Spruce up your climate analysis: Dendroclimatology of Picea engelmannii and Picea pungens

Ecosphere, Volume 15, Issue 11, November 2024.
Abstract Warming and more variable climates threaten to upend historical tree ranges, climatic sensitivity, and vigor. In western North America, the species Picea engelmannii var. engelmannii Parry ex Engelmann (Engelmann spruce) and Picea pungens Engelmann (Colorado blue spruce) are widespread spruce that act as foundational species in their montane ...

Dendroecology of Macrolobium acaciifolium (Fabaceae) in Central Amazonian floodplain forests [PDF]

Acta Amazonica, 2018
The forest dynamics in the Amazonian floodplains is strongly triggered by the flood pulse. Trees respond to unfavorable growth conditions during the flood period by cambial dormancy, which results in the formation of annual growth rings.

Competitive interactions under current climate allow temperate tree species to grow and survive in boreal mixedwood forest

Ecography, Volume 2023, Issue 5, May 2023., 2023
With climate change, climatic optima are shifting poleward more rapidly than tree migration processes, resulting in a mismatch between species distributions and bioclimatic envelopes. Temperate hardwood tree species may take advantage of the release of climate constraints and forest management to migrate into the boreal forest.

Using machine learning on tree‐ring data to determine the geographical provenance of historical construction timbers

Ecosphere, Volume 14, Issue 3, March 2023., 2023
Abstract Dendroclimatology offers the unique opportunity to reconstruct past climate at annual resolution and wood from historical buildings can be used to extend such information back in time up to several millennia. However, the varying and often unclear origin of timbers affects the climate sensitivity of individual tree‐ring samples.

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 ...

Frequencies of Multivariate Air Masses Drive Tree Growth

Journal of Geophysical Research: Biogeosciences, Volume 128, Issue 3, March 2023., 2023
Abstract Midlatitude surface meteorological conditions are embedded within—and affected by—synoptic‐scale systems, including the movement and persistence of air masses (AMs). Changes in AM frequencies (number of daily occurrences) over the past several decades could have large effects on ecosystems: each organism is exposed to the synergistic effects ...

Dendrochronological Potential of Drought-Sensitive Tree Stands in Armenia for the Hydroclimate Reconstruction of the Lesser Caucasus

Atmosphere, 2021
Existing high-resolution reconstructions of hydroclimate variability in the Caucasus are lacking tree-ring data from Armenian Plateau, the most continental part of the region.

Spatio‐Temporal Variations in Carbon Isotope Discrimination Predicted by the JULES Land Surface Model

Journal of Geophysical Research: Biogeosciences, Volume 127, Issue 12, December 2022., 2022
Abstract Stable carbon isotopes in plants can help evaluate and improve the representation of carbon and water cycles in land‐surface models, increasing confidence in projections of vegetation response to climate change. Here, we evaluated the predictive skills of the Joint UK Land Environmental Simulator (JULES) to capture spatio‐temporal variations ...

Old World megadroughts and pluvials during the Common Era [PDF]

, 2015
Climate model projections suggest widespread drying in the Mediterranean Basin and wetting in Fennoscandia in the coming decades largely as a consequence of greenhouse gas forcing of climate.
