Nematodes are microscopic worms belonging to the soil biota with high species diversity. Nematodes have different compositions in different types of soil and areas. This research is conduct to determine the presence and genus of soil nematodes found in mustard plantations in Landasan Ulin Utara Village, Banjarbaru, South Kalimantan. Soil samples are taken from community vegetable plantations with a depth of 0-20 cm around the mustard plant rhizosphere located in ??Jalan Kurnia and Jalan Sukamara, Landasan Ulin Utara Village, Banjarbaru. Extraction to separate nematodes from soil using the Whitehead & Hemming method (1965) and nematode fixation using the Seinhorst method (1959). Furthermore, the permanent nematode preparations were made for the identification stage by morphological observations and morphometric measurements. The identification results showed that the genera of nematodes found in the study site's soil samples were Iotonchus, Crustorhabditis, Ironus, and Xiphinema.

Wetlands in natural areas in South Africa have been described before, but no literature exists concerning the phyto­sociology of urban wetlands. The objective of this study was to conduct a complete vegetation analysis of the wetlands in the Potchefstroom Municipal Area. Using a numerical classification technique (TWINSPAN) as a first approximation, the classification was refined by using Braun-Blanquet procedures. The result is a phytosociological table from which a number of unique plant communities are recognised. These urban wetlands are characterised by a high species diversity, which is unusual for wetlands. Reasons for the high species diversity could be the different types of disturbances occurring in this area. Results of this study can be used to construact more sensible management practises for these wetlands.

The investigation of algal-mycological complexes in the Rybachy Peninsula soils was carried out. The different types of tundra soils (Al-Fe-humus podzols, podburs, dry-peaty, peats low moor, cryogenic, undeveloped soils) were researched. The soil samples were collected along the route from Bolshaya Volokovaya Bay, which is in the Barents Sea, to the west of the Cape Nemetskiy. The organic horizons of the tundra podzols and podburs on the Rybachy Peninsula are less acid in comparison with the continental tundra soils of the region. Number of microfungi in the Peninsula soils varied from 9 to 70 thousand colony-forming units per 1 g of soil (CFU/g). It was the least in the cryogenic soils. The fungal mycelium length was significant in all the soils with the exception of the undeveloped one – more than 1 thousand m in 1 g of soil. The biomass amounted to 1.7 mg/g of soil. The species diversity of the soil micromycetes complexes is represented by 12 species. The species Penicillium decumbens dominated by the abundance and frequency of occurrence in the podburs, dry-peaty soils, podzols and peats low moor soils. P. raistrickii and P. glabrum predominated in the undeveloped soils, while Mortierella stylospora prevailed in the cryogenic soils. 62 eukaryotic algae as well as 18 species of cyanobacteria were found in the soil samples from Peninsula. The cryogenic and undeveloped soils, as well as Al-Fe-humus podzols and podburs were characterized by low species diversity, predominantly of green algae of classes Chlorophyceae and Trebouxiophyceae. Cyanobacteria and diatoms were noted by their considerable diversity in the dry-peaty soils and peats low moor soils.

Starch Production

Sago (Metroxylon spp.) is the world’s highest starch producer that have high productivity. Sago starch, however, is still underutilized compared to other starch. Sago can produce dry starch of 20-40 ton per ha per year. Indonesia has the largest sago area in the world with more than 90% of the world’s total sago area. Sago have high species diversity and not all of them have the same starch-producing capability. This research was conducted to gather information on the morphological characters and starch production potentials of several types of sago in Meranti Islands Regency, Riau Province, Indonesia, especially in Bandul, Mengkirau, Tanjung Peranap, and Bagan Melibur. Three different types of sago in Kepulauan Meranti Regency, Riau, has been identified, namely Beremban, Meranti and Sangka. The morphology and starch production of different types of sago vary depending on environmental conditions, including soil types. Beremban Sago collected from Bandul Village were found to have the highest starch content, therefore it has potentials to be developed for starch production in Indonesia.

Abstract In different types of substrate (soil, litter, lichens and mosses) collected at three memorial complexes (cemeteries) of Kyiv (Ukraine), 70 species from 57 genera, 34 families of oribatid mites were found. A few eurytopic species capable of tolerance to different types of pollution make up an essential part in each species complex. The species diversity and complexity of oribatid community structure at researched areas increased with distance from the city center. There was no direct relation between the degree of dominance of most common species and the cemetery’s relative remoteness from the center of the city.
