Morphological Distribution

Through field survey and morphological research, this study has determined that the Camellia genus in Lam Dong province, Vietnam has a high diversity of morphological, distribution and taxa characteristics. The species of Camellia genus in Lam Dong province are mostly shrubs and small trees. The narrow oblong leaves are a very common and typical characteristic for Camellia in Lam Dong province. The flowers of the species of Camellia are diverse with four main colours is white, yellow, pink and purple. The fruits are globose, flattened globose, wrinkled or uneven edges. Especially, the obovoid fruit only occurs in Lam Dong province. Most of the species of Camellia genus in this province are endemic. The study has added ten species of the Camellia genus, brings the total of species of Camellia genus to Lam Dong province to between sixteen and twenty six. This is the first study to evaluate Camellia diversity in Lam Dong province. It is also the first complete statistics on the number of species of Camellia genus in Lam Dong province to confirm that this province is the second diversity centre of Camellia of Vietnam following the first centre in the North of Vietnam.

High Diversity

Using molecular markers and species delimitation analyses, a high diversity of bi-tentaculate Cirratulidae was discovered from the North-East Atlantic. Five new species are described: Chaetozone pseudosetosasp. nov., Chaetozone quintasp. nov., Chaetozone barentsensissp. nov., Chaetozone monteverdiisp. nov., and Chaetozone chambersaesp. nov. Several morphogroups are also described, even though the presence of cryptic diversity prevented naming of individual species. For each species presented, a molecular diagnostic is given from the universal barcode COI and, when available, the D1–D2 domains of the 28S rRNA. This increases the number of species in Chaetozone in northern European waters from ten to at least 17 species, the exact number of species remaining uncertain as taxonomic issues with older names remain unresolved.

AbstractThe aim of this paper is to demonstrate that much of the ‘hummocky moraine’ present within the northern part of the LochLomond Readvance ice cap formerly situated in the North West Scottish Highlands may be interpreted as suites of ice-front moraines deposited during active decay. These landforms can be used to reconstruct ice cap decay, whichleads to important insights into the shrinking form of the ice cap and associated environmental conditions. Evidence has been collected from 10803 airphotographs and from detailed field survey. It is presented at three spatial scales.

Статья посвящена металлическим сосудам раннего и среднего периодов бронзового века Анатолии. Цель исследования – попытка провести анализ хронологического и морфологического распределения металлических сосудов в регионе и уточнить их назначение, социальные и ритуальные функции с позиций анализа контекста обнаружения. В соответствии с поставленной целью материал рассматривается в нескольких аспектах: динамика распространения металлической посуды во времени; морфология и материал находок; функциональное назначение и социальные практики использования металлических сосудов. Автор подчеркивает значение таких находок для определения комплекса как элитарного, а также в связи с их функциональным использованием в ходе общественно значимых событий, таких, как церемониальная трапеза, в том числе погребальное пиршество. Несмотря на относительную малочисленность данной группы находок, металлические сосуды следует рассматривать как один из важных признаков иерархической структуры раннегосударственного общества, сложения цивилизаций ближневосточного типа. Это косвенно подтверждается отсутствием металлической посуды в памятниках III тыс. до н. э. в Северном Причерноморье. The paper explores metal vessels from the early and the middle periods of the Anatolian Bronze Age. The study attempts to analyze the chronological and morphological distribution of metal vessels in this region and clarify their purpose, social and ritual functions by analyzing the context of archaeological finds. In line with this aim, metal vessels are considered from several aspects: changes in their distribution over time; morphology and the material the finds are made from; functional purpose and social practices metal vessels were used in. The author emphasizes relevance of such finds for categorizing assemblages containing metal vessels as elite ones as well as highlights their significance in relation with their use in socially important events such as ceremonial feasts, including funerary feasts. Despite a relatively limited number of finds attributed to this group, metal vessels should be regarded as one of eloquent markers of a hierarchical structure of society in early state formations and development of civilizations of the Near Eastern type. The said is indirectly confirmed by absence of metal vessels in the III mill. materials from the North Ponticregion.

