Contrasting effects of above and belowground litter inputs in shaping the soil microbiome worldwideNARA Subscribed
Background and aims Microbes are the primary decomposers of litter, yet how above and belowground litter inputs contribute to soil microbial structure and function remains unclear across global environmental gradients. Methods Here, we conducted a global meta-analysis including 1,509 observations to explore the global patterns of how leaf addition, leaf removal, root removal, and both leaf and root removal affect structure and...
Motivation Arbuscular mycorrhizal (AM) fungi are central to plant nutrient acquisition, soil carbon dynamics, and ecosystem resilience. Yet, their biogeography remains incompletely characterised, particularly across underrepresented regions. Australia, with its characteristic ecological conditions, continental scale, and long‐standing evolutionary trajectories, has been notably undersampled. This gap hinders our ability to mak...
Evaluating the Usefulness of the C‐S‐R Framework for Understanding AM Fungal Responses to Climate Change in AgroecosystemsNARA Subscribed
Arbuscular mycorrhizal (AM) fungi play a key role in terrestrial ecosystems by forming symbiotic relationships with plants and may confer benefits for sustainable agriculture, by reducing reliance on harmful fertiliser and pesticide inputs and enhancing plant resilience against insect herbivores. Despite their ecological importance, critical gaps in understanding AM fungal ecology limit predictions of their responses to global...
Fire shapes fungal guild diversity and composition through direct and indirect pathwaysNARA Subscribed
Fire has shaped global ecosystems for millennia by directly killing organisms and indirectly altering habitats and resources. All terrestrial ecosystems, including fire‐prone ecosystems, rely on soil‐inhabiting fungi, where they play vital roles in ecological processes. Yet our understanding of how fire regimes influence soil fungi remains limited and our knowledge of these interactions in semiarid landscapes is virtually abse...
Silicon accumulation suppresses arbuscular mycorrhizal fungal colonisation in the model grass Brachypodium distachyonNARA Subscribed
Purpose Silicon (Si) accumulation by grasses alleviates diverse biotic and abiotic stresses. Despite this important functional role, we have limited understanding of how root microbial symbionts, such as arbuscular mycorrhizal (AM) fungi, affect Si uptake and even less about how Si supply and accumulation affect AM fungal colonisation. Our objective was to determine the nature of this two–way interaction in the model grass, Br...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
Targeted plant defense: silicon conserves hormonal defense signaling impacting chewing but not fluid‐feeding herbivoresNARA Subscribed
Plants deploy an arsenal of chemical and physical defenses against arthropod herbivores, but it may be most cost efficient to produce these only when attacked. Herbivory activates complex signaling pathways involving several phytohormones, including jasmonic acid (JA), which regulate production of defensive compounds. The Poaceae also have the capacity to take up large amounts of silicon (Si), which accumulates in plant tissue...
