为探讨长吻海蛇（Hydrophis platurus）的宏观及微观形态特征，运用经典分类及扫描电镜观察方法，对相关标本的形态特征及鳞片微皮纹结构进行观察，结果表明：标本深色的背面与浅色的腹面具有清晰的分界，吻部明显突出，背、腹部鳞片的形状和大小无明显分别；背部鳞片显微皮纹结构表现为多个耳状结构沿身体纵轴方向交错排列，整个视野呈现为波纹状，耳状结构之间为较深的沟槽，耳状结构侧面布满小孔。标本形态结构符合长吻海蛇形态特征，其鳞片显微皮纹结构与同属眼镜蛇科（Elapidae）的陆上种类，如舟山眼镜蛇（Naja atra）、广西华珊瑚蛇（Sinomicrurus peinani）明显属于不同模式。长吻海蛇鳞片显微皮纹结构表现出显著的水生生活适应特征，此结构特征有利于长吻海蛇在游泳时减少阻力，其沟槽和小孔有利于对海水截留。研究结果认为，蛇类鳞片显微皮纹结构具有明确的分类学意义，但鳞片超微结构差异可能不适合用于推断蛇类系统进化关系。

青头潜鸭(Aythya baeri),东亚鸟种,曾广泛分布于从东北亚到东南亚并印度次大陆的广大地区[1],因其数量明显下降于20世纪90年代中期被视为易危物种(VU)[2],2008年被提升为濒危物种(EN)、2012年再升至极危物种(CR),“因其数量骤降”[3]。

目前黑龙江东北虎林园有东北虎1 000多只,每天会排出大量的粪便,之前仅将虎粪作为垃圾处理,耗费大量的人力、物力和财力,而且还存在处理不及时造成对水源、空气、土壤等污染的问题。本研究通过系统比较野生东北虎和人工圈养东北虎粪便的矿物质含量,分析不同饲喂条件下人工圈养东北虎虎粪的矿物质含量和营养组成,在充分认识虎粪的环境污染问题的基础上,探讨虎粪的有效利用问题,提出了虎粪可作为沼气池发酵原料和有机肥料等潜在的利用途径,为改善和美化东北虎林园的环境,同时为开发虎粪资源,变废为宝提供了新的思路。

针对5种典型单层球面网壳结构型式（联方型、施威德勒型、凯威特型、三向格子型和短程线型）,本文采用基于离散变量的序列两级截面优化算法对一百个不同跨度（30m60m）、不同矢高（1/31/7）的网壳进行截面优化设计,在截面优化设计结果中提取选型所需的优秀样本,一个优秀样本由3部分组成:跨度,矢跨比和该跨度、矢跨比下用钢量最少的网壳结构类型;然后利用BP人工神经网络对复杂非线性映射关系的模拟能力建立网壳跨度、矢跨比与用钢量最少的网壳型式之间的映射关系,避免了结构选型优化的多维、多重非线性模型的求解困难,通过截面优化简便地实现了网壳结构的选型优化。

本研究主要目的是在面對全球化趨勢影響之下，企圖以統整課程的方式將全球化課程融入國小社會學習領域課程之中。因此，本文首先由全球化趨勢與反全球化運動的背景與發展脈絡加以探討；其次分析全球化課程的核心概念及發展，並試圖以一則國小六年級全球化課程融入社會領域的實施歷程為例，提出分析與自我反省；最後探討課程設計與實施的成效及所面臨之問題。 本研究係由一名教育大學教授和現職國小教師協同完成，以行動研究的方式探討國小全球化課程融入社會領域教學之歷程，研究者以觀察、訪談、文件蒐集、省思札記等方式，從中蒐集相關文件資料，並進行資料的整理及分析。希望建構本土的全球化課程作為教育人員與課程編制者發展與統整課程之參考。 This study attempted to design a workable globalizational curriculum which was integrated with social studies at one elementary school. For this purpose, the researchers reviewed the research literature about the development and content of globalization, the relationship between globalization and anti-globalization, and further explored the concepts of global education and the curriculum of globalization. Action research method was adopted in this study. The research data were collected by ways of participant observation, interviews, collection of documents and reflection notes. The researchers had found some problems from the natural teaching situation at the first cycle. Then, we evaluated the teaching strategy and made adjustment at the next cycle. Conclusions and implementation were offered which may provide a basis for further study on the curriculum of globalization in Taiwan.

