The density of Santalum spicatum was compared between 'land systems' and between 'land surface types' on four sheep stations in the north-eastern Goldfields: Yakabindie, Tarmoola, Glenorn and Minara. S.A spicatum density was recorded in 4–6A ha transect plots, with a total of 14,090 ha surveyed. Within each transect plot, the S. spicatum were divided into five groups based on stem diameter at 150A mm: < 25 mm, 25–74 mm, 75–124 mm, 125–174 mm and > 174 mm. The proportion of S. spicatum in each of the five size categories was similar between land surface types and between land systems, with the majority in two groups: 75–124 mm and 125–174 mm. S. spicatum recruitment was low, with less than 1.5 % seedlings (< 25 mm) and 7.9 % saplings (25–74 mm). Total density of S. spicatum on hills and ridges (0.65 stems/ha) was significantly higher than any other land surface type. The sandplains (0.05 stems/ha) supported the least. Within land systems, Laverton and Bevon (both hills and ridges) had the highest S. spicatum density. Yakabindie supported higher densities of S. spicatum than the other stations.

Population size structure of sandalwood (Santalum spicatum) was studied on four pastoral leases near Paynes Find and Menzies, in semi-arid Western Australia. Stem diameter, height, height to crown and the orientation of dry-sided stems were recorded for 1017 individual sandalwood. Populations of S. spicatum at Paynes Find contained only mature trees, indicating no successful recruitment for at least 30 years. In contrast, populations of S, spicatum at Menzies had a high proportion of seedlings and saplings. Crown measurements of mature S. spicatum trees indicated high grazing intensity at Paynes Find: mean height to crown at Paynes Find (147-148 cm) was significantly higher than Menzies (92-94 cm). Dry-side percentage differed significantly between directional faces, consistent with sun damage. Highest mean dry-side percentages were on stem sides facing the sun between midday and late afternoon: west, north-west, south-west and north. This directional pattern was the same between pastoral leases, and there was no interaction between pastoral lease and dry-side direction. Mean percentage of mature trees with a dry-sided stem was also significantly higher at Paynes Find (76-82%) than at Menzies (42-46%). Significantly less foliage low to the ground on mature trees at Paynes Find may have exposed the stems to more sun damage. Land systems did not significantly influence dry-side direction on Burnerbinmah or Goongarrie. No S. spicatum seedlings or saplings had a dry-sided stem. Key words: Santalum spicatum, size structure, dry-sided stems

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.

In 1995 the black grouse was registered in the Polish list of protected species. The national black grouse protection plan has been prepared and a few regional projects of the conservation of grouse and its areas of occurrence have been implemented. Unfortunately, adverse trends have not been turned back in the majority of regions. On the other hand, the population occurrence area has even increased locally in the mountains. The registered changes in the area of black grouse occurrence indicate that this species has the greatest chance of survival in some mountain areas in the southern part of Poland and locally in lowlands in the north-eastern part of the country. However, it is necessary to stop and reverse the unfavourable environmental changes which have been registered in areas of black grouse occurrence.

Classifying and mapping of vegetated area in Al- Baha region, Saudi Arabia using remote sensing shows that the medium-high density vegetation is mostly found at the central part of Al-Baha region separating the highlands and the low lands. Results obtained show that only 862.5 km2 (7.7%) Al-Baha region is covered with medium-high density vegetation found mainly at the 6-15km width horizontal central belt (at districts of Al-Mandaq, Al-Baha and south Baljurashi) along high foggy mountainous plateau. Whereas, about 65% of Al-Baha region has very low-none density vegetation mainly occurred extensively at Tihama low plain towards the Red Sea and at the north-eastern desert plain. In addition, study reveals that the highlands of Al-Baha have the most numbers of trees represents the areas of the highest elevations in the region (range between 1940 and 2366 m above sea level. This indicates that there is relationship between this elevation range with medium to high vegetation density. Similarly, the low surface temperatures are mainly located at the central belt across Al-Baha region. When overlaid with medium-high vegetation density zone with the temperature map, it was visually observed that it almost fit with lower temperature zone of less than 15°C. This also indicates that there is relationship between lower temperature with medium-high vegetation density.

In the wild, Coni/urus penicillatus has two tail colour morphs, one entirely black and the other with a white distal brush of variable length. These colour morphs have been used in the past for taxonomic purposes. A small proportion (4'6%) of laboratory-reared animals have a white interstitial section. Pedigree data were collected from a laboratory colony (n = 173) established using seven wild-caught animals from the north Kimberley region, Western Australia. The hypothesis tested was that black tail is inherited as a Mendelian character recessive to white tip. Matings between black-tailed individuals always gave black offspring. Crosses between other colour morphs also supported this hypothesis.

