对个体同树共栖的栖位距离较近,栖枝雄高雌低。影响白腹锦鸡夜栖地选择的主要因素依次为:地形、栖树、隐蔽条件和遮蔽特征。与对照样方相比,白腹锦鸡夜栖地选择较矮而疏的乔木和少量倒木的环境;与日栖地样方相比,选择较矮、疏和较低盖度灌木草本植物的环境,有一定的空间分离。     

海南原鸡繁殖期夜栖地的选择

原鸡Gallus gallus在繁殖期的日常活动趋向于以夜栖地为中心,因此夜栖地的研究对原鸡的繁殖和保育具有重要意义.2008年2～5月在海南大田自然保护区,采用野外观察和样方调查相结合的方法,对原鸡的夜栖地利用进行了研究,共记录到15个夜栖地.结果表明: 1) 原鸡在繁殖期多结成2～6只(3.3±1.5, n=13)的繁殖群,在同一棵树或邻近几棵树上集群夜栖; 2) 落叶季雨林和灌丛草地是原鸡繁殖期夜栖的主要植被类型; 3)原鸡多以小刺竹Bambusa bambos作为夜栖树,占53.3%,其次是厚皮树Lannea coromandelica,占20.0%; 4)原鸡倾向于选择灌木生长茂密、地面草本稀疏的生境作为夜栖地,并栖息在胸径均值为8.4 cm±3.5 cm的乔木或灌木的枝条上,栖枝均高为4.4 m±0.8 m; 5)主成分分析表明,影响原鸡夜栖地选择的主要因子依次为:栖树高、栖枝高度、栖树胸径、栖枝层盖度、草本层盖度、栖枝下方盖度和栖枝上方盖度.据此分析认为:繁殖期原鸡警惕性高,夜栖地多选择易于隐蔽和转移的生境.     

再引入黑颈长尾雉夜栖行为与夜栖地选择

2003年4月～2005年3月,通过野外观察、无线电遥测和样方调查,对广西岑王老山自然保护区再引入黑颈长尾雉的夜柄行为和夜柄地进行了研究.共观察记录到10个夜栖地,黑颈长尾雉夜间主要在树上栖息,偶尔在地上柄息,在针叶林为独栖(1只/树),在阔叶林独柄或者2～3只/树.黑颈长尾雉夜柄地选择受到柄树的高度、大小,灌术、乔木、草本层的盖度,水源距离及栖枝高度等因素的影响.黑颈长尾雉夜栖地的栖树具有一定的高度(雌:4.96±1.39 m,雄:5.52±1.95 m)和胸围大小(雌:21.4±8.29 cm,雄:23.50±8.39 cm);乔木层(78.00%±8.23%)和灌木层(44.50%±29.67%)盖度较大,草本层盖度较低的环境作为夜栖地;与水源具有一定的距离(348.50±308.30)m;夜栖地的坡度(44.80.±14.73.)和栖枝的高度(2.40±0.74 m).     

云南蒙自钳嘴鹳夜栖地利用及夜栖树选择

动物对夜栖地选择的灵活程度是其分布和扩散的重要因素之一。钳嘴鹳(Anastomus oscitans)为中国新分布种,要了解其扩散趋势,掌握其夜栖地需求至关重要。2015年11月至2018年7月在云南蒙自坝区,使用卫星跟踪技术对6只钳嘴鹳进行了夜栖地利用和夜栖树选择研究,结果表明:(1)钳嘴鹳可以在多种生境中夜栖,包括林地、沼泽、岛屿等。从群体水平上分析,钳嘴鹳主要夜栖于沼泽中,利用率为(51.19±12.34)%,其次为林地(31.55±11.34)%和岛屿(17.26±5.70)%;从个体水平上来看,不同钳嘴鹳的夜栖地利用方式差异较大,其中4只主要利用沼泽,而另外2只主要利用林地;(2)随机森林分析表明:影响钳嘴鹳夜栖树选择的首要因子为距觅食地距离,其次为树高、地径和最低枝高度,而人为干扰因子的影响较弱。综合来看,钳嘴鹳对夜栖地类型以及夜栖树均表现出了极强的适应性和可塑性,这可能是其能够快速扩散的重要原因之一。同时也表明夜栖树并不能成为一个有力的限制因子,钳嘴鹳有可能继续向国内的南方湿地区扩散。     

