ECOLOGICAL SERIES OF SOIL ANIMALS IN DARLIDAI MOUNTAIN

The ecological series of soil animals under the broad-leaved and pine mixed forest in Darlidai Mountainwas studied. Seven sample plots were selected according to different altitude gradients, which belong to different vegeta-tion types. By investigating and analyzing soil animals in every sample plot it is found that there are 45 groups and 1956individuals, which axe involved in 3 phylums, 7 classes, 16 orders, respectively. The altitude is a key factor which af-fects ecological series of soil animals. Both the groups and individuals of soil animals increase with altitude increasingunder certain conditions, which contrastes with ordinary cases, resulting from special micro-climate in studied area. Thegroups and individuls of soil animals are the most under the broad-leaved and pine forest on the top of the mountain, andthe least under Picea-Abies forest in the foot of the mountain.     

Heat-shock protein 70 expression in shrimp Fenneropenaeus chinensis during thermal and immune-challenged stress

Using western immunoblotting, we obtained heat-shock protein 70 (HSP70) induction data and distribution in different tissues from shrimp Fenneropenaeus chinensis during thermal and immune-challenged stresses. This is probably the first report of the effects of various stressors on the expression of HSP70 in shrimp.HSP70 was prominently induced in hepatopancreas and gills, but not in muscle, eyestalk and hemolymph, when the shrimp were exposed to heat shock and Vibrio anguillavium-challenged stresses. Cold shock and WSSV treatment had no significant effects on the levels of HSP70 expression in all tissues examined. HSP70 induction was greatest after 2 h exposure to heat shock stress, which was elevated after acute heat shock exposure of 10℃ above ambient temperature.     

Final report of IGCP Project 410 （1997-2002）——The Great Ordovician Biodiversification Event Department of Earth and Planetary Sciences, Macquarie University, North Ryde, NSW 2109, Australia. E-mail： bwebby@laurel.ocs.mq.edu.au

In 1997, IGCP Project No. 410 was established to appraise known records of Ordovician biotas, in order to evaluate one of the greatest-ever diversifications of life on Earth, between 489 and 443 million years ago. Data collection and analysis of biodiversity were coordinated through seven regional teams, and a global“clade” team.

YTI-A视频时码插入器的研制

在人造卫星观测的ＣＣＤ图象记录中，为方便图象保存，查阅及图象处理，将图象记录中的相关信息插入记录的图象中是十分重要的。ＹＴＩ－Ａ视频时码插入器正是为此应用而设计。本仪器内有一个可自动与后面板输入秒同步到１μｓ的数字钟。记录日期包括年月日，时刻记录精度为１０μｓ，望远镜指向（Ａ，ｈ）的记录精度为１″。这些信息全部以二种格式被插入记录的图象中可供图象处理时查阅和快速读出。文中叙述了仪器原理及应用     

大海龟——为了生存的挣扎

如果你正在搜集热心的人是如何动员起来帮助一个物种的故事,那么全球范围的拯救大海龟行动将是一个很好的例子。如果不是世界各地人们的积极参与,能在海洋中游过数千千米的这些古老生物,虽然寿命超过人类,但可能已经彻底灭绝了。
