Article
Full-text available
Pollen-bearing lacustrine sediments developed as plastic clays, and silty to sandy clays with sand intercalations, over 5.75 m thick (bottom not exposed) occur in the lower part of the Middle Pleistocene section at Huba, the Orawa-Nowy Targ Intramontane Basin, West Carpathians (southern Poland). Their pollen diagram indicates middle to late climati...
Article
Full-text available
A recently developed semi-quantitative methodology for assessing Neogene zonal vegetation evolu-tion is applied to 19 Miocene/Pliocene plant localities/levels with at least two different organ assemblages. The results obtained from the different organ assemblages at each site are compared in order to test the validity of the applied method. The zon...
Article
Fossil sporomorphs dispersed in Neogene sediments are classified i two systems; natural system after the botanical affinity, and morphological system after the principles of morphology. The International Code of Botanical Nomenclature (ICBN) explicitly states the necessity of employment priority of taxonomic names for recent and fossil plants. This...
Article
Results of a revision of the macrofossil plant remains in collections of the Palaeobotanical Museum, of the W. Szafer Institute of Botany, Polish Academy of Sciences, from four localities referred to the Eemian interglacial in central and western Poland are presented. The state of each collection before and after the revision is presented on six ta...
Article
Results of a revision of the macrofossil plant remains collection from six Polish localities referred to the Mazovian interglacial are presented. This work is a continuation of the revision undertaken on the Polish Quaternary and Pliocene collections housed in the Palaeobotanical Museum of the W. Szafer Institute of Botany, Polish Academy of Scienc...
Article
On the basis of palynostratigraphic studies of some Badenian and Sarmatian profiles climatic parameters for the Central and Eastern Paratethys region (southern Poland and western Ukraine) have been established and the ecological structure of the vegetation analyzed. Using Grichuks method based on "climatic areals" for several profiles circograms an...
Article
The palynological diversity of surface samples from beech forests (Fagus orientalis in the Caucasus and Fagus sylvatica in the Carpathians) is characterized and its relationships to the species composition of modern vegetation is discussed. Some problems of beech ecology, relevant for the reconstructions of palaeovegetation are considered. The prob...
Article
At the northern margin of the Kolbuszowa Upland (southern Poland), a borehole was drilled north of Łowisko. In this borehole, the organic deposits covered with till of the South Polish (Sanian) Glaciation and resting on the fluvial deposits have been identified. setting of these deposits resembles that of Jasionka near Rzeszów. The pollen flora in...
Article
Pyrolytic methods (standard Curie-point pyrolysis and pyrolysis in the presence of tetramethylammonium hydroxide (TMAH), followed by gas chromatography–mass spectrometry, were used to analyze the organic composition of Glyptostrobus (Taxodiaceae) remains from the Miocene deposits of Lipnica Mala (Poland), consisting of branches with their leaves. T...
Article
More than 40 years of palynological studies in the Polish Neogene resulted in a basis for a palaeofloristic and palaeoclimatic synthesis. We have started with building up a palynological data base for correlation of palynofloras at the W. Szafer Institute of Botany, Polish Academy of Sciences in Krakow. For our use a computer programme was elaborat...
Article
Fossilized remains of Glyptostrobus europaeus from the Neogene sediments at Lipnica Mala have been chemically analyzed, using the analytical pyrolysis method. The obtained results have shown a normal distribution of the C13 to C27 alkenes. The alkylphenols were the major lignin fraction. The proportion of polycyclic aromatic molecules, more charact...
Article
Floristically, the region under investigation is unique. Numerous Tertiary relicts and endemics are concentrated here which are not only of Colchis, but also Talysh origin. Comparison of the pollen spectra with the vegetation composition on 20 test sites from different altitudinal zones, showed a number of important factors of subfossil spore-polle...
Article
One of the most characteristic features of Neogene palynocomplexes of Western Georgia (Colchis) is the abundance of spores, among which the genus Pteris is particularly prominent. Sixteen forms of this taxon are described. Starting with the first appearance of Pteris in geological history we present data about its distribution in the deposits of As...
Article
The variability of pollen spectra formed in the mountains depend not only from the floristical composition of the vegetation but also from other factors as relief, ecological and climatic conditions etc. Some differences in forming pollen spectra in Caucasus and Carpathians are also confirmed. A special attention was taken to pollen productivity an...
Article
Some palynological profiles of Late Pliocene and Early Pleistocene sediments from central Poland are described and from them five stages of vegetational development have been distinguished. Stage I, represented in the Różce profile, is characterized by mesophilous forests with predominance of warm-temperate deciduous trees, considerable admixtures...
Article
All dominants of trees (except Zelkova) in the forest are well represented in the pollen spectra. Pollen of Zelkova was found only sporadically. It seems to be caused by a low pollen productivity of Zelkova and poor bed preservation. -from Authors
Article
The paper presents a new formal lithostratigraphic unit the Biegonice Formation. This formation is dominated by laminated mudstones with intercalations of poorly cemented fine-grained sandstones in the lower part, and clayey shales and mudstones with numerous intercalations of lignites in the upper part. The Podegrodzie Conglomerate Member is local...
Article
The existence of a refuge of nemoral thermophilic flora on the territory of the Ugolsky beech forest massif in the Ukrainian Carpathians is suggested. This territory has probably played the role of a refuge since as early as the Miocene. -from Authors
Article
Tertiary sediments such as the whole brown coal series with three coal seams, and the main brown coal seam, as well as mineral sediments alternating with the coal layers of the Belchatow brown coal sedimentary basin are studied palynologically and for a selection of them carpological and leaf analyses have also been carried out. The swamp forest fa...
Article
The extent of preservation of the pollen in various sediments from different hypsometric levels is determined. Such investigations will make it possible to correctly decode not only the Holocene spore-pollen specta, but more ancient ones as well. -from Authors
Article
Among 144 species of Polemoniaceae which have been investigated 26 different pollen types have been found. Relationships between genera, sections and tribes are shown in Fig. 1. With regard to pollen morphology there are no direct connections between the tropical genera. Neither have the tribes Cobaeeae and Cantueae any connections with the other t...
Article
Twenty-six pollen types have been described from among 144 species investigated. The descriptions are supplemented by a table (with NPC-classification and short descriptions; see p. 200). For the determination of the pollen grains a key (p. 208) has been made. The relationships between genera, sections, and tribes are adumbrated in Fig. 1 (p. 198).
