“…However, we first need empirical measurements of mycorrhizal fungal traits, which can be difficult because of limitations in fungal cultivation (particularly for arbuscular mycorrhizal (AM) fungi), measurement of traits in situ and accounting for phenotypic plasticity (Behm & Kiers, ). Despite these difficulties, myriad physiological, chemical, morphological and physical traits have been measured (Chagnon et al ., ; Chaudhary et al ., ). We emphasize that a key goal in the next decade of MEF research should be the development of a unified approach for the quantification of mycorrhizal fungal traits, which would facilitate the establishment of a global database of the type used successfully by plant ecologists (i.e.…”

Yet, the nature of mycorrhizal fungal diversity–ecosystem function (MEF) relationships for both genotypes and species is currently poorly defined. New experiments should reflect the richness of genotypes and species in nature, but we still lack information about the extent to which fungal populations in particular are structured. Sampling designs should quantify the diversity of mycorrhizal fungal genotypes and species at three key broad spatial scales (root fragment, root system and interacting root systems) in order to inform manipulation experiments and to test how mycorrhizal fungal diversity both responds, and confers resilience to, environmental drivers.

“…AM fungi can indirectly affect ecosystems via their effects on individual plants, which then propagate to the level of an ecosystem function. Data on the range of effects pertaining to individual hosts have been broadly synthesized (Hoeksema et al ., ; see database: Chaudhary et al ., ). The fungi can also indirectly influence functioning by affecting plant or microbial community composition, both of which represent ecosystem properties that, in themselves, can affect functioning.…”

Several studies have demonstrated the potential for variation in AM fungal diversity to also affect ecosystem functioning, mainly via effects on primary productivity. Diversity in these studies is usually characterized in terms of the number of species, unique evolutionary lineages or complementary mycorrhizal traits, as well as the ability of plants to discriminate among AM fungi in space and time. However, the emergent outcomes of these relationships are usually indirect, and thus context dependent, and difficult to predict with certainty. Here, we advocate a fungal‐centric view of AM fungal biodiversity–ecosystem function relationships that focuses on the direct and specific links between AM fungal fitness and consequences for their roles in ecosystems, especially highlighting functional diversity in hyphal resource economics. We conclude by arguing that an understanding of AM fungal functional diversity is fundamental to determine whether AM fungi have a role in the exploitation of marginal/novel environments (whether past, present or future) and highlight avenues for future research.

“…We propose that the CO 2 fertilization effect be quantified based on mycorrhizal type and soil nitrogen status, and that large-scale ecosystem models incorporate mycorrhizal types to account for the differences in biomass enhancement by eCO 2 . Mycorrhizae are ubiquitous, and sort predictably with plant functional type (24,34), making feasible their inclusion in models to capture this microbial influence on global biogeochemistry. Accounting for the influence of mycorrhizae will improve representation of the CO 2 fertilization effect in vegetation models, critical for projecting ecosystem responses and feedbacks to climate change.…”

Plants buffer increasing atmospheric CO 2 concentrations through enhanced growth, but the question whether nitrogen availability constrains the magnitude of this ecosystem service remains unresolved. Synthesizing experiments from around the world, we show that CO 2 fertilization is best explained by a simple interaction between nitrogen availability and mycorrhizal association. Plant species that associate with ectomycorrhizal fungi show a strong biomass increase (30 ± 3%, P<0.001) in response to elevated CO 2 regardless of nitrogen availability, whereas low nitrogen availability limits CO 2 fertilization (0 ± 5%, P=0.946) in plants that associate with arbuscular mycorrhizal fungi. The incorporation of mycorrhizae in global carbon cycle models is feasible, and crucial if we are to accurately project ecosystem responses and feedbacks to climate change.One Sentence Summary: Only plants that associate with ectomycorrhizal fungi can overcome nitrogen limitation, and thus take full advantage of the CO 2 fertilization effect. Main Text:Terrestrial ecosystems sequester annually about a quarter of anthropogenic CO 2 emissions (1), slowing climate change. Will this effect persist? Two contradictory hypotheses have been offered: the first is that CO 2 will continue to enhance plant growth, partially mitigating anthropogenic CO 2 emissions (1, 2), while the second is that nitrogen (N) availability will limit the CO 2 fertilization effect (3, 4), reducing future CO 2 uptake by the terrestrial biosphere (5-7). Plants experimentally exposed to elevated levels of CO 2 (eCO 2 ) show a range of responses in biomass, from large and persistent (8, 9) to transient (6), to non-existent (10), leaving the question of CO 2 fertilization open. Differences might be driven by different levels of plant N availability across experiments (11), but N availability alone cannot explain contrasting results based on available evidence (7,12).
