This survey aims to determine the diversity and abundance of nematodes in some plants either horizontally or vertically. Observations horizontally ie by comparing the diversity and abundance of plants nemtoda woetel with different cropping ie monoculture and polyculture. While vertically observations made by comparing the abundance and diversity of nematodes from different soil depths are 0-10, 10-20, and 20-30 in the cabbage and tomatoes. The survey conducted on November 22, 2014, in the village of Sukatani, Cianjur Regency Indonesia. Survey sites located at an altitude of 1,200 meters above sea level, a survey using a zig-zag method, each sample was repeated three times. Laboratory analysis done by extracting the land acquired, and then counting the number of nematode populations obtained under the microscope. Results of the analysis showed there were eleven genus nemtoda obtained by the Rabditis sp., Pratylenchus sp., Helichotilenchus sp., Meloidogyne sp., Rotylenchus sp., Tylenchorynchus sp., Trichodorus sp., Criconemoides sp., Hoplolaimus sp., Dyctilenchus sp., and Monochus sp. spread either horizontally or vertically.

The phenomenon of synchronization (trapping) of coming waves by the resonant water area in a coastal zone of the sea found from the observed data is considered in the paper. Edge waves with the period of about 10.7 minutes are visually observed in sea level fluctuations near the village of Okhotskoye and the cape Ostri on the southeast coast of Sakhalin Island. These waves are synchronized with the resonance water area. It becomes apparent from the unlimited increase of a phase between the bottom stations installed at distance of about 7.5[Formula: see text]km. In relation to the phenomenon found, the problem of weak and periodic impact on regular self-oscillatory system — Van der Paul’s oscillator — is considered. Good compliance between theoretical model and data of experiments is obtained.

The village at Crystal River expanded greatly in size and permanence in Phase 2, which began sometime between around AD 200 and 300 and ended by around AD 500. This growth may have owed partially to a rise in sea level associated with the warmer temperatures of the Roman Warm Period, which might have made life on the seaward islands more difficult. The exchange of Hopewell exotics faded in this interval, but the societies of the Gulf Coast appear to have witnessed a fluorescence, as indicated by the widespread exchange of Swift Creek pottery and Weeden Island pottery. Crystal River was peripheral to these pottery traditions, but it may have been an important nexus between these and the Glades tradition of southern Florida, specifically with regard to the exchange of craft goods manufactured from marine shell. The gulf coast fluorescence is also indicated by a heightened pace of the construction of mounds. At Crystal River, three small platform mounds were initiated in this interval, clearly differentiating it from its peers in the region.

A ‘fauna’ of vertebrates recovered from a cavern-like deposit at a quarry near the village of Nehden in Sauerland is described and reviewed in some detail. Anatomical descriptions of some skeletal elements are given, where they provide new information or supplement previous descriptions.The clays in which the fossils were buried have been dated comparatively as Aptian (late Lower Cretaceous) and approximately contemporary with the Weald Clay unit of the Wealden Formation of southeast England and the Bernissartian of southwest Belgium. Both these latter formations have yielded faunal and floral assemblages that are very similar to those found at Nehden. The vertebrates collected at Nehden include adult and numerous juvenile remains of two species of the ornithischian dinosaur Iguanodon : I. atherfieldensis and I. bernissartensis . ( I. atherfieldensis is the more abundantly represented.) These can be contrasted with the massaccumulation of Iguanodon recovered from Bernissart, where these dinosaurs are represented by predominantly adult skeletons. There is circumstantial evidence from a documented association of bones (revealed by examination of excavation plans) to support a reconstruction of a juvenile Iguanodon bernissartensis with a body length ca. 2-3 m (fully grown individuals reach a body length of ca. 11 m); this is the smallest individual of this species recovered to date. The remainder of the vertebrate assemblage consists of very fragmentary remains of crocodilians, chelonians and extremely rare fish. The presence of both a hypsilophodontid ornithischian dinosaur and a theropod saurischian dinosaur must be viewed as extremely conjectural, based as they are on two very poor specimens. Remains referred to as Vectisaurus sp. in previous accounts of this site are juvenile individuals of Iguanodon . The circumstances surrounding three mass-accumulations of fossils, Trossingen, Bernissart and Nehden, are reviewed, and evidence of mass deaths among recent vertebrates is considered. Archive records at Trossingen suggest that periodic events, such as mud-slides, may have been partly responsible for the concentration of remains. Similar events may also have been responsible for the assemblages at Bernissart and Nehden; the assemblage at Nehden may represent an accumulation caused by a flash flood or by a herd crossing a river. It is suggested that awareness of such common phenomena should be emphasized when data such as these are used in estimations of numerical abundance and diversity of species in the fossil record; localized high abundances of species, caused by phenomena of this type, may exert a strong bias on the patterns of abundance or diversity of species, generated by palaeobiologists, by creating patterns that are in effect flash-flood artefacts rather than natural censuses of fossil faunas.