陕西黄龙山林区褐马鸡春季夜栖地选择

2006年4～6月,在陕西黄龙山林区,对褐马鸡(Crossoptilon mantchuricum)春季夜栖地的选择进行了研究.共记录到22个夜栖地,以夜栖树为中心做一个10 m×10 m样方,测定夜栖地海拔、坡向、坡度、坡位、地貌特征、夜栖树高度和胸径、乔木层盖度、乔木的数量、灌木层盖度、草本盖度、水源距离、人为干扰距离、林缘距离、栖枝高度和栖位上盖度等参数;通过9条样带测定54个随机样方,除栖枝高度和栖位上盖度外,指标相同.结果表明,褐马鸡春季夜栖地多偏向以坡度较大、山坡和山脊、接近水源、远离林边、人为干扰距离较远、乔木盖度和密度较大、栖树胸径较大、灌木层盖度和草本层盖度较小为主要特征的地方.主成分分析表明,前5个特征值的累积贡献率达到72.746%,可以较好地反映褐马鸡春季夜栖地生境特征.根据载荷系数绝对值大小,将褐马鸡春季夜栖地生境选择影响因子分别命名为地形和林下植被因子、气象因子、稳定性因子和水因子.影响褐马鸡夜栖地选择的关键因素是安全、舒适和栖息地转换的方便程度.     

红喉雉鹑繁殖季的夜栖行为与夜栖地选择

红喉雉鹑（Tetraophasisobscurus）是中国特有种,国家一级重点保护野生动物,研究其繁殖季的夜栖地选择,能丰富该物种的基础资料,理解其生存策略,为该物种的保护和深入研究提供科学依据。2021年和2022年的3～7月,采用跟踪观察和系统搜索法,对四川王朗国家级自然保护区繁殖期红喉雉鹑的夜栖行为和夜栖地选择进行了调查,共记录夜栖地样方34个。采用卡方检验、配对样本T检验、Mann-WhitneyU检验和逻辑斯蒂回归模型方法对数据进行分析。红喉雉鹑主要夜栖于方枝柏（Sabina saltuaria）等针叶树,常见1只单独夜栖或2只共同夜栖,未见有集群夜栖;夜栖树通常位于上坡位,距离林缘和最近乔木较近,具有较大的胸径和郁闭度,栖枝距离地面高度6.6 m左右,栖枝长度约1.66m;夜栖地具有较大的坡度和落叶盖度,而灌木盖度较小。安全因素（夜栖树胸径、坡度）和食物因素（落叶盖度）是红喉雉鹑选择夜栖地的最关键因素。     

四川雉鹑的冬季夜栖地选择

四川雉鹑(Tetraophasis szechenyii)是中国特有物种,国家Ⅰ级重点保护野生动物,对其冬季夜栖地选择的了解,有助于理解物种的生存策略,为物种保护提供参考。利用徒步跟踪和无线电遥测的方法,我们于2006年9月到2007年4月在四川省雅江县帕姆岭进行了野外研究。采用卡方检验、配对样本t检验和二元逻辑斯缔回归等方法对数据进行分析。结果发现:(1)四川雉鹑利用鳞皮冷杉(Abies squamata)和大果红杉(Larix potaninii var.macrocarpa)两种树夜栖,卡方检验分析发现四川雉鹑对这两树种没有明显的选择偏好(χ2=0.745,df=1,P=0.388);(2)夜栖树的胸径为(25.8±1.3)cm,夜栖枝条离地高度为(6.3±0.3)m,直径为(3.3±0.1)cm;(3)与对照样地相比,夜栖地生境一般靠近林缘,乔木的平均胸径大、林下盖度小、倒木数量多,夜栖树胸径大、最近乔木胸径大和最近乔木距离远;(4)逻辑斯缔回归分析表明:夜栖树第一枝距地面高为冬季四川雉鹑夜栖地选择的关键因子;倒木数量、平均乔木胸径、最近林缘距离为次关键因子,该模型对夜栖地的预测正确率为80.9%。冬季四川雉鹑选择夜栖地是安全、能量和地点转移三个因素综合作用的结果,在不同的环境下,同一物种对环境会有不同的适应策略。     

