Sample details on OSL data for aeolian sediments in north-eastern part of European Sand Belt

2019

A compilation of previously published and unpublished absolute age (OSL and TL) determinations of aeolian sediments from the north-eastern part of European Sand Belt. Contains age, error, sampling depth, location etc. and a reference to data source. Coordinates of sampling locations for contemporary publications are taken from field observations (GPS), but older ones - published schematic maps. Data set is created according to schema of DATED-1 database (https://doi.org/10.1594/PANGAEA.848117).

Evaluation of a technical revegetation action performed on foredunes at Devesa de la Albufera, Valencia, Spain

2010

We have evaluated the level of restoration achieved by a technical revegetation action carried out on reconstructed foredunes at the Devesa de la Albufera and compared this level with that achieved by spontaneous succession. Foredunes 1, 3, 6 and 20 y old since revegetated (1, 3, 6 and 20 y, respectively) were considered as spatially separated stages representing a successional trend in the development of the restored plant community. Lower and similar levels of diversity (richness and H´ and Pielou´s indexes) and coverage, respectively, were found on dunes corresponding to the oldest stage of technical revegetation compared with that of the reference site. Diversity and coverage parameters…

Sedimentary features reveal transport paths for Holocene sediments on the Kristianstad coastal plain, SE Sweden.

2017

AbstractWe have investigated coastal and aeolian deposits on the Kristianstad plain in southernmost Sweden by a combination of methods that has yielded data on sedimentary features such as grain-size variations, shape and character of quartz grain surfaces (determined in light microscope and scanning electron microscope), and mineralogical composition. Such sedimentary techniques have been not applied to coastal deposits in this part of the Baltic Sea region before. The littoral, foredune and parabolic dune sands are sedimentologically similar, only a slight grain-size transformation by aeolian processes in the foredune was observed. Sand in straight-crested dunes, on the other hand, origin…

Recolonization after habitat restoration leads to decreased genetic variation in populations of a terrestrial orchid.

2012

Colonization is crucial to habitat restoration projects that rely on the spontaneous regeneration of the original vegetation. However, as a previously declining plant species spreads again, the likelihood of founder effects increases through recurrent population founding and associated serial bottlenecks. We related Amplified Fragment Length Polymorphism markers genetic variation and fitness to colonization history for all extant populations of the outcrossing terrestrial orchid Dactylorhiza incarnata in an isolated coastal dune complex. Around 1970, D. incarnata suffered a severe bottleneck yet ultimately persisted and gradually spread throughout the spatially segregated dune slacks, aided…

Geomorphological environment: dunes in Agrigento coast

2008

[ITA] La fascia costiera di San Leone (Agrigento-Siclia). è costituita da una spiaggia sabbiosa delimítala verso terra da un complesso dunale di particolare pregio. L'assetto geomorfologico di questo litorale è stato inlluenzato dal forte grado di antropizzazione del luogo. La fascia costiera nel tempo ha súbito degli avanzamenti e arreiramenti. Sono stati quindi analizzati e proposti alcuni rimedi. mirali alia ricostruzione. al mantenimenlo e alia diíesa della duna.

Baudemont, le Pré-de-la-Bordonne (Saône-et-Loire) : sépultures et mobilier danubien de la première moitie du ve siècle

2020

A necropolis at Baudemont (Saône-et-Loire) that was partially excavated in 1894 has revealed approximately fifteen graves datable to the end of the 4th and 5th centuries ad. Others seem to have been emptied during the first half of the 19th century. The discovery of a negative of the objects collected in 1894 indicates the pieces originating in the danubian area, which probably reflects the presence of a group of eastern Germans among those buried in the necropolis. These discoveries offer new perspectives on the Gallic context during the 5th century.

What do leaf anatomy and micromorphology tell us about the psammophilous Pancratium maritimum (Amaryllidaceae) in response to sand dune conditions?

2015

Abstract The present study aimed at verifying the morphological variation in leaf traits among different populations of Pancratium maritimum (sea daffodil) and the correlation between leaf diversity and climate conditions at different sites. Eleven populations of P. maritimum from Mediterranean coastal sand dunes were investigated with respect to leaf surface micro-morphology, leaf anatomy, and vascular pattern. Morphometric analysis was based on 29 quantitative foliar parameters. One-way analysis of variance (ANOVA), principal component analysis (PCA), discriminant function analysis (DFA), and clustering by Ward’s method were used for the statistical evaluation. Results revealed a rather u…

<p><strong><em>Scutellospora deformata</em></strong><strong> (Scutellosporaceae), a new species of Gigasporales f…

2021

A new species S. deformata, that occurs in six locations of marine sand dunes along the eastern Mediterranean coast of Spain is described and illustrated from spores. In the field, the species occurred in the rhizosphere of Ammophila arenaria (Poaceae), Elymus farctus (Poaceae), Otanthus maritimus (Asteraceae), and Echinophora spinosa (Apiaceae). Morphological characters related with outer, middle and inner wall of the glomerospores as well as phylogenetic analysis (partial SSU, ITS1-5.8S region and the partial LSU nrDNA) support the hypothesis that the fungus is a new species of the Scutellosporaceae.
