ABSTRACT Unraveling how agricultural management practices affect soil biota network complexity and stability these changes relate to processes functions is critical for the development of sustainable agriculture. However, our understanding knowledge still remains unclear. Here, we explored effects intensity on complexity, stability, multifunctionality, as well relationships among factors. Four typical land use types representing a gradient disturbance were selected in calcareous red soils southwest China. The four with increasing included pasture, sugarcane farmland, rice paddy fields, maize cropland. cohesion, topological features (e.g., average degree, clustering coefficient, path length, diameter, graph density, modularity), variation degree used evaluate strength interactions between species, respectively. results showed that intensive increased species competition but decreased stability.

Incorporating viruses into soil ecology: A new dimension to understand biogeochemical cycling

Critical Reviews in Environmental Science and Technology, Journal Year: 2023, Volume and Issue: 54(2), P. 117 - 137

Published: June 16, 2023

Viruses, with an estimated abundance of 1031 on Earth, are important component soil ecosystems. As obligate parasites that entirely depend hosts for reproduction and survival, viruses have been linked to microbial community diversity metabolic activities in soil. Emerging evidence indicates influence a broad-spectrum processes sustain biodiversity, biogeochemical cycling, fertility, plant health. Research is its early stages. Even observational assessments viral ecology such as abundance, diversity, distribution, life strategies, ecological relevance, functions, only just beginning be revealed. In this review, we summarize the state knowledge concerning potential function(s) how they likely composition, nutrient cycles, carbon dynamics example. major drivers mortality functioning across wide range spatial temporal scales, appear key regulators cellular metabolism properties well critical ecosystem function. We conclude indispensable demanding further investigation. Defining abiotic interactions within environment, revealing virus-host interaction networks, elucidating roles cycling but few many aspects worthy future A more complete view participation food webs face changing climate will lead improved management services environmental sustainability.

Ice nucleation catalyzed by the photosynthesis enzyme RuBisCO and other abundant biomolecules

Communications Earth & Environment, Journal Year: 2023, Volume and Issue: 4(1)

Published: Feb. 25, 2023

Abstract Atmospheric aerosol and the cloud droplets ice crystals that grow on them remain major sources of uncertainty in global climate models. A subset aerosol, nucleating particles, catalyze freezing water at temperatures warmer than −38 °C. Here we show RuBisCO, one most abundant proteins plants phytoplankton, is efficient known immersion particles with a mean temperature −7.9 ± 0.3 Further, demonstrate RuBisCO present ambient continental where it can serve as an particle. Other biogenic molecules act range −19 to −26 In addition, our results indicate heat denaturation not universal indicator proteinaceous origin suggesting current studies may fail accurately quantify biological particle concentrations their importance.

Effect of Aggregation and Molecular Size on the Ice Nucleation Efficiency of Proteins

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(10), P. 4594 - 4605

Published: Feb. 26, 2024

Aerosol acts as ice-nucleating particles (INPs) by catalyzing the formation of ice crystals in clouds at temperatures above homogeneous nucleation threshold (-38 °C). In this study, we show that immersion mode efficiency environmentally relevant protein, ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO), occurs between -6.8 and -31.6 °C. Further, suggest range is controlled RuBisCO concentration protein aggregation. The warmest median temperature (-7.9 ± 0.8 °C) was associated with highest (2 × 10

Environmental Galenics: large-scale fortification of extant microbiomes with engineered bioremediation agents

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2022, Volume and Issue: 377(1857)

Published: June 27, 2022

Contemporary synthetic biology-based biotechnologies are generating tools and strategies for reprogramming genomes specific purposes, including improvement and/or creation of microbial processes tackling climate change. While such activities typically work well at a laboratory or bioreactor scale, the challenge their extensive delivery to multiple spatio-temporal dimensions has hardly been tackled thus far. This state affairs creates research niche what could be called Environmental Galenics (EG), i.e. science technology releasing designed biological agents into deteriorated ecosystems sake safe effective recovery. Such endeavour asks not just an optimal performance activity stake, but also material form formulation agents, propagation interplay with physico-chemical scenario where they expected perform. EG encompasses adopting available physical carriers microorganisms channels horizontal gene transfer as potential paths spreading beneficial through environmental microbiomes. some these propositions may sound unsettling anti-genetically modified organisms sensitivities, fall under tag TINA (there is no alternative) technologies in cases mere reduction emissions will help revitalization irreversibly lost ecosystems. article part theme issue ‘Ecological complexity biosphere: next 30 years’.

Eukaryotic algae in the top few centimeters of fellfield soils ice-free Maritime Antarctica have many important effects on their habitat, such as being significant drivers organic matter input into and reducing impact wind erosion by soil aggregate formation. To better understand diversity distribution Antarctic terrestrial algae, we performed a pilot study surface Meseta, an plateau mountain crest Fildes Peninsula, King George Island, hardly influenced marine realm anthropogenic disturbances. It is openly exposed to microbial colonization from outside connected much harsher dryer zones continental Antarctic. A temperate reference site under mild land use, SchF, was included further test for Meseta contrasting environment. We employed paired-end metabarcoding analysis based amplicons highly variable nuclear-encoded ITS2 rDNA region, complemented clone library approach. targeted four algal classes, Chlorophyceae, Trebouxiophyceae, Ulvophyceae, Xanthophyceae, representing key groups cold-adapted algae. surprisingly high 830 OTUs revealed, assigned 58 genera classes. Members green class Trebouxiophyceae predominated communities. The major part biodiversity, 86.1% all OTUs, could not be identified at species level due insufficient representation sequence databases. classes Ulvophyceae Xanthophyceae exhibited most unknown diversity. About 9% shared with that Germany. In small portion which assessed, entire identity references shows likely wide beyond Polar regions. They probably originated propagule banks far southern regions, transported aeolian transport over long distances. dynamics severity environmental conditions surface, determined currents, algae's adaptability harsh may account similarity communities between northern parts Meseta.