通过对7只不同年龄♂♀体大鸨生殖系统的形态结构解剖发现:大鸨雄性生殖系统由睾丸、附睾、输精管和交配器组成,无真正的阴茎,而具有阴茎体。睾丸一对,黑色、长形、豆状,右侧在前,左侧睾丸略大于右侧。大鸨睾丸从孵化出壳到性成熟无颜色变化,只是体积和重量增长。附睾在幼年时不明显,而在成体发情期时显著,呈前端较大的纺锤形。输精管外观为半透明、黑色弯曲的线状,沿输尿管向后延伸至泄殖腔壁形成突起,即输精管乳头;雌性生殖系统由卵巢和输卵管组成。卵巢和输卵管仅左侧正常发育,右侧输卵管退化为—短白色盲管。左卵巢因卵泡发育而呈葡萄串状。左输卵管在性未成熟时为一直形细管,性发育成熟后有较多弯曲,管径也增大,可分为漏斗部、壶腹部、峡部、子宫和阴道5部分。

归纳了大兴安岭林区发展野生动物养殖业的有利条件,对目前野生动物养殖中存在的种兽引进、饲料、抗病力、饲养管理等方面的问题进行了深入剖析,并提出种源本土化、饲料开发与供应、现代技术的推广应用、种群遗传管理、种质基因保存和产品精深加工等方面的对策。

中国幅员辽阔,从西北到东南跨寒、温、热等不同气候带。从生境类型上分,有多种森林、各类湿地、草原和沙漠等。复杂多变的生境孕育了十分丰富的鸟类资源。其中有一个比较特别的类群,即号鸟形目鸟类,俗称“猫头鹰”,它们是一类夜行性猛禽。

高峰鸟类保护环志站地处大、小兴安岭之间的嫩江河谷东岸,松嫩平原北部。特殊的地理位置使这里成为候鸟经松嫩平原迁徙途中重要的停歇地和食物补给站。自1998年开展环志以来,截止2006年12月末,在该地区发现鸟类215种,隶属15目36科,环志鸟类165种184 273只,其中,仅燕雀就环志13 174只,是高峰鸟类保护环志站环志数量较多的种类,占环志总数的7.1%。环志研究结果发现,在高峰林区春季迁徙高峰期基本在5月1日;秋季迁徙高峰期基本在9月24日。回收信息表明,燕雀迁徙距离较远,开展燕雀的环志研究,对探索鸟类迁徙规律、物种保护和野生动物疫源疫病监测等具有十分重要的意义。

黑龙江省松嫩平原是多种鸟类南北迁徙的主要途径和停歇地之一,有80余种鸟类迁徙中途经此地。结合全国陆生野生资源的调查,我们于1998年45月在松嫩平原的北缘嫩江县高峰林区,对当地春季迁徙的鸟类进行了观察,为在此地建立鸟类监测及环志站提供资料依据。

2006年,黑龙江东北虎林园的东北虎人工饲养种群超过700只,维持其生存的费用巨大,虎林园的管理策略研究应进一步加强。本文从服务管理、营销管理、人力资源管理、科普教育管理、基建管理五个方面进行了探讨。

又黑又胖的“黑瞎子”黑熊全身长满黑毛,加上它眼神儿有点差,所以东北一带又管它叫“黑瞎子”。其实,它并不是什么也看不见的瞎子,在森林里捕食避敌穿来跑去还相当灵活呢。在动物分类学上它隶属于食肉目、熊科,有的地方又叫它狗熊、狗驼子。

用扫描电子显微镜对莺亚科16种鸟羽的显微结构进行了研究。结果表明:各种属羽的显微结构特征都是恒定的,其间存在着一定的差异。可以通过羽的显微结构来比较鉴别相近似的种类,由此为莺亚科的系统分类提供新的依据。

大鸨（Otis tqrda）,俗名地鵏（bǔ）、老鵏,是亚洲地区体重最大的鸟类,成年雄性最重可达15公斤以上。其头颈部灰色,背部棕色,腹部白色,脚绿灰色,雄性喉部两侧长有白色的长而纤细的羽毛,酷似胡须。雌性体重较小,一般在48公斤之间,无须。由于雄性和雌性外部形态差异较大,因此在民间常被误认为是两种鸟,把雄鸟称为“羊须鵏”,把雌鸟称为“石鵏”。

