Showing papers in "Review of Palaeobotany and Palynology in 1988"

TL;DR: A discussion of the West- and Central European species of the natural genus Autunia Krasser and the form-genus Rhachiphyllum Kerp is presented, and a number of callipterid species previously introduced in the palaeobotanical literature appear to be synonymous with the here accepted and described taxa.

TL;DR: This article investigated Sumatran and Javan sites at intermediate altitudes and found evidence of a greater abundance of gymnosperms and higher altitude vegetation around the sites from at least 18,200 to 12,400 yr B.P, which suggests that forest altitudinal boundaries were much lower than today's.

TL;DR: Assemblages of dinoflagellate cysts of Cenomanian-Turonian age recovered from sequences containing bituminous marls in the Lower Saxony Basin, Helgoland and eastern England vary in composition according to lithofacies and palynofacies.

TL;DR: This paper provided relatively detailed vegetational, geomorphological and sea level histories for a variety of coast types inhabited by mangrove and saltmarsh plants, and showed that these vegetation types contain prolific pollen producers.

TL;DR: DiMichele et al. as mentioned in this paper found that Lycopods dominate the peat-swamp flora, as at other Herrin Coal sites, with Lepidophloios hallii being the most important (30-78% of whole-profile peat biomass). Ferns (5-15% biomass), and pteridosperms (1 15% biomass) also are important in the swamp flora.

TL;DR: In this article, the authors compare three pollen diagrams from cores sampled at the bottom of the Lac du Bouchet (Massif Central, France) permit a synthetic biostratigraphical sequence to be established, focusing on the lower part of the borings that partly covers the Middle Wurm.

TL;DR: A new family, diplopsalidaceae, a new species, Gotoius abei sp.

TL;DR: In this article, an improved understanding of the pollen signal in the marine sediments offshore of northwest Africa is applied to deep-sea core M 16017-2 at 21°N.

TL;DR: In this article, an 8.5 m sediment core from Yaguarcocha, a 2.5 km long volcanic lake, yields the first long pollen history of the American ecuador.

TL;DR: Improved knowledge on Callipteris has led to the belief that, in a strictly morphological sense, the genus represents a highly heterogeneous group, and the genus Autunia Krasser is emended to include both vegetative and reproductive organs, thus gaining a natural status.

TL;DR: The relationship between the fungus and its arboreal hosts at Egernsund ( Tilia, Fraxinus ) reflects the weak parasitic character of the fungus.

TL;DR: In this article, the authors used the MISEDOR well to locate the Plio-Pleistocene boundary at a depth of about 400 m. This limit is confirmed by the contrast between the uniformity of the paleogeographical features below this depth and the great variability of the environmental conditions indicated above it.

TL;DR: In this article, the authors propose formal lithostratigraphical units for three palaeolakes at elevations from 44 m a.s. to 30 m a s.l. all have marine sediments in the lower part of the sequences, with lacustrine sediments above.

TL;DR: In this article, the results of fossil pollen studies in Eastern, Central and Southern Africa covering the last 32,000 years are surveyed and the interpretation of the results in terms of former vegetation poses difficult questions.

TL;DR: In this article, the Cretaceous/Tertiary boundary interval of the El Haria section, near El Kef, northwest Tunisia, was studied and a latest Maastrichtian-earlier Danian (unnamed) interval and an early Danian Danea californica Biozone was recognized.

TL;DR: Paleoecological investigations of a cordaitalean-dominated coal-ball deposit from Urbandale, Iowa, of Middle Pennsylvanian age, suggests that cordaitales were the first peat-forming community preserved within coal balls from this deposit as mentioned in this paper.

TL;DR: Pollen profiles have been obtained from sediment cores taken in three old river channel lakes in the western Amazon basin of Ecuador as mentioned in this paper, showing that a detailed pollen record of Amazonian forests is preserved.

TL;DR: Peridinioid dinoflagellates from the Late Campanian of Egypt revealed important morphologic alterations caused by routine palynological extraction techniques, including the presence of a very resistant background microflora, consisting mainly of small acritarchs and prasinophyceans.

TL;DR: In this paper, the authors consider the various published dinoflagellate cyst biozonation schemes for European late Palaeocene and earliest Eocene sediments and assess the alternative synonymous approaches.

TL;DR: The affinities of this fern are considered together with a discussion of the paleoecology.

TL;DR: Palynological studies of two cores 7.5 m deep from Lake Guiers in Senegal, at 16°N, gave evidence of the mangrove development at the lake area around 6000 yr B.P., as also of the extension northwards of the Sudanian to Guinean zones of humid vegetation as discussed by the authors.

TL;DR: In this paper, rich and well preserved marine palynofloras are recorded from the Middle and early Upper Jurassic strata on Kongsoya, Kong Karls Land, Norway.

TL;DR: In this paper, the evolution of upland swampy savanna with luxuriant herbaceous cover in Sandynallah, in the Nilgiri hills of southern India, from the initial swampy or per-humid stage through humid, semihumid and arid phases of dense, sparse to poor herbaceous vegetation respectively, is inferred from the pollen analytical data.

TL;DR: Assemblages of abundant, well preserved and taxonomically diverse chitinozoans and acritarchs occur in the Ordovician-Silurian portion of the Arabian Palaeozoic stratigraphic section.

TL;DR: Palynological analyses of samples from a fluvioglacial terrace in the periglacial belt of the Paramo de Miranda suggest that temperatures increased at the beginning of the Holocene, the vegetation attaining a density similar to that of the present, although with fewer species.

TL;DR: A key to the convergent striate pollen and palynomorph types — Spathiphyllum (Araceae), Ephedra, Ephedripites, Equisetosporites and Cornetipollis — chiefly based upon their ultrastuuctural details, is furnished.

TL;DR: In this paper, a late Holocene record of lowland swamp and marsh stratigraphy and paleoecology has been obtained from Kosrae, Eastern Caroline Islands, and limited recovery confirms that this is a progradational sequence formed over coral lagoons during postglacial sea level rise, also seen in other parts of the Pacific.

TL;DR: In this article, seven species of Beauprea (Proteaceae), endemic to New Caledonia, fall into two distinct morphological groups based on the presence or absence of sculptural elements.

TL;DR: Weather affected the normal pattern, and each species responded differently to variations in weather factors suggesting that anther dehiscence in them might have adapted through a genetic make-up to certain evaporating power of the air.

TL;DR: The family Polygonaceae consists of some 40 genera with ca. 800 species and their distribution is mostly in the northern and temperate regions of the USA and Canada.
