Biome reconstruction from pollen and plant macrofossil data provides an objective method to reconstruct past vegetation. Biomes for Africa the Arabian peninsula have been mapped 6000 years bp provide a new standard evaluation of simulated palaeovegetation distributions. A test using modern shows robustness biomization method, which is able predict major vegetation types with high confidence level. The application procedure set (pollen analyses) systematic differences present that are...
Surface sample pollen assemblages and vegetation data collected from two East Anglian fen carr sites with adjacent dry woodland belts are analysed to estimate the relevant source area of (RSAP) relative productivity (RPP) values for major canopy trees. The‘relevant pollen’ is found be on order 50-150 m, comparable but slightly greater than estimates forest hollow contexts in woodlands. Estimates Quercus then compared published south Sweden. Betula Corylus similar, some estimated taxa...
A high-resolution, multiproxy palaeolimnological record from the Manga Grasslands, northeastern Nigeria, spanning last 5500 calendar years, reveals episodic deterioration in Sahelian climate as significant biogeophysical thresholds were crossed. Desert-dust deposition began to increase 4700 cal. BP. Rainfall during summer-monsoon season declined permanently after 4100 further change atmospheric circulation, giving rise multidecadal centennial-scale droughts and enhanced dust deposition,...
ABSTRACT The temperate and boreal forests of Europe North America have been subject to repeated pathogen (fungal disease phytophagus insect) outbreaks over the last 100 years. Palaeoecology can, potentially, offer a long‐term perspective on such disturbance episodes, providing information their triggers, frequency impact. Mid‐Holocene declines in Tsuga Ulmus pollen dominate Quaternary literature forest pathogens, yet role even presence pathogenic fungal diseases, during these events has be...
Mediterranean oak-dominated agro-silvo-pastoral systems of southwestern Europe (called montado in Portugal and dehesa Spain) are semi-natural, savannah-style High Nature Value farmlands (HNVfs) shaped by centuries anthropogenic (e.g., cultivation, grazing) natural drought) disturbances. Therefore, changes grazing precipitation may alter their vegetation composition ecosystem properties impact upon long-term viability. We quantified the responses soil organic carbon (SOC) plant taxonomic...
A pollen diagram has been produced from the base of Caburn (East Sussex) that provides a temporally and spatially precise record vegetation change on English chalklands during mid-Holocene (ca. 7100 to ca. 3800 cal. yr BP). During this period slopes above site appear have well-wooded, with analogous modern Fraxinus–Acer–Mercurialis communities in which Tilia was also prominent constituent. However, scrub grassland taxa such as Juniperus communis, Cornus sanguinea Plantago lanceolata are...
Abstract Aim This study aims to separate regional and local controls on Holocene vegetation development examine how well pollen records reflect climate change in a semi‐arid region. The relative importance of human activity as agents the Sahel during late is also considered. Location Jikariya Lake, an inter‐dune depression Manga Grasslands north‐eastern Nigeria. Methods Pollen charcoal were used provide record history. Palaeoclimate hydrological changes reconstructed from sedimentary...
This paper presents a synthesis of results from investigations into palaeolimnology and dune chronology in the Manga Grasslands adjacent areas NE Nigeria, order to reconstruct evolution this semi-arid landscape since late glacial. A marked wet phase gave way fall lake levels during Dune emplacement was active at time south Grasslands, but seems have been absent grasslands themselves. Wet conditions prevailed much early mid-Holocene, accompanied by periods significant barchanoid reactivation....
Methods of reconstructing changes in plant traits over long time scales are needed to understand the impact changing environmental conditions on ecosystem processes and services. Although Holocene pollen have been extensively used provide records vegetation history, few studies adopted a functional trait approach that is pertinent processes. Here, for woody herbaceous fen peatland communities, we use modern data combined with from deposits reconstruct dynamics. The six chosen (measures leaf...
summary The results of palaeoecological analyses and lithostratigraphic investigations are used to reconstruct the Flandrian evolution a valley in East Sussex Weald, Brede. Particular emphasis is placed upon mid‐Flandrian vegetational history. Palynological data collected from one site, Brede Bridge, include detailed resolution declines Ulmus Tilia pollen. Predominantly inorganic sediments were deposited during early Flandrian. Marine conditions penetrated lower under general influence sea...
SUMMARY Pollen data, plant macrofossil remains and lithostratigraphy are used to reconstruct Flandrian vegetational history from a coastal site in south‐eastern England. The record at this site, Pannel Bridge East Sussex, extends back c. 10000 BP is the most complete so far obtained region. thirteen pollen assemblages zones defined reflect, part, complex development of site. Prior 8500 BP, wetland valley was localized around Between 6000 response changes configuration, such areas underwent...
