Leaf-cutting ants interact naturally with a range of antagonistic microorganisms, among them the soil-borne fungus Syncephalastrum. The antagonism of this fungus to the leaf-cutting ants’ fungal cultivar has been shown in studies without the ant queens. So far, the impacts of this fungus on whole colonies (queenright) of leaf-cutting ants are unknown. We assessed the impacts of Syncephalastrum on queenless

Carbon allocation mediated by arbuscular mycorrhizal fungi alters the soil microbial community under various phosphorus levels Fungal Ecol. (IF 2.9) Pub Date : 2023-02-13 Hong Huang, Shijun Liu, Yong Du, Jianjun Tang, Liangliang Hu, Xin Chen
Studies have shown that arbuscular mycorrhizal fungi (AMF) can shape the rhizosphere microbial community of the host plant, but the underlying mechanisms are unclear. Here, we tested the hypotheses that AMF may affect the rhizosphere microbial community by mediating carbon (C) allocation of the host plant, and that this mediation may be modulated by the soil phosphorus (P) level. Using a split-root

The impact of polyphenolic compounds on the in vitro growth of oak-associated foliar endophytic and saprotrophic fungi Fungal Ecol. (IF 2.9) Pub Date : 2023-02-12 Megan N. Nickerson, Lillian P. Moore, Jana M. U'Ren
Foliar fungal endophytes are horizontally transmitted symbionts that inhabit healthy, photosynthetic tissues of all lineages of land plants where they influence plant health and productivity. Endophyte communities often are more similar among closely related hosts, potentially as a result of a preference for particular morphological, ecophysiological, or chemical host traits. However, the various ecological

Non-invasive monitoring of photosynthetic activity and water content in forest lichens by spectral reflectance data and RGB colors from photographs Fungal Ecol. (IF 2.9) Pub Date : 2023-01-30 Michaela Bednaříková, Yngvar Gauslaa, Knut Asbjørn Solhaug
There is a need for non-invasive monitoring of temporal and spatial variation in hydration and photosynthetic activity of red-listed poikilohydric autotrophs. Here, we simultaneously recorded kinetics in RGB-colors (photos), reflectance spectra, water content, maximal (FV/FM), and effective quantum yield of PSII (ΦPSII) during desiccation in foliose lichens differing in cortical characteristics and

Host identity affects the response of mycorrhizal fungal communities to high severity fires in Alaskan boreal forests Fungal Ecol. (IF 2.9) Pub Date : 2023-01-20 M. Rae DeVan, Jill F. Johnstone, Michelle C. Mack, Teresa N. Hollingsworth, D. Lee Taylor
Ongoing climate change in the boreal forests of western North America is associated with wildfires which are increasing in extent and severity, thus impacting mycorrhizal fungal communities through fungal mortality and shifts in host species and age. We planted three native tree species, Picea mariana, Picea glauca, and Populous tremuloides, and non-native Pinus contorta var. latifolia at 22 post-fire
