The East Side Story – The Transylvanian latest Cretaceous continental vertebrate record and its implications for understanding Cretaceous–Paleogene boundary events

The latest Cretaceous continental vertebrate faunas of the wider Transylvanian area figured prominently in discussions concerning the Cretaceous–Paleogene Boundary (K-Pg) events when they were first described by Nopcsa between 1897 and 1929, because they were assumed to be late Maastrichtian in age. Subsequently their age was reconsidered as early Maastrichtian, and were thus regarded of lesser importance in understanding the K-Pg boundary events in Europe and worldwide. Moreover, Transylvanian continental vertebrate assemblages (the so-called ‘Haţeg Island’ faunas) were often lumped together as a temporally restricted assemblage with a homogenous taxonomic composition. Recent fossil discoveries and more precise dating techniques have considerably expanded knowledge of the Transylvanian vertebrate assemblages, their ages, and their evolution. A synthesis of the available stratigraphic data allows development of the first comprehensive chronostratigraphic framework of the latest Cretaceous Transylvanian vertebrates. According to these new data, expansion of continental habitats and emergence of their vertebrate faunas started locally during the latter part of the late Campanian, and these faunas continued up to the second half of the Maastrichtian. During this time, long-term faunal stasis appears to have characterized the Transylvanian vertebrate assemblages, which is different from the striking turnovers recorded in western Europe during the same time interval. This suggests that there was no single ‘Europe-wide’ pattern of latest Cretaceous continental vertebrate evolution. Together, the available data shows that dinosaurs and other vertebrates were relatively abundant and diverse until at least ca. 1 million years before the K-Pg boundary, and is therefore consistent with the hypothesis of a sudden extinction, although this must be tested with future discoveries and better age constraints and correlations.

Preventive disaster management of extreme natural events

Several recent extreme natural events resulted in great humanitarian tragedies because of weak preventive disaster management. Here we analyze several factors (natural, economical, political, awareness, and preparedness) that brought about the humanitarian tragedies of the early 21st century. We discuss then the role of science in the preventive disaster management of extreme natural events.

中国地理学会与《地理学报》的发展

中国地理学会前身是1909年在天津成立的中国地学会。1934年3月中国地理学会的成立与同年9月《地理学报》的创办,不仅是中国地理学科史上的大事,也是中国教育史乃至科学史上的亮点。这是新文化运动中所提倡“赛先生”,即科学观念不断在近代中国传播的重要节点。中国地理学会的成立,清晰地将近代地理学与传统舆地学分离开来,以独立学科的形态出现在中国历史舞台上。《地理学报》的创刊,则使中外地理学家们在中国开始享有高水准的专业学术窗口。这是中国地理学界仁人志士对“科学救国”“科技兴国”等思潮的实践。在中国地理学会的组织和推动下,老一代地理学家艰苦奋斗,将一系列重要的研究成果刊登在《地理学报》,中国地理学家在当时的国家顶层设计中占有了一席之地。虽然,当时对地理科学的重要性认知还主要停留在权力高层与专业学术圈内,但为后来中国地理科学的蓬勃发展播下了火种,也为唤醒普通民众的地理科学意识打下了坚实的科学基础。回顾历史,中国地理学会的成立与《地理学报》的创办可谓是中国地理科学的发轫,自此成为中国地理科学发展的推动者和见证者。值此中国地理学会创立110周年、《地理学报》创刊85周年之际,深入领会“不忘初心、牢记使命”,回顾中国地理学会与《地理学报》发展,以继承和发扬老一辈地理学家的精神,进一步推动地理科学发展,使之成为可持续发展的基础学科,更好地服务于国家建设,服务于人类命运共同体建设。     

AIDS to Successful Photography

Abstract

The National Geographic Society's Geography Education Program continues to work on improving geography in the nation's schools. A successful network of geography education Alliances is in place across the United States. These state-based Alliances emphasize grass-roots involvement by teachers and other geography educators. Features of the Geography Education Program include inservice teacher training at Alliance-sponsored summer institutes, institutes held at the Society's headquarters in Washington, and specialized institutes devoted to a specific topic such as technology in education, or water issues. In the near future, the Society's projects include urban outreach, technology training and application, development of preservice programs, and the implementation and dissemination of world-class standards in geography.

关心青年焦虑未来──中国地震学会会员情况的统计分析

本文对中国地震学会会员情况的资料从年龄、学历、职称、性别、地区和部门等的分布进行了统计分析。中国地震学会吸引了广大地区和不同部门的大量地震工作者，作为中国地震学界的群众性学术团体，具有充分的代表性和权威性。然而，目前学会存在着年龄老化、后继乏人的严重问题，１０余年后会出现７０％现有会员进入退休年龄的局面。建议中国地震学会应采取适当措施，吸引国内外的青年学子更积极地参与学会的活动，发挥他们的才能。对于未来１０余年中即将退休的大批地震学者，也应及时采取措施，发挥这批宝贵人才在科研、咨询、开发等方面的作用。
