Wood, bark and climate

Subject description

The course deals with wood and bark as tissues formed by the cambium under the influence of internal and external (environmental) factors. The topics: cambium as a meristem, its function, cell division, formation of secondary xylem and phloem. Seasonal dynamics of wood and phloem formation in conifers and dycotiledon trees in temperate, cold (boreal) and Mediterranean climate. Models of dynamics of wood formation. Influence of external factors on dynamics of wood and phloem formation and survival strategies of trees in terms of climate change. Methods for monitoring of process in the cambium in adult trees and techniques of tissue preparation. Specific use of microscopic techniques: light microscopy, transmission electron microscopy, UV-microspectrophotometry. Dendrochronology, tree-rings as an archive, tree-ring analysis and reconstruction of historical events. Wood as a tree tissue, raw material and wood in cultural heritage – from the perspective of wood structure and dendrochronology.

Dendrochronological, wood anatomical  climatic and phenological data bases and their use for studying the impact of climate and environment on wood and phloem tissue production. Wood, reconstruction of climate, dendroecology. Paleoclimatic data sources. Environmental sources of variability of phenological development on different time (decade, century and millennium) and spatial (local, regional, global) scales.
