“…As a consequence of severe fire day-temperature rises, insolation increases and humidity decreases inside the forest (Parmeter 1977) and environmental conditions become much more extreme and unstable than in old, closed forests. Conditions in old-growth forests favour competitive fungal species (see Grime 1979, Pugh 1980, which seem to dislike environmental stress and disturbance (Cooke and Rayner 1984). In wood-rotting fungi competitive species are usually slow-growing and longliving (Pugh 1980, Cooke andRayner 1984) and prefer trees in later stages of decay succession in contrast to ruderal species (see Grime 1979, Pugh 1980, in which there seems to be more pioneer colonists (Rayner and Todd 1979).…”

“…For example, species growing in fire areas and in charred trunks must tolerate high temperatures (thermotolerant species; Cooke and Rayner 1984) and low water potential (xerotolerant species; Cooke and Rayner 1984). Pugh (1980) called species which can live in high stress and high disturbance circumstances as "escapers", and the proportion of escapers should also increase in burned forests in contrast to competitors.…”

“…mycorrhizosphere effect, Linderman, 1988). However, few differences were noted among the microbial groups present in the experimental treatments, possibly due to airborne microbes that colonized the autoclaved soil (Katznelson & Richardson, 1943;Pugh, 1980). Because it was not our intent to grow plants under aseptic conditions, but rather to compare the growth of mycorrhizal and non-mycorrhizal plants in autoclaved soil, invasion of microbes into the autoclaved soil does not prevent the evaluation of the mycorrhizal response of little bluestem grass.…”

SUMMARYTo determine the response of little bluestem [Schisachyrium scoparium (Michx.) Nash] to vesicular-arbuscular mycorrhizal (VAM) fungi, various microbial populations, and interactions between VAM fungi and other microbes plants were grown m three substrates; autoclaved soil, autoclaved soil to which VAM fungal-free sievmgs of non-autoclaved soil were added, and non-autoclaved soil. Mycorrhizal plants were established in autoclaved soil and in autoclaved soil receiving sievings by using little bluestem root pieces that were Cloroxtreated for 9 or 17 s as a source of VAM fungal inoculum. Exposure of root pieces to a 05 "" solution of sodium hypochlorite (Clorox) for 13-23 s, surface-sterilizes the roots, but it does not destroy viable internal VAM fungi. Control plants were grown in substrates receiving autoclaved root pieces. Plants grown in the autoclaved substrates had greater total biomass than plants grown m non-autoclaved soil. Inoculum type (autoclaved or surface sterilized root pieces) or addition of sievings had no effect on any growth parameter for plants grown in autoclaved soil. Mycorrhizal plants grown m the autoclaved substrate, not receiving sievmgs had higher tissue concentrations of P, Ca, S, Zn, Mn, and Fe than non-mycorrhizal plants grown m the same substrate. However, mycorrhizal plants did not produce more biomass than non-mycorrhizal plants in autoclaved substrates. Differences observed between plants grown m the autoclaved and non-autoclaved substrates are most likely attributable to greater nutrient ava.lab.l.tv of autoclaved substrates. The type of inoculum used and sub.strate conditions had negligible effects on rhizoplane and soil microbial populations. These included rhizoplane fungi and bacteria and selected functional groups of rh.zoplane microbes (cellulose, ch.tin, and protein decomposers).

“…are of a particular ''functional type'') and that those from other environments will have different attributes and belong to other ''functional types'' (e.g. Grime, 1979;Pugh, 1980;Reich, Walters & Ellsworth, 1992). FIBS assumes that the key ecological processes operating on the vegetation can be identified simply from an analysis of the distribution of these various ''functional types''.…”
