Opis:
Palynological studies have been done to compare the Upper Ordovician strata in various geological units of northern and central Poland (epi-Caledonian Platform, East European Platform, Małopolska Block and Holy Cross Mountains–Łysogóry Fold Zone and Kielce Fold Zone). Two distinct palynological assemblages have been distinguished in the studied material: the Caradoc assemblage I and the Ashgill assemblage II (with two sub-assemblages IIa and IIb), thus demonstrating usefulness of the Upper Ordovician palynomorphs for biostrati- graphy. Thermal maturity of organic matter was studied using the TAI method. The palynological analysis, palynostratigraphy, and estimates of thermal maturity were done with the aim at palynological characterization of three ancient units: the Avalonia, Baltica and the Małopolska Block, all now participating in structures of the present-day geological units of northern and central Poland.

It was used the method of overlapping of "climatic areals" plants -- components of the fossil flora. Reconstruction of palaeotemperature ranges are made for each of the picked up regional pollen zones that has allowed to trace process of changing palaeotemperatures during chronologically consecutive phases in development of flora and vegetation of every interglacials. The reconstructions performed for four interglacials of the Pleistocene of Belarus have shown that temperatures of the warmest and coldest months were similar to each other and the highest ones recorded during the climatic optima of the Belovezhian and Muravian interglacials. The Mogilevian and Alexandrian interglacials were also similar in palaeotemperature parameters, but colder than the above-mentioned interglacial

The assemblages from Vietnam largely resemble those from Europe, Iran and Afghanistan; this analogy permitted dating the upper part of the Suoi Bang Formation at the Rhaetian-Lias.
W górnej części formacji Suoi Bang w północnym Wietnamie (fig. 1, 2) znaleziono zespół miospor i ziarn pyłku, z którego oznaczono 43 taksony (tabela 1—4, pl. 23—28), w tym dwie nowe kombinacje: Deltoidospora concava (Bolkhovitina) comb. nov. i Polypodiites polymicroforatus (Orłowska-Zwolińska) comb. nov. Istnieje duży stopień podobieństwa zespołów miospor i ziarn pyłku z Wietnamu z zespołami Europy, Iranu i Afganistanu (tabela 5), co pozwoliło określić wiek górnej części formacji Suoi Bang jako retyko-lias.

Opis:
Based on quantitative and qualitative analyses of the Triassic miospores assemblages from different regions of Poland climatic changes have been documented. Analyzed material came from the published and archival works of Orłowska-Zwolińska and author and comprised ten palynological zones distinguished in the Triassic of Poland. Two different palynological methods were applied in this study – PPC model and SEG model – to obtain palaeoclimatic and palaeoenvironmetal data. Xerophytic elements (spores and pollen grains of xerophytic plants), reflecting mainly dry climate conditions, dominated in the palynomorph spectra of the Triassic deposits from Poland. Significant numbers of hygrophytic elements indicating temporary more humid phases occurred in the late Olenekian, Ladinian, the middle Carnian, late Norian and the Rhaetian.

Opis:
Cultural layers from early medieval strongholds in Pszczew and Santok have been examined for the presence of pollen grains and spores as well as residues of fungi. The presence of the following remains has been recorded: fossil hyphopodia of Gaeumannomyces, teliospores of Puccinia, spores of Bipolaris, Thecaphora and Tilletia, teliospores of the genus Urocystis, Ustilago and Uromyces, ascocarps (perithecium) of the Ascomycota or the pycnidium of Sphaeropsidales. A greater diversity and abundance of fungi spores sensu lato was recorded in Santok, as compared to Pszczew. Both early medieval sites recorded a significant proportion of cereal pollen, including Secale cereale. It remains an undisputed fact that the grains and other plants collected in both strongholds were strongly infected with fungi. The analysis of the cultural layers for the presence of fungi remains provides significant data on the presence of certain species of plants and their growth conditions in natural environments and in agriculture.

