TLDR
In this article, the effects of probable climate change on CO2 exchange and temperature dependence of net photosynthesis in the larch and Siberian stone pine undergrowth formed in the light larch forests of West Siberia were studied in chambers with an artificial climate.Abstract:
The effects of probable climate change—an increase in atmospheric CO2(by two times), air temperature, precipitation—on CO2exchange and temperature dependence of net photosynthesis in the larch and Siberian stone pine undergrowth formed in the light larch forests of West Siberia were studied in chambers with an artificial climate. The change of the aforementioned ecological factors caused an increase in the temperature optima of photosynthesis and the range of optimum temperatures (in the case of Siberian stone pine, to a slightly greater degree). Therefore, the ranges of both species may broaden, and the Siberian stone pine can expand to the north, displacing larch tree stands.read more

Lower forest-grassland ecotones and 20th Century livestock herbivory effects in northern Mongolia
TL;DR: In this article, the effects of 20th century grazing regimes and changes in grazing management on ecotone dynamics at a local scale were investigated in the Darhad valley in northern Mongolia, where a total of 2968 Siberian larch trees were cored and tree-age distribution was constructed to determine 20th Century tree establishment.

Response of Pinus koraiensis seedling growth to different light conditions based on the assessment of photosynthesis in current and one-year-old needles
TL;DR: Findings suggest that P. koraiensis is the in-between heliophilous and shade-tolerant tree species at least for the seedlings up to 8 years.

Model of Plant Productivity and a Computer System for Optimization of Agro-Technology Using the Method of Exergic Analysis
TL;DR: In this paper, a model of a potentially effective type energy-resource-saving of optimization of agro-technologies, based on the principle subordination of synergetics, was established.
Response of Pinus koraiensis seedling growth to different light condi- tions based on the assessment of photosynthesis in current and one-year-old needles
TL;DR: In this article, a study was conducted to understand how Pinus koraiensis seedlings adapt to different light intensities and what would be the optimum light level for their establishment and growth.

More Efficient Plants : a consequence of rising atmospheric CO2
TL;DR: The primary effect of plants response of plants to rising atmospheric CO2 (Ca) is to increase resource use efficiency, and at the same time it stimulates higher rates of photosynthesis and increases light-use efficiency as discussed by the authors.
