We selected Larix principis-rupprechtii Mayr. in the Liupan Mountains area as a research object, dividing different competition levels of L. principis-rupprechtii Mayr. by using the intersection angle competitive index, established tree-ring width chronology of L. principis-rupprechtii Mayr. by...

Wildfires are one of the most important environmental factors controlling forest ecosystem physiology and the carbon balance in the permafrost zone of North Siberia. We investigated tree-ring width (TRW) and stable isotope chronologies in tree-ring cellulose (δ¹³C_Cell, δ¹⁸O_Cell) of Larix Gmelinii...

Fire disturbance has an important impact on the stability of forest ecosystem. Taking the Mohe forest area after the forest fire in May 1987 as the research object, the sample plots were set up according to different fire intensity. The tree ring sample cores of Larix gmelinii were collected in...

Objective: This paper aims to figure out the response differences of the radial growth of Larix gmelinii under different precipitation gradients in northern Daxing'an Mountains of northeastern China to climate, especially to recent warming. Method: In this paper, three sampling sites, including...

Tree-ring analysis provides an effective way to detect complex responses of trees to climate warming and has been extensively used in ecological studies; however, there is often a lack of simultaneous physiological investigations explaining the observed patterns. Here, we paralleled dendroclimatic...

Accurate measurements of ring-width series are essential for dendrochronological analyses. We present an R package MtreeRing for ring-width measurements on scanned digital images. A morphological alternate sequential filter is used for noise reduction in the original image. Ring boundaries are...

Although CO₂ fertilization on plant growth has been repeatedly modeled to be the main reason for the current changes in the terrestrial carbon sink at the global scale, there have been controversial findings on the CO₂ fertilization effects on forests from tree-ring analyses. In this study, we...

Kamchatka's forests span across the peninsula's diverse topography and provide a wide range of physiographic and elevational settings that can be used to investigate how forests are responding to climate change and to anticipate future response. Birch (Betula ermanii Cham.) and larch (Larix...

Global warming will significantly increase transpirational water demand, which could dramatically affect plant physiology and carbon and water budgets. Tree ring δ¹⁸O is a potential index of the leaf-to-air vapor-pressure deficit (VPD) and therefore has great potential for long-term climatic...

Winter snow plays a crucial role in regulating tree growth during the subsequent growing season in regions suffering seasonal or even annual drought stress, but the mechanisms of the potential compensation effect of winter snow on subsequent growing-season tree growth are not well understood. In...
