In de plooien van vele molaren bevonden zich gekauwde plantenresten en daarbij ook microfossielen. We determineerden pollen (stuifmeel) en sporen en interpreteren op basis hiervan voedselkeuzes en de mogelijke effecten op de pollenspectra als een deel van het bloeiseizoen vertegenwoordigd is. We bediscussieren ook de effecten van de veranderende vegetatiesamenstelling in relatie tot het klimaat en de ouderdom van de molaren. Verschillende factoren hebben bijgedragen aan de samenstelling van het pollen. Toch geven de pollenspectra een beeld van de v...

Pollen, spores, non-pollen palynomorphs, mosses, other botanical macrofossils and insect remains were recorded for reconstructions of changing environmental conditions. Eastern West-Frisia was a cultivated landscape during the Bronze Age, but it became a freshwater wetland in the Late Bronze Age. In most of our sites, radiocarbon dates show that time transgressive inundation of soils preceded the climate shift at 850 cal BC for several centuries. We suggest that solar forcing of climate change may have delivered the final push to the inundation and depopulation of West-Frisia, which had already commenced several centuries before, due to sealevel rise. We did not find evidence for significant Bronze Age tree growth in West-Frisia before the inundations. Vegetation successions in the new wetlands developed from shallow mineral-rich freshwater to rich-fen vegetation. Subsequently poor fen vegetation with ...

Research paper thumbnail of Human impact and ecological changes in lakeshore environments. The contribution of non-pollen palynomorphs in Lake Banyoles (NE Iberia)

The study of a core from Lake Banyoles (Girona, NE Iberia) enabled the reconstruction of ecological changes and assessment of human impact in a lakeshore environment during the Mid-Holocene. This work aims to fill the gap in knowledge about the ecological significance of NPP in lowland areas in NE Iberia, and provides descriptions and illustrations of new types documented. Deforestation induced by Early Neolithic communities caused the proliferation of lignicolous fungi in decaying wood and an increase in soil erosion. The input of allochthonous mud led to higher turbidity in the lake water, causing a succession in aquatic organisms, from cyanobacteria to green algae. In that context, a group of erosion-associated fungal spore types were recorded. Indicators of soil disturbance and coprophilous fungi were recorded from 5000 to 4200 cal BP, linked with local habitation during the Late Neolithic–Chalcolithic. The NPP analysis reflects the significant human impact that caused changing local environmental conditions, consistent with the signals based on pollen analysis.
