Fouling acorn barnacles in China——a review

We review the species composition, distribution, and seasonal variation of fouling acorn barnacles in Chinese waters--from Bohai Sea and Yellow Sea to East and South China Seas. Thirty-two species of acorn barnacles were found, of which, the dominant species are Amphibalanus amphitrite, A. reticulatus, A. variegates, Balanus trigonus, Fistulobalanus kondakovi, Megabalanus tintinnabulum, Striatobalanus amaryllis, and Eurapha withersi in the fouling communities. A. amphitrite is the dominant species in the coastal waters of Bohai Sea and Yellow Sea and A. reticulatus is dominant in the East and South China Seas. The settlement period of fouling acorn barnacles is usually in summer and autumn. From north to south with the decrease of latitude, their settlement period obviously extends, even to the whole year, and the species number also increases. Other environmental factors, such as salinity and distance from shore, also play an important role in the distribution of fouling acorn barnacles.

Review of Anobothrus (Polychaeta: Ampharetidae) from China

We reviewed ampharetid genus Anobothrus Levinsen, 1884 in China seas based upon material deposited in the Marine Biological Museum of the Chinese Academy of Sciences （Qingdao）. The genus includes A. glandularis （Hartmann-Schr6der, 1965）, A. gracilis （Malmgren, 1866）, A. mironovi Jirkov, 2008 and A. nataliae （Jirkov, 2008）. A. glandularis and A. mironovi are recorded for the first time in Chinese waters. A key to Chinese species of Anobothrus is given.

日本近代儒家文化元素重释及“右翼”思想的初现

日本进入近代之际重释大义名分、尊王攘夷、华夷之辨等中国儒家文化元素，创制明治维新发动论，提出适合世界变局的“海国”论。值得注意的是，日本“右翼”思想及侵略理论也在这个时期初见端倪。

Re-interpretation of the classical geopolitical theories in a critical geopolitical perspective

Struggling for supremacy between great powers and the rise or fall and regime change of great powers are all subject to the Geopolitical Law. Geographers should keep in step with the times, accurately grasp the national interests, and seize the opportunity to contribute to the great rejuvenation of our nation. However, due to lack of criticism on the history and philosophy of geopolitics, we can neither accurately understand the geopolitical theory, nor effectively put the geopolitical theory into practice. This paper introduces the development of critical geopolitics, summarizes the three characteristics of critical geopolitics, and interprets the four classical geopolitical theories accordingly. In order to simplify the interpretation process, this paper firstly presents an analytical framework for interpretation of four classical geopolitical theories; secondly, focuses on interpretation of "The Geographical Pivot of History" put forward by Mackinder according to the analytical framework; finally, critically summarizes the four classical geopolitical theories. Through the critical interpretation, this paper draws a conclusion that there are the scientific, hypothetical and conceptual classical geopolitical theories. The construction of classical geopolitical theories is based on the international geopolitical structure, spatial distribution of national interests and inter-state spatial conflict, in order to show the identity of theoretical constructor, so as to reflect the historicality, sociality, situationality and geographical knowledge – power structure of geopolitical theories.
