“…Comparing with the data presented by Van Geel et al (1986), the Hooge Broek spectra agree most with their level 20.5 m spectrum, which is in the upper part (E5b) of the E5 zone. The largest deviations concern our values of Picea (9.2 and 2.5 vs. 18%), Pinus (10.8 and 6.5 vs. ca.…”

“…Most of the common species, except Anomodon viticulosus, also have been found in the nearby Eemian site of Kamphuis (Van Geel et al 1986). This site and the Eemian site of Oerel, Germany (Behre et al 2005) yielded various mosses that might have grown in or close to water (Amblystegium, Calliergon, Calliergonella, Campylium elodes, Drepanocladus, Tomenthypnum nitens, Scorpidium), but the Hooge Broek sample does not contain any hydrophytic species, which is in contrast to the macrofossil remains and palynomorphs.…”

“…As in the study by Van Geel et al (1986), which provides detailed data of the nearby Late Eemian locality Kamphuis near Denekamp, the total of tree and shrub pollen (R pollen) was used for percentage calculations (Table 4). The most important R pollen taxa are Alnus (Fig.…”

“…Pollen sequences from the Peel area were published by Eshuis (1946) and Florschütz and Anker-van Someren (1956), and the pollen data from Amersfoort, Farmssum and Moershoofd are well known (Zagwijn 1961). Further contributions are those by Van Geel et al (1986, 1995 pollen, fungal spores and macrofossils), Van Leeuwen et al (2000;pollen) and Cleveringa et al (2000;pollen). The data from the localities near Deventer, Zutphen and Zwolle were mentioned by Burck (1949) as palaeobotanical evidence for his Eemian clay-peat bed.…”

The Kreftenheye Formation is a fluviatile deposit occurring in the central part of the Netherlands. The present study deals with the plant remains found in suctiondredged bulk samples from its largely Eemian Zutphen Member, a clayey sediment formerly known as the claypeat bed or the Salvinia bed. It reports the discovery of a large number of galls induced by the asexual generation of the currently southeast European oak gall wasp Andricus hungaricus. The associated plant remains include seeds, fruits, conifer cones, wood, spines, leaf fragments, buds, bud scales, stem fragments, bryophytes, sporangia, oospores, palynomorphs, galls, jet and amber. The palynomorph samples indicate the Late Eemian pollen zone E5b of the Carpinus phase as the origin of the galls, but the other macrofossils may have a wider stratigraphic range, including possibly also material from (a part) of the zones E3-E5a. Several elements, such as Celtis, Chamaecyparis, Juglans, Magnolia and Pterocarya, date almost certainly from earlier interglacials. The list of plant remains is dominated by fresh water plants, riparian elements and ancient woodland taxa, which reflects the ecological range of the IJssel valley and adjacent ice-pushed ridges very well. Thermophilous elements include Brasenia schreberi, Buxus sempervirens, Cornus mas, Najas minor, Salvinia natans, Trapa natans and possibly also Andricus hungaricus. Quercus cerris, the probable host of the sexual generation of A. hungaricus was not found.

Palynological studies including records of non-pollen palynomorphs (NPP) are uncommon in the Neotropics, in spite of their demonstrated usefulness in other regions. Modern analog studies to improve palaeoecological interpretations of NPP are even more scarce. Here, we report the NPP assemblages recorded in modern surface samples from an altitudinal transect of the Venezuelan Andes, ranging from about 2300 and 4600 m. We compared the assemblages with the results of previous pollen analyses of the same samples. The variables considered to explain NPP patterns along the transect are altitude and the local habitat of the sampling site ("sample type"). A total of 65 NPP taxa -classified into algal and zoological remains, and fungal spores -have been found. Unidentified taxa (23) have been named with a code, depicted and described for further reference. Fungal spores are well represented along the whole transect, whereas algal and zoological remains are absent or very scarce in the lower and the uppermost ranges. The altitudinal zonation of fungal spores matches with that of pollen and the corresponding vegetation belts, suggesting a close relationship. The known environmental requirements of some of the fungi identified allowed inferences on particular ecological features, in agreement with previous palynological interpretations. Both elevation and sample type are needed to explain the observed differences in the assemblages of the three groups, the elevation being more decissive for fungal spores and the local habitat of the sampling site for algal and zoological remains. The sample type effect is minimised when the NPP studied are considered altogether, thus increasing their usefulness as palaeoecological proxies. This study reinforces the utility of modern analog surveys of NPP with palaeoecological purposes and encourages further research, particularly in poorly known areas, as for example tropical regions.
