Resilience of Pinus durangensis Martínez in Extreme Drought Periods: Vertical and Horizontal Response of Tree Rings

Atmosphere, 2022
Extreme drought events reduce the productivity of forest ecosystems. One approach for estimating the effects of drought on forests is by assessing their resilience.

Growth and physiological responses of four kiwifruit genotypes to salt stress and resistance evaluation

Journal of Integrative Agriculture, 2019
In this study, four genotypes (Acva-1, Acva-2, Acva-3 and ZM-2) of Actinidia germplasm resources were grown in different NaCI concentrations (0, 0.4, 0.8 and 1.2 g L–1).

Juniper from Ethiopia contains a large-scale precipitation signal [PDF]

, 2008
Most semiarid regions are facing an increasing scarcity of woody vegetation due mainly to anthropogenic deforestation aggravated by climate changes. However, there is insufficient information to reconstruct past changes in climate and to evaluate the ...

Above- and below-ground competition in high and low irradiance: tree seedling responses to a competing liana Byttneria grandifolia [PDF]

, 2008
: In tropical forests, trees compete not only with other trees, but also with lianas, which may limit tree growth and regeneration. Liana effects may depend on the availability of above- and below-ground resources and differ between tree species.

High-Resolution X-Ray Computed Tomography: A New Workflow for the Analysis of Xylogenesis and Intra-Seasonal Wood Biomass Production

Frontiers in Plant Science, 2021
Understanding tree growth and carbon sequestration are of crucial interest to forecast the feedback of forests to climate change. To have a global understanding of the wood formation, it is necessary to develop new methodologies for xylogenesis ...

A Framework for Determining Population-Level Vulnerability to Climate: Evidence for Growth Hysteresis in Chamaecyparis thyoides Along Its Contiguous Latitudinal Distribution

Frontiers in Forests and Global Change, 2020
The impact of ecological and climatological factors on individual organisms over time and space is inherently complex and creates substantial uncertainty about how climate change will influence the global biosphere. To understand some of this complexity,

A complementary view on the growth of directory trees [PDF]

, 2009
Trees are a special sub-class of networks with unique properties, such as the level distribution which has often been overlooked. We analyse a general tree growth model proposed by Klemm {\em et.