城市绿地中鹊鸲繁殖期和非繁殖期夜栖地选择

夜栖地是昼行性鸟类夜间重要的栖息场所,鸟类对夜栖地的选择有明显偏好性。随着城市化加剧,城市绿地逐步成为城市鸟类生存的庇护所,如何适应城市环境的干扰并安全夜栖于城市绿地中是鸟类在不同生活史阶段均需面临的问题。为探讨城市绿地中鸟类的夜栖地选择,本研究于2014年3月至2015年2月在广西宜州市区龙江河畔,采用系统调查法对鹊鸲(Copsychus saularis)繁殖期和非繁殖期的夜栖树种、夜栖地特征的17个生态因子进行了比较。结果显示:鹊鸲共选择15种夜栖树,繁殖期和非繁殖期的树种选择差异极显著,2个时期均选择5种夜栖树,其中利用频次较高的是桂花(Osmanthus fragrans)、杧果(Mangifera indica)和佛肚竹(Bambusa ventricosa)。主成分分析发现,繁殖期和非繁殖期夜栖地选择的主要因素均是栖树、栖枝隐蔽性以及周围安全性因素,其他栖枝、水源和食物因素次之,最后为干扰因素;其中,栖树和栖枝高度、乔木、草本和栖枝下方盖度等9个生态因子在2个时期间具有差异性。城市鹊鸲在生活史不同阶段选择最适夜栖地,体现出对强干扰城市生境的适应性。在未来城市绿化配置和建设中需增加具不同栖枝、树高和盖度特征的乔木树种,提高灌木和草本植被多样性,以满足不同鸟类对城市绿地中夜栖地的需求。     

鸟类夜栖地选择研究进展

夜栖地可以为鸟类提供安全、舒适、温暖的夜间栖息场所。昼行性鸟类夜间视觉能力较差,对夜栖环境中潜在的威胁感知程度较低,导致其夜栖时常常处于被动和危险的环境中。鸟类通过选择适宜的夜栖地,进而达到充分利用夜栖地空间资源的目的。本文从鸟类夜栖地选择的行为适应性以及保温性、食物因子和安全性(隐蔽性)等3个影响因素,对国内外鸟类夜栖地选择相关研究进行综述,为今后该领域的研究提供更多思路。     

