Eco‐Geography Reverses Dominant AMR Reservoirs in Klebsiella pneumoniae: Integron‐Rich Mobilomes and Cross‐Niche Connectivity

Advanced Science, EarlyView.
Dominant antimicrobial resistance reservoirs in Klebsiella pneumoniae vary across eco‐geographic settings rather than following a universal pattern. Integrated One Health and global genomic analyses show that lineage structure, integron load, and cross‐niche connectivity shape whether AMR burden accumulates primarily in human or nonhuman compartments ...

Microbiological characteristics оf cambisols from Western Balkan Mountains (Bulgaria)

Почвознание, агрохимия и екология, 2016
Changes in microbial population density and basal soil respiration of Cambisols from Western Balkan Mountains due to the influence of vegetation cover (grassland, pine forest and beech forest) were studied, and their relations with soil properties were ...

Respiration from C-3 plant green manure added to a C-4 plant carbon dominated soil

, 2000
Application of tree leaves (C3 plants) on maize (Zea mays L.) (C4 plant) fields is an agroforestry management technology to restore or maintain soil fertility. The rate at which the tree leaves decompose is crucial for the nutrient supply to the crop. We

A Disaggregation Strategy for Nanopesticide Fabrication: Investigating the Impact of Nanosizing on Pesticide Biointeractions

Advanced Science, EarlyView.
To explore the impact of nanosizing on pesticide biointeractions, a 7‐nm (average) emamectin benzoate nanopesticide without nanocarriers or surfactants is fabricated via HOAc‐mediated disaggregation. Nanosizing enhances bioactivity against Megalurothrips usitatus and Meloidogyne enterolobii and improves plant penetration.

Evaluation of soil respiration characteristics to assess heavy-metal effects on soil-microorganisms using glutamic-acid as a substrate

, 1988
Computerized continuous monitoring of soil respiration rates before and during glutamic acid decomposition in heavy metal polluted soils was used to determine four microbial parameters: basal respiration rate, substrate induced respiration rate, lag time

Changes in the soil's biological and chemical properties due to the land use

Soil and Water Research, 2020
Increasing the soil productivity is challenged by the increasing biotic threat to plants and microorganisms, by the resistance to agrochemicals, and by the declining soil health. Soil management strategy is, therefore, aimed at erosion prevention and the

Characteristics of microbial biomass carbon and respiration activities in arable soil and pasture grassland soil [PDF]

Journal of Central European Agriculture, 2012
The aim of our work was to survey and state the representative values and range of the microbial biomass carbon (Cmic) and microbial respiration activities in arable soils of three types (Chernozem, Luvisol, Planosol) and in pasture grassland soil ...

Methodological peculiarities of basal respiration measurement of organogenic samples of peat soils

Lomonosov Soil Science Journal
Methodological peculiarities of basal respiration (BR) measurement have been studied on the peat soil samples from two taiga subzones. It is found that the BR values at the initial incubation time (30 minutes) significantly exceed the ‘classical’ variant (24 hours) and gradually decrease with time. It is observed for all types of samples.

Immediate and carry-over effects of increased soil frost on soil respiration and microbial activity in a spruce forest

, 2019
Increased soil frost associated with winter climate change could have immediate and carry-over effects on biological processes in high-altitude forest soils, but the nature of these processes remain poorly understood.
