Quadrats (1×1 m) were placed at each end of the transect, at the field boundary, and 2.15–2.50 m into the Nardo-Galion grassland. The composition of fungal species present in a grassland soil may have important implications for plant biodiversity and ecosystem variability [42], while ecosystem stability may be particularly affected if application of inputs to managed pastures is suspended. Soil fungal richness increased with plant species richness and mean annual precipitation. Campbell Multivariate ANOVA followed by Bonferroni's t-test (P≤0.05 probability level) was used to determine significant differences in the presence of individual TRFs between positions across the transect. F (2007) Differences in the species composition of arbuscular mycorrhizal fungi in spore, root and soil communities in a grassland ecosystem. Although mean ribotype number as determined from TRFLP data (Table 1) was not significantly different across the transect between U4a and MG7b, Jaccard analysis of both fragment length and DGGE data (Table 3) indicated that the composition of soil fungal communities across the transect was quite different. This chapter elaborates the classification and characteristics of fungi and eukaryotic algae along with the ecological roles of these groups in soil. (, Kaufman Wernars Davies It was also noticeable that certain dominant ribotypes were location specific across the transect. We are grateful to Nabla Kennedy, Deirdre Gleeson, Sue Lynch and three anonymous reviewers for helpful comments on the manuscript. Briefly, at one part of the site an area of Lolio-Plantaginion grassland (MG7b type within the UK National Vegetation Classification [1]) had been enclosed, this was a product of ploughing and reseeding in 1993. Bardgett The practices of liming, fertilisation, increased grazing and reseeding lead to diminished floristic diversity, with a shift from semi-natural species-rich grasslands to species-poor plant communities dominated principally by perennial ryegrass (Lolium perenne) and white clover (Trifolium repens).

The purified PCR product was then digested enzymatically and analysed using an automated sequencer as described previously [25]. (, Oxford University Press is a department of the University of Oxford. G Ungulate and topographic control of arbuscular mycorrhizal fungal spore community composition in a temperate grassland. Fungal community composition was resilient to direct fire effects, most likely because grassland fires transfer little heat to the soil. Following this, the samples were cooled to 4°C in a refrigerator for 20 min. Forney There were no significant (P>0.05) differences in mean numbers of TRFs between sample sites across the transect between U4a and MG7b soils (Table 1), with mean ribotype numbers detected ranging between 13 and 17. A constitutive, host-specific symbiosis exists between the aboveground fungal endophyte Epichloë coenophiala (Morgan-Jones & W. Gams) and the cool-season grass tall fescue (Lolium arundinaceum (Schreb.) For this reason, cloning approaches have largely been superseded by community fingerprinting when alterations in microbial community structure are being monitored. Google Scholar. For example, U4a soil produced six TRFs which accounted for more than 10% of the relative abundance, Transitional 1 produced three TRFs accounting for 10% each while Transitional 2 and MG7b only produced one or two TRFs respectively which accounted for 10% or more of the relative abundance. The value of a TRFLP approach is that it may be interpreted on a number of levels. This area has been limed at approximately 5 t ha−1 and fertilised at a rate of approximately 150 kg N, 25 kg P and 50 kg K ha−1, annually. Fig. This describes the similarity of each sample pair based only on DGGE bands or TRFs present in one or both communities. Cheng This revealed that three TRFs (578, 130 and 634) did not correspond to any sequences present in the database; TRF568 matched to two species of Kionochaeta (Sordariales); TRF573 matched to Kluyveromyces lactis; TRF565 matched to 23 members of the Basidiomycota (6% Ceratobasidiales/Cantharellales, 20% Stereales, 27% Hymenomycetidae and 47% Agaricales); and TRF563 also matched 23 species, mostly members of the Basidiomycota (6% Hymenomycetidae, 6% Agaricales, 78% Tremellales) but also matching 10% Taphrinales (Ascomycota). The aim of this work was to assess whether reductions in fungal biomass reported as a consequence of agricultural improvement correspond to alterations in fungal community structure. They are commonly found on prairies and decompose grass and leaves. E The answer, perhaps surprisingly, is probably yes. U.B It is often perceived that high plant diversity should promote a richly diverse microbial community due to the formation of intimate relationships between specific plant species and microorganisms, and conversely low plant diversity should be associated with reduced microbial diversity. Temperate grasslands are widely distributed across the Eurasian continent, known as “the Eurasian steppes”, connecting West and East Europe, Central Asia, China, South Asia, and the Middle East 31. Secondly, fragment lengths can potentially be compared with known sequences in a database or clone library (identification of ribotypes); while fragment peak height provides information about the relative abundance of a ribotype within a particular soil sample. Klironomos Parkin For this purpose we considered ribotypes with percentage abundances above or around 10% as dominant. Crossref. 30, No. R.D 1). Furthermore, we performed an independent pairwise comparison between fertilized and unfertilized grasslands in Belgium and Iceland to compare results. The samples were then centrifuged at 3000×g for 3 min to separate the pentane layer from the soil. The Shannon–Weaver diversity index also indicated a change in community diversity based on TRFLP data, although fungal diversity did not decrease with decreasing floristic diversity.

