TLDR
If severe droughts become more frequent, due to a greater climatic variability, extensive dieback of marginal Q. faginea populations may be expected.Abstract:
We studied the growth response to drought of a Quercus faginea Lam. stand in a xeric site in NE Spain, that experienced an intense defoliation in 1993–94. This event coincided with very low precipitation from November to February, the period when total monthly precipitation exceeds evapotranspiration. We evaluated the effects of November–February precipitation (recharge precipitation, RP) on internode length, radial growth, and wood anatomy. Quercus faginea showed reduced longitudinal and radial growth during the years with low RP, and most sampled trees did not produce latewood in 1993–94 but showed wide earlywood vessels. We observed the reverse for years with a high RP. Radial growth was enhanced by increased precipitation during January and May of the growth year. If severe droughts become more frequent, due to a greater climatic variability, extensive dieback of marginal Q. faginea populations may be expected.read more

Studying global change through investigation of the plastic responses of xylem anatomy in tree rings
Patrick Fonti,Georg von Arx,Ignacio García-González,Britta Eilmann,Ute Sass-Klaassen,Holger Gärtner,Dieter Eckstein +6 more
TL;DR: It is believed that the study of tree-ring anatomy is emerging as a promising approach in tree biology and climate change research, particularly if complemented by physiological and ecological studies.

Intra-annual radial growth and water relations of trees: implications towards a growth mechanism
TL;DR: A concept is discussed which links radial growth over a feedback loop to actual tree water-relations and long-term affected C-storage to microclimate and suggests a strong dependence of radial growth on the current tree water relations and only secondarily on the C-balance.

Impacts of drought at different time scales on forest growth across a wide climatic gradient in north-eastern Spain
TL;DR: The findings should be useful to understand forest responses to climate change, and to adapt appropriate management strategies to mitigate the impact of drought on tree growth.

Scanning the genome for gene single nucleotide polymorphisms involved in adaptive population differentiation in white spruce.
TL;DR: The results suggest that an approach separating the locus and population effects is useful to identify genes potentially under selection and these candidates are worth exploring in more details at the physiological and ecological levels.

Effects of stand composition and tree size on resistance and resilience to drought in sessile oak and Scots pine
TL;DR: In this work, the importance of taking into account stand composition and trees size as well as soil and climatic conditions for each drought events to achieve a better understanding of the diversity of responses to climatic variations among forest ecosystems is stressed.
