Plant–rodent interactions after a heavy snowfall decrease plant regeneration and soil carbon emission in an old-growth forest

Forest Ecosystems, 2021
Background Climate extremes are likely to become more common in the future and are expected to change ecosystem processes and functions. As important consumers of seeds in forests, rodents are likely to affect forest regeneration following an extreme ...

Microbial respiration and functional diversity of soil microbial community under treeline shifts in the Northwestern Caucasus

RUDN Journal of Agronomy and Animal Industries, 2021
In mountain areas, one of the noticeable results of modern climate change is rapid shift of treelines to subalpine and alpine meadows. Such vegetation shifts is associated with a change in quality of the plant residues entering the soils, which in turn ...

Analysis of oxygen consumption rates in zebrafish reveals differences based on sex, age and physical activity recovery

Frontiers in Physiology, 2023
Introduction: Mitochondrial dysfunction is linked to a variety of human diseases. Understanding the dynamic alterations in mitochondrial respiration at various stages of development is important to our understanding of disease progression.

Soil respiration across a permafrost transition zone: spatial structure and environmental correlates [PDF]

Biogeosciences, 2017
Soil respiration is a key ecosystem function whereby shifts in respiration rates can shift systems from carbon sinks to sources. Soil respiration in permafrost-associated systems is particularly important given climate change driven permafrost thaw ...

Hypoxia and hyperglycaemia determine why some endometrial tumours fail to respond to metformin [PDF]

, 2020
High expression of Ki67, a proliferation marker, is associated with reduced endometrial cancer-specific survival. Pre-surgical metformin reduces tumour Ki-67 expression in some women with endometrial cancer. Metformin's anti-cancer activity may relate to

Physical, chemical, and biological properties of soil under soybean cultivation and at an adjacent rainforest in Amazonia [PDF]

Revista Ambiente & Água, 2015
Land-use change in the Amazon basin has occurred at an accelerated pace during the last decade, and it is important that the effects induced by these changes on soil properties are better understood.

Relations between soil respiration, humus quali­ty and ca­tion exchange capacity in selected subtypes of chernozem in South Moravia region

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008
Soil organic matter (SOM) undergoes short and long-term transformation in the soil. Microorganisms through their enzymes are able to mineralize organic carbon while the rate of this process is different. Biological test though referred to one of the main