The Article examines the preconditions of the struggle of the mountaineers Sevres-Eastern Caucasus in the 20-50-ies of the XIX century On the basis of analysis of sources and existing literature reveals the principal causes of the struggle of the mountaineers against the colonial policy of tsarism and the local rulers. It stresses that the dissatisfaction of the highlanders was caused by construction on arable land fortresses, device the so-called fortified lines with the Cossack settlements, permanent mobilization of the local population to build roads, fortresses, requirements, burdensome taxes and the heavy duties and activities assigned to mountain communities and possession of the king's officers and the commandant of managers to intervene in the internal life of the highlanders. The article talks about the brutal repression used by the Royal officials in relation to the unhappy mountaineers - the burning of entire villages, destruction of crops and grain reserves, the destruction of the gardens - all this aroused the indignation of the mountaineers and led to the struggle against tsarist oppression and local feudal lords. The article is subjected to criticism the concept of M. M. Bliev, if the mountaineers lived by raids on their neighbors. His thesis is that in the first half of the nineteenth century the mountaineers have experienced a period of expansion of tribal relations, not only clarifies the issue of their struggle in the 20-50 years of the XIX century, but also confuses the history of the peoples of the region. The publication highlights how local authorities based on the Royal arms, brutally oppressed rank and file of the highlanders, were taken from their last horse or bull, the last under the grain in the tax bill. The article presents material about the ill-treatment of Aslan-Khan Kyurinsky and the other lords with their subordinates. The feudal lords levied a population with taxes and duties at its discretion, enriched by direct robbery. Therefore, according to the article, the idea of anti-colonial protest in the minds of the highlanders were merged with the anti-feudal aspirations.

In this study, Bomolochus unicirrus Brian, 1902, a species of parasitic copepod belonging to the family Bomolochidae (Claus, 1875), was reported for the first time from the north-eastern Mediterranean waters off the Turkish coast. Parasites were collected from the gill filaments of the European barracuda, Sphyraena sphyraena(L.)captured by trawling in Iskenderun Bay, Turkey. The morphological features of B. unicirrus were Redescribed and illustrated based on the newly collected material. Key diagnostic characters and newly observed details in some structures are highlighted and supported by using scanning electron microscopy (SEM). Differences and simply overlooked details in previous descriptions of B. unicirrus, are discussed in detail. In addition, morphological comparisons between presently reported species and the other species of the genus Bomolochus Nordmann, 1832 were also presented.

At the early medieval site Břeclav – Pohansko we can distinguish two different types of funerary areas: church cemeteries with clearly defined locus sacer and dispersed burial grounds in settlements, where the boundary between the living and funerary spaces is not clearly defined. The organisation of the area for funerary activities, the selection of the burial place and the homogeneity of applied burial rites in the above-mentioned two types of funerary areas were different. In order to find out how extensive this difference is, we chose several characteristics of funerary areas and compared them with one another. The key determinants were: the spatial structure of funerary areas, and the orientation and position of individuals buried in grave pits. As an example of a church cemetery we chose the cemetery around the second church in the North-Eastern Suburb of Pohansko. The Southern Suburb of the stronghold yielded data related to funerary areas dispersed in and between settlement structures. The comparison of selected characteristics of burial customs identified in the above-mentioned church cemetery and in dispersed cemeteries demonstrates that burials around churches were most probably organised and planned centrally and that the organisation and supervision of funerary activities might have been in the hands of the clergy. The burials in cemeteries within the settlement structure, on the other hand, were organised in accordance with customs of local community. The organisation and supervision of these funerary areas were most probably in the hands of persons approved and authorised by the community, maybe some significant community member, or the “Council of Elders” or pagan priests.

Salt is an essential commodity for human beings, and its demand has been increasing in the markets since the early days. There was no information regarding salt production in Assam during the precolonial and colonial periods. On the other hand, small salt brines existed in places like Sadiya, Burhat and Naga hills, but they were unaffordable. At that time, people used Khar, the burn ashes of certain trees which produced a salty taste instead of ready-made salt. The salt became a symbol of wealth which helped people maintain a high status in the society of Assam as well as in the Goalpara district. The salt of Bengal became very famous because of its affordability—its supply was also available at Goalpara in the colonial period. Thus, Goalpara became the centre of salt trade of the north-eastern frontier countries. This article will attempt to highlight the salt trade and its significance in the colonial period.