贵州草海越冬黑颈鹤飞出飞回夜栖地行为节律初步观察

野生动物行为节律常常是其对环境变化的一种行为适应。黑颈鹤(Grus nigricollis)越冬期会利用固定夜栖地,形成每天早晨飞出觅食,傍晚飞回夜栖的固定行为模式。为探索这一固定行为模式在越冬不同时期的变化及其影响因素,利用瞬时扫描法对草海湿地全部7个固定夜栖地的黑颈鹤飞出和飞回夜栖地准确时间及飞出之前和飞回之后在夜栖地的行为节律进行了观察。并且保证越冬前期(11月9日至12月31日)、中期(1月1日至2月21)和后期(2月22日至3月31日)3个阶段的调查时间分别不低于15 d。结果表明,越冬不同时期黑颈鹤飞出夜栖地时间差异极显著(F=23.38,P0.01),飞回夜栖地时间存在显著性差异(F=3.51,P0.05)。整个越冬期,黑颈鹤飞出夜栖地时间在中期延后,而到后期则更为提前,越冬前期、中期和后期飞出夜栖地的平均时间分别为7:34时、7:40时和7:13时;而飞回夜栖地时间逐渐延后,平均时间由前期的17:12时,至中期的17:40时和后期的18:15时。黑颈鹤飞出夜栖地之前的行为在越冬前期、中期和后期差异极显著(F=1 768.25,df=12,P0.01),飞回夜栖地之后的行为在前期、中期和后期差异亦极显著(F=793.98,df=12,P0.01)。越冬前期、中期和后期,黑颈鹤飞出夜栖地之前的行为与飞回夜栖地之后的行为均差异极显著(前期F=2 723.16,df=6,P0.01;中期F=1 979.48,df=6,P0.01;后期F=5 098.18,df=6,P0.01)。黑颈鹤在飞出夜栖地前的80 min内,其行为以保养(34.32%)和休息(32.38%)为主;而飞回夜栖地后的90 min内,以觅食(43.04%)和休息(23.68%)为主。飞出时刻与日出时刻呈显著强相关(r=0.832,n=48,P0.01),飞回时刻与日落时刻呈弱相关(r=0.353,n=47,P0.01)。日出时间与黑颈鹤飞出夜栖地的时间的差值(Y1)受飞离时的空气湿度(W)影响,二者成反比,Y1=0.469﹣0.625W,P0.05。黑颈鹤飞回夜栖地时刻与日落时刻的差值(Y2)受当天平均温度(T)的影响较为显著,Y2=1.231﹣0.107T,P0.05,当天平均温度越高黑颈鹤飞回夜栖地时间越早,温度越低,黑颈鹤飞回夜栖地的时间越晚。研究结果对于进一步探讨黑颈鹤完整夜栖行为及其对干扰的适应性具有重要意义。     

Crystal structure, detonation performance, and thermal stability of a new polynitro cage compound: 2, 4, 6, 8, 10, 12, 13, 14, 15-nonanitro-2, 4, 6, 8, 10, 12, 13, 14, 15-nonaazaheptacyclo [5.5.1.13, 11. 15, 9] pentadecane

A new polynitro cage compound 2, 4, 6, 8, 10, 12, 13, 14, 15-nonanitro-2, 4, 6, 8, 10, 12, 13, 14, 15-nonaazaheptcyclo [5.5.1.1(3,11).1(5,9)] pentadecane (NNNAHP) was designed in the present work. Its molecular structure was optimized at the B3LYP/6-31 G(d,p) level of density functional theory (DFT) and crystal structure was predicted using the Compass and Dreiding force fields and refined by DFT GGA-RPBE method. The obtained crystal structure of NNNAHP belongs to the P-1 space group and the lattice parameters are a = 9.99 ?, b = 10.78 ?, c = 9.99 ?, α = 90.01°, β = 120.01°, γ = 90.00°, and Z = 2, respectively. Based on the optimized crystal structure, the band gap, density of state, thermodynamic properties, infrared spectrum, strain energy, detonation characteristics, and thermal stability were predicted. Calculation results show that NNNAHP has detonation properties close to those of CL-20 and is a high energy density compound with moderate stability.     

Relations of the Al,B, Ba,Br, Ca,Cl, Cu,Fe, K,Li, Mg,Mn, Na,P, S,Si, Sr,and Zn mass fractions to morphometric parameters in pediatric and nonhyperplastic young adult prostate glands

