Zonation of the geochemical element data was conducted using the constrained incremental sum of squares (CONISS) function in TILIA v.1.7.16. Biological proxies. For diatom analyses, 19 sediment samples of CORE2 were treated by adding hydrogen peroxide (30%) to 5 mg of freeze-dried material and heating in a water bath to degrade the organic material and retain the diatoms. The diatom community. Pollen zonation was conducted by Constrained Incremental Sum of Squares Cluster Analysis (CONISS, TILIA 2.0.41, with dendrogram scale of total sum of squares) including all counted pollen and spore taxa . All pollen and spore taxa were included in the pollen sum (ranging between 145 and 347 with an average of 290 per sample) used to calculate pollen percentages. Pollen concentration was.

The palynomorph distribution diagrams have been further divided into zones by stratigraphically constrained cluster analysis using CONISS (Grimm, 2004) available in Tilia TG View 2.0.2 software (Grimm, 2004) in conjugation with the changes in the percentage of some important taxa.

The number of significant zones was determined by the broken stick method (Bennett 1995).

Pollen diagram was constructed with TILIA 2.0.41 (Grimm, 2015). Pollen zonation was conducted by Constrained Incremental Sum of Squares Cluster Analysis (CONISS, TILIA 2.0.41) including all counted taxa. All pollen taxa were included in the pollen sum used to calculate pollen percentages. 95% confidence intervals were calculated following Maher (1972). Micro-charcoal analysis was conducted on. The spread of wheat and barley involves evolutionary and human adaptation but has been difficult to date properly. Findings from a cave site suggest a much earlier transfer of cereal grains across. defined by a TILIA classification (E. Grimm, Illinois State Museum, Springfield, Illinois) into groups using the agglomerative cluster analysis method of incremental sum of squares (CONISS) with a square root transformation (Grimm 1987). We recognised zones at the second, third, and, occasionally, fourth levels of division by CONISS, generally aiming to divide each profile into 3-5 zones. To.

Tilia 2.0.41 software was used for plotting diagrams. CONISS cluster analysis was employed as an additional tool to eye-matching for defining diatom zones (Grimm, 1987). Carbon and nitrogen determination. The C/N ratio is useful for indicating the type and source of organic matter (Rice and Hanson, 1984). Variations in C/N ratio can occur because algae are enriched in nitrogen and depleted in. Diatom zones were created down the sediment core by cluster analysis (following square root transformation) which used a temporally constrained incremental sum of squares (CONISS) analysis in the program Tilia v. 1.5.12 (Edwards and Cavalli-Sforza's chord distance). 4 RESULTS 4.1 Meteorological dat

An unconstrained cluster analysis routine was used to objectively define local pollen assemblage zones (lpz), using the CONISS option within the computer programme TILIA v1.12; the resultant dendrograms have been omitted from the pollen diagram to aid clarity.

Introduction The Schirmacher Oasis (70°44'21-70°46'04S to 11°26'03-11°49'54E), a 25 km long and 3 km wide ice-free plateau along the Princess Astrid Coast in Dronning Maud Land, East Antarctica, consists of more than 100 freshwater lakes, including epishelf, land-locked and proglacial. TILIA software was used to draw the pollen spectra, in which a CONISS module was used to calculate distances and cluster zoning based on the square root transformation of the pollen percentage data. Detrended correspondence analysis (DCA) and principal component analysis (PCA) have been widely used in forest ecosystem, shrub communities, meadow grasslands, and other vegetation researches [ 16.

Clusters of similar pollen spectra were identified using CONISS; the results were used to delimit pollen zones. Results were plotted using PC-based software TILIA and TILIA GRAPH .

The Eemian vegetation succession is fairly well characterised and has parallels across western parts of Europe (Turner, 2000). The pattern of appearance and culmination of tree pollen during the Eemian shows one of the most distinctive interglacial successions (Menke and Tynni. The data were analysed with TILIA and CONISS. Early Holocene, Zone I, 9800-8500 BP. Conspicious oscillations are registered of the Pine forest and the moist forest, with Alnus as an important element. The oak forest remains constant. These changes correspond changes from a humid temperate climate to a temperate subhumid climate, supported by the presence of Abies. Lower mid Holocene, zone II. Understanding the processes that led to the recent evolution of Mediterranean landscapes is a challenging question that can be addressed with paleoecological data. Located in the White Mountains of Crete, Asi Gonia peat bog constitutes an exceptional 2000-years-long sedimentary archive of environmental change. In this study, we document the making of the White Mountains landscape and assess. Calculations and visualizations were made using the Tilia software . If pollen or seeds were very rare, finds are visualized by a plus (+) symbol. Pollen types with low percentages but with an indicative value were exaggerated five times. This is indicated by an open curve on top of a solid curve. Zonation of the diagram is derived from the CONISS calculations . These calculations are based on.