Hill Triplicate samples were pooled for each position across the transect and 15 μl of this mixture was analysed by DGGE using a polyacrylamide gel (10%) with a gradient of 30–45% denaturants (100% denaturant is equivalent to 7 M urea and 40% v/v of de-ionised formamide). (, Haack One interesting result of soil improvement was a reduction in co-dominant fungal ribotypes, with communities in transitional areas (particularly Transitional area 2) and MG7b being dominated by fewer ribotypes. Where C=2.3, N=sum of peak heights in a given TRFLP profile, ni=height of TRF i and i=number of TRFs in each TRFLP profile. While temperatures are often extreme in some grasslands, the average temperatures are about -20°C to 30°C. When the seven most abundant TRFs from U4a soil were compared to the database three TRFs (578, 130 and 634) did not correspond to any sequences present. Eoin Brodie, Suzanne Edwards, Nicholas Clipson, Soil fungal community structure in a temperate upland grassland soil, FEMS Microbiology Ecology, Volume 45, Issue 2, July 2003, Pages 105–114, https://doi.org/10.1016/S0168-6496(03)00126-0. Karlen (, Ranjard Fungal community diversity (Shannon–Weaver index) as estimated from TRFLP profiles was significantly (P<0.05) lower in soil from the Transitional 2 area than in any other position across the transect (Table 1). Tropical grasslands have dry and wet seasons that remain warm all the time. J.N [4] demonstrated that fertilisation reduced the ratio of fungal to bacterial phospholipid fatty acids (PLFAs) in a permanent pasture. Bardgett ), which is a common forage grass in the United States, Australia, New Zealand, and temperate European grasslands. reading for all who are involved in land management for nature conservation, The pentane layer was removed and transferred to a new tube. The zone of floristic transition (transect) between the two grasslands was sampled across three transects 10 m in length, 12 m apart. A notable component of this zone was a progressive reduction in grassland species number in the order U4a>Transitional 1>Transitional 2>MG7b. R.D This zone was characterised by four main areas, the climax grasslands (U4a and MG7b) and the transitional areas (1 and 2). T I Jaccard analysis indicated substantial differences in ribotypes between fungal communities across the transect, with the TRFLP-based approach showing the lower similarity values (Table 3) compared to DGGE. For this approach a slightly different bead beating-based DNA extraction procedure was employed. Dighton Temperate grasslands have a temperate continental climate, which is cooler than savannas. The selection of photographs was expanded for many species by adding or substituting new photographs, particularly focusing on photos helpful for identification. S.J DNA was amplified by a nested PCR procedure [17]. Stackebrandt In principle, combining these parameters builds a view of fungal community structure. Lata C.T We thank the Roche family at Longhill for kind permission to carry out field work on their land, Terry Marsh for providing the 18S rRNA database subset, Martin Moelhoff for assistance with PatScan. This is dependent upon the availability of a well developed fungal sequence database which, with the necessary software, could generate a restriction fragment list specific to primers and restriction enzymes used. across the British Isles. Boller Moutoglis Floristic analysis of the climax grasslands indicated Agrostis capillaris, Galium saxatile, Potentilla erecta and Rhytidiadelphus squarrosus occurring at 100% frequency and Festuca ovina at 80% in the Nardo-Galion (U4a) grassland, with L. perenne, Poa trivialis and T. repens all occurring at 100% frequency in the Lolio-Plantaginion (MG7b) grassland. P.F All statistical analyses were carried out using the computer package SPSS