TL;DR: In this article, a reconstruction of the European Alps for the a.d. 755-2004 period is presented, based on 180 recent and historic larch [Larix decidua mill] density series.

TL;DR: In this paper, an analysis of maximum latewood density data from northern Scandinavia, along with published dendrochronological records, finds evidence that previous tree-ring-reliant reconstructions of large-scale near-surface air temperature underestimated long-term pre-industrial warmth during Medieval and Roman times.

TL;DR: A microtome designed for the surface preparation of entire increment cores allows cutting plane surfaces on cores up to a length of 40 cm as discussed by the authors, which can be used for a more detailed analysis of variations in the tracheid structure of conifers and vessel sizes of oak.

TL;DR: The long-term history of Zeiraphera diniana Gn.

TL;DR: In this article, the authors quantify the response of radial conifer stem size to environmental fluctuations via a novel assessment of tree circadian cycles, and show that changes in precipitation, temperature and cloud cover have a substantial effect on typical growing season diurnal cycles; amplitudes were nine times smaller on rainy days (>10mm), and daily amplitudes are approximately 40% larger when the mean daily temperature is 15-20°C than when it is 5-10°C.