Opis:
Palynological assemblages from the Camdag area of NW Turkey are analysed quantitatively and qualitatively. All preparations logged from different palynomorph sampling sections show high ratios of pollen. Within the pollen fraction percentages of up to 71% for the bisaccate pollen Lueckisporites Potonie and Klaus 1954 are remarkable. This pattern is reminiscent of palynofloras described from the Upper Permian of Europe. This enables the study area to be shown in its palaeogeographic context, and constrains interpretation of microfloral affinities, palynostratigraphy, and depositional environment. The palaeoenvironmental model clearly indicates deposition within the hinterland, corroborating previous interpretations.

Opis:
New palynological studies of the Carboniferous clastic deposits of SW Poland from six deep boreholes have provided diverse, but poorly preserved miospore assemblages. Probably all of these are mixed, consisting of taxa typical of the in terval from the Famennian to the Namurian. Namurian A deposits have been identified in the Paproć 29 and Katarzynin 2 boreholes. The stratigraphic position of rocks from other profiles, where miospores were more badly preserved, has been established in a more general way. In the Objezierze IG 1 borehole the rocks were dated as not older than late Viséan while rocks from the Kalisz IG 1, Dankowice IG 1 and Dymek IG 1 boreholes are considered as not older than Viséan. The abundance of reworked miospores in rocks from the Paproć 29 and Katarzynin 2 boreholes is proof that cannibalzation of older rocks containing miospores took place in this sedimentary basin in the early Namurian. Source rocks belonged either to the Famennian-Tournaisian and Viséan or to a Viséan inter valcontaining Famennian-Tournaisian reworked miospores. Some observations on the limitations of the stratigraphical interpretation of those mixed and poorly preserved miospore assemblages are provided.

Opis:
A 90 m-thick brown coal seam, the result of organic matter deposition in a fault-trough, is exploited in an open cast mine at Lubstów (Central Poland). Palynological analysis was conducted in order to determine which plants were the source of or ganic matter forming such a thick coal bed. The pollen spectrum is dominated by the gymnosperm pollen Inaperturopollenites, produced by trees closely related to the extant genera Taxodium and Glyptostrobus, the dominant constituents of swamp forests in SE North America and SE Asia today. However, the lack of xylites and preserved tissues in the coal does not support the conception of a swamp forest as the peat-producing community. There is also a significant percent age of angiosperm pollen in the coal, mainly from the groups: Castaneoideapollis, Tricolporopollenites exactus and T. pseudocingulum. The plants producing these pollen were probably the main constituent of the peat-producing community. The community shows signs of a shrub swamp with local tree islands and a low water table. Evidence for this also includes the de trital type of coal, the lack of preserved plant tissues and the presence of fungal remains. These character is tics show the existence of aerobic zones at the time of peat production. The peat was probably derived from angiosperms. Dome-shaped forms in the up per part of the de posit are the re mains of tree is lands. As de tri tus ac cu mu la tion is very rapid on the sur faces of pres ent-day tree is lands, a sim i lar rate of de po si tion may have taken place dur ing peat pro duc tion at Lubstów. This, com bined with sub si dence in the fault-trough, ex plains the great thick ness of the coal bed.