v.11.0 (SPSS Inc., IL, USA). Arbuscular mycorrhizal fungi. All soil DNA samples were then subjected to a final filtration purification step using a High Pure™ PCR product clean up kit. DGGE is relatively insensitive with less abundant ribotypes tending not to form distinct bands but contributing to a diffuse background, or structurally different DNA molecules coincidentally co-migrating to the same place on a gel [39]. The highest degree of variability within fungal communities was also found in this transitional area, with 84% of ribotypes only being detected in one of three replicates. R (, Smit Mawdsley [...] This is a well-produced and much-needed guide to grassland fungi that should be useful to beginners as well as to more experienced feld mycologists. Floristic analysis of the climax grasslands indicated Agrostis capillaris, Galium saxatile, Potentilla erecta and Rhytidiadelphus squarrosus occurring at 100% frequency and Festuca ovina at 80% in the Nardo-Galion (U4a) grassland, with L. perenne, Poa trivialis and T. repens all occurring at 100% frequency in the Lolio-Plantaginion (MG7b) grassland. C.T Using the PatScan program (http://www-unix.mcs.anl.gov/compbio/PatScan/HTML/getting_scan_for_matches.html), this database was scanned in order to determine the relative positions of primer and restriction enzyme recognition sites. Culture-based analyses, such as plate counts, selective enrichment, or baiting (for in situ isolation of fungi), only profile the limited culturable proportion of the fungal community, whereas the other techniques provide little insight into fungal community structure. Shah T Department of Industrial Microbiology, University College Dublin, Belfield, Dublin 4, Ireland. Glandorf (, Ruzicka Selectivity and functional diversity in arbuscular mycorrhizas of co-occurring fungi and plants from a temperate deciduous woodland. TRFs can potentially be used to indicate phylogenetic associations, which can be used to propose putative species identity. (, van der Heijden Weimken These practices are also known to affect the microbial component of soil communities, with fertiliser or lime applications typically resulting in increased bacterial numbers, decreased fungal biomass, and changes in microbial functional properties [3–6]. In acidic upland grasslands, fungi have been shown to be major components of soil microbial biomass [4], contributing significantly to nutrient and organic turnover processes including proteolysis, phosphorus mobilisation and translocation [7–9]. Liesack Numbers of TRFs and diversity measurements of fungal ribotypes in soil at positions across a transect between U4a and MG7b grasslands. H These findings give new insight into dominant plant species shifts in degraded semiarid grasslands. This corresponded to our previous study of bacterial community dynamics, and a TRFLP analysis of micro-eukaryotes in activated sludge [28]. While this web-based program is not currently linked to eukaryotic databases the authors were able to use a subset of near complete sequences extracted from the eukaryotic small subunit ribosomal database and perform simulated digestions. A number of techniques have been used to assess soil fungal communities including culture-based approaches, direct microscopy of soil hyphae [10,11], fatty acid analysis [12,13] and membrane sterol quantification [14,15]. These approaches are dependent upon the successful extraction and purification of environmental nucleic acids from soil, together with PCR amplification linked either to a clone sequence-based analysis or a community fingerprinting technique. Nazaret O 218 124) at an altitude of 300 m above sea level on a peaty podzolic soil formed over granite/quartzite bedrock, with an annual rainfall between 2000 and 2800 mm, and is described in detail elsewhere [25].