Woodeaton is a small Oxfordshire parish, four miles north-east of the centre of Oxford city and a little west of the wide marshy level of the ‘Plain of Otmoor.’ It stands on a low, detached and rounded hill, 315 feet above sea level, and 120 feet above Otmoor. In old days it must have been difficult of access, for Otmoor spreads away to the east of it; low pastures along the river Cherwell close it in on the north and west, while south-westwards, too, the land is low-lying and marshy. Even to the south-east a marshy hollow separates it from the wooded slopes of Beckley and Elsfield, once part of Shotover Forest. However, the well-known Roman road which connects Dorchester (Oxon.) with Alchester, and which passes along the foot of Shotover, and traverses the village of Beckley and the plain of Otmoor, runs within two miles of Woodeaton; in dry seasons it may have helped those who wished to get to the spot.

The village of Kalývia Sokhás lies against the base of one of the massive foothills in which Taygetus falls to the plain three or four miles to the south of Sparta (Plate 26, 1). It is bounded by two rivers which flow down in deep clefts from the mountain shelf. The hillside above rises steeply to a summit which is girt with cliffs on all but the west side and cannot be much less than four thousand feet above sea level; this von Prott believed to be the peak of Taleton. Its summit is crowned by the ruins of a mediaeval castle which was undoubtedly built as a stronghold to overlook the Spartan plain; the only dateable object found there, a sherd of elaborate incised ware, indicates occupation at the time when the Byzantines were in possession of Mystra. The location of the other sites mentioned by Pausanias in this region remains obscure, but fortunately that of the Spartan Eleusinion has not been in doubt since von Prott discovered a cache of inscriptions at the ruined church of H. Sophia in the village of Kalývia Sokhás. In 1910 Dawkins dug trenches at the foot of the slope immediately above the village and recovered a fragment of a stele relating to the cult of the goddesses and pieces of inscribed tiles from the sanctuary. The abundance of water in the southern ravine led von Prott to conclude that the old town of Bryseai with its cult of Dionysus also lay at Kalývia Sokhás; but no traces of urban settlement have come to light at the village, and the name rather suggests copious springs such as issue from the mountain foot at Kefalári a mile to the north where ancient blocks are to be seen in the fields.

Analysis of Heavy Metal Content of Pb, Cd, Cu, As in Water, Sediments and Bivalves in Coastal Waters of Balikpapan Bay. The study aims to analyze the levels of heavy metals (Pb, Cd, Cu, As) in water, sediment and Bivalvia and to determine the adsorption, bioconcentration factors in sediments and Bivalvia. This research is in the form of field survey and laboratory analysis, where the results are quantitative descriptive and analyzed statistically multivariate.The results of laboratory analysis showed that the levels of heavy metals in water ranged between (Pb 0.064-0.142 mg/L), (Cd 0.088-0.112 mg/L), (Cu 0.035-0.056 mg/L) and (As 0.022-0.026 mg/L). Sediment (Pb 2,555-2,616 mg/Kg), (Cd 2,433-2,609 mg/Kg), (Cu 1,289-1,553 mg/Kg), (As 0,329-0,496 mg/Kg) and Bivalvia (Pb 1,708-2,076 mg/Kg) ), (Cd 1.569-2.416 mg/Kg), (Cu 1.078-1.264 mg/Kg) and (As 0.297-0.449 mg/Kg). Heavy metal content of Pb, Cd, Cu and As in the sediment is greater than water or Bivalvia. The results of the statistical analysis partially showed that the levels of heavy metals Pb, Cd, Cu and As differed significantly between all study samples (water, sediment and Bivalvia). Whereas the observation stations (Kariangau industrial area, the village on the water and the PT. Pertamina area) did not differ significantly. The results of the analysis of adsorption and bioconcentration factors on the levels of heavy metals Pb, Cd, Cu and As in sediments (Pb 17.99-42.25), (Cd 22.75-28.67), (Cu 26.49-36.83 ) and (As 13.71-19.08). In Bivalvia (Pb 14.15-32.44), (Cd 14.00-26.55), (Cu 21.14-34.43) and As (13.50-29.88).

