“…Despite intensified interest in understanding the link between above-and belowground biodiversity and the implications that this link may have for ecosystem functioning [2,11,23,40], few studies have examined the relationship between plant diversity and soil microbial communities using culture-independent techniques; the results from the few that have are equivocal [8,9,58,61]. For example, Broughton and Gross [9] examined microbial fatty acid methyl esters (FAMEs) along a topographic gradient in a mid-successional temperate grassland that varied in plant diversity (from 2 to 16 species) and productivity.…”

“…Differences in plant communities can directly affect soil microbial communities through variations in the type, complexity, and amount of organic matter input to soils. Plant characteristics (e.g., rooting depth and density, canopy cover) also vary and can indirectly affect microbes via changes in the soil environment (e.g., soil moisture, temperature, and pH [1,23]). Changes in any of these factors can influence physical and metabolic niche diversity in the soil, and therefore may affect microbial diversity or composition.…”

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

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.

“…In soils, they mediate nutrient cycling, organic matter decomposition, soil aggregate formation, soil carbon storage (Zinn et al, 2002), and have an impact on composition of plant communities (Hooper et al, 2000;Wardle, 2002) and plant disease prevention and bio-control (Kennedy, 1998;Biró et al, 2000;Artursonn, et al, 2006). The microbial community composition and functioning can be influenced by exudates from roots and litter quality and quantity.…”

Abstract. Eucalyptus camaldulensis has been the main exotic species planted in reforestation programs in the tropics due to its fast growth and adaptability to climate variations. Based on the premise that the conversion from natural grazed pastures to commercial Eucalyptus plantations generates significant changes in soil properties, we assessed the impact of this exotic plantation on soil chemical and biological indicators. The study was conducted in 6 plantations across Senegal following a decreasing rainfall gradient from south to north. The plantations were divided in three lots according to their age: young plantations (established in 2003, 6 years old); intermediate plantations (established in 1998, 11 years old) and old plantations (established in 1982 and 1983, 26 years old). Our results clearly showed that E. camaldulensis plants significantly modified soil pH and soil bacterial community at all sites regardless of the age of the plantation. Microbial biomass (assessed by substrate-induced respiration), community structure (assessed by denaturing gradient gel electrophoresis profiles) and function (assessed by Catabolic Response Profile using different substrates) were all significantly decreased. The acidifying effect of E. camaldulensis, the effect of high level of polyphenols and their impact on microbial communities and ecosystem functioning were discussed.

“…Belowground consumers include both organisms that interact directly with plant roots (pathogens, root herbivores, mycorrhizal fungi, symbiotic bacteria) and indirectly with plants (i.e., saprophytic bacteria and fungi that mineralize nutrients and maintain plant nutrition) as well as their predators. The interaction between plants and aboveground and belowground consumers is critical for driving ecosystem functioning both aboveground and belowground (Hooper et al 2000;Wardle 2002;Eisenhauer 2012). It is well recognized that within trophic groups, species differ in their effects on other organisms and ecosystem processes as a consequence of their fundamental attributes or traits.…”

Forest ecosystems world-wide are being subjected to invasion by organisms representing all domains of life. Here we use a combined aboveground-belowground approach to provide a conceptual framework for assessing how forests respond to biological invasions. We first address mechanisms by which invasive plants and aboveground and belowground consumers impact on forests, and highlight that although we have a growing understanding of the determinants of the effects of invasive plants, for invasive consumers we have yet to move from a series of iconic case studies to the development of general principles. We also address the effects of invasive biota in the context of the drivers of invasion, coinvasion and invasional meltdown, the issue of simultaneous species gains and losses, and forest restoration and recovery post-invasion. We then highlight areas that would benefit from further work, particularly regarding underlying mechanisms, determinants of context-dependency of invader effects, and linkages between causes and consequences of invasion. In concluding, we emphasize that biological invaders have the potential for largescale and long-term impacts on forest processes, and consideration of these impacts in an abovegroundbelowground context will enable better prediction of future responses of forests to invaders and their management as well as of restoration efforts.
