Three Bermudagrass-suppression techniques have little effect on soil-nutrient availability and microbial communities 200 days after application

Sub-Lethal Effects of Pesticides on the DNA of Soil Organisms as Early Ecotoxicological Biomarkers

“…The only significant difference was observed between communities of different locations, but this difference was found to be related only to the field differences rather than treatment impact. Although overall changes and compositions generally suggested the absence of overlap following treatments with herbicides, Farthing et al (2020) found that changes in a number of OTUs were quite similar regardless of the experimental site. This phenomenon was still observed a year following the treatment.…”

“…Differences were found both at the phylum and genus levels in both inoculated and non-inoculated soils due to accumulation of IPP metabolites. Farthing et al (2020) found that commonly used weed suppression techniques of repeated glyphosate application, repeated glyphosate application + imidazolinone herbicide use, and repeated glyphosate application + mechanical above-ground biomass removal had only little impact on bacteria and archaea. In particular, none of the these weed-suppressing techniques had a significant impact over controls in terms of α-diversity indexes (species richness and Shannon diversity).…”

Equilibrium in soil respiration across a climosequence indicates its resilience to climate change in a glaciated valley, western Himalaya

“…The data's normal distribution and homogeneity of variance were determined through Shapiro–Wilk and Levene's test, respectively. Since the data did not meet the assumption of normality and homogeneity even after log transformation, we conducted Welch's analysis of variance (ANOVA) to assess differences in parameters among different elevations 40 . Where differences existed, we used the post-hoc Games-Howell test for pairwise comparisons.…”

Soil bacterial community diversity and composition vary more with elevation than seasons in alpine habitats of western Himalaya

“…Normal distribution and homogeneity of variance of these indices and environmental variables were assessed using Shapiro-Wilk test and Levene’s test, respectively. Since most of the data did not show normal distribution and equal variances, we used Welch’s ANOVA [50] and Mann-Whitney U test to assess variation among habitats and seasons respectively. Further, effect sizes (Cohen’s d with hedges correction) were collected to quantify differences in environmental variables and alpha diversity indices [51, 52].…”
