Impact of land use on soils microbial activity

Journal of Water and Land Development, 2017
The article considered the influence the various types of land use on microbial activity of soils and thus using this parameter as a universal test of soil quality. Samples for soil respiration studies were taken from agricultural areas, meadows, forests

Geological CO2 affects microbial respiration rates in Stavešinci mofette soils

Acta Biologica Slovenica, 2009
Substrate-induced respiration (SIR) was used to estimate microbial respiration and microbial biomass in soils from Stavešinci natural CO2 spring (mofette) exposed to different geological CO2 concentrations.

Hormone deprivation alters mitochondrial function and lipid profile in the hippocampus [PDF]

, 2017
Mitochondrial dysfunction is a common hallmark in aging. In the female, reproductive senescence is characterized by loss of ovarian hormones, many of whose neuroprotective effects converge upon mitochondria.

Soil respiration in a northeastern US temperate forest: a 22‐year synthesis [PDF]

, 2013
To better understand how forest management, phenology, vegetation type, and actual and simulated climatic change affect seasonal and inter‐annual variations in soil respiration (Rs), we analyzed more than 100,000 individual measurements of soil ...

Soil biological activity under different land-uses in Leyte Philippines

Annals of Tropical Research, 2006
On seven sites in Western Leyte, Philippines, different land uses, namely reforestation with indigenous tree species (‘rainforestation’), reforestation with exotic tree specie Gmelina arborea, and traditional fallow/grassland use were compared with ...

Ketone body β-hydroxybutyrate (BHB) preserves mitochondrial bioenergetics

Scientific Reports, 2023
The ketogenic diet is an emerging therapeutic approach for refractory epilepsy, as well as certain rare and neurodegenerative disorders. The main ketone body, β-hydroxybutyrate (BHB), is the primary energy substrate endogenously produced in a ketogenic ...

Comparative Assessment of the Effect of Synthetic and Natural Fungicides on Soil Respiration

Sensors, 2012
As toxic pesticide residues may persist in agricultural soils and cause environmental pollution, research on natural fungicides to replace the synthetic compounds is currently increasing. The effect of the synthetic fungicide chlorothalonil and a natural

Microbial carbon mineralization in tropical lowland and montane forest soils of Peru [PDF]

, 2016
Climate change is affecting the amount and complexity of plant inputs to tropical forest soils. This is likely to influence the carbon (C) balance of these ecosystems by altering decomposition processes e.g., "positive priming effects" that accelerate ...