Opis:
Palynological analysis of core Butovka obtained from the Protva River basin 80 km south-west of Moscow (55 stopni10'N, 36 stopni 25'E) provides a record of vegetation and climate change in the central Russian Plain spanning the Last Interglacial and the beginning of the following glacial epoch. Pollen profiles of the Mikulino (Eemian) Interglaciation in the Central Russian Plain show a distinctive pattern of the vegetation changes, reflecting an increase in temperatures towards the optimum phase of the interglaciation followed by a gradual cooling. Rapid climatic deterioration, manifesting an onset of the Valdai (Weichselian) Glaciation, took place after a slower cooling accompanied by increasing humidity of climate during the post-optimum part of the Mikulino Interglaciation. The interglacial/glacial transition had a complex structure, being marked by a sequence of secondary climatic oscillations of varying magnitude. A decreasing role of mesophilic plants and an increase in abundance and diversity of the xerophytes and plants growing at present in the regions with highly continental climate in the Butovka pollen record suggests that during the Early Valdai the climate grew both more continental and arid. With this tendency at the background, two intervals of climatic amelioration can be distinguished. Both of them are marked by the development of the open forest communities similar to the contemporary northern taiga of West Siberia. The latter of the two warm intervals had a larger magnitude of temperature changes than the first one, as indicated by a greater landscape role of dark-coniferous trees (Picea + Abies + Pinus sibirica). Based on its stratigraphic position and inferred features of climate and vegetation, the latter of the two warm intervals identified in the Butovka pollen profile can be correlated with the Upper Volga Interstade in the Russian Plain, or the Brőrup Interstade in West Europe. We can also tentatively correlate it with warm DO event 23 as reflected in the oxygen isotope record from the Northern Greenland deep ice-core (North GRIP Members, 2004). A slighter and shorter warming within the first cold stage of the Early Valdai probably had an interphasial rank and corresponded to a shorter DO event 24 in the NorthGRIP oxygen-isotope curve.

Opis:
The Badenian Salinity Crisis took place at the early/late Badenian boundary and resulted in massive chemical sedimentation in the central Paratethys. The evaporating basin of the northern Carpathian Foredeep left behind gypsum and halite deposits tens of meters thick. As a very good medium for preservation, these evaporites are a fine source of diversified terrestrial palynomorphs. Plant communities reconstructed on the basis of both palynological analysis of sediments from the Bochnia and Wieliczka salt mines, as well as previously published studies from different localities within the evaporite basin, reveal the presence of wetland and mesic environments along the coasts of the northern part of the central Paratethys during the evaporative event. Among the most important taxa are Engelhardia, Ericaceae, Fagus, Liquidambar, Quercus, Taxodium/Glyptostrobus, Tricolporopollenites pseudocingulum, and Ulmus. The most characteristic feature of the palynofloras studied is the large amount (up to even 50%) of Ericaceae pollen in the spectra. Taxa representing a warm-temperate climate predominate in the palynofloras examined; however, representatives of a tropical/subtropical climate (i.a. Mastixiaceae) are also present. The presence of plant communities associated with wetland areas shows that the climate remained humid.

Opis:
A palynological study of recent sediments from Ijora Creek, an Urban Creek in Lagos, Southwestern Nigeria was carried out to provide inferences on paleovegetation and climate change over time in the study area. Two stations 90m apart were sampled at low tide in a boat using a Russian peat corer. Samples were taken at 10cm intervals and eighteen sediments samples were collected and processed using standard palynological methods. Two hundred and sixty six (266) and two hundred and thirty three (231) palynomorphs were recovered from stations 1 and 2 respectively. Palynomorphs recovered and identified to species level include Alchornea cordifolia, Hymenocardia acida, Elaeis guineensis, Spathodea companulata, Triumfetta pentandra, Uapaca acuminata, Tridax procumbens, Berlinia sp., Eugenia sp., Celtis sp., Albizia sp., Cyperus sp. together with species of Poaceae, Asteraceae, Arecaceae, Eurphorbiaceae, Acanthaceae, with common microforaminiferal test linings and fungal spores. Poaceae and fungal spores dominated the assemblage while station 1 recorded the highest pollen and spore abundance. The presence of microforaminiferal wall linings, fungal spores and the freshwater swamp species Alchornea cordifolia and the oil palm pollen Elaeis guineensis suggests a dominantly wet period in which, there was a marked marine transgression into the creek, interrupted occasionally by dry climate as inferred from the abundant records of Poaceae and Asteraceae. The presence of secondary forest species especially Elaeis guineensis suggests the impact of human activities on the paleovegetation.
