Palynofacies analyses from Bonyere Well No. 1 in the Tano basin, western Ghana has revealed five palynofacies associations (I – V) based on the percentage relative abundances of the sedimentary organic matter (SOM). The palynofacies associations reflect deposition in a fluvio-deltaic (oxic) environment, a distal dysoxic-anoxic shelf environment, a proximal dysoxic-suboxic environment, nearshore (oxic) and a fluvio-deltaic/nearshore environment with high oxygen levels and low preservation rates respectively. Based on marker palynomorphs, Campanian – Maastrichtian age has been assigned to sediments within the interval (1800-10 ft) – (90-100 ft), Turonian – Lower Senonian (Santonian) age between (3160-70 ft) – (1980-90 ft) and Aptian age between the interval (8140-50 ft) – (3340-50 ft). The absence of the elater-bearing pollen which are typical Africa-South America (ASA) elements for the Albian – Cenomanian age is indicative of an unconformity between the Aptian and Turonian sediments.

The results of palynological analyses of the Holocene deposits and modern pollen deposition in Poland and Finland are used to illustrate the progress in pollen analysis - the main palaeoecological method. The increased potential of modern palaeoecology for reconstruction of vegetation and for drawing conclusions on other environmental variables (climate, water conditions, landscape, anthropogenic disturbances) is demonstrated. Pollen analysis - develops at present interpretive tools for precise reconstruction of the structure and composition of vegetation and climate conditions. The progress consists in the quantitative presentation of pollenvegetation-climate relationships based on the examination of modern pollen deposition. The application of numerical analyses to pollen data allows correlating pollen spectrum features with the landscape/vegetation type. Special attention is paid to the Holocene vegetation changes of the transitional zone between boreal forest and tundra in the areas subjected to weak anthropopression (e.g. Lapland), which reflect climatic changes. Databases of modern pollen analogues are based on analysis of samples of surface mosses and contents of Tauber traps. These traps are used in Poland in investigations conducted as a part of the Pollen Monitoring Programme (http://pmp.oulu.fi). The correlation of Tauber-trap data with aerobiological ones contributes to understanding of the relationship between pollen production and climate elements. Additionally, the precise C14 dating allows a near-annual resolution in fossil deposits to be obtained more frequently. Due to time scales comprising hundreds of years, pollen analysis can provide means to resolve questions inaccessible for direct observation.

Investigation of mixed carbonate−siliciclastic Lower Devonian deposits have been carried out in the Ivanye Zolote and Ustechko sections in Podolia, Ukraine. Based on palynomorph evidence, the age of the samples studied is late Lochkovian, not older than the NM Oppel Miospore Zone, specifically the Si Lineage Zone. The presence of acritarchs and chitinozoans points to dominantly marine depositional conditions. However, a regressive environmental change toward more brackish conditions is indicated by a decrease in the taxonomic diversity of acritarchs in the topmost samples, the simultaneous disappearance of chitinozoans, and an increase in leiosphaerid frequency. Furthermore, evolution of limestone microfacies demonstrates a progressive transition from a shrinking marine basin toward a brackish, storm−affected muddy lagoon, manifested by recurrent profusion of impoverished, mostly opportunistic and euryhaline shelly benthos (nuculanid bivalves, leperditicopids and other ostracods, terebratulid brachiopods), chaetetid demosponges and diverse ichthyofauna. The association of plant (mainly nematophytes and some tracheids) and animal (eurypterid, ?scorpion, and possibly other arthropod) remains points to the presence of nearby Early Devonian wetland vegetation, providing food and shelter for various semi−aquatic and other terrestrial arthropods.

The objective of this study was to investigate the ranges of intra- and interindividual variability on the example of R. canina. For this purpose, four flowers were collected randomly (72 flowers in total)from 18 wild shrubs of R. canina growing in one population in Poznań (Poland)and then, from each flower, 50 correctly formed pollen grains (200 pollen grains per each individual)were selected. Inter- and intraindividual pollen grain variability was characterised based on 3600 pollen grains. They were analysed for seven quantitative features, i.e. length of polar axis (P), equatorial diameter (E), thickness of the exine along the polar axis (Exp), length of ectocolpi (Le) and P/E, Exp/P, and Le/P ratios. Our study revealed highly significant differences among flowers of the particular R. canina individuals with respect to all pollen grain biometrical features. In addition, it showed that the assessment of the full range of variability in pollen grain biometric features within one individual (shrub)was more reliable if we examined several pollen grains from several flowers than for the same number of pollen grains derived from a single flower. We also found statistically significant differences among particular individuals in all pollen grain features. This proves that in order to well characterise a population of a given species from the point of view of palynology, the plant material should derive from a possibly numerous number of individuals (shrubs).

The pollen morphology of eight species from three subgenera and five sections of the genus Allium L. was studied by LM and SEM (i.e.: A. angulosum, A. carinatum, A. senescens subsp. montanum, A. oleraceum, A. scorodoprasum, A. ursinum, A. victorialis and A. vineale). The material came from natural sites of these species located in Poland, Czech Republic, Austria and Italy. For measurements a sample consisted of 30 pollen grains. In total, 240 pollen grains were analysed. They were analysed in respect to six quantitative features (i.e.: length of long axis – LA, length of short axis – SA, thickness of exine along long axis – Ex, SA/LA and Ex/LA ratios and length of sulcus) and the following qualitative ones: pollen outline and shape, exine ornamentation. Taxonomic value of these pollen features is considerable, especially on the sections level. On the basis of these features, it is impossible to distinguish individual Allium species but only their groups. The examined features were characterized by moderate (LA, SA and SA/LA) or high variability (Ex, Ex/LA). Among studied species the lowest variability was found in A. victorialis and the highest in A. vineale and A. oleraceum.

Diverse carbonaceous microfossils, including exceptionally preserved remains of non−biomineralizing metazoans, are reported from a basal middle Cambrian interval of the Kaili Formation (Guizhou Province, China). The application of a gentle acid maceration technique complements previous palynological studies by revealing a larger size−class of acritarchs, a richer assemblage of filamentous microfossils, and a variety of previously unrecovered forms. Metazoan fossils include Wiwaxia sclerites and elements derived from biomineralizing taxa, including chancelloriids, brachiopods and hyolithids, in common with previously studied assemblages from the early and middle Cambrian of Canada. In addition, the Kaili Formation has yielded pterobranch remains and an assemblage of cuticle fragments representing “soft−bodied” worms, including a priapulid−like scalidophoran. Our results demonstrate the wide distribution and palaeobiological importance of microscopic “Burgess Shale−type” fossils, and provide insights into the limitations and potential of this largely untapped preservational mode.

I describe dispersed miospore assemblages recovered from 35 drill-core samples from Höllviken 2, Norrevång 1, and Svedala 1 wells, all in SW Scania, Sweden. Over eighty taxa of pollen and spores, ranging from the Aalenian to the Cenomanian were identified. Four pollen/spore zones have been defined on the basis of key taxa and on the variation in the frequency of miospore groups. The palynofacies analysis indicates that a continental depositional environment prevailed during the Aalenian in Scania. A stratigraphic hiatus existed from the Aalenian then on until the Valanginian, when the depositional environment subsequently became marine. The marine conditions continued until the Cenomanian. A gradual increase in marine palynomorphs is found in the Cenomanian succession, indicating a transgression. On the basis of the palynoflora it is suggested that the vegetation consisted of cycads, conifers, pteridophytes and a very limited number of angiosperms.
