(Polyplacophora: Leptochitonidae) and Its Phylogenetic Affinities

Sigwart National Museum of Ireland, Natural History Division, Merrion Street, Dublin 2, Ireland & School of Biology and Biochemistry, Queens University Belfast, BT7 1NN, UK Søren Bo Andersen Department of Earth Sciences, Aarhus University, DK – 8000 Aarhus C, Denmark Kai Ingemann Schnetler Fuglebakken 14, Stevnstrup, DK – 8870 Lang˚a, Denmark SYNOPSIS A new species of fossil polyplacophoran from the Danian (Lower Palaeocene) of Denmark is described from over 450 individual disarticulated plates. The polyplacophorans originate from the ‘nose-chalk’ in the classical Danish locality of Fakse Quarry, an unconsolidated coral limestone in whicharagoniticmolluscshellsarepreserved throughtransformation intocalcite.In platearchitecture and sculpture, the new Danish material is similar to Recent Leptochiton spp., but differs in its underdeveloped apophyses and high dorsal elevation (height/width ca. 0.54). Cladistic analysis of 55 original shell characters coded for more than 100 Recent and fossil species in the order Lepidopleurida shows very high resolution of interspecific relationships, but does not consistently recover traditional genera or subgenera. Inter-relationships within the suborder Lepidopleurina are of particular interest as it is often considered the most ‘basal’ neoloricate lineage. In a local context, the presence of chitons in the faunal assemblage of Fakse contributes evidence of shallow depositional depth for at least some elements of this Palaeocene seabed, a well-studied formation of azooxanthellic coral limestones. -
Chitons (Mollusca: Polyplacophora) Known from Benthic Monitoring Programs in the Southern California Bight

STEBBINS 1,* and DOUGLAS J. EERNISSE 2 1 City of San Diego Marine Biology Laboratory, Metropolitan Wastewater Department, San Diego, CA, USA 2 Department of Biological Science, California State University, Fullerton, CA, USA Abstract: About 36 species of chitons possibly occur at depths greater than 30 m along the continental shelf and slope of the Southern California Bight (SCB), although little is known about their distribution or ecology. Nineteen species are reported here based on chitons collected as part of long-term, local benthic monitoring programs or less frequent region-wide surveys of the entire SCB, and these show little overlap with species that occur at depths typically encountered by scuba divers. Most chitons were collected between 30-305 m depths, although records are included for a few from slightly shallower waters. Of the two extant chiton lineages, Lepidopleurida is represented by Leptochitonidae (2 genera, 3 species), while Chitonida is represented by Ischnochitonidae (2 genera, 6-9 species) and Mopaliidae (4 genera, 7 species). -
Mollusca, Polyplacophora) Movement Behaviour, with Comparison Between Habitats Differing in Complexity
The first observations of Ischnochiton (Mollusca, Polyplacophora) movement behaviour, with comparison between habitats differing in complexity Kiran Liversage1 and Kirsten Benkendorff2 1 Estonian Marine Institute, University of Tartu, Tallinn, Estonia 2 Marine Ecology Research Centre, Southern Cross University, Lismore, NSW, Australia ABSTRACT Most species of Ischnochiton are habitat specialists and are almost always found underneath unstable marine hard-substrata such as boulders. The difficulty of experimenting on these chitons without causing disturbance means little is known about their ecology despite their importance as a group that often contributes greatly to coastal species diversity. In the present study we measured among-boulder distributional patterns of Ischnochiton smaragdinus, and used time-lapse photography to quantify movement behaviours within different habitat types (pebble substrata and rock-platform). In intertidal rock-pools in South Australia, I. smaragdinus were significantly overdispersed among boulders, as most boulders had few individuals but a small proportion harboured large populations. I. smaragdinus individuals emerge from underneath boulders during nocturnal low-tides and move amongst the inter-boulder matrix (pebbles or rock-platform). Seventy-two percent of chitons in the pebble matrix did not move from one pebble to another within the periods of observation (55–130 min) but a small proportion moved across as many as five pebbles per hour, indicating a capacity for adults to migrate among disconnected habitat -

The goal of this study was to compare the chiton community structure of the rocky shore of Montepío during the dry and ‘nortes’ (stormy) weather periods, and to gather data on the relative growth of the dominant species. Sampling was carried out along a transect of 100 x 2 m in the intertidal zone and 83 individuals were collected. Six species were identified: Lepidochitona rosea, Chaetopleura apiculata, Ischnochiton kaasi, Lepidochitona pseudoliozonis, Lepidochitona liozonis and Acanthochitona andersoni. Species richness (S= 4) and Shannon diversity (1.36 and 1.29 bits ind-1 in dry and stormy seasons) were very similar between the 2 seasons; however, only 2 species occurred in both periods, suggesting a strong seasonal exchange of species (50%). -

A STUDY on the RELATIONSHIP BETWEEN KOREA and JAPAN in the 15Th CENTURY
Moon Hyoungjin A STUDY ON THE RELATIONSHIP BETWEEN KOREA AND JAPAN IN THE 15th CENTURY І. Introduction orea and Japan are geographically very close, yet feel so distant from each other. KBoth are neighboring countries, but there seems to be an invisible wall between them. Korea and Japan are on guard against each other, rather than being open-minded to each other. Until recently, Koreans needed a visa to visit Japan. Japan wanted to control the entry of Koreans to Japan with the visa system, but to no avail: due to Japan’s higher currency exchange rate and technological level, the number of Koreans entering Japan kept increasing day by day. In addition, Korean politicians wanted to establish a diplo- matic relationship with Japan in order to expand their political power, and Korean busi- nessmen wanted to trade with Japan to maximize their profits. Japan’s political power, bigger economic size, and higher currency value were factors that increased the number of Koreans entering Japan. But then, what had the relationship between the two countries been like in ancient times? Currently, Japan is richer, technologically more developed than Korea, but in an- cient times, the situation was opposite. Several Korean dynasties adopted Chinese culture and then developed their own unique cultures. At the same time Japan received advanced culture and technology from the ancient dynasties of Korea. Hence, Japan had to depend on several dynasties of Korea for several thousands of years. In the relationship between Korea and Japan, Korea was in the position of offering favors and benefits to Japan, whereas Japan was a marginal nation, which received culture from the advanced dynas- ties of Korea. -