Description of five new Dolichopoda species from the Ionian area of Western Greece together with a description of the female for D. pavesii from Kefalonia island and the male of D. dalensi from North-eastern Peloponnisos are reported. Considering the other 6 species already documented in the area (including the North of the Peloponnisos), there is now a total of 11 recorded species of Dolichopoda which currently inhabit the underground areas of this zone. These new data, therefore, help better define the already high diversity of the genus in the Hellenic region (25 species in all) reinforcing the hypothesis that there was a central area of dispersion of the Dolichopoda in the ancient Aegean plate.

Main Deformation

<p>We analysed at very high detail the surface deformation along a volcanotectonic structure in the Krafla Fissure Swarm, located in the North Iceland Rift. The structure affects the Pleistocene Hituholar volcano and 12 ka old lava flows. The work has been carried out through the Structure from Motion technique (SfM) applied to UAV surveys, integrated with a lithostratigraphic and structural field survey. The resulting Orthomosaic and Digital Surface Model (DSM) have a resolution of 2.6 and 10 cm, respectively. The zone of deformation is characterised by topographic bulging, parallel extension fractures, and narrow grabens with locally floor uplift, which can be explained as the effect of shallow propagation of a dyke northward from the Krafla magma chamber. In fact, the study area has been interested by northward dyke propagation from the central Krafla volcano during several rifting events, among which the recentmost occurred in 1975-1984 (Krafla fire). The analysis of the very wide area covered by our UAV surveys indicates that changes in the pattern of surface deformation occur in correspondence of contacts between deposits with different rheological properties: the transition from very stiff lavas to soft hyaloclastites produces a change from extension fracturing to normal faulting. Moreover, we detected a series of extension fractures with NE-SW strike and left-lateral slip component, and NNW-SSE strike and right-lateral component, which are rotated clockwise and anticlockwise respect to the main NNE-SSW graben trend, and extend outward to the sides of the main deformation zone up to 17 m. We interpret these structures as originated in front of the dyke tip during its propagation and being successively bypassed by the dyke advancement. In case of an active volcanic zone, the comprehension of the surface deformation and of the significance of strike-slip faulting occurrence can help to determine how and where magma is propagating. Thus, these evidences may help to decipher geophysical data and surface structural data during volcano monitoring.</p>

Late Roman

A programme, combining a physical survey, intensive pick-up and geophysics, was carried out over 17 ha around the site of a small late Roman fortification, some 6 km south of ancient Pydna. Although the area is intensively farmed, the pick-up survey proved remarkably successful. Hellenistic occupation was identified and a restricted Roman settlement around the site of the quadriburgium. Surprisingly, a new and large late Roman fortification (c. 3–4 ha), equipped with towers, with a densely occupied interior and ‘extramural’ buildings was also found. The north-eastern curtain was discovered by resistivity surveying, the line of the north-western and south-western sides by intensive survey. Pottery and brick monograms from the new site suggests that it dates to the second half of the sixth or possibly early seventh century. It is argued that the quadriburgium may be the site of ancient Anamon, a station on the coastal road from Thessaloniki to Dion. The newly discovered site, clearly of considerable importance, lay on the north bank of the river Sourvala and probably had direct access to the sea, importing both local pottery and amphorae from the eastern Aegean. Its role may have been to protect the fertile coastline of the Pieria and to provide a secure base for the export of agricultural products to the beleaguered cities and settlements around the Thermaic Gulf.

