Significance Human activities have resulted in large increases the availability of nutrients terrestrial ecosystems worldwide. Although plant community responses to elevated been well studied, soil microbial remain poorly understood, despite their critical importance ecosystem functioning. Using DNA-sequencing approaches, we assessed response communities experimentally added nitrogen and phosphorus at 25 grassland sites across globe. Our results demonstrate that composition these shifts consistent ways with nutrient inputs there are corresponding ecological attributes members. This study represents an important step forward for understanding connection between inputs, communities, altered

Microbial Surface Colonization and Biofilm Development in Marine Environments

Microbiology and Molecular Biology Reviews, Год журнала: 2015, Номер 80(1), С. 91 - 138

Biotic and abiotic surfaces in marine waters are rapidly colonized by microorganisms. Surface colonization subsequent biofilm formation development provide numerous advantages to these organisms support critical ecological biogeochemical functions the changing environment. Microbial surface association also contributes deleterious effects such as biofouling, biocorrosion, persistence transmission of harmful or pathogenic microorganisms their genetic determinants. The processes mechanisms well key players among surface-associated microbiota have been studied for several decades. Accumulating evidence indicates that specific cell-surface, cell-cell, interpopulation interactions shape composition, structure, spatiotemporal dynamics, microbial communities. Several mechanisms, including (i) surface, population, community sensing signaling, (ii) intraspecies interspecies communication interaction, (iii) regulatory balance between cooperation competition, identified lifestyle. In this review, recent progress study is synthesized discussed. Major gaps our knowledge remain. We pose questions targeted investigation surface-specific community-level features, answers which would advance understanding ecology communities at levels from molecular mechanistic details through systems biological integration.

Soil Fungal:Bacterial Ratios Are Linked to Altered Carbon Cycling

Frontiers in Microbiology, Год журнала: 2016, Номер 7

Опубликована: Авг. 8, 2016

Despite several lines of observational evidence, there is a lack consensus on whether higher fungal:bacterial (F:B) ratios directly cause soil carbon (C) storage. We employed RNA sequencing, protein profiling and isotope tracer techniques to evaluate differing F:B are associated with differences in C A mesocosm 13C labeled foliar litter decomposition experiment was performed two soils that were similar their physico-chemical properties but differed microbial community structure, specifically ratio (determined by PLFA analyses, sequencing profiling; all three corroborating each other). Following addition, we observed consistent increase abundance fungal phyla; greater increases the dominated soil; implicating role fungi decomposition. Litter derived respired CO2 consistently lower, residual bulk SOM high demonstrating storage potential soil. conclude this system, increased both altered cycling patterns highlight significant indicate linked potential.

A New Analysis of Mars “Special Regions”: Findings of the Second MEPAG Special Regions Science Analysis Group (SR-SAG2)

Astrobiology, Год журнала: 2014, Номер 14(11), С. 887 - 968

Опубликована: Ноя. 1, 2014

A committee of the Mars Exploration Program Analysis Group (MEPAG) has reviewed and updated description Special Regions on as places where terrestrial organisms might replicate (per COSPAR Planetary Protection Policy). This review update was conducted by an international team (SR-SAG2) drawn from both biological science exploration communities, focused understanding when could occur. The study applied recently available data about martian environments organisms, building a previous analysis (2006) undertaken similar team. Since then, new body highly relevant information been generated Reconnaissance Orbiter (launched in 2005) Phoenix (2007) Express twin Rovers (all 2003). Results have also gleaned Science Laboratory 2011). In addition to data, there is considerable regarding known environmental limits life Earth-including potential for microbial survive under conditions. SR-SAG2 included examination models natural variation water activity temperature; reconsideration current parameters used define Regions; maps descriptions recommended treatment "Uncertain" or "Special" features those potentially formed influence future landed spacecraft. Significant changes our knowledge capabilities existence possibly habitable led appreciation may be identified protected. SR-SAG considered impact human missions Mars, locations resources that should not inadvertently contaminated activity.

Insights into the ecology, evolution, and metabolism of the widespread Woesearchaeotal lineages

Microbiome, Год журнала: 2018, Номер 6(1)

Опубликована: Июнь 8, 2018

As a recently discovered member of the DPANN superphylum, Woesearchaeota account for wide diversity 16S rRNA gene sequences, but their ecology, evolution, and metabolism remain largely unknown. Here, we assembled 133 global clone libraries/studies 19 publicly available genomes to profile these patterns Woesearchaeota. Phylogenetic analysis shows high with 26 proposed subgroups this archaeal phylum, which are widely distributed in different biotopes primarily inland anoxic environments. Ecological ancestor state reconstruction specific reveal that oxic status environments is key factor driving distribution evolutionary A selective an adaptive colonization from can be supported by evidence presence ferredoxin-dependent pathways only not biotopes. Metabolic reconstructions support anaerobic heterotrophic lifestyle conspicuous metabolic deficiencies, suggesting requirement complementarity other microbes. Both lineage abundance co-occurrence network analyses across diverse confirmed complementation revealed potential syntrophic relationship between methanogens, modeling. If correct, may impact methanogenesis ecosystems. The findings provide ecological framework at scale indicate roles, especially methanogenesis.
