“…Differences in genetic composition and diversity may suggest distinct selective environments among the locations. Although associated plant species have been shown to alter the structure of the soil microbial community [23,34,41], percent cover and plant species composition did not vary significantly among the sampling locations in this study (A.L. Davelos and L.L.…”

Spatial Variation in Streptomyces Genetic Composition and Diversity in a Prairie Soil

et al. 2004

Understanding how microbial genotypes are arrayed in space is crucial for identifying local factors that may influence the spatial distribution of genetic diversity. In this study we investigated variation in 16S rDNA sequences and rep-PCR fingerprints of Streptomyces stains isolated from prairie soil among three locations and four soil depths. Substantial variation in Streptomyces OTU (operational taxonomic unit) and BOX-PCR fingerprint diversity was found among locations within a limited spatial area (1 m 2 ). Further, phylogenetic lineages at each location were distinct. However, there was little variation in genetic diversity among isolates from different soil depths and similar phylogenetic lineages were found at each depth. Some clones were found at a localized scale while other clones had a relatively widespread distribution. There was poor correspondence between 16S rDNA groupings and rep-PCR fingerprint groupings. The finding of distinct phylogenetic lineages and the variation in spatial distribution of clones suggests that selection pressures may vary over the soil landscape.

“…In this study, we determined changes in fungal community structure as reported by the fingerprints of fungal ITS sequences, and used the diversity index (H, S) to evaluate the soil fungal community diversity, as reported by the diversity indices obtained [3]. The present study demonstrates that the diversity and abundance of soil fungal community from different ages of Korean pine forest first increased and then decreased with Korean pine growth, probably reflecting the difference of vegetation type and age [21,24].…”

The polymorphisms of soil fungal rDNA Internal Transcribed Spacer regions were studied in Korean pine forests of various ages (10-100-year-old trees) by means of cloned libraries, and analyzed to determine the effects of the trees' developmental stage on soil fungal community structure. The obtained Shannon diversity index (H) and richness (S) indicated that the diversity of the soil fungal community increased significantly with the development of Korean pines (P \ 0.05). In addition, cluster analysis (UPGMA) showed that the soil fungal community variety associated with differently aged Korean pines was higher than 50 %. The soil fungal community diversity correlated significantly with the N content and C/N ratio of the soil (P \ 0.05). The results of this study indicate that the age of in Korean pine can affect soil fungal community by altering soil properties, which in turn could affect the nutrient cycling in the forest ecosystem.

“…Although the detection of individual species is not possible with this method, phospholipid analyses allow one to investigate changes in broad microbial groups, such as fungi, bacteria, and actinomycetes [54]. Microbial ecologists have begun to apply these techniques to understanding the links between above-and belowground diversity [19,30,58].…”

“…Similarly, recent work suggests that microbial community composition can be affected by plant species or even different cultivars of the same species in agricultural systems [3,4,30]. Few studies, however, have examined how microbial communities change in response to plant diversity using culture-independent techniques [58,61].…”

The Influence of Tropical Plant Diversity and Composition on Soil Microbial Communities

2006

There is growing interest in understanding the linkages between above-and belowground communities, and very little is known about these linkages in tropical systems. Using an experimental site at La Selva Biological Station, Costa Rica, we examined whether plant diversity, plant community composition, and season influenced microbial communities. We also determined whether soil characteristics were related to differences in microbial communities. Phospholipid fatty acid (PLFA) composition revealed that microbial community composition differed across a plant diversity gradient (plots contained 1, 3, 5, or over 25 species). Plant species identity also was a factor influencing microbial community composition; PLFA composition significantly varied among monocultures, and among three-species combinations that differed in plant species composition. Differences among treatments within each of these comparisons were apparent in all four sampling dates of the study. There was no consistent shift in microbial community composition between wet and dry seasons, although we did see significant changes over time. Of all measured soil characteristics, soil C/N was most often associated with changes in microbial community composition across treatment groups. Our findings provide evidence for human alteration of soil microbial communities via the alteration of plant community composition and diversity and that such changes are mediated in part by changes in soil carbon quality.
