Holocene Evolution of Rubiaceae Plants, Middle Albania.

Abstract

For the realization of this scientific work, which is part of innovative studies, we have mainly focused on the presentation of data on fossil pollen, which belong to the New Holocene period. The study was carried out for the palynomorphs of the Rubiaceae family. The results obtained on the fossil pollen of Rubiaceae plants were obtained by analyzing the soil deposits that after the time assignment belong to almost the last 20 centuriesin the Elbasan area. The analyzed soil championships are fixed with a weight of 2500 grams and belong to the depth from 4 meters to the surface. Soil samples were taken at five stations in the Elbasan area during the SeptemberDecember 2022 period, by means of a dry rotary drilling probe with a diameter of 110 - 130 mm. This study was carried out with the aim of presenting the evolutionary line that the Rubiaceae plants followed during the late Quaternary period (corresponding to the New Holocene). Data on the fossil pollen of Rubiaceae plants are provided for the first time and there are no studies on the Rubiaceae Family for the region by other researchers. In conclusion, we found 555 palynomorphs of the Rubiaceae Family found in all soil samples analyzed from a depth of 4 meters towards the surface of the earth and we also find a consistent presence of these Palynomorphs. We are of the opinion that the vegetation change presented over the years is mainly related to the influence of the human hand on the cultivars, since there is no historical data on other factors that may have changed the vegetation.
