Uniform Group

Most species of Euconnus (Cladoconnus) inhabit West Palaearctic, and only three are known from East Asia. The latter form a morphologically uniform group that comprises E. ussuriensis (Primorsky Krai), E. matsuae (Central Honshu) and E. nakahamai (Shikoku). These species cannot be reliably distinguished by external features; they differ mainly in the shape of the endophallic sclerites. Diagnostic characters of these species are summarized, and a new member of the E. ussuriensis species group is described, Euconnus (Cladoconnus) rudimentalis n. sp. (South Korea). Members of this group are restricted to the areas surrounding the Sea of Japan; the known distribution suggests that similar species can be expected to occur also in the northern part of the Japanese Archipelago and in North Korea.

Abstract. The spatial distribution of oxygen and hydrogen isotopic composition (δ18O and δ2H) of stream waters across Japan was clarified with a data set compiling sample data obtained from 1278 forest catchments during the summer of 2003. Both δ18O and δ2H values showed positive correlations with the mean annual air temperature and annual evapotranspiration, and negative correlations with latitude and elevation. Deuterium excess (d excess) values in stream waters were higher on the Sea of Japan side, and lower on the Pacific Ocean side, of the Japanese archipelago. The d excess in precipitation was generally higher in winter and lower in summer in Japan. The Sea of Japan side experiences a great deal of snowfall, and seasonal changes in monthly precipitation are rather small. In contrast, the Pacific Ocean side experiences a large amount of rainfall during summer with low levels of precipitation during the winter. Therefore, the lower d excess in stream waters on the Pacific Ocean side reflects summer precipitation, and the higher values on the Sea of Japan side are affected by delayed recharge from snowmelt. The isoscapes of stream water connote not only spatially integrated but also temporally integrated isotope signals of precipitation, and provide a framework for addressing applied hydrological, ecological, or meteorological research questions at regional scales, such as the effects of climate change.

Both δ18O and δ2H values showed positive correlations with the mean annual air temperature and annual evapotranspiration, and negative correlations with latitude and elevation. Deuterium excess (d-excess) values in stream waters were higher on the Sea of Japan side, and lower on the Pacific Ocean side, of the Japanese archipelago. The d-excess in precipitation was generally higher in winter and lower in summer in Japan. The Sea of Japan side experiences a great deal of snowfall, and seasonal changes in monthly precipitation are rather small.

Two New Species

Two new species of Caligus are described from the Japanese coast of the Sea of Japan. Caligus chinglonglinisp. nov. is based on a male specimen found in a plankton sample, whereas C. kajiisp. nov. was collected from the body surface of the host flathead Platycephalus sp. These two new species can be assigned to a distinct species group, the pseudorhombi group newly named and defined by the morphology of the genital complex in both sexes, and by the structure and armature of legs 2 and 4. The species group so far accommodates 19 species including these two new species. The morphology, host specificity and zoogeography of the species group are discussed herein and keys to species groups of Caligus and to species of the C. pseudorhombi species group are provided.

First Time

Abstract Negative Arctic Oscillation (AO) and western Pacific (WP) indices persisted from October to December 2012 in the Northern Hemisphere. For the first time, the monthly AO and WP were both negative for three consecutive months since records have been kept. Although in general negative AO and WP phases cause Siberia, East Asia, and Japan to be abnormally cold, Japan was relatively warm in October 2012 even though both the AO and WP were strongly negative. The temperature of the Sea of Japan reached a record-breaking high in October 2012, and it was found that heating by these very warm waters, despite the small size of the Sea of Japan, overwhelmed the cooling effect of the strongly negative AO and WP in October. Linear regression analyses showed that Japan tends to be warm in years when the Sea of Japan is warm. Consequently, the temperature over Japan is controlled by interannual variations of small-scale oceanic phenomena as well as by large-scale atmospheric patterns. Previous studies have ignored such small-scale oceanic influences on island temperatures.

A New Species

Previous research on the mitochondrial COI gene sequences of several populations of Limnoria nagatai Nunomura suggested a cryptic species from the Sea of Japan. A new species of algal-boring limnoriid is here described. Limnoria furca sp. nov. was collected from the holdfasts of Eisenia bicyclis on the Oki Islands and the Sea of Japan coast of Honshu and Kyushu Islands, Japan. L. furca sp. nov. is diagnosed morphologically by lacking a mandibular palp, faint subparallel carinae on the pleotelson, faint Y-shaped carinae on pereonite 5, the bifid lacinia mobilis of right mandible and the shapes of the secondary unguis on the pereopods. Similar species, L. segnoides Menzies, 1957 and L. nagatai Nunomura, 2012, are redescribed on the basis of the holotypes.
