Permian to Recent rocks form narrow, roughly north- south and east-south-east trending belts in the north-eastern Transvaal. The rocks consist of a thin succession of Karoo sediments, a thick overlying succession of mafic and felsic volcanics referred to as the Lebombo Group, isolated outcrops of Cretaceous sediments and fairly extensive Tertiary-Recent Gravels and sediments. These rocks are in general well exposed along the eastern margin of the Kruger National Park and also crop out in the extreme north. Emplacement of the Lebombo volcanics and subsequent deposition of the Cretaceous rocks was intimately associated with the fragmentation of Gondwanaland.

SummaryTwenty-eight predominantly tropical bird species have ranges that only just extend into the north-eastern part of South Africa, mainly within the Kruger National Park (KNP). These species are listed as “rare” (200 breeding pairs) in the South African Red Data Book (Brooke 1984). This study assesses the extent to which six of these rare bird species represent viable populations in the KNP. Grid squares in the KNP (2.5 × 2.5 miles) were visually assessed according to several bird habitat parameters. Bird records were also plotted on this grid system and habitat associations were identified for each species. This allowed for the measurement of total suitable habitat within the KNP for each species. Bird densities within known habitat were determined using spot-mapping and fixed-distance strip-transect techniques. Estimated population sizes for each species were obtained by extrapolating density estimates to total suitable habitat. Of the six study species, Arnot's Chat, Rudd's Apalis, Wattle-eyed Flycatcher and Tropical Boubou are likely to occur in sufficient numbers to constitute viable populations within the KNP, with estimated population sizes of 1,394, 4/758/ 2,070 and 10,450 birds respectively. The populations of White-crowned Plover and Long-tailed Starling are probably too small to be viable in the long term, with estimated population sizes of 305 and 382 birds respectively. The results presented here are testable and can be used as a baseline for future monitoring.

Abstract A subhorizontal sandy series, the Gara Sayada series, some hundreds of meters thick, overlies a folded sandstone-shale series, more than 1,000 meters thick, on the north-eastern margin of the Eglab massif (Algeria) in the western Sahara. The intra-Caradocian (Ordovician) unconformity already known at several other localities in the Sahara is thus also represented in this region.

Abstract During geobotanical studies in the north-eastern border of hemi-boreal zone, in Valday (NW Russia), rare eutrophic deciduous forests dominated by oak Quercus robur were observed. A comparison of these forests with the model of European deciduous forest in Białowieża National Park (NE-Poland) indicates a great similarity. Therefore, eutrophic deciduous forests in Valday can be classified to the Querco-Fagetea class, the Fagetalia sylvaticae order and to the Capinion betuli alliance, despite the absence of hornbeam Carpinus betulus in the region. Rarity of eutrophic deciduous forests in Valday region results probably from strong anthropogenic pressure in the past.

Distribution Ranges

Documenting current species distribution patterns and their association with habitat types is important as a basis for assessing future range shifts in response to climate change or other influences. We used the adaptive local convex hull (a-LoCoH) method to map distribution ranges of 12 ungulate species within the Kruger National Park (KNP) based on locations recorded during aerial surveys (1980–1993). We used log-linear models to identify changes in regional distribution patterns and chi-square tests to determine shifts in habitat occupation over this period. We compared observed patterns with earlier, more subjectively derived distribution maps for these species. Zebra, wildebeest and giraffe distributions shifted towards the far northern section of the KNP, whilst buffalo and kudu showed proportional declines in the north. Sable antelope distribution contracted most in the north, whilst tsessebe, eland and roan antelope distributions showed no shifts. Warthog and waterbuck contracted in the central and northern regions, respectively. The distribution of impala did not change. Compared with earlier distributions, impala, zebra, buffalo, warthog and waterbuck had become less strongly concentrated along rivers. Wildebeest, zebra, sable antelope and tsessebe had become less prevalent in localities west of the central region. Concerning habitat occupation, the majority of grazers showed a concentration on basaltic substrates, whilst sable antelope favoured mopane-dominated woodland and sour bushveld on granite. Buffalo showed no strong preference for any habitats and waterbuck were concentrated along rivers. Although widespread, impala were absent from sections of mopane shrubveld and sandveld. Kudu and giraffe were widespread through most habitats, but with a lesser prevalence in northern mopane-dominated habitats. Documented distribution shifts appeared to be related to the completion of the western boundary fence and widened provision of surface water within the park. Conservation implications: The objectively recorded distribution patterns provide a foundation for assessing future changes in distribution that may take place in response to climatic shifts or other influences.

An analysis was made of arboreal Coleoptera on Leucosidea sericea from the Golden Gate Highlands National Park in the north-eastern Orange Free State, Republic of South Africa. Five sites were selected from which samples were taken, using a beating technique, at equal intensity, during 13 consecutive months. A total of 117 species representing 35 families were recorded and allocated to four guilds, namely phytophages (47 species), predators (44 species), scavengers (16 species) and tourists (10 species). This diversity is attributed to the structural complexity and range of the host plant. The scarcity of a large number of these species is primarily ascribed to a high seasonal turnover rate. Species diversity and numbers of individuals were found to vary between the different study sites and are attributed to the growth stage and condition of the host plant, as well as the effect of sun and shade on activity cycles and the choice of feeding levels.

Earthquakes on the south-west of Koryak highlands are connected with a block-key tectonics of lithosphere of marine transital of north-eastern margin of Eurasia and the block-key structure of its strata. The cloud of shocks of three strong earthquakes: Koryak`s (13.10.1988), Khailin`s (8.03.1991) and Olutor`s (20.04.2006) is located over the downfold of lithosphere bottom with drop of depths equal to 15-20 km. Preparation for the seismic events evolution to the north-eastward is possible.