Tidal inundation, flood and land subsidence are the problems faced by Semarang city related to climate change. Intergovernmental Panel on Climate Change (IPCC) predicted the increase of sea level rise 18-59 cm during 1990-2100 while the temperature increase 0,6°C to 4°C during the same period. The Semarang coastal city was highly vulnerable to sea level rise and it increased with two factors, topography and land subsidence. The purpose of this study was to map the adaptive capacity of coastal areas in the face of the threat of disasters caused by climate change. The parameters used are Network Number, Employee based educational background, Source Main Livelihoods, Health Facilities, and Infrastructure Road. Adaptive capacity of regions classified into 3 (three) classes, namely low, medium and high. The results of the study showed that most of the coastal area of Semarang have adaptive capacities ranging from low to moderate, while the village with low capacity totaling 58 villages (58.62%) of the total coastal district in the city of Semarang.

Relocation as an adaptation strategy to coastal degradation remains on the fringes of climate change discourse. Yet, as sea levels are projected to rise, relocating is an inevitable response for vulnerable coastal communities worldwide. In fact, some Fijian villages are facing such severe coastal erosion that they have already begun the process of shifting to higher ground, and many more villages throughout the islands have been slated for relocation. This case study is based on the planned relocation efforts of Narikoso village on Ono Island in Kadavu, Fiji. In Narikoso, regional NGOs, INGOs, and local and national government are working with the community to relocate the village inland. The process of moving the community began in 2012 when Prime Minister Bainimarama sent the Fiji military to Ono Island to clear land for the new village. It came to an abrupt stop due to a lack of funding and ecological degradation caused by the preparation for the new village site. Since the relocation process began, a myriad of issues have arisen ranging from concerns regarding community engagement, availability of financial resources, and resistance to moving inland.

AbstractThree gravity cores (LZK1, ZKA4, and CSJA6) from the incised Yangtze paleo-valley comprise a thick sequence of the post-glacial deposit. Nineteen genera (26 species) of the benthic foraminifers are described from these cores, with detailed down-core foraminiferal variations to investigate their paleoenvironmental implications. Three foraminiferal assemblages are recognized for the lower, middle, and upper parts of the cores respectively. The lower part is dominated byAmmonia beccariivar. andFlorilus decoruswith lower abundance and diversity. In the middle part, the foraminifers are abundant and diverse, dominated by bothAmmonia beccariivar. andElphidium advenum.Cavarotalia annectens,Pararotalia nipponica, and porcellaneous benthic foraminiferal forms are always present, sometimes abundant. The upper part is characterized by theAmmonia beccarii-Elphidium magellanicumassemblage, except for the Core ZKA4, which is barren of foraminifers in this interval. AMS14C dates and foraminiferal assemblages both confirm that the transgression-regression sequence in these cores belongs to the “Ammoniatransgression” during the Holocene. In addition to documenting the post-glacial sea-level fluctuations, the benthic foraminifers also reflect a warmer climate during the early–middle Holocene. The foraminiferal differences among the three cores can be used to interpret the influence of seawater during the post-glacial sea-level fluctuations. The area in the vicinity of Core ZKA4 was affected by marine water only during the middle Holocene, which was much shorter than the areas of the other cores.

Monte d'Irsi is located approximately 6·5 km. east-southeast of the town of Irsina and 4 km. due west of the village of Santa Maria d'Irsi in the region of Basilicata. The archaeological site sits on the crown of an irregularly shaped plateau at around 480 m. above sea level; the land drops away steeply in all directions and the hill-sides are heavily eroded by stream beds which feed into the two major rivers in the area, the Bradano and the Basentello (Figs. 1 and 2 and Pl. XXVII, a). M. d'Irsi lies about 7·5 km. north-west of the confluence of the two, and since it is the highest point for 6 or 7 km. round about, forms an imposing feature of the landscape. No doubt it is this fact, connected with the proximity of M. d'Irsi to the very important Bradano valley (3 km. distant) that made the M. d'Irsi plateau a prime candidate for settlement even in prehistoric times and presumably in times of stress.
