An evaluatory study of the methods used in the reconstruction of historical vegetation and land-use, with reference to part of East Sussex, England
This thesis is directed towards an evaluation of the principal methods used in the reconstruction of historical vegetation and land use. It is argued here that previous reconstructions by many authors have employed only one or a very limited range of techniques, and that comparative evaluation of …

A computer aided palaeoecological study of selected Red Crag (Lower Pleistocene) gastropods
The thesis sets out to study the palaeoecology and palaeoethology of the Buccinidae, Muricidae, Naticidae and Turritellidae families of gastropods from the Red Crag (Lower Pleistocene), with particular reference to interactive fauna. The Red Crag is a fully marine deposit and contains large numbers …

Allergenic pollen concentrations in the United Kingdom
This study investigates the variations in the start and severity of the grass and birch pollen seasons at a network of sites in the United Kingdom. Daily grass and birch pollen concentrations have been monitored during the course of the study (1992-1994) at the University of North London site. …

Aeropalynology in North London
This study investigates the abundance and dispersal of pollen in an urban area with a view to making accurate predictions of daily pollen counts. Two-hourly pollen counts of more than 60 different pollen types have been recorded over four complete growing seasons in the heavily urbanized area of …

The palynology, palynofacies and palaeoenvironment of the early cretaceous Weald clay of Southeast England
This study attempts to show that cluster groupings of rock samples based on spore/pollen content in the Weald Clay represent particular palaeoenvironments.

Pollen stratigraphy of Holocene peat sites in Eastern Liguria, Northern Italy
This thesis presents the results of a research project designed to reconstruct the Holocene vegetation history of eastern Liguria. The study area lies within the northern Apennines, a region from which few detailed late Quaternary palaeoenvironmental records had boon published and prior to this …

Late-quaternary environmental change at Eastbourne, East Sussex
This study is an examination of the late-Quaternary palaeoenvironments of the Eastbourne area, The principal techniques employed are pollen, Foraminifera, Ostracoda, Mollusca and sediment particle size analyses. The lithostratigraphic investigation, using hand auger and a commercial drilling rig, …

Late Devensian and early Flandrian vegetational history and deglacial chronology of Western Argyll
The study attempted to assess, through the analysis of critically located pollen sites, the vegetational history of a region between Loch Etive and the Cowal Peninsula during the Lateglacial and early-postglacial periods, and to reconcile the varied reconstructions of Loch Lomond Readvance …

The sedimentology and palaeoecology of the Coralline Crag (Pliocene) of Suffolk
The Coralline Crag is a Pliocene, shallow marine, bioclastic sand formation with an outcrop restricted to south-east Suffolk. Four distinct sedimentary facies have been recognised which indicate that the Coralline Crag was deposited during a single marine transgression. The stratigraphically lowest …
