Prediction of plant species occurrence as affected by nitrogen deposition and climate change on a European scale
Biodiversity Climate change Nitrogen deposition Precipitation Soil EUNIS
2023/12/19
Plant species occurrence in Europe is affected by changes in nitrogen deposition and climate. Insight into potential future effects of those changes can be derived by a model approach based on field-b...
Differential Response of Soil Respiration and Total Belowground Carbon Allocation to Simulated Nitrogen and Phosphorus Deposition in Moso Bamboo Forests
N and P deposition autotrophic respiration heterotrophic respiration net ecosystem production root carbon-use efficiency
2023/11/22
Elevated nitrogen (N) and phosphorus (P) depositions have greatly affected belowground carbon processes in forest ecosystems. However, open questions still remained on the effects of N and P depositio...
Effects of One-Year Simulated Nitrogen and Acid Deposition on Soil Respiration in a Subtropical Plantation in China
nitrogen deposition acid deposition soil respiration subtropical forest
2024/2/5
Atmospheric nitrogen (N) and acid deposition have become global environmental issues and are likely to alter soil respiration (Rs); the largest CO2 source is from soil to the atmosphere. However, to d...
Tissue Fatty Acid Deposition, Plasma Lipid and Cytokine Profile in Pigs Fed a Diet with Fish Oil or Palm Oil
EPA DHA cholesterol IL-10 TNF-α cardiovascular diseases feed ration pig muscle
2018/3/5
The present study tested a hypothesis concerning a favourable effect of dietary fish oil on the tissue polyunsaturated
fatty acid (PUFA) deposition, and on plasma lipid and cytokine profile. Thirty-t...
Identification and characterization of novel single nucleotide polymorphism markers for fat deposition in muscle tissue of pigs using amplified fragment length polymorphism
Amplified Fragment Length Polymorphism (AFLP) Intramuscular Fat, Fatty Acid Pig
2017/3/9
This study was conducted to identify and evaluate the effective single nucleotide polymorphism (SNP) markers for fat deposition in the longissimus dorsi muscles of pigs using the amplified fragment le...
Lower ω-6/ω-3 Polyunsaturated Fatty Acid Ratios Decrease Fat Deposition by Inhibiting Fat Synthesis in Gosling
ω-6/ω-3 Polyunsaturated Fatty Acid Lipid Metabolism Goose
2016/11/10
The objective of the current study was to investigate the effects of dietary ω-6/ω-3 polyunsaturated fatty acid (PUFA) ratios on lipid metabolism in goslings. One hundred and sixty 21-day-old Yangzhou...
Long-term administration of DHEA prevents fat deposition in rats fed a high-fat diet
dehydroepiandrosterone lipid metabolism lipogenic gene expression
2016/5/11
The effects of dehydroepiandrosterone (DHEA) on lipid metabolism and lipogenic gene mRNA expression in rats subjected to a high-fat diet were determined. Totally 75 rats were randomly divided into 5 g...

2015/4/24
We documented the current typological and phytosociological characterisation of the ground vegetation as an essential component of biodiversity in 154 Czech forest monitoring plots and to describe its...
Comparison of deposition fluxes on the open area and in mountain spruce stands of different density
throughfall Norway spruce Moravian-Silesian Beskids Mts
2015/3/16
To better understand the chemical transformation of rainfall after the passage through the canopies it is necessary to study throughfall deposition fluxes within forest stands. The comparison of bulk ...
Modelling the impact of acid deposition on forest soils in North Bohemian Mountains with two dynamic models: the Very Simple Dynamic Model (VSD) and the Model of Acidification of Groundwater in Catchments (MAGIC)