The variation with age of the 18 trace element mass fractions and some histological characteristics of intact prostate glands of 50 subjects aged 0–30 years was investigated by instrumental neutron activation analysis, inductively coupled plasma atomic emission spectrometry, and a quantitative morphometric analysis. Mean values ± standard error of the mean (M ± SΕΜ) for the mass fractions (in milligrams per kilogram wet tissue) of these trace elements in pre-puberty were: Al 28.5 ± 9.0, B 0.40 ± 0.11, Ba 1.48 ± 0.44, Br 10.5 ± 1.5, Ca 241 ± 30, Cl 3,203 ± 278, Cu 3.51 ± 0.89, Fe 33.7 ± 4.1, K 2,364 ± 145, Li 0.020 ± 0.004, Mg 153 ± 23, Mn 0.46 ± 0.06, Na 2,286 ± 130, P 1,391 ± 100, S 1,698 ± 132, Si 62 ± 11, Sr 0.38 ± 0.08, and Zn 27.6 ± 2.3. During puberty and postpuberty, when there is a significant increase in circulating androgens, the mean values were: Al 7.2 ± 1.4, B 0.21 ± 0.05, Ba 0.25 ± 0.06, Br 5.8 ± 1.0, Ca 433 ± 81, Cl 2,314 ± 201, Cu 1.77 ± 0.13, Fe 20.9 ± 1.6, K 2,585 ± 118, Li 0.0088 ± 0.0014, Mg 232 ± 27, Mn 0.34 ± 0.04, Na 1,875 ± 107, P 1,403 ± 98, S 1,673 ± 73, Si 22.2 ± 3.1, Sr 0.22 ± 0.03, and Zn 93.3 ± 8.9. Mean values (M ± SΕΜ) of percent volumes (%) of the stroma, epithelium and lumen in the prostate before puberty were 73.4 ± 2.6, 20.4 ± 1.7, and 4.45 ± 0.94, respectively, versus 46.5 ± 2.5, 38.5 ± 1.9, and 14.9 ± 1.2 during puberty and postpuberty. This work’s results confirm that the Zn mass fraction in prostate tissue is an androgen-dependent parameter. For the first time it has been demonstrated that the glandular lumen is a main pool of Ca, Mg, and Zn accumulation and that the stroma is a main pool of Al, B, Ba, Br, Cl, Cu, Fe, Mn, Na, and Si accumulation in the normal human prostate, for the age range 0–30 years. It was concluded that the Ca, Mg, and Zn binds tightly within the prostatic fluid, because the volume of glandular lumen reflects the volume of prostatic fluid.     

Simultaneous measurement of the trace elements Al, As, B, Be, Cd, Co, Cu, Fe, Li, Mn, Mo, Ni, Rb, Se, Sr, and Zn in human serum and their reference ranges by ICP-MS

The goal of this article was to establish reference ranges of the concentration of trace elements in human serum and to compare these results with those reported by other authors. We describe the sample preparation and measurement conditions that allow the rapid, precise, and accurate determination of Al, As, B, Be, Cd, Co, Cu, Fe, Li, Mn, Mo, Ni, Rb, Se, Sr, and Zn in human serum samples (n=110) by inductively coupled plasma-mass spectrometry (ICP-MS). Accuracy and precision were determined by analyzing three reconstituted reference serum samples by comparison with other methods and by the standard addition procedure. The advantages of the ICP-MS method include short time of analysis of the elements mentioned, low detection limit, high precision, and high accuracy. Disadventages include a high risk of contamination due to the presence of some of the elements of interest in the environment, the relatively delicate sample handling, and the high cost of the equipment.     

The Effect of Age and Gender on Al, B, Ba, Ca, Cu, Fe, K, Li, Mg, Mn, Na, P, S, Sr, V, and Zn Contents in Rib Bone of Healthy Humans

The effect of age and gender on major, minor, and trace element contents in the intact rib bone of 80 relatively healthy 15–55-year-old women and men was investigated. Contents or upper limit of contents of 16 chemical elements in the rib bone were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). Mean values (M?±?SΕΜ) for the mass fraction of Ba, Ca, Cu, Fe, K, Li, Mg, Na, P, S, Sr, and Zn (milligram per kilogram of dry bone) were as follows: 2.54?±?0.16, 171,400?±?4,050, 1.35?±?0.22, 140?±?11, 1,874?±?71, 0.049?±?0.011, 2,139?±?38, 5,378?±?88, 75,140?±?1,660, 1,881?±?51, 291?±?20, and 92.8?±?1.5, respectively. The upper limits of contents of Al, B, Mn, and V were <7.20, <0.65, <0.36, and <0.03, respectively. Statistically significant tendency for the Ca, Mg, and P content to decrease with age was found in the human rib bone, regardless of gender. The mass fraction of Fe in the male rib bone increases with age. It was shown that higher Ca, Mg, Na, P, and Sr mass fractions as well as lower Fe content were typical of female ribs as compared to those in male ribs.     

