Dendrochronology Principles Flashcards
dendrochronology
“tree-time-knowledge”
In practice, it is the use of tree-rings to determine the timing of events in the past
how did Theophrastus contribute to dendrochronology?
He recognized and wrote that tree rings were annual features that he could see in trees
how did Leonardo DaVinci contribute to dendrochronology?
He recognized that the tree-rings in trees were wider in wet years as oppose to dry years.
how did A.E. Douglass contribute to dendrochronology?
He noticed that the pattern of narrow and wide tree-ring widths had the same pattern as the stump of the trees that were cut down years prior
dendro-archaeology
the use of tree rings to date prehistoric artifacts
art-dendroarcheology
the use of tree rings to date frames of paintings, and musical instruments for authenticity
dendro-geomorphology
tree rings used to date slope movement and volcanic eruptions
dendro-ecology
the use of tree rings to date ecological events such as forest fires and tree age
what is the vascular cambium also called
lateral meristem
what is the lateral maristem
it is a sheath of cells that covers all the woody parts of the whole tree.
where is the lateral meristem located
right under the bark
what does the lateral maristem divide
xylem cells on the inside and phloem cells outside
what is the function of the xylem
the xylem transports water from the soil upwards and out to the leaves
what is the function of the phloem
the phloem transports photosynthate from the leaves inward and down to all living parts of the tree
what is photosynthate
a sugar created by photosynthesis
