Excerpts

The results showed a clear trend in the proportions of the two ecological categories along the taxonomic scale ( Figure 4 : class level; Supplementary Figure 3 : other taxonomic levels and Supplementary Table 3 ).

Analysis with DNA isolation method 1 (ZymoBiomics) revealed relatively few but highly significant differences between sham and CS exposure.

Interestingly, compared with Control, abundance of “Metabolism” showed an increasing trend along with increasing pollution concentrations no matter in abundant or rare bacterial taxa.

With the increase of pollutant concentrations, the co-occurrence networks tended to be simplified, among which nodes and links showed a decreasing trend gradually ( Figure 3 ).

Significant or extremely significant differences in bacterial abundance were observed with variations in SeY doses among different diets administered to the sheep, indicating that these microbial communities might have a specific function in rumen metabolism; however, further studies are required to determine their exact role.

A decreasing trend immediately afterward led to complete absence of germination from the end of flowering (210 DFO; BBCH > 68) onward in year 3, while a few oospores also germinated at flowering and fruit development (211–240 DFO; BBCH > 60) in years 1, 2, and 4 ( Table 1 ).

The first principal component strongly correlated with five variables (G,T,SOT,DFO, and CR) and showed an increasing trend with T, SOT, DFO, and CR.

The European Center for Disease Prevention and Control (ECDC) reports that in the EU/EEA, 30 countries reported 2,502 listeriosis cases in 2017 and cases show an increasing trend ( ECDC, 2020 ), possibly due to the increasing size of the elderly population ( European Food Safety Authority, 2018 ).

fumigatus in the Netherlands also observed an increasing trend of triazole resistance in clinical A. fumigatus isolates ( Buil et al., 2019 ).

A certain crosstalk could also be observed, since IFN-γ treatment of A549 and Caco2 cells resulted in a moderate but highly significant increase of ISG15 expression.

In the surface layer, SOC, TN, C:N ratio POC%, and RP% showed an increasing trend with elevation; and M o :SOC ratio and LPI% showed an opposite trend ( Supplementary Table 2 ).

In the case of linalool and oh diol, a clear trend was not observed since in the first case, the best results were detected with the use of the immobilised enzyme (0.013 g/mL), and no significant differences were found between the rest of the enzymes.

For diet type1, we observed a decreasing trend for two pathways (Chlorocyclohexane and chlorobenzene degradation, and Fluorobenzoate degradation).

Comparative Genomics of HiVir/PASVIL Cluster and Role of Individual Genes in the Cluster Comparative genomic analysis showed a trend in the presence or absence of complete/conserved HiVir/PASVIL cluster genes in pathogenic vs. non-pathogenic P. ananatis strains.

Cyanobacterial biomass showed indeed a decreasing trend in Lake Zurich for 2009–2020 during which a series of four consecutive years (2014–2017) with incomplete winter mixing was recorded.

Moreover, we recorded a negative trend for annual population maxima and total population size, pointing to a potential nutrient limitation after a series of incomplete winter mixing.

As shown in Figure 5 , only hexanoylcarnitine levels were high for the first 4 days, whereafter a decreasing trend was observed.

Lipid Biomarkers and Diatom-Dinoflagellate Competition FA Biomarkers In our study, the two FA biomarkers, 16:1/16:0 and EPA/DHA, had highly significant responses to the changes in nutrient concentrations, showing higher values at higher nutrient concentrations ( Table 3 and Figures 6A,B ).

The nitrate concentration at sites 3 and 5 showed an increasing trend with increasing sediment depth, and showed no clear trend at sites 1 or 6.

Besides, phylum Firmicutes increased significantly on the 30th and 90th day, and had an increasing trend on the 60th day.

A p -value of <0.10 shows a trend, a p -value of <0.05 is significant, and p < 0.01 is extremely significant.

Another cluster encompassed variables that presented an increasing trend in the V3–V5 subjects, particularly in V4: the taxa Dorea , Ruminiclostridium , Lachnospiraceae UCG-004, Akkermansia , Allisonella , and unclassified Ruminococcaceae and Lachnospiraceae were associated with the dimethyl disulfide, phenol, benzenepropanoic acid, and 3-methylbutanoic acid.

At similar N application levels, the differences in bacterial and fungal community structures from bulk to rhizosphere soil showed an increasing trend.

Increasing nitrogen fertilization led to a decreasing trend in the variation of microbial community structures and demonstrated a more definite influence on fungal rather than bacterial community compositions and functions.

Abstract The Arctic environment is particularly affected by global warming, and a clear trend of the ice retreat is observed worldwide.
