ntroductionThe practice of Global North (i.e., "richer" globalized countries located in the northern hemisphere, except for Australia and New Zealand) researchers making roundtrips to South "poorer" developing around tropics Southern hemisphere) collect materials then process, analyze, publish results with little no involvement from local collaborators is referred as "helicopter research" or "parachute [1].At best, scientists provide logistical help knowledge community, such field site...
Fungal community composition often shifts in response to warmer temperatures, which might influence decomposition of recalcitrant carbon (C). We hypothesized that evolutionary trade-offs would enable C-using taxa respond more positively warming than labile taxa. Accordingly, we performed a experiment an Alaskan boreal forest and examined changes the prevalence fungal In complementary field trial, characterized ability use C (glucose), intermediate (hemicellulose or cellulose), (lignin). also...
Abstract The magnitude and direction of carbon cycle feedbacks under climate warming remain uncertain due to insufficient knowledge about the temperature sensitivities soil microbial processes. Enzymatic rates could increase at higher temperatures, but this response change over time if microbes adapt warming. We used Arrhenius relationship, biochemical transition state theory, thermal physiology theory predict responses extracellular enzyme V max K m temperature. Based on these concepts, we...
Humans are inextricably linked to each other and our natural world, microorganisms lie at the nexus of those interactions. Microorganisms form genetically flexible, taxonomically diverse, biochemically rich communities, i.e., microbiomes that integral health development macroorganisms, societies, ecosystems.
Fungi play fundamental ecological roles in terrestrial ecosystems. However, their distribution and diversity remain poorly described natural communities, particularly arid semi-arid In order to identify environmental factors determining fungal community structure these systems, we assessed conjunction with soil physicochemical characteristics a ecosystem Baja California, Mexico, endemic for Coccidioidomycosis (Valley Fever). Two different microhabitats, burrows (influenced by rodent...
Abstract Background Short-term experiments have indicated that warmer temperatures can alter fungal biomass production and CO 2 respiration, with potential consequences for soil C storage. However, we know little about the capacity of fungi to adapt warming in ways may dynamics. Thus, exposed Neurospora discreta moderately warm (16 °C) (28 selective 1500 mitotic generations, then examined changes mycelial growth rate, biomass, spore production, respiration. We tested hypothesis strains will...
Earth’s temperature is rising, and with this increase, fungal communities are responding affecting soil carbon processes. At a long-term soil-warming experiment in boreal forest interior Alaska, warming alters the function of microbes, thus, decomposition carbon. But what genetic mechanisms resource allocation strategies behind these community shifts changes? Here, we evaluate efforts under experimental using metatranscriptomics. We profiled toward cell metabolic maintenance, characterized...
Over the long term, soil carbon (C) storage is partly determined by decomposition rate of that slow to decompose (i.e., recalcitrant C). According thermodynamic theory, rates C might differ from those non-recalcitrant in their sensitivities global warming. We decomposed leaf litter a warming experiment Alaskan boreal forest, and measured mass loss (lignin) vs. (cellulose, hemicellulose, sugars) throughout 16 months. found these fractions responded differently Specifically, after one year...
Abstract Fungi are mediators of the nitrogen and carbon cycles in terrestrial ecosystems. Examining how uptake organic matter decomposition potential differs fungi can provide insight into underlying mechanisms driving fungal ecological processes ecosystem functioning. In this study, we assessed frequency genes encoding for specific enzymes that facilitate 879 genomes with taxa grouped trait-based categories. Our linked gene-trait data approach revealed gene frequencies vary across within...
Coccidioides immitis and C. posadasii are closely related fungal pathogens that cause coccidioidomycosis, a respiratory disease also known as Valley fever. In general, regarded to grow in arid semi-arid soils North South America. If person inhales these spores, they can become sick with The soil properties conducive for the presence of not currently well defined, including whether there differences each species. Recent efforts, especially over last decade, collect samples positive now...
ABSTRACT The effect of warming on anti‐microbial resistance (AMR) genes in the environment has critical implications for public health but is little studied. We collected published soil bacterial genomes from BV‐BRC database and tested correlation between reported optimal growth temperature number encoded AMR genes. Furthermore, we relationship gene transcription a natural ecosystem by analysing transcriptomes manipulation experiment an Alaskan boreal forest. hypothesised that there positive...
Soil microbial communities, including biological soil crust microbiomes, play key roles in water, carbon and nitrogen cycling, weathering, other nutrient releasing processes of desert ecosystems. However, our knowledge distribution patterns ecological drivers is still poor, especially so for the Chihuahuan Desert. This project investigated effects trampling disturbance on surface explored community composition structure, related to abiotic biotic landscape characteristics within Desert...
Abstract. To make predictions about the carbon cycling consequences of rising global surface temperatures, Earth system scientists rely on mathematical soil biogeochemical models (SBMs). However, it is not clear which have better predictive accuracy, and a rigorous quantitative approach for comparing validating has yet to be established. In this study, we present Bayesian SBM comparison that can incorporated into statistical model selection framework. We compared fits linear nonlinear SBMs...
Biogenic volatile organic compounds (VOCs) play crucial roles in ecosystems at multiple scales, ranging from mediating soil microbial interactions to contributing atmospheric chemistry. However, VOCs and how they respond environmental change remains understudied. We aimed assess 2 abiotic global drivers, warming simulated nitrogen (N) deposition, impact VOC emissions over time a temperate forest. characterized the effect of warming, N their interaction on composition during growing season...
Rising to meet global, interconnected challenges, such as food security and ecosystem resilience global change, requires insights from across the Earth. This is especially true for belowground terrestrial ecological processes. Soil ecologists have answered this call: like mushrooms, large datasets databases on soil physics, chemistry ecology are sprouting up everywhere (e.g. Fine-Root Ecology Database (Iversen et al., 2018), FunFun (Zanne 2020), GlobalFungi (Větrovský COntinuous SOil...
