Exploring tree-ring anatomy to improve hydroclimate reconstructions in Northern Europe

The extreme European summer heat-droughts of 2003 and 2018, compounded by the threat of continued climate change, highlight the need to better understand the frequency, severity and seasonality of such events. The widths of annual tree rings currently provide the most detailed and spatially complete proxy information of European hydroclimate of the ...

Variations of Wood Anatomy and δ13C Within-Tree Rings of Coastal Pinus Pinaster Showing Intra-Annual Density Fluctuations

IAWA Journal, 2007
We investigated the variation of wood anatomical characteristics and carbon isotopic composition of tree rings showing intra-annual density fluctuations (IADFs) in plants of Pinus pinaster Ait. growing at a coastal plantation in Tuscany (Italy).

The response of δ13C, δ18O and cell anatomy of Larix gmelinii tree rings to differing soil active layer depths

Dendrochronologia, 2015
Abstract Global warming is most pronounced in high-latitude regions by altering habitat conditions and affecting permafrost degradation, which may significantly influence tree productivity and vegetation changes. In this study, by applying a “space-for-time” approach, we selected three plots of Larix gmelinii forest from a continuous permafrost zone ...

Tree-ring wood anatomy and stable isotopes show structural and functional adjustments in olive trees under different water availability

Plant and Soil, 2013
Olive tree (Olea europaea L.) is a drought-tolerant tree species cultivated in Mediterranean-type environments. Although it is tolerant to drought, dry conditions decrease its productivity. A thorough analysis of the hydraulic architecture and wood anatomical plasticity, as well as of their physiological significance, is needed to understand how olive ...

What tree rings can tell us about the competition between trees and lianas? A case study based on growth, anatomy, density, and carbon accumulation

Dendrochronologia, 2017
In tropical forest, landscape fragmentation and the consequent degradation of disturbed forests increase the incidence of light and dry hot winds, causing a disturbance on natural regeneration. Under these conditions, lianas (woody vines) development is stimulated instead of other species, which are more suited to mature forest and under less influence

Fennoscandian AND Yamalian tree-ring anatomy shows a warmer modern than medieval climate

Earth system models and various climate proxy sources indicate that global warming is unprecedented during at least the Common Era. However, tree-ring proxies often estimate temperatures during the Medieval Climate Anomaly (950–1250 CE) to be similar, or exceed, those recorded for the past century.

Integrating inter- and intra-annual tree-ring width, carbon isotopes and anatomy : responses to climate variability in a temperate oak forest.

2015
While many forests are experiencing strong tree declines due to climate change in temperate ecosystems, others nearby to those declining show no apparent signs of decline. This could be due to particular microsite conditions or, for instance, to a higher plasticity of given traits that allow a better performance under stressful conditions.
