Study Sites

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.

Ultimate Objective

The establishment of the Mapungubwe National Park has been an objective of several conservationists for many years. The ultimate objective is that this park should become a major component of a Transfrontier National Park shared by Botswana, Zimbabwe and South Africa. The aim of this study was to identify, classify and describe the plant communities present in the Ib land type of the park. Sampling was done by means of the Braun-Blanquet method. A total of 48 stratified random relevés were sampled in the Ib land type. All relevé data were imported into a TURBOVEG database, after which the numerical classification technique TWINSPAN was used as a first approximation. Subsequently, Braun-Blanquet procedures were used to refine data and a phytosociological table was constructed, using the visual editor, MEGATAB. Two plant communities and several subcommunities and variants were identified and described from the phytosociological table.

Intensity Of Invasion

The frequency and abundance of invasive alien woody plants were recorded along roadsides and at watercourse crossings in 87% (152/175) of the quarter degree squares in the study area. The survey yielded BO species of which the most prominent species (in order of prominence) in roadside and veld habitats were:  Chromolaena odoruta, Solatium mauritianum, Psidium guajava, Rubus spp., Acacia meamsu and Lantana camara The most prominent species (in order of prominence) in streambank habitats were:  Acacia dealbata, A. meamsii and  Salix babylonica.The greatest intensity of invasion was recorded in the Natal midlands and in the coastal belt of southern Natal, including the metropolitan areas of Pietermaritzburg and Durban. There was relatively little invasion in the north-eastern lowlands of Natal but the potential for expansion is great. Little invasion was recorded in the north-eastern Orange Free State except along some watercourses.

Low Altitude

An analysis of the vegetation of the relatively low altitude regions of the North-eastern Mountain Sourveld of the eastern Transvaal escarpment is presented. Releves were compiled in 53 stratified random sample plots. ATWINSPAN-classification, refined by Braun-Blanquet procedures, revealed seven plant communities. In the hierarchical classification one class, one alliance, four associations, four subassociations and two valiants are recognised. Formal syntaxonomic descriptions of the syntaxa are given. All communities are related to specific environmental conditions, of which geology, aspect, altitude and rockiness of the soil surface are the most important.

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.

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.

Grassland Biome

The proposed Highveld National Park (HNP) is an area of high conservation value in South Africa, covering approximately 0.03% of the endangered Grassland Biome. The park is situated immediately adjacent to the town of Potchefstroom in the North-West Province. The objective of this study was to identify, classify, describe and map the plant communities in this park. Vegetation sampling was done by means of the Braun-Blanquet method and a total of 88 stratified random relevés were sampled. A numerical classification technique (TWINSPAN) was used and the results were refined by Braun-Blanquet procedures. The final results of the classification procedure were presented in the form of phytosociological tables and, thereafter, nine plant communities were described and mapped. A detrended correspondence analysis confirmed the presence of three structural vegetation units, namely woodland, shrubland and grassland. Differences in floristic composition in the three vegetation units were found to be influenced by environmental factors, such as surface rockiness and altitude. Incidences of harvesting trees for fuel, uncontrolled fires and overgrazing were found to have a significant effect on floristic and structural composition in the HNP. The ecological interpretation derived from this study can therefore be used as a tool for environmental planning and management of this grassland area.Conservation implications: Grasslands are amongst the most threatened and least conserved vegetation biomes in South Africa, with less than 1.3% currently being conserved. The HNP has significant value for biodiversity conservation and the protection of this area will contribute to the preservation of the highly threatened Highveld vegetation types.

Two new haemogregarine species, Hepatozoon langii n. sp. and Hepatozoon vacuolatus n. sp., are described from the pe-ripheral blood of the high altitude crag lizard, Pseudocordylus langi, collected between October 2006 and April 2009 from the North Eastern Drakensberg, Eastern Free State. Hepatozoon langii n. sp. has maturing and mature gamonts that appear encapsulated and have narrow, curved tails. Their cytoplasm stains pinkish-purple with Giemsa, while their nuclei are pur-ple stained with stranded chromatin. Mature gamonts measure 19.1 ± 1.0 (15.4–28.1) μm long by 6.2 ± 1.1 (3.5–7.9) μm wide. Hepatozoon vacuolatus n. sp. gamonts are mostly broader at one pole than the other, have bluish-pink cytoplasm characterised by distinctive rounded and oval vacuoles, and demonstrate pink granules with Giemsa staining. Nuclei stain purple and are mainly coarsely granular. Mature gamonts measure 16.5 ± 1.0 (14.7 - 17.6) μm long by 5.9 ± 1.2 (4.0 - 7.7) μm wide. Both species parasitize erythroblasts, as well as erythrocytes and can dehaemoglobinize the cytoplasm of their host cells. Hepatozoon langii n. sp occurred in the absence of H. vacuolatus n. sp., but the latter haemogregarine always formed mixed infections with the former; no stages intermediate between the two haemogregarine types were observed.
