A sand dune area in Santa Catarina, Brazil, was surveyed every 3 months to determine species composition and seasonal variation of arbuscular mycorrhizal fungi populations associated with Spartina ciliata. Spores from 12 fungal species were recovered. Overall species richness was 5.9. A plot of rank versus abundance provided an indirect measure of the structure of the fungal community and showed a linear relationship among species. A mean of 298 spores/100 g soil were extracted from sand dune samples, with Acaulospora scrobiculata forming 50.9% of the total population. The most frequently recovered species at all sampling dates were Gigaspora albida, Scutellospora weresubiae, A. scrobiculata, and one undescribed Scutellospora species. Spore abundance ranged from 0 to 69 spores/100 g soil for all species except A. scrobiculata (60–247 spores/100 g). Spore abundance of each species did not vary significantly through the season. However, several general trends were observed. The number of spores of Glomus constrictum, Glomus etunicatum, and Acaulospora sp. (No. 2) was maximal in winter, whereas that of Gigaspora albida peaked in spring. Species composition and richness of arbuscular fungi in Brazilian dunes appear to be similar to those in sand dunes along the Atlantic coast of the United States. Key words: arbuscular mycorrhizal fungi, ecology, sand dunes, spore populations, Brazil.

In the year 2003, the occurrence of arbuscular mycorrhizal fungi (AMF) of the phylum <i>Glomeromycota</i> in cultivated and uncultivated soils of the Lubuskie province was investigated. The occurrence of AMF was examined based on 56 root and rhizosphere soils collected under 7 species of cultivated and uncultivated plants growing in 28 localities. Spores of AMF were isolated from both field-collected samples and trap cultures. They were revealed in 100% of field soils and 93.8% of trap cultures and represented 7 of the 8 recognized genera of the <i>Glomeromycota</i>. The arbuscular fungi occurring distinctly more frequently in the soil and root samples examined were members of the genus <i>Glomus</i>. The species of AMF most frequently occurring in cultivated soils of the Lubuskie province were <i>G. claroideum</i>, <i>G. constrictum</i>, <i>G. deserticola</i> and <i>G. mosseae</i>, whereas <i>G. claroideum</i>, <i>G. constrictum</i>, <i>G. deserticola</i>, <i>G. mosseae</i>, and <i>S. dipurpurescens</i> were more frequently found in uncultivated sites. The analysis of similarity of the species composition of AMF populations in sites of the Lubuskie province and the Western Pomeranian province earlier examined showed that (1) the occurrence in Poland of most taxa of these fungi detected in the study presented here is even and does not change with time, (2) the communities of AMF area are stable, despite the arduousness resulting from the agricultural and chemical practices conducted, and (3) the species diversity of the plants cultivated in a long period of time has no influence on the species composition of populations of AMF.

155 rhizosphere soil and root mixtures were collected from under <em>Ammophila arenaria </em>colonizing maritime dunes of the island Bornholm (Denmark) to determine arbuscular mycorrhizal fungi (AMF) of the phylum Glomeromycota co-existing with this plant. In the laboratory, each mixture was divided into two parts. One part was used to establish a pot culture with <em>Plantago lanceolata</em> as the host plant to initiate sporulation of fungi that had not produced spores in field conditions. In the second part, the numerical and species composition of the spore populations of AMF sporulating in the field was determined. Spores of AMF were found in 70 field-collected samples and 134 trap cultures. They represented 26 species and six undescribed morphotypes in six genera of the Glomeromycota. Of them, 20 species and three morphotypes in five genera occurred in the field, and 16 species and three morphotypes in five genera were found in trap cultures. The fungi most frequently revealed were members of the genus <em>Glomus</em>; a total of 17 species and six morphotypes of this genus were recognized. Considering the occurrence of spores in both field samples and trap cultures, the fungi most frequently co-occurring with roots of <em>A. arenaria </em>growing in the dunes of Bornholm were <em>G. irregulare </em>(present in 73.6% of samples), followed by <em>Scutellospora dipurpurescens </em>(19.4%) and <em>Archaeospora trappei </em>(10.3%). However, <em>Glomus irregulare </em>mainly sporulated in trap cultures; spores of this fungus were found in only 0.6% of field samples. Other relatively frequently found species were <em>G. aggregatum </em>(9.0%), <em>G. eburneum </em>(7.1%), <em>Paraglomus laccatum </em>(5.2%), and <em>S. armeniaca </em>(6.5%). The species most abundantly sporulating in the field were <em>G. aggregatum </em>(produced 28.36% of all spores isolated), <em>G. badium</em> (11.00%), and <em>S. dipurpurescens </em>(21.55%).
