The molecular phylogeny of the Lardizabalaceae is reconstructed based on chloroplast trn L_F sequences alone and combined trn L_F and rbc L sequences. The phylogenetic topologies agree well with Qin's and Takhtajan's tribal classification in both analyses. Decaisneae and Sinofranchetieae are basal clades in the phylogenetic trees and external to all other taxa in the family. Lardizabaleae consisting of Boquila and Lardizabala are well supported in both trn L_F (100%) analysis and trn L_F and rbc L combined analysis (99%). Tribe Akebieae are strongly supported by a bootstrap value of 100% in both trn L_F analysis and trn L_F and rbc L combined analysis. However, the new genus Archakebia is nested within the genus Akebia in the trn L_F trees. In the combined trees, Archakebia is sister to Akebia with high bootstrap support. The inter_relationships among three closely related genera Parvatia , Holboellia and Stauntonia are still problematic. P. brunoniana ssp. elliptica is sister to H. latifolia in both analyses with low bootstrap support. H. parviflora is nested within the Stauntonia and sister to S. cavalerieana . Therefore, these three genera of tribe Akebieae may not be monophylytic and their generic boundary and delimitation need to be further studied, by exploring more molecular data, together with more morphological characters. 展开更多

The establishment of the ASEAN Earthquake Information Center (AEIC) was endorsed by the 40th Meeting of the Committee on Science and Technology held in October 2000, at the request of the ASEAN Sub-Committee on Meteorology and Geophysics (SCMG) to obtain the ASEAN Standing Committee’s (ASC) approval to officially use the name “ASEAN Earthquake Information Center (AEIC)”. As part of AEIC activities, the SCMG implemented a project on the ASEAN Seismic Network for Rapid Exchange of Strong Earthquake Data (ASNET RESED). The project was implemented by the ASCMG with funding support from the Government of Japan through the Japan ASEAN Co-operation Promotion Program (JACPP). The aim of the project is to facilitate the rapid exchange of data and information on earthquakes with magnitudes greater than 5.5 on the Richter scale, and to link all of the ASEAN National Seismological Centers through the Internet to disseminate earthquake information. For the future program, we propose a seismic data exchange between the National Seismological Centers in ASEAN countries as well as world seismological centers using the facilities in the AEIC. The plan is basically to develop and update the software and hardware in the NSC and AEIC for data communication. To refresh our knowledge in seismology and data communication, we arrange the training sessions for both topics. 展开更多
