日本东北大地震——大自然给人类上的又一课

作者介绍了2011年3月11日日本东北地区太平洋沿岸近海的M9.0特大地震的震后研究情况,日本列岛M8.0以上大地震发生的地球动力学背景、地理环境,大地震在东北太平洋沿岸地区、关东地区、东海道地区的活动历史以及对下一次东海地震发生时间的最新研究进展。最后总结了地震中长期预测的现状及相关基础研究应努力的方向,提出了在工程应用研究中应该避免的错误工作思路。     

Sea surface temperature east of Australia： A predictor of tropical cyclone frequency over the western North Pacific？

The relationship between sea surface temperature (SST) east of Australia and tropical cyclone frequency over the western North Pacific (WNPTCF) is analyzed by use of observation data.The WNPTCF from June to October is correlated negatively to spring SST east of Australia.When the spring SST is in the positive phase,a cyclonic circulation anomaly in the upper troposphere and an anticyclonic circulation anomaly in the lower troposphere prevail over the western North Pacific from June to October,concurrent with an anomalous atmospheric subsidence and an enlarged vertical zonal wind shear.These conditions are unfavorable for tropical cyclone genesis,and thus WNPTCF decreases.The negative phase of the spring SST east of Australia leads to more tropical cyclones over the western North Pacific.The spring SST east of Australia may give rise to simultaneous change in tropical atmospheric circulation via the teleconnection wave train,and then subsequently affect atmospheric circulation variation over the western North Pacific.     

西部开发背景下贵州红色题材影视创作的现实思考

在红色题材影视创作的书写系统中,贵州被加工成梦幻奇观、英雄神话的空间固然能够为受众提供某种程度上的观赏性消费满足,但是,决不应该让视听文本里的"西部空间"失去自治性、多样性的可能去受控于市场操作的过程;贵州不应是一个从现实中被抽离出来并放置到梦幻和神话表意系统中的、抽象的、空洞的符号,而应是一个建立在现实地理空间基础上的、具有区域特征和民族文化特色的、历史与现实相生的人文系统。

西北太平洋柔鱼资源丰度时空分布的GAM模型分析

根据1996~2001年我国在西北太平洋海域柔鱼生产统计及相关数据,利用GAM模型分析了表温、月份、经纬度等因子对柔鱼资源丰度CPUE的影响.研究认为,经纬度、月份和表温对CPUE时空分布都有较大的影响.160°E以西海域CPUE高,而165°E以东海域低,并主要集中在40°N~43°N海域.8~10月CPUE为最大.不同海域柔鱼分布的适宜表温不相同,150°E以西海域为13~18℃,150°E~165°E海域为14~18℃,165°E~180°E海域为11~14℃.     

Terrestrial isopods and myriapods in a forested scree slope: subterranean biodiversity,depth gradient and annual dynamics

Diversity, depth distribution and seasonal activity of isopods and myriapods were studied using subterranean traps buried in a forested limestone scree slope in the ?ierna Hora Mts, Western Carpathians, Slovakia, throughout the depth gradient from 5 to 95 cm. A total of five isopod, 13 diplopod and 11 chilopod species were identified. Most edaphic species strongly preferred the uppermost organic soil layers. Among the species captured, some represented rare stenoecous Carpathian endemics, namely the isopod Trichoniscus carpaticus, and diplopods Julus curvicornis and Leptoiulus mariae. Others were subterranean forms, partly adapted to hypogean conditions: the isopod Mesoniscus graniger, and diplopods Mecogonopodium carpathicum and Trachysphaera costata. The annual activity in the vast majority of the species ceased completely in winter, and was gradually relaunched in spring. In evaluating the age structure of two predominant diplopods Polydesmus denticulatus and Mecogonopodium carpathicum, both widespread across the depth gradient, a vertical segregation of early post-embryonic stages was found. While P. denticulatus tended to undergo the early stages of development in the soil-filled topmost levels, the early juvenile stage of M. carpathicum was distributed deep in the scree slope profile.     

Raspailiidae (Porifera: Demospongiae: Axinellida) from the Mexican Pacific Ocean with the description of seven new species

The taxonomy of the family Raspailiidae has always been controversial. The family was first included in the order Poecilosclerida. It was then allocated to the order Axinellida and later moved back to Poecilosclerida. Currently with the development of molecular tools it has been assigned to the order Axinellida. In this contribution we describe 10 species from the Mexican Pacific Ocean. Seven of them are new to science: Raspailia (Parasyringella) rubra sp. nov., Raspailia (Raspaxilla) hymani (Dickinson 1945 Dickinson, MG. 1945. Sponges on the Gulf of California. Allan Hancock Pac Exp, 11(1): 1–251.  [Google Scholar]), Raspailia (Raspaxilla) hyle (de Laubenfels 1930 de Laubenfels, MW. 1930. The sponges of California. (Abstracts of dissertations for the degree of doctor of philosophy). Stanford Univ Bull, 5(98): 24–29.  [Google Scholar]), Aulospongus cerebella (Dickinson 1945 Dickinson, MG. 1945. Sponges on the Gulf of California. Allan Hancock Pac Exp, 11(1): 1–251.  [Google Scholar]), Aulospongus californianus sp. nov., Aulospongus aurantiacus sp. nov., Eurypon patriciae sp. nov., Eurypon tylospinosum sp. nov., Eurypon diversicolor sp. nov. and Eurypon brunus sp. nov. We discuss the genus Eurypon and include a table for all the species described worldwide with some comments about this genus. http://www.zoobank.org/urn:lsid:zoobank.org:pub:D462084B-EE9C-4C61-884A-C9DB70003B4A
