Megaxyela Ashmead, 1898 comprises 13 species, four of which are described as new and one is removed from synonymy: Megaxyela euchroma Blank, Shinohara & Wei sp. nov. from China (Zheijang), M. fulvago Blank, Shinohara & Wei sp. nov. from China (Hunan, Jiangsu, Zhejiang), M. inversa Blank & D.R. Smith sp. nov. from the USA (West Virginia), M. langstoni Ross, 1936 sp. rev. from the eastern USA, and M. pulchra Blank, Shinohara & Sundukov sp. nov. from China (Hubei, Jilin, Liaoning, Shaanxi, Tibet), South Korea (Kangwon-do) and Russia (Primorskiy Kray). The male of M. parki Shinohara, 1992 is described for the first time. A lectotype is designated for M. gigantea Mocsáry, 1909. A cladogram, based on COI sequences of seven species, is presented and interpreted in view of selected morphological characters. Records of M. fulvago sp. nov. from Hunan and of M. pulchra sp. nov. from Tibet extend the known distribution of Megaxyela in the Old World 600 kilometers farther south and 2500 kilometers farther west than previous records.

Pyramica hexamerais a tiny predatory ant that feeds on minute soil arthropods. Originally from East Asia,P. hexamerahas been recently introduced to North America, apparently through human commerce. Here we document the known range ofP. hexamerain Asia and the New World. We compiled and mapped 73 site records ofP. hexamera, all from East Asia and the southeastern US. In Asia,P. hexamerarecords range from 21.9°N to 36.4°N (earliest date and number of sites in parentheses) in Japan (1949; 25), South Korea (1982; 2), and Taiwan (1992; 6). In the US,P. hexamerarecords range from 28.6°N to 34.3°N: in Florida (1987; 2), Louisiana (1987; 5), Mississippi (2003; 32), and Alabama (2007; 1).Pyramica hexamera is reported for the first time from Alabama.

Trhypochthonius nigricans and T. cladonicolus are redescribed on the basis of type specimens originating from C. Willmann’s collection and comparative material from Poland, Canada and the USA. The taxonomic importance of some morphological characters is analysed. Shape of the sensillus does not seem to be a good diagnostic character in the genus Trhypochthonius. Trhypochthonius sphagnicolus is recognized as a junior synonym of T. nigricans and T. cladonicolus is noted for the first time from the North America.

In 1972, the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter (London Convention) was negotiated. It is a global treaty, for the first time, to regulate dumping of waste at sea worldwide. Following this global endeavor, the Protocol to the London Convention (London Protocol) was later agreed to further modernize the London Convention so as to reinforce the management of dumping of waste at sea. While in East Asia, only China, Japan, the Republic of Korea (South Korea) and the Philippines have acceded to the Convention and its Protocol, other countries do not show their willingness to sign them. Against this background, this article will address the responses of these East Asian states to the implementation of the London Convention, and analyze and assess their relevant laws and regulations with particular reference to China’s practice. In addition, it will focus on new challenges, such as offshore carbon storage, to the London Convention.

Development of hydrogen utilisation for energy applications has seen promising innovation towards the future prospect of clean and sustainable energy, benefitting various aspects of environmental, social, industrial and energy security. In the APEC region, several economies, such as the USA, China, Australia, Japan and South Korea, have shown interest in the development of hydrogen technology for energy applications. These economies have been devoting effort towards research and development programmes, pilot projects and, up to a certain point, implementing it in their communities. In addition, these economies each have their own tailored hydrogen roadmap or strategy, ensuring a smoother path towards hydrogen development. In this mini-review, we analysed the approaches of three selected economies in the East Asia region towards hydrogen technology, namely China, Japan and South Korea. Each of these economies have their own strategies and priorities towards the application, production and future development of hydrogen technology. This review also analyses the future possibilities for the integration of hydrogen technology into various sectors, as well as various constraints faced by each economy. Therefore, the review might serve as a valuable reference towards the feasibility of future hydrogen technology development in the East Asia and APEC region.

Anisandrus maiche Stark, an ambrosia beetle native to Asia, is reported for the first time in North America based on specimens from Pennsylvania, Ohio, and West Virginia. This is the twentieth species of exotic Xyleborina documented in North America. This species, along with three others occurring in North America, were formerly placed in Xyleborus Eichhoff, but currently are assigned to Anisandrus Ferrari. Descriptions of generic characters used to separate Anisandrus from Xyleborus, a re-description of the female A. maiche, and an illustrated key to the four North American species of Anisandrus are presented.

The world's gliding mammals are an extraordinary group of animals that have the ability to glide from tree to tree with seemingly effortless grace. There are more than 60 species of gliding mammals including the flying squirrels from Asia, Europe and North America, the scaly-tailed flying squirrels from central Africa and the gliding possums of Australia and New Guinea. But the most spectacular of all are the colugos – or so called flying lemurs – that occur throughout South-East Asia and the Philippines. Animals that glide from tree to tree descend at an angle of less than 45 degrees to the horizontal, while those that parachute descend at an angle greater than 45 degrees. Gliding is achieved by deflecting air flowing past well-developed gliding membranes, or patagia, which form an effective airfoil that allows the animal to travel the greatest possible horizontal distance with the least loss in height. The flying squirrels and scaly-tailed flying squirrels even have special cartilaginous spurs that extend either from the wrist or elbow, respectively, to help support the gliding membrane. Gliding Mammals of the World provides, for the first time, a synthesis of all that is known about the biology of these intriguing mammals. It includes a brief description of each species, together with a distribution map and a beautiful full-colour painting. An introduction outlines the origins and biogeography of each group of gliding mammals and examines the incredible adaptations that allow them to launch themselves and glide from tree to tree.

The current crisis in Catalonia and the issue of its future status is a well-known example of challenges which can be observed throughout Europe and the world: demands for autonomy and tendencies towards secession. The chapters in this volume deal with various examples of such phenomena in Europe (Catalonia, Corsica, Cyprus, Flanders, Scotland, South Tyrol, the former Czechoslovakia) and in other parts of the world: the Middle East (the case of the Kurdish people), North America (Québec and the USA) and East Asia (Hong Kong) With contributions by Elisabeth Alber, Heinz-Jürgen Axt, Helga E. Bories-Sawala, Frédéric Falkenhagen, Horst Förster, Martin Große Hüttmann, Rudolf Hrbek, Lukas Mariacher, Simon Meisch, Peter Pawelka, Sebastian Relitz, Sabine Riedel, Georg Schild, Markus Stoffels, Gunter Schubert

Thuja, with 5 extant species, exhibiting a disjunctive distribution between East Asia (3 species) and North America (2 species), was investigated with respect to the morphological characters of foliage and cones by LM and SEM. Here we provide 2 keys to all 5 species of Thuja based on the cones and foliage respectively, which not  only can be used for identifying extant Thuja at the species level, but also have a great potential for recognizing and/or linking the fossil species to living ones, and further tracing the evolutionary history of the genus.

The polypore Trametes gibbosa (Pers.) Fries, common in Europe and Asia, is reported from eastern North America for the first time. Single basidiospore cultures from Pennsylvania, United States, and Quebec, Canada, were paired with each other and with cultures from the Czech Republic. The North American intercollection crosses were 60% compatible and 100% compatible with the Czech cultures. All the crosses among the Czech cultures were 100% compatible. The recent introduction of T. gibbosa to North America is suggested as a possible explanation for the limited number of mating-type alleles and subsequent incompatibility among the North American cultures.
