Trends in tree-ring width of treeline trees along latitudinal gradient from subtropics to the Arctic.
 Zborníková, Kateřina ; Treml, Václav (advisor) ; Mašek, Jiří (referee)
This bachelor thesis is interested in a tree ring of trees at the treeline from subtropics to the arctic and the main aim of this work is to find if there is a trend in the tree ring width at the treeline along the latidunial gradient. The work/thesis focuses on conifers. The data were obtained from International Tree-Ring Data Bank database, article searches and from the internal workplace database. A total of 9859 annual ring samples were obtained from 153 localities in Europe. Trees of the genus Pine (Pinus), Spruce (Picea) and Fir (Abies) were selected, which dominate the europeans ecotones of treeline. After removing the age trend, the regression of tree ring width and the latitude, were calculated. The results showed that in most cases the tree ring width decreases with higher latitude. However, a small number of tree ring samples from latitudes around 55ř north latitude adds to the uncertainty of this claim.