Deposit Feeding

Between 1980 and 1985 ninety-seven stations were sampled by Smith-Mclntyre grab from the offshore northern section of the North Sea. Four hundred and nine infaunal species were identified from the 76 selected macrofaunal stations. The number of species per station varied from 25 to 80 with a maximum abundance of 9,600 individuals m−2. The biomass ranged from 0.13 to 18.86 g dry weight m−2. At most stations, however, biomass varied between 1 and 4 g dry weight m−2. Diversity and abundance were highest in the 120–140 m zone, characterised by fine sand containing variable amounts of silt. The highest biomasses were recorded in two areas; firstly where stronger currents predominate and the sediments are coarser (east of Shetland and west of the Norwegian Trough), and secondly in the fine sandy deposits of the centrally located area. In the silty sediments (Fladen Ground and smaller depressions) there was a predominantly subsurface deposit-feeding community, whereas in the coarser area east of the Shetlands carnivores predominated. Over the remaining area surface deposit feeders were dominant.

Great Reforms

The notes that follow are the first results of a programme of field-survey undertaken by the writer and by various members of the British School during the autumn of 1954 in the area that lies immediately to the north of Rome, between the Tiber and the sea. This area is one that has been strangely neglected by modern students of Italian topography. Ashby's published work is concerned mainly with those parts of the Campagna that lie to the south and east of Rome; and Tomassetti's work, invaluable as a repertory of manuscript and published sources, lays no claim to be a comprehensive survey of the material remains surviving on the ground.Such a survey is badly needed today. The romantic desolation of Southern Etruria is being transformed from one day to the next under the impact of a scheme of landreform comparable in scale to the great reforms of classical antiquity, and vast estates which for centuries have been used for stock-breeding and seasonal pasture are being broken up and brought into cultivation with all the devastating thoroughness that modern mechanical equipment entails. Whole regions are accessible today as they have never been before, and within them the bulldozer and the mechanical plough are busy destroying whatever lies in their path.

State Of Affairs

One of the most remarkable evolutionary processes, the more striking since it has occured before our eyes, has been the rise and spread of melanism and melanochroism amongst the Lepidopetera. Commencing about 1850 in the Manchester area in England with the Geometrid moth Amphidasys betularia L., which yielded the black form carbonaria Jord. ( doubledayaria Mill.), this development has proceeded so rapidly, and become so widespread, that now there is scarcely a country in Northern and Central Europe which does not produce its quota of melanic insects. Moreover, the same state of affairs exists in the North-Eastern United States, although there the number of species affected, up to the present, is not so great as in Europe. Another important feature about these changes lies in the circumstance that, almost uniformly, in Europe and in the United States, the first species to exhibit melanism in any given area have been Amphidasys betularia and Tephrosia crepuscularia . From the beginning, the Geometridæ, more especially the subfamily Boarmiinæ, have provided not only the bulk of the melanic varieties, but also the greatest numbers of individuals. In many areas, as for example in the case of A. betularia and Y psipetes trifasciata , only black examples occur. Nevertheless, other groups include species which have gone black; for instance, the Noctuidæ present black forms of Aplecta nebulosa Hufn., the Cymatophoridæ of Cymatophora or F., the Arctiidæ of Spilosoma lubricipeda L., the Gelechiidæ of Chimabacche fagella F., and so on.

AbstractIn March 1984 the British Geological Survey commenced an environmental geological study of parts of west Wiltshire and south east Avon for the Department of the Environment. The objective of this study was to collect the available geological data relevant to the area, and to present them as a series of thematic maps accompanied by a descriptive report and a database/archive of the data used.The output is intended to be used by land-use planners. It is designed simultaneously to be understandable by people not trained in geology and yet to contain detailed information required by specialists concerned with the environment and its development. The 14 maps which were produced describe themes which include solid lithostratigraphy, drift deposits, the inferred distribution of Great Oolite Freestone, the inferred distribution of fuller’s earth, groundwater, ground conditions in relation to groundwater, geotechnical properties of bedrock and superficial deposits, landslipped and cambered strata, distribution of slope angle, and mining.Although the task was primarily a desk study, it was found necessary to carry out a small amount of field survey to re-interpret the foundered strata to the north-west of Bath. This re-survey has been presented in a style consistent with the mapping of the rest of the study area. A fifteenth map showing the result of the re-interpretation of the foundered strata was produced as a supplement to the main report.This paper describes the methods and the results of this study and comments on the implications of the technique for land-use planning.
