ItemA survey of modern pollen and vegetation along an altitudinal transect in southern Georgia, Caucasus regionConnor, SE ; Thomas, I ; Kvavadze, EV ; Arabuli, GJ ; Avakov, GS ; Sagona, A (ELSEVIER SCIENCE BV, 2004)This paper describes the pollen representation of vegetation patterns along an altitudinal transect in the South Caucasus region. Surface sediments from eight small- to medium-sized lakes and wetlands were analysed for modern pollen, and the results analysed numerically using detrended correspondence analysis (DCA) and dichotomised ordination (TWINSPAN). Pollen spectra from the semidesert region have a clear palynological signal characterised by an abundance of Chenopodiaceae. Differentiation of oak forest, upper tree-line and subalpine communities is more difficult: all are dominated by arboreal pollen (AP) types. The authors propose a number of indicator pollen types and pollen threshold values that may assist in detecting tree-line variations and deforestation events in Holocene pollen diagrams.