(, Marsh To provide supporting evidence for TRFLP analysis of fungal communities across the transect, a comparison was made using DGGE performed on the same soil samples, albeit with a nucleic acid extraction procedure that differed slightly. M.G.A Palojarvi (, Donnison Various names of temperate grasslands include pampas, downs, and veldts. 90: 371 – 384. Published by Elsevier Science B.V. All rights reserved. Temperate grasslands have warm, humid summers with an average temperature of 18° C and cool, dry winters with an average temperature of 10° C. Most of the rain falls as convection rain in the summer and sometimes frost and snow may occur in the winter. Temperate grasslands are areas of open grassy plains that are sparsely populated with trees. (, Miller S.K L.J The Eurasian steppe is one of the largest temperate grasslands and play an important role in the global C and N cycles. Farris Typical large mammals include the blue wildebeest, American bison, giant anteater, and Przewalski's horse. N The question is this: will it be as useful nationally as it is for the Wye Valley? (, Brodie Rodwell K L P T.M G.S Liu Ergosterol was detected with a UV detector set at 282 nm. W.T W.A L The primer sequence and the MspI recognition sequence were successfully pattern-matched to 1477 sequences in the database. This may have important implications for ecosystem stability or productivity, particularly if agricultural inputs to managed grasslands are suspended. G.S Although fungal biomass was reduced towards MG7b, both TRFLP and DGGE data indicated that position within the transect (and hence the environmental parameters operating at that position) did not reduce fungal ribotype number (diversity). E (, Lukow Mawdsley In addition to breaking down nutrients, it also has a symbiotic relationship with plants that help those plants absorb nutrients. The vital role of fungi in the ecology of grasslands is becoming more widely appreciated, sparking an increasing interest in identification. Mycorrhizae is another fungus found in grasslands. R.J van Elsas Increased soil pH has been shown to influence levels of fungal biomass although varied responses have been reported [34,35]; likewise nitrogen applications have been implicated in both increased and decreased fungal biomass [5,36,37]. Agricultural management affects communities of culturable root-endophytic fungi in temperate grasslands By E. M. Wilberforce, Lynne Boddy, R. Griffiths and Gareth W. Griffith Cite Before polymerisation was complete a 3-ml top loading gel containing 0% denaturants was dispensed and the gel comb carefully placed into this. L [16–20]), but have not yet been applied to the fungal communities of upland grasslands. Detectable ribotype numbers determined by DGGE (13–18) were approximately half those detected by TRFLP (23–33). As such it would be beneficial to have some information regarding the components of a soil fungal community in the absence of agricultural treatments and subsequently monitor the impact of treatments on individual community members. D A (, Ranjard Across the transect (towards MG7b) there was a substantial reduction in plant diversity (25 species reducing to six), together with a marked increase in pH (pH 3.9 to 6.3), phosphorus and nitrate; conversely there was a substantial decline in soil ammonium levels [25]. M.J DGGE data and pooled TRFLP data were converted to binary format and compared using the Jaccard coefficient (Sj) [31]. Fornet Lilburn DGGE profiles of fungal communities in soil at positions across a transect between U4a and MG7b grasslands. G.J Poly For this study we developed a sensitive approach to monitor soil fungal community structure based on soil nucleic acid extraction and TRFLP analysis, which to our knowledge is one of the first reported uses of this approach in grassland fungal ecology. T.L Clearly this was not the case in this grassland, with reductions in plant diversity having no significant effect on fungal ribotype number. H Griffith Clipson 5, 2012, p. … Plant growth is possible when temperatures are warm enough and when ample water is available to sustain it, which typically occurs in the spring, summer, and fall. Relative abundance (%) of fungal TRFs in soil at positions across a transect between U4a and MG7b grasslands. Firstly, the number of TRFs or ribotypes found in each soil gives information regarding fungal diversity at a quantitative level (numbers of ribotypes present). I D.L We sampled soils of calcareous and acidic grasslands and roots of 34 host plant species across a large geographical gradient of atmospheric nitrogen deposition and soil phosphorus availability. P.A As such, DGGE bands or TRFs that are not present in either of two communities being compared do not contribute to the similarity of the two communities. Grasslands receive about 500 to 950 mm of rain per year compared to deserts, which receive less than 300 mm and tropical forests, which receive more than 2,000 mm. This may reflect the dominance of culturable industrial and medically important species in such databases. Our results indicate AM fungi and defoliation jointly suppress S. krylovii biomass; however, prolonged defoliation weakens mycorrhizal influence on plant community composition. Bead beating was performed at 4500 rpm using a Minibeadbeater (BioSpec Products Inc., OK, USA) twice for 30 s with cooling on ice for 1 min between beating cycles. In effect the transect or gradient at this site permitted us to follow community alterations on a spatial scale without the confounding environmental parameters associated with temporal studies. T.G The diverse soils of temperate and tropical agriculture, grasslands, forests, arctic and alpine tundra, and even deserts also harbor a surprisingly diverse and active flora of both eukaryotic algae and cyanobacteria. J After extraction and purification of total DNA from soil, a portion of the eukaryotic 18S small subunit rRNA gene specific to fungi was amplified using primer set nu-SSU-0817-5′ (5′-TTAGCATGGAATAATRRAATAGGA-3′) and nu-SSU-1536-3′ (5′-ATTAGCAATGCYCTATCCCCA-3′) [19].