Distribution of N,P, K,Ca, Mg,S, Zn,Fe, Mn and Cu in groundnut

Summary Concentration of N, P, K, Ca, Mg and S in summer groundnut crop was higher than in kharif while Zn, Fe, Mn and Cu contents were higher in summer crop. Kernel's N, P and Zn; Leaflet's Ca and Mn; Stem's K and Fe; Root's S and Cu and Petiole's Mg contents were highest. Shell's N, P, K, Mg, S, Zn and Cu; Kernel's Ca, Fe and Mn contents were the least. N, P, K, S, Zn and Cu concentrations decreased linearly as the crop grew. Ca, Mg, Fe and Mn concentrations did not display any distinct pattern. Ca concentration was positively correlated with pod yield in both the seasons.     

Reference values for the concentrations of As,Cd, Co,Cr, Cu,Fe, I,Hg, Mn,Mo, Ni,Pb, Se,and Zn in selected human tissues and body fluids

This report attempts to formulate reference ranges of elemental concentrations for 15 trace elements in selected human tissues and body fluids. A set of samples consisting of whole blood, blood serum, urine, milk, liver, and hair were chosen and considered for 15 elements of biological significance: As, Cd, Co, Cr, Cu, F, Fe, I, Hg, Mn, Mo, Ni, Pb, Se, and Zn. The results represent wholly or partially data received from 40 countries of the global regions of Africa, Asia, Europe, North, South, and Central America, Australia, and New Zealand. This survey, even if qualitative, has been useful in demonstrating certain trends of trace-element scenarios around the world. It is of course recognized that both diet and environment exert a strong influence on the distribution pattern of several elements, such as As, Cd, Mn, Pb, Se, and Zn. A limited comparison of the available information on soil status of different countries reflected some interesting associations for elements, such as Mn and Zn. Importantly, this study revealed that only a few countries were in a position to identify a reasonable amount of data on samples requested for this project. Regretably, for a number of countries, any dependable data for even such essential elements as Cu, Fe, and Zn were not available. In view of the nutritional importance of many elements, the time is ripe for concerted efforts by intergovernmental agencies to initiate investigations or commission task forces/projects to generate reliable reference data for selected global regions, which sadly lack data of any kind at present.

Potential Compounds for Oral Cancer Treatment: Resveratrol,Nimbolide, Lovastatin,Bortezomib, Vorinostat,Berberine, Pterostilbene,Deguelin, Andrographolide,and Colchicine

Oral cancer is one of the main causes of cancer-related deaths in South-Asian countries. There are very limited treatment options available for oral cancer. Research endeavors focused on discovery and development of novel therapies for oral cancer, is necessary to control the ever rising oral cancer related mortalities. We mined the large pool of compounds from the publicly available compound databases, to identify potential therapeutic compounds for oral cancer. Over 84 million compounds were screened for the possible anti-cancer activity by custom build SVM classifier. The molecular targets of the predicted anti-cancer compounds were mined from reliable sources like experimental bioassays studies associated with the compound, and from protein-compound interaction databases. Therapeutic compounds from DrugBank, and a list of natural anti-cancer compounds derived from literature mining of published studies, were used for building partial least squares regression model. The regression model thus built, was used for the estimation of oral cancer specific weights based on the molecular targets. These weights were used to compute scores for screening the predicted anti-cancer compounds for their potential to treat oral cancer. The list of potential compounds was annotated with corresponding physicochemical properties, cancer specific bioactivity evidences, and literature evidences. In all, 288 compounds with the potential to treat oral cancer were identified in the current study. The majority of the compounds in this list are natural products, which are well-tolerated and have minimal side-effects compared to the synthetic counterparts. Some of the potential therapeutic compounds identified in the current study are resveratrol, nimbolide, lovastatin, bortezomib, vorinostat, berberine, pterostilbene, deguelin, andrographolide, and colchicine.
