Underlying Mechanisms

Mycorrhizae are ubiquitous in terrestrial ecosystems. With an increasing awareness that this symbiotic association plays important roles in plant population dynamics, community structures and ecosystem functioning, mycorrhizal ecology has emerged as a fast growing subdiscipline in the field of ecology. Over recent decades, studies have expanded from descriptions of basic mycorrhizal biology to investigations of their functional relevance in a broader ecological context. Today’s research is dominated by the search for underlying mechanisms and general principles. The readings on issues related to mycorrhizal ecology include basic overviews of mycorrhizal studies, classification and species diversity, methodology in mycorrhizal examination, costs and benefits, population and community ecology of mycorrhizae, their ecological significance in plant community and ecosystem, multitrophic interactions, and practical applications. This bibliography focuses on the most widespread and ecologically important types of mycorrhizae—arbuscular mycorrhizae and ectomycorrhizae.

Speed Of Analysis

The three biggest advances in fungal molecular phylogenetics in the last few years have been (1) the huge expansion in data sets, (2) the development of nonribosomal loci for phylogenetic analysis, and (3) the use of increasingly sophisticated types of analyses. In addition, advances in parallel computing hold great promise for dramatic increases in speed of analysis. These changes have had, or will have, a direct impact on mycorrhizal ecology through the use of sequence-based identification and an indirect impact through the conclusions drawn from such studies. One problem in the field has been the accidental addition of erroneous sequences to the public databases through a variety of means, including polymerase change reaction contamination. We discuss several examples, suggest ways to identify errors, and argue the case for third-party annotations of sequences. Multiple studies have produced compelling evidence that the ectomycorrhizal habit has developed convergently in multiple lineages of fungi and plants. We reexamine the case for loss of the ectomycorrhizal habit in fungi and show that the results are model dependent.Key words: internal transcribed spacer (ITS) region, peroxidase genes, likelihood models, erroneous data, ectomycorrhizal habit.

Fire in a prairie significantly affected subsequent vesicular–arbuscular mycorrhizal (VAM) fungal colonization and sporulation, plant aboveground production, and tissue inorganic nutrient concentration. Colonization levels of VAM fungi in little bluestem (Schizachyrium scoparium (Michx.) Nash) roots were significantly (p < 0.05) lower on the burned site than on the unburned site during the first growing season postburn, but there were no significant differences between sites during the 2nd year. On each sampling date during the first growing season postburn, the burned site had significantly higher aboveground production than the unburned site. Significantly higher tissue levels of available K, Ca, and Mg were found on the unburned site than on the burned site; however, when nutrients were expressed in terms of nutrients in tissue per square metre, there were no significant differences between the burned and unburned sites. Spore counts for soil collected from the rhizosphere of little bluestem and randomly on burned and unburned sand prairies decreased from May into summer and then increased in late summer and fall on both sites during the first growing season postburn. Rhizosphere spore numbers were significantly lower on the burned site than on the unburned site in May and June, but they were significantly higher on the burned site in October during the first growing season. The results suggest that the response of VAM fungi to fire may be attributable to changes in the host plant and not due to any direct effect of fire.

The majority of terrestrial plants associate with fungi in symbiotic resource-exchange relationships called mycorrhizae. Because of the importance of these mycorrhizal systems to ecosystem functioning, it is crucial that future resource managers and scientists have a solid understanding of mycorrhizal ecology. Limited interest of postsecondary students in plants and fungi compared with animals, combined with difficulties visualizing below-ground processes, present challenges for learning mycorrhizal concepts. To address this, we created the digital, plant-ecology-centric, action-based game Shroomroot for use in a second year, postsecondary Introduction to Soil Science course. We then assessed effects of Shroomroot on students’ knowledge acquisition and engagement with the topic of mycorrhizal ecology using a pre- and post-test evaluation. Students’ knowledge of mycorrhizal ecology increased significantly after playing Shroomroot, and tended to increase more for items related to Shroomroot gameplay than in rewards-based game content. Student engagement with mycorrhizal content tended to increase after gameplay. These results suggest positive potential for action-based, plant-ecology-oriented digital games in a postsecondary science curriculum. Furthermore, greater understanding of mycorrhizae has the potential to improve our multifaceted relationships with the ecosystems upon which we depend.