喜鹊（Pica pica）属雀形目鸦科, 是人们熟悉和喜爱的一种鸟类,自古以来被人们认为是吉祥的象征。许多地方留传着"喜鹊叫喳喳,喜事到我家"的民谣。关于喜鹊的行为还有许多鲜为人知的趣事。喜鹊爱吃荤喜鹊是一种杂食性鸟类,食物主要以各种昆虫为主,如蝗虫、甲虫、蜂类等昆虫及其幼虫,也吃谷粒、豆子、植物种子和嫩的茎叶。但很少有人知道喜鹊还吃一些动物的尸体,捕猎一

特种经济动物养殖业近年来发展很快,特种经济动物的种类也越来越多,从利用价值上可以将特种经济动物分为药用动物、裘皮（革）用动物、肉用动物和观赏动物等几大类。狭义而言,我国目前饲养的特种经济动物主要指国家林业局在2003年发布的可以从事商业性经营利用、驯养繁殖技术成熟的54种陆生野生

喜鹊（Pica pica）属雀形目鸦科,是人们熟悉和喜爱的一种鸟类,自古以来被人们认为是吉祥的象征。许多地方留传着“喜鹊叫喳喳,喜事到我家”的民谣。可是喜鹊有趣的婚姻却鲜为人知。喜鹊是一夫一妻制,每年繁殖一次,春天开始繁殖,时间从南向北依次略微延迟。 奇特的聘礼 每年的繁殖季节一到,雄喜鹊会给雌喜鹊献上独特的礼物。这礼物就是一

Objective: To investigate the difference of the attention bias of the resilience level of professional technicians in hospital to negative information. Methods: A total of 383 professional technicians of logistics administrative posts in a third-level military hospital were selected and divided into high and low groups according to their scores on the resilience scale (the top 27% of the participants were in the high resilience group, and the bottom 27% were in the low resilience group). There were 22 participants in each of the high and low resilience groups that met the requirements. The attention bias test was conducted on the professional technicians in the high and low resilience groups using the Dot-probe Paradigm. A mixed experimental design of 2 (group: low resilience group, high resilience group) x2 (stimulus clues: negative stimulus, neutral stimulus) was adopted. The dependent variables were correct rate and reaction time. Results: The interaction between the response group and the stimulus cue was statistically significant (P<0.05), the response time of negative stimulus in low resilience group was lower than that of neutral stimulus. The main effect of the cue condition was statistically significant in both groups (P<0.05), the correct rate of negative stimulus was lower than that of neutral stimulus. Conclusion: This study shows that the professional technicians in the high resilience group do not have obvious attention bias to negative information, while the professional technicians in the low resilience group have obvious attention bias to negative emotional information.

The spleen is the largest lymphoid organ of the body, which participates in the regulation of metabolic balance. High altitude hypoxia environment can affect lipid metabolism in spleen tissue, but the key mechanism of lipid metabolism is still unclear. We aimed to use lipidomic analysis to study the effect of high altitude hypoxia on lipid metabolism in mouse spleen tissue. C57BL/6 mice were placed at an altitude of 4 200 m and 400 m, respectively, and after 30 days the spleen tissues were harvested and lipidomic analysis was performed using an ultra-high performance liquid chromatography-Orbitrap mass spectrometry system. Under the high altitude hypoxia environment, the spleen index of mice and the white pulp decreased, and the germinal center expanded with other pathological changes. The results of lipidomic analysis showed that a total of 41 lipid subclasses and 2 473 lipid molecules were identified, and triacylglycerides (TGs) and phosphatidylcholines (PCs) were the two most identified lipid molecules. Using univariate and multivariate analysis, 44 differentially expressed lipid molecules were identified, which were mainly concentrated in phospholipid metabolism. Subsequently, RT-qPCR was performed on the key enzymes hes in the phospholipid metabolic pathway, and it was found that the mRNA expression levels were different (P<0.05). It suggested that high altitude hypoxia environment mainly affects the phospholipid metabolism of mouse spleen tissue via reducing the contents of PC and phosphatidic acid (PA), promoting their conversion to phosphatidylethanolamine (PE) and cardiolipin (CL) and facilitating the PE production via the CDP-Etn pathway. This study provides a new experimental basis for the abnormal metabolism of phospholipids in spleen tissue under high altitude hypoxia environment. [ABSTRACT FROM AUTHOR]
