  • In the year 2000 we culminated a successful five year investigation of climate change by completing a preliminary east-west transect across Mongolia. An earlier tree-ring study at Tarvagatay Pass, Mongolia indicated unusual warming during the 20th century similar to other paleo-investigations of the northern hemisphere. This record had represented one of the few tree-ring records for central Asia. New data from several sites in western Mongolia confirmed the preliminary temperature. The highest twenty-year growth period for the composite record is from 1973-1994. The western Mongolian record was significantly correlated with the Taimyr Peninsula and two northern hemisphere temperature reconstructions reflecting large-scale temperature patterns while showing some important regional differences. These differences should prove useful for climate models. We have also developed a millennial length temperature-sensitive record at the Solongotyin Davaa site (formerly Tarvagatay Pass) using relict wood and living trees. Conspicuous features over the last 1000 years are a century scale temperature decline punctuated by the end of the Little Ice Age in the late-1800s and 20th century warming. The record also shows a cold period early in the 12th century and warm intervals late in the 10th, early in the 15th and at end of the 18th centuries. Despite a limited sample size before 900 AD, the long Solongotyin Davaa record is useful in indicating severe cold events and suggests some cold intervals nearly as severe. These tree ring series, spanning much of the circumpolar northern treeline, have been compiled to create a long-term reconstruction of the Earth's temperature over centuries. The new chronology, in addition to its value as a detailed record of Mongolian climate, provides independent corroboration for such hemispheric and global reconstructions and their indications of unusual warming during the 20th century.

  • The genus Tinocallis Matsumura, 1919 is one of the large genera of the subfamily Calaphidinae with 19 species worldwide. From recent expeditions in Laos, we recognized the heavy infestation of Tinocallis himalayensis Ghosh, Ghosh & Raychaudhuri, 1971, which is new record in Laos, on Queen's crape-myrtle, Lagerstroemia speciosa (Lythraceae). In this paper, the diagnosis and illustrations for the alate viviparous female are provided with the images of live aphids and damage on host plant.

  • A new record of the eyeshade sculpin Nautichthys pribilovius is described on the basis of a single specimen collected from the East Sea, Korea. The species has 23 second dorsal fin rays, rounded spines on the occiput, a black band through the eye and across the cheek, branched caudal fin rays and a branchiostegal membrane attached to the isthmus. The new Korean name "Gum-eun-tti-nun-hoet-dae-sok" is proposed for the genus Nautichthys, and "Gum-eun-tti-nun-hoet-dae" is proposed for the species N. pribilovius.

  • Single specimen (68 mm TL) of the Shiho's seahorse Hippocampus sindonis collected from Geomun Island was described as a first record from Korea. The species is characterized by having 15 dorsal fin-rays, 14 pectoral fin-rays, snout length 2.8 in HL, trunk rings 10, and tail rings 37. A new Korean name, "Sin-do-hae-ma" is proposed.

  • Flies of the genus Lispe are large, dark gray, and have well-developed palpi. Most Lispe species are found in damp sandy and muddy environments, such as borders of marshes, seashore areas, swamps, lakes, ponds, streams, and rice paddy fields. Both adults and larvae are predators of various small aquatic insects. Previously, five species of Lispe had been identified in Korea: L. assimilis Wiedemann, 1824, L. litorea Fallén, 1825, L. orientalis Wiedemann, 1824, L. patellitarsis Becker, 1914, and L. tentaculata (DeGeer, 1776). In this paper, we record a sixth Lispe species, L. consanguinea Loew, 1858, for the first time in Korea. The diagnosis and illustrations of this species are provided in addition to a key to the Korean Lispe species.

  • Abludomelita rotundactyla (Ren, 2012), belonging to the family Melitidae Bousfield, 1973 has been collected from Baengnyeongdo Island and Yangyang in Korea. This species was previously known from Yellow Sea, China and Sakhalin Island, Russia. Abludomelita rotundactyla is morphologically distinguished from congeners by gnathopod 2, palm excavate, defined by midventral acute process; gnathopod 2 with prominently plump dactylus; pleonites and urosomites dorsal formulae 7-9-9-5-4; and epimeron 3 with posterior serrations. The newly recorded species in Korea, A. rotundactyla is well accorded with the original description except for the number of pleonites dorsal teeth. The newly recorded species is described and fully illustrated in the present study. A key to the Abludomelita species in Korea is also provided. This additional record now brings the total recorded number of abludomelitid species to three in Korea.

  • Based on a single specimen (49.9 mm SL) collected from Incheon River estuary, south-western Korea, Gymnogobius cylindricus was described as the first record from Korea as well as the westernmost record of the world. The species is characterized by having a large maxilla extend far beyond posterior margin of eye, dorsal fin with VI-I, 12 rays, anal fin with I, 11 rays, and without dark blotches and dots on lower part of body and caudal fin, respectively. A new Korean name, "Ga-neunsal-mang-dug" is proposed for the species.

  • The record continuum theory is now being studied in Australia, wherein the segregated record management of current, semi-current, and past records based on the temporal flow of the life cycle theory are being critcized. In addition, it emerged as a new paradigm for electronic record management without time and spatial constraints. Moreover, it is recognized as a logical and conceptual entity rather than as a fixed physical object. It also makes it possible to record multiple records in consideration of the complex, multidimensional environment of records. Based on this record continuation theory, the current information and communications technology (ICT) is applied to the four axes and dimension of the record continuation diagram of theoretical researcher Frank Upward. The researchers aim to realize a video recording management method suitable for the electronic record age.

  • To explore species diversity of Hypocreaceae, collections from Guangdong, Hubei, and Tibet of China were examined and two new species and a new Chinese record were discovered. Morphological characteristics and DNA sequence analyses of the ITS, LSU, $EF-1{\alpha}$, and RPB2 regions support their placements in Hypocreaceae and the establishments of the new species. Hypomyces hubeiensis sp. nov. is characterized by occurrence on fruitbody of Agaricus sp., concentric rings formed on MEA medium, verticillium-like conidiophores, subulate phialides, rod-shaped to narrowly ellipsoidal conidia, and absence of chlamydospores. Trichoderma subiculoides sp. nov. is distinguished by effuse to confluent rudimentary stromata lacking of a well-developed flank and not changing color in KOH, subcylindrical asci containing eight ascospores that disarticulate into 16 dimorphic part-ascospores, verticillium-like conidiophores, subcylindrical phialides, and subellipsoidal to rod-shaped conidia. Morphological distinctions between the new species and their close relatives are discussed. Hypomyces orthosporus is found for the first time from China.
