Microbial diversity drives multifunctionality in terrestrial ecosystems

Nature Communications, Год журнала: 2016, Номер 7(1)

Abstract Despite the importance of microbial communities for ecosystem services and human welfare, relationship between diversity multiple functions (that is, multifunctionality) at global scale has yet to be evaluated. Here we use two independent, large-scale databases with contrasting geographic coverage (from 78 drylands from 179 locations across Scotland, respectively), report that soil positively relates multifunctionality in terrestrial ecosystems. The direct positive effects were maintained even when accounting simultaneously drivers (climate, abiotic factors spatial predictors). Our findings provide empirical evidence any loss will likely reduce multifunctionality, negatively impacting provision such as climate regulation, fertility food fibre production by

A global atlas of the dominant bacteria found in soil

Science, Год журнала: 2018, Номер 359(6373), С. 320 - 325

Опубликована: Янв. 18, 2018

The immense diversity of soil bacterial communities has stymied efforts to characterize individual taxa and document their global distributions. We analyzed soils from 237 locations across six continents found that only 2% phylotypes (~500 phylotypes) consistently accounted for almost half the worldwide. Despite overwhelming communities, relatively few are abundant in globally. clustered these dominant into ecological groups build first atlas taxa. Our study narrows down number a "most wanted" list will be fruitful targets genomic cultivation-based aimed at improving our understanding microbes contributions ecosystem functioning.

Scientists’ warning to humanity: microorganisms and climate change

Nature Reviews Microbiology, Год журнала: 2019, Номер 17(9), С. 569 - 586

In the Anthropocene, in which we now live, climate change is impacting most life on Earth. Microorganisms support existence of all higher trophic forms. To understand how humans and other forms Earth (including those are yet to discover) can withstand anthropogenic change, it vital incorporate knowledge microbial 'unseen majority'. We must learn not just microorganisms affect production consumption greenhouse gases) but also they will be affected by human activities. This Consensus Statement documents central role global importance biology. It puts humanity notice that impact depend heavily responses microorganisms, essential for achieving an environmentally sustainable future. The majority with share often goes unnoticed despite underlying major biogeochemical cycles food webs, thereby taking a key change. highlights microbiology issues call action microbiologists.

The global soil community and its influence on biogeochemistry

Science, Год журнала: 2019, Номер 365(6455)

Опубликована: Авг. 23, 2019

Soil organisms represent the most biologically diverse community on land and govern turnover of largest organic matter pool in terrestrial biosphere. The highly complex nature these communities at local scales has traditionally obscured efforts to identify unifying patterns global soil biodiversity biogeochemistry. As a result, environmental covariates have generally been used as proxy variation activity biogeochemical models. Yet over past decade, broad-scale studies begun see this heterogeneity biomass, diversity, composition certain groups across globe. These provide new insights into fundamental distribution dynamics land.

Global ecosystem thresholds driven by aridity

Science, Год журнала: 2020, Номер 367(6479), С. 787 - 790

Опубликована: Фев. 14, 2020

Aridity, which is increasing worldwide because of climate change, affects the structure and functioning dryland ecosystems. Whether aridification leads to gradual (versus abrupt) systemic specific) ecosystem changes largely unknown. We investigated how 20 structural functional attributes respond aridity in global drylands. Aridification led abrupt multiple attributes. These occurred sequentially three phases characterized by decays plant productivity, soil fertility, cover richness at values 0.54, 0.7, 0.8, respectively. More than 20% terrestrial surface will cross one or several these thresholds 2100, calls for immediate actions minimize negative impacts on essential services more 2 billion people living

High-level classification of the Fungi and a tool for evolutionary ecological analyses

Fungal Diversity, Год журнала: 2018, Номер 90(1), С. 135 - 159

Опубликована: Май 1, 2018

High-throughput sequencing studies generate vast amounts of taxonomic data. Evolutionary ecological hypotheses the recovered taxa and Species Hypotheses are difficult to test due problems with alignments lack a phylogenetic backbone. We propose an updated phylum- class-level fungal classification accounting for monophyly divergence time so that main ranks more informative. Based on phylogenies estimates, we adopt phylum rank Aphelidiomycota, Basidiobolomycota, Calcarisporiellomycota, Glomeromycota, Entomophthoromycota, Entorrhizomycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota Olpidiomycota. accept nine subkingdoms accommodate these 18 phyla. consider kingdom Nucleariae (phyla Nuclearida Fonticulida) as sister group Fungi. also introduce perl script newick-formatted backbone assigning into hierarchical framework, using this or any other system. provide example testing evolutionary based global soil data set.

A few Ascomycota taxa dominate soil fungal communities worldwide

Nature Communications, Год журнала: 2019, Номер 10(1)

Опубликована: Май 30, 2019

Despite having key functions in terrestrial ecosystems, information on the dominant soil fungi and their ecological preferences at global scale is lacking. To fill this knowledge gap, we surveyed 235 soils from across globe. Our findings indicate that 83 phylotypes (<0.1% of retrieved fungi), mostly belonging to wind dispersed, generalist Ascomycota, dominate globally. We identify patterns drivers fungal taxa occurrence, present a map distribution worldwide. Whole-genome comparisons with less dominant, point significantly higher number genes related stress-tolerance resource uptake fungi, suggesting they might be better colonising wide range environments. constitute major advance our understanding ecology have implications for development strategies preserve them ecosystem provide.

Erosion reduces soil microbial diversity, network complexity and multifunctionality

The ISME Journal, Год журнала: 2021, Номер 15(8), С. 2474 - 2489

Опубликована: Март 12, 2021

Abstract While soil erosion drives land degradation, the impact of on microbial communities and multiple functions remains unclear. This hinders our ability to assess true ecosystem services restore eroded environments. Here we examined effect at two sites with contrasting texture climates. Eroded plots had lower network complexity, fewer taxa, associations among relative non-eroded plots. Soil also shifted community composition, decreased abundances dominant phyla such as Proteobacteria, Bacteroidetes, Gemmatimonadetes. In contrast, led an increase in some bacterial families involved N cycling, Acetobacteraceae Beijerinckiaceae. Changes microbiota characteristics were strongly related erosion-induced changes multifunctionality. Together, these results demonstrate that has a significant negative diversity functionality.
