Abstract The incredibly complex soil microbial communities at small scales make their analysis and identification of reasons for the observed structures challenging. Microbial community structure is mainly a result inoculum (dispersal), selective advantages those organisms under habitat‐based environmental attributes, ability colonizers to sustain themselves over time. Since protective, its inhabitants have long adapted varied conditions, significant portions are likely stable. Hence, substantial portion will not correlate often measured attributes. We suggest that drivers be ranked on basis importance fundamental needs microbes: (i) supply energy, i.e., organic carbon electron acceptors; (ii) effectors or stressors, pH, salt, drought, toxic chemicals; (iii) macro‐organism associations, plants seasonality, animals fecal matter, fauna; (iv) nutrients, in order, N, P, probably lesser importance, other micronutrients, metals. relevance also varies with spatial time scales, example, aggregate field regional, persistent dynamic populations transcripts, extent phylogenetic difference, hence phenotypic differences organismal groups. present summary matrix provide guidance which important particular studies, special emphasis wide range temporal illustrate this genomic population (rRNA gene) data from selected studies.

Early-life environmental effects on birds: epigenetics and microbiome as mechanisms underlying long-lasting phenotypic changes

Journal of Experimental Biology, Journal Year: 2024, Volume and Issue: 227(Suppl_1)

Published: March 7, 2024

ABSTRACT Although the long-lasting effects of variation in early-life environment have been well documented across organisms, underlying causal mechanisms are only recently starting to be unraveled. Yet understanding can help us predict how organisms will respond changing environments. Birds offer a great system which study developmental plasticity and its owing production large external eggs trajectories, combined with long tradition applied, physiological, ecological evolutionary research. Epigenetic changes (such as DNA methylation) suggested key mechanism mediating taxa. More recently, gut microbiome identified another potential mediator plasticity. As first step whether these contribute birds, this Review summarizes (both prenatal postnatal) influence epigenetic markers microbiome. The literature shows both biotic resources social environment) abiotic (thermal various anthropogenic stressors) factors modify yet data concerning many other environmental limited. links modifications lasting phenotypic still scarce, but hypothalamic–pituitary–adrenal axis one putative pathway. This identifies several knowledge gaps, including on long-term effects, stability molecular changes, lack diversity systems studied, provides directions for future

Inhibition of the p62-Nrf2-GPX4 Pathway Confers Sensitivity to Butachlor-Induced Splenic Macrophage Ferroptosis

Journal of Agricultural and Food Chemistry, Journal Year: 2024, Volume and Issue: 72(30), P. 16998 - 17007

Published: July 17, 2024

Butachlor is widely used in agriculture around the world and therefore poses environmental public health hazards due to persistent poor biodegradability. Ferroptosis a type of iron-mediated cell death controlled by glutathione (GSH) GPX4 inhibition. P62 an essential autophagy adaptor that regulates Keap1 activate nuclear factor erythroid 2-related 2 (Nrf2), which effectively suppresses lipid peroxidation, thereby relieving ferroptosis. Here, we found butachlor caused changes splenic macrophage structure, especially impaired mitochondrial morphology with disordered suggestive occurrence This was further confirmed detection iron metabolism, GSH system, peroxidation. Mechanistically, suppressed protein level p62 promoted Keap1-mediated degradation Nrf2, results decreased expression accelerated These findings suggest targeting p62-Nrf2-GPX4 signaling axis may be promising strategy for treating inflammatory diseases.

Glyphosate and a glyphosate-based herbicide affect bumblebee gut microbiota

FEMS Microbiology Ecology, Journal Year: 2023, Volume and Issue: 99(7)

Published: June 14, 2023

Pollinator decline is one of the gravest challenges facing world today, and overuse pesticides may be among its causes. Here, we studied whether glyphosate, world's most widely used pesticide, affects bumblebee gut microbiota. We exposed diet to glyphosate a glyphosate-based herbicide quantified microbiota community shifts using 16S rRNA gene sequencing. Furthermore, estimated potential sensitivity bee microbes based on previously reported presence target enzyme. Glyphosate increased, whereas decreased diversity, indicating that negative effects are attributable co-formulants. Both treatments significantly relative abundance potentially glyphosate-sensitive bacterial species Snodgrasella alvi. However, Candidatus Schmidhempelia genera increased in bumblebees treated with glyphosate. Overall, 50% detected were classified as resistant while 36% sensitive. Healthy core have been shown protect bees from parasite infections, change metabolism, decrease mortality. Thus, heavy use herbicides implications ecosystems.

Seasonal and habitat dependence of plant species, functional and phylogenetic diversity in agricultural landscapes

Ecological Indicators, Journal Year: 2024, Volume and Issue: 160, P. 111795 - 111795

Published: Feb. 26, 2024

The biodiversity of agricultural landscapes is under significant threat, while non-agricultural habitats within these play a crucial role in conservation. There has been limited investigation into how plant species, functional and phylogenetic diversity varies across different seasons landscapes. Thus, we carried out survey the communities China's lower Yellow River plain. We investigated features functionality, phylogeny, species. compared differences community structure using non-metric multidimensional scaling analysis tested signal methods. Our characteristics revealed between habitats, with season having more impact. levels functional, followed seasonal pattern, spring seeing highest values autumn lowest. Woodland hedgerow had diversity, field roads was relatively concentrated mainly influenced by human interference environmental filtering. These findings offer scientific support for preservation ecosystem services
